RabbitMQ - Trying to start after upgrade with missing plugins.
Fredrik Sörensson
Hello.
I hit a small issue every time I upgrade RabbitMQ in my lab environment. It would probably seldom hit a production environment. But, on my lab machine I sometimes test community plugins etc. When I do an upgrade, the community plugins are removed/not migrated, which is fine. However, they are still listed in the enabled_plugins file, so RabbitMQ won’t start, and it gives this inconspicuous error:
=INFO REPORT==== 1-Mar-2016::17:11:52 ===
Error description:
{error,{"no such file or directory","rabbitmq_test.app"}}
However, when I list the plugins, the offending plugin is not listed:
C:\Program Files\RabbitMQ Server\rabbitmq_server-3.6.0\sbin>rabbitmq-plugins.bat
list

Instead I manually edit the enabled_plugins file and remove the plugin.
Feature requests from me would be that:
- RabbitMQ starts and logs that a plugin was not found and therefore not loaded –or– RabbitMQ does not start but that the log message explicitly mentions that it was a plugin that failed to load.
- Rabbitmq-plugins.bat lists even missing plugins, but mark them as broken, so I can disable them using the tool.
