2001-12-10tdb_open_ex should always "goto fail" in case of error, rather thanMartin Pool1-1/+2
just returning. I don't think this would leak at the moment, but it's an accident waiting to happen. (This used to be commit fe901ec194d1b8ef94386b097e72508075eb8a54)

2001-12-10tdb_open_ex: Continue previous refactoring so that we consistentlyMartin Pool1-12/+12
just say "tdb" not "&tdb". (This used to be commit fac685d30f58c25d73d1690ed008c797291558e4)
2001-12-10tdb_open_ex: Refactor to use a pointer to tdb, rather than an autoMartin Pool1-57/+58
tdb, to be consistent with the rest of the code. (This used to be commit d159415049c25caeaf01b6bc947da3472c54d1f8)
2001-12-04Put back changes to set errno, which seem to do no harm.Martin Pool1-12/+42

2001-12-04Implement suggestion from tridge to leave the old tdb_open interfaceMartin Pool1-2/+9
as it was, and add tdb_open_ex() which takes a log callback. I guess this makes more sense since it's a public interface. (This used to be commit 391a65395e6cdc0300f81eb1072a3366cacd1203)
2001-12-04Better error handling:Martin Pool1-66/+124
- tdb_open api changed so that you now pass an error handling callback when opening the file, so that errors detected during opening have somewhere to go. (All calls from the body of Samba to this function go through a wrapper in tdbutil, which has been updated.) - Clean up logic for deciding how to open tdb. Emit log messages if something goes wrong (e.g. bad magic.) - tdbtool now logs errors to stderr. (This used to be commit 0aa800618eab1043d802c04fb1d125cd07936769)
2001-12-04Set errno in tdb_open in cases where we detect an error in opening theMartin Pool1-11/+33
database, but no underlying system call sets errno. The particular case I had was a mangled .tdb, but there are others. For this one, set EIO. It's a shame Unix messages aren't more detailed -- "bad data format" would be better. (This used to be commit 5630a988be05c21b60aba6304d4aaadce6024817)
2001-11-09Removed #ifdef TDB_DEBUG around tdb_dump_all() and tdb_printfreelist()Tim Potter1-5/+3
so that tdbtool can be compiled without having to make clean. (This used to be commit dad688d8c6b3c98173a846ad833599a4016d2e1a)
2001-10-16Don't core dump when using spinlocks on a read-only tdb. Unfortunately thisJeremy Allison1-4/+16
means that a read-write opener and a read-only opener are using different locking mechanisms - this needs to be addressed, but it's hard as the read-write opener using the spinlocks is usually first, so there's no way to force them to change down to the fcntl method. Read only access is less important anyway and can never corrupt the tdb anyway, so errors in read-only record reads are more tolerable. Jeremy (This used to be commit 21f776df5932e024a0d1fef9097377d35b5cf511)
2001-10-12Fix for tdb_oob() on TDB_INTERNAL databases.Jeremy Allison1-2/+7
Jeremy. (This used to be commit 2b135fba625191a13e4110c68531a0e6d5fb373d)
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)

2001-06-21Ok - 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

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
