# get the repo name
my $repo = shift;
$repo =~ s/\.git$//;
# IMPORTANT NOTE: to do any of this inside a hook, you should just use
# $ENV{GL_REPO}, since it's guaranteed to be set to the right value



# to do a "level 1" check (repo level -- not branch level), do this:
my ($perm, $creator) = check_access($repo);
# you can pass in any repo name you wish instead of the active repo

# the first return value looks like one of these, so you can just check for
# the presence of "R" or "W" and be done:
#   _____R___W_
#   _____R_____
#   ___________

# The second value is "<gitolite>" for a normal repo,  an actual username for
# a wildrepo, or "<notfound>" for a non-existent repo.



# to do a "level 2" check (branches), do something like this
my $ret = check_access($repo, 'refs/heads/foo', 'W', 1);
# the 2nd argument must be a *full* refname (i.e., not "master", but
# "refs/heads/master").  The 3rd argument is one of W, +, C, or D.  The 4th
# argument should be any non-false perl value, like 1.

# the return value may look like this:
#   refs/.*
# or perhaps this, if you were denied
#   DENIED by fallthru

# NOTE: do NOT pass "R" as the 3rd argument.  It will seem to work because
# you're merely testing the permissions in this code, but an *actual* "git
# fetch" for even a DENIED ref will succeed if the user has read access to at
# least one branch.  This is because the information on what ref is being read
# is not made available externally in any useful way (the way the "update"
# hook gets its arguments when a push happens).
