Release History

0.18.0 (Unreleased)

Features Added

  • Added ConnectionError type that's returned when a connection is no longer functional.
  • Added LinkTargetCapabilities() option to specify desired target capabilities.
  • Added SASLType used when configuring the SASL authentication mechanism.
  • Added Ptr() method to SenderSettleMode and ReceiverSettleMode types.

Breaking Changes

  • Removed ErrConnClosed and ErrTimeout sentinel error types.
  • The following methods now require a context.Context as their first parameter.
    • Client.NewSession(), Session.NewReceiver(), Session.NewSender()
  • Removed context.Context parameter and error return from method Receiver.Prefetched().
  • The following type names had the prefix AMQP removed to prevent stuttering.
    • AMQPAddress, AMQPMessageID, AMQPSymbol, AMQPSequenceNumber, AMQPBinary
  • Various Default* constants are no longer exported.
  • The args to Receiver.ModifyMessage() have changed.
  • The "variadic config" pattern for Client, Session, Sender, and Receiver constructors has been replaced with a struct-based config.
    • This removes the ConnOption, SessionOption, and LinkOption types and all of the associated configuration funcs.
    • The sender and receiver specific link options have been moved into their respective options types.
    • The ConnTLS() option was removed as part of this change.
  • The Dial() and New() constructors now require an *ConnOptions parameter.
  • Client.NewSession() now requires a *SessionOptions parameter.
  • Session.NewSender() now requires target address and *SenderOptions parameters.
  • Session.NewReceiver() now requires source address and *ReceiverOptions parameters.
  • The various SASL configuration funcs have been slightly renamed.

Bugs Fixed

  • Fixed potential panic in muxHandleFrame() when checking for manual creditor.
  • Fixed potential panic in attachLink() when copying source filters.
  • New() will no longer return a broken *Client in some instances.
  • Incoming transfer frames received during initial link detach are no longer discarded.
  • Session will no longer flood peer with flow frames when half its incoming window is consumed.
  • Newly created Session won't leak if the context passed to Client.NewSession() expires before exit.
  • Newly created link won't leak if the context passed to link.attach() expires before exit.
  • Fixed an issue causing dispositions to hang indefinitely with batching enabled when the receiver link is disconnected.

Other Changes

  • Errors when reading/writing to the underlying net.Conn are now wrapped in a ConnectionError type.
  • Disambiguate error message for distinct cases where a session wasn't found for the specified remote channel.
  • Removed link.Paused as it didn't add much value and was broken in some cases.
  • Only send one flow frame when a drain has been requested.
  • Session window size increased to 5000.
  • Creation and deletion of Session instances have been made deterministic.
  • Allocation and deallocation of link handles has been made deterministic.
