1. svnversion reports the revision of the check-out, not the revision of the last
modification.
2. svnversion does not provide the $Date$ information.
3. svnversion won't report anything on 'svn export'-ed sources.
All that would be handled if there were a way to modify a transaction being committed :)

Well, if Subversion set an svn:binary to true/false just to report the heuristics, in addition to
svn:mime-type, that would've helped somewhat. But Subversion heuristics only runs on
newly added files.

No, it is also set on existing files as they're modified.

Now you tell me about that. I am still trying to weed out 1.6 clients (which break horribly by
nested 'svn mv')- since CentOS does not update the base version of the packages during
the release lifetime, CentOS 6.x is stuck with Subversion 1.6.
Thanks to WanDisco for providing the CentOS RPMs for Subversion 1.7/1.8 :)
It would be nice if there were a 'start-access' script that is run on any access to the
repository - that can be used to block such older clients from even accessing the
repository.
Speaking of 'wish' items:
- How hard would be to implement client-side hooks? I know TortoiseSVN has them, but
they're local - and to be really useful, they need to be propagated from the repository.
And it would be nice to have them supported by the default commandline client. If they
were supported, the tasks like the ones described above could be relegated to the client
side, and the server-side hooks could then just reject the commit if the client failed to run
the script.
- How hard would be to allow modifications to a transaction by pre-commit? If it is just the
issue of client-side caches going stale - can a "shadow transaction" be created that
records all the modifications by the pre-commit script and then sends it back to the client
to apply to the WC?

Alexey.
