2007-10-10r21722: Add the dead record functionality presented on ↵Volker Lendecke3-6/+186
samba-technical@samba.org. If you do a tdb_set_max_dead(tdb, n), then for this tdb a delete operation will only mark a record as dead and re-use it if a new record is created. The parameter n allows for at most n dead records per hash chain. If this number is exceeded, all dead records are put on the central freelist. Volker (This used to be commit 98a27ab28a3cd554e370a9a0e3652f4dea8749e9)
2007-10-10r21445: Apply tdb_parse_record Tridges error return, merge to 3_0_25 and 4_0Volker Lendecke3-13/+90
(This used to be commit afe7d7855841066b88859976ac748cbf438a9a9f)
2007-10-10r21412: The last patch also incremented the seqnum when tdb_store failed. ↵Volker Lendecke1-8/+10
Not as bad as not doing it at all, but needs fixing. Also simplify the logic, I had missed the "goto out" at the end of the function. Volker (This used to be commit ed30a0ff602d0a1d4409bee4faf12b6979b5f4b8)
2007-10-10r21410: We have to increment the sequence number also when tdb_update_hash()Volker Lendecke1-1/+1
succeeded. Found while testing the brlock seqnum patch. Tridge, please check! Volker (This used to be commit e518c68fc5446304611d096ac2e3cab744734fc3)
2007-10-10r21303: As discussed on samba-technical: Change the static array for the ↵Volker Lendecke4-36/+96
in-memory mirrors of the hash chain locks to a dynamically allocated one. Jeremy, I count on you to revert it if the build farm freaks out, it's after midnight here :-) Volker (This used to be commit 7b5db2e472c7e27231fa432d3930789e708abd09)
2007-10-10r19960: Add code to check for loops in the free list.Jeremy Allison2-1/+109
Should help us validate tdb's against corruption. Jeremy. (This used to be commit bd0710fa09799cb496b1f9f365c57c3b542445f3)
2007-10-10r19428: moved tdbutil.c from lib/tdb/common/ to lib/util/util_tdb.cAndrew Tridgell1-549/+0
tdbutil.c is Samba specific, so should not be part of the generic tdb library (This used to be commit 979dd24f5e44605fc1603b690913b8c31be7478f)
2007-10-10r19425: two more tdb functions from samba3Andrew Tridgell1-0/+11
(This used to be commit c9d9d79c34e8a36a6f684b173b1cc861330adc5c)
2007-10-10r19423: merge some tdb changes from SAMBA_3_0 to SAMBA_4_0Andrew Tridgell4-12/+22
this is in preparation of a merge in the other direction (This used to be commit db3211079fd594aa03c3b9bb3eb6ad86bdd32837)
2007-10-10r19401: make tdb_lockall() much more efficient, and add a tdb_lockall_read()Andrew Tridgell6-68/+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)
2007-10-10r18400: move MAP_FAILED define to lib/replace/system/shmem.hAndrew Tridgell1-4/+0
(This used to be commit 025b142ff268498cfb36fc0e7e9e25a2c5963d38)
2007-10-10r18301: I discovered how to load the warnings from a build farm build intoAndrew Tridgell2-2/+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)
2007-10-10r18160: - pread and pwrite replacements need to be non-staticAndrew Tridgell1-22/+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)
2007-10-10r18129: moved the system includes into libreplace - this gives much moreAndrew Tridgell1-31/+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)
2007-10-10r17930: Merge noinclude branch:Jelmer Vernooij1-1/+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)
2007-10-10r17532: merge from SAMBA_3_0 Revision: 17460Stefan Metzmacher1-0/+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)
2007-10-10r17507: pread and pwrite depends on HAVE_PREAD/HAVE_PWRITE not ↵Simo Sorce1-7/+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)
2007-10-10r16916: Implement metze's proposed changes to the tdb logging API.Andrew Bartlett3-13/+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)
2007-10-10r16776: fix typoStefan Metzmacher1-1/+1
metze (This used to be commit 249bf24a40f78aab181a4cce8c42902859e43238)
2007-10-10r16774: This patch modifies the tdb API to allow the logging function to be usedAndrew Bartlett8-108/+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)
2007-10-10r16043: Fix error messageSimo Sorce1-3/+3
(This used to be commit 2898df2cee22f2d478440e9576bec15140909e45)
2007-10-10r15120: Minimize the diff between Samba3 and Samba4 tdb: In Samba3 we don't ↵Volker Lendecke1-7/+7
allow C++ keywords. Change "private" -> "private_data". Volker (This used to be commit 047671567173e808fece41485bbeaaeebab7d4a2)
2007-10-10r15100: Port the bugfix for #3569 to Samba4Volker Lendecke1-1/+17

2007-10-10r14972: fix an uninitialised warning from ibm checkerAndrew Tridgell1-1/+1
(This used to be commit 9b867d2acffdfdcd5dc1dd5341db19daf11b5e96)
2007-10-10r14916: print errno so I can work out why OpenBSD is failing the test for tdbAndrew Tridgell1-1/+2
in the build farm. msync() is failing. (This used to be commit 4c3f3c414135c2b8fa9ea11a156246b56285b84f)
2007-10-10r14799: added a tdb_get_seqnum() call, and the TDB_SEQNUM flag. This allowsAndrew Tridgell3-1/+63
for an extremely lightweight test to see if a tdb has possibly changed. (This used to be commit f325ba605ccceca63712c0f2c98961e35e437b3d)
2007-10-10r14029: Fix resource leak in error codepath. Coverity CID #64.Jeremy Allison1-2/+6
Jeremy. (This used to be commit d2e9d5b34baee90060ee9131b3da903309625a56)
2007-10-10r13773: Be consistent in the way you get out and free allocated dataSimo Sorce1-2/+2
(This used to be commit 1113d4caa7bea1a7ffb9a50f42c5672bc1d452b4)
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)
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. (This used to be commit b2934732dd62f705f59c124f19460c5436a9a422)
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)
2007-10-10r10496: - added configure test for sys/time.hAndrew Tridgell1-2/+2
- print length of failed locks (This used to be commit 11739ad31d7b3e1cf94ebf395608647e341257c4)
2007-10-10r10495: older redhat boxes need sys/time.h for select()Andrew Tridgell1-0/+3
(This used to be commit a11762e7bc139b0280e457e682722d955b81d8e5)
2007-10-10r10494: - don't generate a tdb log message for any type of failed lock probeAndrew Tridgell1-5/+2
- if the lock upgrade loop ever fails then log a warning (This used to be commit 1b03c4e6c7e89452a835ef5ff39c07f58b715a22)
2007-10-10r10493: we need sys/select.h to enable select() in the solaris workaroundAndrew Tridgell1-0/+3
(This used to be commit 144cc3da5eadf0dcb28ef722feeed813c033e08a)
2007-10-10r10492: work around a bug in solaris which cases lock upgrades to fail withAndrew Tridgell3-1/+28
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)
2007-10-10r10484: try to fix the pread/pwrite declaration problemsAndrew Tridgell1-7/+1
(This used to be commit 196995ea38414ce5a57031c4cdf61b3ed548196a)
2007-10-10r10483: fixed some uninitialised variables warningsAndrew Tridgell2-1/+3
(This used to be commit 315653cf1ecc11c435ee35b20e6cf9c73a67fa68)
2007-10-10r10471: stratos doesn't have getpagesize(), so guess 8k on systems that don'tAndrew Tridgell1-0/+4
have it. Overestimating is harmless. (This used to be commit ab953c8c72060c496876b6f39d388ad2f7e3c7e0)
2007-10-10r10469: use the older style of structure initialisation for tdb to make itAndrew Tridgell2-12/+12
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)
2007-10-10r10468: - terminate tdbtorture quickly when an error is detectedAndrew Tridgell2-0/+8
- more workarounds for aix not handling malloc of size 0 (This used to be commit c2b1739c6389503854f55fa8407c55071781eff4)

(This used to be commit e615f36733966f9992670e3650fbe9b20d7d218c)
2007-10-10r10465: separate out a read_only db from a read-only traversal to ensure weAndrew Tridgell6-12/+13
don't end up doing a mmap read only (This used to be commit 294ccfd46a0c4e1af9365d028acdabec03c41ad3)
2007-10-10r10461: fixed tdb build on systems without stdint.hAndrew Tridgell1-2/+2
(This used to be commit 83168c7e76c7e3adcdb0eec1611827d4db09f858)
2007-10-10r10460: fixed portability of transaction code to systems with integerAndrew Tridgell1-6/+7
alignment constraints (like sparc) (This used to be commit bce35ad237a55376b6af98416eec92a7c4b422a6)

2007-10-10r10424: for caller convenience, automatically turn a tdb_traverse() into aAndrew Tridgell1-0/+4
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)
