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>
2012-03-29cast: make sure suncc sees a constant.Rusty Russell2-8/+22
cast_const() et. al. are supposed to be a constant expression, so you can do things like: static char *p = cast_const(char *, (const char *)"hello"); Unfortunately, a cast to intptr_t and arithmetic makes suncc reject it as a constant expression. We need the cast, because (1) the expression could be a void *, so we can't just add to it, and (2) gcc complains with -Wcast-qual without it. So instead of adding BUILD_BUG_OR_ZERO, we use a ? :, which keeps everyone happy.

2012-03-29cast: test/compile_fail-cast_static.c should fail without COMPOUND_LITERALS.Rusty Russell1-3/+9
It still gave a warning on gcc, because casting a char to a char* gives a warning. Not so on sun CC. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> (Imported from CCAN commit 6569a707d169a629e25e10710c760c8dc84525c7)
2012-03-29tdb2: fix prototype in tdb1 code.Rusty Russell1-5/+5
We were handing an int-returning function where we should hand an enum TDB_ERROR returning function. Worse, it was returning 0/-1 instead of 0/TDB_ERR_*. Fortunately, it's only compared against success, but the Solaris compiler warns about it, and it's not correct anyway. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

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>

2012-03-22lib/tdb2: fix -Wcast-qual warnings.Rusty Russell15-59/+33
We use tdb_mkdata() to get rid of many of them from the tests, and explicit cast_const() in a few places. tlist_for_each() still causes a warning, but that needs to be fixed in CCAN.

2012-03-22lib/tdb2: fix OpenBSD incoherent mmap (tdb2 version)Rusty Russell3-8/+31

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/ccan/failtest: compile fix for OpenBSDRusty Russell3-0/+17
OpenBSD doesn't idempotent-wrap sys/mman.h, so when we #define mmap to an alternative, it fails to compile when sys/mman.h is included again. Workaround is not to #define mmap to add arguments on Open BSD. (Imported from CCAN commit e18e80fe175422d26efe689addc0f67bdba0e097) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

CCAN includes a little utility called "namespacize" which prepends ccan_ to all public methods of a module, and fixes up any dependencies it finds. It's a little primitive, but it works here. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
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>

CommonCrypto/CommonDigest is available on Mac and there is function in the libc for MD5 calculation. MD5Final is a C define of CC_MD5_Final. Under some circumstance we have the symbol defined twice in samba binaries on Snow Leopard at least. By detecting CommonCrypto/CommonDigest we end up always using the system version if available.
