read_branches_file ()

["H.Merijn Brand" <h.m.brand@xs4all.nl>]

I'm (again) trying to port git-1.5.4 to HP-UX, and I've already got rather
far, but I'm hitting some stuff I cannot explain.

t5405-send-pack-rewind.sh fails the 'git fetch .. master:master' part in
the setup, as deep down, read_branches_file () is called with in remote
the name "..".

The file that it tries to open using git_path () is ".git/branches/.."
That is weird. That is not a file, but a dir. "../.git/branches" would
be more logical, but whatever. HP-UX 11.00 will gladly return a valid
FILE * for opening a directory with fopen (), which, when read, will
return anything but what is expected. So, maybe read_branches_file ()
should be protected against opening anything but files. Maybe with some
stat () and S_ISREG ()'s.

Or has something gone wrong earlier on?

In my case, the returned url is 'l', which cannot be opened:

fatal: 'l': unable to chdir or not a git archive
fatal: The remote end hung up unexpectedly

which is cast from upload-pack.c:main ()
