e4bddc1fab Close database opened by tester.tcl when it is sourced in all.test. Because test scripts are now run in slave interpreters, this connection was not being closed by the first script run as it was previously.

40ad9d2870 If an error (OOM or SQLITE_FULL error) occurs while executing an SQL statement and a statement-transaction is automatically rolled back as a result, if a second error occurs during the statement rollback do a full transaction rollback instead. Otherwise the client can be left with an inconsistent cache.

10ec894c3a If an error occurs while writing frames to the log to commit a transaction, do not mark the pages as clean in the cache. Otherwise, the subsequent rollback does not roll them back (leaving the client to continue with a cache that makes it appear that the transaction was committed - inconsistent with the database on disk).

8b3cf82ddf The shared-memory used by WAL on linux now really is shared memory in /dev/shm.
