RabbitMQ 3.6.1 RC1 發布

jopen 8年前發布 | 11K 次閱讀

RabbitMQ 是由 LShift 提供的一個 Advanced Message Queuing Protocol (AMQP) 的開源實現，由以高性能、健壯以及可伸縮性出名的 Erlang 寫成，因此也是繼承了這些優點。

AMQP 里主要要說兩個組件：Exchange 和 Queue （在 AMQP 1.0 里還會有變動），如下圖所示，綠色的 X 就是 Exchange ，紅色的是 Queue ，這兩者都在 Server 端，又稱作 Broker ，這部分是 RabbitMQ 實現的，而藍色的則是客戶端，通常有 Producer 和 Consumer 兩種類型。



RabbitMQ 3.6.1 RC1 發布了，下載地址：

https://github.com/rabbitmq/rabbitmq-server/releases/tag/rabbitmq_v3_6_1_rc1

該版本完整的改進內容如下：

Bug Fixes

  • Purging a lazy queue could result in an exception

    GitHub issue: rabbitmq-server#514

  • Channel error could make broker unreachable

    Those errors were misleadingly logged as channel_termination_timeout, which
    the issue really was with unhandled messages from concurrently closed TCP socket process.

    GitHub issue: rabbitmq-server#530

  • (Automatic) deletion of an auto-delete queue could lead
    to blocked channels

    GitHub issue: rabbitmq-server#581

  • Heavy and/or prolonged rabbitmqctl use could exhaust Erlang VM atom table

    GitHub issue: rabbitmq-server#549

  • "Min masters" queue master location strategy could result
    in an error.

    GitHub issue: rabbitmq-server#521

  • Fixed a race condition in pause_minority handling mode.

    GitHub issue: rabbitmq-server#307

  • Significantly reduce possibility of a race condition when
    an exchange is deleted and immediately re-declared, e.g. by a federation
    link.

    This could result in a link operation being blocked, preventing
    nodes from stopping.

    GitHub issue: rabbitmq-federation#7

  • amq.rabbitmq.log messages now have information about originating
    node in message headers

    GitHub issue: rabbitmq-server#595

  • scripts/rabbitmq-env now works with GNU sed 4.2.2

    GitHub issue: rabbitmq-server#592

  • Exceptions in VM memory use calculator no longer affect broker startup

    GitHub issue: rabbitmq-server#328

  • Direct Reply-to capability is now advertised to clients

    GitHub issue: rabbitmq-server#520

Enhancements

  • Paths with non-ASCII characters on Windows are now handled

    RabbitMQ no can be installed into a location with non-ASCII characters,
    e.g. when username contains them.

    GitHub issues: rabbitmq-server#493

  • Configurable number of TCP connection acceptors

    Plus a x10 increase of the default. This helps with workloads where connection
    churn is very high (e.g. all clients are PHP Web apps that cannot maintain
    long-lived connections).

    GitHub issues: rabbitmq-server#528

  • rabbitmqctl cluster_status now includes cluster-wide resource alarm status

    GitHub issue: rabbitmq-server#392

  • Improved rabbitmqctl reset error messages

    GitHub issue: rabbitmq-server#167

  • More unsigned field data types are supported.

    GitHub issue: rabbitmq-server#20

Java client

Enhancements

Bug Fixes

.NET client

Bug Fixes

Federation Plugin

Bug Fixes

  • Significantly reduce possibility of a race condition when
    an exchange is deleted and immediately re-declared, e.g. by a federation
    link

    This rendered federation links dysfunctional.

    GitHub issue: rabbitmq-federation#7

Management plugin

Enhancements

  • Password hashing function is now included in exported definitions

    Those upgrading from versions earlier than 3.6.0 via definitions export
    won't have to temporarily set hashing function to MD5 to ensure export succeeds.

    GitHub issue: rabbitmq-management#117

Bug Fixes

Web STOMP plugin

Bug Fixes

Web STOMP Examples plugin

Bug Fixes

Event Exchange plugin

Bug Fixes

  • Event timestamps are now in seconds, not milliseconds

    Per AMQP 0-9-1 spec. This is not a particularly great choice for events,
    so we will add an optional header with millisecond precision in a future release.

    GitHub issue: rabbitmq-event-exchange#8

JSON RPC plugin

Note: this plugin is deprecated and its use is highly discouraged.
