Fwd: Re: [git-users] Git clone fails with "bad pack header", how to get remote log

[kevin molcard]

Hi all again,
here is my second email :).
It contains the git versions in my system.
FYI, I updated git to 1.8.0 on my remote but still having the same issue.
Another thing that might be interesting is that it seems to happen only 
when cloning from Windows build machine (i.e. I send 2 clone command on 
from the mac and 2 from the Windows and it seems to always fails on the 
Windows).

Thanks again
Kevin

Hi, Kevin.
I noticed my Cc'ed messages did not reach the main Git list for some
reason (even though I did see these my messages coming from the
list-management software), and the did not show up on Gmane [1].
I do not know what's the reason is, so please try forwarding my first
reply to your original message and the message I'm replying to now
(with versions of software involved) to that list yourself -- maybe
you'll be more lucky.

Sorry for the delay.

This reminds me of a bug fixed in 1.7.12.1 [1]:

* When "git push" triggered the automatic gc on the receiving end, a
  message from "git prune" that said it was removing cruft leaked to
  the standard output, breaking the communication protocol.

In any case, bugs should be reported to the main Git list (which is
git at vger.kernel.org), not here.
I'm Cc'ing the main Git list so you'll get any responses from there, if
any.

Kevin, please answer to this message (keeping all the Ccs -- use "Reply
to group" or "Reply to all" in your MUA) and describe exactly what Git
versions on which platforms your have.

Fwd: Re: [git-users] Git clone fails with "bad pack header", how to get remote log

[kevin molcard]

Hi all,
I am forwarding a reply I got from a message I sent to git user mailing 
list because of a "bad pack header error" (more information below).
I will forward another email where I give all the git versions of my system.

Any clue on this would be much appreciated.

Thanks in advance
Kevin
