2012-06-22tdb: make TDB_NOSYNC merely disable sync.Rusty Russell1-4/+0
(As suggested by Stefan Metzmacher, based on the change to ntdb.) Since commit ec96ea690edbe3398d690b4a953d487ca1773f1c, we handle the case where a process dies during a transaction commit. Unfortunately, TDB_NOSYNC means this no longer works, as it disables the recovery area as well as the actual msync/fsync. We should do everything except the syncs. This also means we can do a complete test with $TDB_NO_FSYNC set; just to get more complete coverage, we disable it explicitly for one test (where we override the actual sync calls anyway).

2012-06-22autobuild: always set TDB_NO_FSYNC.Rusty Russell1-0/+4
Then we unset it inside the tdb test target itself. This means that new code can't accidently forget it, and we can set it in the 'buildnice' script on sn-devel, for example. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

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).

2010-12-10build: introduce SAMBA_CHECK_PYTHON_HEADERSMatthieu Patou1-1/+1
This function is a wrapper around waf's check_python_header. It avoids searching more than once for the headers bringing a small speed improvement and a better lisibility of the logs. But it's mainly to avoid a nasty bug when python libraries are in path pointed by python_LIBPL (ie. /usr/local/lib/python2.6/config/) instead of python_LIBDIR (ie. /usr/local/lib). On the first call waf will correctly find that in order to link with python libs it needs to add -L$python_LIBPL. But on the next calls of check_python_headers, waf will use both the current library path value (ie. -L/usr/local/lib/python2.6/config) and -L$python_LIBDIR (ie. /usr/local/lib/) which will make him beleive that python libraries are in $python_LIBDIR which at the end will make the final link test fails in check_python_headers as it will not use the good directory. So by avoiding calling check_python_headers more than once we avoid making waf fooling itself.
2010-12-09waf: remove the restriction that private libraries must not have a vnumAndrew Tridgell1-3/+1

2010-12-09waf-abi: auto-generate per-symbol versions from ABI filesAndrew Tridgell1-1/+1
This changes our version-script generation to use the ABI files that are saved in git with each version number change of our public libraries. We use these ABI files to generate a linker version script that gives the exact version number that each symbol was introduced. This provides us with automatic fine grained symbol versioning.

2010-09-27tdb: TDB_INCOMPATIBLE_HASH, to allow safe changing of default hash.Rusty Russell1-1/+1
This flag to tdb_open/tdb_open_ex effects creation of a new database: 1) Uses the Jenkins lookup3 hash instead of the old gdbm hash if none is specified, 2) Places a non-zero field in header->rwlocks, so older versions of TDB will refuse to open it. This means that the caller (ie Samba) can set this flag to safely change the hash function. Versions of TDB from this one on will either use the correct hash or refuse to open (if a different hash is specified). Older TDB versions will see the nonzero rwlocks field and refuse to open it under any conditions. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-09-27tdb: add Bob Jenkins lookup3 hash as helper hash.Rusty Russell1-2/+2
This is a better hash than the default: shipping it with tdb makes it easy for callers to use it as the hash by passing it to tdb_open_ex().

2010-08-14tdb: workaround starvation problem in locking entire database.Rusty Russell1-1/+1
We saw tdb_lockall() take 71 seconds under heavy load; this is because Linux (at least) doesn't prevent new small locks being obtained while we're waiting for a big log. The workaround is to do divide and conquer using non-blocking chainlocks: if we get down to a single chain we block. Using a simple test program where children did "hold lock for 100ms, sleep for 1 second" the time to do tdb_lockall() dropped signifiantly. There are ln(hashsize) locks taken in the contended case, but that's slow anyway. More analysis is given in my blog at http://rusty.ozlabs.org/?p=120 This may also help transactions, though in that case it's the initial read lock which uses this gradual locking routine; the update-to-write-lock code is separate and still tries to update in one go. Even though ABI doesn't change, minor version bumped so behavior change can be easily detected. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2010-04-20tdb: update tdb ABI to use hide_symbols=TrueAndrew Tridgell1-1/+2
We now use -fvisibilty=hidden to hide symbols from outside the tdb shared library. This also moved tdb_transaction_recover() into the tdb_private.h header, as it should never have been a public API. For that reason we are changing the version number. We're only doing a minor version increment as it is extremely unlikely that anyone was actually using tdb_transaction_recover() as its locking requirements were rather unusual.
