kroki/tomash@moonlight.intranet	0f0ddc398a	BUG#21051: RESET QUERY CACHE very slow when query_cache_type=0 There were two problems: RESET QUERY CACHE took a long time to complete and other threads were blocked during this time. The patch does three things: 1 fixes a bug with improper use of test-lock-test_again technique. AKA Double-Checked Locking is applicable here only in few places. 2 Somewhat improves performance of RESET QUERY CACHE. Do my_hash_reset() instead of deleting elements one by one. Note however that the slowdown also happens when inserting into sorted list of free blocks, should be rewritten using balanced tree. 3 Makes RESET QUERY CACHE non-blocking. The patch adjusts the locking protocol of the query cache in the following way: it introduces a flag flush_in_progress, which is set when Query_cache::flush_cache() is in progress. This call sets the flag on enter, and then releases the lock. Every other call is able to acquire the lock, but does nothing if flush_in_progress is set (as if the query cache is disabled). The only exception is the concurrent calls to Query_cache::flush_cache(), that are blocked until the flush is over. When leaving Query_cache::flush_cache(), the lock is acquired and the flag is reset, and one thread waiting on Query_cache::flush_cache() (if any) is notified that it may proceed.	20 years ago
monty@mysql.com	54274976e7	Fixed compiler warnings from gcc 4.0.2: - Added empty constructors and virtual destructors to many classes and structs - Removed some usage of the offsetof() macro to instead use C++ class pointers	20 years ago
bell@sanja.is.com.ua	2bcd68973b	Fix for BUG#13549 "Server crash with nested stored procedures if inner routine has more local variables than outer one, and one of its last variables was used as argument to NOT operator". THD::spcont was non-0 when we were parsing stored routine/trigger definition during execution of another stored routine. This confused methods of Item_splocal and forced them use wrong runtime context. Fix ensures that we always have THD::spcont equal to zero during routine/trigger body parsing. This also allows to avoid problems with errors which occur during parsing and SQL exception handlers.	20 years ago
