Release Notes

z-galaxy/zbus (zbus)

v6.3.0

Compare Source

✨ Added

• Hand a connection over with MessageStream::hand_over, with the new handover feature, on Linux.
• Take a connection over with Builder::take_over.
• Save and restore a Handover through zoter's traits.
• Add Connection::prepare_hand_over, for sends that don't wait.
• Add ReadHalf::can_take_unread and ReadHalf::take_unread.
• Add WriteHalf::can_resume_writes, for halves of your own.
• Resume cut-off sends, adding Connection::flush and unwritten_len.
• Look up the credentials of the peer of a unix socket.
• Add fallback interfaces to the object server. #​2112
• Support jiff as an alternate time crate.

♻️ Changed

• Write the sockets that zbus drives from the connection itself.
• Make Builder::build_message_stream available with the handover feature too.
• Keep a long message that Reader reads in the reader itself.

📝 Documentation

• Describe the ConnectionStats counters as the specification does.
• Document when a lazily started object server misses calls.

🐛 Fixed

• Convert a slice of Fds into an Array. #​1730
• Escape the bytes of a displayed byte string. #​1813
• Use the specified names of the ConnectionStats FD entries. #​2126
• Close a connection before its streams end.
• End a connection over a unix socket or a channel on UnexpectedEof.
• Fail MessageStream::for_match_rule if the reader ends meanwhile.
• Fail a method call before it is sent once the reader ended.
• Make the default receive_message cancel-safe and count its fds.
• Leave the process descriptor out where the kernel has none.
• Look up all of the groups of a user, however many.
• Give each group of the peer of a unix socket once.
• Take the credentials of a peer in another PID namespace.
• Send a message with fds in a write of its own.

⚡️ Performance

• Keep the credentials that the server handshake looked up.
• Take the groups of a peer from its socket on Linux.

✅ Testing

• Speed up the tests of big sends through a half of your own.
• Subscribe before registering the fallback in a fallback test.
• Keep ReadinessFirst's readiness waits across polls.

v6.2.1

Compare Source

🐛 Fixed

• Check message bodies without an if let guard.

✅ Testing

• Benchmark taking a burst of signals off a connection's socket.
• Benchmark checking a body of dicts of variants.

v6.2.0

Compare Source

✨ Added

• Add Connection::send_all. #​2078
• Add WriteHalf::send_messages.

♻️ Changed

• Hand several buffers to each send of a runtime's socket.

🐛 Fixed

• Limit nesting for each signature, and count dict entries. #​2087
• Reject a received message whose path field isn't an object path.
• Accept references to unsized types as interface args again. #​2076

⚙️ Other

• 🦺 Reject a header with an unended string or a repeated field.
• 🦺 Let a connection check the body of each message it receives.
• 🦺 Add Body::validate, for a bus to check bodies with.
• 🦺 Check a received message as a whole, not only its fields.

⚡️ Performance

• Call the read half itself rather than through its Box.
• Read ahead of each message on the sockets that zbus drives. #​2085
• Allocate a received message once, at its exact length.
• Leave the maybe type of GVariant to the signature parser.
• Add Message::with_sender, for a bus to set senders with.
• Leave room for None in where a header field lies.
• Parse message headers with winnow rather than serde. #​2080
• Read the header fields of a message without checking them again.

✅ Testing

• Hold deserializing to the nesting that Body::validate allows.
• Benchmark parsing and checking short signatures.
• Fuzz the parser of message headers against serde.
• Benchmark decoding a received message.

v6.1.0

Compare Source

✨ Added

• Support the eavesdrop key of match rules.

💥 Breaking

• Go back to a HashMap for the interfaces of fdo::ManagedObjects, which 6.0.0 turned into a
  BTreeMap, to match the InterfacesAdded signal and PropertiesProxy::get_all. #​2064

🐛 Fixed

• Escape apostrophes in match rule strings.
• Parse match rule strings as the specification has them.
• Reply InvalidArgs to arguments that don't deserialize.

⚡️ Performance

• Don't copy the string of an OwnedMatchRule to deserialize it.
