RabbitMQ 3.5.2

Release Highlights

Server

Enhancements

• Improve integration with Docker (#113). Problems which were previously worked around in the official Docker image, were fixed in RabbitMQ. In particular:
  • Add a way to send log messages (both "normal" and sasl messages) to stdout (#128).
  • Do not try to use exec before su ... as su(1) forks a process anyway (since 3.5.0, #129).
• Report a queue is under flow control only if it was in this situation in the last 1 second, instead of the last 5 seconds previously (#138).
• Add a check to ensure the Mnesia directory is not shared with the PID file location or the plugin expansion directory (#120). This should help users facing non-working automatic clustering.

Bug fixes

• Ensure the file handle cache remains under the memory high watermark when syncing a mirrored queue (since 2.0.0, #134).
• Restore support for messages stored on disk with the previous x-death header format (since 3.5.1, #152).
• Ensure passwords containing $ characters are properly escaped so they are not interpreted by the shell, when a password is changed using rabbitmqctl change_password (since 1.5.2, #66).

Plugin: Management UI

Enhancements

• Allow to configure rates_mode even if only rabbitmq-management-agent is enabled (rabbitmq/rabbitmq-management#33). Thanks to @databus23 for the idea and tests!

Bug fixes

• Fix a badarith crash if for some reasons, the disk free space or the file descriptors count are temporarily reported incorrectly (rabbitmq/rabbitmq-management#30).

Plugin: STOMP

Bug fixes

• Ensure the "processor" thread is terminated at the same time the "reader" thread exits (rabbitmq/rabbitmq-stomp#7). Thanks to @martink2 for the report and tests!

Client library: Java

Bug fixes

• Use a timeout to ensure a closing channel does not wait for the server forever (since 1.5.0, rabbitmq/rabbitmq-java-client#46). Thanks to @dpratt for the patch!
• Interrupt the thread when an InterruptedExceptions is caught instead of ignoring it (rabbitmq/rabbitmq-java-client#52). Thanks to @vfelberg for the report!
• Ensure the virtual host is correct in the generated URI in AMQConnection.toString() (since 1.4.0, rabbitmq/rabbitmq-java-client#42). Thanks to @dharrigan for the patch!

Documentation

• Fix documentation of Recoverable.addRecoveryListener() (rabbitmq/rabbitmq-java-client#40). Thanks to @xuwei-k for the patch!
• Fix several typos (rabbitmq/rabbitmq-java-client#39). Thanks to @xuwei-k for the patch!

Client library: .NET

Bug fixes

• Rework heartbeat handling to fix several timeout issues (rabbitmq/rabbitmq-dotnet-client#68). Thanks to @btecu for the report and tests!
• Ensure timers are destroyed when a connection is closed (since 3.5.0, rabbitmq/rabbitmq-dotnet-client#58). Thanks to @chrhlnd for the report and tests, and @mikebridge and @acquleo for the tests!
• When a channel is closed, ensure consumer dispatch for other channels are not affected (since 3.5.0, rabbitmq/rabbitmq-dotnet-client#63). Thanks to @ferviri for the patch!
• Fix a NullPointerException in MapMessageBuilder.GetContentBody() (since 3.5.0, rabbitmq/rabbitmq-dotnet-client#53). Thanks to @BrentSouza for the report!

Client library: Erlang

Enhancements

• Treat a server shutdown as an expected event and do not report an error (rabbitmq/rabbitmq-erlang-client#11). Thanks to @gotthardp for the patch!

Building and packaging

Enhancements

• Upgrade Mac OS X standalone package to Erlang/OTP 17.5 (#97).

Bug fixes

• Fix a problem where Erlang crash dumps (erl_crash.dump) were created when using the Mac OS X standalone package, even though RabbitMQ was running properly (#96). Thanks to Vitaly Numenta for the report!
• Ensure rabbit_misc:otp_release/0 returns an appropriate value when using the Mac OS X standalone package (#106).
• Ignore $RABBITMQ_PID_FILE set in /etc/rabbitmq/rabbitmq-env.conf as it would break the init script (#127).
• Ensure $RABBITMQ_PID_FILE is not used before being set in the Debian init script (since 2.8.2, #126).
• Use $(MAKE) instead of hard-coding make in the MQTT (rabbitmq/rabbitmq-mqtt#23) and STOMP (rabbitmq/rabbitmq-stomp#9) plugins.
