Well, Ben didn't quite backtrack; there are just different sequences
of steps possible. Some of them, the client will protect against;
others it won't, as we have now learned, hence Blair filed bug #2309.
I was just talking this over with Ben, and he had a very nice way to
put it: "In comparison with CVS, the safety has gone up, but the
useability has gone down."
SVN is safer, in the sense that it will not munge your binary files
unless you explicitly tell it to.
Unfortunately, the effect of this "safety" is to tempt people into
marking huge swaths of their trees with properties that imply that
stuff is text -- either by mime-type or by keyword expansion. That's
what happened to you. You wanted keywords expanded 95% of the time.
You set it to happen on everything (assuming, fairly I admit, that
you'd be protected against binary files getting keyword expansion).
Then when SVN did exactly what you said, instead of what you wanted &
expected, you had a problem.
By the way, I'm not denying that your expectations were reasonable.
Once bug #2309 is fixed, life will be easier.
In the meantime, the workaround is to find all files with
svn:mime-type of "application/octet-stream", unset any svn:keywords
properties on them, and fix them if they're corrupted. Sorry, I know
that's not ideal, but it's what can be done right now.
