Hey, I've noticed that the links in the TOC at the top of the various
online docs is broken. They all refer to index.php that doesn't seem
to be there. Is there supposed to be a sym link or something?

The original implementation where state actions were declared

the standard C model better - it's hard to auto-generate that stuff in

Hey, the client core prints a date at the point in the log file where it
starts. On my system the month is off by one. Is this unusual?

I'm kind of stuck on the branch. ALL of the lib tests seem to work,
but when I try to mount via the kmod, mount returns mount: Not a
directory
As far as I can tell from the logs everything
of this looks OK to me - the only things I noticed at all were that
fs_add_sm: parent_cleanup returned 1 and the downcall write returned 1.
I can't determine if either of those indicate an error.

did we like/dislike about them?

I guess you have always had that in the path so it hasn't affected you.

find any more. I'll get it all checked in for the next nightly.

Rob,
there is a bug in test/client/vfs/test-mkdir at line 230. After making

want to be sure.
Comments appreciated.

There is a function in src/server/pvfs2-server.c:
server_purge_unexpected_recv_machines(void)
is that a new function? and under what circumstances is it used?

to field unexpected messages in preparation for the server to exit.
So no more new messages will be received after the server gets a signal to
terminate gracefully.

has anyone run the server with valgrind?
I have a nasty memory bug and I'm trying to use it to find the problem,
but the server won't run with it - tells me some of the db functions
don't work
Any experience?

Ignore this - I upgraded valgrind and it went away.
Now if I can just figure out what all this valgrind output means :-(

cleanest, most logical means.

OK, guys, I have another issue I want input on. When child SMs
terminate they have to notify their parent. The parent has to wait
for all the children to terminate. So I've been thinking to use the
job subsystem for this: the parent would
think I'll use the
minmal method. The only real diff is Sam's preference not to use a
counter. We can go around on that, but I'm leaning towards a counter,
at least for the initial implementation.
