更新内容
Core Server
Bug 修复
Logging to
amq.rabbitmq.logexchange is available again as a logging mechanism. Note that
the user must opt-in by settinglog.exchange = truein the config file.GitHub issue: rabbitmq-server#1456
During node boot, the logger will temporarily accept a much higher maximum rate so that no messages are dropped.
GitHub issue: rabbitmq-server#1471
Plugin activation could hang if a plugin's channel interceptor failed to activate with an exception.
GitHub issue: rabbitmq-server#1477
During node boot, virtual host that are not yet initialised could be queried for status, which
resulted in log noise.GitHub issue: rabbitmq-server#1472
增强
Internal authN backend will now prohibit logins with blank passwords. Such attempts
are usually made by mistake because a passwordless user that was meant to authenticate
using x509 (TLS) certificates was not configured to use the correct authentication
mechanism.Note that the same behavior can already be achieved using a credential validator, so this is
just an extra safety measure.GitHub issue: rabbitmq-server#1465
管理插件
Bug 修复
Definition import now stores global parameters in a way that the MQTT plugin expects.
GitHub issue: rabbitmq-management#528
User update form now successfully updates tags for passwordless users (or if the password is cleared at the same time).
GitHub issue: rabbitmq-management#533
增强
Requeue is now the default option in the Get Messages section.
Contributed by @dparkinson.
GitHub issue: rabbitmq-management#542
For passwordless users, the "no password" option on the user editing form is now preselected.
GitHub issue: rabbitmq-management#537
LDAP AuthN/AuthZ 后端插件
Bug 修复
More config keys are now supported via new style config format.
GitHub issue: rabbitmq-auth-backend-ldap#78
Peer Discovery Consul 插件
When a node registers with Consul it will now set its initial health check status to
passing.
Previously the node would be in thecriticalstate until it first reported its health for the
first time (in 15 seconds with default settings), which could prevent its peers from discovering it.Kudos to @andersenleo for investigating this issue and recommending a solution.
GitHub issue: rabbitmq-peer-discovery-consul#8
