Hi

Using HTTP as transport, I've noticed that after using git-gc on a git server, I can't push to that repo anymore: "No refs in common and none specified." Client and server are both 1.6.2. Is ths a bug or do I have to do something after executing git-gc on the server?

Thanks! Steve

Check the permissions of the files on the server, I once accidentally executed git commands as root user and the HTTP server was later unable to read/write the repository properly.

The perms are okay, yet the error message remains.

I had this happen once after having upgraded git on the server in question and then running "git gc" against a repo. I didn't remove the old (not packed-refs knowing) git though, and when I later tried to push to it, it couldn't find any refs since the old receive-pack was being used, and it didn't know about packed refs.

Worth checking, possibly.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.

Which file/contents do I have to look for or remove in order to kick the old not packed refs?

could you try running git update-server-info?

Actually, you have to undo the ref-packing performed by gc. You can do it this way (quick and dirty):

	$ git show-ref |
	  while read sha1 name
	  do
		mkdir -p .git/$(dirname $name) &&
		echo $sha1 > .git/$name
	  done

Re: git-push on packed refs via HTTP

Hi Dscho

Thanks for your snippet, that did the trick. I only had to alter it slightly because the repo on the server is bare:

git show-ref |
while read sha1 name
do
  mkdir -p $(dirname $name) &&
  echo $sha1 > $name
done

Just for understanding: Why is this step necessary? Does it have anything to do with serving the repo over HTTP at all?

Cheers, Steve
