Release Notes

dbus2/zbus (zbus)

v5.0.0: 🔖 zbus 5.0.0

Compare Source

• 👽️ Adapt to zvariant 5.0 API. This brings in massive performance improvements to message
  encoding and decoding.
• 💥 Breakinging changes:
  • Message body signature now mandatory.
  • proxy macro respects visibility. This includes all types generated by proxy. Unfortunately
    this means that the existing code will have to set the visiblity explicitly to pub if they
    were relying on the generated proxy to be public.
  • Drop support for DBUS_COOKIE_SHA1 auth mechanism. #​727
    • It drags the sha1 crate as a dependency, which can be problematic for some users. #​543
    • It makes the handshake more complex, not allowing to pipeline all the commands.
    • It's not widely used. If EXTERNAL is not an option, you might as well just use ANONYMOUS.
  • 🛂 Only support one authentication method at a time. Now that we're down to only two
    authentication mechanisms with one of them being no-authentication, this really makes sense
    since we can just autodetect what authentication method to use for a specific socket type on a
    specific platform. This also simplifies the handshake logic and will allow us to pipeline the
    whole client-side handshake in the future, when we can drop the xdg-dbus-proxy workarounds. #​781
  • Drop unnecessary lifetimes on genarated signal streams.
  • Streamline Message & message::Builder constructors. They should be named the same and take the
    same type of arguments.
  • proxy::Defaults now has typed values.
  • Rename proxy::ProxyDefault to proxy::Defaults.
  • 🔥 Drop API deprecated in 4.0.
  • Minor changes in fdo API.
• ✨ New features:
  • interface now generates a trait, Signals, that provides the same signal
    methods as user specifies but w/o the SignalEmitter argument (#​871). The macro also generates
    2 implementations of this trait for:
    • InterfaceRef, for emitting signals from outside the context of an interface
      method.
    • SignalEmitter, for emitting signals from inside an interface methods.
  • Add SignalContext::emit. Add a new method to SignalContext that allows emitting a signal for
    a given interface and singal name.
  • Add Connection::graceful_shutdown.
  • Add conn::AuthMechanism::as_str(). This gives you a static string representation of the
    mechanism. We'll use this in a following commit to avoid an allocation.
  • Add Socket::auth_mechanism. The socket impl will now inform us which authentication mechanism
    should be used with it. The implementation can choose this based on the socket type and the
    target platform.
  • Allow specifying visibility of interface-generated proxy. This implies that by default, it will
    be private.
  • ObjectServer now implements Clone.
• 🚚 Renames and moves:
  • Rename SignalContext to SignalEmitter. Since now this emits signals, this is a more
    appropriate name. We keep a deprecated SignalContext type alias as well as the
    signal_context attribute of interface for not completely breaking the existing code.
  • Move AuthMechanism from crate root to conn. We leave the AuthMechanism in the root as
    deprecated.
• 🚑️ Gracefully handle serial number wrap. When SERIAL_NUM wraps past u32::MAX back to zero,
  the conversion to NonZeroU32 panics. #​946
• 🩹 Fix some lifetimes in Proxy API. We were unnecessarily constraining the lifetimes in some of
  the Proxy API.
• ⚡️ Optimizations
  • Only enable Guid::generate() if p2p feature is enabled.
  • Use relaxed load order for serial number fetch & add.
  • msg::Header no longer allocates.
  • Avoid deserialization of msg::Header needlessly.
• 🚩 Add serde_bytes Cargo feature. This is just a proxy feature for zvariant's serde_bytes
  feature. #​1052
• 🚩 Feature-gate blocking API. Add a cargo feature called blocking-api to zbus &
  zbus_macros. When enabled, the zbus::blocking module is available. When disabled, proxy
  macro ignores the value of gen_blocking attribute and doesn't generate blocking proxy. This
  feature is enabled by default.
• ➕ Add camino feature as proxy for zvariant feature of the same name.
• ➖ Dependendies removed:
  • Remove dependency on sha1 crate.
  • Drop direct dep on futures-sink.
  • rand now an optional dependency. It is only enabled if p2p feature is enabled. This means
    that rand dependency is dropped for typical users.
• ⬆️ Updated dependencies:
  • zvariant to 5.0.
  • windows-sys to 0.59.
  • tokio-vsock 5. #​643
• ⬆️ Bump MSRV to 1.81.
• 📝 Documentation
  • Tidy documentation across entire crate.
  • Improve blocking module docs.
  • Correct wrong documentation links.
  • Remove a now incorrect warning from Message::header method.
• ✏️ Fix doc list item missing indentation.
• 🚨 Drop invalid cfg from documentation example.

I'm inclined to wait till 1.83, since zbus does not support 1.81 any longer

Now that rust 1.83 has been released, is it time to do this upgrade?
