-----------------------------
> Automatic loading of conflicting plug-ins
> -----------------------------------------
>
> Key: QPID-2572
> URL: https://issues.apache.org/jira/browse/QPID-2572
> Project: Qpid
> Issue Type: Improvement
> Components: C++ Broker
> Affects Versions: 0.7
> Reporter: Alan Conway
> Assignee: Alan Conway
> Priority: Minor
>
> Thread http://www.mail-archive.com/dev@qpid.apache.org/msg08762.html may
> result in an alternate clustering plugin that uses the same amq.failover
> mechanism as the existing cluster plugin - well and good that's what plugins
> are for. The new plugin could not be loaded at the same time as the existing
> cluster plugin as they'd conflict over setting amq.failover exchange, also
> not surprising.
> However our existing plugin loading scheme is:
> - install every plugin in lib/qpid/daemon
> - by default load every plugin from lib/qpid/daemon
> This breaks if we have conflicting plug-ins.
> I see 3 solutions:
> 1. Put conflicting plugins in a new dirctory say lib/qpid/daemon_optional.
> User must load these explicitly in config if wanted.
> 2. Ship a default config with
> no-module-dir=yes # disable default loading
> load-plugin=foo # for all foo we want to load by default.
> 3. Change the default module-dir to be none, load no plugins by default. Ship
> a config file with explict load-plugin=foo for all foo we want to load by
> default.
> I prefer 3 as it simplifies things a little and maintains the "0 config gives
> sensible behavior" principle - 0 config means no plugins as opposed to try to
> load conflicting plugins. It does mean users would have to change their
> existing configs.
> See also QPID-2571 which would simplify the default configs proposed in 2 & 3
