Subject: git gc seems to break --symbolic-full-name
Message-ID: <234492d7-7fd6-f847-8b85-010732ff43b6@list.ru>

Hello.

I do the following:

$ git rev-parse --symbolic-full-name devel
refs/heads/devel
$ ls -l .git/`git rev-parse --symbolic-full-name devel`
-rw-rw-r-- 1 stas stas 41 июл 21 15:05 .git/refs/heads/devel

This is fine. But after git gc:

$ git rev-parse --symbolic-full-name devel
refs/heads/devel
$ LC_ALL=C ls -l .git/`git rev-parse --symbolic-full-name devel`
ls: cannot access '.git/refs/heads/devel': No such file or directory

This is because after git gc there is nothing in .git/refs/heads:

$ LC_ALL=C ls -l .git/refs/heads/
total 8
drwxrwxr-x 2 stas stas 4096 Jul 31  2013 feature
drwxrwxr-x 2 stas stas 4096 Dec 23  2016 pr

I prepend the path with .git above just as an
example: the same happens with rev-parse --git-path.

So I wonder if it is an expected behaviour for
--symbolic-full-name to return the invalid pathes?
If so, how can I get the path to the needed head file?
I use that for dependency tracking.
