* tdb: add Bob Jenkins lookup3 hash as helper hash.Rusty Russell2010-09-271-0/+61
| | | | | | | | | | 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>

* 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>

| | | | | This is not strictly necessary, as the old types would compare equal, but it is neater to use the generic type names
