2013-02-05tdb: Remove "header" from tdb_contextVolker Lendecke1-2/+2
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.

2010-02-17tdb: cleanup: split brlock and brunlock methods.Rusty Russell1-2/+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 Russell1-1/+2
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 Russell1-4/+19
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>
2009-08-06There is one signedness issue in tdb which prevents traverses of TDB recordsRusty Russell1-9/+21
over the 2G offset on systems which support 64 bit file offsets. This fixes that case. On systems with 32 bit offsets, expansion and fcntl locking on these records will fail anyway. SAMBA already does '#define _FILE_OFFSET_BITS 64' in config.h (on my 32-bit x86 Linux system at least) to get 64 bit file offsets. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-07-20Make tdb transaction lock recursive (samba version)Rusty Russell1-16/+6
This patch replaces 6ed27edbcd3ba1893636a8072c8d7a621437daf7 and 1a416ff13ca7786f2e8d24c66addf00883e9cb12, which fixed the bug where traversals inside transactions would release the transaction lock early. This solution is more general, and solves the more minor symptom that nested traversals would also release the transaction lock early. (It was also suggestd in Volker's comment in 6ed27ed). This patch also applies to ctdb, if the traverse.c part is removed (ctdb's tdb code never received the previous two fixes). Tested using the testsuite from ccan (adapted to the samba code). Thanks to Michael Adam for feedback. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Michael Adam <obnox@samba.org>
