- Improved Moped Failover (John Hyman)
- Relaxing BSON dependency to allow for 3.1.0 upgrade.
-
#351 Fixing retries with authentication. (Wandenberg Peixoto)
-
Bump BSON dependency to 3.0.4
- #345 Writes fail with ConnectionPool::PoolShuttingDownError. (fedenusy, dblock)
- #333, #336 Disconnect even when IP address not resolved and fix shutdown pool for node. (durran)
- Dont include peers if node already in the list There was a big memory leak, that was including all nodes in the list in every refresh cycle. (Arthur Neves)
-
#288, #278, #252, #247, #275, #290 Re-apply credentials when connection is lost with the server. (zarqman)
-
mongoid/mongoid#3790 Allow Session pool_timeout option. (Niels Ganser)
-
#297 Better retry on authentication. (Jonathan Hyman)
-
Moped 2 now only supports MongoDB 2.4.0 and higher.
-
Query.cursor will return a Enumerable instead of a Enumerator. (Arthur Neves)
-
Moped's BSON implementation has been removed in favor of the 10gen bson gem 2.0 and higher. All
Moped::BSONreferences should be changed to justBSON. -
#190 Connection retries are now logged. (Jan Paul Posma)
-
#133 Moped now supports the new read preferences that the core drivers provide. These include:
:primary: Will always read from a primary node. (default):primary_preferred: Attempt a primary first, then secondary if none available.:secondary: Will always read from a secondary node.:secondary_preferred: Attempt a secondary first, then primary if none available.:nearest: Attempt to read from the node with the lowest latency.
Sample syntax:
Moped::Session.new([ "127.0.0.1:27017" ], read: :secondary) session.with(read: :nearest)[:users].findThe
:consistencyoption is no longer valid and will be ignored. -
#92 Moped now defaults all writes to propagate (formerly "safe mode") and now has different propagate semantics:
{ w: -1 }: Don't verify writes and raise no network errors.{ w: 0 }: Don't verify writes and raise network errors.{ w: 1 }: Verify writes on the primary node. (default){ w: n }: Verify writes on n number of nodes.{ w: :majority }: Verify writes on a majority of nodes.
Sample syntax:
Moped::Session.new([ "127.0.0.1:27017" ], write: { w: 0 }) session.with(write: { w: -1 })[:users].insert(document)The
:safeoption is no longer valid and will be ignored.
- #196 Adding method on collection to rename itself (Arthur Neves)
- #210 Moped no longer attempts to refresh arbiters as they cannot be queried.
- #208 Fixed local jump errors in node. (Brian Norton)
-
The session now has an additional configuration option, called
auto_discover. which defaults totrue. Auto-discovery means that nodes that are not provided explicitly to the session but are visible will become available for read/write in the application. This behavior is the same as the existing behavior.The change here is to be able to turn this off by setting
auto_discover: false. This will tell Moped to only send messages to nodes explicitly provided when instantiating the session.Example:
Moped::Session.new([ "127.0.0.1:27017" ], auto_discover: false)
- #191 Checking for "not authorized" in error messages. (Jonathan Hyman)
-
#174 Check for "unauthorized" in error messages since codes are not always there. (Jon Hyman)

session[:bands].find(name: "Blur").max_scan(50) -
#143 Aggregation pipeline commands no longer force to read from primary.
-
#141 Timeouts on sockets are now set to the timeout level provided, as well is active checks now happen before sending both reads and writes.
-
#140 Nodes that were provided to Moped's session in intialization, that were removed from the replica set but still alive and accepting connections will no longer be in the list of available nodes.
-
#138 Aggregation pipeline now supports array or splat args. (Gosha Arinich)
-
#41
Moped::BSON::ObjectId.from_timenow accepts auniqueoption to ensure the generated id is unique.Moped::BSON::ObjectId.from_time(time, unique: true) -

-
#137
IOErrorexceptions during connection go through reconnect process properly. (Peter Kieltyka) -

Database#collection_names.
-
#131 Give better error messages when assertion and assertionCode are present in the result.
-
#130 Flag down as down in refresh when not primary or secondary. (Nilson Santos Figueiredo Jr)
-
#128 Fix refresh check to only check nodes that have been down longer than the refresh boundary using the proper interval.
-
#125 Batch size and no timeout are now respected by queries. (Derek Buttineau)
-
#124 Fix packing of bytes in core messages for big endian systems.
-

-
#114 Moped now accepts connecting with a URI. (Christopher Winslett)
Moped::Session.connect("mongodb://localhost:27017/my_db") -
#79 Tailable cursors are now supported. These are just Ruby
Enumeratorsthat keep the cursor open until the next document appears. The cursor will be closed when it becomes "dead".enumerator = session[:users].find.tailable.each enumerator.next # Will stay open until next doc. -
mongoid/mongoid#2460 Moped now makes the connection timeout configurable by passing a
:timeoutoption to the session. This defaults to 5 seconds.Moped::Session.new([ "node1:27017", "node2:27017" ], timeout: 5) -
#49 Support for the 2.2 aggregation framework is included. (Rodrigo Saito)
session[:users].aggregate({ "$group" => { "_id" => "$city", "totalpop" => { "$sum" => "$pop" } } }) -
#42 Moped now supports SSL connections to MongoDB. Provide the
ssl: trueoption when creating a newSession. This is currently experimental.Moped::Session.new([ "ssl.mongohq.com:10004" ], ssl: true)
-
#110 Handle timeout errors with SSL connections gracefully and mark nodes as down without failing any other queries.
-
#109 Moped reauthorizes on "db assertion failures" with commands that have an unauthorized assertion code in the reply.
- Moped now ensures that when reading bytes from the socket that it continues
to read until the requested number of bytes have been received. In the case
of getting
nilback it will raise aConnectionFailureand go through the normal failover motions.
-
#108 Connection drops that would result in a
nilresponse on socket read or aSocketErrornow re-raise aConnectionFailureerror which causes the replica set to go through it's failover behavor with node refreshing. -
#104
Query#explainnow respects limit. -
#103 Port defaults to 27017 instead of zero if not provided. (Chris Winslett)
-

-
#90 Include arbiters in the list of nodes to disconnect. (Matt Parlane)
-
#87
Moped::BSON::ObjectId.legal?now returns true for object ids. -
#85 Allow
===comparisons with object ids to check for equality of the underlying string. (Bob Aman) -
#84 Query hints are no longer wiped on explain.
-
#60/#80 Moped now gracefully handles replica set reconfig and crashes of the primary and secondary. By default, the node list will be refreshed every second and the operation will be retried up to 30 times. This is configurable by setting the
:max_retriesand:retry_intervaloptions on the session.Moped::Session.new( [ "node1:27017", "node2:27017" ], retry_interval: 0.5, max_retries: 45 )
- mongoid/mongoid#2430 Don't include $orderby criteria in update calls.
-

-
#75 Ensure that
Errno::EHOSTUNREACHis also handled with other socket errors.
-
#73 Raise a
Moped::Errors::CursorNotFoundon long running queries where the cursor was killed by the server. (Marius Podwyszynski) -
#72 Reauthenticate properly when an
rs.stepDown()occurs in the middle of cursor execution. -
#71 When DNS cannot resolve on node initialization, the node will be flagged as down instead of raising a
SocketError. On subsequent refreshes Moped will attempt to resolve the DNS again to determine if the node can be brought up.
-
#63
Database#collection_namesnow returns collections with "system" in the name that aren't core MongoDB system collections. (Hans Hasselberg) -
#62 Ensure
Connection#alive?returns false if I/O errors occur. (lowang) -

-
mongoid/mongoid#2251 Allow
continue_on_erroroption to be provided to inserts. -
mongoid/mongoid#2210 Added
Session#disconnectwhich will disconnect all nodes in the cluster from their respective database servers. Useful for cases where a large number of database connections are being created on separate threads and need to be explicitly closed after their work is completed. -
#33 Added
Session#databasesandSession#database_namesas a convenience for getting all database information for the server.session = Moped::Session.new([ "localhost:27017" ]) session.database_names #=> [ "moped_test" ] session.databases #=> { "databases" => [{ "name" => "moped_test" }]}
-
#45 When providing database names with invalid characters in them, Moped will now raise an
InvalidDatabaseNameerror. -
#41
ObjectId.from_timenow only includes the timestamp, no machine or process information.
-
#44 Fixed order of parameters for loading timestamps. (Ralf Kistner)
-
#40 Fix explain to return correct number of scanned documents and time.
- Queries now can be duped/cloned and be initialized properly.
- #37 Use
TCP_NODELAYfor socket options. (Nicolas Viennot)
