Heikki Linnakangas cb2d158c58 Fix locking while setting flags in MySerializableXact. ... Even if a flag is modified only by the backend owning the transaction, it's not safe to modify it without a lock. Another backend might be setting or clearing a different flag in the flags field concurrently, and that operation might be lost because setting or clearing a bit in a word is not atomic. Make did-write flag a simple backend-private boolean variable, because it was only set or tested in the owning backend (except when committing a prepared transaction, but it's not worthwhile to optimize for the case of a read-only prepared transaction). This also eliminates the need to add locking where that flag is set. Also, set the did-write flag when doing DDL operations like DROP TABLE or TRUNCATE -- that was missed earlier.		2011-06-10 23:41:10 +03:00
