Git fetch/pull/clone hangs on receiving objects

Viewed 45982

When fetching or pulling from git repositories, or cloning a repository, I get to this point:

remote: Counting objects: 6666, done.
remote: Compressing objects: 100% (5941/5941), done.
Receiving objects:  23% (1534/6460), 11.68 MiB | 23 KiB/s  

And it hangs. The 23%/number of objects isn't a given, it ranges from single digits to up to the 60s, it seems. Also the speed for download listed freezes -- it's not like it slowly crawls down towards zero.

The guy I sit next to has no issues, so it's not a router problem. We use beanstalk for our work repositories, but I have the issue from beanstalk and github (although occaisonally it seems a github one will finish).

The problem has only seemed to crop up since upgrading to Mountain Lion and updating Xcode. I've wiped git (including XCode's) and tried installing it with homebrew. That didn't work, so I removed it and tried with their provided Mac installation package which also didn't fix the issue.

Beanstalk provides SSH urls for the git repository, but I've had no issues with connecting via SCP or SSH to servers that I've done work on.

This is killing my workflow so any help would be much appreciated!

On Mac, git fetch should be more resistant to this kind of issue, with Git 2.22 (Q2 2019): On platforms where "git fetch" is killed with SIGPIPE (e.g. OSX), the upload-pack that runs on the other end that hangs up after detecting an error could cause "git fetch" to die with a signal, which led to a flakey test.
"git fetch" now ignores SIGPIPE during the network portion of its operation (this is not a problem as we check the return status from our write(2)s).

See commit 1435889 (03 Mar 2019), and commit 37c8001 (05 Mar 2019) by Jeff King (peff).

fetch: ignore SIGPIPE during network operation

The default SIGPIPE behavior can be useful for a command that generates a lot of output: if the receiver of our output goes away, we'll be notified asynchronously to stop generating it (typically by killing the program).

But for a command like fetch, which is primarily concerned with receiving data and writing it to disk, an unexpected SIGPIPE can be awkward. We're already checking the return value of all of our write() calls, and dying due to the signal takes away our chance to gracefully handle the error.

On Linux, we wouldn't generally see SIGPIPE at all during fetch. If the other side of the network connection hangs up, we'll see ECONNRESET.
But on OS X, we get a SIGPIPE, and the process is killed.

Let's ignore SIGPIPE during the network portion of the fetch, which will cause our write() to return EPIPE, giving us consistent behavior across platforms.

Resetting the git credentials worked for me.

git config --global credential.helper store
