Hello there,

What did you do before the bug happened? (Steps to reproduce your issue)

    git log --format='%(describe)' -n1

produces a different result than

    git describe --tags

What did you expect to happen? (Expected behavior)

I expected both to produce (roughly) the same result. At least, reference the same tag.

What happened instead? (Actual behavior)

    git log --format='%(describe)' -n1
    v0.11.0

and

    git log --format='%(describe)' -n1
    v0.3.0-beta-253-g4ccd023

What's different between what you expected and what actually happened?

git log with %(describe) placeholder does not seem to find the most recent tag as git-describe would do. Is this intended?

I tried to reproduce your issue. I have linux.git shallow repo (master branch pulls from torvalds' mainline tree and stable branches pull from stable tree). HEAD currently points to v5.15-rc5 tag.

The result (note that I use custom-compiled Git):

``` $ /opt/git/bin/git version git version 2.33.0

$ /opt/git/bin/git log -n 1 --format='%(describe)' v5.15-rc5

$ /opt/git/bin/git describe --tags v5.15-rc5 ```

Both results (git log and git describe) are same.

Yes. Good one. Absolutely correct. I wasn't able to reproduce that with Linux repository, too.

Problem is observed only in some repositories while others seem fine.

I was able to reproduce it with a freshly cloned version of:

if the repository you are looking at has non annotated tags (the ones that have no signature or message and that are created by default with `git tag`), then that is expected and explained in the documentation for the '--tags' option you are using.

Yes, that's the case in the example repo he showed. I don't think there is currently a way to convince %(describe) to use "--tags" in the underlying describe command, but it seems like a reasonable extension if somebody is interested in writing it. We already take some options to %(describe), so the syntax is prepared to add more.
