A few weeks ago upgrading from 1.3.x to 1.4.1 I had a problem with
git-daemon. I started git-daemon on a terminal but did not redirect
stdin/stdout/stderr to /dev/null (actually using daemon(8) on freebsd
without -f but just disowning the process and closing the terminal
works fine too, nothing freebsd/daemon(8) specific). After closing
the terminal I was not able to use the git-daemon anymore with some
versions of the git. So now I took some time and tried to find what
was the reason for that.
It seems to be related to the client version too (git without version
appendix is the current next (028cfcba78c3e4).
583b7ea31b7c16~1 (last good):
$ git clone git://host:9419/foo
$ git1.3.2 clone git://host:9419/foo.git
(cloned successfully, both no output)
583b7ea31b7c16 (first bad):
$ git clone git://host:9420/foo

(/somewhere is the cwd on the client)
I tried to find which part of the patch caused the problem and came
out with the patch below. With this I can clone with git1.3.2 again
but then git 1.4.x does not show any statistics about packing, its
just a starting point to look at. Perhaps someone has an idea why
this happens. I've got to sleep now :)
