Bug#34424 query_cache_debug.test leads to valgrind warnings Bug#34678 @@debug variable's incremental mode The problem is that the per-thread debugging settings stack wasn't being deallocated before the thread termination, leaking the stack memory. The chosen solution is to push a new state if the current is set to the initial settings and pop it (free) once the thread finishes. dbug/dbug.c: Move dbug parser out of _db_set_ to a separate function and make _db_set_ push a new stack if the corrent one is set to the initial settings. dbug/user.r: Update DBUG_SET description. mysql-test/t/disabled.def: Re-enable test case which triggered the leak. mysys/my_thr_init.c: Pop a pushed state, nop if stack is empty. sql/set_var.cc: Handle incremental debug settings. mysql-test/r/variables_debug.result: Add new test case result for Bug#34678 mysql-test/t/variables_debug.test: Add new test case for Bug#34678 2008-02-26 16:03:59 +01:00			`--source include/have_debug.inc`
