 - `pkh(KEY)` (not inside `tr`): P2PKH output for the given public key (use `addr` if you only know the pubkey hash).
 - `wpkh(KEY)` (top level or inside `sh` only): P2WPKH output for the given compressed pubkey.
 - `combo(KEY)` (top level only): an alias for the collection of `pk(KEY)` and `pkh(KEY)`. If the key is compressed, it also includes `wpkh(KEY)` and `sh(wpkh(KEY))`.

   - This update should be reviewed with a reindex-chainstate with assumevalid=0 to catch any defect
      that causes rejection of blocks in the past history.
 - Clear the release notes and move them to the wiki (see "Write the release notes" below).
-- Translations on Transifex
+- Translations on Transifex:
+    - Pull translations from Transifex into the master branch.
     - Create [a new resource](https://www.transifex.com/bitcoin/bitcoin/content/) named after the major version with the slug `[bitcoin.qt-translation-<RRR>x]`, where `RRR` is the major branch number padded with zeros. Use `src/qt/locale/bitcoin_en.xlf` to create it.
     - In the project workflow settings, ensure that [Translation Memory Fill-up](https://docs.transifex.com/translation-memory/enabling-autofill) is enabled and that [Translation Memory Context Matching](https://docs.transifex.com/translation-memory/translation-memory-with-context) is disabled.
     - Update the Transifex slug in [`.tx/config`](/.tx/config) to the slug of the resource created in the first step. This identifies which resource the translations will be synchronized from.

Subject: [PATCH 0032/1725] ci: Switch from bionic to buster

This change is a prerequisite for the following bumping Qt minimum
version to 5.11.3. It is required as bionic has Qt 5.9.5.

Effectively, this also changes:
- gcc from 8.4.0 to 8.3.0
- python from 3.6.5 to 3.7.3

+
+## Conventions
+
+- Most libraries are internal libraries and have APIs which are completely unstable! There are few or no restrictions on backwards compatibility or rules about external dependencies. Exceptions are *libbitcoin_consensus* and *libbitcoin_kernel* which have external interfaces documented at [../shared-libraries.md](../shared-libraries.md).
+
+- Generally each library should have a corresponding source directory and namespace. Source code organization is a work in progress, so it is true that some namespaces are applied inconsistently, and if you look at [`libbitcoin_*_SOURCES`](../../src/Makefile.am) lists you can see that many libraries pull in files from outside their source directory. But when working with libraries, it is good to follow a consistent pattern like:
+
+  - *libbitcoin_node* code lives in `src/node/` in the `node::` namespace
+  - *libbitcoin_wallet* code lives in `src/wallet/` in the `wallet::` namespace
+  - *libbitcoin_ipc* code lives in `src/ipc/` in the `ipc::` namespace
+  - *libbitcoin_util* code lives in `src/util/` in the `util::` namespace
+  - *libbitcoin_consensus* code lives in `src/consensus/` in the `Consensus::` namespace
+
+## Dependencies
+
+- Libraries should minimize what other libraries they depend on, and only reference symbols following the arrows shown in the dependency graph below:

+
+**Dependency graph**. Arrows show linker symbol dependencies. *Consensus* lib depends on nothing. *Util* lib is depended on by everything. *Kernel* lib depends only on consensus and util.
+
+</td></tr></table>
+
+- The graph shows what _linker symbols_ (functions and variables) from each library other libraries can call and reference directly, but it is not a call graph. For example, there is no arrow connecting *libbitcoin_wallet* and *libbitcoin_node* libraries, because these libraries are intended to be modular and not depend on each other's internal implementation details. But wallet code still is still able to call node code indirectly through the `interfaces::Chain` abstract class in [`interfaces/chain.h`](../../src/interfaces/chain.h) and node code calls wallet code through the `interfaces::ChainClient` and `interfaces::Chain::Notifications` abstract classes in the same file. In general, defining abstract classes in [`src/interfaces/`](../../src/interfaces/) can be a convenient way of avoiding unwanted direct dependencies or circular dependencies between libraries.
+
+- *libbitcoin_consensus* should be a standalone dependency that any library can depend on, and it should not depend on any other libraries itself.
+
+- *libbitcoin_util* should also be a standalone dependency that any library can depend on, and it should not depend on other internal libraries.
+
+- *libbitcoin_common* should serve a similar function as *libbitcoin_util* and be a place for miscellaneous code used by various daemon, GUI, and CLI applications and libraries to live. It should not depend on anything other than *libbitcoin_util* and *libbitcoin_consensus*. The boundary between _util_ and _common_ is a little fuzzy but historically _util_ has been used for more generic, lower-level things like parsing hex, and _common_ has been used for bitcoin-specific, higher-level things like parsing base58. The difference between util and common is mostly important because *libbitcoin_kernel* is not supposed to depend on *libbitcoin_common*, only *libbitcoin_util*. In general, if it is ever unclear whether it is better to add code to *util* or *common*, it is probably better to add it to *common* unless it is very generically useful or useful particularly to include in the kernel.
+
+
+- *libbitcoin_kernel* should only depend on *libbitcoin_util* and *libbitcoin_consensus*.
+
+- The only thing that should depend on *libbitcoin_kernel* internally should be *libbitcoin_node*. GUI and wallet libraries *libbitcoinqt* and *libbitcoin_wallet* in particular should not depend on *libbitcoin_kernel* and the unneeded functionality it would pull in, like block validation. To the extent that GUI and wallet code need scripting and signing functionality, they should be get able it from *libbitcoin_consensus*, *libbitcoin_common*, and *libbitcoin_util*, instead of *libbitcoin_kernel*.
+
+- GUI, node, and wallet code internal implementations should all be independent of each other, and the *libbitcoinqt*, *libbitcoin_node*, *libbitcoin_wallet* libraries should never reference each other's symbols. They should only call each other through [`src/interfaces/`](`../../src/interfaces/`) abstract interfaces.
+
+## Work in progress
+
+- Validation code is moving from *libbitcoin_node* to *libbitcoin_kernel* as part of [The libbitcoinkernel Project #24303](https://github.com/bitcoin/bitcoin/issues/24303)
+- Source code organization is discussed in general in [Library source code organization #15732](https://github.com/bitcoin/bitcoin/issues/15732)

Subject: [PATCH 0046/1725] contrib: refactor: replace `hex_switchEndian` in
 linearize scripts

Switching the endianness of a hex string `str` can simply be
achieved by `bytes.fromhex(str)[::-1].hex()`, i.e. we can use
that and remove those helper methods.

Subject: [PATCH 0048/1725] test: checks for tracepoint tests

For testing the USDT tracepoint API in the functional tests we
require:
 - that we are on a Linux system*
 - that Bitcoin Core is compiled with tracepoints
 - that bcc and the the Python bcc module [0] is installed
 - that we run the tests with the required permissions**
otherwise we skip the tests.

*:  We currently only support tracepoints on Linux. Tracepoints are
    not compiled on other platforms.
**: Currently, we check for root permissions via getuid == 0. It's
    unclear if it's even possible to run the tests a non-root user
    with e.g. CAP_BPF, CAP_PERFMON, and access to /sys/kernel/debug/
    tracing/. Anyone running these tests as root should carefully
    review them first and then run them in a disposable VM.

Subject: [PATCH 0055/1725] Respond to getheaders if we have sufficient
 chainwork

Previously, we would check to see if we were in IBD and ignore getheaders
requests accordingly. However, the IBD criteria -- an optimization mostly
targeted at behavior when we have peers serving us many blocks we need to
download -- is difficult to reason about in edge-case scenarios, such as if the
network were to go a long time without any blocks found and nodes getting
restarted during that time.

To make things simpler to reason about, just use nMinimumChainWork as our
anti-DoS threshold; as long as our chain has that much work, it should be fine
to respond to a peer asking for our headers (and this should allow such a peer
to request blocks from us if needed).

Subject: [PATCH 0057/1725] blockstorage: Make m_block_index own CBlockIndex's

Instead of having CBlockIndex's live on the heap, which requires manual
memory management, have them be owned by m_block_index. This means that
they will live and die with BlockManager.

A change to BlockManager::LookupBlockIndex:
- Previously, it was a const member function returning a non-const CBlockIndex*
- Now, there's are const and non-const versions of
  BlockManager::LookupBlockIndex returning a CBlockIndex with the same
  const-ness as the member function:
    (e.g. const CBlockIndex* LookupBlockIndex(...) const)

See next commit for some weirdness that this eliminates.

The range based for-loops are modernize (using auto + destructuring) in
a future commit.

Subject: [PATCH 0072/1725] [miner] always assume we can create witness blocks

Given the low possibility of a reorg reverting the segwit soft fork,
there is no need to check whether segwit is active here. Also,
TestBlockValidity is run on the block template after it has been
created.

Subject: [PATCH 0082/1725] net, init: assert each network reachability is true
 by default

The default network reachability values are implicitly set
by this line in net.cpp:

static bool vfLimited[NET_MAX] GUARDED_BY(g_maplocalhost_mutex) = {};

This commit asserts that each network is reachable during
the first loop through them during bitcoind init.

Subject: [PATCH 0085/1725] util: Add GetPathArg default path argument

Let GetPathArg method be used more places for path arguments that have
default values, like "-settings" and BITCOIN_SETTINGS_FILENAME in the
next commit.

Also:

- Fix negated argument handling. Return path{} not path{"0"} when path
  argument is negated.

- Add new tests for default and negated cases

- Move GetPathArg() method declaration next to GetArg() declarations.
  The two methods are close substitutes for each other, so this should
  help keep them consistent and make them more discoverable.

Subject: [PATCH 0096/1725] test: Correctly decode UTF-8 literal string paths

Call fs::u8path to convert some UTF-8 string literals to paths, instead
of relying on implicit conversions. The implicit conversions incorrectly
decode const char* paths using the current windows codepage, instead of
treating them as UTF-8. This could cause test failures depending what
environment windows tests are run in.

Subject: [PATCH 0106/1725] tests: Ensure sorted/multi_a descriptors always
 generate different addrs

Sometimes the multi_a and sortedmulti_a descriptors will produce some of
the same addresses in the tests. This causes the wallets to start
generating addresses at a different index as they detect that one of
the addresses is used. This subsequently causes a test failure.

To avoid this problem, use descriptors that will produce unique
addresses by putting one of the multi_a in a different branch.

Subject: [PATCH 0108/1725] guix: only use native GCC 7 toolchain for Linux
 builds

The macOS and Windows builds do not require a GCC 7 toolchain, and this
is actually causing build issues, i.e #24211. So switch to using a GCC
10 native toolchain for both.

Subject: [PATCH 0110/1725] test: Add tests for GetArg methods / settings.json
 type coercion

Just add tests. No changes to application behavior. Tests will be
updated in the next commit changing & improving current behavior.

Include a Qt test for GUI startup crash reported by Rspigler in
https://github.com/bitcoin/bitcoin/issues/24457 caused by GetArg
behavior that happens if settings.json contains an integer value for any
of the configuration options which GUI settings can currently clash with
(-dbcache, -par, -spendzeroconfchange, -signer, -upnp, -natpmp, -listen,
-server, -proxy, -proxy, -onion, -onion, -lang, and -prune).

Fix GUI startup crash reported by Rspigler in
https://github.com/bitcoin/bitcoin/issues/24457 that happens if

Subject: [PATCH 0127/1725] Handle query string when parsing data format

URLs may contain a query string (prefixed with '?') and this should be ignored when parsing
the data format.

To facilitate testing this functionality, ParseDataFormat has been made non-static.

Subject: [PATCH 0131/1725] qt: Remove network detection based on address in
 BIP21

This is some very ugly and brittle code that switches the global network
based on a provided address, remove it. I think in practice it's very
unlikely for testnet BIP21 payment URIs to be used, and if so it's for
testing so it's easy enough to manually copy it. Or to specify
`-testnet` explicitly.

There is already no case for `-regtest` or `-signet`.

Subject: [PATCH 0135/1725] ci: remove compiled-but-unused BDB from MSAN job

Self-compiled BDB was added to this job as opposed to using depends BDB
due to linking issues, however the compiled BDB is not actually used.
Remove it for now, given we don't actually lose any coverage (note that
BDB is also no used the MSAN fuzz job), and in future, we can use
depends BDB.

We don't use the deprecated headers now, and never should do in the

The headers themselves are just full of includes for the newer headers.

Subject: [PATCH 0138/1725] test: set segwit height back to 0 on regtest

This was changed in #22818 from 0 to 1. Since it changes
BLOCK_OPT_WIT of the genesis block, older versions of bitcoin
core would not read regtest directories created with newer versions
without a reindex.

Subject: [PATCH 0140/1725] [wallet] assert BnB internally calculated waste is
 the same as GetSelectionWaste()

These two implementations of waste calculation should never deviate.
Still keep the SelectCoinsBnB internal calculation because incremental
calculate-as-you-go is much more performant than calling
GetSelectionWaste() over and over again.

Subject: [PATCH 0149/1725] Add tests for addr destination rotation

Check that within 24h addr of a given node is forwarded
to the same peer(s), and then the destination is
rotated every 24h.

Subject: [PATCH 0150/1725] contrib: fix signet miner (sighash mismatch)

PSBT signing was changed to use SIGHASH_DEFAULT by default in #22514.
The signet miner script sets the sighash type of the created PSBT to
SIGHASH_ALL, hence this leads to a sighash mismatch when the
`walletprocesspsbt` RPC is called. Fix this by explicitly passing the
correct sighash type.

Note that the same change was needed in one of our functional tests,
see commit d3992669df826899a3de78a77a366dab46028026.

Reported by gruve-p.

Subject: [PATCH 0152/1725] refactor: Track BnB selection by index

This is a performance optimization - rather than track all visited values
in a bool vector, track the selected index in a vector. This results in a
complexity reduction of O(utxo_size) to O(selection_size).

Subject: [PATCH 0167/1725] Only load BlockMan in BlockMan member functions

This commit effectively splits the "load block index itself" logic from
"derive Chainstate variables from loaded block index" logic.

This means that BlockManager::LoadBlockIndex{,DB} will only load what's
relevant to the BlockManager.

I strongly recommend reviewing with the following git-diff flags:
  --color-moved=dimmed_zebra --color-moved-ws=allow-indentation-change

Subject: [PATCH 0178/1725] gui: restore Send for external signer

Before this change the send confirmation dialog would keep the Send option disabled. The Create Unsigned choice would actually send. This is potentially confusing.

With this change the Create Unsigned button will not attempt to sign and always produce a PSBT. The Send button will attempt to sign, and only return a PSBT if more signatures are needed.

When using an external signer, the Create Unsigned option only appears when PSBT controls are enabled in the wallet settings.

This commit maintains the pre-existing behavior of filling the PSBT (without signing) even when not using an external signer.

Closes #551

-Controlling dependencies
-------------------------
-Some dependencies are not needed in all configurations. The following are some factors that affect the dependency list.
-
-#### Options passed to `./configure`
-* MiniUPnPc is not needed with `--without-miniupnpc`.
-* libnatpmp is not needed with `--without-natpmp`.
-* Berkeley DB is not needed with `--disable-wallet` or `--without-bdb`.
-* SQLite is not needed with `--disable-wallet` or `--without-sqlite`.
-* Qt is not needed with `--without-gui`.
-* If the qrencode dependency is absent, QR support won't be added. To force an error when that happens, pass `--with-qrencode`.
-* If the systemtap dependency is absent, USDT support won't compiled in.
-* ZeroMQ is needed only with the `--with-zmq` option.
-
-#### Other
-* Not-Qt-bundled zlib is required to build the [DMG tool](../contrib/macdeploy/README.md#deterministic-macos-dmg-notes) from the libdmg-hfsplus project.

-To enable [descriptor wallets](https://github.com/bitcoin/bitcoin/blob/master/doc/descriptors.md), `sqlite` is required.
-Skip `berkeley-db@4` if you intend to *exclusively* use descriptor wallets.

Subject: [PATCH 0195/1725] script: expose getter for CScriptNum, add a
 BuildScript helper

Some prep work for Miniscript. BuildScript is an efficient way to build
Scripts in a generic manner (by concatenating OPs, data, and other
Scripts).

+/** This type encapsulates the miniscript type system properties.
+ *
+ * Every miniscript expression is one of 4 basic types, and additionally has
+ * a number of boolean type properties.
+ *
+ * The basic types are:
+ * - "B" Base:
+ *   - Takes its inputs from the top of the stack.
+ *   - When satisfied, pushes a nonzero value of up to 4 bytes onto the stack.
+ *   - When dissatisfied, pushes a 0 onto the stack.
+ *   - This is used for most expressions, and required for the top level one.
+ *   - For example: older(n) = <n> OP_CHECKSEQUENCEVERIFY.
+ * - "V" Verify:
+ *   - Takes its inputs from the top of the stack.
+ *   - When satisfactied, pushes nothing.
+ *   - Cannot be dissatisfied.
+ *   - This can be obtained by adding an OP_VERIFY to a B, modifying the last opcode
+ *     of a B to its -VERIFY version (only for OP_CHECKSIG, OP_CHECKSIGVERIFY
+ *     and OP_EQUAL), or by combining a V fragment under some conditions.
+ *   - For example vc:pk_k(key) = <key> OP_CHECKSIGVERIFY
+ * - "K" Key:
+ *   - Takes its inputs from the top of the stack.
+ *   - Becomes a B when followed by OP_CHECKSIG.
+ *   - Always pushes a public key onto the stack, for which a signature is to be
+ *     provided to satisfy the expression.
+ *   - For example pk_h(key) = OP_DUP OP_HASH160 <Hash160(key)> OP_EQUALVERIFY
+ * - "W" Wrapped:
+ *   - Takes its input from one below the top of the stack.
+ *   - When satisfied, pushes a nonzero value (like B) on top of the stack, or one below.
+ *   - When dissatisfied, pushes 0 op top of the stack or one below.
+ *   - Is always "OP_SWAP [B]" or "OP_TOALTSTACK [B] OP_FROMALTSTACK".
+ *   - For example sc:pk_k(key) = OP_SWAP <key> OP_CHECKSIG
+ *
+ * There a type properties that help reasoning about correctness:
+ * - "z" Zero-arg:
+ *   - Is known to always consume exactly 0 stack elements.
+ *   - For example after(n) = <n> OP_CHECKLOCKTIMEVERIFY
+ * - "o" One-arg:
+ *   - Is known to always consume exactly 1 stack element.
+ *   - Conflicts with property 'z'
+ *   - For example sha256(hash) = OP_SIZE 32 OP_EQUALVERIFY OP_SHA256 <hash> OP_EQUAL
+ * - "n" Nonzero:
+ *   - For every way this expression can be satisfied, a satisfaction exists that never needs
+ *     a zero top stack element.
+ *   - Conflicts with property 'z' and with type 'W'.
+ * - "d" Dissatisfiable:
+ *   - There is an easy way to construct a dissatisfaction for this expression.
+ *   - Conflicts with type 'V'.
+ * - "u" Unit:
+ *   - In case of satisfaction, an exact 1 is put on the stack (rather than just nonzero).
+ *   - Conflicts with type 'V'.
+ *
+ * Additional type properties help reasoning about nonmalleability:
+ * - "e" Expression:
+ *   - This implies property 'd', but the dissatisfaction is nonmalleable.
+ *   - This generally requires 'e' for all subexpressions which are invoked for that
+ *     dissatifsaction, and property 'f' for the unexecuted subexpressions in that case.
+ *   - Conflicts with type 'V'.
+ * - "f" Forced:
+ *   - Dissatisfactions (if any) for this expression always involve at least one signature.
+ *   - Is always true for type 'V'.
+ * - "s" Safe:
+ *   - Satisfactions for this expression always involve at least one signature.
+ * - "m" Nonmalleable:
+ *   - For every way this expression can be satisfied (which may be none),
+ *     a nonmalleable satisfaction exists.
+ *   - This generally requires 'm' for all subexpressions, and 'e' for all subexpressions
+ *     which are dissatisfied when satisfying the parent.
+ *
+ * One type property is an implementation detail:
+ * - "x" Expensive verify:
+ *   - Expressions with this property have a script whose last opcode is not EQUAL, CHECKSIG, or CHECKMULTISIG.
+ *   - Not having this property means that it can be converted to a V at no cost (by switching to the
+ *     -VERIFY version of the last opcode).
+ *
+ * Five more type properties for representing timelock information. Spend paths
+ * in miniscripts containing conflicting timelocks and heightlocks cannot be spent together.
+ * This helps users detect if miniscript does not match the semantic behaviour the
+ * user expects.
+ * - "g" Whether the branch contains a relative time timelock
+ * - "h" Whether the branch contains a relative height timelock
+ * - "i" Whether the branch contains an absolute time timelock
+ * - "j" Whether the branch contains an absolute height timelock
+ * - "k"
+ *   - Whether all satisfactions of this expression don't contain a mix of heightlock and timelock
+ *     of the same type.
+ *   - If the miniscript does not have the "k" property, the miniscript template will not match
+ *     the user expectation of the corresponding spending policy.
+ * For each of these properties the subset rule holds: an expression with properties X, Y, and Z, is also
+ * valid in places where an X, a Y, a Z, an XY, ... is expected.

+     *
+     * In more detail, it is invoked as node.TreeEvalMaybe<Result>(root, downfn, upfn):

+     * - downfn is a callable (State&, const Node&, size_t) -> State, which given a

+     *   child. It can modify the state. Children of a given node will have downfn()
+     *   called in order.
+     * - upfn is a callable (State&&, const Node&, Span<Result>) -> std::optional<Result>,
+     *   which given a node, its state, and a Span of the results of its children,
+     *   computes the result of the node. If std::nullopt is returned by upfn,

+
+*version* Release Notes Draft
+===============================
+
+Bitcoin Core version *version* is now available from:
+
+  <https://bitcoincore.org/bin/bitcoin-core-*version*/>
+
+This release includes new features, various bug fixes and performance
+improvements, as well as updated translations.
+
+Please report bugs using the issue tracker at GitHub:
+
+  <https://github.com/bitcoin/bitcoin/issues>
+
+To receive security and update notifications, please subscribe to:
+
+  <https://bitcoincore.org/en/list/announcements/join/>
+
+How to Upgrade
+==============
+
+If you are running an older version, shut it down. Wait until it has completely
+shut down (which might take a few minutes in some cases), then run the
+installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on Mac)
+or `bitcoind`/`bitcoin-qt` (on Linux).
+
+Upgrading directly from a version of Bitcoin Core that has reached its EOL is
+possible, but it might take some time if the data directory needs to be migrated. Old
+wallet versions of Bitcoin Core are generally supported.
+
+Compatibility
+==============
+
+Bitcoin Core is supported and extensively tested on operating systems
+using the Linux kernel, macOS 10.15+, and Windows 7 and newer.  Bitcoin
+Core should also work on most other Unix-like systems but is not as
+frequently tested on them.  It is not recommended to use Bitcoin Core on
+unsupported systems.

 #### After branch-off (on the major release branch)
 
 - Update the versions.
+- Create the draft, named "*version* Release Notes Draft", as a [collaborative wiki](https://github.com/bitcoin-core/bitcoin-devwiki/wiki/_new).
+- Clear the release notes: `cp doc/release-notes-empty-template.md doc/release-notes.md`
 - Create a pinned meta-issue for testing the release candidate (see [this issue](https://github.com/bitcoin/bitcoin/issues/17079) for an example) and provide a link to it in the release announcements where useful.
 - Translations on Transifex
     - Change the auto-update URL for the new major version's resource away from `master` and to the branch, e.g. `https://raw.githubusercontent.com/bitcoin/bitcoin/<branch>/src/qt/locale/bitcoin_en.xlf`. Do not forget this or it will keep tracking the translations on master instead, drifting away from the specific major release.
 
 #### Before final release
 
-- Merge the release notes from the wiki into the branch.
+- Merge the release notes from [the wiki](https://github.com/bitcoin-core/bitcoin-devwiki/wiki/) into the branch.
 - Ensure the "Needs release note" label is removed from all relevant pull requests and issues.
 
 #### Tagging a release (candidate)

As we change the constructor for COutput, it becomes somewhat dangerous
if there are default values.

Subject: [PATCH 0206/1725] wallet: Store whether a COutput is from the wallet

Instead of determining whether the containing transaction is from the
wallet dynamically as needed, just pass it in to COutput and store it.
The transaction ownership isn't going to change.

Subject: [PATCH 0211/1725] [net] Add CNode.m_relays_txs and
 CNode.m_bloom_filter_loaded

We'll move the transaction relay data into Peer in subsequent commits,
but the inbound eviction logic needs to know if the peer is relaying
txs and if the peer has loaded a bloom filter.

This is currently redundant information with m_tx_relay->fRelayTxes,
but when m_tx_relay is moved into net_processing, then we'll need these
separate fields in CNode.

Subject: [PATCH 0212/1725] [net processing] Move m_wtxid_relay to Peer

Also, remove cs_main guard from m_wtxid_relay_peers and make it atomic.
This should be fine since we don't need m_wtxid_relay_peers to be
synchronized with m_wtxid_relay exactly at all times.

After this change, RelayTransaction no longer requires cs_main.

Subject: [PATCH 0222/1725] Bugfix: configure: Quote SUPPRESS_WARNINGS
 sufficiently to preserve brackets

The regex includes [/ ] which is supposed to match either a forward slash or a

scenario where it is the final parameter in the flag string.

+# CJDNS support in Bitcoin Core
+
+It is possible to run Bitcoin Core over CJDNS, an encrypted IPv6 network that
+uses public-key cryptography for address allocation and a distributed hash table
+for routing.
+
+## What is CJDNS?
+
+CJDNS is like a distributed, shared VPN with multiple entry points where every
+participant can reach any other participant. All participants use addresses from
+the `fc00::/8` network (reserved IPv6 range). Installation and configuration is
+done outside of Bitcoin Core, similarly to a VPN (either in the host/OS or on
+the network router).
+
+Compared to IPv4/IPv6, CJDNS provides end-to-end encryption and protects nodes
+from traffic analysis and filtering.
+
+Used with Tor and I2P, CJDNS is a complementary option that can enhance network
+redundancy and robustness for both the Bitcoin network and individual nodes.
+
+Each network has different characteristics. For instance, Tor is widely used but
+somewhat centralized. I2P connections have a source address and I2P is slow.
+CJDNS is fast but does not hide the sender and the recipient from intermediate
+routers.
+
+## Installing CJDNS and connecting to the network
+
+To install and set up CJDNS, follow the instructions at
+https://github.com/cjdelisle/cjdns#cjdns.
+
+Don't skip steps
+["2. Find a friend"](https://github.com/cjdelisle/cjdns#2-find-a-friend) and
+["3. Connect your node to your friend's
+node"](https://github.com/cjdelisle/cjdns#3-connect-your-node-to-your-friends-node).
+You need to be connected to the CJDNS network before it will work with your
+Bitcoin Core node.
+
+Typically, CJDNS might be launched from its directory with
+`sudo ./cjdroute < cjdroute.conf` and it sheds permissions after setting up the
+[TUN](https://en.wikipedia.org/wiki/TUN/TAP) interface. You may also [launch it as an
+unprivileged user](https://github.com/cjdelisle/cjdns/blob/master/doc/non-root-user.md)
+with some additional setup.
+
+The network connection can be checked by running `./tools/peerStats` from the
+CJDNS directory.
+
+## Run Bitcoin Core with CJDNS
+
+Once you are connected to the CJDNS network, the following Bitcoin Core
+configuration option makes CJDNS peers automatically reachable:
+
+```
+-cjdnsreachable
+```
+
+When enabled, this option tells Bitcoin Core that it is running in an
+environment where a connection to an `fc00::/8` address will be to the CJDNS
+network instead of to an [RFC4193](https://datatracker.ietf.org/doc/html/rfc4193)
+IPv6 local network. This helps Bitcoin Core perform better address management:
+  - Your node can consider incoming `fc00::/8` connections to be from the CJDNS
+    network rather than from an IPv6 private one.
+  - If one of your node's local addresses is `fc00::/8`, then it can choose to
+    gossip that address to peers.
+
+## Additional configuration options related to CJDNS
+
+```
+-onlynet=cjdns
+```
+
+Make automatic outbound connections only to CJDNS addresses. Inbound and manual
+connections are not affected by this option. It can be specified multiple times
+to allow multiple networks, e.g. onlynet=cjdns, onlynet=i2p, onlynet=onion.
+
+CJDNS support was added to Bitcoin Core in version 23.0 and there may be fewer
+CJDNS peers than Tor or IP ones. You can use `bitcoin-cli -addrinfo` to see the
+number of CJDNS addresses known to your node.
+
+In general, a node can be run with both an onion service and CJDNS (or any/all
+of IPv4/IPv6/onion/I2P/CJDNS), which can provide a potential fallback if one of
+the networks has issues. There are a number of ways to configure this; see
+[doc/tor.md](https://github.com/bitcoin/bitcoin/blob/master/doc/tor.md) for
+details.
+
+## CJDNS-related information in Bitcoin Core
+
+There are several ways to see your CJDNS address in Bitcoin Core:
+- in the "Local addresses" output of CLI `-netinfo`
+- in the "localaddresses" output of RPC `getnetworkinfo`
+
+To see which CJDNS peers your node is connected to, use `bitcoin-cli -netinfo 4`
+or the `getpeerinfo` RPC (i.e. `bitcoin-cli getpeerinfo`).
+
+To see which CJDNS addresses your node knows, use the `getnodeaddresses 0 cjdns`
+RPC.

 ## Preparation
 
 ### 1. Install Required Dependencies
-Install the required dependencies the usual way you [install software on FreeBSD](https://www.freebsd.org/doc/en/books/handbook/ports.html) - either with `pkg` or via the Ports collection. The example commands below use `pkg` which is usually run as `root` or via `sudo`. If you want to use `sudo`, and you haven't set it up: [use this guide](http://www.freebsdwiki.net/index.php/Sudo%2C_configuring) to setup `sudo` access on FreeBSD.
+Run the following as root to install the base dependencies for building.
 
 ```bash
 pkg install autoconf automake boost-libs git gmake libevent libtool pkgconf

Subject: [PATCH 0238/1725] options: flip listenonion to false if not listening

If the user has unchecked "Allow incoming connections" in
`Settings->Options...->Network` then `fListen=false` is saved in
`~/.config/Bitcoin/Bitcoin-Qt.conf`. This flips `-listen` to `false`
during startup, but leaves `-listenonion` to `true`.

This flipping of `-listen` is done in `OptionsModel::Init()` after
`InitParameterInteraction()` has been executed which would have flipped
`-listenonion`, should it have seen `-listen` being `false`
(this is a difference between `bitcoind` and `bitcoin-qt`).

Fixes: https://github.com/bitcoin-core/gui/issues/567

Every system we support has 2.4.6 available, except for OpenBSD, which
currently ships with 2.4.2 (released 2011). For now, set our minimum
required version to that.

After a 7 year hitus, 2.4.7 has also very recently been released:
https://savannah.gnu.org/forum/forum.php?forum_id=10139.

-This explicitly enables the GUI and disables legacy wallet support. If `qt5` is not installed, this will throw an error. If `sqlite3` is installed then descriptor wallet functionality will be built. If `sqlite3` is not installed, then wallet functionality will be disabled.
-```bash
-./autogen.sh
-./configure --without-bdb --with-gui=yes MAKE=gmake
-```
 ##### No Wallet or GUI
 ``` bash
 ./autogen.sh

Subject: [PATCH 0242/1725] wallet: Replace CWalletTx in COutput with COutPoint
 and CTxOut

Instead of having a pointer to the CWalletTx in COutput, we can just
store the COutPoint and the CTxOut as those are the only things we need
from the CWalletTx. Other things CWalletTx used to provide were time and
fIsFromMe but these are also being stored by COutput.

Subject: [PATCH 0248/1725] coinselection: Remove COutput operators == and !=

These operators are used only by the tests in std::mismatch. As
std::mismatch can take a binary predicate, we can use a lambda that
achieves the same instead.

Subject: [PATCH 0256/1725] Add CSerializedNetMsg::Copy() helper

This makes code that uses the helper less verbose.

Moreover, this makes net_processing C++20 compliant. Otherwise, it would
lead to a compile error (see below). C++20 disables aggregate
initialization when any constructor is declared. See
http://open-std.org/JTC1/SC22/WG21/docs/papers/2018/p1008r1.pdf

net_processing.cpp:1627:42: error: no matching constructor for initialization of 'CSerializedNetMsg'

Subject: [PATCH 0265/1725] tests: Calculate input weight more accurately

The external input test with specifying input weight would make a
pessimistic estimate of the input weight. However this would result in a
test failure as it is sometimes too pessimistic when an ECDSA signature
ends up being smaller than usual. To correct this, we can calculate the
input weight more accurately.

+Coding Style (C++ named arguments)
+------------------------------
+
+When passing named arguments, use a format that clang-tidy understands. The
+argument names can otherwise not be verified by clang-tidy.
+
+For example:
+
+```c++
+void function(Addrman& addrman, bool clear);
+
+int main()
+{
+    function(g_addrman, /*clear=*/false);
+}
+```
+
+### Running clang-tidy
+
+To run clang-tidy on Ubuntu/Debian, install the dependencies:
+
+```sh
+apt install clang-tidy bear clang
+```
+
+Then, pass clang as compiler to configure, and use bear to produce the `compile_commands.json`:
+
+```sh
+./autogen.sh && ./configure CC=clang CXX=clang++
+make clean && bear make -j $(nproc)     # For bear 2.x
+make clean && bear -- make -j $(nproc)  # For bear 3.x
+```
+
+To run clang-tidy on all source files:
+
+```sh
+( cd ./src/ && run-clang-tidy  -j $(nproc) )
+```
+
+To run clang-tidy on the changed source lines:
+
+```sh
+git diff | ( cd ./src/ && clang-tidy-diff -p2 -j $(nproc) )
+```
+

Subject: [PATCH 0282/1725] refactor: remove unused boost header include in
 bitcoin-util.cpp

This header was included since the introduction of bitcoin-util in
commit 13762bcc9618138dd28b53c2031defdc9d762d26, but boost was
actually never used (see `git log -S boost ./src/bitcoin-util.cpp`).

Subject: [PATCH 0292/1725] net_processing: move CNode data access out of lock

CNode::m_relays_tx and CNode::m_bloom_filter_loaded access don't require
the Peer::TxRelay::m_bloom_filter_mutex lock, so move them out of the
lock scope.

See https://github.com/bitcoin/bitcoin/pull/21160#discussion_r736785417
and https://github.com/bitcoin/bitcoin/pull/21160#discussion_r736785662.

Subject: [PATCH 0298/1725] doc: update OpenBSD build docs for 7.0

Removes redundant notes for setting CC & CXX now that Clang is well and
truly the base compiler.
Cleans up the wallet docs, i.e #23446.
Make the notes more similar to FreeBSD.

-OpenBSD build guide
-======================
-(updated for OpenBSD 6.9)
+# OpenBSD Build Guide
 
-This guide describes how to build bitcoind, bitcoin-qt, and command-line utilities on OpenBSD.
+**Updated for OpenBSD [7.0](https://www.openbsd.org/70.html)**
 
-Preparation
--------------
+This guide describes how to build bitcoind, command-line utilities, and GUI on OpenBSD.
 
-Run the following as root to install the base dependencies for building:
+## Preparation
+
+### 1. Install Required Dependencies
+Run the following as root to install the base dependencies for building.
 
 ```bash
-pkg_add git gmake libevent libtool boost
-pkg_add qt5 # (optional for enabling the GUI)
-pkg_add autoconf # (select highest version, e.g. 2.69)
-pkg_add automake # (select highest version, e.g. 1.16)
-pkg_add python # (select highest version, e.g. 3.8)
-pkg_add bash
+pkg_add bash git gmake libevent libtool boost
+# Select the newest version of the follow packages:
+pkg_add autoconf automake python
+```
 
+See [dependencies.md](dependencies.md) for a complete overview.
+
+### 2. Clone Bitcoin Repo
+Clone the Bitcoin Core repository to a directory. All build scripts and commands will run from this directory.
+``` bash
 git clone https://github.com/bitcoin/bitcoin.git
 ```
 
-See [dependencies.md](dependencies.md) for a complete overview.
+### 3. Install Optional Dependencies
 
-**Important**: From OpenBSD 6.2 onwards a C++11-supporting clang compiler is
-part of the base image, and while building it is necessary to make sure that
-this compiler is used and not ancient g++ 4.2.1. This is done by appending
-`CC=cc CXX=c++` to configuration commands. Mixing different compilers within
-the same executable will result in errors.
+#### Wallet Dependencies
 
-### Building BerkeleyDB
+It is not necessary to build wallet functionality to run either `bitcoind` or `bitcoin-qt`.
+
+###### Descriptor Wallet Support
+
+`sqlite3` is required to support [descriptor wallets](descriptors.md).
+
+``` bash
+pkg_add install sqlite3
+```
 
-BerkeleyDB is only necessary for the wallet functionality. To skip this, pass
-`--disable-wallet` to `./configure` and skip to the next section.
+###### Legacy Wallet Support
+BerkeleyDB is only required to support legacy wallets.
 
 It is recommended to use Berkeley DB 4.8. You cannot use the BerkeleyDB library
-from ports, for the same reason as boost above (g++/libstd++ incompatibility).
-If you have to build it yourself, you can use [the installation script included
-in contrib/](/contrib/install_db4.sh) like so:
+from ports. However you can build it yourself, [using the installation script included in contrib/](/contrib/install_db4.sh), like so, from the root of the repository.
 
 ```bash
-./contrib/install_db4.sh `pwd` CC=cc CXX=c++
+./contrib/install_db4.sh `pwd`
 ```
 
-from the root of the repository. Then set `BDB_PREFIX` for the next section:
+Then set `BDB_PREFIX`:
 
 ```bash
 export BDB_PREFIX="$PWD/db4"
 ```
 
-### Building Bitcoin Core
+#### GUI Dependencies
+###### Qt5
+
+Bitcoin Core includes a GUI built with the cross-platform Qt Framework. To compile the GUI, Qt 5 is required.
+
+```bash
+pkg_add qt5
+```
+
+## Building Bitcoin Core
 
 **Important**: Use `gmake` (the non-GNU `make` will exit with an error).
 
 Preparation:
 ```bash
 
-# Replace this with the autoconf version that you installed. Include only
-# the major and minor parts of the version: use "2.69" for "autoconf-2.69p2".
-export AUTOCONF_VERSION=2.69
-
-# Replace this with the automake version that you installed. Include only
-# the major and minor parts of the version: use "1.16" for "automake-1.16.1".
+# Adapt the following for the version you installed (major.minor only):
+export AUTOCONF_VERSION=2.71
 export AUTOMAKE_VERSION=1.16
 
 ./autogen.sh
 ```
-Make sure `BDB_PREFIX` is set to the appropriate path from the above steps.
+
+### 1. Configuration
 
 Note that building with external signer support currently fails on OpenBSD,
 hence you have to explicitly disable it by passing the parameter
-`--disable-external-signer` to the configure script.
-(Background: the feature requires the header-only library boost::process, which
-is available on OpenBSD 6.9 via Boost 1.72.0, but contains certain system calls
-and preprocessor defines like `waitid()` and `WEXITED` that are not available.)
+`--disable-external-signer` to the configure script. The feature requires the
+header-only library boost::process, which is available on OpenBSD, but contains
+certain system calls and preprocessor defines like `waitid()` and `WEXITED` that
+are not available.
 
-To configure with wallet:
-```bash
-./configure --with-gui=no --disable-external-signer CC=cc CXX=c++ \
-    BDB_LIBS="-L${BDB_PREFIX}/lib -ldb_cxx-4.8" \
-    BDB_CFLAGS="-I${BDB_PREFIX}/include" \
-    MAKE=gmake
-```
+There are many ways to configure Bitcoin Core, here are a few common examples:
+
+##### Descriptor Wallet and GUI:
+This enables the GUI and descriptor wallet support, assuming `sqlite` and `qt5` are installed.
 
-To configure without wallet:
 ```bash
-./configure --disable-wallet --with-gui=no --disable-external-signer CC=cc CXX=c++ MAKE=gmake
+./configure --disable-external-signer MAKE=gmake
 ```
 
-To configure with GUI:
+##### Descriptor & Legacy Wallet. No GUI:
+This enables support for both wallet types and disables the GUI:
+
 ```bash
-./configure --with-gui=yes --disable-external-signer CC=cc CXX=c++ \
+./configure --disable-external-signer --with-gui=no \
     BDB_LIBS="-L${BDB_PREFIX}/lib -ldb_cxx-4.8" \
     BDB_CFLAGS="-I${BDB_PREFIX}/include" \
     MAKE=gmake
 ```
 
-Build and run the tests:
+### 2. Compile
+**Important**: Use `gmake` (the non-GNU `make` will exit with an error).
+
 ```bash
-gmake # use "-j N" here for N parallel jobs
-gmake check
+gmake # use "-j N" for N parallel jobs
+gmake check # Run tests if Python 3 is available
 ```
 
-Resource limits
--------------------
+## Resource limits
 
 If the build runs into out-of-memory errors, the instructions in this section
 might help.
 
 The standard ulimit restrictions in OpenBSD are very strict:
-
-    data(kbytes)         1572864
+```bash
+data(kbytes)         1572864
+```
 
 This is, unfortunately, in some cases not enough to compile some `.cpp` files in the project,
 (see issue [#6658](https://github.com/bitcoin/bitcoin/issues/6658)).
 If your user is in the `staff` group the limit can be raised with:
-
-    ulimit -d 3000000
-
+```bash
+ulimit -d 3000000
+```
 The change will only affect the current shell and processes spawned by it. To
 make the change system-wide, change `datasize-cur` and `datasize-max` in
 `/etc/login.conf`, and reboot.

Subject: [PATCH 0307/1725] =?UTF-8?q?Add=20sendall=20RPC=20n=C3=A9e=20swee?=
 =?UTF-8?q?p?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

_Motivation_
Currently, the wallet uses a fSubtractFeeAmount (SFFO) flag on the
recipients objects for all forms of sending calls. According to the
commit discussion, this flag was chiefly introduced to permit sweeping
without manually calculating the fees of transactions. However, the flag
leads to unintuitive behavior and makes it more complicated to test
many wallet RPCs exhaustively. We proposed to introduce a dedicated
`sendall` RPC with the intention to cover this functionality.

Since the proposal, it was discovered in further discussion that our
proposed `sendall` rpc and SFFO have subtly different scopes of
operation.
• sendall:
  Use _specific UTXOs_ to pay a destination the remainder after fees.
• SFFO:
  Use a _specific budget_ to pay an address the remainder after fees.

While `sendall` will simplify cases of spending from specific UTXOs,
emptying a wallet, or burning dust, we realized that there are some
cases in which SFFO is used to pay other parties from a limited budget,
which can often lead to the creation of change outputs. This cannot be
easily replicated using `sendall` as it would require manual computation
of the appropriate change amount.

As such, sendall cannot replace all uses of SFFO, but it still has a
different use case and will aid in simplifying some wallet calls and
numerous wallet tests.

_Sendall call details_
The proposed sendall call builds a transaction from a specific subset of
the wallet's UTXO pool (by default all of them) and assigns the funds to
one or more receivers. Receivers can either be specified with a specific
amount or receive an equal share of the remaining unassigned funds. At
least one recipient must be provided without assigned amount to collect
the remainder. The `sendall` call will never create change. The call has
a `send_max` option that changes the default behavior of spending all
UTXOs ("no UTXO left behind"), to maximizing the output amount of the
transaction by skipping uneconomic UTXOs. The `send_max` option is
incompatible with providing a specific set of inputs.

+New RPCs
+--------
+
+- The `sendall` RPC spends specific UTXOs to one or more recipients
+  without creating change. By default, the `sendall` RPC will spend
+  every UTXO in the wallet. `sendall` is useful to empty wallets or to
+  create a changeless payment from select UTXOs. When creating a payment
+  from a specific amount for which the recipient incurs the transaction
+  fee, continue to use the `subtractfeefromamount` option via the
+  `send`, `sendtoaddress`, or `sendmany` RPCs. (#24118)

Subject: [PATCH 0309/1725] doc: Speed up functional test runs using ramdisk

Using a ramdisk for the functional tests can give worthwhile speed-ups
for developers and reviewers.

Add notes to test/README.md on how to setup, use and erase a ramdisk on
Linux.

 The individual tests and the test_runner harness have many command-line
 options. Run `test/functional/test_runner.py -h` to see them all.
 
+#### Speed up test runs with a ramdisk
+
+If you have available RAM on your system you can create a ramdisk to use as the `cache` and `tmp` directories for the functional tests in order to speed them up.
+Speed-up amount varies on each system (and according to your ram speed and other variables), but a 2-3x speed-up is not uncommon.
+
+To create a 4GB ramdisk on Linux at `/mnt/tmp/`:
+
+```bash
+sudo mkdir -p /mnt/tmp
+sudo mount -t tmpfs -o size=4g tmpfs /mnt/tmp/
+```
+
+Configure the size of the ramdisk using the `size=` option.
+The size of the ramdisk needed is relative to the number of concurrent jobs the test suite runs.
+For example running the test suite with `--jobs=100` might need a 4GB ramdisk, but running with `--jobs=32` will only need a 2.5GB ramdisk.
+
+To use, run the test suite specifying the ramdisk as the `cachedir` and `tmpdir`:
+
+```bash
+test/functional/test_runner.py --cachedir=/mnt/tmp/cache --tmpdir=/mnt/tmp
+```
+
+Once finished with the tests and the disk, and to free the ram, simply unmount the disk:
+
+```bash
+sudo umount /mnt/tmp
+```
+

Subject: [PATCH 0316/1725] rpc: Fix documentation assertion for
 `getrawtransaction`

When `getrawtransaction` is successfully used on a coinbase transaction,
there is an assertion error. This is very unlikely but happens in the
test in #24358.

This does the following:

- Add missing "coinbase" documentation.

- Synchronize documentation between `getrawtransaction` and
  `decoderawtransaction`, the two users of `TxToUniv` that have detailed
  documentation. `decodepsbt` also uses it but fortunately elides this block.

- Change "vout[].amount" to `STR_AMOUNT` for consistency.

- Add maintainer comment to keep the two places synchronized. It might
  be possible to get smarter with deduplication, but there are some
  extra fields that prevent the obvious way.

Subject: [PATCH 0322/1725] wallet: Postpone NotifyWalletLoaded() for encrypted
 wallets

Too early NotifyWalletLoaded() call in CWallet::Create() results the
notification goes before DescriptorScriptPubKeyMans were created and
added to an encrypted wallet.

Subject: [PATCH 0326/1725] build: patch around qt duplicate symbol issue

This is currently causing the same failure in two different PRs:
```bash
duplicate symbol 'lcQpaFonts()' in:
    /tmp/cirrus-ci-build/depends/x86_64-apple-darwin/lib/libQt5ThemeSupport.a(qgenericunixthemes.o)
    /tmp/cirrus-ci-build/depends/x86_64-apple-darwin/lib/libQt5FontDatabaseSupport.a(qfontengine_coretext.o)
ld: 1 duplicate symbol for architecture x86_64
```

```bash
x86_64-apple-darwin-ld: error: duplicate symbol: __Z10lcQpaFontsv
>>> defined in /tmp/cirrus-ci-build/depends/x86_64-apple-darwin/lib/libQt5ThemeSupport.a(qgenericunixthemes.o)
>>> defined in /tmp/cirrus-ci-build/depends/x86_64-apple-darwin/lib/libQt5FontDatabaseSupport.a(qfontengine_coretext.o)

Subject: [PATCH 0332/1725] guix: fix vmov alignment issues with gcc 10.3.0 &
 mingw-w64

This introduces a patch to our GCC (10.3.0) mingw-w64 compiler, in Guix, to make
it avoid using aligned vmov instructions. This works around a longstanding issue
in GCC, https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54412, which was recently
discovered to be causing issues, see #24726.

Note that distros like Debian are also patching around this issue, and that is
where this patch comes from. This would also explain why we haven't run into this
problem earlier, in development builds. See:
https://salsa.debian.org/mingw-w64-team/gcc-mingw-w64/-/blob/master/debian/patches/vmov-alignment.patch.

Fixes #24726.
Alternative to #24727.

      a competing package or transaction with a mutated witness, even though the two
      same-txid-different-witness transactions are conflicting and cannot replace each other, the
      honest package should still be considered for acceptance.
+
+### Package Fees and Feerate
+
+*Package Feerate* is the total modified fees (base fees + any fee delta from
+`prioritisetransaction`) divided by the total virtual size of all transactions in the package.
+If any transactions in the package are already in the mempool, they are not submitted again
+("deduplicated") and are thus excluded from this calculation.
+
+To meet the two feerate requirements of a mempool, i.e., the pre-configured minimum relay feerate
+(`minRelayTxFee`) and the dynamic mempool minimum feerate, the total package feerate is used instead
+of the individual feerate. The individual transactions are allowed to be below the feerate
+requirements if the package meets the feerate requirements. For example, the parent(s) in the
+package can pay no fees but be paid for by the child.
+
+*Rationale*: This can be thought of as "CPFP within a package," solving the issue of a parent not
+meeting minimum fees on its own. This would allow contracting applications to adjust their fees at
+broadcast time instead of overshooting or risking becoming stuck or pinned.
+
+*Rationale*: It would be incorrect to use the fees of transactions that are already in the mempool, as
+we do not want a transaction's fees to be double-counted.
+
+Implementation Note: Transactions within a package are always validated individually first, and
+package validation is used for the transactions that failed. Since package feerate is only
+calculated using transactions that are not in the mempool, this implementation detail affects the
+outcome of package validation.
+
+*Rationale*: Packages are intended for incentive-compatible fee-bumping: transaction B is a
+"legitimate" fee-bump for transaction A only if B is a descendant of A and has a *higher* feerate
+than A. We want to prevent "parents pay for children" behavior; fees of parents should not help
+their children, since the parents can be mined without the child.  More generally, if transaction A
+is not needed in order for transaction B to be mined, A's fees cannot help B. In a
+child-with-parents package, simply excluding any parent transactions that meet feerate requirements
+individually is sufficient to ensure this.
+
+*Rationale*: We must not allow a low-feerate child to prevent its parent from being accepted; fees
+of children should not negatively impact their parents, since they are not necessary for the parents
+to be mined. More generally, if transaction B is not needed in order for transaction A to be mined,
+B's fees cannot harm A. In a child-with-parents package, simply validating parents individually
+first is sufficient to ensure this.
+
+*Rationale*: As a principle, we want to avoid accidentally restricting policy in order to be
+backward-compatible for users and applications that rely on p2p transaction relay. Concretely,
+package validation should not prevent the acceptance of a transaction that would otherwise be
+policy-valid on its own. By always accepting a transaction that passes individual validation before
+trying package validation, we prevent any unintentional restriction of policy.

Subject: [PATCH 0342/1725] build: don't use Boost multi_index serialization

We don't use the serialilzation or archiving facilities of multi_index.
So globally disable support, which gives a minor improvement in build
time, i.e less preprocessing work.

See: https://www.boost.org/doc/libs/1_78_0/libs/multi_index/doc/tutorial/creation.html

The removed code was intended to catch issues with event_enable_debug_logging which was not available prior to libevent 2.1.1. This is not necessary since the minimum libevent version was bumped to 2.1.8.

Subject: [PATCH 0350/1725] build: specify cmake build dir for multiprocess
 depends build

When no build dir is specified, cmake will warn:
```bash
Preprocessing libmultiprocess...
Configuring libmultiprocess...
CMake Warning:
  No source or binary directory provided.  Both will be assumed to be the
  same as the current working directory, but note that this warning will
  become a fatal error in future CMake releases.
```

It's unclear if this will actually ever become an error, but it's also easy
enough to just supply the directory, and save this maybe breaking in
future.

Subject: [PATCH 0351/1725] ci: use DWARF-4 for Valgrind CI job

clang-14 defaults to using DWARF-5, which breaks vlagrinds (3.18) ability
to parse debug info. Valgrind claims to support DWARF-5 from version
3.18 onwards, but maybe that only works when building with GCC.

Explicitly use DWARF-4 for now. Note that from 11.0 GCC also defaults to
using DWARF-5.

Subject: [PATCH 0358/1725] consensus/params: set default values for
 BIP9Deployment

While chainparams should explicilty set values for each possible
entry in vDeployments, in the past that has been missed resulting
in potential undefined behaviour due to accessing unitinitialized
data. Reduce the severity of future bugs of that nature by providing
benign default values. Adds a unit test to alert if the default value
is not overwritten for the real chains (NEVER_ACTIVE/NEVER_ACTIVE rather
than NEVER_ACTIVE/NO_TIMEOUT).

+### DEBUG_LOCKCONTENTION
+
+Defining `DEBUG_LOCKCONTENTION` adds a "lock" logging category to the logging
+RPC that, when enabled, logs the location and duration of each lock contention
+to the `debug.log` file.
+
+To enable it, run configure with `-DDEBUG_LOCKCONTENTION` added to your
+CPPFLAGS, e.g. `CPPFLAGS="-DDEBUG_LOCKCONTENTION"`, then build and run bitcoind.
+
+You can then use the `-debug=lock` configuration option at bitcoind startup or
+`bitcoin-cli logging '["lock"]'` at runtime to turn on lock contention logging.
+It can be toggled off again with `bitcoin-cli logging [] '["lock"]'`.

Subject: [PATCH 0371/1725] Update /<count>/ endpoints to use a '?count=' query
 parameter instead

In most RESTful APIs, path parameters are used to represent resources, and
query parameters are used to control how these resources are being filtered/sorted/...

The old /<count>/ functionality is kept alive to maintain backwards compatibility,
but new paths with query parameters are introduced and documented as the default
interface so future API methods don't break consistency by using query parameters.

+Notable changes
+===============
+
+Updated REST APIs
+-----------------
+
+- The `/headers/` and `/blockfilterheaders/` endpoints have been updated to use
+  a query parameter instead of path parameter to specify the result count. The
+  count parameter is now optional, and defaults to 5 for both endpoints. The old
+  endpoints are still functional, and have no documented behaviour change.
+
+  For `/headers`, use
+  `GET /rest/headers/<BLOCK-HASH>.<bin|hex|json>?count=<COUNT=5>`
+  instead of
+  `GET /rest/headers/<COUNT>/<BLOCK-HASH>.<bin|hex|json>` (deprecated)
+
+  For `/blockfilterheaders/`, use
+  `GET /rest/blockfilterheaders/<FILTERTYPE>/<BLOCK-HASH>.<bin|hex|json>?count=<COUNT=5>`
+  instead of
+  `GET /rest/blockfilterheaders/<FILTERTYPE>/<COUNT>/<BLOCK-HASH>.<bin|hex|json>` (deprecated)
+
+  (#24098)

Subject: [PATCH 0381/1725] [validation] try individual validation before
 package validation

This avoids "parents pay for children" and "siblings pay for siblings"
behavior, since package feerate is calculated with totals and is
topology-unaware.

It also ensures that package validation never causes us to reject a
transaction that we would have otherwise accepted in single-tx
validation.

Subject: [PATCH 0383/1725] [validation] don't package validate if not policy
 or missing inputs

Package validation policy only differs from individual policy in its
evaluation of feerate. Minimize DoS surface; don't validate all over
again if we know the result will be the same.

+
+    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
+    LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
+    ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
+    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
+    REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
+    PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
+    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
+    HEREUNDER.
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+  i. the right to reproduce, adapt, distribute, perform, display,
+     communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+     likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+     subject to the limitations in paragraph 4(a), below;
+  v. rights protecting the extraction, dissemination, use and reuse of data
+     in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+     European Parliament and of the Council of 11 March 1996 on the legal
+     protection of databases, and under any national implementation
+     thereof, including any amended or successor version of such
+     directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+     world based on applicable law or treaty, and any national
+     implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the
+maximum duration provided by applicable law or treaty (including future
+time extensions), (iii) in any current or future medium and for any number
+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's
+express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
+    surrendered, licensed or otherwise affected by this document.
+ b. Affirmer offers the Work as-is and makes no representations or
+    warranties of any kind concerning the Work, express, implied,
+    statutory or otherwise, including without limitation warranties of
+    title, merchantability, fitness for a particular purpose, non
+    infringement, or the absence of latent or other defects, accuracy, or
+    the present or absence of errors, whether or not discoverable, all to
+    the greatest extent permissible under applicable law.
+ c. Affirmer disclaims responsibility for clearing rights of other persons
+    that may apply to the Work or any use thereof, including without
+    limitation any person's Copyright and Related Rights in the Work.
+    Further, Affirmer disclaims responsibility for obtaining any necessary
+    consents, permissions or other rights required for any use of the
+    Work.
+ d. Affirmer understands and acknowledges that Creative Commons is not a
+    party to this document and has no duty or obligation with respect to
+    this CC0 or use of the Work.

+/** SHA256 counter tests
+
+The tests verify that the SHA256 counter doesn't wrap around at message length
+2^i bytes for i = 20, ..., 33. This wide range aims at being independent of the
+implementation of the counter and it catches multiple natural 32-bit overflows
+(e.g., counting bits, counting bytes, counting blocks, ...).
+
+The test vectors have been generated using following Python script which relies
+on https://github.com/cloudtools/sha256/ (v0.3 on Python v3.10.2).

Changes the color of skipped functional tests to the default text color of the terminal. This will make skipped tests easy to read on the majority of background colors rather than the original grey color (hard to read on dark backgrounds) and the proposed yellow change (hard to read on white backgrounds)

 framework

The path is stored in `self.options.bitcoinutil`, points to
`src/bitcoin-util` by default and can be overrided with the
`BITCOINUTIL` environment variable.

Subject: [PATCH 0427/1725] refactor: introduce single-separator split helper
 `SplitString`

This helper uses spanparsing::Split internally and enables to replace
all calls to boost::split where only a single separator is passed.

Subject: [PATCH 0430/1725] build: Don't add unrelated libs to LIBTEST_*

This was used to, in effect, manually emulate --start-group/--end-group.
However, we can just order the libraries correctly and avoid specifying
libraries multiple times on the link line.

Note: lld (not ld.bfd) knows how to resolve out-of-order references and
      doesn't seem to need the reodering

Subject: [PATCH 0432/1725] init: Prevent -noproxy and -proxy=0 settings from
 interacting with other settings

Prevent -noproxy and -proxy=0 settings from interacting with -listen, -upnp,
and -natpmp settings.

These settings started being handled inconsistently in the `AppInitMain` and
`InitParameterInteraction` functions starting in commit
baf05075fae2cc2625a2a74b35cc66902f3cbfa3 from #6272:

https://github.com/bitcoin/bitcoin/blob/baf05075fae2cc2625a2a74b35cc66902f3cbfa3/src/init.cpp#L990-L991
https://github.com/bitcoin/bitcoin/blob/baf05075fae2cc2625a2a74b35cc66902f3cbfa3/src/init.cpp#L687

This commit changes both functions to handle proxy arguments the same way so
there are not side effects from specifying a proxy=0 setting.

Subject: [PATCH 0433/1725] validation: Load pindexBestHeader in ChainMan

Now BlockManager::LoadBlockIndex() will ACTUALLY only load BlockMan
members.

[META] In a later commit, pindexBestHeader will be moved to ChainMan as
       a member

-----

Code Reviewer Notes

Call graph of relevant functions:

ChainstateManager::LoadBlockIndex() <-- Moved to
    calls BlockManager::LoadBlockIndexDB()
        which calls BlockManager::LoadBlockIndex() <-- Moved from

There is only one call to each of inner functions, meaning that no
behavior is changing.

Subject: [PATCH 0434/1725] guix: fix GCC 10.3.0 + mingw-w64 setjmp/longjmp
 issues

This commit backports a patch to the GCC 10.3.0 we build for Windows
cross-compilation in Guix. The commit has been backported to the GCC
releases/gcc-10 branch, but hasn't yet made it into a release.

The patch corrects a regression from an earlier GCC commit, see:
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=357c4350680bf29f0c7a115424e3da11c53b5582
and
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=074226d5aa86cd3de517014acfe34c7f69a2ccc7,
related to the way newer versions of mingw-w64 implement setjmp/longjmp.

Ultimately this was causing a crash for us when Windows users were
viewing the network traffic tab inside the GUI. After some period, long
enough that a buffer would need reallocating, a call into FreeTypes
gray_record_cell() would result in a call to ft_longjmp (longjmp), which
would then trigger a crash.

Fixes: https://github.com/bitcoin-core/gui/issues/582.

+    Fix PR target/100402
+    
+    This is a regression for 64-bit Windows present from mainline down to the 9
+    branch and introduced by the fix for PR target/99234.  Again SEH, but with
+    a twist related to the way MinGW implements setjmp/longjmp, which turns out
+    to be piggybacked on SEH with recent versions of MinGW, i.e. the longjmp
+    performs a bona-fide unwinding of the stack, because it calls RtlUnwindEx
+    with the second argument initially passed to setjmp, which is the result of
+    __builtin_frame_address (0) in the MinGW header file:
+    
+      define setjmp(BUF) _setjmp((BUF), __builtin_frame_address (0))
+    
+    This means that we directly expose the frame pointer to the SEH machinery
+    here (unlike with regular exception handling where we use an intermediate
+    CFA) and thus that we cannot do whatever we want with it.  The old code
+    would leave it unaligned, i.e. not multiple of 16, whereas the new code
+    aligns it, but this breaks for some reason; at least it appears that a
+    .seh_setframe directive with 0 as second argument always works, so the
+    fix aligns it this way.

Subject: [PATCH 0447/1725] wallet: compute waste for SelectionResults of
 preset inputs

When we use only manually specified inputs, we should still calculate
the waste so that if anything later on calls GetWaste (in order to log
it), there won't be an error.

Subject: [PATCH 0454/1725] Change wallet validation order

In the current code, the database is created before the last validation,
which checks that passphrase is set and private keys are disabled.

Therefore, if this validation fails, it will result in an empty database
and the user will not be able to recreate a wallet with the same name
and with the correct parameters.

Subject: [PATCH 0458/1725] contrib: Remove suspicious hosts list from
 makeseeds

I have some qualms with maintaining a suspicious hosts list as part as
the repository. But also, it's stale and irrelevant. I've checked the
entire list and none of them is connectable. Only one still appars in
`nodes_main.txt` but with low uptime and an old subversion string so it
wouldn't be picked in the first place.

Subject: [PATCH 0459/1725] Converted lint-tests.sh to python

Use raw string

Use re.search instead of grep in check_matching_test_names

Replaced bash commands in check_unique_test_names with python commands

Use set and sort output

Use set comprehension

Use .splitlines()

Call grep_boost_fixture_test_suite once

splitlines() once

Fixed copyright date

Use check_output() instead of run()

add encoding='utf8'

Use clearer code for getting duplicates

Subject: [PATCH 0477/1725] util: optimizes HexStr

In my benchmark, this rewrite improves runtime 27% (g++) to 46% (clang++) for the benchmark `HexStrBench`:

Note that the idea for this change comes from denis2342 in PR 23364. This is a rewrite so no unaligned accesses occur.

Also, the lookup table is now calculated at compile time, which hopefully makes the code a bit easier to review.

Subject: [PATCH 0478/1725] test: use MiniWallet for p2p_segwit.py

This change only affects the subtest `test_superfluous_witness`.

Note that instead of creating a raw transaction first and then
signing it, we go the other direction here: MiniWallet creates a
transaction spending a segwit v1 output (i.e. including a witness),
then we turn it into a raw transaction by dropping the witness.
Therefore, the debug log asserts are swapped.

Subject: [PATCH 0480/1725] miniscript: the 'd:' wrapper must not be 'u'

The value it leaves on the stack depends on the last element on the
stack. However, we can't make sure this element is OP_1 (which would
give us the 'u' property) without the MINIMALIF rule.
MINIMALIF is only policy for P2WSH, therefore giving 'd:' the 'u'
property breaks consensus soundness: it makes it possible (by consensus
but not policy) for instance to satisfy a thresh() without satisfying
at least k of its subs.

This bug was found and reported by Andrew Poelstra.

Subject: [PATCH 0501/1725] Clear pindexBestHeader in
 ChainstateManager::Unload()

-----

Code Reviewer Notes

Call graph of relevant functions:

UnloadBlockIndex() <-- Moved from
    calls ChainstateManager::Unload() <-- Moved to

Safe because ChainstateManager::Unload() is called only by
UnloadBlockIndex() and no other callers.

Subject: [PATCH 0503/1725] Clear fHavePruned in BlockManager::Unload()

Code Reviewer Notes

Call graph of relevant functions:

UnloadBlockIndex() <-- Moved from
    calls ChainstateManager::Unload()
        which calls BlockManager::Unload() <-- Moved to

So calling UnloadBlockIndex() would still run this moved code. The code
will also now run when ~BlockManager gets called, which makes sense.

@@ -31,15 +31,17 @@ Release Process
 * Update the following variables in [`src/chainparams.cpp`](/src/chainparams.cpp) for mainnet, testnet, and signet:
   - `m_assumed_blockchain_size` and `m_assumed_chain_state_size` with the current size plus some overhead (see
     [this](#how-to-calculate-assumed-blockchain-and-chain-state-size) for information on how to calculate them).
+  - The following updates should be reviewed with `reindex-chainstate` and `assumevalid=0` to catch any defect
+    that causes rejection of blocks in the past history.
   - `chainTxData` with statistics about the transaction count and rate. Use the output of the `getchaintxstats` RPC with an
     `nBlocks` of 4096 (28 days) and a `bestblockhash` of RPC `getbestblockhash`; see
     [this pull request](https://github.com/bitcoin/bitcoin/pull/20263) for an example. Reviewers can verify the results by running
     `getchaintxstats <window_block_count> <window_final_block_hash>` with the `window_block_count` and `window_final_block_hash` from your output.
-  - `nMinimumChainWork` and `defaultAssumeValid` (and the block height comment) with information from the `getblockheader` (and `getblockhash`) RPCs.
-    - The selected value must not be orphaned so it may be useful to set the value two blocks back from the tip.
-    - Testnet should be set some tens of thousands back from the tip due to reorgs there.
-    - This update should be reviewed with a reindex-chainstate with assumevalid=0 to catch any defect
-      that causes rejection of blocks in the past history.
+  - `defaultAssumeValid` with the output of RPC `getblockhash` using the `height` of `window_final_block_height` above
+    (and update the block height comment with that height), taking into account the following:
+    - On mainnet, the selected value must not be orphaned, so it may be useful to set the height two blocks back from the tip.
+    - Testnet should be set with a height some tens of thousands back from the tip, due to reorgs there.
+  - `nMinimumChainWork` with the "chainwork" value of RPC `getblockheader` using the same height as that selected for the previous step.
 - Clear the release notes and move them to the wiki (see "Write the release notes" below).
 - Translations on Transifex
     - Create [a new resource](https://www.transifex.com/bitcoin/bitcoin/content/) named after the major version with the slug `[bitcoin.qt-translation-<RRR>x]`, where `RRR` is the major branch number padded with zeros. Use `src/qt/locale/bitcoin_en.xlf` to create it.

Subject: [PATCH 0510/1725] [net processing] Inline and simplify
 UpdatePreferredDownload

We inline `UpdatePreferredDownload` because it is only used in one
location during the version handshake. We simplify it by removing the
initial subtraction of `state->fPreferredDownload` from
`nPreferredDownload`. This is ok since the version handshake is only
called once per peer and `state->fPreferredDownload` will always be
false before the newly inlined code is called, making the subtraction a
noop.

Subject: [PATCH 0512/1725] refactor: fix includes in src/compat

Add missing includes.

Swap C headers for their C++ counterparts.

Remove pointless / unmaintainable include comments. This is even more the case
when we are actually using IWYU, as if anyone wants to see the comments they can
just get IWYU to generate them.

Subject: [PATCH 0546/1725] Disallow more unsafe string->path conversions
 allowed by path append operators

Add more fs::path operator/ and operator+ overloads to prevent unsafe
string->path conversions on Windows that would cause strings to be
decoded according to the current Windows locale & code page instead of
the correct string encoding.

Update application code to deal with loss of implicit string->path
conversions by calling fs::u8path or fs::PathFromString explicitly, or
by just changing variable types from std::string to fs::path to avoid
conversions altoghther, or make them happen earlier.

In all cases, there's no change in behavior either (1) because strings
only contained ASCII characters and would be decoded the same regardless
of what encoding was used, or (2) because of the 1:1 mapping between
paths and strings using the PathToString and PathFromString functions.

+# Be aware that bitcoind and bitcoin-qt differ in terms of localization: Qt
+# opts in to POSIX localization by running setlocale(LC_ALL, "") on startup,
+# whereas no such call is made in bitcoind.
+#
+# Qt runs setlocale(LC_ALL, "") on initialization. This installs the locale
+# specified by the user's LC_ALL (or LC_*) environment variable as the new
+# C locale.
+#
+# In contrast, bitcoind does not opt in to localization -- no call to
+# setlocale(LC_ALL, "") is made and the environment variables LC_* are
+# thus ignored.
+#
+# This results in situations where bitcoind is guaranteed to be running
+# with the classic locale ("C") whereas the locale of bitcoin-qt will vary
+# depending on the user's environment variables.
+#
+# An example: Assuming the environment variable LC_ALL=de_DE then the
+# call std::to_string(1.23) will return "1.230000" in bitcoind but
+# "1,230000" in bitcoin-qt.
+#
+# From the Qt documentation:
+# "On Unix/Linux Qt is configured to use the system locale settings by default.
+#  This can cause a conflict when using POSIX functions, for instance, when
+#  converting between data types such as floats and strings, since the notation
+#  may differ between locales. To get around this problem, call the POSIX function
+#  setlocale(LC_NUMERIC,"C") right after initializing QApplication, QGuiApplication
+#  or QCoreApplication to reset the locale that is used for number formatting to
+#  "C"-locale."
+#
+# See https://doc.qt.io/qt-5/qcoreapplication.html#locale-settings and

-# Qt runs setlocale(LC_ALL, "") on initialization. This installs the locale
-# specified by the user's LC_ALL (or LC_*) environment variable as the new
-# C locale.
-#
-# In contrast, bitcoind does not opt in to localization -- no call to
-# setlocale(LC_ALL, "") is made and the environment variables LC_* are
-# thus ignored.
-#
-# This results in situations where bitcoind is guaranteed to be running
-# with the classic locale ("C") whereas the locale of bitcoin-qt will vary
-# depending on the user's environment variables.
-#
-# An example: Assuming the environment variable LC_ALL=de_DE then the
-# call std::to_string(1.23) will return "1.230000" in bitcoind but
-# "1,230000" in bitcoin-qt.
-#
-# From the Qt documentation:
-# "On Unix/Linux Qt is configured to use the system locale settings by default.
-#  This can cause a conflict when using POSIX functions, for instance, when
-#  converting between data types such as floats and strings, since the notation
-#  may differ between locales. To get around this problem, call the POSIX function
-#  setlocale(LC_NUMERIC,"C") right after initializing QApplication, QGuiApplication
-#  or QCoreApplication to reset the locale that is used for number formatting to
-#  "C"-locale."
-#
-# See https://doc.qt.io/qt-5/qcoreapplication.html#locale-settings and
-# https://stackoverflow.com/a/34878283 for more details.

Subject: [PATCH 0556/1725] test: MiniWallet: always rehash after signing (P2PK
 mode)

Also explicitly rehash in the cases where we modify a tx after signing
in feature_csv_activation.py. Parts of this test relied on the fact that
rehashing of transactions is done in the course of calculating a block's
merkle root (`calc_merkle_root`), which only works if no hash was
calculated before due to a caching mechanism.

In the following commit the txid in MiniWallet is calculated via
`rehash()`, i.e. this doesn't work anymore and we always have to
explicitely have the right hash before we calculate the merkle root.

Subject: [PATCH 0557/1725] test: MiniWallet: skip mempool check if
 `mempool_valid=False`

MiniWallet's core method for creating txs (`create_self_transfer`)
right now always executes the `testmempoolaccept` RPC to check for
mempool validity or invalidity. In some test cases where we use
MiniWallet to create a huge number of transactions this can lead
to performance issues (e.g. feature_fee_estimation.py where the
execution time after MiniWallet usage almost doubled). Providing
the possibility to skip the mempool checks is a mitigation for
this.

Subject: [PATCH 0560/1725] Delete UpdatePackagesForAdded at beginning of
 addPackageTxs.

As described in commit 9cea7e37158aa85119de2c81e93901da9e476ee5, this is no longer needed because priority transaction selection (addPriorityTxs) was removed in commit 272b25a6a99057fdcd5db5bce70b49625e973080.

Subject: [PATCH 0568/1725] prevector: only allow trivially copyable types

The prevector implementation currently can't be used with types that are
not trivially copyable, due to the use of memmove. Trivially copyable
implies that it is trivially destructible, see
https://eel.is/c++draft/class.prop#1.3

That means that the checks for std::is_trivially_destructible are not
necessary, and in fact where used it wouldn't be enough. E.g. in
`erase(iterator, iterator)` the elements in range first-last are destructed,
but it does not destruct elements left after `memmove`.

This commit removes the checks for `std::is_trivially_destructible`
and instead adds a `static_assert(std::is_trivially_copyable_v<T>);` to
make sure `prevector` is only used with supported types.

Subject: [PATCH 0572/1725] [netgroup] Use nStartByte as offset for the last
 byte of the group

Should we ever introduce a new address type that makes use of
`nStartByte` and adds fractional bytes to the group, then nStartByte
should be used as the offset for the last byte.

Subject: [PATCH 0573/1725] rpc: Explain active and internal in listdescriptors

The current help text for active and internal in listdescriptors is not
particularly helpful. They require the reader to already know what those
terms mean. This help text is updated to actually explain the
definitions of those words in context of a descriptor wallet.

+23.0 Release Notes
+==================
+
+Bitcoin Core version 23.0 is now available from:
+
+  <https://bitcoincore.org/bin/bitcoin-core-23.0/>
+
+This release includes new features, various bug fixes and performance
+improvements, as well as updated translations.
+
+Please report bugs using the issue tracker at GitHub:
+
+  <https://github.com/bitcoin/bitcoin/issues>
+
+To receive security and update notifications, please subscribe to:
+
+  <https://bitcoincore.org/en/list/announcements/join/>
+
+How to Upgrade
+==============
+
+If you are running an older version, shut it down. Wait until it has completely
+shut down (which might take a few minutes in some cases), then run the
+installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on Mac)
+or `bitcoind`/`bitcoin-qt` (on Linux).
+
+Upgrading directly from a version of Bitcoin Core that has reached its EOL is
+possible, but it might take some time if the data directory needs to be migrated. Old
+wallet versions of Bitcoin Core are generally supported.
+
+Compatibility
+==============
+
+Bitcoin Core is supported and extensively tested on operating systems
+using the Linux kernel, macOS 10.15+, and Windows 7 and newer.  Bitcoin
+Core should also work on most other Unix-like systems but is not as
+frequently tested on them.  It is not recommended to use Bitcoin Core on
+unsupported systems.
+
+Notable changes
+===============
+
+P2P and network changes
+-----------------------
+
+- A bitcoind node will no longer rumour addresses to inbound peers by default.
+  They will become eligible for address gossip after sending an ADDR, ADDRV2,
+  or GETADDR message. (#21528)
+
+- Before this release, Bitcoin Core had a strong preference to try to connect only to peers that listen on port 8333. As a result of that, Bitcoin nodes listening on non-standard ports would likely not get any Bitcoin Core peers connecting to them. This preference has been removed. (#23542)
+
+- Full support has been added for the CJDNS network. See the new option `-cjdnsreachable` and [doc/cjdns.md](https://github.com/bitcoin/bitcoin/tree/23.x/doc/cjdns.md) (#23077)
+
+Fee estimation changes
+----------------------
+
+- Fee estimation now takes the feerate of replacement (RBF) transactions into
+  account. (#22539)
+
+Rescan startup parameter removed
+--------------------------------
+
+The `-rescan` startup parameter has been removed. Wallets which require
+rescanning due to corruption will still be rescanned on startup.
+Otherwise, please use the `rescanblockchain` RPC to trigger a rescan. (#23123)
+
+Tracepoints and Userspace, Statically Defined Tracing support
+-------------------------------------------------------------
+
+Bitcoin Core release binaries for Linux now include experimental tracepoints which
+act as an interface for process-internal events. These can be used for review,
+debugging, monitoring, and more. The tracepoint API is semi-stable. While the API
+is tested, process internals might change between releases requiring changes to the
+tracepoints. Information about the existing tracepoints can be found under
+[doc/tracing.md](https://github.com/bitcoin/bitcoin/blob/23.x/doc/tracing.md) and
+usage examples are provided in [contrib/tracing/](https://github.com/bitcoin/bitcoin/tree/23.x/contrib/tracing).
+
+Updated RPCs
+------------
+
+- The `validateaddress` RPC now returns an `error_locations` array for invalid
+  addresses, with the indices of invalid character locations in the address (if
+  known). For example, this will attempt to locate up to two Bech32 errors, and
+  return their locations if successful. Success and correctness are only guaranteed
+  if fewer than two substitution errors have been made.
+  The error message returned in the `error` field now also returns more specific
+  errors when decoding fails. (#16807)
+
+- The `-deprecatedrpc=addresses` configuration option has been removed.  RPCs
+  `gettxout`, `getrawtransaction`, `decoderawtransaction`, `decodescript`,
+  `gettransaction verbose=true` and REST endpoints `/rest/tx`, `/rest/getutxos`,
+  `/rest/block` no longer return the `addresses` and `reqSigs` fields, which
+  were previously deprecated in 22.0. (#22650)
+- The `getblock` RPC command now supports verbosity level 3 containing transaction inputs'
+  `prevout` information.  The existing `/rest/block/` REST endpoint is modified to contain
+  this information too. Every `vin` field will contain an additional `prevout` subfield
+  describing the spent output. `prevout` contains the following keys:
+  - `generated` - true if the spent coins was a coinbase.
+  - `height`
+  - `value`
+  - `scriptPubKey`
+
+- The top-level fee fields `fee`, `modifiedfee`, `ancestorfees` and `descendantfees`
+  returned by RPCs `getmempoolentry`,`getrawmempool(verbose=true)`,
+  `getmempoolancestors(verbose=true)` and `getmempooldescendants(verbose=true)`
+  are deprecated and will be removed in the next major version (use
+  `-deprecated=fees` if needed in this version). The same fee fields can be accessed
+  through the `fees` object in the result. WARNING: deprecated
+  fields `ancestorfees` and `descendantfees` are denominated in sats, whereas all
+  fields in the `fees` object are denominated in BTC. (#22689)
+
+- Both `createmultisig` and `addmultisigaddress` now include a `warnings`
+  field, which will show a warning if a non-legacy address type is requested
+  when using uncompressed public keys. (#23113)
+
+Changes to wallet related RPCs can be found in the Wallet section below.
+
+New RPCs
+--------
+
+- Information on soft fork status has been moved from `getblockchaininfo`
+  to the new `getdeploymentinfo` RPC which allows querying soft fork status at any
+  block, rather than just at the chain tip. Inclusion of soft fork
+  status in `getblockchaininfo` can currently be restored using the
+  configuration `-deprecatedrpc=softforks`, but this will be removed in
+  a future release. Note that in either case, the `status` field
+  now reflects the status of the current block rather than the next
+  block. (#23508)
+
+Files
+-----
+
+* On startup, the list of banned hosts and networks (via `setban` RPC) in
+  `banlist.dat` is ignored and only `banlist.json` is considered. Bitcoin Core
+  version 22.x is the only version that can read `banlist.dat` and also write
+  it to `banlist.json`. If `banlist.json` already exists, version 22.x will not
+  try to translate the `banlist.dat` into json. After an upgrade, `listbanned`
+  can be used to double check the parsed entries. (#22570)
+
+Updated settings
+----------------
+
+- In previous releases, the meaning of the command line option
+  `-persistmempool` (without a value provided) incorrectly disabled mempool
+  persistence.  `-persistmempool` is now treated like other boolean options to
+  mean `-persistmempool=1`. Passing `-persistmempool=0`, `-persistmempool=1`
+  and `-nopersistmempool` is unaffected. (#23061)
+
+- `-maxuploadtarget` now allows human readable byte units [k|K|m|M|g|G|t|T].
+  E.g. `-maxuploadtarget=500g`. No whitespace, +- or fractions allowed.
+  Default is `M` if no suffix provided. (#23249)
+
+- If `-proxy=` is given together with `-noonion` then the provided proxy will
+  not be set as a proxy for reaching the Tor network. So it will not be
+  possible to open manual connections to the Tor network for example with the
+  `addnode` RPC. To mimic the old behavior use `-proxy=` together with
+  `-onlynet=` listing all relevant networks except `onion`. (#22834)
+
+Tools and Utilities
+-------------------
+
+- Update `-getinfo` to return data in a user-friendly format that also reduces vertical space. (#21832)
+
+- CLI `-addrinfo` now returns a single field for the number of `onion` addresses
+  known to the node instead of separate `torv2` and `torv3` fields, as support
+  for Tor V2 addresses was removed from Bitcoin Core in 22.0. (#22544)
+
+Wallet
+------
+
+- Descriptor wallets are now the default wallet type. Newly created wallets
+  will use descriptors unless `descriptors=false` is set during `createwallet`, or
+  the `Descriptor wallet` checkbox is unchecked in the GUI.
+
+  Note that wallet RPC commands like `importmulti` and `dumpprivkey` cannot be
+  used with descriptor wallets, so if your client code relies on these commands
+  without specifying `descriptors=false` during wallet creation, you will need
+  to update your code.
+
+- Newly created descriptor wallets will contain an automatically generated `tr()`
+  descriptor which allows for creating single key Taproot receiving addresses.
+
+- `upgradewallet` will now automatically flush the keypool if upgrading
+  from a non-HD wallet to an HD wallet, to immediately start using the
+  newly-generated HD keys. (#23093)
+
+- a new RPC `newkeypool` has been added, which will flush (entirely
+  clear and refill) the keypool. (#23093)
+
+- `listunspent` now includes `ancestorcount`, `ancestorsize`, and
+  `ancestorfees` for each transaction output that is still in the mempool.
+  (#12677)
+
+- `lockunspent` now optionally takes a third parameter, `persistent`, which
+  causes the lock to be written persistently to the wallet database. This
+  allows UTXOs to remain locked even after node restarts or crashes. (#23065)
+
+- `receivedby` RPCs now include coinbase transactions. Previously, the
+  following wallet RPCs excluded coinbase transactions: `getreceivedbyaddress`,
+  `getreceivedbylabel`, `listreceivedbyaddress`, `listreceivedbylabel`. This
+  release changes this behaviour and returns results accounting for received
+  coins from coinbase outputs. The previous behaviour can be restored using the
+  configuration `-deprecatedrpc=exclude_coinbase`, but may be removed in a
+  future release. (#14707)
+
+- A new option in the same `receivedby` RPCs, `include_immature_coinbase`
+  (default=`false`), determines whether to account for immature coinbase
+  transactions. Immature coinbase transactions are coinbase transactions that
+  have 100 or fewer confirmations, and are not spendable. (#14707)
+
+GUI changes
+-----------
+
+- UTXOs which are locked via the GUI are now stored persistently in the
+  wallet database, so are not lost on node shutdown or crash. (#23065)
+
+- The Bech32 checkbox has been replaced with a dropdown for all address types, including the new Bech32m (BIP-350) standard for Taproot enabled wallets.
+
+Low-level changes
+=================
+
+RPC
+---
+
+- `getblockchaininfo` now returns a new `time` field, that provides the chain tip time. (#22407)
+
+Tests
+-----
+
+- For the `regtest` network the activation heights of several softforks were
+  set to block height 1. They can be changed by the runtime setting
+  `-testactivationheight=name@height`. (#22818)

Subject: [PATCH 0591/1725] init: Allow -proxy="" setting values

This drops the `No proxy server specified. Use -proxy=<ip> or -proxy=<ip:port>`
error when a empty `-proxy=` command line argument, `bitcoin.conf` value, or
`settings.json` value is specified, and just makes bitcoin connect and listen
normally in these cases.

The error was originally added in https://github.com/bitcoin/bitcoin/pull/20003
to prevent a bare `-proxy` command line argument with no assignment from
clearing proxy settings. But it was implemented in an overbroad way breaking
empty `-proxy=` assignments as well.

The motivation for this change is to prevent a GUI bug that happens with
https://github.com/bitcoin/bitcoin/pull/15936, reported in
https://github.com/bitcoin/bitcoin/pull/15936#pullrequestreview-937685759 by
vasild, that happens after a proxy setting is enabled and disabled in the GUI.
But this change also makes sense on its own to remove a potentially confusing
error message.

Subject: [PATCH 0592/1725] build: Create .la library for crc32c

Libtool will yell at you if you try to link a shared library against
static ones.

This change creates a libtool archive library for crc32c and allows a
shared library to be linked against it portably.

Also specify -static in both:

- ..._la_CXXFLAGS so that libtool will avoid building two versions of
  each object (one PIC, one non-PIC). We just need the one that is
  suitable for static linking.
- ..._la_LDFLAGS so that libtool will create a static library.

[META] This change is done in preparation for a future commit where we
       link the libbitcoinkernel library against this one.

Subject: [PATCH 0593/1725] build: Create .la library for leveldb

Libtool will yell at you if you try to link a shared library against
static ones.

This change creates a libtool archive library for leveldb and allows a
shared library to be linked against it portably.

Also specify -static in both:

- ..._la_CXXFLAGS so that libtool will avoid building two versions of
  each object (one PIC, one non-PIC). We just need the one that is
  suitable for static linking.
- ..._la_LDFLAGS so that libtool will create a static library.

If we don't specify this, then libtool will build two versions of each
object and prefer the non-static PIC version of the object, which is
built with -DDLL_EXPORT -DPIC for mingw-w64 targets. This can cause
symbol resolution problems when we link this library against an
executable that does specify -all-static, since that will be built
without the -DDLL_EXPORT flag.

This is especially important for leveldb and memenv since they link
against libwinpthreads, which has difference symbols depending on
whether DLL_EXPORT is defined or not.

[META] This change is done in preparation for a future commit where we
       link the libbitcoinkernel library against this one.

Appendix:

The specific linker errors when linking memenv built without -all-static
against a bitcoind with -all-static look like:

Subject: [PATCH 0594/1725] build: Create .la library for bitcoincrypto

Libtool will yell at you if you try to link a shared library against
static ones.

This change creates a libtool archive library for bitcoincrypto and
allows a shared library to be linked against it portably.

Also specify -static in both:

- ..._la_CXXFLAGS so that libtool will avoid building two versions of
  each object (one PIC, one non-PIC). We just need the one that is
  suitable for static linking.
- ..._la_LDFLAGS so that libtool will create a static library.

[META] This change is done in preparation for a future commit where we
       link the libbitcoinkernel library against this one.

Subject: [PATCH 0595/1725] build: Separate lib_LTLIBRARIES initialization

Set lib_LTLIBRARIES with '=' to an empty value at the top of the
Makefile.am and append to it from the library-local block for
readability.

Here's the error you get if you don't set lib_LTLIBRARIES to be empty:

    error: lib_LTLIBRARIES must be set with '=' before using '+='

[META] In a subsequent commit, we're going to introduce a library and
       append it to lib_LTLIBRARIES in its local block, this makes
       things more readable.

 /**
  * Base32 encode.

Subject: [PATCH 0605/1725] Make DecodeBase{32,64} always return vector, not
 string

Base32/base64 are mechanisms for encoding binary data. That they'd
decode to a string is just bizarre. The fact that they'd do that
based on the type of input arguments even more so.

Subject: [PATCH 0611/1725] init: Reset mempool and chainman via reconstruction

Fixes https://github.com/bitcoin/bitcoin/issues/22964

Previously, we used UnloadBlockIndex() in order to reset node.mempool
and node.chainman. However, that has proven to be fragile (see
https://github.com/bitcoin/bitcoin/issues/22964), and requires
UnloadBlockIndex and its callees to be updated manually for each member
that's introduced to the mempool and chainman classes.

In this commit, we stop using the UnloadBlockIndex function and we
simply reconstruct node.mempool and node.chainman.

Since PeerManager needs a valid reference to both node.mempool and
node.chainman, we also move PeerManager's construction via `::make` to
after the chainstate activation sequence is complete.

There are no more callers to UnloadBlockIndex after this commit, so it
and its sole callees can be pruned.

The only caller that uses this is ~ChainTestingSetup() where we
immediately destroy the mempool afterwards.

Subject: [PATCH 0616/1725] validation: Prune UnloadBlockIndex and callees

In previous commits in this patchset, we've made sure that every
Unload/UnloadBlockIndex member function resets its own members, and does
not reach out to globals.

This means that their corresponding classes' default destructors can now
replace them, and do an even more thorough job without the need to be
updated for every new member variable.

Therefore, we can remove them, and also remove UnloadBlockIndex since
that's not used anymore.

Unfortunately, chainstatemanager_loadblockindex relies on
CChainState::UnloadBlockIndex, so that needs to stay for now.

Subject: [PATCH 0621/1725] tests: Do not always create a descriptor wallet in
 wallet_createwallet

The createwallet teswt for some invalid parameters incorrectly always
creates a descriptor wallet. This is unnecessary and also breaks the
test when bdb is not compiled in.

Subject: [PATCH 0622/1725] build: Extract the libbitcoinkernel library

I strongly recommend reviewing with the following git-diff flags:
  --patience --color-moved=dimmed-zebra

Extract out a libbitcoinkernel library linking in all files necessary
for using our consensus engine as-is. Link bitcoin-chainstate against
it.

See previous commit "build: Add example bitcoin-chainstate executable"
for more context.

We explicitly specify -fvisibility=default, which effectively overrides
the effects of --enable-reduced-exports since libbitcoinkernel requires
default symbol visibility

When compiling for mingw-w64, specify -static in both:

- ..._la_CXXFLAGS so that libtool will avoid building two versions of
  each object (one PIC, one non-PIC). We just need the one that is
  suitable for static linking.
- ..._la_LDFLAGS so that libtool will create a static library.

If we don't specify this, then libtool will prefer the non-static PIC
version of the object, which is built with -DDLL_EXPORT -DPIC for
mingw-w64 targets. This can cause symbol resolution problems when we
link this library against an executable that does specify -all-static,
since that will be built without the -DDLL_EXPORT flag.

Unfortunately, this means that for mingw-w64 we can only build a static
version of the library for now. This will be fixed.

However, on other targets, the shared library creation works fine.

-----

Note to users: You need to either specify:

  --enable-experimental-util-chainstate

or,

  --with-experimental-kernel-lib

To build the libbitcionkernel library. See the configure help for more
details.

Subject: [PATCH 0628/1725] util: Replace non-threadsafe strerror

Some uses of non-threadsafe `strerror` have snuck into the code since
they were removed in #4152. Add a wrapper `SysErrorString` for
thread-safe strerror alternatives and replace all uses of `strerror`
with this.

Add `strerror` to the locale-dependence linter to catch its use. Add
exemptions for bdb interface code (false positive) and strerror.cpp
(the only allowed use).

Also fix a bug in the regexp so that `_r` and `_s` variants are detected
again.

Subject: [PATCH 0633/1725] guix: consolidate kernel headers to 5.15

Given no reason to use an older version of the kernel headers for the
non-RISCV linux builds, consolidate all Linux builds to 5.15.x.

Note that using older kernel headers isn't some sort of compatibility
"hack", and glibc explicitly recommends against doing so. See:
https://sourceware.org/glibc/wiki/FAQ#What_version_of_the_Linux_kernel_headers_should_be_used.3F.

Subject: [PATCH 0634/1725] doc: add minimum required kernel version to
 dependencies.md

This matches the version of the kernel targeted when we build the glibcs
we use for release builds in Guix. Other versions / scenerios may
work, but for documentation purposes, this is the version that makes
sense to document, and something we can claim to officially support.

Subject: [PATCH 0661/1725] build: Fix `libmultiprocess` cross-compiling to
 Linux hosts

To successfully call the `capnp_generate_cpp()` function, the
`libmultiprocess` build system must be provided with paths to the native
`capnp` and `capnpc-c++` tools.

-##            Quick Primer on addnode vs connect            ##
-##  Let's say for instance you use addnode=4.2.2.4          ##
-##  addnode will connect you to and tell you about the      ##
-##    nodes connected to 4.2.2.4.  In addition it will tell ##
-##    the other nodes connected to it that you exist so     ##
-##    they can connect to you.                              ##
-##  connect will not do the above when you 'connect' to it. ##
-##    It will *only* connect you to 4.2.2.4 and no one else.##
-##                                                          ##
-##  So if you're behind a firewall, or have other problems  ##
-##  finding nodes, add some using 'addnode'.                ##
-##                                                          ##
-##  If you want to stay private, use 'connect' to only      ##
-##  connect to "trusted" nodes.                             ##
-##                                                          ##
-##  If you run multiple nodes on a LAN, there's no need for ##
-##  all of them to open lots of connections.  Instead       ##
-##  'connect' them all to one node that is port forwarded   ##
-##  and has lots of connections.                            ##

copy over bitcoin.conf during the build process.
this means `contrib/devtools/gen-bitcoin-conf.sh` will need
to be run and the generated file committed during the release process.

this is the same process used for generating man pages for each release.

Subject: [PATCH 0683/1725] Add RPC to get mempool txs spending outputs

We add an RPC to fetch the mempool transactions spending given outpoints.
Without this RPC, application developers would need to first call
`getrawmempool` which returns a long list of `txid`, then fetch each of
these txs individually to check whether they spend the given outpoint(s).

This RPC can later be enriched to also find confirmed transactions instead
of being restricted to mempool transactions.

Subject: [PATCH 0685/1725] Sanity assert GetAncestor() != nullptr where
 appropriate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add sanity asserts for return value of `CBlockIndex::GetAncestor()` where appropriate.

In validation.cpp `CheckSequenceLocks`, check the return value of `tip->GetAncestor(maxInputHeight)` stored into `lp->maxInputBlock`. If it ever returns `nullptr` because the ancestor isn't found, it's going to be a bad bug to keep going, since a `LockPoints` object with the `maxInputBlock` member set to `nullptr` signifies no relative lock time.

In the other places, the added asserts would prevent accidental dereferencing of a null pointer which is undefined behavior.

Subject: [PATCH 0696/1725] test: Remove extended lint (cppcheck)

These are unreferenced in the CI and documentation, and have been since
2019 (see #17549).

I'm not sure the cppcheck is worthwhile. It takes a long time
to run (I think this is why it isn't in the normal lints), and right
now it only appears to find implicit constructors. The list of
exceptions is out of date. But if anyone wants to bring it back at any
time in the future they can do so from git history (and port it to Python).

Subject: [PATCH 0700/1725] refactor: make MainSignalsInstance() a class

and use Doxygen documentation for it, per our developer notes.

Context:

MainSignalsInstance was created in 3a19fed9db5 and originally was a struct
collection of boost::signals methods moved to validationinterface.cpp, in order
to no longer need to include boost/signals in validationinterface.h.

MainSignalsInstance then evolved in d6815a23131 to remove boost/signals2 and became class-like.

[C.8: Use class rather than struct if any member is
non-public](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Rc-class)

[C.2: Use class if the class has an invariant; use struct if the data members can vary
independently](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#c2-use-class-if-the-class-has-an-invariant-use-struct-if-the-data-members-can-vary-independently)

A class also has the advantage of default private access, as opposed to public for a struct.

Subject: [PATCH 0703/1725] guix: bump time-machine to
 998eda3067c7d21e0d9bb3310d2f5a14b8f1c681

There are two reasons to perform this bump:
* Fixes #25082 by bumping to a commit that includes a fix for time-dependent unit
tests in libgit2 (f5fe0082abe4547f3fb9f29d8351473cfb3a387b).
* Gives us access to clang-toolchain-14 (14.0.3, 998eda3067c7d21e0d9bb3310d2f5a14b8f1c681),
which is useful for the Guix portion of #21778.

Note that with this bump:
Linux kernels headers update from 5.15.28 to 5.15.37.

+What is Bitcoin Core?
+---------------------
 
-Bitcoin is an experimental digital currency that enables instant payments to
-anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate
-with no central authority: managing transactions and issuing money are carried
-out collectively by the network. Bitcoin Core is the name of open source
-software which enables the use of this currency.
+Bitcoin Core connects to the Bitcoin peer-to-peer network to download and fully
+validate blocks and transactions. It also includes a wallet and graphical user
+interface, which can be optionally built.
 
-For more information read the original Bitcoin whitepaper.

+- When ordering function parameters, place input parameters first, then any

+
+- *Rationale*: API consistency.

+- Prefer returning values directly to using in-out or output parameters. Use
+  `std::optional` where helpful for returning values.

+- *Rationale*: Less error-prone (no need for assumptions about what the output
+  is initialized to on failure), easier to read, and often the same or better
+  performance.
+
+- Generally, use `std::optional` to represent optional by-value inputs (and
+  instead of a magic default value, if there is no real default). Non-optional
+  input parameters should usually be values or const references, while
+  non-optional in-out and output parameters should usually be references, as

+The [Clang `lifetimebound`

Subject: [PATCH 0722/1725] rpc: check `fopen` return code in dumptxoutset

This change improves the usability of the `dumptxoutset` RPC in two ways,
in the case that an invalid path is passed:
  1. return from the RPC immediately, rather then when the file is first
     tried to be written (which is _after_ calculating the UTXO set hash)
  2. return a proper return code and error message instead of the cryptic
     "CAutoFile::operator<<: file handle is nullptr: unspecified
      iostream_category error" (-1)

Subject: [PATCH 0726/1725] guix: compile glibc without -werror
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Compiling glibc 2.24 and 2.27 with the new GCC 10 results in a number of new warnings,
i.e:
```bash
libc-tls.c: In function ‘__libc_setup_tls’:
libc-tls.c:208:30: error: array subscript 1 is outside the bounds of an interior zero-length array ‘struct dtv_slotinfo[0]’ [-Werror=zero-length-bounds]
  208 |   static_slotinfo.si.slotinfo[1].map = main_map;
      |   ~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~
In file included from ../sysdeps/x86_64/ldsodefs.h:54,
                 from ../sysdeps/gnu/ldsodefs.h:46,
                 from ../sysdeps/unix/sysv/linux/ldsodefs.h:25,
                 from libc-tls.c:20:
../sysdeps/generic/ldsodefs.h:398:7: note: while referencing ‘slotinfo’
  398 |     } slotinfo[0];
      |       ^~~~~~~~
```

While we could try and backport all the patches required to fix these up, it would
currently seem easier to disable -Werror, which Guix uses by default when building
glibc.

Subject: [PATCH 0727/1725] guix: adjust RISC-V __has_include() patch to work
 with GCC 10

The actual macro is __has_include(), not __has_include__(), using the
later would result in build failures when using GCC 10. i.e:
```bash
../sysdeps/unix/sysv/linux/riscv/flush-icache.c:24:5: warning: "__has_include__" is not defined, evaluates to 0 [-Wundef]
   24 | #if __has_include__ (<asm/syscalls.h>)
```

Looks like at least someone else has run into the same thing, see:
http://lists.busybox.net/pipermail/buildroot/2020-July/590376.html.

Subject: [PATCH 0729/1725] guix: use -fcommon when building glibc 2.24

GCC 10 started using -fno-common by default, which causes issues with
the powerpc builds using gibc 2.24. A patch was commited to glibc to fix
the issue, 18363b4f010da9ba459b13310b113ac0647c2fcc but is non-trvial
to backport, and was broken in at least one way, see the followup in
commit 7650321ce037302bfc2f026aa19e0213b8d02fe6.

For now, retain the legacy GCC behaviour by passing -fcommon when
building glibc 2.24.

Subject: [PATCH 0734/1725] refactor: move StartExtraBlockRelayPeers from
 header to implementation

where all the other logging actions in src/net.{h,cpp} are located.

StartExtraBlockRelayPeers() does not appear to be a hotspot that needs to be
inlined for performance, as it is called from CheckForStaleTipAndEvictPeers(),
called in turn from StartScheduledTasks() with a scheduleEvery delta of 45
seconds, called at the end of AppInitMain() on bitcoind startup.

This allows dropping `#include <logging.h>` from net.h, which can improve
compile time/speed. Currently, none of the other includes in net.h use
logging.h, except src/sync.h if DEBUG_LOCKCONTENTION is defined.

MESSAGEMAP (e.g.: `t = MESSAGEMAP[msgtype]()`), the messages must have a
default constructor, i.e. there needs to be the possibility to
initialize them with zero arguments.

Subject: [PATCH 0744/1725] test: Fix race condition in index pruning test

Nodes are restarted and reconnected as part of the test. Afterwards
`sync_blocks` is called immediately on the nodes. `sync_blocks`
first checks that all the included nodes have at least one
connection. Since adding a connection is usually happening in a
thread, sometimes nodes could run into this check before the
connection was fully established so that it would fail the entire
test.

This fix uses the `connect_nodes` helper to make the connection the
nodes. `connect_nodes` has a wait for the connection built into it.

Subject: [PATCH 0747/1725] [net processing] Only accept `sendcmpct` with
 version=2

Subsequent commits will remove support for other versions of compact blocks.

Add a test that a received `sendcmpct` message with version = 1 is
ignored.

Subject: [PATCH 0754/1725] [net processing] Only relay blocks by cmpctblock
 and cache for fast relay if segwit is enabled

This introduces an early exit in PeerManagerImpl::NewPoWValidBlock() if
segwit has not been activated for the block. This means that we won't cache the
block/compact block for fast relay and won't relay the cmpctblock
immediately to peers that have requested hb compact blocks. This is fine
because any block where segwit is not yet activated is buried deep in
the chain, and so compact block relay will not be effective.

It's ok not to cache the block/compact block for fast relay for the same
reason - the block must be very deeply buried in the block chain.

ProcessBlockAvailability() also won't get called for all nodes. This is
also fine, since that function only updates hashLastUnknownBlock
and pindexBestKnownBlock, and is called early in every SendMessages()
call.

Subject: [PATCH 0757/1725] refactor: replace RecursiveMutex
 `m_most_recent_block_mutex` with Mutex

In each of the critical sections, only the the guarded variables are
accessed, without any chance that within one section another one is
called.  Hence, we can use an ordinary Mutex instead of RecursiveMutex.

Subject: [PATCH 0763/1725] bench: Add `--sanity-check` flag, use it in `make
 check`

The benchmarks are run as part of `make check` for a minimum sanity
check. The actual results are being ignored. So only run them for one
iteration.

This makes the `bench_bitcoin` part take 2m00 instead of 5m20 here.
Which is still too long (imo), but this needs to be solved in the
`WalletLoading*` benchmarks which take that long per iteration.

Subject: [PATCH 0765/1725] Remove fUseWTXID parameter from
 CBlockHeaderAndShortTxIDs constructor

All uses of CBlockHeaderAndShortTxIDs in the product code are
constructed with fUseWTXID=true, so remove the parameter.

There is one use of the CBlockHeaderAndShortTxIDs constructor with
fUseWTXID=false in the unit tests. This is used to construct a
CBlockHeaderAndShortTxIDs for a block with only the coinbase
transaction, so setting fUseWTXID to true or false makes no difference.

Suggested in https://github.com/bitcoin/bitcoin/pull/20799#pullrequestreview-963480278

Subject: [PATCH 0766/1725] Sync chain more readily from inbound peers during
 IBD

When in IBD, if the honest chain is only known by inbound peers, then we must
eventually sync from them in order to learn it. This change allows us to
perform initial headers sync and fetch blocks from inbound peers, if we have no
blocks in flight.

The restriction on having no blocks in flight means that we will naturally
throttle our block downloads to any such inbound peers that we may be
downloading from, until we leave IBD. This is a tradeoff between preferring
outbound peers for most of our block download, versus making sure we always
eventually will get blocks we need that are only known by inbound peers even
during IBD, as otherwise we may be stuck in IBD indefinitely (which could have
cascading failure on the network, if a large fraction of the network managed to
get stuck in IBD).

Subject: [PATCH 0768/1725] tracing: fix
 `coin_selection:aps_create_tx_internal` calling logic

According to the documentation, the tracepoint
`coin_selection:aps_create_tx_internal` "Is called when the second
`CreateTransactionInternal` with Avoid Partial Spends enabled completes."

Currently it is only called if the second call to
`CreateTransactionInternal` succeeds, i.e. the third parameter is always
`true` and we don't get notified in the case that it fails.

Fix this by introducing a boolean variable for the result of the call
and moving the tracepoint call outside the if body.

Subject: [PATCH 0769/1725] Fix -rpcwait with -netinfo printing negative time
 durations

Fixes negative time duration values in the "send", "recv",
and "age" columns (potentially the "txn" and "blk" columns also)
for the first run of -rpcwait -netinfo after bitcoind startup.

To reproduce, start bitcoind on mainnet and run
`bitcoin-cli -rpcwait -netinfo <n>` where n is 1 or larger.

The negative times will be larger/more apparent with a slower
CPU speed or e.g. higher checkblocks/checklevel config option
settings.

Subject: [PATCH 0776/1725] [test] Remove segwit argument from
 build_block_on_tip()

The only place that segwit=True is for a block that contains only the
coinbase transaction. Since the witness commitment is optional if none
of the transactions have a witness, we can leave it out. This doesn't
change the test coverage, which is testing p2p compact block logic.

Suggested in https://github.com/bitcoin/bitcoin/pull/20799#discussion_r867782119

Subject: [PATCH 0779/1725] net: add new method Sock::Listen() that wraps
 listen()

This will help to increase `Sock` usage and make more code mockable.

Subject: [PATCH 0780/1725] [net processing] [refactor] Move
 m_next_send_feefilter and m_fee_filter_sent

Move m_next_send_feefilter and m_fee_filter_sent out of the `TxRelay`
data structure. All of the other members of `TxRelay` are related to
sending transactions _to_ the peer, whereas m_fee_filter_sent and
m_next_send_feefilter are both related to receiving transactions _from_
the peer. A node's tx relay behaviour is not always symmetrical (eg a
blocksonly node will ignore incoming transactions, but may still send
out its own transactions), so it doesn't make sense to group the
feefilter sending data with the TxRelay data in a single structure.

This does not change behaviour, since IsBlockOnlyConn() is always equal
to !peer.m_tx_relay. We still don't send feefilter messages to outbound
block-relay-only peers (tested in p2p_feefilter.py).

Subject: [PATCH 0781/1725] [net processing] Comment all TxRelay members

This fully comments all the TxRelay members. The only significant change
is to the comment for m_relay_txs. Previously the comment stated that
one of the purposes of the field was that "We don't relay tx invs before
receiving the peer's version message". However, even without the
m_relay_txs flag, we would not send transactions to the peer before
receiving the `version` message, since SendMessages() returns
immediately if fSuccessfullyConnected is not set to true, which only
happens once a `version` and `verack` message have been received.

Subject: [PATCH 0783/1725] [net processing] Don't initialize TxRelay for
 non-tx-relay peers.

Delay initializing the TxRelay data structure for a peer until we receive
a version message from that peer. At that point we'll know whether it
will ever relay transactions. We only initialize the m_tx_relay
data structure if:

- this isn't an outbound block-relay-only connection; AND
- fRelay=true OR we're offering NODE_BLOOM to this peer
  (NODE_BLOOM means that the peer may turn on tx relay later)

Subject: [PATCH 0794/1725] index: Don't commit a best block before indexing it
 during sync

Committing a block prior to indexing would leave the index database
in an inconsistent state until it is indexed, which could corrupt the
index in case of a unclean shutdown. Thus commit its predecessor.

+- The `deprecatedrpc=exclude_coinbase` configuration option has been removed.
+  The `receivedby` RPCs (`listreceivedbyaddress`, `listreceivedbylabel`,
+  `getreceivedbyaddress` and `getreceivedbylabel`) now always return results
+  accounting for received coins from coinbase outputs, without an option to
+  change that behaviour. Excluding coinbases was previously deprecated in 23.0.

Subject: [PATCH 0799/1725] settings: Add update/getPersistent/isIgnored
 methods

Add interfaces::Node methods to give GUI finer grained control over
settings.json file. Update method is used to write settings to the file,
getPersistent and isIgnored methods are used to find out about settings
file and command line option interactions.

Subject: [PATCH 0800/1725] init: Remove Shutdown() node.args reset

This commit removes the `node.args = nullptr` assignment in the Shutdown()
function.

Clearing node.args there never made sense because it made the
Shutdown() function not idempotent, making it fragile and causing issues like
https://github.com/bitcoin/bitcoin/issues/23186.

The assignment also causes segfaults in GUI unit tests when a new
node().initParameterInteraction() call is added in OptionsModel to apply to Qt
settings (happens because AppTests calls Shutdown() which sets node.args to
null, and OptionTests runs after AppTests and then needs node.args not to be
null.)

Subject: [PATCH 0802/1725] refactor: Pass interfaces::Node references to
 OptionsModel constructor

Will allow OptionsModel to read/write settings to the node settings.json
file and share settings with the node, instead of storing them
externally in QSettings.

Subject: [PATCH 0803/1725] settings: Add resetSettings() method

Allows the GUI to clear settings.json file and save settings.json.bak file when
GUI "Reset Options" button is pressed or -resetguisettings command line option
is used. (GUI code already backs up and resets the "guisettings.ini" file this
way, so this just makes the same behavior possible for "settings.json")

+configure with `-DDEBUG_LOCKCONTENTION` added to your CPPFLAGS,

 You can then use the `-debug=lock` configuration option at bitcoind startup or
 `bitcoin-cli logging '["lock"]'` at runtime to turn on lock contention logging.

Subject: [PATCH 0815/1725] doc: remove passing `--disable-external-signer` in
 OpenBSD build guide

Since the Boost.Process usage check was added to the build system
(commit abc057c6030b2a0ddab46835a7801054da677781), passing the option
`--disable-external-signer` explicitly is not needed anymore on OpenBSD;
The configure script will automatically detect that including
<boost/process.hpp> leads to a compile error and disable external signer
support accordingly.

and inverse its logic.

The naming is out of date and incorrect, as lack of request of tx relay does not
imply block relay, and a preference for tx relay doesn't imply that block relay
isn't happening.

Subject: [PATCH 0823/1725] Add ChainstateManagerOpts, using as ::Options

[META] Although it seems like we don't need it for just one option,
       we're going to introduce another member to this struct *in the
       next commit*. In future patchsets for libbitcoinkernel decoupling
       it from ArgsManager, even more members will be added here.

Subject: [PATCH 0824/1725] Add ChainstateManager::m_adjusted_time_callback

This decouples validation.cpp from netaddress.cpp (transitively,
timedata.cpp, and asmap.cpp).

This is important for libbitcoinkernel as:

- There is no reason for the consensus engine to be coupled with
  netaddress, timedata, and asmap
- Users of libbitcoinkernel can now easily supply their own
  std::function that provides the adjusted time.

See the src/Makefile.am changes for some satisfying removals.

on m_chainparams.

We could allow for a std::shared_ptr to be passed in as m_chainparams,
but that complicates things further. Given that CChainParams is not an
entity class or struct, we can just copy it and have ChainstateManager
own it.

Subject: [PATCH 0826/1725] rpc: getreceivedbylabel, don't loop over the entire
 wallet txs map if no destinations were found for the input label.

If wallet.GetLabelAddresses() returns an empty vector (the wallet does not have addresses with that label in the addressbook) or if none of the returned destinations are from the wallet, we can return the function right away.

Subject: [PATCH 0828/1725] fuzz: Remove useless GetUTXOStats fuzz case

In the GetUTXOStats fuzz case, GetUTXOStats is always called with a
CCoinsViewCache. Which is guaranteed to throw a std::logic_error when
its ::Cursor() method is called on the first line of GetUTXOStats.

In the fuzz case, we basically catch this logic error and declare
victory if we caught it.

There is no point to fuzzing this deterministic logic.

Confirmed with IWYU that the node/coinstats.h #include is no longer
necessary.

Subject: [PATCH 0830/1725] coinstats: Extract hash_type in-member to in-param

Currently, CCoinsStats is a struct with both in-params and out-params
where the hash_type and index_requested members are the only in-params.

This change removes CCoinsStats' hash_type in-param member and adds it
to the relevant functions instead.

[META] In subsequent commits, all of CCoinsStats' members which serve as
       in-params will be moved out so as to make CCoinsStats a pure
       out-param struct.

Subject: [PATCH 0834/1725] Set effective_value when initializing a COutput

Previously in COutput, effective_value was initialized as the absolute
value of the txout, and fee as 0. effective_value along with fee were
calculated outside of the COutput constructor and set after the
object had been initialized. These changes will allow either the fee
or the feerate to be passed in a COutput constructor. If either are
provided, fee and effective_value are calculated and set in the
constructor. As a result, AvailableCoins also needs to be passed the
feerate when utxos are being spent. When balance is calculated or the
coins are being listed and feerate is neither available nor required,
AvailableCoinsListUnspent is used instead, which runs AvailableCoins
while providing the default value for feerate. Unit tests for the
calculation of effective value have also been added.

Subject: [PATCH 0837/1725] refactor: Remove defunct attributes.h includes

Since the removal of NODISCARD in 81d5af42f4dba5b68a597536cad7f61894dc22a3,
the only attributes def is LIFETIMEBOUND, and it's included in many more
places that it is used.

This removes all includes which do not have an associated use of LIFETIMEBOUND,
and adds it to the following files, due to their use of the same:
* src/validationinterface.h
* src/script/standard.h

Subject: [PATCH 0840/1725] Update GCSFilter benchmarks

Element count used in the GCSFilter benchmarks are increased to 100,000
from 10,000. Testing the benchmarks with different element counts showed
that a filter with 100,000 elements resulted in the same ns/op. This
this a desirable thing to have as it allows us to reason about how long
a single filter element takes to process, letting us easily calculate
how long a filter with N elements (where N > 100,000) would take to
process.

GCSFilterConstruct benchmark is now called without batch. This makes
intra-bench results more intuitive as all benchmarks are in ns/op
instead of a custom unit. There are no downsides to this change as
testing showed that there is no observable difference in error rates
in the benchmarks when calling without batch.

Subject: [PATCH 0842/1725] coinstats: Return purely out-param CCoinsStats

In previous commits in this patchset, we removed all in-param members of
CCoinsStats. Now that that's done, we can modify GetUTXOStats to return
an optional CCoinsStats instead of a status bool. Callers are modified
accordingly.

In rpc/blockchain.cpp, we discover that GetUTXOStats' status bool when
getting UTXO stats for pprev was not checked for error. We fix this as
well.

Subject: [PATCH 0843/1725] coinstats: Separate hasher/index lookup codepaths

Split out ComputeUTXOStats and LookupUTXOStatsWithIndex from
GetUTXOStats, since the hashing and indexing codepaths are quite
disparate in practice.

Also allow add a constructor to CCoinsStats for it to be constructed
from a a block height and hash. This is used in both codepaths.

Also add a note in GetUTXOStats documenting a behaviour quirk that
predates this patchset.

[META] This allows the hashing codepath to be moved to a separate file
       in a future commit, decoupling callers that only rely on the
       hashing codepath from the indexing one. This is key for
       libbitcoinkernel, which needs to have the hashing codepath for
       AssumeUTXO, but does not wish to be coupled with indexes.

Subject: [PATCH 0844/1725] Move logic from LookupUTXOStatsWithIndex to
 CoinStatsIndex::LookUpStats

The indexing codepath logic in node/coinstats.cpp is simple enough to be
moved into CoinStatsIndex::LookUpStats, avoiding an additional layer of
function calls. Callers are modified accordingly.

Also, add 2 missed BOOST_CHECKs to the coinstatsindex_initial_sync unit
test.

Subject: [PATCH 0845/1725] coinstats: Move hasher codepath to kernel/coinstats

As mentioned in a previous commit, the hashing codepath can now be moved
to a separate file. This decouples callers that only rely on the hashing
codepath from the indexing one.

This is key for libbitcoinkernel, which needs to have the CoinsStats
hashing codepath for AssumeUTXO, but does not wish to be coupled with
indexes.

Note that only the .cpp file is split in this commit, the header files
will be split in a subsequent commit and the #includes to
node/coinstats.h will be adjusted to only #include the necessary
headers.

Subject: [PATCH 0846/1725] coinstats: Split node/coinstats.h to
 kernel/coinstats.h

Most of this commit is pure-move.

After this change:

- kernel/coinstats.h
    -> Contains declarations for:
       - enum class CoinStatsHashType
       - struct CCoinsStats
       - GetBogoSize(...)
       - TxOutSer(...)
       - ComputeUTXOStats(...)
- node/coinstats.h
    -> Just GetUTXOStats, which will be removed as we change callers to
       directly use the hashing/indexing codepaths in future commits.

Subject: [PATCH 0848/1725] scripted-diff: Move src/kernel/coinstats to
 kernel::

Introduces a new kernel:: namespace and move all of src/kernel/coinstats
under it.

In the verify script, lines like:

line="$(grep -n 'namespace node {' -- src/kernel/coinstats.h | tail -n1 | cut -d: -f1)"
sed -i -e "${line}s@namespace node {@namespace kernel {@" -- src/kernel/coinstats.h

Are intended to replace only the last instance of "namespace node" with
"namespace kernel", this is to avoid replacing forward declarations of
things inside the node:: namespace.

Subject: [PATCH 0850/1725] kernel: Use ComputeUTXOStats in validation

This is the "fruit of our labor" for this patchset.
ChainstateManager::PopulateAndValidateSnapshot can now directly call
ComputeUTXOStats(...).

Our consensus engine is now fully decoupled from all indices.

See the src/Makefile.am for some satisfying removals.

Subject: [PATCH 0851/1725] coinstats: Move GetUTXOStats to rpc/blockchain

rpc/blockchain.cpp is now the only user of the vestigial
GetUTXOStats(...). And since GetUTXOStats(...)'s special fallback logic
was only really relevant/meant for rpc/blockchain.cpp, we can just move
it there.

https://cirrus-ci.com/task/5275612980969472?logs=lint#L849

I added 'nd' to the spelling.ignored-words.txt, as it's valid miniscript.

Subject: [PATCH 0858/1725] Get time less often in
 AddrManImpl::ResolveCollisions_()

This makes the code less verbose. Also, future changes that change how
to get the time are less verbose.

Moreover, GetAdjustedTime() might arbitrarily change the value during
the execution of this function. For example, the system time advances
over a second boundary, or the network adjusts the time arbitrarily.
Most of the time however the value will not change, so it seems better
to always lock the value in this scope for clarity.

 severity

This is more consistent with the other functions, as well as with the
logging output itself. If we want to make this change, we should do it
before it's all over the place.

 such file or directory

Error was reported by SatoriHoshiAiko in
https://github.com/bitcoin/bitcoin/issues/25207 and happens unpredictably
because make doesn't always build dependencies in the same order.

The source file src/ipc/capnp/protocol.cpp includes some generated headers so
needs to have an explicit dependency specified in the makefile so the headers
will be generated before the file is compiled. #19160 added the explicit
dependency, but it was incorrect because it referred to an old file path from
before the source file was renamed (ipc.cpp -> protocol.cpp)

Subject: [PATCH 0871/1725] Migrate -dbcache setting from QSettings to
 settings.json

This is just the first of multiple settings that will be stored in the bitcoin
persistent setting file and shared with bitcoind, instead of being stored as Qt
settings backed by the windows registry or platform specific config files which
are ignored by bitcoind.

Subject: [PATCH 0874/1725] Migrate -upnp and -natpmp settings from QSettings
 to settings.json

This also effectively reverts 58e8364dcdc4e57b0caac09f8402e6535301de9b from
#18077, applying upnp and natpmp settings from the optionsmodel class instead
of the optionsdialog class. This makes sense because model code, not view code
is responsible for applying all other settings, and because leaving these
settings half-applied in optionsmodel seems error prone and could lead to bugs.
(These things were discussed a little in
https://github.com/bitcoin/bitcoin/pull/18077#discussion_r560381734)

Subject: [PATCH 0879/1725] Add release notes about unified bitcoin-qt and
 bitcoind persistent settings

If a bitcoind setting like pruning, port mapping, or a network proxy is enabled
in the GUI, it will now be stored in the bitcoin persistent setting file and
shared with bitcoind, instead of being stored as Qt settings backed by the
windows registry or platform specific config files.

+GUI changes
+-----------
+
+Configuration changes made in the bitcoin GUI (such as the pruning setting,
+proxy settings, UPNP preferences) are now saved to `<datadir>/settings.json`
+file rather than to the Qt settings backend (windows registry or unix desktop
+config files), so these settings will now apply to bitcoind, instead of being
+ignored.
+
+Also, the interaction between GUI settings and `bitcoin.conf` settings is
+simplified. Settings from `bitcoin.conf` are now displayed normally in the GUI
+settings dialog, instead of in a separate warning message ("Options set in this
+dialog are overridden by the configuration file: -setting=value"). And these
+settings can now be edited because `settings.json` values take precedence over
+`bitcoin.conf` values.

Subject: [PATCH 0881/1725] Pass Peer& to Misbehaving()

`Misbehaving` has several coding related issues (ignoring the conceptual
issues here for now):
* It is public, but it is not supposed to be called from outside of
  net_processing. Fix that by making it private and creating a public
  `UnitTestMisbehaving` method for unit testing only.
* It doesn't do anything if a `nullptr` is passed. It would be less
  confusing to just skip the call instead. Fix that by passing `Peer&`
  to `Misbehaving()`.
* It calls `GetPeerRef`, causing `!m_peer_mutex` lock annotations to be
  propagated. This is harmless, but verbose. Fix it by removing the no
  longer needed call to `GetPeerRef` and the no longer needed lock
  annotations.

Subject: [PATCH 0887/1725] compat: remove glibcxx sanity checks

These checks were added in #4339, (see also #4081), to test
our back-compat stubs, however, those stubs no-longer exist (#22930),
meaning that these checks are now just testing some specific standard
library behaviour, without a particular rationale, or reason, compared
to any other standard library functions we use.

There has also been some discussion about the sanity checks in the
context of the libbitcoinkernel refactoring, see
https://github.com/bitcoin/bitcoin/pull/25065#discussion_r880668218.
Removing the checks removes the need to worry about atleast the glibcxx
checks.

Also remove the list of check from the doc in init.h, because it is
incomplete, and anyone who wants to know what checks are included can
look at the function.

Subject: [PATCH 0892/1725] wallet: CommitTransaction, remove extra wtx lookup
 and add exception for a possible db write error.

1) `Wallet::AddToWallet` is already returning the pointer to the inserted `CWalletTx`, so there is no need to look it up in the map again.

2) `Wallet::AddToWallet` can only return a nullptr if the db `writeTx` call failed. Which should be treated as an error.

Subject: [PATCH 0893/1725] Remove no-op TIME_INIT on deser

Assigning TIME_INIT to nTime was needed to fully re-initialize a dirty
object where the deserialization might skip nTime.
See https://github.com/bitcoin/bitcoin/pull/19020/files#r427620111

Now that the without-nTime logic is removed in commit
dbcb5742c48fd26f77e500291d7083e12eec741b and commit
e08770bed187bfa66f525d42e484579bcea78bba, the logic here can be removed
as well.

Also, remove confusing and redundant preprocessor code.

Also, remove no longer needed version.h include, which was needed for
INIT_PROTO_VERSION.

Subject: [PATCH 0894/1725] miniscript: mark nodes with duplicate keys as
 insane

As stated on the website, duplicate keys make it hard to reason about
malleability as a single signature may unlock multiple paths.

We use a custom KeyCompare function instead of operator< to be explicit
about the requirement.

Subject: [PATCH 0900/1725] test: Use MiniWallet in rpc_rawtransaction.py

This test was previously run twice, once with `--legacy-wallet` and once with
`--descriptors`.
Now we run it only with `--legacy-wallet`, as all the tests has been
ported to the MiniWallet but `raw_multisig_transaction_legacy_tests`,
which can be run only with the legacy wallet.
We also decrease the number of nodes used from 4 to 3, making the test
run slightly faster.

Subject: [PATCH 0912/1725] contrib: Use asmap for ASN lookup in makeseeds

Add an argument `-a` to provide a asmap file to do the IP to ASN
lookups.

This speeds up the script greatly, and makes the output deterministic.
Also removes the dependency on `dns.lookup`.

I've annotated the output with ASxxxx comments to provide a way to
verify the functionality.

For now I've added instructions in README.md to download and use the
`demo.map` from the asmap repository. When we have some other mechanism
for distributing asmap files we could switch to that.

This continues #24824. I've removed all the fallbacks and extra
complexity, as everyone will be using the same instructions anyway.

Subject: [PATCH 0920/1725] test: Use Set/UnsetGlobals in BasicTestingSetup

...instead of calling initialization functions directly and having to
keep around a ECCVerifyHandle member variable.

This makes the initialization codepath of our tests more closely
resemble those of AppInitMain and potentially eases the review of
subsequent commit removing init::{Set,Unset}Globals.

[META] In a future commit, we will introduce a kernel::Context which
       calls init::{Set,Unset}Globals in its ctor and dtor. It will be
       owned by node::NodeContext, so in the end, this patchset won't
       have made the previously local ECCVerifyHandle global.

+    A class representing a custom variable-length binary encoder/decoder for

+    minval and clsbits.
+
+    The encoding is easiest to describe using an example. Let's say minval=100 and
+    clsbits=[4,2,2,3]. In that case:
+    - x in [100..115]: encoded as [0] + [4-bit BE encoding of (x-100)].

+    - x in [124..131]: encoded as [1,1,1] + [3-bit BE encoding of (x-124)].
+
+    In general, every number is encoded as:
+    - First, k "1"-bits, where k is the class the number falls in (there is one class
+      per element of clsbits).
+    - Then, a "0"-bit, unless k is the highest class, in which case there is nothing.
+    - Lastly, clsbits[k] bits encoding in big endian the position in its class that
+      number falls into.
+    - Every class k consists of 2^clsbits[k] consecutive integers. k=0 starts at minval,
+      other classes start one past the last element of the class before it.

Subject: [PATCH 0930/1725] init: Initialize globals with kernel::Context's
 life

...instead of explicitly calling init::{Set,Unset}Globals.

Cool thing about this is that in both the testing and bitcoin-chainstate
codepaths, we no longer need to explicitly unset globals. The
kernel::Context goes out of scope and the globals are unset
"automatically".

Also construct kernel::Context outside of AppInitSanityChecks()

Subject: [PATCH 0937/1725] Bugfix: RPC/blockchain: pruneblockchain: Return the
 height of the actual last pruned block

From 0.14 (2017 Mar) until before 0.19 (2019 Nov), the height of the last
block pruned was returned, subject to a bug if there were blocks left unpruned
due to sharing files with later blocks.

In #15991, this was "fixed" to the current implementation, introducing a new
bug: now, it returns the first *unpruned* block.

Since the user provides the parameter as a block to include in pruning, it
makes more sense to fix the behaviour to match the documentation.

Subject: [PATCH 0945/1725] miner: Make mempool optional for BlockAssembler

...also adjust callers

Changes:

- In BlockAssembler::CreateNewBlock, we now only lock m_mempool->cs and
  call addPackageTxs if m_mempool is not nullptr
- BlockAssembler::addPackageTxs now takes in a mempool reference, and is
  annotated to require that mempool's lock.
- In TestChain100Setup::CreateBlock and generateblock, don't construct
  an empty mempool, just pass in a nullptr for mempool

Subject: [PATCH 0954/1725] guix: re-revert riscv execstack workaround

Now that we use GCC 10 for release builds, we no-longer need to
pass-Wl,-z,noexecstack to get a non-executable stack in RISC-V binaries.

This was originally removed in #21036, but then re-added in #21799, when
we reverted to using GCC 8.

Subject: [PATCH 0957/1725] logging: use LogPrintfCategory rather than a manual
 category

Here we update only the log messages that manually print a category.

In upcoming commits, LogPrintCategory will likely be used in many
other cases, such as to replace `LogPrintf` where it makes sense.

Subject: [PATCH 0966/1725] wallet: add 'only_spendable' filter to
 AvailableCoins
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We are skipping the non-spendable coins that appear in vCoins ('AvailableCoins' result) later, in several parts of the CreateTransaction and GetBalance flows:

GetAvailableBalance (1) gets all the available coins calling AvailableCoins and, right away, walk through the entire vector, skipping the non-spendable coins, to calculate the total balance.

Inside CreateTransactionInternal —> SelectCoins(vCoins,...), we have several calls to AttemptSelection which, on each of them internally, we call twice to GroupOutputs which internally has two for-loops over the entire vCoins vector that skip the non-spendable coins.

So, Purpose is not add the non-spendable coins into the AvailableCoins result (vCoins) in the first place for the processes that aren’t using them at all, so we don’t waste resources skipping them later so many times.

Note: this speedup is for all the processes that call to CreateTransaction and GetBalance* internally.

Subject: [PATCH 0972/1725] net: introduce Sock::WaitMany()

It allows waiting concurrently on more than one socket. Being a
`virtual` `Sock` method it can be overriden by tests.

Will be used to replace `CConnman::SocketEvents()`.

Subject: [PATCH 0973/1725] net: use Sock::WaitMany() instead of
 CConnman::SocketEvents()

Rename `GenerateSelectSet()` to `GenerateWaitSockets()` and adapt it to
generate a wait data suitable for `Sock::WaitMany()`. Then call it from
`CConnman::SocketHandler()` and feed the generated data to
`Sock::WaitMany()`.

This way `CConnman::SocketHandler()` can be unit tested because
`Sock::WaitMany()` is mockable, so the usage of real sockets can be
avoided.

Subject: [PATCH 0974/1725] GetExternalSigner(): fail if multiple signers are
 found

If there are multiple external signers, `GetExternalSigner()` will
just pick the first one in the list. If the user has two or more
hardware wallets connected at the same time, he might not notice this.

This PR adds a check and fails with suitable message.

Subject: [PATCH 0975/1725] build: test for timingsafe_bcmp

Code introduced in #15649 added usage of `timingsafe_bcmp()`, if
available, otherwise falling back to our own implementation. However
the relevant build system check was never added, so currently, we'll
always just use our implementation, as HAVE_TIMINGSAFE_BCMP will never
be defined.

Add the check for timingsafe_bcmp. Note that as far as I'm aware, it's
only available on OpenBSD.

Subject: [PATCH 0979/1725] compat: Consolidate mingw-w64 ASLR workaround for
 upstream libsecp changes

Achieve this by adding a MAIN_FUNCTION macro, consolidating the docs, and
introducing the macro across our distributed binaries.

Also update the docs to explain that anyone using binutils < 2.36 is
effected by this issue. Release builds are not, because they use binutils
2.37. Currently LTS Linux distros, like Ubuntu Focal, ship with 2.34.

+If you have more than one computer at your disposal, you can use [distcc](https://www.distcc.org) to speed up compilation. This is easiest when all computers run the same operating system and compiler version.

Subject: [PATCH 0992/1725] refactor: Introduce
 PeerManagerImpl::RejectIncomingTxs

Currently there are some confusions in net_processing:

* There is confusion between `-blocksonly mode` and `block-relay-only`,
  so adjust all comments to use the same nomenclature.
* Whether to disconnect peers for providing invs/txs is implemented
  differently. For example, it seems a bit confusing to disconnect
  `block-relay-only` peers with `relay` permission when they send a tx
  message, but not when they send an inv message. Also, keeping track of
  their inv announcements seems both wasteful and confusing, as it does
  nothing. This isn't possible in practice, as outbound connections do
  not have permissions assigned, but sees fragile to rely on. Especially
  in light of proposed changes to make that possible:

Subject: [PATCH 1002/1725] test: remove unused `create_confirmed_utxos` helper

Confirmed UTXOs in functional tests can simply be created by using
MiniWallet's `send_self_transfer_multi` method with a subsequent
`generate` call to mine a block.

Remove all the files we don't use.
This should not change behavior, or anything at all, as none of these
files are currently used in our build system.

-# UniValue
-
-## Summary
-
-A universal value class, with JSON encoding and decoding.
-
-UniValue is an abstract data type that may be a null, boolean, string,
-number, array container, or a key/value dictionary container, nested to
-an arbitrary depth.
-
-This class is aligned with the JSON standard, [RFC
-7159](https://tools.ietf.org/html/rfc7159.html).
-
-## Library usage
-
-This is a fork of univalue used by Bitcoin Core. It is not maintained for usage
-by other projects. Notably, the API is broken in non-backward-compatible ways.
-
-Other projects looking for a maintained library should use the upstream
-univalue at https://github.com/jgarzik/univalue.

-# ===========================================================================

-# ===========================================================================
-#
-# SYNOPSIS
-#
-#   AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
-#
-# DESCRIPTION
-#
-#   Check for baseline language coverage in the compiler for the specified
-#   version of the C++ standard.  If necessary, add switches to CXX and
-#   CXXCPP to enable support.  VERSION may be '11' (for the C++11 standard)
-#   or '14' (for the C++14 standard).
-#
-#   The second argument, if specified, indicates whether you insist on an
-#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
-#   -std=c++11).  If neither is specified, you get whatever works, with
-#   preference for no added switch, and then for an extended mode.
-#
-#   The third argument, if specified 'mandatory' or if left unspecified,
-#   indicates that baseline support for the specified C++ standard is
-#   required and that the macro should error out if no mode with that
-#   support is found.  If specified 'optional', then configuration proceeds
-#   regardless, after defining HAVE_CXX${VERSION} if and only if a
-#   supporting mode is found.

Subject: [PATCH 1005/1725] refactor: cleanups post unsubtree'ing univalue

Mostly changes to remove src/univalue exceptions from the various linters,
and the required code changes to make them happy. As well as minor doc
changes.

Subject: [PATCH 1013/1725] guix: use libtool 2.4.7

As of version 2.4.7, libtool now respects ARFLAGS, which we use, and has
changed the default ARFLAGS from cru to cr (which we also do, see
configure).

This eliminates spammy `ar` output such as:
```bash
  CXXLD    libunivalue.la
/root/.guix-profile/bin/x86_64-linux-gnu-ar: `u' modifier ignored since `D' is the default (see `U')
  AR       libbitcoin_zmq.a
  AR       libbitcoin_consensus.a

Seeking to make the `CoinControl` option less confusing/redundant.

In #16377 the `CoinControl` flag ‘m_add_inputs’ was added to tell the coin filtering and selection process two things:
	- Coin Filtering: Only use the provided inputs. Skip the Rest.
	- Coin Selection: Search the wtxs-outputs and append all the `CoinControl` selected outpoints to the selection result (skipping all the available output checks). Nothing else.

Meanwhile, in `CoinControl` we already have a flag ‘fAllowOtherInputs’ which is already saying:
	- Coin Filtering: Only use the provided inputs. Skip the Rest.
	- Coin Selection: If false, no selection process -> append all the `CoinControl` selected outpoints to the selection result (while they passed all the `AvailableCoins` checks and are available in the 'vCoins' vector).

As can notice, the first point in the coin filtering process is duplicated in the two option flags. And the second one, is slightly different merely because it takes into account whether the coin is on the `AvailableCoins` vector or not.
So it makes sense to merge ‘m_add_inputs’ and ‘fAllowOtherInputs’ into a single field for the coin filtering process while introduce other changes to add the missing/skipped coins into 'vCoins' vector if they were manually selected by the user (follow-up commits).

Subject: [PATCH 1025/1725] wallet: move "use-only coinControl inputs" below
 the selected inputs lookup

Otherwise, RPC commands such as `walletcreatefundedpsbt` will not support the manual selection of locked, spent and externally added coins.

Full explanation is inside #25118 comments but brief summary is:

`vCoins` at `SelectCoins` time could not be containing the manually selected input because, even when they were selected by the user, the current `AvailableCoins` flow skips locked and spent coins.

Extra note: this is an intermediate step to unify the `fAllowOtherInputs`/`m_add_inputs` concepts. It will not be a problem anymore in the future when we finally decouple the wtx-outputs lookup process from `SelectCoins` and don't skip the user's manually selected coins in `AvailableCoins`.

Subject: [PATCH 1036/1725] build: globally define NOMINMAX

Define (and document) `NOMINMAX` once, rather than across multiple
source files.

Defining this prevents the definition of min/max macros when using
mingw-w64, which may conflict with unprefixed std::min/max usage. While
that might not be the case for us, we'd always prefer to use the standard
library in any case.

For example:
https://github.com/mingw-w64/mingw-w64/blob/73cadc06c62c6af5faf76f64ef08e684b48de48c/mingw-w64-headers/include/ntdef.h#L289-L300

Subject: [PATCH 1042/1725] net: remove CloseSocket()

Do the closing in `Sock::Reset()` and remove the standalone
`CloseSocket()`.

This reduces the exposure of low-level sockets (i.e. integer file
descriptors) outside of the `Sock` class.

Subject: [PATCH 1044/1725] guix: remove explicit glibc stack protector
 disabling

While glibc 2.25 and newer *can* be built with stack-smashing-protection
enabled, it isn't used by default, and still isn't, as of glibc 2.35,
so I can't see a reason to explicitly disable it.

I'd also like to move in the direction of enabling, by default,
hardening options for the toolchains we build, so removing the explicit
disabling is a step in that direction.

Will be following up with some changes based on this PR.

Rather than abusing the member variables self._priv_key and
self._address to determine the MiniWallet mode, save it explicitly
instead in the constructor to increase the readability and
maintainability of the code.

Subject: [PATCH 1047/1725] qt6: Fix type registration

In Qt 6, registration of `QDataStream` streaming operators is done
automatically. Consequently, `qRegisterMetaTypeStreamOperators()` does
no longer exist. Calls to this method have to be removed when porting
to Qt 6.

See https://doc.qt.io/qt-6/qtcore-changes-qt6.html#the-qmetatype-class

-or building and depending on a local version of Berkeley DB 4.8. The readily available Arch Linux packages are currently built using
-`--with-incompatible-bdb` according to the [PKGBUILD](https://github.com/archlinux/svntogit-community/blob/packages/bitcoin/trunk/PKGBUILD).
-As mentioned above, when maintaining portability of the wallet between the standard Bitcoin Core distributions and independently built

Subject: [PATCH 1064/1725] net: rename Sock::Reset() to Sock::Close() and make
 it private

Outside of `Sock`, `Sock::Reset()` was used in just one place (in
`i2p.cpp`) which can use the assignment operator instead.

This simplifies the public `Sock` API by having one method less.

Subject: [PATCH 1065/1725] refactor: Replace feeDelta by m_modified_fee

* feeDelta tracked the delta (to be applied on top of the actual fee)
* m_modified_fee tracks the actual fee with the delta included
* Instead of passing in the new total delta to the Updater, pass in by
  how much the total delta should be modified.

This is needed for the next commit, but makes sense on its own because
the same is done by UpdateDescendantState and UpdateAncestorState.

package relay doesn't exist. However, a regtest-only interface allows
wallet/application devs to test current package policies.

Subject: [PATCH 1084/1725] build: suppress array-bounds errors in libxkbcommon

These occur when building with GCC 12.1.

It might be the case that these would be suppressed by updating the
package, but that would also require installing new build tools (meson),
as well as potentially more dependencies (wayland).

```bash
In function 'ExprCreateBoolean',
    inlined from 'BoolVarCreate' at src/xkbcomp/ast-build.c:316:19:

Subject: [PATCH 1085/1725] build: use BOOST_NO_CXX98_FUNCTION_BASE to suppress
 warnings

Boost conatiner_hash (included via functional -> multi_index) uses
std::unary_function, which was deprecated in C++11, and "removed" in
C++17. It's use causes wanrings with newer compilers, i.e GCC 12.1.

```bash
/bitcoin/depends/aarch64-unknown-linux-gnu/include/boost/container_hash/hash.hpp:131:33:
warning: 'template<class _Arg, class _Result> struct std::unary_function' is deprecated [-Wdeprecated-declarations]
  131 |         struct hash_base : std::unary_function<T, std::size_t> {};
      |                                 ^~~~~~~~~~~~~~
In file included from /usr/include/c++/12/bits/unique_ptr.h:37,
                 from /usr/include/c++/12/memory:76,
                 from ./init.h:10,
                 from init.cpp:10:
/usr/include/c++/12/bits/stl_function.h:117:12: note: declared here
  117 |     struct unary_function
```

Use the MACRO outlined in
https://github.com/boostorg/container_hash/issues/22, to prevent it's
use.

BOOST_NO_CXX98_FUNCTION_BASE:
> The standard library no longer supports std::unary_function and std::binary_function.
> They were deprecated in C++11 and is removed from C++14.

Subject: [PATCH 1086/1725] wallet: Save wallet scan progress

Currently, the wallet scan progress is not saved.
If it is interrupted,  it will be necessary to start from
scratch on the next load.
With this change, progress is saved every 60 seconds.

Subject: [PATCH 1097/1725] ci: Increase CPU number for "Win64 native" task

Currently, the time it takes to get the "Win64 native" task done with
all of the caches been invalidated is very close to the 2 hours limit.

This task is the only one which runs on Windows Community Cluster,
therefore this change should not affect other CI tasks.

 function

To make it easier to de/serialize individual KeyOriginInfo for PSBTs,
separate the actual de/serialization of KeyOriginInfo to its own
function.

This is an additional separation where any length prefix is processed by
the caller.

Subject: [PATCH 1115/1725] Add serialization methods to XOnlyPubKey

CPubKey does.

Subject: [PATCH 1119/1725] Store TaprootBuilder in SigningProviders instead of
 TaprootSpendData

TaprootSpendData can be gotten from TaprootBuilder, however for PSBT, we
also need TaprootBuilders directly (for the outputs). So we store the
TaprootBuilder in the FlatSigningProvider and when the TaprootSpendData
is needed, we generate it on the fly using the stored builder.

GetSpendData needs to be finalized in order to be used. To avoid future
bugs, assert `!m_output_key.IsNull()` as m_output_key is only set during
Finalize.

Subject: [PATCH 1128/1725] sign: Use sigdata taproot spenddata when signing

The taproot spenddata stored in a sigdata is the combination of data
existing previously (e.g. in a PSBT) and the data stored in a
SigningProvider. In order to use the external data when signing, we need
to be using the sigdata's spenddata.

Subject: [PATCH 1129/1725] wallet: also search taproot pubkeys in FillPSBT

When filling a PSBT, we search the listed pubkeys in order to determine
whether the current DescriptorScriptPubKeyMan could sign the transaction
even if it is not watching the scripts. With Taproot, the taproot
pubkeys need to be searched as well.

Subject: [PATCH 1137/1725] pool: Add and use MemPoolOptions,
 ApplyArgsManOptions

Reviewers: Note that CTxMemPool now requires a non-defaulted
CTxMemPool::Options for its constructor. Meaning that there's no need to
worry about a stray CTxMemPool constructor somewhere defaulting to
something incorrect. All instances of CTxMemPool construction are
addressed here in this commit.

We set options for CTxMemPool and construct it in many different ways. A
good example can be seen in how we determine CTxMemPool's check_ratio in
AppInitMain(...).

1. We first set the default based on chainparams's
   DefaultConsistencyChecks()
2. Then, we apply the ArgsManager option on top of that default
3. Finally, we clamp the result of that between 0 and 1 Million

With this patch, most CTxMemPool construction are along the lines of:

    MemPoolOptions mempool_opts{...default overrides...};
    ApplyArgsManOptions(argsman, mempool_opts);
    ...hard overrides...
    CTxMemPool pool{mempool_opts};

This "compositional" style of building options means that we can omit
unnecessary/irrelevant steps wherever we want but also maintain full
customizability.

For example:

- For users of libbitcoinkernel, where we eventually want to remove
  ArgsManager, they simply won't call (or even know about)
  ApplyArgsManOptions.

- See src/init.cpp to see how the check_ratio CTxMemPool option works
  after this change.

A MemPoolOptionsForTest helper was also added and used by tests/fuzz
tests where a local CTxMemPool needed to be created.

The change in src/test/fuzz/tx_pool.cpp seemingly changes behaviour by
applying ArgsManager options on top of the CTxMemPool::Options defaults.
However, in future commits where we introduce flags like -maxmempool,
the call to ApplyArgsManOptions is actually what preserves the existing
behaviour. Previously, although it wasn't obvious, our CTxMemPool would
consult gArgs for flags like -maxmempool when it needed it, so it
already relied on ArgsManager information. This patchset just laid bare
the obfuscatory perils of globals.

[META] As this patchset progresses, we will move more and more
       CTxMemPool-relevant options into MemPoolOptions and add their
       ArgsMan-related logic to ApplyArgsManOptions.

Subject: [PATCH 1138/1725] mempool: Pass in -maxmempool instead of referencing
 gArgs

- Store the mempool size limit (-maxmempool) in CTxMemPool as a member.

- Remove the requirement to explicitly specify a mempool size limit for
  CTxMemPool::GetMinFee(...) and LimitMempoolSize(...), just use the
  stored mempool size limit where possible.

- Remove all now-unnecessary instances of:
    gArgs.GetIntArg("-maxmempool", DEFAULT_MAX_MEMPOOL_SIZE_MB) * 1000000

The code change in CChainState::GetCoinsCacheSizeState() is correct
since the coinscache should not repurpose "extra" mempool memory
headroom for itself if the mempool doesn't even exist.

The version of GetMinFee() with a custom size specification is and
should only be used by tests. Mark it as protected and use a derived

Subject: [PATCH 1141/1725] mempool: Pass in -mempoolexpiry instead of
 referencing gArgs

- Store the mempool expiry (-mempoolexpiry) in CTxMemPool as a
  std::chrono::seconds member.

- Remove the requirement to explicitly specify a mempool expiry for
  LimitMempoolSize(...), just use the newly-introduced member.

- Remove all now-unnecessary instances of:

Subject: [PATCH 1143/1725] scripted-diff: Rename anc/desc size limit vars to
 indicate SI unit

Better to be explicit when it comes to sizes to avoid unintentional
bugs. We use MB and KB all over the place.

They live as a CTxMemPool member.

[META] These limits will be used in subsequent commits to replace calls

Subject: [PATCH 1147/1725] mempool: Use m_limit for
 UpdateTransactionsFromBlock

Since:

- UpdateTransactionsFromBlock is only called by
  MaybeUpdateMempoolForReorg, which calls it with the gArgs-determined
  ancestor limits
- UpdateForDescendants is only called by UpdateTransactionsFromBlock
  with the ancestor limits unchanged

We can remove the requirement to specify the ancestor limits for both
UpdateTransactionsFromBlock and UpdateForDescendants and just use the
values in the m_limits member.

Also move some removed comments to MemPoolLimits struct members.

The uint64_t cast in UpdateForDescendants is not new behavior,
see the diff in CChainState::MaybeUpdateMempoolForReorg for where they

Subject: [PATCH 1150/1725] Move additional headers fetching to own function

Also moves the call to happen directly after validation of a headers message
(rather than mixed in with other state updates for the peer), and removes an
incorrect comment in favor of one that explains why headers sync must continue
from the last header a peer has sent.

Subject: [PATCH 1155/1725] Don't send getheaders message when another request
 is outstanding

Change getheaders messages so that we wait up to 2 minutes for a response to a
prior getheaders message before issuing a new one.

Also change the handling of the getheaders message sent in response to a block
INV, so that we no longer use the hashstop variable (including the hash stop
will just mean that if our peer's headers chain is longer, then we won't learn
it, so there's no benefit to using hashstop).

Also, now respond to a getheaders during IBD with an empty headers message
(rather than nothing) -- this better conforms to the intent of the new logic
that it's better to not ignore a peer's getheaders message, even if you have
nothing to give. This also avoids a lot of functional tests breaking.

p2p_segwit.py is modified to use this same strategy, as the test logic (of
expecting a getheaders after a block inv) would otherwise be broken.

Subject: [PATCH 1156/1725] init: Remove redundant -*mempool*, -limit* queries

Now that MemPoolOptions has correctly-determined max_size and limits
members, perform sanity checks on that instead of re-determining the
options.

Subject: [PATCH 1158/1725] Revert "bnb: exit selection when best_waste is 0"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This reverts commit 9b5950db8683f9b4be03f79ee0aae8a780b01a4b.

Waste can be negative. At feerates lower than long_term_feerate this
means that a waste of 0 may be a suboptimal solution and this causes the
search to exit prematurely.
Only when the feerate is equal to the long_term_feerate would achieving
a waste of 0 indicate that we have achieved an optimal solution,
because it would mean that the excess is 0. It seems unlikely
that this would ever occur outside of test cases, and even then we
should prefer solutions with more inputs over solutions with fewer
according to previous decisions—but solutions with more inputs are found
later in the branch exploration.

The "optimization" described in #18257 and implemented in #18262 is
therefore a premature exit on a suboptimal solution and should be reverted.

Subject: [PATCH 1164/1725] util: remove MSVC warning pragmas

4786 - I don't think this exists any more?
4805 - Is already defined (globally) in the MSVC project.

Dropped 4717 and 4804, as it seems they are no-longer supressing
anything.

See:

This assures that changing the internals of the helper function

Subject: [PATCH 1167/1725] test: let `gen_return_txouts` create a single large
 OP_RETURN output

Transactions with more than one datacarrier (OP_RETURN) output
are never considered standard, i.e. this change is necessary in
order to to get rid of the `acceptnonstdtxn` option for some
tests.

Subject: [PATCH 1168/1725] test: pass `datacarriersize` option for tests using
 large outputs (instead of `acceptnonstdtxn`)

By specifying the `datacarriersize` option instead of the more
generic `acceptnonstdtxn`, we can be more specific about what
part of the transaction is non-standard and can be sure that all
other aspects follow the standard policy.

Subject: [PATCH 1169/1725] qt: apply translator comments to reset options
 confirmation dialog

Follow-up to #617. This applies translator strings to the
reset options confirmation dialog and also refactors the way we pass the
strings to the dialog in order to allow the comments to be applied.
Because the strings were being concatenated, we can not apply translator
comments to all of the relevant strings. What we want to do instead is
have a variable in which the translatable strings are appended to using
the QString append function. This satisfies the Qt translator engine and
the comments are then properly applied within the `extracomment` field
in the translation file.

Subject: [PATCH 1175/1725] psbt: Check Taproot tree depth and leaf versions

Since TaprootBuilder has assertions for the depth and leaf versions, the
PSBT decoder should check these values before calling
TaprootBuilder::Add so that the assertions are not triggered on
malformed taproot trees.

Subject: [PATCH 1185/1725] test: hook into PID in tracing tests

This makes sure to NOT hook into other bitcoind binaries run in
paralell in the test framework. We only want to trace the intended
binary.

In interface_usdt_utxocache.py:
While testing the utxocache flush with pruning, bitcoind is
restarted and we need to hook into the new PID again.

Subject: [PATCH 1186/1725] test: adopt USDT utxocache interface tests

The USDT interface exposes process internals via the tracepoints. This
means, the USDT interface tests somewhat awardly depend on these
internals. If internals change, the tests have to adopt to that change.
Previously, the USDT interface tests weren't run in the CI so changes
could break the USDT interface tests without being noticed (e.g.
https://github.com/bitcoin/bitcoin/pull/25486).

In fa13375aa3fcb4fd5b9e0d4c69ac31cf66c3209a a 'self.rescan_utxos()' call
was added in the 'generate()' function of the test framework.
'rescan_utxos()' causes the UTXO cache to be flushed. In the USDT
interface tests for the 'utxocache:flush' trancepoint, 'generate()' is
used. As the utxo cache is now flushed more often, the number of flushes
the tests expectes need to be adopted. Also, the utxo cache has now a
different size when being flushed.

The utxocache tracepoint is tested by shutting the node down and
pruning blocks, to test the 'for_prune' argument.

Changes:
- A list 'expected_flushes' is now used which contains 'mode',
  'for_prune', and 'size' for each expected flush.
- When a flush happens, the expected-flush is removed from the list.
  This list is checked to be empty (unchanged).
- Previously, shutting down caused these two flushes:
    UTXOCacheFlush(duration=*, mode=ALWAYS, size=104, memory=*, for_prune=False)
    UTXOCacheFlush(duration=*, mode=ALWAYS, size=0, memory=*, for_prune=False)
  now it causes these flushes:
    UTXOCacheFlush(duration=*, mode=ALWAYS, size=2, memory=*, for_prune=False)
    UTXOCacheFlush(duration=*, mode=ALWAYS, size=0, memory=*, for_prune=False)
  The 104 UTXOs flushed previously were mainly coinbase UTXOs generated
  in previous tests and the test setup. These are now already flushed.
- In the 'for_prune' test we previously hooked into the tracepoint
  before mining blocks. This changed to only get notified about the
  tracepoint being triggered for the prune. Here, the utxo cache is
  empty already as it has just been flushed in 'generate()'.
  old:
    UTXOCacheFlush(duration=*, mode=NONE, size=350, memory=*, for_prune=True)
  new:
    UTXOCacheFlush(duration=*, mode=NONE, size=0, memory=*, for_prune=True)

Subject: [PATCH 1187/1725] test: pass `dustrelayfee=0` option for tests using
 dust (instead of `acceptnonstdtxn=1`)

By specifying the `dustrelayfee=0` option instead of the more
generic `acceptnonstdtxn=1`, we can be more specific about what
part of the transaction is non-standard and can be sure that all
other aspects follow the standard policy.

Subject: [PATCH 1205/1725] wallet: don't iter twice when getting the cached
 debit/credit amount

Instead of calling GetCachableAmount twice, which will result in
iterating through all the transaction txins/txouts and calling
GetDebit/GetCredit (which lock cs_wallet), just merge the filters and do
it once.

-ARM Cross-compilation
--------------------
-These steps can be performed on, for example, an Ubuntu VM. The depends system
-will also work on other Linux distributions, however the commands for
-installing the toolchain will be different.
-
-Make sure you install the build requirements mentioned above.
-Then, install the toolchain and curl:
-
-    sudo apt-get install g++-arm-linux-gnueabihf curl
-
-To build executables for ARM:
-
-    cd depends
-    make HOST=arm-linux-gnueabihf NO_QT=1
-    cd ..
-    ./autogen.sh
-    CONFIG_SITE=$PWD/depends/arm-linux-gnueabihf/share/config.site ./configure --enable-reduce-exports LDFLAGS=-static-libstdc++
-    make
-
-
-For further documentation on the depends system see [README.md](../depends/README.md) in the depends directory.

Subject: [PATCH 1214/1725] Introduce `mempoolfullrbf` node setting.

This new node policy setting enables to accept replaced-by-fee
transaction without inspection of the replaceability signaling
as described in BIP125 "explicit signaling".

If turns on, the node mempool accepts transaction replacement
as described in `policy/mempool-replacements.md`.

The default setting value is `false`, implying opt-in RBF
is enforced.

 Instructions

NetBSD doc has not seen any meaningful contribution since 2018.
This PR intends to update the docs so that one can successfully build on
the latest NetBSD release. It also adds dependency information and
instructions to build the GUI.

-NetBSD Build Guide
-======================
-**Updated for NetBSD [8.0](https://www.netbsd.org/releases/formal-8/NetBSD-8.0.html)**
+# NetBSD Build Guide
 
-This guide describes how to build bitcoind and command-line utilities on NetBSD.
+Updated for NetBSD [9.2](https://netbsd.org/releases/formal-9/NetBSD-9.2.html).
 
-This guide does not contain instructions for building the GUI.
+This guide describes how to build bitcoind, command-line utilities, and GUI on NetBSD.
 
-Preparation
--------------
+## Preparation
 
-You will need the following modules, which can be installed via pkgsrc or pkgin:
+### 1. Install Required Dependencies
+
+Install the required dependencies the usual way you [install software on NetBSD](https://www.netbsd.org/docs/guide/en/chap-boot.html#chap-boot-pkgsrc).
+The example commands below use `pkgin`.
+
+```bash
+pkgin install autoconf automake libtool pkg-config git gmake boost libevent
 
 ```
-autoconf
-automake
-boost
-git
-gmake
-libevent
-libtool
-pkg-config
-python37
 
-git clone https://github.com/bitcoin/bitcoin.git
+NetBSD currently ships with an older version of `gcc` than is needed to build. You should upgrade your `gcc` and then pass this new version to the configure script.
+
+For example, grab `gcc9`:
+```
+pkgin install gcc9
+```
+
+Then, when configuring, pass the following:
+```bash
+./configure
+    ...
+    CC="/usr/pkg/gcc9/bin/gcc" \
+    CXX="/usr/pkg/gcc9/bin/g++" \
+    ...
 ```
 
 See [dependencies.md](dependencies.md) for a complete overview.
 
-### Building Bitcoin Core
+### 2. Clone Bitcoin Repo
 
-**Important**: Use `gmake` (the non-GNU `make` will exit with an error).
+Clone the Bitcoin Core repository to a directory. All build scripts and commands will run from this directory.
 
-#### With descriptor wallet:
+```bash
+git clone https://github.com/bitcoin/bitcoin.git
+```
+
+### 3. Install Optional Dependencies
+
+#### Wallet Dependencies
+
+It is not necessary to build wallet functionality to run bitcoind or the GUI.
+
+###### Descriptor Wallet Support
+
+`sqlite3` is required to enable support for [descriptor wallets](https://github.com/bitcoin/bitcoin/blob/master/doc/descriptors.md).
 
-The descriptor wallet uses `sqlite3`. You can install it using:
 ```bash
 pkgin install sqlite3
 ```
 
+###### Legacy Wallet Support
+
+`db4` is required to enable support for legacy wallets.
+
 ```bash
-./autogen.sh
-./configure --with-gui=no --without-bdb \
-    CPPFLAGS="-I/usr/pkg/include" \
-    LDFLAGS="-L/usr/pkg/lib" \
-    BOOST_CPPFLAGS="-I/usr/pkg/include" \
-    MAKE=gmake
+pkgin install db4
 ```
 
-#### With legacy wallet:
-
-BerkeleyDB is use for legacy wallet functionality.
+#### GUI Dependencies
 
-It is recommended to use Berkeley DB 4.8. You cannot use the BerkeleyDB library
-from ports.
-You can use [the installation script included in contrib/](/contrib/install_db4.sh) like so:
+Bitcoin Core includes a GUI built with the cross-platform Qt Framework. To compile the GUI, we need to install `qt5`.
 
 ```bash
-./contrib/install_db4.sh `pwd`
+pkgin install qt5
 ```
 
-from the root of the repository. Then set `BDB_PREFIX` for the next section:
+The GUI can encode addresses in a QR Code. To build in QR support for the GUI, install `qrencode`.
 
 ```bash
-export BDB_PREFIX="$PWD/db4"
+pkgin install qrencode
 ```
 
+#### Test Suite Dependencies
+
+There is an included test suite that is useful for testing code changes when developing.
+To run the test suite (recommended), you will need to have Python 3 installed:
+
 ```bash
-./autogen.sh
-./configure --with-gui=no CPPFLAGS="-I/usr/pkg/include" \
-    LDFLAGS="-L/usr/pkg/lib" \
-    BOOST_CPPFLAGS="-I/usr/pkg/include" \
-    BDB_LIBS="-L${BDB_PREFIX}/lib -ldb_cxx-4.8" \
-    BDB_CFLAGS="-I${BDB_PREFIX}/include" \
-    MAKE=gmake
+pkgin install python37
 ```
 
-#### Without wallet:
+### Building Bitcoin Core
+
+**Note**: Use `gmake` (the non-GNU `make` will exit with an error).
+
+
+### 1. Configuration
+
+There are many ways to configure Bitcoin Core. Here is an example that
+explicitly disables the wallet and GUI:
+
 ```bash
 ./autogen.sh
-./configure --with-gui=no --disable-wallet \
+./configure --without-wallet --with-gui=no \
     CPPFLAGS="-I/usr/pkg/include" \
-    LDFLAGS="-L/usr/pkg/lib" \
-    BOOST_CPPFLAGS="-I/usr/pkg/include" \
     MAKE=gmake
 ```
 
+For a full list of configuration options, see the output of `./configure --help`
+
+### 2. Compile
+
 Build and run the tests:
+
 ```bash
 gmake # use "-j N" here for N parallel jobs
-gmake check
+gmake check # Run tests if Python 3 is available
 ```

 Introduction
 ---------------------
-Solution and project files to build Bitcoin Core with `msbuild` or Visual Studio can be found in the `build_msvc` directory. The build has been tested with Visual Studio 2022 and Visual Studio 2019 (building with earlier versions of Visual Studio should not be expected to work).
+Visual Studio 2022 is minimum required to build Bitcoin Core.
+
+Solution and project files to build with `msbuild` or Visual Studio can be found in the `build_msvc` directory.
 
 To build Bitcoin Core from the command-line, it is sufficient to only install the Visual Studio Build Tools component.

Subject: [PATCH 1226/1725] refactor: add most of src/util to iwyu

These files change infrequently, and not much header shuffling is required.

We don't add everything in src/util/ yet, because IWYU makes some
dubious suggestions, which I'm going to follow up with upstream.

Subject: [PATCH 1227/1725] Introduce generic 'Result' class

Useful to encapsulate the function result object (in case of having it) or, in case of failure, the failure reason.

This let us clean lot of boilerplate code, as now instead of returning a boolean and having to add a ref arg for the
return object and another ref for the error string. We can simply return a 'BResult<Obj>'.

Example of what we currently have:
```
bool doSomething(arg1, arg2, arg3, arg4, &result, &error_string) {
    do something...
    if (error) {
        error_string = "something bad happened";
        return false;
    }

    result = goodResult;
    return true;
}
```

Example of what we will get with this commit:
```
BResult<Obj> doSomething(arg1, arg2, arg3, arg4) {
    do something...
    if (error) return {"something happened"};

    // good
    return {goodResult};
}
```

This allows a similar boilerplate cleanup on the function callers side as well. They don't have to add the extra
pre-function-call error string and result object declarations to pass the references to the function.

Subject: [PATCH 1231/1725] ci: run USDT interface test in a VM

Our CI tasks are run by CirrusCI in Docker containers in a Google
Compute Engine based Kubernetes environment. These containers have
limited capabilities - especially CAP_SYS_ADMIN is missing. See
https://github.com/bitcoin/bitcoin/issues/23296#issuecomment-1024920845

We need elevated privileges to hook into the USDT tracepoints. We use a
CirrusCI "compute_engine_instance" (a VM, not a container) where we have
the required privileges. The ubunut-mininmal-2204-lts was choosen with
debian-11 being an alternative. Both pack an outdated 'bpfcc-tools'
package (v0.18.0) from 2020. This version prints warnings to stderr
during BPF bytecode compilation, which causes our functional test runner
to fail. This is fixed in newer verison.

Until debian-12 or a newer Ubuntu release is avaliable as image in GCE
(https://cloud.google.com/compute/docs/images/os-details), we use a
third-party and untrusted PPA that releases up-to-date versions of the
package.

The official iovisor (authors of BCC) PPA is outdated too. An
alternative would be to compile BCC from source in the CI.

Subject: [PATCH 1235/1725] wallet: Precompute Txdata after setting PSBT
 inputs' UTXOs

If we are given a PSBT that is missing one or more input UTXOs, our
PrecomputedTransactionData will be incorrect and missing information
that it should otherwise have, and therefore we may not produce a
signature when we should. To avoid this problem, we can do the
precomputation after we have set the UTXOs the wallet is able to set for
the PSBT.

Also adds a test for this behavior.

Subject: [PATCH 1249/1725] Expose underlying clock in CThreadInterrupt

Overloading sleep_for is not needed, as

* seconds and minutes can be converted to milliseconds by the compiler,
  not needing a duration_cast
* std::condition_variable::wait_for will convert milliseconds to the
  duration type of the underlying clock

So simply expose the clock.

Subject: [PATCH 1254/1725] rpc: Select int-UniValue constructor for enum value
 in upgradewallet RPC

UniValue does not have a constructor for enum values, however the
compiler will decay the enum into an int and select that constructor.
Avoid this compiler magic and clarify the code by explicitly selecting
the int-constructor.

This is needed for the next commit.

This is helpful for finer grained descriptor parsing error: when there
are multiple errors to report in a Miniscript descriptor start with the
"smallest" fragments: the ones closer to be a leaf.

Subject: [PATCH 1258/1725] Miniscript support in output descriptors

Miniscript descriptors are defined under P2WSH context (either `wsh()`
or `sh(wsh())`).
Only sane Miniscripts are accepted, as insane ones (although valid by
type) can have surprising behaviour with regard to malleability
guarantees and resources limitations.
As Miniscript descriptors are longer and more complex than "legacy"
descriptors, care was taken in error reporting to help a user determine

Subject: [PATCH 1260/1725] univalue: Avoid narrowing and verbose int
 constructors

As UniValue provides several constructors for integral types, the
compiler is unable to select one if the passed type does not exactly
match. This is unintuitive for developers and forces them to write
verbose and brittle code.

For example, there are many places where an unsigned int is cast to a
signed int. While the cast is safe in practice, it is still needlessly
verbose and confusing as the value can never be negative. In fact it
might even be unsafe if the unsigned value is large enough to map to a
negative signed one.

Subject: [PATCH 1264/1725] [tests] Connect peer in
 outbound_slow_chain_eviction by sending p2p messages

Prior to this commit, the peer was connected, and then the services and
connectivity fields in the CNode object were manually set. Instead, send
p2p `version` and `verack` messages, and have net_processing's internal
logic set the state of the node.

This ensures that the node's internal state is consistent with how it
would be set in the live code.

Prior to this commit, `dummyNode1.nServices` was set to `NODE_NONE`
which was not a problem since `CNode::fClient` and
`CNode::m_limited_node` are default initialised to false. Now that we
are doing the actual version handshake, the values of `fClient` and
`m_limited_node` are set during the handshake and cause the test to fail
if we do not set `dummyNode1.nServices` to a reasonable value
(NODE_NETWORK | NODE_WITNESS).

Subject: [PATCH 1271/1725] wallet: allow to fetch the wallet descriptors for a
 given Script

We currently expose a method to get the signing providers, which allows
to infer a descriptor from the scriptPubKey. But in order to identify
"on" what descriptor a coin was received, we need access to the
descriptors that were imported to the wallet.

+Wallet
+------
+
+- The `wsh()` output descriptor was extended with Miniscript support. You can import Miniscript
+  descriptors for P2WSH in a watchonly wallet to track coins, but you can't spend from them using
+  the Bitcoin Core wallet yet.
+  You can find more about Miniscript on the [reference website](https://bitcoin.sipa.be/miniscript/).
+
+
+Low-level changes
+=================
+
+RPC
+---
+
+- The `deriveaddresses`, `getdescriptorinfo`, `importdescriptors` and `scantxoutset` commands now
+  accept Miniscript expression within a `wsh()` descriptor.
+
+- The `getaddressinfo`, `decodescript`, `listdescriptors` and `listunspent` commands may now output
+  a Miniscript descriptor inside a `wsh()` where a `wsh(raw())` descriptor was previously returned.

Subject: [PATCH 1274/1725] DumpMempool: Pass in dump_path, stop using gArgs

Also introduce node::{ShouldPersistMempool,MempoolPath} helper functions
in node/mempool_persist_args.{h,cpp} which are used by non-kernel
DumpMempool callers to determine whether or not to automatically dump
the mempool and where to dump it to.

Subject: [PATCH 1278/1725] Disallow encryption of watchonly wallets

Watchonly wallets do not have any private keys to encrypt. It does not
make sense to encrypt such wallets, so disable the option to encrypt
them.

This avoids an assertion that can be hit when encrypting watchonly descriptor
wallets.

Subject: [PATCH 1282/1725] test/fuzz: Invoke LoadMempool via CChainState

Not only does this increase coverage, it is also more correct in that
when ::LoadMempool is called with a mempool and chainstate, it calls
AcceptToMemoryPool with just the chainstate.

AcceptToMemoryPool will then act on the chainstate's mempool via
CChainState::GetMempool, which may be different from the mempool
originally passed to ::LoadMempool. (In this fuzz test's case, it
definitely is different)

Also, move DummyChainstate to its own file since it's now used by the
validation_load_mempool fuzz test to replace CChainState's m_mempool.

Subject: [PATCH 1283/1725] LoadMempool: Pass in load_path, stop using gArgs

Also:
1. Have CChainState::LoadMempool and ::ThreadImport take in paths and
   pass it through untouched to LoadMempool.
2. Make LoadMempool exit early if the load_path is empty.
3. Adjust the call to ::ThreadImport in ::AppInitMain to correctly pass
   in an empty path if mempool persistence is disabled.

 # - Convenience variables, for example a UNIVALUE_TEST_DIR should not be used
 #     as they interfere with automatic dependency generation
-# - The %reldir% is the relative path from the Makefile.am. This allows
-#   downstreams to use these variables without having to manually account for
-#   the path change.

Subject: [PATCH 1295/1725] wallet: guard and alert about a wallet invalid
 state during chain sync

-Context:
If `AddToWallet` db write fails, the method returns a wtx nullptr without
removing the recently added transaction from the wallet's map.

-Problem:
When a db write error occurs, `AddToWalletIfInvolvingMe` return false even
when the tx is on the wallet's map already --> which makes `SyncTransaction`
skip the `MarkInputsDirty` call --> which leads to a wallet invalid state
where the inputs of this new transaction are not marked dirty, while the
transaction that spends them still exist on the in-memory wallet tx map.

Plus, as we only store arriving transaction inside `AddToWalletIfInvolvingMe`
when we synchronize/scan blocks from the chain and nowhere else, it makes sense
to treat the tx db write error as a runtime error to notify the user about the
problem. Otherwise, the user will lose all the not stored transactions after a
wallet shutdown (without be able to recover them automatically on the next
startup because the chain sync would be above the block where the txs arrived).

Subject: [PATCH 1296/1725] build: Check for std::atomic::exchange rather than
 std::atomic_exchange

Our usage of std::atomic is with it's own exchange function, not
std::atomic_exchange. So we should be looking specifically for that
function.

Additionally, -pthread and -lpthread have an effect on whether -latomic
will be needed, so the atomics check needs to use these flags as well.
This will make the flags in use better match what is actually used when
linking.

This removes the need for -latomic for riscv builds, which resolves a
guix cross architecture reproducibility issue.

Subject: [PATCH 1297/1725] test: add coverage for wallet inconsistent state
 during sync

When a transaction arrives, the wallet mark its inputs (prev-txs) as dirty.
Clearing the wallet transaction cache, triggering a balance recalculation.

If this does not happen due a db write error during `AddToWallet`, the wallet
will be in an invalid state: The transaction that spends certain wallet UTXO will
exist inside the in-memory wallet tx map, having the credit/debit calculated,
while its inputs will still have the old cached data (like if them were never
spent).

Subject: [PATCH 1299/1725] depends: default to using GCC tool wrappers (with
 GCC)

This improves support for LTO by using gcc wrappers for ar, nm, ranlib,
that correctly setup plugin arguments for LTO.

Other HOSTS are using clang.

Subject: [PATCH 1304/1725] interfaces, refactor: Add more block information to
 block connected notifications

Add new interfaces::BlockInfo struct to be able to pass extra block
information (file and undo information) to indexes which they are
updated to use high level interfaces::Chain notifications.

This commit does not change behavior in any way.

Subject: [PATCH 1307/1725] indexes, refactor: Remove CBlockIndex* uses in
 index Init methods

Replace overriden index Init() methods that use the best block
CBlockIndex* pointer with pure CustomInit() callbacks that are passed
the block hash and height.

This gets rid of more CBlockIndex* pointer uses so indexes can work
outside the bitcoin-node process. It also simplifies the initialization
call sequence so index implementations are not responsible for
initializing the base class.

There is a slight change in behavior here since now the best block
pointer is loaded and checked before the custom index init functions are

Subject: [PATCH 1310/1725] indexes, refactor: Remove CChainState use in index
 CommitInternal method

Replace CommitInternal method with CustomCommit and use interfaces::Chain
instead of CChainState to generate block locator.

This commit does not change behavior in any way, except in the
(m_best_block_index == nullptr) case, which was added recently in
https://github.com/bitcoin/bitcoin/pull/24117 as part of an ongoing attempt to
prevent index corruption if bitcoind is interrupted during startup. New
behavior in that case should be slightly better than the old behavior (skipping
the entire custom+base commit now vs only skipping the base commit previously)
and this might avoid more cases of corruption.

Subject: [PATCH 1315/1725] rpc: output wallet descriptors for received entries
 in listsinceblock

The descriptor wallets allow an application to track coins of multiple
descriptors in a single wallet. However, such an application would not
previously be able to (easily) tell what received coin "belongs" to what
descriptor.

This commit tackles this issues by adding a "wallet_desc" entry to the
entries for received coins in 'listsinceblock'.

Subject: [PATCH 1323/1725] refactor: use CoinsResult struct in SelectCoins

Pass the whole CoinsResult struct to SelectCoins instead of only a
vector. This means we now have to remove preselected coins from each
OutputType vector and shuffle each vector individually.

Pass the whole CoinsResult struct to AttemptSelection. This involves
moving the logic in AttemptSelection to a newly named function,
ChooseSelectionResult. This will allow us to run ChooseSelectionResult
over each OutputType in a later commit. This ensures the backoffs work
properly.

Update unit and bench tests to use CoinResult.

Subject: [PATCH 1330/1725] wallet: run coin selection by `OutputType`

Run coin selection on each OutputType separately, choosing the best
solution according to the waste metric.

This is to avoid mixing UTXOs that are of different OutputTypes,
which can hurt privacy.

If no single OutputType can fund the transaction, then coin selection
considers the entire wallet, potentially mixing (current behavior).

This is done inside AttemptSelection so that all OutputTypes are
considered at each back-off in coin selection.

Subject: [PATCH 1331/1725] test: functional test for new coin selection logic

Create a wallet with mixed OutputTypes and send a volley of payments,
ensuring that there are no mixed OutputTypes in the txs. Finally,
verify that OutputTypes are mixed only when necessary.

+"""Test output type mixing during coin selection
+
+A wallet may have different types of UTXOs to choose from during coin selection,
+where output type is one of the following:
+    - BECH32M
+    - BECH32
+    - P2SH-SEGWIT
+    - LEGACY
+
+This test verifies that mixing different output types is avoided unless
+absolutely necessary. Both wallets start with zero funds. Alice mines
+enough blocks to have spendable coinbase outputs. Alice sends three
+random value payments which sum to 10BTC for each output type to Bob,
+for a total of 40BTC in Bob's wallet.
+
+Bob then sends random valued payments back to Alice, some of which need
+unconfirmed change, and we verify that none of these payments contain mixed
+inputs. Finally, Bob sends the remainder of his funds, which requires mixing.
+
+The payment values are random, but chosen such that they sum up to a specified
+total. This ensures we are not relying on specific values for the UTXOs,
+but still know when to expect mixing due to the wallet being close to empty.

have them as the default list in script

Subject: [PATCH 1357/1725] doc: BaseIndex sync behavior with empty datadir

Make a note about a potentially confusing behavior with `BaseIndex::m_synced`;
if the user starts bitcoind with an empty datadir and an index enabled,
BaseIndex will consider itself synced (as a degenerate case). This affects
how indices are built during IBD (relying solely on BlockConnected signals vs.
using ThreadSync()).

+
```

The GetBlockHash() test assertion only passes on master because the different
methods invoked by the current design happen to return the same result.  If one
of the two is changed, it fails like the ToString() assertion does.

Redefining inherited non-virtual functions is well-documented as incorrect
design to avoid inconsistent behavior (see Scott Meyers, "Effective C++", Item
36).  Class usage is confusing when the behavior depends on the pointer
definition instead of the object definition (static binding happening where
dynamic binding was expected).  This can lead to unsuspected or hard-to-track
bugs.

Outside of critical hot spots, correctness usually comes before optimisation,
but the current design dates back to main.cpp and it may possibly have been
chosen to avoid the overhead of dynamic dispatch.  This solution does the same:
the class sizes are unchanged and no vptr or vtbl is added.

There are better designs for doing this that use composition instead of
inheritance or that separate the public interface from the private
implementations.  One example of the latter would be a non-virtual public
interface that calls private virtual implementation methods, i.e. the Template
pattern via the Non-Virtual Interface (NVI) idiom.

Subject: [PATCH 1376/1725] depends: always use correct ar for win qt

If we don't set this explicitly, then qt will still use it's default
windows ar, when building with LTO (when we want it to use gcc-ar).

So set `QMAKE_LIB` which is used for win32, and defaults to `ar -rc`.
This way we always get the correct ar.

Issue can be seen building in Guix with LTO. i.e:
```bash
x86_64-w64-mingw32-ar: .obj/release/hb-blob.o: plugin needed to handle lto object
```

Subject: [PATCH 1387/1725] script: actually trigger the optimization in
 BuildScript

The counter is an optimization over calling `ret.empty()`. It was
suggested that the compiler would realize `cnt` is only `0` on the first
iteration, and not actually emit the check and conditional.

This optimization was actually not triggered at all, since we
incremented `cnt` at the beginning of the first iteration. Fix it by
incrementing at the end instead.

This was reported by Github user "Janus".

Subject: [PATCH 1391/1725] refactor: log `nEvicted` message in `LimitOrphans`
 then return void

`LimitOrphans()` can log expired tx and it should log evicted tx as well
instead of returning the number for caller to print the message.
Since `LimitOrphans()` now return void, the redundant assertion check in
fuzz test is also removed.

Subject: [PATCH 1394/1725] guix: pass enable-bind-now to glibc

Both glibcs we build support `--enable-bind-now`:
Disable lazy binding for installed shared objects and programs.
This provides additional security hardening because it enables full RELRO
and a read-only global offset table (GOT), at the cost of slightly
increased program load times.

Subject: [PATCH 1395/1725] guix: enable hardening options in GCC Build

Pass `--enable-default-pie` and `--enable-default-ssp` when configuring
our GCCs. This achieves the following:

--enable-default-pie
	Turn on -fPIE and -pie by default.

--enable-default-ssp
	Turn on -fstack-protector-strong by default.

Note that this isn't a replacement for passing hardneing flags
ourselves, but introduces some redundency, and there isn't really a
reason to not build a more "hardenings enabled" toolchain by default.

Subject: [PATCH 1396/1725] cctools: fixup building with LTO

Use lto.h from clang+llvm not libtapi. The later is older,
and comes bundled with the libtapi repo.

Copy libLTO.so when building with FORCE_USE_SYSTEM_CLANG.

In AvailableCoins, we need to know whether we can solve for an output.
This was done by using IsSolvable, which just calls ProduceSignature and
produces a dummy signature. However, we already do that in order to get
the size of the input by using CalculateMaximumSignedInputSize. As this
function returns -1 if ProduceSignature fails, we can just remove the
use of IsSolvable and check that input_bytes is not -1 to determine
the solvability of an output.

Subject: [PATCH 1410/1725] bdb: disable Werror for format-security

This is causing build failures in some build environments, like NixOS.
I don't think we are going to patch bdb at this point, and this warning
has existed for as long as we've used bdb.

Fixes #25211.

Tested (in Docker) with:
```bash
docker run -it nixos/nix
nix-shell -p gitMinimal gcc12 libtool pkg-config curl gnumake patch autoconf automake
git clone https://github.com/bitcoin/bitcoin
make -C bitcoin/depends bdb
```

Subject: [PATCH 1412/1725] test: use MiniWallet to simplify
 mempool_package_limits.py tests

Moved `bulk_transaction` into MiniWallet class as `_bulk_tx` private
helper method to be used when the newly added `target_weight` option is
passed to `create_self_transfer*`

Subject: [PATCH 1413/1725] test: MiniWallet: add `send_self_transfer_chain` to
 create chain of txns

With this new method, a chain of transactions can be created. This
method is introduced to further simplify the mempool_package_limits.py
tests.

 **Policy** (Mempool or Transaction Relay Policy) is the node's set of validation rules, in addition
 to consensus, enforced for unconfirmed transactions before submitting them to the mempool. These
 rules are local to the node and configurable (e.g. `-minrelaytxfee`, `-limitancestorsize`,
-`-incrementalRelayFee`). Policy may include restrictions on the transaction itself, the transaction
+`-incrementalrelayfee`). Policy may include restrictions on the transaction itself, the transaction
 in relation to the current chain tip, and the transaction in relation to the node's mempool
 contents. Policy is *not* applied to transactions in blocks.

lib, as it will be pruned of ArgsManager.

Subject: [PATCH 1432/1725] refactor: Replace BResult with util::Result

Rename `BResult` class to `util::Result` and update the class interface to be
more compatible with `std::optional` and with a full-featured result class
implemented in https://github.com/bitcoin/bitcoin/pull/25665. Motivation for
this change is to update existing `BResult` usages now so they don't have to
change later when more features are added in #25665.

This change makes the following improvements originally implemented in #25665:

- More explicit API. Drops potentially misleading `BResult` constructor that
  treats any bilingual string argument as an error. Adds `util::Error`
  constructor so it is never ambiguous when a result is being assigned an error
  or non-error value.

- Better type compatibility. Supports `util::Result<bilingual_str>` return
  values to hold translated messages which are not errors.

- More standard and consistent API. `util::Result` supports most of the same
  operators and methods as `std::optional`. `BResult` had a less familiar
  interface with `HasRes`/`GetObj`/`ReleaseObj` methods. The Result/Res/Obj
  naming was also not internally consistent.

- Better code organization. Puts `src/util/` code in the `util::` namespace so
  naming reflects code organization and it is obvious where the class is coming
  from. Drops "B" from name because it is undocumented what it stands for
  (bilingual?)

- Has unit tests.

+//! The util::Result class provides a standard way for functions to return

+//!
+//! It is intended for high-level functions that need to report error strings to
+//! end users. Lower-level functions that don't need this error-reporting and
+//! only need error-handling should avoid util::Result and instead use standard
+//! classes like std::optional, std::variant, and std::tuple, or custom structs
+//! and enum types to return function results.
+//!
+//! Usage examples can be found in \example ../test/result_tests.cpp, but in
+//! general code returning `util::Result<T>` values is very similar to code
+//! returning `std::optional<T>` values. Existing functions returning
+//! `std::optional<T>` can be updated to return `util::Result<T>` and return
+//! error strings usually just replacing `return std::nullopt;` with `return
+//! util::Error{error_string};`.

Subject: [PATCH 1433/1725] scripted-diff: remove mention of BIP125 from
 non-signaling var names

Our RBF policy is different from the rules specified in BIP125 (refer to
doc/policy/mempool-replacements.md instead), and will continue to
diverge with package RBF.  Keep references to BIP125 sequence number,
since that is still useful and correct.

-BEGIN VERIFY SCRIPT-
ren() { sed -i "s:\<$1\>:$2:g" $(git grep -l "\<$1\>" ./src ./test); }

ren m_allow_bip125_replacement m_allow_replacement
ren allow_bip125_replacement allow_replacement
ren MAX_BIP125_REPLACEMENT_CANDIDATES MAX_REPLACEMENT_CANDIDATES

Subject: [PATCH 1435/1725] tests: Reduce calls to InitS*Cache()

In src/test/fuzz/script_sigcache.cpp, we should really be setting up a
full working BasicTestingSetup. The initialize_ function is only run
once anyway.

In src/test/txvalidationcache_tests.cpp, the Dersig100Setup inherits
from BasicTestingSetup, which should have already set up a global script
execution cache without the need to explicitly call
InitScriptExecutionCache.

Subject: [PATCH 1437/1725] validationcaches: Abolish arbitrary limit

1. -maxsigcachesize is a DEBUG_ONLY option

2. Almost 7 years has passed since its semantics change in
   830e3f3d027ba5c8121eed0f6a9ce99961352572 from "number of entries" to
   "number of mebibytes"

3. A std::new_handler was added to the codebase after the original PR
   which introduced this limit, which will terminate immediately instead
   of causing trouble by being caught somewhere unexpected.

Subject: [PATCH 1438/1725] cuckoocache: Check for uint32 overflow in
 setup_bytes

This fixes an potential overflow which existed prior to this patchset.

If CuckooCache::cache<Element, Hash>::setup_bytes is called with a
`size_t bytes` which, when divided by sizeof(Element), does not fit into
an uint32_t, the implicit conversion to uint32_t in the call to setup
will result in an overflow.

At least on x86_64, this overflow is possible:

static_assert(std::numeric_limits<size_t>::max() / 32 <= std::numeric_limits<uint32_t>::max());
static_assert(std::numeric_limits<size_t>::max() / 4 <= std::numeric_limits<uint32_t>::max());

This commit detects such cases and signals to callers that the `size_t
bytes` input is too large.

Subject: [PATCH 1439/1725] validationcaches: Add and use ValidationCacheSizes

Also:

- Make DEFAULT_MAX_SIG_CACHE_SIZE into constexpr
  DEFAULT_MAX_SIG_CACHE_BYTES to utilize the compile-time integer
  arithmetic overflow checking available to constexpr.
- Fix comment (MiB instead of MB) for DEFAULT_MAX_SIG_CACHE_BYTES.
- Pass in max_size_bytes parameter to InitS*Cache(), modify log line to
  no longer allude to maxsigcachesize being split evenly between the two
  validation caches.
- Fix possible integer truncation and add a comment.

[META] I've kept the integer types as int64_t in order to not introduce
       unintended behaviour changes, in the next commit we will make
       them size_t.

Subject: [PATCH 1443/1725] Change getWalletTxs to return a set instead of a
 vector

For some reason, the primary consumer of getWalletTxs requires the
transactions to be in hash order when it is processing them. std::map
will iterate in hash order so the transactions end up in that order when
placed into the vector. To ensure this order when mapWallet is no longer
ordered, the vector is replaced with a set which will maintain the hash
order.

Subject: [PATCH 1450/1725] [doc] remove non-signaling mentions of BIP125

Our RBF policy is different from the rules specified in BIP125. For
example, the BIP does not mention Rule 6, and our Rule 4 uses the
(configurable) incremental relay feerate (distinct from the
minimum relay feerate). Those interested in our policy should refer to
doc/policy/mempool-replacements.md instead. These rules may also
continue to diverge with package RBF and other RBF improvements. Keep
references to the BIP125 signaling wrt sequence numbers, since that is
still correct and widely used. It is helpful to refer to this as "BIP125
signaling" since it is unambiguous and succint, especially if we have
multiple ways to signal replaceability in the future.

The rule numbers in doc/policy/mempool-replacements.md correspond
largely to those of BIP 125, so we can still refer to them like "Rule 5."

Subject: [PATCH 1451/1725] rpc/wallet: add simulaterawtransaction RPC

This command iterates over the inputs and outputs of the given transactions, and tallies up the balance change for the given wallet. This can be useful e.g. when verifying that a coin join like transaction doesn't contain unexpected inputs that the wallet will then sign for unintentionally.

Subject: [PATCH 1459/1725] guix: patch NSIS to remove .reloc sections from
 install stubs

With the release of binutils/ld 2.36, ld swapped to much improved
default settings when producing windows binaries with mingw-w64. One of
these changes was to stop stripping the .reloc section from binaries,
which is required for working ASLR.

.reloc section stripping is something we've accounted for previously,
see #18702. The related upstream discussion is in this thread:
https://sourceware.org/bugzilla/show_bug.cgi?id=19011.

When we switched to using a newer Guix time-machine in #23778, we begun
using binutils 2.37 to produce releases. Since then, our windows
installer (produced with makensis) has not functioned correctly when run on
a Windows system with the "Force randomization for images (Mandatory ASLR)"
option enabled. Note that all of our other release binaries, which all
contain .reloc sections, function fine under the same option, so it
cannot be just the presence of a .reloc section that is the issue.

For now, restore makensis to it's pre-binutils-2.36 behaviour, which
fixes the produced installer. The underlying issue can be further
investigated in future.

+Patch NSIS so that it's installer stubs, produced at NSIS build time,
+do not contain .reloc sections, which will exist by default when using
+binutils/ld 2.36+.
+
+This ultimately fixes an issue when running the installer with the
+"Force randomization for images (Mandatory ASLR)" setting active.
+
+This patch has not yet been sent upstream, because it's not clear if this
+is the best fix, for the underlying issue, which seems to be that makensis
+doesn't account for .reloc sections when it builds installers.
+
+The existence of a reloc section shouldn't be a problem, and, if anything,
+is actually a requirement for working ASLR. All other Windows binaries we
+produce contain them, and function correctly when under the same
+"Force randomization for images (Mandatory ASLR)" setting.

Subject: [PATCH 1475/1725] build: move raw rule into Makefile.am

The same rule is used by the tests and benchmarks to generate headers,
and currently causes #25501. Just deduplicate the code into Makefile.am.

Subject: [PATCH 1476/1725] net: simplify GetLocalAddress()

There is no need to use two variables `ret` and `addr` of the same type
`CService` and assign one to the other in a strange way like
`ret = CService{addr}`.

Subject: [PATCH 1479/1725] wallet: switch to new shuffle, erase, push_back

switch to new methods, remove old code. this also
updates the Size, All, and Clear methods to now use
the coins map.

this commit is not strictly a refactor because previously
coin selection was never run over the UNKNOWN type until the last
step when being run over all. now that we are iterating over each,
it is run over UNKNOWN but this is expected to be empty most of the time.

Subject: [PATCH 1482/1725] refactor: improve readability for AttemptSelection

it was pointed out by a few reviewers that the code block at the end
of attempt selection was difficult to follow and lacked comments.

refactor to get rid of triple nested if statement and improve
readibility.

Subject: [PATCH 1484/1725] validation tests: Use existing
 {Chainstate,Block}Man

Use {Chain,}TestingSetup's existing {Chainstate,Block}Manager and avoid
unnecessarily creating a local one.

This also helps reduce the code diff for a later commit where we change
{Chainstate,Block}Manager's constructor signature.

Subject: [PATCH 1487/1725] [test] make tx6 child of tx5, not tx3, in rbf_tests

There is no effect on the test results because tx3 and tx5 pay the say
fee, but this was the intended configuration, as the comment suggests.

Subject: [PATCH 1491/1725] i2p: add support for creating transient sessions

Instead of providing our destination (private key) to the I2P proxy when
creating the session, ask it to generate one for us and do not save it
on disk.

Subject: [PATCH 1495/1725] GUI: sendCoinsDialog, remove duplicate
 wallet().getBalances() call

Inside setModel, we call 'wallet().getBalances()', to set the view balance,
right before calling 'updateDisplayUnit' which calls 'wallet().getBalances()'
internally and re-sets the view balance again.

Subject: [PATCH 1497/1725] GUI: use cached balance in overviewpage and
 sendcoinsdialog

Plus, calculate the cached balance right when the wallet model, so the wallet widgets don't need to redo the same balance calculation multiple times when they are waiting for the model balance polling timer.

----------------------------------------------------------------------

test wise: `WalletTests` now need to trigger the walletModel balance changed manually. So the model updates its internal state and can be used by the widgets.

This is because the test does not start the balance polling timer, in the same way as does not initialize several parts of the GUI workflow. All the objects (wallet, models, views, etc) that are used on this test are manually created instead of using the `WalletController` class flow.

Rationale is that this unit test is focused on verifying the GUI widgets/views behavior only: update the presented information, etc. when they receive different signals and/or function calls from outside (in other words, focus is on the signal slots/receiver side). It's not about whether the wallet balance polling timer is functioning as expected or not (which we definitely create a new test case for it in a follow-up work).

Subject: [PATCH 1500/1725] Reduce bandwidth during initial headers sync when a
 block is found

If our headers chain is behind on startup, then if a block is found we'll try
to catch up from all peers announcing the block, in addition to our initial
headers-sync peer. This commit changes behavior so that in this situation,
we'll choose at most one peer announcing a block to additionally sync headers
from.

Subject: [PATCH 1508/1725] wallet: accurate SelectionResult::m_target

SelectionResult::m_target should be equal to actual selection target.
Selection target is the sum of all recipient amounts plus non input fees.
So we need to remove change_fee from the m_target. It's safe because change
target is always greater than the change fee, so we can always cover fees
if change output is created.

Subject: [PATCH 1510/1725] wallet: account for preselected inputs in target

When we have preselected inputs the coin selection search target is reduced
by the sum of (effective) values. This causes incorrect m_target value.

Create separate instance of SelectionResult for all the preselected inputs and
set the target equal to the sum of (effective) values. Target for preselected
SelectionResult is equal to the delta for the search target. To get the final
SelectionResult with accurate m_target we merge both SelectionResult instances.

Subject: [PATCH 1522/1725] net: store an optional I2P session in CNode

and destroy it when `CNode::m_sock` is closed.

I2P transient sessions are created per connection (i.e. per `CNode`) and
should be destroyed when the connection is closed. Storing the session
in `CNode` is a convenient way to destroy it together with the connection
socket (`CNode::m_sock`).

An alternative approach would be to store a list of all I2P sessions in
`CConnman` and from `CNode::CloseSocketDisconnect()` to somehow ask the
`CConnman` to destroy the relevant session.

If not accepting I2P connections, then do not create

When opening a new outbound I2P connection either use
`CConnman::m_i2p_sam_session` like before or create a temporary one and
store it in `CNode` for destruction later.

Subject: [PATCH 1524/1725] test: add a test that -i2pacceptincoming=0 creates
 a transient session

The test is a bit primitive as it checks the Bitcoin Core log and
assumes that if it logs that it creates a transient session, then it
does that indeed.

A more thorough test would be to check that it indeed sends the
`SESSION CREATE ... DESTINATION=TRANSIENT` command and that it uses
the returned I2P address for connecting, even for repeated connections
to the same I2P peer. That would require a mocked SAM server (proxy)
implementation in Python.

Subject: [PATCH 1529/1725] Fix UB/data-race in RPCNotifyBlockChange

ActiveTip() is *not* thread-safe, as the required ::cs_main lock will be
released as ActiveChainstate() returns.

ActiveTip() is an alias for ActiveChainstate().m_chain.Tip(), so m_chain
may be involved in a data-race (UB).

Subject: [PATCH 1530/1725] Fix logical race in rest_getutxos

Calling ActiveHeight() and ActiveTip() subsequently without holding the
::cs_main lock over both calls may result in a height that does not
correspond to the tip due to a race.

Fix this by holding the lock.

Subject: [PATCH 1531/1725] refactor: Add lock annotations to Active* methods

This is a refactor, putting the burden to think about thread safety to
the caller. Otherwise, there is a risk that the caller will assume
thread safety where none exists, as is evident in the previous two
commits.

Subject: [PATCH 1532/1725] rpc: add an include_change parameter to
 listsinceblock

It's useful for an external application tracking coins to not be limited
by our change detection. For instance, for a watchonly wallet with two
descriptors a transaction from one to the other would be considered a
change output and not be included in the result (if the address was not
generated by this wallet).

Subject: [PATCH 1537/1725] Simplify BCLog::Level enum class and
 LogLevelToStr() function

- simplify the BCLog::Level enum class (and future changes to it) by
  only setting the value of the first enumerator

- move the BCLog::Level:None enumerator to the end of the BCLog::Level
  enum class and LogLevelToStr() member function, as the None enumerator
  is only used internally, and by being the highest BCLog::Level value it
  can be used to iterate over the enumerators

- replace the unused BCLog::Level:None string "none" with an empty string
  as the case will never be hit

- add documentation

Subject: [PATCH 1542/1725] fs: work around u8path deprecated-declaration
 warnings with libc++

When building in c++20 mode using libc++, the following warning is
emitted:
```bash

    return std::filesystem::u8path(utf8_str);

1 warning generated.
```

as u8path<std::string> is deprecated starting with c++20.

Fixes: #24682.

Subject: [PATCH 1544/1725] bumpfee: extract weights of external inputs when
 bumping fee

When bumping the fee of a transaction containing external inputs,
determine the weights of those inputs. Because signatures can have a
variable size, the script is executed with a special SignatureChecker
which will compute the total weight of the signatures in the transaction
and the weight if they were all maximum size signatures. This allows us
to compute the maximum weight of the input for use during coin
selection.

Subject: [PATCH 1545/1725] bumpfee: Clear scriptSigs and scriptWitnesses
 before calculated max size

The max size calculation expects some inputs to have empty scriptSigs
and witnesses, so we need to clear these before doing that calculation.

Subject: [PATCH 1546/1725] bumpfee: be able to bump fee of a tx with external
 inputs

In some cases, notably psbtbumpfee, it is okay, and potentially desired,
to be able to bump the fee of a transaction which contains external
inputs.

 Changes to the configuration file while `bitcoind` or `bitcoin-qt` is running only take effect after restarting.
 
+Users should never make any configuration changes which they do not understand. Furthermore, users should always be wary of accepting any configuration changes provided to them by another source (even if they believe that they do understand them).
+
 ## Configuration File Format
 
 The configuration file is a plain text file and consists of `option=value` entries, one per line. Leading and trailing whitespaces are removed.

Subject: [PATCH 1561/1725] Create -loglevel configuration option

- add a -loglevel=<level>|<category:level> config option to allow users
  to set a global -loglevel and category-specific log levels. LogPrintLevel
  messages with a higher severity level than -loglevel will not be printed
  in the debug log.

- for now, this config option is debug-only during the migration to
  severity-based logging

- update unit and functional tests

Subject: [PATCH 1563/1725] Create BCLog::Level::Trace log severity level

for verbose log messages for development or debugging only, as bitcoind may run
more slowly, that are more granular/frequent than the Debug log level, i.e. for
very high-frequency, low-level messages to be logged distinctly from
higher-level, less-frequent debug logging that could still be usable in production.

An example would be to log higher-level peer events (connection, disconnection,
misbehavior, eviction) as Debug, versus Trace for low-level, high-volume p2p
messages in the BCLog::NET category. This will enable the user to log only the
former without the latter, in order to focus on high-level peer management events.

With respect to the name, "trace" is suggested as the most granular level
in resources like the following:
- https://sematext.com/blog/logging-levels
- https://howtodoinjava.com/log4j2/logging-levels

Update the test framework and add test coverage.

 If the code is behaving strangely, take a look in the `debug.log` file in the data directory;
 error and debugging messages are written there.
 
-The `-debug=...` command-line option controls debugging; running with just `-debug` or `-debug=1` will turn
-on all categories (and give you a very large `debug.log` file).
+Debug logging can be enabled on startup with the `-debug` and `-loglevel`
+configuration options and toggled while bitcoind is running with the `logging`
+RPC.  For instance, launching bitcoind with `-debug` or `-debug=1` will turn on
+all log categories and `-loglevel=trace` will turn on all log severity levels.
 
 The Qt code routes `qDebug()` output to `debug.log` under category "qt": run with `-debug=qt`
 to see it.

Subject: [PATCH 1567/1725] init: avoid unsetting service bits from
 `nLocalServices`

Rather than setting the service bit `NODE_NETWORK` first and then unset
it, start out the bare minimum flags that every node serves and only add
`NODE_NETWORK` if we are running as a non-pruned node.

Subject: [PATCH 1570/1725] refactor: Move ChainstateManager options into
 m_options struct

Move ChainstateManager options into m_options struct to simplify class
initialization, organize class members, and to name external option variables
differently than internal state variables.

This change was originally in #25862, but it was suggested to split off in
https://github.com/bitcoin/bitcoin/pull/25862#discussion_r951459817 so it could
be merged earlier and reduce conflicts with other PRs.

Subject: [PATCH 1571/1725] Add function to validate difficulty changes

The rule against difficulty adjustments changing by more than a factor of 4 can
be helpful for anti-DoS measures in contexts where we lack a full headers
chain, so expose this functionality separately and in the narrow case where we
only know the height, new value, and old value.

Includes fuzz test by Martin Zumsande.

Subject: [PATCH 1573/1725] Add functions to construct locators without CChain

This introduces an insignificant performance penalty, as it means locator
construction needs to use the skiplist-based CBlockIndex::GetAncestor()
function instead of the lookup-based CChain, but avoids the need for
callers to have access to a relevant CChain object.

Subject: [PATCH 1587/1725] wallet: trigger MaybeResendWalletTxs() every minute

ResendWalletTransactions() only executes every 12-36h (24h average).
Triggering it every second is excessive, once per minute should be
plenty.

Refactors SetupDescSPKMs so that the DescSPKM loops are in their own
function. This allows us to call it later during migration with a key

Subject: [PATCH 1598/1725] Utilize anti-DoS headers download strategy

Avoid permanently storing headers from a peer, unless the headers are part of a
chain with sufficiently high work. This prevents memory attacks using low-work
headers.

Designed and co-authored with Pieter Wuille.

+/** HeadersSyncState:
+ *
+ * We wish to download a peer's headers chain in a DoS-resistant way.
+ *
+ * The Bitcoin protocol does not offer an easy way to determine the work on a
+ * peer's chain. Currently, we can query a peer's headers by using a GETHEADERS
+ * message, and our peer can return a set of up to 2000 headers that connect to
+ * something we know. If a peer's chain has more than 2000 blocks, then we need
+ * a way to verify that the chain actually has enough work on it to be useful to
+ * us -- by being above our anti-DoS minimum-chain-work threshold -- before we
+ * commit to storing those headers in memory. Otherwise, it would be cheap for
+ * an attacker to waste all our memory by serving us low-work headers
+ * (particularly for a new node coming online for the first time).
+ *
+ * To prevent memory-DoS with low-work headers, while still always being
+ * able to reorg to whatever the most-work chain is, we require that a chain
+ * meet a work threshold before committing it to memory. We can do this by
+ * downloading a peer's headers twice, whenever we are not sure that the chain
+ * has sufficient work:
+ *
+ * - In the first download phase, called pre-synchronization, we can calculate
+ * the work on the chain as we go (just by checking the nBits value on each
+ * header, and validating the proof-of-work).
+ *
+ * - Once we have reached a header where the cumulative chain work is
+ * sufficient, we switch to downloading the headers a second time, this time
+ * processing them fully, and possibly storing them in memory.
+ *
+ * To prevent an attacker from using (eg) the honest chain to convince us that
+ * they have a high-work chain, but then feeding us an alternate set of
+ * low-difficulty headers in the second phase, we store commitments to the
+ * chain we see in the first download phase that we check in the second phase,
+ * as follows:
+ *
+ * - In phase 1 (presync), store 1 bit (using a salted hash function) for every
+ * N headers that we see. With a reasonable choice of N, this uses relatively
+ * little memory even for a very long chain.
+ *
+ * - In phase 2 (redownload), keep a lookahead buffer and only accept headers
+ * from that buffer into the block index (permanent memory usage) once they
+ * have some target number of verified commitments on top of them. With this
+ * parametrization, we can achieve a given security target for potential
+ * permanent memory usage, while choosing N to minimize memory use during the
+ * sync (temporary, per-peer storage).

Subject: [PATCH 1599/1725] Require callers of AcceptBlockHeader() to perform
 anti-dos checks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In order to prevent memory DoS, we must ensure that we don't accept a new
header into memory until we've performed anti-DoS checks, such as verifying
that the header is part of a sufficiently high work chain. This commit adds a
new argument to AcceptBlockHeader() so that we can ensure that all call-sites
which might cause a new header to be accepted into memory have to grapple with
the question of whether the header is safe to accept, or needs further
validation.

This patch also fixes two places where low-difficulty-headers could have been
processed without such validation (processing an unrequested block from the
network, and processing a compact block).

Credit to Niklas Gögge for noticing this issue, and thanks to Sjors Provoost
for test code.

Subject: [PATCH 1600/1725] Reduce spurious messages during headers sync

Delay sending SENDHEADERS (BIP 130) message until we know our peer's best
header's chain has more than nMinimumChainWork. This reduces inadvertent
headers messages received during initial headers sync due to block
announcements, which throw off our sync algorithm.

Subject: [PATCH 1606/1725] Make validation interface capable of signalling
 header presync

This makes a number of changes:
- Get rid of the verification_progress argument in the node interface
  NotifyHeaderTip (it was always 0.0).
- Instead of passing a CBlockIndex* in the UI interface's NotifyHeaderTip,
  send separate height, timestamp fields. This is becuase in headers presync,
  no actual CBlockIndex object is available.
- Add a bool presync argument to both of the above, to identify signals
  pertaining to the first headers sync phase.

Subject: [PATCH 1610/1725] net: mark TransportSerializer/m_serializer as const

The (V1)TransportSerializer instance CNode::m_serializer is used from
multiple threads via PushMessage without protection by a mutex. This
is only thread safe because the class does not have any mutable state,
so document that by marking the methods and the object as "const".

Subject: [PATCH 1611/1725] net: mark CNode unique_ptr members as const

Dereferencing a unique_ptr is not necessarily thread safe. The reason
these are safe is because their values are set at construction and do
not change later; so mark them as const and set them via the initializer
list to guarantee that.

Subject: [PATCH 1612/1725] net: note CNode members that are treated as const

m_permissionFlags and m_prefer_evict are treated as const -- they're
only set immediately after construction before any other thread has
access to the object, and not changed again afterwards. As such they
don't need to be marked atomic or guarded by a mutex; though it would
probably be better to actually mark them as const...

Subject: [PATCH 1613/1725] wallet: Deduplicate Resend and
 ReacceptWalletTransactions

Both of these functions do almost the exact same thing. They can be
deduplicated so that their behavior matches except for the filtering
aspect. As this function will now always be called on wallet loading,
nNextResend will also always be initialized, so
wallet_resendwallettransactions.py is updated to account for that.

This also resolves a bug where ResendWalletTransactions would fail to
rebroadcast txs in insertion order thereby potentially rebroadcasting a
child transaction before its parent and causing the child to not
actually get rebroadcast.

Also names the combined function to ResubmitWalletTransactions as the
function just submits the transactions to the mempool rather than doing
any sending by itself.

Subject: [PATCH 1614/1725] test: Test that an unconfirmed not-in-mempool chain
 is rebroadcast

The test checks that parent txs are broadcast before child txs.

The previous behavior is that the rebroadcasting would simply iterate mapWallet. As
mapWallet is a std::unsorted_map, the child can sometimes come before the parent and thus
be rebroadcast in the wrong order and fail the test.

+## Migrating Legacy Wallets to Descriptor Wallets
+
+Legacy wallets (traditional non-descriptor wallets) can be migrated to become Descriptor wallets
+through the use of the `migratewallet` RPC. Migrated wallets will have all of their addresses and private keys added to
+a newly created Descriptor wallet that has the same name as the original wallet. Because Descriptor
+wallets do not support having private keys and watch-only scripts, there may be up to two
+additional wallets created after migration. In addition to a descriptor wallet of the same name,
+there may also be a wallet named `<name>_watchonly` and `<name>_solvables`. `<name>_watchonly`
+contains all of the watchonly scripts. `<name>_solvables` contains any scripts which the wallet
+knows but is not watching the corresponding P2(W)SH scripts.
+
+Migrated wallets will also generate new addresses differently. While the same BIP 32 seed will be
+used, the BIP 44, 49, 84, and 86 standard derivation paths will be used. After migrating, a new
+backup of the wallet(s) will need to be created.
+
+Given that there is an extremely large number of possible configurations for the scripts that
+Legacy wallets can know about, be watching for, and be able to sign for, `migratewallet` only
+makes a best effort attempt to capture all of these things into Descriptor wallets. There may be
+unforeseen configurations which result in some scripts being excluded. If a migration fails
+unexpectedly or otherwise misses any scripts, please create an issue on GitHub. A backup of the
+original wallet can be found in the wallet directory with the name `<name>-<timestamp>.legacy.bak`.
+
+The backup can be restored using the `restorewallet` command as discussed in the
+[Restoring the Wallet From a Backup](#16-restoring-the-wallet-from-a-backup) section

+Migrating Legacy Wallets to Descriptor Wallets
+---------------------------------------------
+
+An experimental RPC `migratewallet` has been added to migrate Legacy (non-descriptor) wallets to
+Descriptor wallets. More information about the migration process is available in the
+[documentation](https://github.com/bitcoin/bitcoin/blob/master/doc/managing-wallets.md#migrating-legacy-wallets-to-descriptor-wallets).

Subject: [PATCH 1643/1725] test: apply fixed feerate to avoid variable dynamic
 fees

Without specifying a feerate, we let the wallet decide on an
appropriate feerate, which can be influenced by various factors
such as what's in the mempool. Since wallet_groups.py fails when
feerates are unstable, we should use a fixed feerate across all nodes.

Closes #25940

Subject: [PATCH 1646/1725] message-capture-parser: fix AssertionError on
 parsing `headers` message

If a test framework message's field name is in the list of
`HASH_INT_VECTORS`, we currently assume that it _always_ has to contain
a vector of integers and throw otherwise (introduced in PR #25367,
commit 42bbbba7c83d1e2baad18b4c6f05bad1358eb117). However, that
assumption is too strict. In this concrete case, the (de)serialization
field name "headers" is used in two different message types, one for
`cfcheckpt` (where it is serialized as an integer vector), and another
time for `headers` (where it is serialized as a vector of
`CBlockHeader`s). Fix by adding the integer type check as additional
condition to the `HASH_INT_VECTORS` check rather than asserting.
Fixes #25954.

Subject: [PATCH 1649/1725] init: allow startup with -onlynet=onion
 -listenonion=1

It does not make sense to specify `-onlynet=onion` without providing a
Tor proxy (even if other `-onlynet=...` are given). This is checked
during startup. However, it was forgotten that a Tor proxy can also be
retrieved from "Tor control" to which we connect if `-listenonion=1`.

So, the full Tor proxy retrieval logic is:
1. get it from `-onion`
2. get it from `-proxy`
3. if `-listenonion=1`, then connect to "Tor control" and get the proxy
   from there (was forgotten before this change)

Fixes https://github.com/bitcoin/bitcoin/issues/24980

Subject: [PATCH 1650/1725] guix: consistently use -ffile-prefix-map

Aside from being the newer, more comprehensive option, it's what we
claim to use in the patch docs, and everywhere else in guix.

Subject: [PATCH 1651/1725] p2p: add only reachable addresses to addrman

We will not make outgoing connection to peers that are unreachable
(e.g. because of -onlynet configuration).
Therefore, it makes no sense to add them to addrman in the first place.
While this is already the case for addresses received via p2p addr
messages, this commit does the same for addresses received
from fixed seeds.

Subject: [PATCH 1652/1725] p2p: Don't query DNS seeds when both IPv4 and IPv6
 are unreachable

This happens, for example, if the user specified -onlynet=onion or
-onlynet=i2p. DNS seeds only resolve to IPv4 / IPv6 addresses,
making their answers useless to us, since we don't want to make
connections to these.
If, within the DNS seed thread, we'd instead do fallback AddrFetch
connections to one of the clearnet addresses the DNS seed resolves to,
we might get usable addresses from other networks
if lucky, but would be violating our -onlynet user preference
in doing so.

Therefore, in this case it is better to rely on fixed seeds for networks we
want to connect to.

Subject: [PATCH 1657/1725] guix: use git-minimal over git

From the git-minimal package definition:
> The size of the closure of 'git-minimal' is two thirds that of 'git'.
> Its test suite runs slightly faster and most importantly it doesn't
> depend on packages that are expensive to build such as Subversion.

We don't need any fancy / additional git functionality above the basics,
so switch to git-minimal and save some CPU, while also pruning the
greater dependency graph.

Subject: [PATCH 1665/1725] wallet: bugfix, load wallet with an unknown
 descriptor cause fatal error

If the descriptor entry is unrecognized/corrupt, the unserialization fails and
`LoadWallet` instead of stop there and return the error, continues reading all
the db records. As other records tied to the unrecognized/corrupted descriptor
are scanned, a fatal error is thrown.

Subject: [PATCH 1676/1725] RPC: bugfix, 'add_inputs' default value is true
 unless 'inputs' are provided

In both RPC commands `send()` and `walletcreatefundedpsbt` the RPC help was saying
that `add_inputs` default value was false when it's actually dynamically set
by the following statement:

`coin_control.m_allow_other_inputs = rawTx.vin.size() == 0;`

Which means that, by default, `add_inputs` is true unless there
was any pre-set input, in which case, the default is false.

Subject: [PATCH 1685/1725] test: add coverage for 'add_inputs' dynamic default
 value

Covered cases for send() and walletcreatefundedpsbt() RPC commands:

1. Default add_inputs value with no preset inputs (add_inputs=true):
       Expect: automatically add coins from the wallet to the tx.

2. Default add_inputs value with preset inputs (add_inputs=false):
       Expect: disallow automatic coin selection.

3. Explicit add_inputs=true and preset inputs (with preset inputs not-covering the target amount).
       Expect: include inputs from the wallet.

4. Explicit add_inputs=true and preset inputs (with preset inputs covering the target amount).
       Expect: only preset inputs are used.

5. Explicit add_inputs=true, no preset inputs (same as (1) but with an explicit set):
       Expect: include inputs from the wallet.

Subject: [PATCH 1687/1725] build: remove unused natpmp / upnp cppflags

Their inclusion is likely just the result of copy-paste.

The only place upnp/natpmpflags  should be used is `libbitcoin_node`
(mapport.cpp).

Subject: [PATCH 1689/1725] wallet: fix sendall creates tx that fails tx-size
 check

The `sendall` RPC doesn't use `CreateTransactionInternal`as the rest of
the wallet RPCs and it never checks against the tx-size mempool limit.
Add a check for tx-size as well as test coverage for that case.

-GUI changes
------------
-
-Configuration changes made in the bitcoin GUI (such as the pruning setting,
-proxy settings, UPNP preferences) are now saved to `<datadir>/settings.json`
-file rather than to the Qt settings backend (windows registry or unix desktop
-config files), so these settings will now apply to bitcoind, instead of being
-ignored.
-
-Also, the interaction between GUI settings and `bitcoin.conf` settings is
-simplified. Settings from `bitcoin.conf` are now displayed normally in the GUI
-settings dialog, instead of in a separate warning message ("Options set in this
-dialog are overridden by the configuration file: -setting=value"). And these
-settings can now be edited because `settings.json` values take precedence over
-`bitcoin.conf` values.

-Migrating Legacy Wallets to Descriptor Wallets
----------------------------------------------
-
-An experimental RPC `migratewallet` has been added to migrate Legacy (non-descriptor) wallets to
-Descriptor wallets. More information about the migration process is available in the
-[documentation](https://github.com/bitcoin/bitcoin/blob/master/doc/managing-wallets.md#migrating-legacy-wallets-to-descriptor-wallets).

-
-*version* Release Notes Draft
-===============================
-
-Bitcoin Core version *version* is now available from:
-
-  <https://bitcoincore.org/bin/bitcoin-core-*version*/>
-
-This release includes new features, various bug fixes and performance
-improvements, as well as updated translations.
-
-Please report bugs using the issue tracker at GitHub:
-
-  <https://github.com/bitcoin/bitcoin/issues>
-
-To receive security and update notifications, please subscribe to:
-
-  <https://bitcoincore.org/en/list/announcements/join/>
-
-How to Upgrade
-==============
-
-If you are running an older version, shut it down. Wait until it has completely
-shut down (which might take a few minutes in some cases), then run the
-installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on Mac)
-or `bitcoind`/`bitcoin-qt` (on Linux).
-
-Upgrading directly from a version of Bitcoin Core that has reached its EOL is
-possible, but it might take some time if the data directory needs to be migrated. Old
-wallet versions of Bitcoin Core are generally supported.
-
-Compatibility
-==============
-
-Bitcoin Core is supported and extensively tested on operating systems
-using the Linux kernel, macOS 10.15+, and Windows 7 and newer.  Bitcoin
-Core should also work on most other Unix-like systems but is not as
-frequently tested on them.  It is not recommended to use Bitcoin Core on
-unsupported systems.

-Notable changes

-P2P and network changes
------------------------
-
-Updated RPCs
-------------
-
-- The `-deprecatedrpc=softforks` configuration option has been removed.  The
-  RPC `getblockchaininfo` no longer returns the `softforks` field, which was
-  previously deprecated in 23.0. (#23508) Information on soft fork status is
-  now only available via the `getdeploymentinfo` RPC.
-
-- The `deprecatedrpc=exclude_coinbase` configuration option has been removed.
-  The `receivedby` RPCs (`listreceivedbyaddress`, `listreceivedbylabel`,
-  `getreceivedbyaddress` and `getreceivedbylabel`) now always return results
-  accounting for received coins from coinbase outputs, without an option to
-  change that behaviour. Excluding coinbases was previously deprecated in 23.0.
-  (#25171)
-
-- The `deprecatedrpc=fees` configuration option has been removed. The top-level
-  fee fields `fee`, `modifiedfee`, `ancestorfees` and `descendantfees` are no
-  longer returned by RPCs `getmempoolentry`, `getrawmempool(verbose=true)`,
-  `getmempoolancestors(verbose=true)` and `getmempooldescendants(verbose=true)`.
-  The same fee fields can be accessed through the `fees` object in the result.
-  The top-level fee fields were previously deprecated in 23.0. (#25204)

Subject: [PATCH 1699/1725] fix errors from merge of bitcoin/bitcoin#23083

Notes:
- bitcoin/bitcoin#23083 increassed how stict the RPC documentation type checks are
- I initially tried fixing all the types -- you can see that work in this commit.
- In the end, I decided there were way too many discrepencies and that it would take
way too long to fix them all. So I just disabled the type check for elements (also in this commit).

Subject: [PATCH 1703/1725] Fix test/functional/mining_basic which broke in
 merge of bitcoin/bitcoin#24753 in 372f1a3c25.

Please review the last merge (not this commit) carefully. The bitcoin merge of bitcoin/bitcoin#24753
did not lead to any changes in the mining_basic functional test, so it's possible I made a mistake
which caused this test to be affected.

Subject: [PATCH 1705/1725] Disables functional test tool_signet_miner.py,
 since signet mining is not needed in Elements.

Ideally, this new test (added in last commit) should work in Elements, but I couldn't get
it working. Please look into if you can get this test working. Perhaps we need to set
g_con_elementsmode to False, or something similar.

Subject: [PATCH 1707/1725] fix for rpc_psbt.py

replaced the failing sendall call with walletcreatefundedpsbt

saw this in wallet_taproot.py during the merge (line 454)

obviously something is missing in sendall when the psbt is serialized it
is missing the asset for the outputs

Subject: [PATCH 1709/1725] Bug fix: when CheckChallenge(...) is called on a
 trimmed header, temporarily untrim it in order to extract the proof.

Without this fix, there would be an exception in this scenario, because a trimmed
header no longer has any proof information attached to it.

This scenario was occuring when a pre-dynafed node with trimmed blocks would receive
a new block header from its peer. The pre-dynafed node would try to validate the header
by comparing its proof to the previous block's proof, and this would cause an exception
if the previous block had pruned.

New headers are not pruned as soon as they're received. Rather, they are pruned whenever the block index
is flushed to disk. So, this behavior was only being observed in functional tests, when a pre-dynafed trimmed
node was restarted.

Subject: [PATCH 1721/1725] coinselection: fix assert error in
 getselectionwaste

fix for intermittent assertion error in getselectionwaste
introduced in f46275d011c057b915c1129bde4973d5c968d088 as part of merge
for bitcoin/bitcoin#25647

the assertion would trigger in a fundrawtransaction call in
feature_confidential_transactions.py where the transaction inputs
included a non-policy asset.

during the loop in getselectionwaste, if the non-policy input waste was
calculated first the assertion would be triggered because
selected_effective_value has not yet met the selection target, because
non-policy coins have 0 effective value

the fix changed the assertion to an if statement, only adding to the
waste metric when selected_effective_value meets the target.
