Hi.

I'm getting above error each time I'm tying to clone current 2.6 tree. Archives tell that it happens when local index is currupted, but I do not have local tree, it is a fresh clone in an empty dir.

$ git clone http://kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git Getting alternates list for http://kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git/ Getting pack list for http://kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git/ Getting index for pack 81cec7c6b26c755e466a79de8dbe1c7b827a48d6 error: non-monotonic index /usr/bin/git-clone: line 33: 2025 Segmentation fault git-http-fetch -v -a -w "$tname" "$name" "$1/"

$ git --version git version 1.4.4.4

Fresh 32bit Debian testing.

It worked before (at least several months ago) and works with 1.5.2.5.

The repository you are cloning uses pack idx version #2; 1.4.4.4 predates it by a wide margin.

By the way, Debian folks are very aware of the issue and already has a backported material to cut a 1.4.4.5, but I do not know what the release schedule for their update is.

Is it an option for you to update to a more modern version from say backports.org? Everybody using git for anything serious should be using 1.5.3 or newer these days.

It is very development test machine, there is no need to use git at all, it is just a convenient way to get a needed version via 'git clone; git reset'.

I posted it so it would be stored in archive, that old enough git version does not work with recent trees, so one should upgrade if this error occures.

You should have said "better redundant than never", though ;-)

Indeed, although there were no mention that error occurs with clone, so I would find it :)

Are you sure?  http://packages.debian.org/testing/git-core says

	Package: git-core (1:1.5.6.2-1)

Your sounds more like the Debian stable version.

It is that version indeed:
apt-cache show git-core
...
 Version: 1:1.5.6.2-1
...

but it was imported there quite recently, so 'apt-get upgrade' will not catch up with major version change. 1.5 works ok, I pointed to this issue, so that resolution for the problem (i.e. upgrade to the more recent version) could be found in archive.
