I always thought that not having a canonical implementation
was one of the greatest weaknesses of git. Good to hear
that they finally improved on that side.

Will libgit2 be just another dependency in the build process?
As long as I don't have to update that part frequently, it's fine
with me.

Hm. Concentrating on SVN is certainly a priority. But if there
are spare cycles and everyone coding the extra parts has fun
doing it - why not?
The only issue I see is the wording in any announcement
concerning git support. However, as long as it is considered
an experiment, there will still be plenty of time to see how
well the git support progresses and when to make it an
official feature.

I think part of coding the initial git support will be finding out
how to integrate git without compromising SVN functionality
and usability. And you will never know before trying it. Under
Linux, I use RabbitVCS which does an o.k. job to support
SVN, git and hg in a (seemingly) single client.
That said, RabbitVCS doesn't support the full feature set of
any of those systems and I would like to see TSVN continue
to always support anything SVN offers and will offer.

My understanding is that TGit started off as a clone of TSVN
(which was the Right Thing To Do back then). The beauty of
GPL is that we can now use code from that project when we
feel like it.
Somebody else already raised the point of not adding tons of
"if (is_git) do_x(); else do_y()" code. The TSVN current code
is very tightly linked to the UI, i.e. there is often no separate
logic layer. That's been fine for TSVN's scope and complexity
in the past but also limits portability, tool integration or using
$fancyUiLibDuJour.
If the only thing that adding git support achieves is cleaner
code in general, I'd say it is worth it.

I say: Give it a try! There is no reason why even experimenting
with it should be a problem. Maybe, open a branch for that
to reduce the impact on the upcoming 1.8 release.
Please respond with your thoughs....

Took me a while to formulate a coherent position. And I feel
a bit guilty of having TSVN left aside for the last year or so.
But I think that server scalability and performance are absolutely
crucial in a commercial environment. And this is what keeps
SVN relevant and ultimately pays my bills.
On a lighter note: Off to the beach now ...
