RabbitMQ 3.7.8 发布，Erlang 的 AMQP 开源实现

RabbitMQ 3.7.8 发布了，这是一个维护版本，侧重于错误修复并进一步提高了 Erlang/OTP 21 的兼容性。

更新如下：

Core Server

Bug Fixes

• Virtual host (specifically binding) recovery has been optimized.

  GitHub issue: rabbitmq/rabbitmq-server#1650

• A binding removal optimization was reverted because it could result in custom exchange type state not cleaned up

  as plugin authors intended.

  GitHub issue: rabbitmq-server#1691

• A queue sync operation now can be cancelled when a resource alarm is in effect on the receiving node.

  GitHub issue: rabbitmq/rabbitmq-server#1636

• Inter-node communication port (a.k.a. distribution port) unintentionally used an excessively large

  buffer size (1.2 GB instead of 128 MB). Kudos to Chris Friesen for noticing and reporting this.

  GitHub issue: rabbitmq/rabbitmq-server#1659

• More idempotent binding removal.

  When transactions that removed bindings were rolled back and retried, the code

  that performed the deletion could fail with a misleading assertion failure,  {error, not_found} .

  GitHub issue: rabbitmq-server#1689

• A resource alarm triggered during boot could prevent node from starting.

  GitHub issue: rabbitmq/rabbitmq-server#1644

• Environments with high queue or channel churn could run into an exception in local process group.

  GitHub issue: rabbitmq/rabbitmq-server#1699

• Priority queues no longer fail with an exception when used together with other rabbit_backing_queue
  behaviour implementations.

  Contributed by Matteo Cafasso.

  GitHub issue: rabbitmq-server#1669

• Syslog configuration parameters could be rejected by config validator.

  GitHub issue: rabbitmq/rabbitmq-server#1639

• rabbitmq-echopid.bat now loads  rabbitmq-env.bat correctly.

  GitHub issue: rabbitmq/rabbitmq-server#1642

Enhancements

• Improved config file validation and loading. For example, advanced.config now can be used

  without the main  rabbitmq.conf config file.

  GitHub issue: rabbitmq-server#1671

• On Erlang/OTP 21 Syslog server now can be configured using a hostname (not just an IP address).

  GitHub issue: rabbitmq/rabbitmq-server#1658

• rabbitmqctl rename_cluster_node documentation improvements.

  GitHub issue: rabbitmq/rabbitmq-server#1641

CLI Tools

Bug Fixes

• Policies were unintentionally excluded from rabbitmqctl report output.

  Contributed by Ayanda Dube.

  GitHub issue: rabbitmq/rabbitmq-cli#256

• Global parameters were unintentionally excluded from rabbitmqctl report output.

  GitHub issue: rabbitmq-cli#258

Management Plugin

Bug Fixes

• Virtual host imported from definitions or created via HTTP API will explicitly await for the vhost to initialise

  on all cluster nodes. This change was previously scheduled for  3.7.6 but was only partially applied (didn't have

  any effect on HTTP API clients).

  GitHub issues: rabbitmq/rabbitmq-management#575 ,  rabbitmq/rabbitmq-management#591

• HTTP API connection endpoints returned a duplicate key, node .

  GitHub issue: rabbitmq-management#601

• Response compression wasn't enabled by default for compatible clients.

• Failed login error message now clears automatically after successful login.

  GitHub issue: rabbitmq/rabbitmq-management#609

Enhancements

• Cowboy listener settings now can be configured using new style config file.

  GitHub issue: rabbitmq-management#596

• Cowboy timeouts now can be configured.

  GitHub issues: rabbitmq/rabbitmq-management#594

  GitHub issue: rabbitmq/rabbitmq-management#593

• Switching sections will now scroll to the top of the newly rendered page.

  GitHub issue: rabbitmq/rabbitmq-management#590

Consistent Hashing Exchange Plugin

Enhancements

• Message distribution uniformity has been significantly improved. Jump Consistent Hash is now used for

  the hashing function.

GitHub issue: rabbitmq-consistent-hash-exchange#37

STOMP Plugin

Bug Fixes

• Nodes experiencing very high connection churn could run out of Erlang processes.

  GitHub issues: rabbitmq/rabbitmq-stomp#125 ,  rabbitmq/rabbitmq-server#1640

Web STOMP Plugin

Enhancements

• WebSocket endpoint path is now configurable.

  GitHub issue: rabbitmq-web-stomp#86

MQTT Plugin

  by the user.

  GitHub issue: rabbitmq-amqp1.0-client#10

• TLS version for AMQP 1.0 endpoints now can be configured via a connection URI query parameter.

  GitHub issue: rabbitmq-amqp1.0-client#19

• Specifying a port without a hostname in connection URI is now considered

  to be an unsupported combination and will throw an error.

  GitHub issue: rabbitmq-erlang-client#107

Federation Plugin

Bug Fixes

  GitHub issue: rabbitmq-erlang-client#107

Peer Discovery Etcd Plugin

Bug Fixes

• Node name is now correctly extracted from the keys returned by

  etcd even when key prefix includes slashes.

  GitHub issue: rabbitmq-peer-discovery-etcd#14

Debian Package

Bug Fixes

• Package installation scripts will make sure that the /etc/rabbitmq directory is readable.

  GitHub issue: rabbitmq-server-release#72

RPM Package

Bug Fixes

• Package installation scripts will make sure that the /etc/rabbitmq directory is readable.

  GitHub issue: rabbitmq-server-release#72

  by the user.

  GitHub issue: rabbitmq-amqp1.0-client#10

  compatibility with AMQP 1.0 implementations (e.g. Azure ServiceBus) that expect it to be set.
