[PATCH/RFC 0/5] libify verify_tag()

[Jonathan Nieder <jrnieder@gmail.com>]

Hi,

I noticed that ‘git tag -v’ runs git-verify-tag (dashed form), and while
fixing that, I thought, why not make cmd_tag() run verify_tag()
directly?  Here is what that would look like.

The performance impact is pretty negligible: t/t7004-tag.sh is about
2% faster after the change here (with hot or cold cache, it doesn’t
matter).

What do you think?
Jonathan Nieder (5):
  tag: Run ‘git verify-tag’ using its undashed name
  verify-tag: use sigchain library to block SIGPIPE
  Expose verify_tag()
  tag: Do not spawn a separate process for verify-tag
  verify_tag_signature(): let caller look up tag object sha1
