7332af49e4 - Renaming variables so that they don't shadow others (After this patch one can compile with -Wshadow and get much fewer warnings)
- Changed ER(ER_...) to ER_THD(thd, ER_...) when thd was known or if there was many calls to current_thd in the same function.
- Changed ER(ER_..) to ER_THD_OR_DEFAULT(current_thd, ER...) in some places where current_thd is not necessary defined.
- Removing calls to current_thd when we have access to thd

Part of this is optimization (not calling current_thd when not needed),
but part is bug fixing for error condition when current_thd is not defined
(For example on startup and end of mysqld)

Notable renames done as otherwise a lot of functions would have to be changed:
- In JOIN structure renamed:
   examined_rows -> join_examined_rows
   record_count -> join_record_count
- In Field, renamed new_field() to make_new_field()

Other things:
- Added DBUG_ASSERT(thd == tmp_thd) in Item_singlerow_subselect() just to be safe.
- Removed old 'tab' prefix in JOIN_TAB::save_explain_data() and use members directly
- Added 'thd' as argument to a few functions to avoid calling current_thd.

* Skip aborting an already aborted thd
* Defer setting OK status in case of CTAS
* Minor cosmetic changes

8f603bcbca MDEV-7952 - clock_gettime() takes 0.24% in OLTP RO
Initialize abs_timeout when it is about to be used. 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%

ff1e0821d1 MDEV-8073 - Build error in sql/mdl.cc on OS X 10.10
C++03 seem to require default constructor for const objects even though they're
fully initialized. 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.

f5bd1d0126 MDEV-6089 - MySQL WL#7305 "Improve MDL scalability by using lock-free hash"
Simplified MDL_object_lock and MDL_scoped_lock dichotomy so that they can be
stored in LF_HASH. This was done by moving out their differences to a
MDL_lock_strategy structure which is referenced from the MDL_lock object by
pointer.

73ebabd2ee MDEV-7299 Assertion `m_status == DA_ERROR || m_status == DA_OK' fails on concurrent execution of DDL, queries from I_S, and KILL QUERY
Fix MDL to report an error when a wait was killed, but preserve
the old documented behavior of GET_LOCK() where killing it is not an error.

Also remove race conditions in main.create_or_replace test

df4dd593f2 MDEV-6247: Merge 10.0-galera to 10.1.
Merged lp:maria/maria-10.0-galera up to revision 3879.

Added a new functions to handler API to forcefully abort_transaction,
producing fake_trx_id, get_checkpoint and set_checkpoint for XA. These
were added for future possiblity to add more storage engines that
could use galera replication.

b123249010 MDEV-5792 - Deadlock between SELECTs from METADATA_LOCK_INFO and another
I_S table

mdl_iterate() helper function (which is used by the plugin to iterate mdl
locks) acquired mutexes in reverse order.

Fixed by iterating MDL locks in two stages:
1. Iterate locks hash under the protection of hash mutex, store all
   lock pointers in a thread local array and increment reference counter
   for the lock.
2. Iterate local array without protection of hash mutex, handle destroyed
   locks.

It somewhat echoes hack in MDL_map_partition::move_from_hash_to_lock_mutex.

e4fde57712 MDEV-5864 - Reduce usage of LOCK_open: TABLE_SHARE::tdc.free_tables
Let TABLE_SHARE::tdc.free_tables, TABLE_SHARE::tdc.all_tables,
TABLE_SHARE::tdc.flushed and corresponding invariants be protected by
per-share TABLE_SHARE::tdc.LOCK_table_share instead of global LOCK_open.

b95c8ce530 MDEV-5675 - Performance: my_hash_sort_bin is called too often
Reduced number of my_hash_sort_bin() calls from 4 to 1 per query.
Reduced number of memory accesses done by my_hash_sort_bin().

Details:
- let MDL subsystem use pre-calculated hash value for hash
  inserts and deletes
- let table cache use pre-calculated MDL hash value
- MDL namespace is excluded from hash value calculation, so that
  hash value can be used by table cache as is
- hash value for MDL is calculated as resulting hash value + MDL
  namespace
- extended hash implementation to accept user defined hash function
