[BUG] git clone -q ends with early EOF

[BUG] git clone -q ends with early EOF

[Marek Vasut]

Hello,

I am trying to clone a repository and I am getting the following output:

$ git clone -q git://kernel.ubuntu.com/ubuntu/linux.git
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed

The "fatal:" lines usually appear a few minutes after running the clone. Of 
course, the clone does not finish successfully. Interestingly, when I drop the 
'-q' option from the git clone commandline, the clone finishes correctly.

My git version is:

$ git --version
git version 1.8.4.rc3

Is this a known issue?

Thank you!

Best regards,
Marek Vasut

This sounds suspiciously like 05e95155 (upload-pack: send keepalive
packets during pack computation, 2013-09-08) that is cooking in
'next'.

If you are talking with other people's server side, you are SOL
until the server end gets the patch.

As Junio mentioned, this does seem like the issue that 05e9515
(upload-pack: send keepalive packets during pack computation,
2013-09-08) tries to fix. The server is quiet for a long period while
preparing the pack, and something in the network stack thinks the
connection has timed out and kills it.

One way you can check this is by running:

  time git clone -q git://kernel.ubuntu.com/ubuntu/linux.git

If it's a network timeout, it will die consistently at some nice round
number. In this case, I just ran that command twice, and it died both
times at just a hair over 2 minutes.  So that is probably what is going
on.  There's no proxy on my end, so presumably there is some front-end
reverse proxying happening on the server end, and it has a 2-minute
timeout.

The keepalive patch is not in any released version yet, but we have been
running it in production at GitHub for a few weeks. You may want to file
a support request with the Ubuntu folks asking to pick up the patch, or
to increase the timeouts on their proxies.

That is good to hear; I'd feel safer to bump the scheduled
graduation date to 'master' for the topic in that case.

Like tomorrow ;-)

Thanks for explaining guys, I will try to poke the canonical guys with reference 
to this thread.

I reported the issue on Ubuntu Lunchpad here [1], so I hope they will eventually 
fix it.
