Bug #1640

Loading same plugin twice from different pathes

If two or more (2+) plugin paths are configured, and a specific plugin is available in 2+ of these plugins paths, rsc tries to load this plugin 2+ times, resulting in duplicate entries.
Instead rsc should just load the first occurrence of a plugin (in the order given by the plugin path configuration).

I just looked at the code and there is a unit tests that actually tests that one path overrides another one: PluginTest::testPathOverriding. There would be an exception if the plugin was loaded twice. Could you please explain in more detail what happens in your case?

It seems, that you already adressed this issue in a3932651bd, but did not close it. ;)

But then the description is actually wrong. ;) That commit addressed the issue that the configuration requested to load the same plugin twice, and not that two version of the plugin in different folders existed.

Daniel, I remember, that this issue came up in a setup of yours, where you had the toolkit plugin path configured and a local plugin path with a locally built plugin.
Any chance, that you could reproduce the issue you had back then? Otherwise I would consider this issue resolved.
