Release: RabbitMQ 3.0.0
|

|
server
|
|
------
|
|
bug fixes
|
|
25195 prevent mirror being promoted before it has received all
|
|
messages from dying master, which subsequently caused it to crash
|
|
25202 fix race at mirror startup causing process leak and other problems
|
|
25216 prevent excessive memory use when recovering large durable queues
|
|
25226 prevent mirrors leaking memory when using persistence and confirms
|
|
25260 ensure messages that expire while the broker is stopped are
|
|
dead-lettered correctly
|
|
25198, 25185, 25200 ensure "redelivered" flag set correctly on HA
|
|
queue failover
|
|
25053 ensure statistics event emission does not prevent fsync
|
|
25215 ensure rapid declaration of many mirrored queues does not overload
|
|
Mnesia
|
|
25000 don't write a PID file when -detached is specified as it will
|
|
not be right
|
|
25263 fix channel number in error message if rabbit_writer crashes

|
|
one channel sees many queues deleted
|
|
|
|
enhancements
|
|
24991 correctly enforce AMQP frame_max. Note that some buggy clients
|
|
do not frame messages correctly; as of 3.0.0 these clients
|
|
will be rejected if they attempt to send a message large than
|
|
frame_max (by default 128k).
|
|
24908 allow queue mirroring to be defined by broker-wide policy, not
|
|
queue declaration, and add "exactly" mode
|
|
24196 dynamic runtime configuration mechanism (parameters)
|
|
24914 rewrite of rabbitmqctl clustering commands for greater user
|

|
|

|
|
25227 provide information if a network partition has occurred
|
|
(reported in 'rabbitmqctl cluster_status')
|
|
24792 improve plugin startup procedure:
|
|
- "rabbitmqctl wait" will not return until plugins have started
|
|
- Windows service users no longer need to reinstall service
|
|
after enabling plugins
|
|
24971 enable heartbeats by default
|
|
24719 ensure broker starts and rabbitmq-plugins works when plugin
|
|
dependencies are missing
|
|
25164 give better error message when attempting to use a queue which
|
|
is on a down node
|
|
25086 improve error reporting for framing errors
|
|
25262 sort the output of rabbitmqctl list_*
|
|
23935 reverse DNS lookups for connection info items (disabled by
|
|
default, see the 'reverse_dns_lookup' configuration item)
|
|
25193 expose count of non-blocked consumers as a queue info item
|
|
24998 make memory / disk alarms easier to spot in log files
|
|
24956 provide better log messages when heartbeat timeouts occur
|
|
24919 check flags passed to rabbitmqctl match the subcommand
|
|
25244 cope if clients set malformed "x-death" headers
|
|
24867 reject attempts to declare queues with x-expires or
|
|
x-message-ttl greater than 2^32 milliseconds since this will
|
|
not work
|
|
|
|

|
|
|

Upgrading
|
|
=========
|
|
To upgrade a non-clustered RabbitMQ from release 2.1.1 or later, simply install
|
|
the new version. All configuration and persistent message data is retained.
|
|
|
|
To upgrade a clustered RabbitMQ from release 2.1.1 or later, install the new
|
|
version on all the nodes and follow the instructions at
|
|
https://www.rabbitmq.com/clustering.html#upgrading .
|
|
|
|
To upgrade RabbitMQ from release 2.1.0, first upgrade to 2.1.1 (all data will be
|
|
retained), and then to the current version as described above.
|
|
|
|
When upgrading from RabbitMQ versions prior to 2.1.0, the existing data will be
|
|
moved to a backup location and a fresh, empty database will be created. A
|
|
warning is recorded in the logs. If your RabbitMQ installation contains
|
|
important data then we recommend you contact support at rabbitmq.com for
|
|
assistance with the upgrade.
