Re: Export entire changed files for zip patch

I was suggesting to 'lug around the whole revision' as i dont see that as a
large issue.
i tarred up nearly 200,000 lines of php source this morning and its only
about 15 MB using
gzip compression.
On the sdlc thing, i was suggesting that creating tags and 'lugging them
around' is the svn way
but thats based on my somewhat moderate experience w/ svn thus far. from my
perspective just
tagging a revision and pushing it out to the servers is the most
straightforward approach.
and you can definitely push that over ftp.
the only reason i can see for pushing out the differences and patching the
source is if you have slim
transfer requirements to the servers themselves or a ton of source to push;
which maybe you do, i
dont know.
patching live code against differences is cool and all, but i thought you
were looking for something simple.
