RabbitMQ 3.12.2

Core Server

Enhancements

Free disk space monitor on Windows is now more selective in what errors are
logged.

Bug Fixes

Queue recovery on node restart in certain conditions could run into an exception

file_handle_cache operations are now safer when handling non-existent keys.

Fixed a potential resource leak in at-least-once dead lettering from quorum queues.

CLI Tools

Enhancements

A new command, rabbitmqctl deactivate_free_disk_space_monitoring, can be used to \ 
(temporarily or permanently) disable
free disk space monitoring on a node.

To re-activate it, use rabbitmqctl activate_free_disk_space_monitoring.

AMQP 1.0 Plugin

Bug Fixes

AMQP 1.0 clients that try to publish in a way that results in the message not \ 
being routed
anywhere are now notified with a more sensible settlement status.

Prometheus Plugin

Enhancements

Prometheus scraping API endpoints now support optional authentication.

The plugin now filters out values that are undefined or NaN, simply excluding
them from the API endpoint response.

Previously, if a metric was not computed for any reason (e.g. free disk space monitor
was disabled on the node), its value could end up being rendered as undefined or NaN,
two values that Prometheus scrapers cannot handle (for numerical types such as \ 
gauges).

Management Plugin

Bug Fixes

It was not possible to close a table column selection pane on
screens that had little vertical space.

STOMP Plugin

Bug Fixes

This is a potentially breaking change.

The plugin will now enforce maximum STOMP frame size. Frames larger than that
size will be rejected. The default maximum size is 4 MiB. It can be increased or \ 
decreased:

# increase maximum supported STOMP frame size to 10 MiB
stomp.max_frame_size = 10485760
To reduce it from the default 4 MiB to 2 MiB:

# 2 MiB
stomp.max_frame_size = 2097152

Shovel Plugin

Bug Fixes

Shovel will gracefully stop when its destination (target) does not exist.
Such shovels will then be periodically restarted to retry.

Web MQTT Plugin

Enhacements

It is now possible to opt in to deactivate file handle cache use in the plugin:

web_mqtt.use_file_handle_cache = false

Web STOMP Plugin

Enhacements

It is now possible to opt in to deactivate file handle cache use in the plugin:

web_stomp.use_file_handle_cache = false
