2007-10-10r13283: added two optimisations to the tdb transactions code. The first is toAndrew Tridgell1-1/+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)

the difference between these at all, and in the future the fact that INIT_OBJ_FILES include smb_build.h will be sufficient to have recompiles at the right time. (This used to be commit b24f2583edee38abafa58578d8b5c4b43e517def)

2007-10-10r11567: Ldb API change patch.Simo Sorce1-9/+48
This patch changes the way lsb_search is called and the meaning of the returned integer. The last argument of ldb_search is changed from struct ldb_message to struct ldb_result which contains a pointer to a struct ldb_message list and a count of the number of messages. The return is not the count of messages anymore but instead it is an ldb error value. I tryed to keep the patch as tiny as possible bu as you can guess I had to change a good amount of places. I also tried to double check all my changes being sure that the calling functions would still behave as before. But this patch is big enough that I fear some bug may have been introduced anyway even if it passes the test suite. So if you are currently working on any file being touched please give it a deep look and blame me for any error. Simo. (This used to be commit 22c8c97e6fb466b41859e090e959d7f1134be780)

2007-10-10r10891: I noticed that the secrets.db was not being backed up on my system dueAndrew Tridgell1-0/+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.

2007-10-10r10522: finally got the locking working on solaris10. This adds a read lock onAndrew Tridgell1-0/+12
the transaction lock in tdb_traverse_read(). This prevents a pattern of locks which triggers the deadlock detection code in solaris10. I suspect solaris10 is trying to prevent lock starvation by granting locks in the order they were requested, which makes it much easier to produce deadlocks.

2007-10-10r10421: following on discussions with simo, I have worked out a way ofAndrew Tridgell10-32/+130
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)

2007-10-10r10253: a fairly large tdb cleanup and re-organise. Nearly all of this changeAndrew Tridgell24-2578/+2231
just involves splitting up the core tdb.c code into separate files on logical boundaries, but there are some minor functional changes as well: - move the 'struct tdb_context' into tdb_private.h, hiding it from users. This was done to allow the structure to change without breaking code that uses tdb. - added accessor functions tdb_fd(), tdb_name(), and tdb_log_fn() to access the elements of struct tdb_context that were used by external code but are no longer visible - simplied tdb_append() to use tdb_fetch()/tdb_store(), which is just as good due to the way tdb locks work - changed some of the types (such as tdb_off to tdb_off_t) to make syntax highlighting work better - removed the old optional spinlock code. It was a bad idea. - fixed a bug in tdb_reopen_all() that caused tdbtorture to sometimes fail or report nasty looking errors. This is the only real bug fixed in this commit. Jeremy/Jerry, you might like to pickup this change for Samba3, as that could definately affect smbd in Samba3. The aim of all of these changes is to make the tdb transactions/journaling code I am working on easier to write. I started to write it on top of the existing tdb.c code and it got very messy. Splitting up the code makes it much easier to follow. There are more cleanups we could do in tdb, such as using uint32_t instead of u32 (suggested by metze). I'll leave those for another day.

optimise this case a bit more. The total speedup using non-indexed ldbtest is now around a factor of 80x. The code is ugly as hell, but I think this speed is worth it. Of course, if we only ever do indexed searches in ldb then this doesn't help, but it seems all too common that we get unindexable searches, so the optimisation is worthwhile (This used to be commit 2e14fb893dd9815cdb2488c630131dc549e5c361)
