And I did note that it was probably a SVN issue.
(I have cc'd the subversion list now, because I hit on
something that might, or might not, help the situation.
Followups, if any should probably go there exclusively.)
However, just to make things clear, I'm not complaining.
I was merely noting that I too had seen the behavior, and
how I resolved the problem.
I certainly would not have been at all surprised to see
an error if someone had added a second file differing
case... I'm all too aware of the deficencies of the
I will note, that, though it might be difficult
(I don't know, and won't guess, how difficult in SVN),
it is definitely possible to have a rename operation
where only the case of a file name changes work on a
case insensitive filesystem.
SVN would have to not assuming that the source and target
of a rename operation can exist simultaneously.
(Mind you this isn't a bug in SVN, just a limatation
that affects portability.)
Now that I've thought about it, it probably requires that
SVN understand renames as renames (a roadmap feature),
and the current assumption actually comes because
renames aren't renames, but rather copy / deletes.
Better behavior _might_ be obtained by reversing the
operation in SVN, if that is possible: delete the old
file first, and then copy it from the revision where
it previously existed. (I believe this is how I dealt
with rename operations when I was working on a source
I can't say for sure, but this might result
in the update removing the old file first,
which would solve the problem.
