Git & Paramiko: failed to push some refs to ...

I am writing a Python ssh server using Paramiko. While it is very
powerful software, when using it to push git repositories, I run into
strange errors. The following is git's output on the client machine.

$ git push origin master
Counting objects: 5, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (2/2), done.
Writing objects: 100% (3/3), 263 bytes, done.
Total 3 (delta 1), reused 0 (delta 0)
To git@localhost:/pckprojects/heyworld/
   d83f744..404debd  master -> master
error: failed to push some refs to 'git@localhost:/pckprojects/heyworld/'

From the server side I have enough print statements to see the entire
transaction, which looks something like this:

git-receive-pack /home/www/data/project/heyworld/

CLOSE CONNECTION

This looks healthy to me, but I'm of course not that familiar with the
details. In addition, as far as I can tell, master does in fact get
updated and everything properly, so I have no idea where that error
message is coming from. If I use openssh-server instead of my Paramiko
server, the same actions on the client work fine.

Thanks for the help!

Sincerely,

That has a lot more information.  Please include it in the email next
time.

A *very* stupid guess:  Are you reporting back the exit status
correctly?

A *very* good guess in-fact!

I hadn't even thought of that! That is exactly what the problem was. I
return the exit code, and wham! Git is happy.

Thank you so much for the help, I've been trying to figure this one
out for several days!
