2013-02-05tdb: Remove "header" from tdb_contextVolker Lendecke1-6/+6
header.hash_size was the only thing we ever referenced outside of tdb_open_ex and its direct callees. So this shrinks the tdb_context by 164 bytes.

This avoids a tdb_fetch, thus a malloc/memcpy/free in the tdb_store path

2010-05-05tdb: fix short write logic in tdb_new_databaseRusty Russell1-1/+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.

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>
2010-02-17tdb: cleanup: rename global_lock to allrecord_lock.Rusty Russell1-1/+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. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: cleanup: split brlock and brunlock methods.Rusty Russell1-2/+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.

2009-11-20tdb: add TDB_DISALLOW_NESTING and make TDB_ALLOW_NESTING the default behaviorStefan Metzmacher1-0/+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

2009-10-22lib/tdb: wean off TDB_ERRCODE.Rusty Russell1-3/+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. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-10-22lib/tdb: TDB_TRACE support (for developers)Rusty Russell1-23/+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. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2008-12-16imported the tdb_repack() code from CTDBAndrew Tridgell1-0/+89
The tdb_repack() function repacks a TDB so that it has a single freelist entry. The file doesn't shrink, but it does remove all freelist fragmentation. This code originated in the CTDB vacuuming code, but will now be used in ldb to cope with fragmentation from re-indexing
