how to fix the broken tagging system?

[Ronny Pfannschmidt]

Hi,

the last few weeks the way how tagging works in hg was very frustrating.

There are various issues with it being a versioned file instead of
proper meta-data.

1. Tags don't propagate with the tagged revision.

It's really not fun to push a tag just to see its not there in the
remote repository.

2. Tags can change without further notice

Its really no fun to pull in changes, and get existing tags changed that
way - no pull op should be able to alter tags without asking me first.

So it kills a lot of trust.
To be sure i have to double check tag-changes, 
i shouldn't have to do that.

3. simple schemes for trying to transfer tags with their revision just
don't work

rev+1 cant work, as tags can be added much later (for example the svn
converter adds them after converting the complete history)

4. git, bzr, monotone - all do it right, just hg is plain wrong (and
thus is a pain)



As far as i can tell the only good solution to fix it is a proper system
for managing meta-data about revisions.

BTW, signatures have pretty much the same issues.
