2009-08-30One would expect I could spell my name...Michael Adam1-1/+1
2009-08-30tdb: move the original abi_checks script to script/abi_checks_gcc.shMichael Adam1-0/+0
Michael
2009-08-30tdb: run abi_checks as part of "make test".Michael Adam1-0/+2
Strange: I had to place "test:: abi_checks" before the main "test::" target here, otherwise the abi checks would not get run. Michael
2009-08-30tdb: remove files generated by "make abi_checks" in "make clean".Michael Adam1-0/+2

2009-08-30tdb: add a target "abi_checks" to tdb.Michael Adam1-0/+4
Simply run "make abi_checks" to call the abi check script appropriately. Michael
2009-08-30tdb: add script/abi_checks.sh. check for abi changes without gcc magic.Michael Adam1-0/+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
2009-08-30tdb: add script to extract signatures from header files.Michael Adam1-0/+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

2009-08-28lib/tdb: don't overwrite TDBs with different version numbers.Rusty Russell1-5/+7
In future, this may happen, and we don't want to clobber them. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-08-06Add define guards around otherwise unused variable.Jeremy Allison1-0/+3
Jeremy.
2009-08-06There is one signedness issue in tdb which prevents traverses of TDB recordsRusty Russell1-9/+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>
2009-07-31tdb: don't alter tdb->flags in tdb_reopen_all()Rusty Russell1-6/+13
The flags are user-visible, via tdb_get_flags/add_flags/remove_flags. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Stefan Metzmacher <metze@samba.org>
2009-07-31tdb: Reimplementation of Metze's "lib/tdb: if we know pwrite and pread are ↵Rusty Russell1-5/+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?).

2009-07-31tdb: Revert "lib/tdb: if we know pwrite and pread are thread/fork safe ↵Rusty Russell1-5/+0
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>
2009-07-30realloc() has that horrible overloaded free semantic when size is 0:Rusty Russell1-2/+7
current code does a free of the old record in this case, then fail.
2009-07-30If the record is at the end of the database, pretending it has length 1Rusty Russell1-4/+1
might take us out-of-bounds. Only pretend to be length 1 for the malloc.
2009-07-21tdb: fix locking errorRusty Russell1-1/+1
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. Fixing that now. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Michael Adam <obnox@samba.org>
2009-07-20Make tdb transaction lock recursive (samba version)Rusty Russell3-21/+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). Thanks to Michael Adam for feedback. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Michael Adam <obnox@samba.org>

2009-06-17fix release scripts to always git cleanSimo Sorce1-0/+3
This makes sure we do not include foreign object files or other build byproducts by mistake.
2009-06-15Add exports file and abi checker for tdbSimo Sorce7-3/+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

2009-06-01overallocate all records by 25%Andrew Tridgell1-0/+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.
2009-06-01auto-repack in transactions that expand the tdbAndrew Tridgell1-0/+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.

2009-05-28make TDB_NOSYNC affect all the fsync/msync calls in transactionsAndrew Tridgell1-5/+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.
