2007-10-10	r14916: print errno so I can work out why OpenBSD is failing the test for tdb	Andrew Tridgell	1	-1/+2
	in the build farm. msync() is failing. (This used to be commit 4c3f3c414135c2b8fa9ea11a156246b56285b84f)
2007-10-10	r14799: added a tdb_get_seqnum() call, and the TDB_SEQNUM flag. This allows	Andrew Tridgell	1	-0/+6
	for an extremely lightweight test to see if a tdb has possibly changed. (This used to be commit f325ba605ccceca63712c0f2c98961e35e437b3d)
2007-10-10	r13283: added two optimisations to the tdb transactions code. The first is to	Andrew Tridgell	1	-1/+36
	more agressively coalesce entries in the linked list of the undo log. The second is to ensure that writes during a transaction into the hash table don't cause the size of the undo log linked list to grow. These optimisations don't affect Samba much, but they make a huge difference to the use of ldb in kde (This used to be commit a37d9434d1fa181fd3d060ad032ee4ec5135fc52)
2007-10-10	r10891: I noticed that the secrets.db was not being backed up on my system due	Andrew Tridgell	1	-0/+9
	to msync/mmap not changing the mtime of the file. This patch ensures that for successfully completed transactions we update the mtime. I don't do this on all tdb writes as its too expensive, but doing it just on transactions is bearable, as those cost quite a lot anyway. (This used to be commit b2934732dd62f705f59c124f19460c5436a9a422)
2007-10-10	r10492: work around a bug in solaris which cases lock upgrades to fail with	Andrew Tridgell	1	-1/+1
	EDEADLK even when progress can be made. This is not a good solution, but I can't find anything better. (This used to be commit 980dd17f7d0a622cd772afc9ba15e50007ad9c6e)
2007-10-10	r10483: fixed some uninitialised variables warnings	Andrew Tridgell	1	-1/+1
	(This used to be commit 315653cf1ecc11c435ee35b20e6cf9c73a67fa68)
2007-10-10	r10469: use the older style of structure initialisation for tdb to make it	Andrew Tridgell	1	-6/+6
	more portable. tdb is used in more than just Samba4, and I think the portability/readability balance is a bit different (This used to be commit fc692dc61f06d61cb9126d2a8ccc240cecd11da6)
2007-10-10	r10468: - terminate tdbtorture quickly when an error is detected	Andrew Tridgell	1	-0/+4
	- more workarounds for aix not handling malloc of size 0 (This used to be commit c2b1739c6389503854f55fa8407c55071781eff4)
2007-10-10	r10465: separate out a read_only db from a read-only traversal to ensure we	Andrew Tridgell	1	-1/+1
	don't end up doing a mmap read only (This used to be commit 294ccfd46a0c4e1af9365d028acdabec03c41ad3)
2007-10-10	r10460: fixed portability of transaction code to systems with integer	Andrew Tridgell	1	-6/+7
	alignment constraints (like sparc) (This used to be commit bce35ad237a55376b6af98416eec92a7c4b422a6)
2007-10-10	r10421: following on discussions with simo, I have worked out a way of	Andrew Tridgell	1	-9/+20
	allowing searches to proceed while another process is in a transaction, then only upgrading the transaction lock to a write lock on commit. The solution is: - split tdb_traverse() into two calls, called tdb_traverse() and tdb_traverse_read(). The _read() version only gets read locks, and will fail any write operations made in the callback from the traverse. - the normal tdb_traverse() call allows for read or write operations in the callback, but gets the transaction lock, preventing transastions from starting inside the traverse In addition we enforce the following rule that you may not start a transaction within a traverse callback, although you can start a traverse within a transaction With these rules in place I believe all the deadlock possibilities are removed, and we can now allow for searches to happen in parallel with transactions (This used to be commit 7dd31288a701d772e45b1960ac4ce4cc1be782ed)
2007-10-10	r10405: added transactions into tdb, and hook them into ldb. See my	Andrew Tridgell	1	-0/+976
	samba-technical posting for more details on the transactions design. This also adds a number of command line arguments to tdbtorture, making it more flexible, and fixes some lock deadlock conditions in the tdbtorture code. (This used to be commit 06bd8abba942ec9f1e23f5c5d546cbb71ca3a701)
