* tdb: add TDB_MUTEX_LOCKING supportVolker Lendecke2014-05-221-0/+68
| | | | | | | | | | | | | | | | | | | | | | | | This adds optional support for locking based on shared robust mutexes. The caller can use the TDB_MUTEX_LOCKING flag together with TDB_CLEAR_IF_FIRST after verifying with tdb_runtime_check_for_robust_mutexes() that it's supported by the current system. The caller should be aware that using TDB_MUTEX_LOCKING implies some limitations, e.g. it's not possible to have multiple read chainlocks on a given hash chain from multiple processes. Note: that this doesn't make tdb thread safe!

* tdb: workaround starvation problem in locking entire database.Rusty Russell2010-08-141-0/+60
| | | | | | | | | | | | | | | | | | | | | | | 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>
