| | | | | | | | | | | | | | | | | | | | 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 Russell2009-12-169-40/+59
| | | | | | | | | | | | | | | 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 Russell2009-12-167-55/+402
| | | | | | | | | | | | | | | | | | 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.

* tdb: fixed the intermittent failure of tdbtorture in the build farmAndrew Tridgell2009-12-161-2/+5
| | | | | | | | | | | | | There was a race condition that caused the torture.tdb to be left in a state that needed recovery. The torture code thought that any message from the tdb code was an error, so the "recovered" message, which is a TDB_DEBUG_TRACE message, marked the run as being an error when it isn't.

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.

The case where this is most seen is the ldb index records. Adding this overallocation reduced the size of the resulting database by more than 20x when running a test that adds 10k users.

Choosing the point where the file expands is fairly arbitrary, but seems to work well. (This used to be ctdb commit 233c52bfb087f636ad61e95c12616c02901f4f83)

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 (This used to be ctdb commit fe3ceb101a5a9c336973c2c6c31406bd8181c2fe)

This can be disabled using the TDB_NOSYNC flag, but it wasn't disabling all the code paths that caused a fsync/msync. (This used to be ctdb commit e03980add02a28609a7a0a0c87ebc85419b98144)
