2010-08-14	tdb: workaround starvation problem in locking entire database.	Rusty Russell	1	-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>
2010-03-26	tdb: Add a non-blocking version of tdb_transaction_start	Volker Lendecke	1	-1/+1

2010-02-06	tdb: raise version to 1.2.1	Simo Sorce	1	-1/+1
	after recent fixes we need to raise the version to 1.2.1 so that we can require also the right patched version.
2009-12-21	tdb: Also build and install tdb manpages from standalone tdb.	Jelmer Vernooij	1	-0/+7

2009-11-20	tdb: change version to 1.2.0 after adding TDB_*ALLOW_NESTING	Stefan Metzmacher	1	-1/+1
	metze
2009-10-22	lib/tdb: add tdb_check()	Rusty Russell	1	-1/+1
	ctdb wants a quick way to detect corrupt tdbs; particularly, tdbs with loops in their hash chains. tdb_check() provides this. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-09-19	tdb: increase minor version	Andrew Tridgell	1	-1/+1
	we depend on reads in transactions for s4 replication
2009-06-17	tdb: Fix help string in configure flag to enable Python bindings.	Jelmer Vernooij	1	-1/+1

2009-06-15	Add exports file and abi checker for tdb	Simo Sorce	1	-1/+2
	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
2009-06-15	Add option to --disable-python on build	Simo Sorce	1	-0/+9

2009-03-31	up the version to 1.1.4 with the addition of	Andrew Tridgell	1	-1/+1
	tdb_transaction_prepare_commit()
2008-09-29	lib/tdb: increase the version number after some critial changes	Stefan Metzmacher	1	-1/+1
	The tdb_transaction/traverse interaction fixes are critical. metze
2008-09-19	Add shared-build target to tdb.	Simo Sorce	1	-0/+4
	Useful to build multiple standalone libraries that depend on each other without having to install them to the final install dir during the build.
2008-09-17	Move common libraries from root to lib/.	Jelmer Vernooij	1	-0/+30
