Re: Export entire changed files for zip patch

just guessing a bit; as i havent used this myself; but isnt this what
patch<http://en.wikipedia.org/wiki/Patch_%28Unix%29>is for?
basically the flow here is to diff the to repositories; dump the diff of
each file in the repo to a diff file.
then recursively apply the diff files to the target source base using patch.
you would still need to handle adding new files and removing deleted files

in order to get a listing of the files that have changed between 2
components of the repository (typically a development branch and the trunk)
svn diff -x -w svn+ssh://user@repohost/trunk svn+ssh://user@localhost/branch-wc
| grep '+++'
svn diff -x -w svn+ssh://suer@repohost/trunk svn+ssh://user@localhost/branch-wc
| grep '\-\-\-'

so, in my mind i would start out by using those commands to generate a list
of files then iterate over the list producing the diff files.
note here, im assuming the diff output from svn is compatible w/ gnu diff
(because thats what patch takes as input).

you will have to have some client-side script to handle the merging; no
matter what the implementation, so
if you are deploying the php to windows and unix(ish) machines you will
likely have to maintain separate scripts for both platforms.

why not just use a tagging approach and push out revisions of the source? i
think this would be a more direct solution and very easy to implement.
also, i think tagging is more in tune w/ the svn way of facilitating sdlc
