Here you go.
You can pull from the "oom" branch here:
git://git.infradead.org/users/meyering/tabled.git
I think I've addressed all of your preferences, merging
most OOM fixes into one commit, but not the two you mentioned
that should stay separate. I also left the sizeof(s) one separate.
However, I did leave the copyright year updates in.
If they're a problem, let me know and I'll do another round.
Otherwise, I can send a patch to update all of the
remaining ones to include 2010 so this won't be an
issue for 3 more months.
$ git shortlog HEAD ^origin/master
Jim Meyering (4):
server/server.c: use sizeof(s) rather than equivalent "64"
don't dereference NULL on OOM
server/status.c: don't deref NULL on failed strdup
server/bucket.c: don't deref NULL upon failed malloc
