And then you cannot really say "the user explicitely asked > to have that signed tag rewritten". That sounds like saying that specifying "HEAD" as the revision (_and_ using --tag-name-filter) is not explicitly asking for tags to be rewritten. ? Aside from that, wouldn't the signed tag currently be rewritten? With current git, if I have a signed tag named "my_signed_release", and I can verify its authenticity using 'git tag -v my_signed_release', and then I run filter-branch with '--tag-name-filter cat', my previously signed tag is replaced with a light weight tag and of course 'git tag -v my_signed_release' fails. I don't see how the situation for signed tags changes much. The current state is that the signature cannot be preserved, so if "new" signed tags are desired, they must be handled specially. On the other hand, the situation for unsigned tags becomes much easier, assuming you want to retain the tag properties. Aren't unsigned tags more common than signed ones? So right now, tags matching the refspec are rewritten. They are currently rewritten with a lightweight tag. I don't think you have explained what is wrong with defaulting to creating a new tag object which retains as much information from the original tag object as possible. In other words, why would a user _not_ expect that the tag filter would preserve the tag message? Can you describe some scenario where a user would use --tag-name-filter and would prefer the creation of new light-weight tags over tag objects? I can't imagine one in my own situation. Maybe there is some example in your own workflow? -brandon -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
