Hi,

it seems that "cg-clone" does not fetch all tags any more - only the most recent ones (modiufied in the last N days?) seem to be fetched? [Eventually the "N days" might correspond to "changing tools to version X", but I have no way to find out.]

This happens only when using HTTP; using ssh or rsync works fine. Also, if we follow the "cg-clone" by a "git-fetch -t" command, this will load the missing tags.

Is this intentional, or am I doing anything wrong?

[For testing, try "cg-clone http://www.denx.de/git/u-boot.git"]

Best regards,

Wolfgang Denk

practice, however, there is.

  you need to run git-update-server-info every time you add or update a
tag (or best every time you push). See the NOTES section of
cg-admin-setuprepo documentation for details on how to set it up to be
called automagically at every push.

There are two types of tags: They can point to
1. a commit object
2. a proper tag object (which in turn references the commit)

git-update-server-info seems to generate info only for case 2, and so are the only ones that http can fetch.

And git-cvsimport (at least older versions of it) imports CVS tags only as type 1 ?

That would perfectly explain the situation. How can this be fixed?

Something like this tells you which one points to a commit or a tag:

for i in `find .git/refs/tags -type f`; do
  echo -n "$i "; git-cat-file -t $(cat $i);
done

Then for each commit-type $tag you do

git-tag -m ' ' $tag-new $tag mv .git/refs/tags/$tag-new .git/refs/tags/$tag

(git-tag does not accept an empty tag message - if you dislike the single-blank-message, you have to manufacture your tags with git-mktag manually.)

I suspect there is no need to manufacture the tag. Something like this should do.

*WARNING* Since I do not do Porcelain, and I am not a Cogito user, this is obviously untested. In addition, I am seriously drunk right now...

Great! Thanks a lot.

Good enough. This one actually works:

I do this. Also, this does not seem to explain why I can only see recent tags, but not old ones?

Actually I don't use push, but "cg-update" on the receiving end. Is this a problem?
