Hi @gnuletik and @yomguy. This bug has been caused by version change of Aubio pitch in this commit.

I indeed set aubio_pitch version to 0.4.7 when I added version field on models.Processor without being sure of the write one to give (depend on witch aubio algo/decoding version we use, right?)

@yomguy has corrected it to 0.4.6 in aubio_pitch.pyplugin, thanks for that.

However, from the point of view of sandbox: a new plugins is now available with same processor id (i.e. pid) but a different version.

I deleted the former aubio_pitch 0.4.7 processor in sandbox's DB as it does not refer to a real plugin anymore so it temporary fixes the bug.

@yomguy, what is the best short term and the best preferable long term solutions to manage processors unicity regarding there pid and version:

• does 2 processor with same pid but different version are allowed to live together? (if yes, a reliable plugin file name should be specified E.g: aubio_pitch_0.4.6.py)
• should models.Processor pid and version be unique_together and at then all Processors.objects.get(pid=...) should be added a version (or replace them with a Processors.get_last_version(pid=...) with a version format spec)
• about Processors URL as discuss in this issue: should they include version: E.g.: /timeside/api/processors/aubio_pitch/0.4.6/
• while app is run, all plugins that does not have a processor with same pid and version will be created. Should any current processor that does not refer anymore to an available plugin be deleted?
