* tdb: fix short write logic in tdb_new_databaseRusty Russell2010-08-161-1/+15
| | | | | | | | | | | | | | Commit 207a213c/24fed55d purported to fix the problem of signals during tdb_new_database (which could cause a spurious short write, hence a failure). However, the code is wrong: newdb+written is not correct. Fix this by introducing a general tdb_write_all() and using it here and in the tracing code.

* tdb: use tdb_nest_lock() for seqnum lock.Rusty Russell2010-04-221-3/+3
| | | | | | | | | | | This is pure overhead, but it centralizes the locking. Realloc (esp. as most implementations are lazy) is fast compared to the fnctl anyway.

* tdb: cleanup: rename global_lock to allrecord_lock.Rusty Russell2010-04-221-1/+1
| | | | | | | | | | | | | The word global is overloaded in tdb. The global_lock inside struct tdb_context is used to indicate we hold a lock across all the chains. Rename it to allrecord_lock.

* tdb: cleanup: split brlock and brunlock methods.Rusty Russell2010-04-221-2/+3
| | | | | | | | | | | | | | | | | | | | | This is taken from the CCAN code base: rather than using tdb_brlock for locking and unlocking, we split it into brlock and brunlock functions. For extra debugging information, brunlock says what kind of lock it is unlocking (even though fnctl locks don't need this). This requires an extra argument to tdb_transaction_unlock() so we know whether the lock was upgraded to a write lock or not. We also use a "flags" argument tdb_brlock: 1) TDB_LOCK_NOWAIT replaces lck_type = F_SETLK (vs F_SETLKW). 2) TDB_LOCK_MARK_ONLY replaces setting TDB_MARK_LOCK bit in ltype. 3) TDB_LOCK_PROBE replaces the "probe" argument.

* tdb: add TDB_DISALLOW_NESTING and make TDB_ALLOW_NESTING the default behaviorStefan Metzmacher2009-12-161-0/+30
| | | | | | | | | | | | | | | We need to keep TDB_ALLOW_NESTING as default behavior, so that existing code continues to work. However we may change the default together with a major version number change in future. metze (cherry picked from samba commit 3b9f19ed919fef2e88b2f92ae541e07bc7379cd1) Signed-off-by: Stefan Metzmacher <metze@samba.org> (This used to be ctdb commit c1c0ede32dc00ed619d1cf5fda40a9de43995f3a)

* Attempt to fix bug 5684Volker Lendecke2009-12-161-1/+1
| | | | | | | | | | | | | | | | | | | | With the ctdb checkin dde9f3f006 tdb optimized out write lock checks for write-enabled transaction. Sadly, this also removed the possibility to ever remove dead records left over from tdb_delete calls within a transaction. Tridge, please check this! Did dde9f3f006 have any reason beyond performance optimizations?

* lib/tdb: wean off TDB_ERRCODE.Rusty Russell2009-12-161-3/+6
| | | | | | | | | | | | | | | It was a regrettable hack which I used to reduce line count in tdb; in fact it caused confusion as can be seen in this patch. In particular, ecode now needs to be set before TDB_LOG anyway, and having it exposed in the header is useless (the struct tdb_context isn't defined, so it's doubly useless). Also, we should never set errno, as io.c was doing.

* lib/tdb: TDB_TRACE support (for developers)Rusty Russell2009-12-161-23/+209
| | | | | | | | | | | | | | | | | | When TDB_TRACE is defined (in tdb_private.h), verbose tracing of tdb operations is enabled. This can be replayed using "replay_trace" from http://ccan.ozlabs.org/info/tdb. The majority of this patch comes from moving internal functions to _<funcname> to avoid double-tracing. There should be no additional overhead for the normal (!TDB_TRACE) case. Note that the verbose traces compress really well with rzip.
