item when drop table indexes or drop table;
Problem was that table and index statistics is removed from
persistent tables but not from memory cache. Added functions
to remove table and index statistics from memory cache.
The check inserts a DWARF directive to tell stack unwinding that the
bottom of the (co-routine) stack has been reached. Without this, stack
traces may attempt to continue past the bottom of the stack.
The GCC version check was incorrect, and failed to trigger for GCC
version 5.[0123].
Clang warns on this code because it is memsetting over a vtable contained in a
struct in the best_positions array. The diagnostic text is:
mariadb/sql/sql_select.cc:24462:10: error: destination for this 'memset' call is
a pointer to class containing a dynamic class 'Duplicate_weedout_picker'; vtable
pointer will be overwritten [-Werror,-Wdynamic-class-memaccess]
memset(best_positions, 0, sizeof(POSITION) * (table_count + 1));

Problem was that notify_shared_lock() didn't abort an insert delayed thread
if it was in thr_upgrade_write_delay_lock().
ALTER TABLE first takes a weak_mdl_lock, then a thr_lock and then tries to upgrade
the mdl_lock.
Delayed insert thread first takes a mdl lock followed by a
thr_upgrade_write_delay_lock()
This caused insert delay to wait for alter table in thr_lock, while
alter table was waiting for the mdl lock by insert delay.
Fixed by telling mdl to run thr_lock_abort() for the insert delay thread table.
We also set thd->mysys_var->abort to 1 for the delay thread when it's killed
by alter table to ensure it doesn't ever get locked in thr_lock.

Fixed wait condition to wait for InnoDB to actually acquire row locks instead
of waiting for thread to enter "Searching rows for update" state (which happens
earlier).
Also use default wait timeout, 2 seconds can be too few for threads to enter
appropriate state.
Spider:
SunPro only supports array declarations with
constant size. Spider already has a workaround for
that, inside #ifdef _MSC_VER. Enable this code
also for __SUNPRO_CC
Connect:
Don't use anonymous union.
Cast for mmap.
Don't pass gcc-ish -W... options to SunPro
use get_current_user() to distinguish user name without
a hostname and a role name.
move privilege checks inside mysql_show_grants() to remove
duplicate get_current_user() calls
