53_ctdb_transaction.sh, 61_ctdb_persistent_safe.sh,
62_ctdb_persistent_unsafe.sh). Remove "_simple" from some test
filenames in the simple subdirectory - that's redundant. Always run
ctdb as $CTDB to allow $VALGRIND magic to be used. Use pgrep/pkill to
detect/kill local daemons so those running under valgrind can be found
too - to support this, always run local daemons with the full path to
the executable. run_tests now supports -s option to print sumamry
when done - with more and more tests, it is getting hard to follow
progress. Sort the output of commands in 06_ctdb_getpid.sh to make
sure they compare nicely and also allow the processes' executables to
be called "memcheck" to catch those running under valgrind. Remove
redundant calls to onnode in commands run from calls
try_command_on_node in some tests. 41_ctdb_ban.sh and
42_ctdb_unban.sh avoid banning the recmaster, since this causes the
recmaster to be reassigned and all nodes to be unbanned. Minor

- fixed memory leaks in the 3 packet receive routines. The problem was
that the ctdb_call logic would occasionally complete and free a
incoming packet, which would then be freed again in the packet
receive routine. The solution is to make the packet a child of a
temporary context in the receive routine then free that temporary
context. That allows other routines to keep or free the packet if
they want to, while allowing us to safely free it (via a free of the
temporary context) in the receive function

(This used to be ctdb commit 22d5d40375e0135916c97945646f94119612615d)
The problem we have is this:
- we want the client smbd processes to be able to 'shortcut' access
to the ltdb, by directly accessing the ltdb, and if the header of
the record shows we are the dmaster then process immediately, with
no overhead of talking across the unix domain socket
- a client doing a shortcut will use tdb_chainlock() to lock the
record while processing
- we want the main ctdb daemon to be able to set locks on the
record, and when those locks collide with a 'shortcut' fcntl lock,
we want the ctdb daemon to keep processing other operations
- we don't want to have to send a message from a smbd client to the
ctdbd each time it releases a lock
The solution is shown in this example. Note that the expensive fork()
and blocking lock is only paid in case of contention, so in the median
case I think this is zero cost.
(This used to be ctdb commit a3248c3e2b740cd2403acffd3c1f6a33dca0ea03)
