building & packaging
|
|||
|
|
--------------------
|
|||
|
|
bug fixes
|
|||
|
|
- correct locations of libraries et al on 64bit rpm systems
|
|||
|
|
|
|||
|
|
enhancements
|
|||
|
|
- detect upgrade from pre-1.5.0 and warn/ask user (under debian & rpm)
|
|||
|
|
- comply with debian and rpm packaging policies and guidelines
|
|||
|
|
- prevent accidental executing of scripts as non-root user under
|
|||
|
|
debian & rpm
|
|||
|
|
- read /etc/default/rabbitmq in scripts on Unix-y systems, with env
|
|||
|
|
vars taking precedence over vars set in that file and the defaults
|
|||
|
|
used by the scripts
|
|||
|
|
- prefix env vars with 'RABBITMQ_'
|
|||
|
|
- allow script execution from anywhere (not just the scripts' dir)
|
|||
|
|
- add script & instructions to start RabbitMQ as a Windows service
|
|||
|
|

|
|||
|
|
- automatic log rotation under debian & rpm
|
|||
|
|
- use simplejson.py instead of json.py in code generation, thus
|
|||
|
|
allowing use of Python 2.6

Upgrading
|
|||
|
|
=========
|
|||
|
|
|
|||
|
|
The database schema has changed between RabbitMQ-1.4.0 and this
|
|||
|
|
release. When the RabbitMQ server detects the presence of an old
|
|||
|
|
database, it moves it to a backup location, creates a fresh, empty
|
|||
|
|
database, and logs a warning.
|
|||
|
|
|
|||
|
|
If your RabbitMQ installation contains important data, such as user
|
|||
|
|
accounts, durable exchanges and queues, or persistent messages, then
|
|||
|
|
we recommend you contact rabbitmq-sales@pivotal.io for assistance with the
|
|||
|
|
upgrade.
