When some a patch gets uploaded, @gerritbot adds the Patch-For-Review tag. @Maintenance_bot removes the tag, when the patch gets merged, but not when the patch gets abandoned. Thus there are tasks with the tag, but without actually having patches for review (e.g. T275819).
Would it be possible to remove the tag also when the patch is abandoned?
The code at least in paper supports abandoned patches too: https://github.com/Ladsgroup/Phabricator-maintenance-bot/blob/master/patchforreview_remover.py#L43
Might be that the formatting of the message changed? I'll check.
Done. https://github.com/Ladsgroup/Phabricator-maintenance-bot/commit/2cbe8ea3af24b57df224ee701ea269b4b86b6ec8 In future this won't happen again.
