rabbitmq_v3_5_3

f04d53f

RabbitMQ 3.5.3

Release Highlights

Server

Enhancements

If rabbitmqctl can't contact a node, suggest to verify any Erlang TLS distribution configuration (#162).

Bug fixes

Ensure the memory monitor is fully started before the file handle cache is used (since 3.5.2, #157). Before, the problem could lead to the following crash during RabbitMQ startup:

=CRASH REPORT==== ... ===
crasher:
  initial call: gen:init_it/6
  pid: <0.229.0>
  registered_name: []
  exception exit: {noproc,
                      {gen_server,call,
                          [vm_memory_monitor,get_memory_limit,infinity]}}
    in function  gen_server2:terminate/3 
...

Thanks to Carl Hörberg and Gilles Danycan for the bug report!

Plugin: Management UI

Bug fixes

Fix a crash during RabbitMQ startup if force_fine_statistics is set in rabbitmq_management_agent configuration (since 3.5.2, rabbitmq/rabbitmq-management-agent#4). The error was:
```
BOOT FAILED
===========

Error description:
{could_not_start,rabbit,
   {{case_clause,false},
    [{rabbit_mgmt_db_handler,ensure_statistics_enabled,0,[]},
...
```
Thanks to Kevin Blackwell for the bug report!

Documentation

When the management UI warns about network partitions, add a link to the documentation which gives explanations and possible solutions (rabbitmq/rabbitmq-management#43).

Client library: Java

Bug fixes

During handshake, await on continuations with a timeout (rabbitmq/rabbitmq-java-client#65). Unfortunately, this change breaks the API. Thanks to @jhalterman for the bug report and testing!

Feature deprecation

Deprecate com.rabbitmq.client.Channel methods related to the old flow control (rabbitmq/rabbitmq-java-client#59):

boolean flowBlocked();
void addFlowListener(FlowListener listener);
boolean removeFlowListener(FlowListener listener);
void clearFlowListeners();

Documentation

Revisit com.rabbitmq.client.Channel documentation (rabbitmq/rabbitmq-java-client#60, rabbitmq/rabbitmq-java-client#30, rabbitmq/rabbitmq-java-client#32).
Improve documentation around recovery listeners (rabbitmq/rabbitmq-java-client#35).

Building and packaging

Bug fixes

When updating Git remote URLs, use git set-url ... to set the fetch URL, not git set-url --fetch ... (since 3.5.1).

Upgrading

To upgrade a non-clustered RabbitMQ simply install the new version. All configuration and persistent message data are retained.

To upgrade a RabbitMQ cluster, follow the instructions at:

rabbitmq_v3_5_2

b5cc6a0

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.

rabbitmq_v3_5_1

4fdd61b

RabbitMQ 3.5.1

Release Highlights

Server

Enhancements

Introduce a new channel log category for channel log messages (#74).

Bug fixes

Ensure consumer_closed events are emitted for the actually closed channels only, not all of them (since 3.3.0, #86). The events were filtered later in the management plugin so the behaviour was correct. However, the broker did way too much work.
Ensure the number of x-death message headers doesn't grow indefinitely (#78). Now, there is a single entry for each {queue, reason} pair.
Adjust the file read buffer cache size to avoid useless reads (since 3.5.0, #69). Before this fix, reading a file backward would cause the buffer to be filled and thrown away quickly, leading to a large I/O bandwidth consumption.
Ensure the priority queue plugin reports its memory consumption properly (since 3.5.0, #67). Before this fix, the queue might not be paged out under memory pressure.
Prevent a crash while synchronising paged out priority queues (since 3.5.0, #65). This was caused by priority queues accessing message properties without checking their existence.
Pass the PID file to rabbitmqctl stop in rabbitmq-server.ocf, exactly like Debian- and Red Hat-flavour init scripts (since 2.6.0, #72).

Plugin: AMQP 1.0

Bug fixes

Fix heartbeats (rabbitmq/rabbitmq-amqp1.0#6).
Respond with a protocol error if a disposition frame is incorrect (rabbitmq/rabbitmq-amqp1.0#8).
Fix a crash if the initial-delivery-count is not 0 (rabbitmq/rabbitmq-amqp1.0#9).

Client library: Java

Enhancements

Uplift RecoveryAwareAMQConnection and RecoveryAwareChannelManager to use ConnectionFactory's custom threadFactory (rabbitmq/rabbitmq-java-client#33).

Client library: .NET

Enhancements

Make IQueueingBasicConsumer and ISubscription public (rabbitmq/rabbitmq-dotnet-client#47).
Add a test case to ensure consumers are properly resumed after automatic recovery (rabbitmq/rabbitmq-dotnet-client#50).

Bug fixes

Ensure no bindings are lost during automatic recovery (since 3.4.0, rabbitmq/rabbitmq-dotnet-client#43).
Ensure client certificates are not mandatory with SSL connections (rabbitmq/rabbitmq-dotnet-client#46). There was a previous attempt in fixing this but it broke the ability to require specific SSL versions (since 3.5.0, rabbitmq/rabbitmq-dotnet-client#44).
Ensure ConsumerWorkService uses the scheduler it is constructed with (since 3.5.0, rabbitmq/rabbitmq-dotnet-client#40).

Building and packaging

Enhancements

Teach make checkout to retry if GitHub closes the connection (rabbitmq/rabbitmq-public-umbrella#17).
Add make sync_gitremote and make sync_gituser targets to synchronize Git remote and user/email accross the umbrella and all its subrepositories (rabbitmq/rabbitmq-public-umbrella#5).

Bug fixes

Make internal database files private to the group (eg. rabbitmq) (#68).
Improve make up_c to work with detached HEAD. This allows to checkout a tag again (since 3.5.0, rabbitmq/rabbitmq-public-umbrella#6).
Fix make status so it walks through directories correctly (rabbitmq/rabbitmq-public-umbrella#13).
Use $(MAKE) instead of a hard-coded make in make plugins-srcdist (rabbitmq/rabbitmq-public-umbrella#18).
