Garrett:
Subversion's architecture shoots itself in the foot here. Because there is
no difference between a "branch" and a "tag", I can rewrite your sentence
like this:
"well, as i said on IRC earlier, i can't come up with a use case that would
involve diffing two different _tags_ and applying the results to a third."
Well, I sure can :).
I branch the main line of Optasia away from the code that Jake and Tony are
working on so I can get ATI Radeon 8500 support in without destroying what
they are doing. I branch from an existing tag. I figure to do this I'm
doing:
svn cp http://svn.ninetjer.org/svn/optasia/tags/optasia-gdc_2001
http://svn.ninetjer.org/svn/optasia/branches/optasia-radeon_8500
(please god all mighty don't tell me I need to check out either repository
to do this...)
OK, so now Jake is working on the next major milestone (the E3 game demo).
Let's say he finishes that (dedicated worker he is), but I've been spending
so much time fighting with our old CVS repository that I'm _still_ working
on Radeon support. So, I want to do the following merge to get the new
updates to my working copy:
svn merge http://svn.ninetjer.org/svn/optasia/tags/optasia-gdc_2001
http://svn.ninetjer.org/svn/optasia/tags/optasia-e3_2001
I figure merging diffs between two tags will be the 99% case, diffing
between arbitrary revisions sounds like something only a developer who is
really pissed off is going to do (as in my description of that scenario a
week or two ago).
Sincerely,
Jay Freeman (saurik)
