RabbitMQ 3.7.5

RabbitMQ 3.7.5

RabbitMQ 3.7.5 a maintenance release that primarily includes bug fixes.

Upgrades and Compatibility

This release includes one potential incompatibility with earlier 3.7.x releases. It will only affect applications that use a lot (at least hundreds) of channels per connection. Previous behavior can be restored via configuration.

See 3.7.0 release notes upgrade and compatibility notes if upgrading from an earlier release.

See the Upgrading guide for general documentation on upgrades.

See RabbitMQ change log for release notes of other releases.

Changes

Core Server

Bug Fixes

• Topic authorization check could fail with an exception.

  GitHub issue: rabbitmq-server#1538

• Some runtime parameters and operator policies were rejected during definition import.

  GitHub issue: rabbitmq-management#565, rabbitmq-federation#73

• Queues could run into an exception under memory pressure.

  GitHub issue: rabbitmq-server#1582

• During parallel cluster formation nodes could run into an exception when inserting seed data
  (default virtual host, user and permissions).

  GitHub issue: rabbitmq-server#1556

Enhancements

• New ha-promote-on-failure queue mirroring setting to augment already existing ha-promote-on-shutdown.

  GitHub issue: rabbitmq-server#1578

• queue.delete operations will now force delete queues that don't have a promotable
  master.

  GitHub issue: rabbitmq-server#1501

• Lock contention in internal database is now much lower when a node with a lot of exclusive queues
  shuts down or is otherwise considered to be unavailable by peers. This means fewer CPU cycles
  spent cleaning up the exclusive queues.

  GitHub issue: rabbitmq-server#1570

• Default max number of channels allowed on a connection (a.k.a. channel_max) has been lowered from 65535 to 2047.
  The new default is much safer and will reduce the effect application channel leaks have on node resource consumption. This is a potentially breaking change.

  Systems where a lot (at least hundreds) of channels per connection are used should explicitly override channel_max in the config file to a higher suitable value, e.g.:

  channel_max = 4000
  

  GitHub issue: rabbitmq-server#1593

• Ranch dependency has been updated to 1.5.x which should prevent rare cases of mass termination of client connections.

CLI Tools

Bug Fixes

• -t (--timeout) is now only displayed for commands that will actually use it.

  GitHub issue: rabbitmq-cli#236

Management Plugin

Bug Fixes

• GET /api/overview could fail if SNI for management plugin listener was configured.

  GitHub issue: rabbitmq-management#567

• rabbitmqadmin could run into an exception with certain formatting settings on Python 2.x.

  GitHub issue: rabbitmq-management#568

• HTTP API stats documentation used incorrect field names.

  GitHub issue: rabbitmq-management#561

LDAP Plugin

Bug Fixes

• LDAP server-initiated connection closure was not handled gracefully by connection pool.
  Kudos to Adam Gardner for doing all the hard work investigating this issue.

  GitHub issues: rabbitmq-auth-backend-ldap#82, rabbitmq-auth-backend-ldap#90

• auth_ldap.timeout now defaults to 300 seconds instead of infinity.

  GitHub issue: rabbitmq-auth-backend-ldap#81

• group_lookup_base was not configurable via the new style config format.

  GitHub issue: rabbitmq-auth-backend-ldap#85

• auth_ldap.log didn't accept network_unsafe for severity value.

  GitHub issue: rabbitmq-auth-backend-ldap#86

Enhancements

• It is now possible to configure TLS options for LDAP server connections via the new style config format.

  GitHub issue: rabbitmq-auth-backend-ldap#88

Federation Plugin

Bug Fixes

• Federation upstream sets could run into a type error with exchange federation.

  GitHub issue: rabbitmq-federation#75

Shovel Plugin

Bug Fixes

• Valid dynamic Shovel properties can be rejected by validation.

  GitHub issue: rabbitmq-shovel#38

• Shovel names are again included into (application-provided) connection names and can therefore
  be seen in the management UI.

  GitHub issue: rabbitmq-shovel#40

Peer Discovery AWS Plugin

Bug Fixes

• China-based AWS regions now use a correct base API URI.

  GitHub issue: rabbitmq-peer-discovery-aws#23

• The plugin could fail to discover all nodes in a returned instance set.

  GitHub issue: rabbitmq-peer-discovery-aws#20

Peer Discovery Kubernetes Plugin

Enhnacements

• The plugin now supports randomized startup delay with much lower default values
  since RSD is not really necessary for stateful set deployments.

  GitHub issue: rabbitmq-peer-discovery-k8s#23

AMQP 1.0 Client

Bug Fixes

• It wasn't possible to send some messages using QPid JMS client over AMQP 1.0.

  GitHub issue: rabbitmq-amqp1.0#61

Web MQTT Plugin

Bug Fixes

• New style config format was not interpreting IP addresses correctly.

  GitHub issue: rabbitmq-web-mqtt#26

Web STOMP Plugin

Bug Fixes

• It wasn't possible to configure TCP listener(s) in the new style config format.

See 3.7.0 release notes upgrade and compatibility notes if upgrading from an earlier release.

See the Upgrading guide for general documentation on upgrades.

Changes

Core Server

Bug Fixes

• Logging to amq.rabbitmq.log exchange is available again as a logging mechanism. Note that
  the user must opt-in by setting log.exchange = true in the config file.

  GitHub issue: rabbitmq-server#1456

• During node boot, the logger will temporarily accept a much higher maximum rate so that no messages are dropped.

  GitHub issue: rabbitmq-server#1471

• Plugin activation could hang if a plugin's channel interceptor failed to activate with an exception.

  GitHub issue: rabbitmq-server#1477

• During node boot, virtual host that are not yet initialised could be queried for status, which
  resulted in log noise.

  GitHub issue: rabbitmq-server#1472

Enhancements

• Internal authN backend will now prohibit logins with blank passwords. Such attempts
  are usually made by mistake because a passwordless user that was meant to authenticate
  using x509 (TLS) certificates was not configured to use the correct authentication
  mechanism.

  Note that the same behavior can already be achieved using a credential validator, so this is
  just an extra safety measure.

  GitHub issue: rabbitmq-server#1465

Management Plugin

Bug Fixes

• Definition import now stores global parameters in a way that the MQTT plugin expects.

  GitHub issue: rabbitmq-management#528

• User update form now successfully updates tags for passwordless users (or if the password is cleared at the same time).

  GitHub issue: rabbitmq-management#533

Enhancements

• Requeue is now the default option in the Get Messages section.

  Contributed by @dparkinson.

  GitHub issue: rabbitmq-management#542

• For passwordless users, the "no password" option on the user editing form is now preselected.

  GitHub issue: rabbitmq-management#537

LDAP AuthN/AuthZ Backend Plugin

Bug Fixes

• More config keys are now supported via new style config format.

  GitHub issue: rabbitmq-auth-backend-ldap#78

Peer Discovery Consul Plugin

• When a node registers with Consul it will now set its initial health check status to passing.
  Previously the node would be in the critical state until it first reported its health for the
  first time (in 15 seconds with default settings), which could prevent its peers from discovering it.

  Kudos to @andersenleo for investigating this issue and recommending a solution.
