2012-03-29lib/tdb: Add/expose lock functions to support CTDBAmitay Isaacs1-2/+16
This patch adds two lock functions used by CTDB to perform asynchronous locking. These functions do not actually perform any fcntl operations, but only increment internal counters. - tdb_transaction_write_lock_mark() - tdb_transaction_write_lock_unmark() It also exposes two internal functions - tdb_lock_nonblock() - tdb_unlock() These functions are NOT exposed in include/tdb.h to prevent any further uses of these functions. If you ever need to use these functions, consider using tdb2. Signed-off-by: Amitay Isaacs <amitay@gmail.com>
2012-03-23lib/tdb: fix transaction issue for HAVE_INCOHERENT_MMAP.Rusty Russell1-11/+10
We unmap the tdb on expand, the remap. But when we have INCOHERENT_MMAP (ie. OpenBSD) and we're inside a transaction, doing the expand can mean we need to read from the database to partially fill a transaction block. This fails, because if mmap is incoherent we never allow accessing the database via read/write. The solution is not to unmap and remap until we've actually written the padding at the end of the file.

2012-03-23lib/tdb: fix test/run-die-during-transaction when HAVE_INCOHERENT_MMAP.Rusty Russell1-0/+5
Since we force mmap on, we don't intercept writes to the db, so we never see it in an inconsistent state. #ifdef over the check that we should have recovered it at least once. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-03-23lib/tdb: fix missing return 0 code.Rusty Russell1-1/+1
fde694274e1e5a11d1473695e7ec7a97f95d39e4 made tdb_mmap return an int, but didn't put the return 0 on the "internal db" case. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-03-22lib/tdb: fix OpenBSD incoherent mmap.Rusty Russell4-24/+58
This comment appears in two places in the code (commit 4c6a8273c6dd3e2aeda5a63c4a62aa55bc133099 from 2001): /* * We must ensure the file is unmapped before doing this * to ensure consistency with systems like OpenBSD where * writes and mmaps are not consistent. */ But this doesn't help, because if one process is using mmap and another using pwrite, we get incoherent results. As demonstrated by OpenBSD's failure on the tdb unit tests. Rather than disable mmap on OpenBSD, we test for this issue and force mmap to be enabled. This means that we will fail on very large TDBs on 32-bit systems, but it's better than the horrendous performance penalty on every OpenBSD system.

2012-03-22lib/tdb: fix up run-die-during-transaction test cases on Solaris.Rusty Russell4-5/+4
By using a different include order, we end up with a different version of FILE_OFFSET_BITS (and probably other things) in parts of the test. The different variants get linked together, and the result is weird: the stat returns 0 size. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-03-14lib/tdb: remove unnecessary XOPEN and FILE_OFFSET_BITS defines in test/Rusty Russell17-20/+0
These were relics: they don't need to be defined here as long as we are careful to include the replace headers before any standard headers (we are).

Commit 4d58d0fa8f936e7efdc02e31c053d42a47b3e62a didn't work for lib/tdb outside the build tree: symlink was pointing to wrong place. Copy simplification from lib/tdb2, and fix the build farm.

2012-02-14tdb: build and run unit tests in tdb/test/Rusty Russell1-7/+87
Now we can build the test binaries: the CCAN style is to compile everything called "compile_ok*.c", compile and run everything called "run*.c", compile, link with the module, and run everything called "api*.c", and link any other C files (presumably test helpers) into all the tests. Unfortunately, actually passing that between the various parts of wscript is painful, so I open-coded the names. Also, the tests expect to be run in a (temporary) directory they can pollute, with the test directory found in test/ (to find the canned TDB files, for example).

2012-02-14tdb/test: fix up tests for use in SAMBA tdb code.Rusty Russell5-13/+16
1) Make sure we include "tdb_private.h" first, to get the right headers (esp. the correct setting of _FILE_OFFSET_BITS before unistd.h). 2) Fix 3G file test since expand logic has changed. 3) Fix nested transaction test, since default is to allow nesting. 4) Capture fdatasync, which was slowing down transaction expand.

2012-02-14tdb: wean CCAN-style unit tests off of tap.Rusty Russell25-23/+64

2012-02-14tdb: import unit tests from CCAN into tdb/test/Rusty Russell35-1/+2567
I pulled tdb into CCAN as an experiment a while ago; it doesn't belong there, but it has accumulated some important unit tests. These are copied from CCAN version init-1486-gc438ec1 with #include "../" changed to #include "../common/". Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-02-14tdb: make tdb_private.h idempotent.Rusty Russell1-0/+3
The most convenient way to write unit tests in C is to directly #include the C files (CCAN uses this, for example). That works quite well, but it means that tdb_private.h now needs to be protected against multiple inclusions. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2011-12-21tdb: don't free old recovery area when expanding if already at EOF.Rusty Russell1-17/+30
We allocate a new recovery area by expanding the file. But if the recovery area is already at the end of file (as shown in at least one client case), we can simply expand the record, rather than freeing it and creating a new one.

2011-12-21tdb: use same expansion factor logic when expanding for new recovery area.Rusty Russell3-21/+34
If we're expanding because the current recovery area is too small, we expand only the amount we need. This can quickly lead to exponential growth when we have a slowly-expanding record (hence a slowly-expanding transaction size). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

I came across a tdb which had wrapped to 4G + 4K, and the contents had been destroyed by processes which thought it only 4k long.

2011-04-18tdb_expand: limit the expansion with huge recordsSimo Sorce1-5/+20
ldb can create huge records when saving indexes. Limit the tdb expansion to avoid consuming a lot of memory for no good reason if the record being saved is huge.
2011-04-18tdb: tdb_repack() only when it's worthwhile.Rusty Russell1-6/+31
tdb_repack() is expensive and consumes memory, so we can spend some effort to see if it's worthwhile. In particular, tdbbackup doesn't need to repack: it started with an empty database! Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
