2007-10-10r10524: SAFE_FREE() in tdb does not need the discard_const_p()Andrew Tridgell1-10/+1
the discard_const_p() was causing problems on openbsd where intptr_t is not defined (This used to be commit f02a92787b179a4070227d87e37b7ac092d9e6eb)
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. (This used to be commit 54203aacd138c30826d54c5d9b6cc8d6e9e270f8)

tdb_traverse_read() for read only databases (This used to be commit 9b53e04377d2ff652c4a9496798d2e3aa0dccab3)
2007-10-10r10421: following on discussions with simo, I have worked out a way ofAndrew Tridgell7-29/+100
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)
2007-10-10r10405: added transactions into tdb, and hook them into ldb. See myAndrew Tridgell10-66/+1138
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)

2007-10-10r10253: a fairly large tdb cleanup and re-organise. Nearly all of this changeAndrew Tridgell11-2395/+2128
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. (This used to be commit 4673cdd0d261614e707b72a7a348bb0e7dbb2482)

make sure we don't walk off the end of the hash array (This used to be commit 3c32f24e2c6a99ec294fb16e1684cd22b08f2df4)

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)

added a tdb optimisation that speeds up non-indexed ldb by a large margin (often 10x or more). I'd be interested in any comments on the safety of this optimisation. See the comment in the code for an explanation. (This used to be commit 7f9efaceb6d6dfc0c82923344cc45ec34493f2ed)

2007-10-10r7276: - moved static tdb function ltdb_dn_fold() into common/ so that it can beDerrell Lipman1-1/+10
called from multiple backends. (ldb_sqlite3 needs it too.) Added parameter for a callback function that determines whether an attribute needs case folding. - begin to prepare for sqlite3 in build process - work-in-progress updates, on ldb_sqlite3 (This used to be commit a80bced0b96ffb655559a43cf7f4d7a34deb5a7d)
2007-10-10r6528: - in tdb_fetch() we effectively disallowed zero length records byAndrew Tridgell1-7/+4
returning NULL/0, which is the same as we used for a failure. Having to look at tdb->ecode (which we never do) is too error prone. Instead, tdb_fetch() should behave like malloc() and talloc(), where zero length is not special and malloc(0) returns a valid pointer. - similarly in data_blob(), asking for data_blob(NULL, 0) should return a zero blob, but asking for data_blob(ptr, 0) should return a zero length blob with a valid pointer, just like talloc() and malloc() This change fixes the SummaryInformation stream stored in the tdb backend when manipulated from w2k. The w2k client was using SET_EOF_INFORMATION to create a zero-length stream, which we return STATUS_NOT_FOUND on, as the tdb_fetch() gave us back a NULL/0 blob, which we returned as not-found (This used to be commit 162bbe4402b9de6ac06103df904b9fc204fbff29)

2007-10-10r5298: - got rid of pstring.h from includes.h. This at least makes it a bitAndrew Tridgell2-0/+3
less likely that anyone will use pstring for new code - got rid of winbind_client.h from includes.h. This one triggered a huge change, as winbind_client.h was including system/filesys.h and defining the old uint32 and uint16 types, as well as its own pstring and fstring. (This used to be commit 9db6c79e902ec538108d6b7d3324039aabe1704f)
2007-10-10r5296: - only include the tdb headers where they are neededAndrew Tridgell3-2/+3
- removed the u32 hack in events.c as I think this was only needed as tdb.h defines u32. Metze, can you check that this hack is indeed no longer needed on your suse system? (This used to be commit 6f79432fe656164d4770dbce114a30dda5e7bf9a)
