Changes

Core Server

Enhancements

• amqqueue module and the feature flag subsystem were backported from 3.8. This makes it possible
  for plugin developers to target both 3.7.x and 3.8.x release series.

  Note that this only backports the API. There are no feature flags to enable in 3.7.17.
  No 3.8-specific features that must be enabled via feature flags were backported and there are no
  plans to do it in later 3.7.x releases.

  GitHub issue: rabbitmq/rabbitmq-server#2028

CLI Tools

Bug Fixes

• rabbitmqctl stop description had a typo.

  Contributed by Eugene Pirogov.

  GitHub issue: rabbitmq/rabbitmq-cli#363

Management Plugin

Bug Fixes

• Blank effective policy definitions were formatted as a JSON array instead of an empty object in API responses.

Changes

Core Server

Bug Fixes

• When a node hosting an exclusive queue was restarted with queue master locator being something other than "node local", redeclaration of the queue failed.

  Contributed by Lajos Gerecs.

  GitHub issue: rabbitmq/rabbitmq-server#2039

Enhancements

• It is now possible to configure default worker pool size:

  default_worker_pool_size = 1024

  This may be necessary in environments with a large number of queues (say, hundreds of thousands)
  to speed up queue and binding recovery on node boot. By default the size of the pool is
  computed as the number of available runtime schedulers.

  GitHub issue: rabbitmq/rabbitmq-server#2030

CLI Tools

Bug Fixes

• rabbitmqctl report and rabbitmqctl list_queues could fail with a {bad_argument,type} because of a 3.8-specific column was erroneously listed as supported.

  Contributed by Lajos Gerecs.

  GitHub issue: rabbitmq/rabbitmq-cli#354

Enhancements

• New health check: rabbitmq-diagnostics check_virtual_hosts.

  rabbitmq/rabbitmq-cli#302

• New observability command, rabbitmq-diagnostics log_location [--all], displays log file location(s)
  on target node. The node is assumed to be running.

  GitHub issue: rabbitmq/rabbitmq-cli#325

• New observability commands, rabbitmq-diagnostics log_tail and rabbitmq-diagnostics log_tail_stream,
  provide a way to remotely inspect recent log file entries on a running node. The commands are meant
  to be used for troubleshooting and not to automate log aggregation.

  GitHub issue: rabbitmq/rabbitmq-cli#326

• rabbitmq-diagnostics schema_info displays information about internal database schema
  (tables, their properties and metadata).

  rabbitmq/rabbitmq-cli#330

Management Plugin

Bug Fixes

• When multiple definition files were imported on node boot, errors were not reported
  the same way they would be with a single file.

  GitHub issue: rabbitmq/rabbitmq-management#710

Enhancements

• The plugin now disables client inactivity timeout for the definition import endpoints and reports
  progress using periodic 102 Processing responses so that the connection is kept alive even if importing
  definition takes a long time.

  GitHub issue: rabbitmq/rabbitmq-management#711

Shovel Plugin

Bug Fixes

• 3.7.15 introduced a regression where Shovels would not try to reconnect after a network
  failure.

  GitHub issue: rabbitmq/rabbitmq-shovel#60

Web MQTT Plugin

Bug Fixes

• Default maximum connection limit set by a dependency (1024) has been lifted.

  GitHub issue: rabbitmq/rabbitmq-web-mqtt#55

• Client ID wasn't propagated to connection metadata for MQTT connections over WebSockets.

  GitHub issue: rabbitmq/rabbitmq-web-mqtt#57

Web STOMP Plugin

Bug Fixes

• Default maximum connection limit set by a dependency (1024) has been lifted.

  GitHub issue: rabbitmq/rabbitmq-web-stomp#113

Trust Store Plugin

Enhancements

• It is now possiible to configure HTTPS proxy settings for the HTTPS backend.

  GitHub issue: rabbitmq/rabbitmq-trust-store#69

Debian Package

Bug Fixes

• Exit code 69 is now considered a success again in the systemd service file.

Changes

Core Server

Bug Fixes

• rabbitmq.conf validation errors on startup unintentionally lacked a lot of relevant details.

  Contributed by Grigory Starinkin.

  GitHub issue: rabbitmq/rabbitmq-server#1985

• Message store compaction could enter a race condition with queue operations.

  GitHub issue: rabbitmq/rabbitmq-server#2000

• Internal schema data store consistency checks used an on-disk location which could be unintentionally
  preserved between deployments and make subsequent deployments fail. Now an entirely in-memory set of tables
  is used for schema consistency checks.

  GitHub issue: rabbitmq/rabbitmq-server#1960

• When publisher confirms had to send both positive and negative acknowledgements around the same time,
  it could be done in a way that would violate expectations of most client libraries.

  GitHub issue: rabbitmq/rabbitmq-server#1719

• Policy validation could allow invalid values in certain cases.

  GitHub issue: rabbitmq/rabbitmq-server#1999

• amq.rabbitmq.log exchage was lazily initialised and could be temporarily unavailable after node start.

  GitHub issue: rabbitmq/rabbitmq-server#1973

• Clearing a policy with overflow behaviour or removing the key from it did not
  roll back the overflow behaviour to drop-head (the default).

  GitHub issue: rabbitmq/rabbitmq-server#1980

• Missing getconf command (used to fetch platform's memory page size) is now handled more gracefully
  with a default value.

  GitHub issue: rabbitmq/rabbitmq-common#318

  and internal event backlog in case of high connection churn.

  GitHub issues: rabbitmq/rabbitmq-server#1971,
  rabbitmq/rabbitmq-server#1975

Management Plugin

Bug Fixes

• Enabled kernel sendfile for HTTP API documentation pages could lead to leaked file descriptors
  when those pages are accessed repeatedly (e.g. a tab is always open for weeks and weeks).
  The plugin now disables sendfile for those static files by default. It can be manually enabled
  via configuration as needed.

  GitHub issue: rabbitmq/rabbitmq-management#698

• Listing permissions could result in a 500 response.

  GitHub issue: rabbitmq/rabbitmq-management#688

• When CORS headers were enabled, binding endpoints were inaccessible due to an exception.

  GitHub issue: rabbitmq/rabbitmq-management#687

  for those time intervals was available.

  GitHub issue: rabbitmq/rabbitmq-management#693

• Information unit suffix incorrectly suggested that values were powers of 10 (gigabyte) instead of
  power of 2 (gibibyte).

  GitHub issue: rabbitmq/rabbitmq-management#694

AMQP 1.0 Plugin

Bug Fixes

• Default host specified in amqp1_0.default_vhost (rabbitmq_amqp1_0.default_vhost in classic config format)
  now takes precedence over default_vhost (rabbit.default_vhost) in the core broker.

  GitHub issue: rabbitmq/rabbitmq-amqp1.0#86

Shovel Plugin

Bug Fixes

• Connections to source and destination nodes are now correctly closed if topology operations
  fail on either end (e.g. due to insufficient permissions).

  Contributed by Grigory Starinkin.

  GitHub issue: rabbitmq/rabbitmq-shovel#54

• Improved handling of cases where AMQP 1.0 endpoint connection was refused access to a virtual host.

  GitHub issue: rabbitmq/rabbitmq-shovel#57

Enhancements

• The plugin now provides a new CLI command and HTTP API endpoint for restarting
  a dynamic Shovel.

  GitHub issue: rabbitmq/rabbitmq-shovel#48

Federation Plugin

Enhancements

• Queue federation now uses a more informative consumer tag value.

  GitHub issue: rabbitmq/rabbitmq-federation#66

CLI Tools

Bug Fixes

• Streamling list_* commands could hang when encountering an error from one of the cluster nodes.

  GitHub issue: rabbitmq/rabbitmq-cli#336

• rabbitmqctl delete_queue -u failed argument validation due to a typo.

  GitHub issue: rabbitmq/rabbitmq-cli#339

Erlang AMQP 0-9-1 Client

Bug Fixes

• Direct connections (via Erlang distribution) from outside of a RabbitMQ should no longer fail due to
  a dependency on a module that was previously a part of core RabbitMQ broker.

  GitHub issue: rabbitmq/rabbitmq-erlang-client#91

Auth Backend Cache Plugin

Bug Fixes

• Virtual host endpoint requests were not cached.

  GitHub issues: rabbitmq/rabbitmq-auth-backend-cache#20,
  rabbitmq/rabbitmq-auth-backend-cache#24
