It seems to me that the refactorings and support for shelving/checkpointing
being developed right now are putting into place a good foundation for
implementing pull request type functionality as well. I like that merges in
Subversion are always done in a working copy, not directly on the server.
This allows to apply a PR, test, make changes, etc. The workflow for a PR
as I see it is to produce something akin to a patch file which contains the
changes and other information needed to merge, e.g. the revision the PR is
based on. Furthermore I think there should be a place in this file for
"description" or log message so that users could easily identify what the
PR is. Also that could be copied into the log message for the commit. This
PR could be sent by email or through any other means such as a bug tracker
attachment. If a future non-versioned server-side storage is implemented
then that could be utilized. But bottom line I think this depends directly
on the same logic needed for checkpointing.
