* r19960: Add code to check for loops in the free list.Jeremy Allison2007-10-102-1/+109
| | | | | | Should help us validate tdb's against corruption. Jeremy. (This used to be commit bd0710fa09799cb496b1f9f365c57c3b542445f3)
* r19428: moved tdbutil.c from lib/tdb/common/ to lib/util/util_tdb.cAndrew Tridgell2007-10-101-549/+0
| | | | | | tdbutil.c is Samba specific, so should not be part of the generic tdb library (This used to be commit 979dd24f5e44605fc1603b690913b8c31be7478f)
* r19425: two more tdb functions from samba3Andrew Tridgell2007-10-101-0/+11

* r19423: merge some tdb changes from SAMBA_3_0 to SAMBA_4_0Andrew Tridgell2007-10-104-12/+22
| | | | | this is in preparation of a merge in the other direction (This used to be commit db3211079fd594aa03c3b9bb3eb6ad86bdd32837)
* r19401: make tdb_lockall() much more efficient, and add a tdb_lockall_read()Andrew Tridgell2007-10-106-68/+139
| | | | | | call which does a read lock on all chains. These will be used to make ldb searches more efficient (This used to be commit de664ec1f8cf179f1d650563272c0de3f7636e2b)

* r18301: I discovered how to load the warnings from a build farm build intoAndrew Tridgell2007-10-102-2/+2
| | | | | | | | | emacs compile mode (hint, paste to a file, and compile as "cat filename"). This allowed me to fix nearly all the warnings for a IA_64 SuSE build very quickly. (This used to be commit eba6c84efff735bb0ca941ac4b755ce2b0591667)
* r18160: - pread and pwrite replacements need to be non-staticAndrew Tridgell2007-10-101-22/+0
| | | | | | | | | | | | | | | | - replacing rename() is pointless - all platforms have it (and the #define of rename breaks some code) - use system/locale.h in snprintf.c - fix passwd.h for initgroups - stdlib is in replace.h, not needed elsewhere - fix the initgroups replacement - fix mapping of dl functions to rep_* (This used to be commit 57cd0ca176387d6a3acabf9fedeef4f2a3a3dad7)
* r18129: moved the system includes into libreplace - this gives much moreAndrew Tridgell2007-10-101-31/+4
| | | | | | | isolation of our portability environment from the main code, and also simplifies the includes system (no separate #ifdef _SAMBA_BUILD for tdb. ldb etc now) (This used to be commit 77d1a468e06290aba789e2f3affc769fc5159a21)
* r17930: Merge noinclude branch:Jelmer Vernooij2007-10-101-1/+1
| | | | | | | * Move dlinklist.h, smb.h to subsystem-specific directories * Clean up ads.h and move what is left of it to dsdb/ (only place where it's used) (This used to be commit f7afa1cb77f3cfa7020b57de12e6003db7cfcc42)
* r17532: merge from SAMBA_3_0 Revision: 17460Stefan Metzmacher2007-10-101-0/+1
| | | | | | | | | | First step at fixing the build breakage with the groupmapping test. On Linux, F_RDLCK is defined to 0, for example NetBSD has it at 1. Still does not work fully though. Still investigating. metze (This used to be commit af08e56442367b5d803f61b8554d85e2fe0ce7e9)
* r17507: pread and pwrite depends on HAVE_PREAD/HAVE_PWRITE not ↵Simo Sorce2007-10-101-7/+0
| | | | | | | | | HAVE_PREAD_DECL/HAVE_PWRITE_DECL and common/io.h already defines pread and pwrite as static if they are not. remove unneded defines (This used to be commit 941f680453a081d51f6499f9b5dc06c7e6640334)
* r16916: Implement metze's proposed changes to the tdb logging API.Andrew Bartlett2007-10-103-13/+16
| | | | | | | | This clearly links the log function with its private pointer, and makes the argument list for tdb_open_ex a bit shorter. Andrew Bartlett (This used to be commit 5d5503e8d8a10ead3ef21a5ffda52cadb9a07727)

* r16774: This patch modifies the tdb API to allow the logging function to be usedAndrew Bartlett2007-10-108-108/+116
| | | | | | | | | | | | | | | | | as part of ldb. This allows tdb failures to be passed all the way up to Samba's DEBUG system, which allowed easier debugging. Unfortunately I had to extend the tdb API, as the logging function didn't have a context pointer. I've worked over the 'debug levels' in TDB. Most of them were 0, which didn't seem right, as some were trace-like messages. We didn't see any of these previously, except when accessing TDB directly. Andrew Bartlett (This used to be commit 58898092c1ce043f6d698db5065f372b79109e22)

| | | | (This used to be commit 1113d4caa7bea1a7ffb9a50f42c5672bc1d452b4)
* r13283: added two optimisations to the tdb transactions code. The first is toAndrew Tridgell2007-10-101-1/+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)
* r10891: I noticed that the secrets.db was not being backed up on my system dueAndrew Tridgell2007-10-101-0/+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)
* r10524: SAFE_FREE() in tdb does not need the discard_const_p()Andrew Tridgell2007-10-101-10/+1

* r10522: finally got the locking working on solaris10. This adds a read lock onAndrew Tridgell2007-10-101-0/+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)

* r10421: following on discussions with simo, I have worked out a way ofAndrew Tridgell2007-10-107-29/+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)
* r10405: added transactions into tdb, and hook them into ldb. See myAndrew Tridgell2007-10-1010-66/+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.

* r10253: a fairly large tdb cleanup and re-organise. Nearly all of this changeAndrew Tridgell2007-10-1011-2395/+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.

| | | | | | | | | | | 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)
