37de3c2c0b 12956584 followup fix for mysqltest
run_query_stmt() might use disable_xxx vars after calling handle_no_error
  But handle_no_error() hes reverted any ONCE settings
  Fix is to take revert_properties() out of handle_no_error()

32e8085de9 Bug #12956584 - MYSQLTEST: --ENABLE_X OR --DISABLE_X APPLYING ONLY TO NEXT COMMAND/STMT
Followup fixes for --ps-protocol:
  1) Incorrectly set ps_protocol variable instead of ps_protocol_enabled
  2) disable_result_log was tested after calling handle_no_error()
        which would revert a temporary setting.

03b33425e5 many changes to my_getsystime.c:
* my_getsystime() is only an interval timer. Its value can beused for calculating
  time intervals.
* renamed my_getsystime() to my_interval_timer(), to make the semantics
  clearer and let the compiler catch wrong usages of my_getsystime()
  (also future ones, that may come in merges).
* increased its granularity from 100ns to 1ns, old value was for UUID,
  but as UUID can no longer use it directly there is no need to downgrade
  the OS provided value
* fixed the UUID code to anchor the my_interval_timer() on the epoch, as
  required by the UUID standard. That is, this was only needed by UUID,
  and now I've moved it to UUID code from my_getsystime().
* fixed other wrong usages of my_getsystime() - e.g. in calculating
  times for pthread_cond_timedwait. It was buggy and could've caused
  long waits if OS clock would be changed.

Fixed race condition in event that could cause hang when stopping event scheduler with SET GLOBAL event_scheduler=OFF 

client/mysqltest.cc:

sql/event_queue.cc:
  Fixed race condition in event that could cause hang when stopping event scheduler with SET GLOBAL event_scheduler=OFF.

  would be missed and we would be stuck in Event_scheduler::stop() forever.

0ff2a182b6 Bug #11766513 - 59641: Prepared XA transaction in system after hard crash
causes future shutdown hang

InnoDB would hang on shutdown if any XA transactions exist in the
system in the PREPARED state. This has been masked by the fact that
MySQL would roll back any PREPARED transaction on shutdown, in the
spirit of Bug #12161 Xa recovery and client disconnection.

[mysql-test-run] do_shutdown_server: Interpret --shutdown_server 0 as
a request to kill the server immediately without initiating a
shutdown procedure.

xid_cache_insert(): Initialize XID_STATE::rm_error in order to avoid a
bogus error message on XA ROLLBACK of a recovered PREPARED transaction.

innobase_commit_by_xid(), innobase_rollback_by_xid(): Free the InnoDB
transaction object after rolling back a PREPARED transaction.

trx_get_trx_by_xid(): Only consider transactions whose
trx->is_prepared flag is set. The MySQL layer seems to prevent
attempts to roll back connected transactions that are in the PREPARED
state from another connection, but it is better to play it safe. The
is_prepared flag was introduced in the InnoDB Plugin.

trx_n_prepared: A new counter, counting the number of InnoDB
transactions in the PREPARED state.

logs_empty_and_mark_files_at_shutdown(): On shutdown, allow
trx_n_prepared transactions to exist in the system.

trx_undo_free_prepared(), trx_free_prepared(): New functions, to free
the memory objects of PREPARED transactions on shutdown. This is not
needed in the built-in InnoDB, because it would collect all allocated
memory on shutdown. The InnoDB Plugin needs this because of
innodb_use_sys_malloc.

trx_sys_close(): Invoke trx_free_prepared() on all remaining
transactions.

e6c45f5e1f - Reduced memory requirements for mysqltest to 1/4.th This also gave a speedup for 5x for some tests.
- Reduced memory usage from safe_mutex.
- Fixed problem with failing tests that could not restart mysqld becasue the port was reserved
- More DBUG information
- Fixed bug where bitmap_set_prefix() wrote over buffer area.
- Initialize n_pages_flushed in xtradb which was used uninitialized.

client/mysqltest.cc:
  Reduced memory usage (400K -> 80 for simple test;  400M -> 70M for some other tests)
  - Smaller dynamic arrays at start
  - Made 'st_connection' significantly smaller by allocation 'mysql' on demand in mysql_init() and storing require_file in a mem_root.
  - Fixed that when one does --debug we get information from safemalloc in the trace
  (Most of changes are changing &connect->mysql to connect->mysql
libmysql/libmysql.c:
  Don't call mysql_thread_end() if my_init() was called outside of mysql_server_init()
  This is needed to get information from my_end() into the DBUG log
mysql-test/README:
  Fixed wrong comment
mysql-test/mysql-test-run.pl:
  Reserv 20 ports / mysql-test-run thread.
  (Needed as some tests uses 9 mysqld servers)

1756d087cd Fix for BUG#59894
"set optimizer_switch to e or d causes invalid memory writes/valgrind warnings":
due to prefix support, the argument "e" was overwritten with its full value
"engine_condition_pushdown", which caused a buffer overrun.
This was wrong usage of find_type(); other wrong usages are fixed here too.
Please start reading with the comment of typelib.c.

client/mysqldump.c:
  A bug: find_type() expects a bitmap as 3rd argument
  (each bit is a flag controlling a behaviour of the function);
  here it was instead passed the length of the string to search!
  That could give random behaviour of find_type()
  depending on the string.
  We rather need to pass a correct flag to find_type().
  The correct flag is FIND_TYPE_BASIC (0).
  Flag 8 is not needed as buff cannot have a comma (see how buff is filled).
  Flag 1 looks like a superfluous restriction.
  Flag 4 is not user-friendly (why use
  --compatible=2 rather than --compatible=mysql40 ?, and
  we probably not commit to "2" always meaning "mysql40"
  until the end of times).
include/mysql.h.pp:
  This isn't a problematic API change as we go from char* to const char*:
  existing code will run unchanged.
include/typelib.h:
  named constants. Not an enum to not significantly change
  the declaration of find_type() which would be an API change
  (typelib.h is included in mysql.h).
mysql-test/r/mysqldump.result:
  correct result (see the two requested modes in SQL_MODE)
mysql-test/suite/sys_vars/t/optimizer_switch_basic.test:
  test for BUG#59894. The second SET used to crash.
mysql-test/t/mysqldump.test:
  we had no test for multiple modes in --compatible, which is
  supported according to --help
mysys/typelib.c:
  Fix for BUG#59894. parse_name() is asked to match "e" with a row
  of the TYPELIB (the TYPELIB lists permitted flags of optimizer_switch;
  and comes from optimizer_switch_names[] of sys_vars.cc).
  find_type() is capable of supporting prefixes, but if it is not
  passed flag 2 in third argument, it will overwrite its first
  argument (the string to search for) with the complete name,
  here overwriting "e" with "engine_condition_pushdown". But
  as this "e" was a buffer allocated in an Item, it was not big
  enough to host the longer name, thus the crash.
  We don't need to know the complete flag's name; the output used
  from find_type() is just the flag's number (== function's return
  code). So we can pass flag 2 to find_type() in parse_name().
  After doing this fix and the other fixes in this patch, all usages
  of find_type() were using flag 2; in most usages the string to search for,
  is not guaranteed to be long enough to host the complete name
  (it is either directly from argv, or from alloc_root/my_malloc
  done in an earlier call).
  Thus, flag 2 is here made implicit: callers need not pass it anymore,
  it is always automatically turned on.
  This allows to eliminate an oddity: parse_name() took a const char**,
  and then removed "const" before calling find_type(), which could
  theoretically modify the pointed data, thus lying on constness.
  Last, constants for find_type() are now named.
sql-common/client.c:
  Two bugs:
  1) The enum was not in sync with the array (due to a bad porting of WL 1054;
  the extra OPT_ values are about options present in 5.1 and deleted in 5.5);
  added a compile_time_assert() to make sure this doesn't happen again
  2) find_type() was writing past the end of opt_arg; as opt_arg was allocated
  with alloc_root() with no extra space, this was an overrun; it could be seen
  when
  ** building with -DWITH_VALGRIND -DHAVE_purify -DEXTRA_DEBUG
  ** making execution go through the faulty code; this faulty
  code is executed only if the client asks to read a configuration
  file like this:
    mysql_options(mysql, MYSQL_READ_DEFAULT_FILE, "/tmp/cnf.cnf");
  so by adding such line to the start of mysql_client_test.c::client_connect(),
  we could see the valgrind warning:

  This is fixed by having find_type() not overwrite anymore.

6ae9810f38 merge of bug 47902 and (null-merge) of bug 57924.
bug#57924 does not occur in 5.5, so I reverted the 5.1 specific
code and used the errors from 5.5 instead in the tests
