OK, I've spent another day battling with my broken repository.
For some reason I can dump incremental some incremental revisions but
not others. The error messages I get seem to chosen randomly from
"Unexpected end of svndiff input"
When I try to commit I get an "svn: Unexpected end of svndiff input"
error
My only explanation at this point is that somewhere along the line I
had to restore from a subtly corrupted .dump file, and the problem just
took about fifty committs to surface. While I was working through
problems with file permissions I had to dump and reload the database a
few times.
Without words of advice or encouragement, I'll probably just throw out
our entire history, start with a fresh repository, and import my latest
working copy. I don't think I have enough gumption left to keep
battling with this broken repository or to merge by hand all of the
changes since my last backup.
Thanks,
Drew
