Holy cow. Well, that's an Alpha bug, then :-).
First of all, thanks a million Philip for the intense debugging
efforts you've been putting in here.
So...
What we had was in interaction between two independent bugs: the
libsvn_wc code was (for a while) in a state where it would ignore a
lock encountered during commit -- and simultaneously, there is a bug
in ra_dav that allowed a commit to proceed against an out-of-date
file.
I'm going to work on the ra_dav bug now -- if it's what it seems to
be, it needs to be fixed before Alpha.
As for revs 2452, 2470, and 2504: I'm leaning toward reverting them
for Alpha. With this ra_dav thing to debug, there just isn't going to
be time to thoroughly review even the changes already committed or
posted, let alone to finish issue #749. And if the issue isn't going
to be finished, there's no compelling reason to have its beginnings in
the code when we release Alpha; in fact, it could even be sort of
confusing to have it in that state, if the Alpha code gets a lot of
new eyeballs as we hope.
I'll start debugging the ra_dav thing now, Ben or I will probably
revert 2452 and friends later today. Speak now or forever hold your
peace :-).
It need not be said -- but I'll say it anyway -- that this is *not* a
comment on the quality of any of those revisions, it's just an issue
of risk control and API consistency for a major release.
