wishlist; unify behavior while cloning non-bare repos over http to be in line with ssh/local

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Dear Git Folks,

Originally this issue was mentioned in previous thread [1], and I have decided
to bring it into a separate thread.  ATM there is a dichotomy in git behavior
between cloning non-bare repos:  if I clone over ssh or just locally by
providing url without trailing /.git, git senses for /.git and works just fine
with ssh or local repositories, but fails for "dummy" http ones, the demo
script is here [2] which produces output listed below.  From which you can see
that  cloning using http URL to the repository without /.git fails (git version
2.8.1, Debian).  As it was noted in [1], concern could have been to not
traverse website since could lead to dangerous places.  But .git is under
originating url directory, as well as info/ or HEAD or any other object
accessed by git, so IMHO this concern is not a concern.

So do you think that cloning from  http urls could be adjusted so git senses
for presence of .git/ subdirectory if originating url is missing necessary
/info/refs?.... ?  That would make behavior uniform and help us and users in
many use-cases IMHO (in particular with relative paths to submodules as in
[1])

Thank you in advance, and please maintain CC
