RabbitMQ 3.7.8-rc.4 发布，多协议消息代理

RabbitMQ 3.7.8-rc.4 已发布，该版本侧重于 Bug 修复，并进一步改进 Erlang/OTP 21 的兼容性。

RabbitMQ 是由 LShift 提供的一个 Advanced Message Queuing Protocol (AMQP) 的开源实现，由以高性能、健壮以及可伸缩性出名的 Erlang 写成，因此也是继承了这些优点。

更新内容如下：

Core Server

Bug Fixes

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

• A binding removal optimization was reverted because it could result in custom exchange type state not cleaned up as plugin authors intended.

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

• 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.

• 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} .

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

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

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

• Syslog configuration parameters could be rejected by config validator.

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

Enhancements

• Improved config file validation and loading. For example, advanced.config now can be used without the main  rabbitmq.conf config file.

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

• rabbitmqctl rename_cluster_node documentation improvements.

CLI Tools

Bug Fixes

• Policies were unintentionally excluded from rabbitmqctl report output.

• Global parameters were unintentionally excluded from rabbitmqctl report output.
