916995236e ITS#7364 also close the mutexes as needed
Otherwise a process that opens and closes an env more than once
will leak mutex handles. (WIN32/BSD)

f114fec545 Loop thru all DBs and show their stats
This is quick and dirty, should be integrated into mdb_stat.

14fb1f59c7 Append tweaks, page_split fixes
Append mode now does no key comparisons, input must be in sorted order.
page_split was not updating cursor parents correctly.

7e9a6134fd Make sure cursor's DB is init'd if STALE. 2012-07-17 04:04:52 -07:00

a0993354a6 Don't use env-private copy of DB root nodes.
Just lookup the DB roots as needed. When many DBs are in use,
most of the copies won't be referenced in a given txn, and
there's a bad race condition in the copy routine.

433105f09b Fix: avoid direct reference to meta pages

df7ddb6bf4 Add MDB_NOMETASYNC env option.
Just a trial. This may not make sense if we decide to split the
meta pages into their own separate file, to allow meta traffic to
reside on a separate spindle.

b802bcf704 Partial revert of 13c663f666
Don't re-use free pages so soon; that leaves us vulnerable to
DB corruption if data syncs successfully but meta doesn't.

20baad4a20 libmdb: midl.h namespace cleanup.
Prefix ID, NOID, ID2, IDL, ID2L with 'MDB_'.
Also drop bdb from file description.

8e1ebbb4a8 libmdb: Don't open datafile twice when not needed.
If the database is opened with MDB_RDONLY or MDB_NOSYNC,
instead use the same file descriptor for me_mfd and me_fd.

Also factor out Windows/Unix error handling after open.

4a0b30499c libmdb: Do not use the MDB_txbody.mtb_txnid field.
Get txn->mt_txnid from the meta page instead.  Otherwise it
and txn->mt_toggle could become inconsistent, since read-only
txns fetched both from MDB_txbody without mutex proteciton.
