2010-09-27tdb: fix non-WAF build, commit 1.2.6 ABI file.Rusty Russell2-1/+62
Sorry Jeremy. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-09-27tdb: TDB_INCOMPATIBLE_HASH, to allow safe changing of default hash.Rusty Russell6-6/+23
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: automatically identify Jenkins hash tdbsRusty Russell1-14/+27
If the caller to tdb_open_ex() doesn't specify a hash, and tdb_old_hash doesn't match, try tdb_jenkins_hash. This was Metze's idea: it makes life simpler, especially with the upcoming TDB_INCOMPATIBLE_HASH flag. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-09-27tdb: add Bob Jenkins lookup3 hash as helper hash.Rusty Russell7-18/+447
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(). This version taken from CCAN and modified, which took it from http://www.burtleburtle.net/bob/c/lookup3.c. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2010-09-19pytdb: Fix repr segfault for internal dbKirill Smelkov2-1/+11
The problem was tdb->name is NULL for TDB_INTERNAL databases, and so it was crashing ... #0 0xb76944f3 in strlen () from /lib/i686/cmov/libc.so.6 #1 0x0809862b in PyString_FromFormatV (format=0xb72b6a26 "Tdb('%s')", vargs=0xbfc26a94 "") at ../Objects/stringobject.c:211 #2 0x08098888 in PyString_FromFormat (format=0xb72b6a26 "Tdb('%s')") at ../Objects/stringobject.c:358 #3 0xb72b65f2 in tdb_object_repr (self=0xb759e060) at ./pytdb.c:439 Cc: 597089@bugs.debian.org Signed-off-by: Kirill Smelkov <kirr@mns.spb.ru> Signed-off-by: Jelmer Vernooij <jelmer@samba.org>

Note, unlike tdb_open where flags is `int', tdb_{add,remove}_flags want flags as `unsigned', so instead of "i" I used "I" in PyArg_ParseTuple. Cc: 597386@bugs.debian.org Signed-off-by: Kirill Smelkov <kirr@mns.spb.ru> Signed-off-by: Jelmer Vernooij <jelmer@samba.org>

2010-09-13tdb: put example hashes into header, so we notice incorrect hash_fn.Rusty Russell3-2/+65
This is Stefan Metzmacher <metze@samba.org>'s patch with minor changes: 1) Use the TDB_MAGIC constant so both hashes aren't of strings. 2) Check the hash in tdb_check (paranoia, really). 3) Additional check in the (unlikely!) case where both examples hash to 0. 4) Cosmetic changes to var names and complaint message.

2010-09-13tdb: fix tdb_check() on other-endian tdbs.Rusty Russell1-1/+1

2010-09-13tdb: fix tdb_check() on read-only TDBs to actually work.Rusty Russell1-5/+17
Commit bc1c82ea137 "Fix tdb_check() to work with read-only tdb databases." claimed to do this, but tdb_lockall_read() fails on read-only databases. Also make sure we can still do tdb_check() inside a transaction (weird, but we previously allowed it so don't break the API). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-09-13tdb: make check more robust against recovery failures.Rusty Russell1-5/+36
We can end up with dead areas when we die during transaction commit; tdb_check() fails on such a (valid) database. This is particularly noticable now we no longer truncate on recovery; if the recovery area was at the end of the file we used to remove it that way.

2010-08-14tdb: workaround starvation problem in locking entire database.Rusty Russell4-19/+131
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>

tdb_lockall() uses F_WRLCK internally, which doesn't work on a fd opened with O_RDONLY. Use tdb_lockall_read() instead. Jeremy.

2010-05-05tdb: fix short write logic in tdb_new_databaseRusty Russell3-17/+17
Commit 207a213c/24fed55d purported to fix the problem of signals during tdb_new_database (which could cause a spurious short write, hence a failure). However, the code is wrong: newdb+written is not correct. Fix this by introducing a general tdb_write_all() and using it here and in the tracing code.

2010-04-20tdb: update tdb ABI to use hide_symbols=TrueAndrew Tridgell5-78/+67
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.
