tdb: add TDB_MUTEX_LOCKING support

2014-05-22T19:05:15+00:00

This adds optional support for locking based on
shared robust mutexes.

The caller can use the TDB_MUTEX_LOCKING flag
together with TDB_CLEAR_IF_FIRST after verifying
with tdb_runtime_check_for_robust_mutexes() that
it's supported by the current system.

The caller should be aware that using TDB_MUTEX_LOCKING
implies some limitations, e.g. it's not possible to
have multiple read chainlocks on a given hash chain
from multiple processes.

Note: that this doesn't make tdb thread safe!

tdb: add TDB_DISALLOW_NESTING and make TDB_ALLOW_NESTING the default behavior

2009-11-20T08:45:36+00:00

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.

tdb: update README a bit

2009-10-28T23:44:34+00:00

While studying tdb, I've noticed a couple of mismatches between readme
and actual code:

- tdb_open_ex changed it's log_fn argument to log_ctx
- there is now no tdb_update(), which it seems was transformed into
  non-exported tdb_update_hash()

There were other mismatches, but I don't remember them now, sorry.

lib/tdb: add tdb_check()

2009-10-21T13:40:34+00:00

ctdb wants a quick way to detect corrupt tdbs; particularly, tdbs with
loops in their hash chains.  tdb_check() provides this.

lib/tdb: TDB_TRACE support (for developers)

2009-10-21T13:30:12+00:00

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 _ 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.

Add tdb_transaction_prepare_commit()

2009-03-31T02:15:54+00:00

Using tdb_transaction_prepare_commit() gives us 2-phase commits. This
allows us to safely commit across multiple tdb databases at once, with
reasonable transaction semantics
