I thought I had imagined this last time, but now that it has happened twice, I'm not so sure what is going on. First pull attempt garners an unexpected EOF message; immediately pull again seems to work.

Some state:

jdl@ubuntu:/usr/src/git-core$ git --version git version 0.99.9j

jdl@ubuntu:/usr/src/git-core$ cat .git/remotes/origin
URL: git://git.kernel.org/pub/scm/git/git.git/
Pull: master:origin
Pull: todo:todo
Pull: maint:maint
Pull: pu:pu
And the error capture:
jdl@ubuntu:/usr/src/git-core$ git pull origin
fatal: unexpected EOF
Fetch failure: git://git.kernel.org/pub/scm/git/git.git/
jdl@ubuntu:/usr/src/git-core$ git pull origin

Already up-to-date.

I noticed this myself this morning. It happened twice, then after leaving it for a minute or two, it worked. Possibly traffic problems to kernel.org?

I should also report that if a spurious lockfile exists (under cygwin at least), git just dies with the cryptic "unable to create new cachefile".

The public kernel.org machines are actually _two_ different machines, and have two different addresses:

	Non-authoritative answer:
	git.kernel.org  canonical name = zeus-pub.kernel.org.
	Name:   zeus-pub.kernel.org
	Address: 204.152.191.5
	Name:   zeus-pub.kernel.org
	Address: 204.152.191.37

so with a round-robin kind of DNS resolution, you'd get alternate machines. Maybe one of them isn't up-to-date due to mirroring problems?

You can test by using the IP addresses explicitly, of course.

In particular, if the directory doesn't exist at all, or if the directory doesn't have the "git-daemon-export-ok" flag, the git daemon on the other end will just close the connection and refuse to talk to you (I thought that was preferable to give any indication of why it fails: from a security standpoint, you do _not_ want to be able to test if a random directory exists by looking at the return value of git-daemon).
