I just tested git-1.7.6-1.fc15 and the --quiet option works fine there.

Do you really need this fixed in F14 or F15 and later is enough.

Really?  I tested git-1.7.6-1 on f15 and found that it prints the "Unpacking objects" just as Jesse reported.  I looked for a while at the code the other day and could not come up with a fix.  (At least for me, it's not trivial to follow the way things work in the push process.)

[tmz@f15-64 git-test]$ mkdir /tmp/git-push-bug && cd /tmp/git-push-bug
[tmz@f15-64 git-push-bug]$ git init --bare test.git
Initialized empty Git repository in /tmp/git-push-bug/test.git/
[tmz@f15-64 git-push-bug]$ git clone test.git
...
[tmz@f15-64 git-push-bug]$ cd test
[tmz@f15-64 test]$ touch foo; git add foo; git commit -m testing
...
[tmz@f15-64 test]$ git push --quiet origin master 
Unpacking objects: 100% (3/3), done.

Running with GIT_TRACE=1, you can see a little more, but to really follow it, requires deeper debugging (I'm from the school of "add some printf's to follow the code" when it comes to C.)

[tmz@f15-64 test]$ rm -rf ../test.git && git init --bare ../test.git

You can see that the -q option is not being passed to unpack-objects as it is to pack-objects and other subcommands.  I was not able to determine where this was missing in the git code.  Might be worth asking on the git list, as someone there may well know offhand.

I tested git push when I pushed tigervnc changes earlier today so I might have pushed merged branch accidentally (i.e. git merge && git push --quiet) and this codepath is probably OK... Sorry for false information.

I did some scratch builds with the patch that Clemens Buchacher so kindly sent to the git list¹.

F15: http://koji.fedoraproject.org/koji/taskinfo?taskID=3240115
F16: http://koji.fedoraproject.org/koji/taskinfo?taskID=3240103

This fixes the issue for me, but it wouldn't hurt to have more testing to make sure it doesn't have any adverse side-effects.

Unfortunately, the fix had an unseen regression.  When push --quiet was used and the remote end was an older version, the remote end hung up.  This change was released upstream in 1.7.6.1 and reverted in 1.7.6.2.  I've pushed 1.7.6.2 into testing.  We'll have to revisit this when a more compatible fix makes it upstream.

This is discussed in more detail on the git list:
