Judging by your last two mails, I think you're wishing for a set of
features that neither CVS nor SVN possess. The only thing that these
two version control systems do "automatically" is detect changes to
versioned files. That's it. If you want these systems to notice *any*
other type of change -- adds, deletes, copies, moves -- then you need to
do it explicitly through the system. In other words, you run 'svn mv',
not 'mv'. The same goes for 'svn add', 'svn rm', and 'svn cp'.
Neither CVS nor SVN was designed to be perfectly "transparent" to the
user. I personally think that you'll end up driving yourself to
insanity trying to write scripts that "guess" what sorts of
adds/deletes/copies/moves your users might have intended or not. It's a
hard problem. Just bite the bullet and teach them to use the version
control system. It's not rocket science, especially not if you have a
GUI. If you want *truly* transparent versioning, then use WebDAV with
the mod_dav_svn Autoversioning feature, documented in the WebDAV
appendix of the book.
If you insist on writing scripts that try to guess what the user did,
here's the strategy I would use:
* run 'svn status': unversioned files show up as '?'. Parse those
out of the output and 'svn add' them before committing. Deleted files
show up with '!', meaning that they're MIA. Parse those out of the
output and 'svn rm' them before committing.
* implement a hash-based algorithm that tries to find correlations
between missing files and unversioned files. If you get match, then
'svn mv'.
Still, I think that down this route lies madness. SVN isn't about to
grow this feature. It's not a transparent system, nor does it ever plan
to be.
