* Fix sequence creation to set the t_xmin of a sequence's tuple toTom Lane2002-01-11
| | | | | | | | | | | | FrozenTransactionId, not the XID of the creating transaction. Without this it's possible for a reference to a long-gone CLOG record to occur, per Christian Meunier's bug report of 10-Jan-02. Worse, the sequence tuple would become invisible to SELECTs after 2 billion transactions. Since the fix is applied during sequence creation it does not help existing databases, unless you drop and recreate every sequence. However, we intend to force initdb for 7.2RC1 anyway, to fix a pg_proc error, so I see no need to do more for this problem.

* Tweak LWLock algorithms so that an awakened waiter for a lock is notTom Lane2002-01-07
| | | | | | | | | | | | | | | granted the lock when awakened; the signal now only means that the lock is potentially available. The waiting process must retry its attempt to get the lock when it gets to run. This allows the lock releasing process to re-acquire the lock later in its timeslice. Since LWLocks are usually held for short periods, it is possible for a process to acquire and release the same lock many times in a timeslice. The old spinlock-based implementation of these locks allowed for that; but the original coding of LWLock would force a process swap for each acquisition if there was any contention. Although this approach reopens the door to process starvation (a waiter might repeatedly fail to get the lock), the odds of that being a big problem seem low, and the performance cost of the previous approach is considerable.
