Remove old flagrequest when manually unflagging

[jelly]

When manually unflagging the old flagrequest is not removed while it should be.

Number of flag requests can be obtained by:

>>> from packages.models import FlagRequest
>>> FlagRequest.objects.count()

Steps:

• Check the number of flagged packages
• Flag a package
• Unflag the same package
• Number of flagged packages should be the same.

Queries for removing old flagrequests in postgresql

Listing old flagrequests

SELECT fr.id,fr.created,fr.pkgbase,fr.pkgver,fr.pkgrel,fr.epoch FROM packages_flagrequest as fr INNER JOIN packages as ps ON (fr.pkgbase = ps.pkgbase AND fr.pkgver != ps.pkgver AND fr.repo_id = ps.repo_id) ORDER BY fr.created desc;

Deleting old flagrequests

DELETE FROM packages_flagrequest as fr USING packages as ps WHERE fr.pkgbase = ps.pkgbase AND fr.pkgver != ps.pkgver AND fr.repo_id = ps.repo_id;

Missing are the packages of with the pkgbase does not exists anymore in the repos.

Remove packages. This isn't handled by our code yet.

select id,pkgbase from packages_flagrequest as fr where not exists (select * from packages where fr.pkgbase = packages.pkgbase)

[jelly]

Correct query to fetch to be removed packages.

select fr.id, fr.pkgbase, fr.created, fr.pkgver from packages_flagrequest fr left outer join packages p on p.pkgbase = fr.pkgbase and p.repo_id = fr.repo_id and p.flag_date is not null where p.pkgbase is null;

[jelly]

One case, unflag for $pkg can be simply fixed by the following code in def unflag(req, ...):

     FlagRequest.objects.filter(pkgbase=pkg.pkgbase,
                                repo__name__iexact=repo,
                                pkgver=pkg.pkgver,
                                epoch=pkg.epoch).delete()

But it will also remove a FlagRequest when it's a split package which should not be done. So the code still has to check if it's a split package and only remove it when it's the last split package left.

Also it seems that [testing] => [core] moves are not handled and aren't removed as well.

Commit 7d162a0 should handle deletions of packages.
