\| *	MDEV-10630 rpl.rpl_mdev6020 fails in buildbot with timeout	Monty	2016-08-22	1	-4/+16
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The issue was that when running with valgrind the wait for master_pos_Wait() was not long enough. This patch also fixes two other failures that could affect rpl_mdev6020: - check_if_conflicting_replication_locks() didn't properly check domains - 'did_mark_start_commit' was after signals to other threads was sent which could get the variable read too early.
\| *	With parallel replication we have had a couple of bugs where DDL's	Monty	2016-08-12	1	-0/+53
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	(like DROP TABLE) has been scheduled before conflicting DDL's (like INSERT) are commited. What makes these bugs hard to detect is that in most cases any wrong schduling are caught by MDL locks. It's only when there are timing issues that the bugs (usually deadlocks) are noticed. This patch adds a DBUG_ASSERT() that detects, in parallel replication, if a DDL is scheduled before any depending DML'S are commited. It does this be checking if there are any conflicting replication locks when the DDL is about to wait for getting it's MDL lock. I also did some minor code cleanups in sql_base.cc to make this code similar to other related code.
\| *	MDEV-9728 - Hard crash in metadata_lock_info	Sergey Vojtovich	2016-06-21	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	metadata_lock_info plugin called MDL_context::find_ticket() to obtain lock duration, which in turn iterates foreign thread private lists. These lists can be updated by owner thread without protection. Fixed by iterating threads (instead of MDL locks and tickets) and obtaining data through APC. Also fixed mdl_iterate_lock() to initialize iterator under prlock protection.

This saves one my_hrtime() call on hot path (when we acquire MDL lock without waiting). When filling I_S.PROCESSLIST use THD::start_utime/THD::utime_after_query instead of THD::start_time. This allows us to save 2 clock_gettime() calls. Overhead change: __clock_gettime 0.13% -> 0.11% (122 -> 76 calls per OLTP RO transaction) my_interval_timer 0.07% -> 0.06% my_hrtime 0.04% -> 0.01%

There is defect report for this: http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#253 Apparently some compilers (e.g. gcc) addressed this defect report, while some (e.g. clang) did not. Added empty default constructor to MDL_scoped_lock and MDL_object_lock classes. Also replaced lf_hash_search_using_hash_value() with lf_hash_search(). The latter will call mdl_key->hash_value() anyway.
