2010-02-24tdb: remove lock opsRusty Russell1-2/+0
Now the transaction code uses the standard allrecord lock, that stops us from trying to grab any per-record locks anyway. We don't need to have special noop lock ops for transactions. This is a nice simplification: if you see brlock, you know it's really going to grab a lock. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: cleanup: split brlock and brunlock methods.Rusty Russell1-1/+2
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.

2009-10-22lib/tdb: wean off TDB_ERRCODE.Rusty Russell1-16/+19
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. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-07-30If the record is at the end of the database, pretending it has length 1Rusty Russell1-4/+1
might take us out-of-bounds. Only pretend to be length 1 for the malloc.
