RabbitMQ 3.7.8 RC3

RabbitMQ 3.7.8-rc.3 a maintenance release. It focuses on bug fixes and
further improves Erlang/OTP 21 compatibility.

Upgrades and Compatibility

This release has no known incompatibilities with earlier 3.7.x releases.

Upgrading to Erlang 21.0

When upgrading to this release and upgrading Erlang to 21.0 at the same time, extra care has to be taken.
Since CLI tools from RabbitMQ releases older than 3.7.7 will fail on Erlang 21, RabbitMQ must be upgraded before Erlang.

Documentation Guides and Change Log

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

RabbitMQ 3.7.6

RabbitMQ 3.7.6 a maintenance release that primarily includes bug fixes.

Upgrades and Compatibility

This release includes one potential incompatibility with earlier 3.7.x releases. Only systems
that use a high number (hundreds) of queue priorities are affected.

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

  • Max priority cap for queues is now enforced and set to 255. Applications that rely on a higher number of priorities will break.
    Such applications must be updated to use no more than 255 priorities.

    GitHub issue: rabbitmq-server#1590

  • Bulk deletion of exclusive queues when their owning connection closes has been optimized.

    GitHub issues: rabbitmq/rabbitmq-server#1566, rabbitmq/rabbitmq-server#1513

Enhancements

  • On Erlang 20.2.3 or later, more optimal memory allocators will be used. On some workloads that leads
    to significant reduction in node's RAM consumption. The change is workload-specific, however, on the workloads
    tested that do introduce a negative effect (more RAM used) the difference was very small (about 1%).

    It is possible to go back to the previous settings, +MBas aoffcbf +MHas aoffcbf +MBlmbcs 5120 +MHlmbcs 5120 +MMmcs 10,
    by specifying them in the RABBITMQ_SERVER_ADDITIONAL_ERL_ARGS environment variable.

    On Erlang/OTP releases older than 20.2.3 there will be no default changes.

    GitHub issue: rabbitmq/rabbitmq-server#1604

  • Logging to Syslog without 3rd party plugins.

    GitHub issue: rabbitmq-server#1600

  • connection.closed events now include client-provided connection name and more client details.
    That information is in turn available via the rabbitmq_event_exchange.

    GitHub issue: rabbitmq-server#1596

CLI Tools

Enhancements

  • await_online_nodes <count> [--timeout <timeout>] is a new command that will wait until the target
    node's cluster has at least <count> nodes. The command supports a timeout. It is meant to simplify
    cluster provisioning automation and can be used as the very first check performed after starting a node.

    Note that the command requires at least one node to be running and reachable.

    GitHub issue: rabbitmq-cli#235

  • rabbitmq-diagnostics ping [--node <target> --timeout <timeout>] is a new minimalistic health check command.
    It only verifies if the target node is up, registered with epmd and accepts/authenticates CLI tool connections.
    It fills the gap between rabbitmq-diagnostics node_health_check, which performs a lot of checks, take a lot more time
    and is fairly opinionated in what it does. ping is more suitable in environments where
    failing aliveness checks will result in node restarts, namely Kubernetes.

    GitHub issue: rabbitmq-cli#253

Management and Management Agent Plugins

Bug Fixes

  • Queue metrics could be missing after a node restart or plugin [re-]enablement.

    GitHub issue: rabbitmq/rabbitmq-management-agent#58

  • rabbitmqadmin now correctly percent-encodes spaces in connection names.

    GitHub issue: rabbitmq/rabbitmq-management#576

  • When creating a new vhost, user permissions will only be granted to the users that exist in the
    internal database. If an external authentication/authorization service is used, the step is skipped.

    GitHub issue: rabbitmq-management#531

  • Virtual host imported from definitions or created via HTTP API will explicitly await for the vhost to initialise
    on all cluster nodes.

    GitHub issue: rabbitmq/rabbitmq-management#575

LDAP Plugin

Bug Fixes

  • LDAP connection pool now correctly purges connections in more failure scenarios (e.g. LDAP server restart)

    GitHub issue: rabbitmq-auth-backend-ldap#92

HTTP Authentication/Authorization Plugin

RabbitMQ 3.6.16

RabbitMQ 3.6.16 is a maintenance release that primarily includes selected backports from
the 3.7.x series. Users of earlier 3.6.x releases
are recommended to upgrade to a 3.7.x release, e.g. 3.7.6.

Upgrades and Compatibility

See the Upgrades documentation guide for general
documentation on upgrades.

This release nearly exclusively contains backports of bug fixes, optimisations and small enhancements
(e.g. safer defaults) from the 3.7.x series. Some of them are potentially breaking but
should only affect a very small percentage of users. They are:

  • The max 255 priority cap is now enforced at all levels
  • Default rabbit.channel_max value is now about 2K, a much safer value than 65K used previously
  • Default idle LDAP connection timeout is now 300 seconds instead of infinity

This release has no other known incompatibilities with versions 3.6.7 through
3.6.15. See the upgrade and compatibility sections in the 3.6.7 release
notes

if upgrading from an earlier release.

3.6.x Series Support Timeline

Please read this note on RabbitMQ 3.6.x series support
timeline
.

Core Server

Bug Fixes

  • Queue master locator min-masters incorrectly calculated the number of masters.

    GitHub issue: rabbitmq-server#1519

  • Maximum supported number of queue priorities (255) is now enforced.

    GitHub issue: rabbitmq-server#1590

Enhancements

  • On Erlang 20.2.3 or later, more optimal memory allocators will be used. On some workloads that leads
    to significant reduction in node's RAM consumption. The change is workload-specific, however, on the workloads
    tested that do introduce a negative effect (more RAM used) the difference was very small (about 1%).

    It is possible to go back to the previous settings, +MBas aoffcbf +MHas aoffcbf +MBlmbcs 5120 +MHlmbcs 5120 +MMmcs 10,
    by specifying them in the RABBITMQ_SERVER_ADDITIONAL_ERL_ARGS environment variable.

    On Erlang/OTP releases older than 20.2.3 there will be no default changes.

    GitHub issue: rabbitmq/rabbitmq-server#1604, rabbitmq/rabbitmq-server#1612

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

    GitHub issue: rabbitmq-server#1501

  • ha-promote-on-failure is a new mirrored queue setting that's similar to ha-promote-on-shutdown
    but for unexpected master termination.

    GitHub issue: rabbitmq-server#1578

  • 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.:

[
  {rabbit, [
    {channel_max, 4000}
  ]}
].

GitHub issue: rabbitmq-server#1593

Management Plugin

Bug Fixes

  • Eliminated unnecessary encoding conversions that could lead to increased memory consumption.

    GitHub issue: rabbitmq-management#550

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

    GitHub issue: rabbitmq-management#568

  • rabbitmqadmin incorrectly encoded spaces in connection name values

    GitHub issue: rabbitmq-management#579

  • HTTP API stats documentation used incorrect field names.

    GitHub issue: rabbitmq-management#561

Enhancements

LDAP Plugin

Bug Fixes

Upgrading

To upgrade a non-clustered RabbitMQ simply install the new version. All
configuration and persistent message data are retained. When upgrading
using definitions export/import from versions earlier than 3.6.0, see
http://rabbitmq.com/passwords.html.

To upgrade a RabbitMQ cluster, follow the instructions in RabbitMQ
documentation
