2001-10-03Ensure accessing NT member servers works with a Samba PDC. Don'tJeremy Allison1-1/+2
change these timestamp settings without good reason. Remove CLEAR_IF_FIRST flag is tdb is read-only. Jeremy. (This used to be commit a71d9d98b013a6c30fd85524b7cdc929bdbd9bcb)
2001-09-19Put pwrite code back in expand_file.Jeremy Allison1-3/+10
Jeremy. (This used to be commit a3267551d88dffb226e4a1c3852fe9c817517d02)
2001-09-19added a hook to reopen all tdb's after the server forkAndrew Tridgell1-10/+48
this prevents the fd seek pointer problem (This used to be commit f49518e497deeb46292456c3650769d50ec2a955)
2001-09-19Fix based on Andrew's insight as re-using a tdb after fork meansJeremy Allison1-3/+23
parent and child share seek pointer. Damn.... Jeremy. (This used to be commit 0e75c0fc1aa742fb0c29716c99a81cf5b33ef6e6)
2001-09-19Return correct error code on lock fail in tdb_expand.Jeremy Allison1-1/+1
Jeremy. (This used to be commit b45793ec3f6ff04587bee8f463ef6410b06097d6)
2001-09-18Roll back earlier fix after talking with Andrew. The write_lock_record andJeremy Allison1-2/+2
unlock are explicitly non-blocking. I will add a comment to this effect later. Jeremy. (This used to be commit e4b41a8f31729dfec92c4cb1f8b4759446cac0ff)
2001-09-18Fixed a couple of nasty bugs only easily seen with no mmap. Firstly,Jeremy Allison1-2/+4
map_ptr not neccessarily set to NULL if no mmap, secondly, iterating through a tdb was using SETLK, instead of SETLKW - would almost never fail with mmap as the time holding the lock was so short, but was easily seen with read/write. One finaly bug needs tracking down w.r.t. traversal...... Jeremy. (This used to be commit 313c2e8652092a307165b6039dd7dfbbd0754ec3)
2001-08-02Added mmap fix to pass lock test from HP.Jeremy Allison1-115/+222
Ok - now we're no longer trying to reach a silly 1k loc target, change the formatting to be *readable* - eg. change if (x) y else z to be : if (x) y else z and other compact sillyness. Oh look - when I did this I found some areas where we *WEREN'T CHECKING SYSTEM CALL ERROR RETURNS !!!!* CompSci 101 guys....... :-). Jeremy. (This used to be commit 38d2e6983a6be8232ae7ce21a950d69dd95ce3e6)
2001-07-31Fix for rare tdb pattern store failure. Found & fixed by Rusty.Jeremy Allison1-1/+4
Jeremy. (This used to be commit aaa56bb3a3c5f0e4191c9b3efe9b8d92c22cf6c7)
2001-07-25Always check fstat for error.Jeremy Allison1-10/+13
Jeremy. (This used to be commit 34951876a1bfad5aa3fc3bd05b808e150f639a8a)
2001-07-05Fix for enumerating large numbers of users.Jeremy Allison1-1/+1
Jeremy. (This used to be commit c8c138c1fbb49799a2dd4c6e781bd89f51c0c0c5)
2001-06-21Ok - I misspoke.... mmap returns MAP_FAILED, not neccessarily -1 :-).Jeremy Allison1-2/+6
Jeremy. (This used to be commit 2d1c6d1f6b55a0a78eb8afbe16d2ad8b3253a220)
2001-06-21When mmap fails it returns -1 *NOT NULL*.Jeremy Allison1-1/+7
This got regressed somehow..... Jeremy. (This used to be commit b77c8b536d4b6d2162f4932227f01cffb730c645)
2001-06-11Fixed potential free of NULL found by SGI speedshop.Jeremy Allison1-1/+2
Jeremy. (This used to be commit fc7830eec8f5478fc3d3296bb35cb11c94e7d9fa)
2001-05-30- fixed an off-by-1 bug in the delayed deletion code that I believeAndrew Tridgell1-47/+107
was the initial cause of the connections database becoming corrupt. Note that this bug only happens when doing deletions within a traversal, which is why it has only showed up now - added delete within traversal testing to tdbtorture - added a lot more logging to tdb (This used to be commit 6e1277df9d964c615a3ad876d3b89ff8132081c1)
2001-05-30added a tdb_open_log() function that opens a tdb and enables loggingAndrew Tridgell1-1/+1
of messages from the tdb code into the Samba DEBUG() system just call tdb_open_log() instead of tdb_open() to enable this on any tdb (This used to be commit 3ab770484c6775df2c1a6f69427ebe656702c96c)
2001-05-29more portable TDB_LOG macroAndrew Tridgell1-1/+1
(This used to be commit ba106b9b07b23c3dc1b40c8feb10cff173faa07a)
2001-05-28try to make the tailer code much more robust. When a recordAndrew Tridgell1-13/+99
can't be merged don't fail the operation, instead just add it to the free list anyway added logging to tdb (This used to be commit dda086fdf92fded016afc785f7965a375faae5aa)
2001-05-15make sure that when a tdb expands we fill the expanded area, otherwise ↵Andrew Tridgell1-6/+29
ENOSPC could be very bad (This used to be commit b94cfb6843dc7fc985917395d3e0d953501b9197)
2001-05-14Implemented max connections in a similar way to 2.0.x (scan of connection db).Jeremy Allison1-6/+8
This needs testing ! Tidied up tabs in tdb.c. Jeremy. (This used to be commit 0852465053d0c1a23b6cfe6097267291b0595ef8)

2001-01-29Changes from APPLIANCE_HEAD:David O'Neill1-12/+20
source/include/proto.h - make proto source/printing/nt_printing.c source/rpc_server/srv_spoolss_nt.c - Fix for the overwriting of printerdata entries when WinNT and Win2k are modifying printer parameters on PCL printers. Turns out that Win2k creates a printer with a NULL devmode entry and then expects to set it on *OPEN* (yes this is insane). So we cannot return a "default" devmode for a printer - and we must allow an open to set it. source/tdb/tdb.c - Show freelist in an easier format. Show total free. - When storing a new record, allocate memory for the key + data before the tdb_allocate() as if the malloc fails a (sparse) hole is left in the tdb. source/tdb/tdbtool.c - Show freelist in an easier format. Show total free. source/tdb/Makefile - cleaned up Makefile dependancies source/smbd/lanman.c - Fix for Win9x corrupting it's own parameter string. source/printing/printfsp.c source/printing/printing.c source/rpc_server/srv_spoolss_nt.c source/smbd/close.c - Added normal close parameter into print_fsp_end() which treats an abnormal close as error condition and deletes the spool file. (This used to be commit 025f7a092ad258ff774e3f5e53737f8210cc8af6)
2001-01-16Set the tdb->map_ptr to NULL if mmap() returns -1.Tim Potter1-0/+3
(This used to be commit cef7f58ac5cc0c96e1027c7e5ecbb3fb72cb94b6)
2000-12-30The line was:Christopher R. Hertel1-1/+6
struct tdb_traverse_lock tl = { tdb->travlocks.next, 0, 0 }; The IRIX compiler complained that the first initialization value was not a constant and errored out. Here's what it looks like now: struct tdb_traverse_lock tl = { NULL, 0, 0 }; int ret, count = 0; /* This was in the initializaton, above, but the IRIX compiler * did not like it. crh */ tl.next = tdb->travlocks.next; That worked. Chris -)----- (This used to be commit e651d1d642cd1bfac11bec81a30915b95d4424c8)
2000-12-15Added lock backouts on fail.Jeremy Allison1-3/+28
When chaining together long lines of bloody "if" statements, which should logically be separated, and one of them allocates memory, remember to *free* it *WHETHER OR NOT THE IF STATEMENTS SUCCEEDED* !!!! Yes I do consider this a bug in the coding style of Tridge, Rusty, Tim et al. :-). I'm just pissed 'cos this took 4 hours to track down even with an insure error report stating me in the face and also Ben Woodward looking over the code with me :-). Jeremy. (This used to be commit 506b5e34c3ba16768dbc82ba21044787de160c45)
2000-12-13Two tdb bugfixes. First one - ensure that traverse lock is moved before deletingJeremy Allison1-45/+58
dead records, else the record is just marked for deletion, not actually deleted. Second, ensure allocated record is marked as "in use" before free list lock is released, else other processes in the freelist merge code may try and merge it. Jeremy. (This used to be commit dd959fa325c5df8ce0407d8debea76602c8e71cf)
2000-12-11Added Tim's fix for read-only crashes.Jeremy Allison1-0/+2
Jeremy. (This used to be commit cfc62fecdf4c5579ee643df3e701cf6f1fe553ee)
2000-12-07Fixed bug with tdb_next_lock failing when reaching then end of a hashchainJeremy Allison1-9/+10
and the next hashchain is empty. Jeremy (This used to be commit f3b5e2a172a777e1c3bbf6ac72fe5c7cdb8324b3)
2000-12-06Changed to sourceforge tdb code. This includes spinlocks (so we now haveJeremy Allison1-1013/+717
a --with-spinlocks option to configure, this does mean the on-disk tdb format has changed, so 2.2alphaX sites will need to re-create their tdb's. The upside is no more tdb fragmentation and a +5% on netbench. Swings and roundabouts.... Jeremy. (This used to be commit 9dea7b7c257db487f8ced7dad3fce92fba03ea91)
2000-12-05Fixed one tdb_read -> rec_free_read call.Jeremy Allison1-10/+2
Jeremy. (This used to be commit c9884e16fc2d13dd62c5a43633c9a38dadc9822c)
2000-12-05Added sorted freelist neighbour merge code to stop tdb fragmentation.Jeremy Allison1-32/+212
This needs TESTING !!! (It passes tdbtest of course :-). Jeremy. (This used to be commit 7ae54a93e756d927419242adf35f46e91e974573)
2000-12-02Added print_freelist command.Jeremy Allison1-0/+35

(This used to be commit 03453e2ae557d7fa119338b71744822093d2f38a)
2000-10-10got rid of tdb_writelock() and instead lock a chain. tdb_writelock()Andrew Tridgell1-25/+0
is conceptually flawed (This used to be commit 6e4a3585521b7e5928298bd0f1418ff9fbcacfb4)
2000-10-05Herb's fixes for profiling & compiler warnings.Jeremy Allison1-1/+1
Jeremy. (This used to be commit 7914e9351abb5271ebb4990c3b1fe495d15a4eda)
2000-10-02Added debug so if zero length messages get sent we successfully removeJeremy Allison1-3/+7
them (this can happen if smbd processes are shut down at the wrong time). Jeremy. (This used to be commit c1de97f96b8c5ad8e5f01a0d17c6387733769442)
2000-06-15- use read locks when possibleAndrew Tridgell1-42/+44
- don't use as many locks on a store (This used to be commit ee12b10d21022287baf4432d1df743c4b28223b2)
2000-05-12an imcompatible tdb format change (sorry!)Andrew Tridgell1-11/+2
this will give us a much nicer migration path for the proposed semaphore code (This used to be commit 491ab241897a7252fb088c718de4bdf7f43f4ddc)
2000-05-10when creating the database zero the reserved spaceAndrew Tridgell1-0/+8
(This used to be commit a5ca60f62bea988e74e2827fbb848770ac5ae444)
2000-05-10- add some reserved space to every tdb, this will beAndrew Tridgell1-2/+3
used for semaphores and future expansion - update tdb version number to 2 (This used to be commit 5e04885b86791e6ef8b4a316e64d56c6eb05f35d)
2000-05-10Use a prime for default tdb hash size - this makes a difference !Herb Lewis1-1/+1
Jeremy. (This used to be commit 400906e6421c150b591b4bf978a641d5aaf8fd09)
2000-05-01fixed typoAndrew Tridgell1-1/+1
(This used to be commit 5341597de6772027034cad7dacbdbd6d2108332a)
2000-05-01added TDB_INTERNAL, TDB_NOLOCK and TDB_NOMMAP flags.Andrew Tridgell1-40/+63
TDB_INTERNAL replaces the old method of passing a null filename (This used to be commit 8ec815920d46f205b9f3fff82397c731753c3a10)
2000-04-30- removed all our old wildcard matching code and replaced it with aAndrew Tridgell1-20/+15
call to ms_fnmatch(). This also removes all the Win9X semantics stuff and a bunch of other associated cruft. - moved the stat cache code into statcache.c - fixed the uint16 alignment requirements of ascii_to_unistr() and unistr_to_ascii() - trans2 SMB_FIND_FILE_BOTH_DIRECTORY_INFO returns the short name as unicode always (at least thats what NT4 does) - fixed some errors in the in-memory tdb code. Still ugly, but doesn't crash as much (This used to be commit 03e9cea004bbba72161a5323cf3b4556c94aed8e)
2000-04-29put tdb utility functions in a separate fileAndrew Tridgell1-44/+0
