Hi guys,

I run into a weird problem when trying to update my clone of the linux-2.6 repository from Linus:

--- # cg-update -f 17:09:00 URL:http://www.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git/HEAD [41/41] -> "refs/heads/.origin-fetching" [1] Getting alternates list Getting pack list error: Unable to find 2ed5e6d09e266bd2288d49aaaf240ed8c468c13c under http://www.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git/

I use the latest available git and cogito for this and I have no idea which is at fault. Using rsync as transport it even looks more worse:

Maybe this is a problem of the kernel.org synchronization, but otherwise it should be fixed. Will there be a way to get some useful messages to the end user in case of an error or some sanity checks that the tree you are pulling from is in sane state or not?

forget about this thing. The reason for this problem was the kernel.org mirroring and the repository wasn't in a sane state. However it would be great if we can detect this somehow.

  well, we did detect this and error out. ;-) What else would you like
GIT/Cogito to do? Anything particular that could make this less
confusing?

I actually have no real idea, but the "object fetch failed" doesn't tell me anything besides that an object seems to be missing. Maybe this is a problem we have to live with when using the kernel.org mirroring.

Is this an issue with the two servers (or virtual servers?) behind the kernel.org DNS name being out of sync?

Would it make sense to configure the individual servers to be http-alternates of each other?
