git-p4 can map a "git move" operation to a Perforce "move" operation. But by default this is disabled. You then end up with a P4 commit where the file is deleted, and a fresh file is created with the same contents at the new location at revision #1. Rename detection gets enabled either with the "-M" option, or with some config variables, git-p4.detectCopies and git-p4.detectRenames. I've been tripped up by this, and I actually know about it, and I know other people have been as well. Should we switch the default over so that it's enabled by default? I can't think of any reason why you wouldn't want it enabled. I think the rename code was first introduced around 2011 by Vitor. Another option is to add a warning, but people just ignore warnings! Thanks! Luke
