git fetch hangs over ssh

[wangs...@gmail.com]

hi,

I've recently installed latest version of git extensions and that came with latest version of msysgit.

The issue is when doing a git fetch over ssh. The command seems to hang.

I've tried to do git fetch --verbose and the output indicates that it goes through all the branches and grabs the latest changes.

After completing the last one, however, it just hangs there.

I know it is the last one as I have another linux machine that i'm able to compare it against.

I thought it might be incompatible git versions between my local and the remote so I also tried downgrading msysgit to previous version. same issue.

Does anyone have any idea what the issue is or how i can further troubleshoot this?

thanks

There are some long standing issues with some of the push/pull interfaces that appear to be related to subtle differences between the linux and windows networking, and the creation of the 64k side band.

 

I'm guessing that a proper fix will require that the Linux 'optimisations' will need to be 'undone' such that the windows equivalent doesn't have whatever race condition causes the lock (that is, various folks find a "pause 1" in various places works for them, but isn't a global fix)

 

The problem neeeds more eyes and ideas.

 

Here are all the links I'd collated, but haven't had any time to investigate further.

also check it's child commits for comments. As well as the Msysgit fixes (which I haven't fully researched).

Issue #457 is purely about push via native git protocol.

Thanks Philip. That was a very comprehensive answer. 

I'll see if anything here works for me.
