Hi,
I don't know a lot about git - I use it as a tool behind
http://cyber-dojo.com
which is an online coding dojo server.
I have a quick question...
If I do a
   git commit ....
in one thread and a
   git tag | sort -g
in another thread is the output of the git tag guaranteed to be atomic?

Can a "git commit" add or remove tags? AFAIK it can't and so the two
commands don't conflict in any way.

Sorry, I failed to ask the question I really wanted to ask...

I mean in one thread
   git tag -m 'AAA' BBB HEAD
and in another thread
   git tag | sort -g

and the question is whether the output of the git tag|sort -g command
is guaranteed to be from before the git tag -m... or from after the
git tag -m... but not "interleaved" in any way....

Cheers
Jon
