unpack failed --- is my repos broken?

unpack failed --- is my repos broken?

[Ivan Uemlianin]

Dear All

I have several git repositories on a server, with which I'm 
communicating using smart-http.  Push and pull is all going fine.  Until 
this morning, one of the repositories is not allowing pushes:

     $ git push
     Password: ...
     Counting objects: 5, done.
     Delta compression using up to 2 threads.
     Compressing objects: 100% (3/3), done.
     Writing objects: 100% (3/3), 410 bytes, done.
     Total 3 (delta 2), reused 0 (delta 0)
     error: unpack failed: unpack-objects abnormal exit

Other repositories on the same server (and under the same /var/www/git/ 
directory) are working fine.

I have googled around and this doesn't seem to be an uncommon problem, 
but I haven't found a solution.

Does the above mean this repository is broken and I should rescue or 
replace it (as in "How to fix a broken repository?" on the git wiki [1])?

Is smart-http not entirely reliable?  In which case what is the 
preferred way to communicate remotely (we need to push as well as pull; 
there are a very small number of active developers)?

With thanks and best wishes

Ivan

I'm not entirely sure why the error is occuring, but the preferred way
to communicate is over SSH. You can use the git protocol for anonymous
pulling (but not pushing).

ssh communication not working

Dear All

Thank you for your comments.  I apologise for my delayed response.

I can't remember why I set up smart-http.  There was a good reason at 
the time, but it's possible that the reason is no longer in effect.

I tried cloning over ssh and got an error:

     $ git clone ivan@myserver.com:/path/to/git/myproject.git
     Initialized empty Git repository in /Users/ivan/.git/
     ivan@85.92.88.62's password: ...
     bash: git-upload-pack: command not found
     fatal: The remote end hung up unexpectedly

I have ssh access to the server, but it's possible that I haven't set up 
the server to serve git over ssh.  Please could someone point me to the 
appropriate place in the documentation?  The command git upload-pack is 
available on the client and on the server.

With thanks and best wishes

Ivan

You don't have git-upload-pack in non-interactive $PATH (it is not the same
as $PATH for interactive logins). Edit ~/.bashrc on remote side?

Aha!  It works!

Dear Ilari

Thanks very much!

Have you checked for repository corruption on the local side? You
might be pushing bad stuff to the server.

Dear All

Thank you for your comments.  I apologise for my delayed response.

I think the local side is not the problem:  if I do a fresh clone, then 
when I try a push I get the same error.

For the moment I have deleted and recreated the git repos on the server 
(tedious but quick), and all seems well.  Is this an occasional fault I 
can expect with the smart-http backend?

See query about ssh under separate title.

With thanks and best wishes

Ivan
