2010-02-17tdb: use tdb_nest_lock() for seqnum lock.Rusty Russell1-3/+3
This is pure overhead, but it centralizes the locking. Realloc (esp. as most implementations are lazy) is fast compared to the fnctl anyway. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: use tdb_nest_lock() for active lock.Rusty Russell2-5/+18
Use our newly-generic nested lock tracking for the active lock. Note that the tdb_have_extra_locks() and tdb_release_extra_locks() functions have to skip over this lock now it is tracked. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-22tdb: use tdb_nest_lock() for open lock.Rusty Russell3-15/+10
This never nests, so it's overkill, but it centralizes the locking into lock.c and removes the ugly flag in the transaction code to track whether we have the lock or not. Note that we have a temporary hack so this places a real lock, despite the fact that we are in a transaction. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: use tdb_nest_lock() for transaction lock.Rusty Russell2-32/+23
Rather than a boutique lock and a separate nest count, use our newly-generic nested lock tracking for the transaction lock. Note that the tdb_have_extra_locks() and tdb_release_extra_locks() functions have to skip over this lock now it is tracked. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: cleanup: find_nestlock() helper.Rusty Russell1-28/+23
Factor out two loops which find locks; we are going to introduce a couple more so a helper makes sense. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: cleanup: tdb_release_extra_locks() helperRusty Russell3-17/+22
Move locking intelligence back into lock.c, rather than open-coding the lock release in transaction.c. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: cleanup: tdb_have_extra_locks() helperRusty Russell4-5/+17
In many places we check whether locks are held: add a helper to do this. The _tdb_lockall() case has already checked for the allrecord lock, so the extra work done by tdb_have_extra_locks() is merely redundant. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: don't suppress the transaction lock because of the allrecord lock.Rusty Russell1-6/+0
tdb_transaction_lock() and tdb_transaction_unlock() do nothing if we hold the allrecord lock. However, the two locks don't overlap, so this is wrong. This simplification makes the transaction lock a straight-forward nested lock. There are two callers for these functions: 1) The transaction code, which already makes sure the allrecord_lock isn't held. 2) The traverse code, which wants to stop transactions whether it has the allrecord lock or not. There have been deadlocks here before, however this should not bring them back (I hope!) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: cleanup: tdb_nest_lock/tdb_nest_unlockRusty Russell3-45/+67
Because fcntl locks don't nest, we track them in the tdb->lockrecs array and only place/release them when the count goes to 1/0. We only do this for record locks, so we simply place the list number (or -1 for the free list) in the structure. To generalize this: 1) Put the offset rather than list number in struct tdb_lock_type. 2) Rename _tdb_lock() to tdb_nest_lock, make it non-static and move the allrecord check out to the callers (except the mark case which doesn't care). 3) Rename _tdb_unlock() to tdb_nest_unlock(), make it non-static and move the allrecord out to the callers (except mark again).

2010-02-17tdb: cleanup: rename global_lock to allrecord_lock.Rusty Russell5-29/+29
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. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: cleanup: rename GLOBAL_LOCK to OPEN_LOCK.Rusty Russell3-17/+17
The word global is overloaded in tdb. The GLOBAL_LOCK offset is used at open time to serialize initialization (and by the transaction code to block open). Rename it to OPEN_LOCK. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: make _tdb_transaction_cancel static.Rusty Russell2-2/+1
Now tdb_open() calls tdb_transaction_cancel() instead of _tdb_transaction_cancel, we can make it static. Signed-off-by: Rusty Russell<rusty@rustcorp.com.au>
2010-02-17tdb: cleanup: split brlock and brunlock methods.Rusty Russell7-117/+235
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.

AC_SIGNAL_TYPE is already obsolete in autoconf. C89 requires signal handlers to return void, only K&R returned int.
