Inspection of the origin git log shows that the change was never propagated upstream.

[Jelmer Vernooij (jelmer)]

This is a bit odd, it seems like git is sending a pack that contains deltas against texts that the server doesn't know about.

[Jelmer Vernooij (jelmer)]

Roland fixed this.

[Matt Giuca (mgiuca)]

I seem to have this bug, in 0.5.2 of bzr-git. Wasn't this marked fix released in 0.4.2?

It's exactly the same as described, except I don't see a Python traceback when I Ctrl+C git (not sure why I would) or bzr. It just hangs forever.

Note that I am using $ bzr serve --git --allow-writes on the server (localhost), and $ git push git://localhost/ on the client (same machine).

[Matt Giuca (mgiuca)]

I have just updated to the trunk versions of bzr-git (trunk r1056) and dulwich (trunk r705), and I am still getting this problem. I am still unable to see a traceback also. I think it should be marked not fixed, unless I am getting a different bug with the same symptoms?

Which commit was Roland's fix? I am guessing (from the date stamps) maybe 598.2.2.

Here is a full log of what I'm doing.

1. Create a new bzr branch with a commit.
2. Use bzr serve --git, and then pull it to git with git://localhost/, which works well.
3. Commit a change using git.

Then, in one window:

bzrbranch$ bzr serve --git

In the other:

gitrepo$ git push git://localhost/
localhost[0: ::1]: errno=Connection refused

This seems to've regressed.
