* tdb: move the original abi_checks script to script/abi_checks_gcc.shMichael Adam2009-08-301-0/+0

* tdb: run abi_checks as part of "make test".Michael Adam2009-08-301-0/+2
| | | | | | | Strange: I had to place "test:: abi_checks" before the main "test::" target here, otherwise the abi checks would not get run. Michael
* tdb: remove files generated by "make abi_checks" in "make clean".Michael Adam2009-08-301-0/+2

* tdb: add a target "abi_checks" to tdb.Michael Adam2009-08-301-0/+4
| | | | | | Simply run "make abi_checks" to call the abi check script appropriately. Michael
* tdb: add script/abi_checks.sh. check for abi changes without gcc magic.Michael Adam2009-08-301-0/+91
| | | | | | | | | USAGE: abi_checks.sh LIBRARY_NAME header1 [header2 ...] This creates symbol signature lists using the mksyms and mksigs scripts and compares them with the checked in lists. Michael
* tdb: add script to extract signatures from header files.Michael Adam2009-08-301-0/+178
| | | | | | | | | | | | This produces output like the output gcc produces when invoked with the -aux-info switch. Run like this: cat include/tdb.h | ./script/mksigs.pl This simple parser is probably too coarse to handle all possible header files, but it treats tdb.h correctly... Michael

* lib/tdb: don't overwrite TDBs with different version numbers.Rusty Russell2009-08-281-5/+7

* There is one signedness issue in tdb which prevents traverses of TDB recordsRusty Russell2009-08-061-9/+21
| | | | | | | | | | | over the 2G offset on systems which support 64 bit file offsets. This fixes that case. On systems with 32 bit offsets, expansion and fcntl locking on these records will fail anyway. SAMBA already does '#define _FILE_OFFSET_BITS 64' in config.h (on my 32-bit x86 Linux system at least) to get 64 bit file offsets. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

* tdb: Reimplementation of Metze's "lib/tdb: if we know pwrite and pread are ↵Rusty Russell2009-07-311-5/+10
| | | | | | | | | | | | | | | | | | | thread/fork safe tdb_reopen_all() should be a noop". This version just wraps the reopen code, so we still re-grab the lock and do the normal sanity checks. The reason we do this at all is to avoid global fd limits, see: http://forums.fedoraforum.org/showthread.php?t=210393 Note also that this whole reopen concept is fundamentally racy: if the parent goes away before the child calls tdb_reopen_all, the database can be left without an active lock and another TDB_CLEAR_IF_FIRST opener will clear it. A fork_with_tdbs() wrapper could use a pipe to solve this, but it's hardly elegant (what if there are other independent things which have similar needs?).

| | | | | | | | | | tdb_reopen_all() should be a noop" This reverts commit e17df483fbedb81aededdef5fbb6ae1d034bc2dd. tdb_reopen_all also restores the active lock, required for TDB_CLEAR_IF_FIRST. Signed-off-by: Stefan Metzmacher <metze@samba.org>

| | | | | | | | | | | | | | | | | | 54a51839ea65aa788b18fce8de0ae4f9ba63e4e7 "Make tdb transaction lock recursive (samba version)" was broken: I "cleaned it up" and prevented it from ever unlocking. To see the problem: $ bin/tdbtorture -s 1248142523 tdb_brlock failed (fd=3) at offset 8 rw_type=1 lck_type=14 len=1 tdb_transaction_lock: failed to get transaction lock tdb_transaction_start failed: Resource deadlock avoided My testcase relied on the *count* being correct, which it was.

* Make tdb transaction lock recursive (samba version)Rusty Russell2009-07-203-21/+20
| | | | | | | | | | | | | | | | | | | This patch replaces 6ed27edbcd3ba1893636a8072c8d7a621437daf7 and 1a416ff13ca7786f2e8d24c66addf00883e9cb12, which fixed the bug where traversals inside transactions would release the transaction lock early. This solution is more general, and solves the more minor symptom that nested traversals would also release the transaction lock early. (It was also suggestd in Volker's comment in 6ed27ed). This patch also applies to ctdb, if the traverse.c part is removed (ctdb's tdb code never received the previous two fixes). Tested using the testsuite from ccan (adapted to the samba code).

* Add exports file and abi checker for tdbtdb-1.1.5Simo Sorce2009-06-157-3/+172
| | | | | | | | This is a first attempt at exporting symbols only for public functions We also provide a rudimentary ABI checker that tries to check that function signatures are not changed by mistake. Given our use of macros this is not an API checker. It's all based on tdb.h contents and the gcc -aux-info option

* overallocate all records by 25%Andrew Tridgell2009-06-011-0/+3
| | | | | | | | This greatly reduces the fragmentation of databases where records tend to grow slowly by a small amount each time. The case where this is most seen is the ldb index records. Adding this overallocation reduced the size of the resulting database by more than 20x when running a test that adds 10k users.
* auto-repack in transactions that expand the tdbAndrew Tridgell2009-06-011-0/+12
| | | | | | The idea behind this is to recover from badly fragmented free lists. Choosing the point where the file expands is fairly arbitrary, but seems to work well.

* | make TDB_NOSYNC affect all the fsync/msync calls in transactionsAndrew Tridgell2009-05-281-5/+7
|/ | | | | | During a transaction commit tdb normally uses fsync/msync calls to make it crash safe. This can be disabled using the TDB_NOSYNC flag, but it wasn't disabling all the code paths that caused a fsync/msync.
