* | do not use a ctdb_record_handle for client fetch_lock/store_unlock any moreRonnie sahlberg2007-04-174-63/+37
| | | | | | | | | | | | | | | | | | | | change ctdb_client_fetch_lock to return a status code instead of a record handle and make it unconditionally fill in data. change ctdb_client_store_unlock to take ctdb_db and key as arguments instead of a record handle update the ctdb_fetch.c test to use the clientside helpers for fetching and storing data (This used to be ctdb commit 22d5d40375e0135916c97945646f94119612615d)

| | | | | | | | | | | | | | this will be the core of the non-blocking lock idea for ctdb, it will be used in place of ctdb_ltdb_fetch(), but will also get a lock. It re-starts a request if it needs to block (This used to be ctdb commit afa479026cf6293e6a878c8a329cdac035284672)

* | this is a demonstration of an idea for handling locks in ctdb.Andrew Tridgell2007-04-165-2/+258
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | - when we do a store_unlock the lock record becomes unlocked, so we must destroy it (or we leak memory) (This used to be ctdb commit d85955640e670dd580073da96b25fb8a10c08d18)
