RE: [PATCH] git-submodule: Instead of using only annotated tags, use any tag found in .git/refs/tags
Hello Junio,
You're right and there might be no tag at all, thus --contains might return an undefined. In the spirit of best effort maybe we should try --all (which I don't think that can fail and it will return something more relevant then undefined, i.e. the branch of the commit) if --contains returns undefined. I'll submit a patch to reflect this. Opinions?
While playing with git-describe I noticed that the --all option is maybe not trying first to find a tag as the man page suggests but it goes directly for .git/refs. Here is some output from my git repo clone with yesterday's head on the master branch:
$ git-describe aeb59328453cd4f438345ea79ff04c96bccbbbb8 v1.5.2.2-549-gaeb5932
$ git-describe --all aeb59328453cd4f438345ea79ff04c96bccbbbb8 heads/master
Do you think we want to fix that? If yes, I could look into it and submit a patch.
Cheers, Emil.

Certainly that is an improvement, as $revname is purely for commenting and not being able to describe it is not an excuse to fail the command.
But there may not be any tag at all. How about something like this on top?
