Subject: guess default branch from HEAD
X-Git-Url: https://gitweb.ps.run/ps-cgit/commitdiff_plain/d711de55280c3c9c10cfda4e24c8f3b3015217b2?ds=sidebyside;hp=d711de55280c3c9c10cfda4e24c8f3b3015217b2

guess default branch from HEAD

This is a saner alternative than hardcoding the default branch to be
"master". The add_repo() function will now check for a symbolic ref in
repo_path/HEAD. If there is a suitable one, overwrite repo->defbranch
with it. Note that you'll need to strip the newline from the file (->
len-17).

If HEAD is a symbolic link pointing directly to a branch below
refs/heads/, do a readlink() instead to find the ref name.
