custom backend: please fix multiple groups support

[yarda]

I.e. support to interpret: 3_01 by regex: (\d*)(\d)_(\d) Which would result in e.g.: [(u'3', u'0', u'1')] Which in turn would be interpreted as: 3.0.1

I think this would allow more flexible matching. E.g. uhd upstream has some really strange version presentation, e.g.: release_003_010_001_000

The following regex: release[0]?[0]?(\d+)[0]?[0]?(\d+)[0]?[0]?(\d+)[0]?[0]?(\d+) would turn it into nice: 3.10.1.0

Of course upstream could fix it, but in case they cannot/don't want, etc. such flexibility in anitya would be great.

Hmm, it seems there is already support for it in the code: https://github.com/fedora-infra/anitya/blob/master/anitya/lib/backends/__init__.py#L334-L336

Now investigating why it doesn't work for me.

[yarda]

Hmm, no idea what's wrong, it seems OK in the code, I created the following: https://release-monitoring.org/project/12572/edit By clicking on "test check" or "full check" nothing happens. Maybe there is different bug.

Also the following appeared in Fedora when I tried to enable the version check in pkgdb: hotness tried to map uhd to an upstream project, but failed: "Could not determine backend for http://code.ettus.com/redmine/ettus/projects/uhd/wiki" http://code.ettus.com/redmine/ettus/projects/uhd/wiki ( triggered by https://apps.fedoraproject.org/notifications/jskarvad.id.fedoraproject.org/irc/25141 )

@yarda Hey, thanks for reporting this. I think this might have been a bug that was in 0.10.0 and was fixed in 0.10.1. Right now I'm able to retrieve version "3.10.1.0" from https://release-monitoring.org/project/12572/ so I'm going to close this. Please re-open this issue if it's still a problem somewhere!
