change SSL methods to be SSLv23 (according to openssl manpage:
"A TLS/SSL connection established with these methods may understand
the SSLv2, SSLv3, TLSv1, TLSv1.1 and TLSv1.2 protocols") from
TLSv1 methods, that go back to the initial SSL implementation
in MySQL in 2001.
OpenSSL default ciphers are different if TLSv1.2 is enabled,
so tests need to take this into account.
two bugs in mysql_config:
1. flags like -Werror=format were not stipped out
2. one-pass s/// command was used that could not remove all matching flags
(e.g. s/ A */ /g cannot remove all A's in " 1 2 A A A A A 4 5 ")
MDEV-6789 segfault in Item_func_from_unixtime::get_date on updating table with virtual columns
* prohibit VALUES in partitioning expression
* prohibit user and system variables in virtual column expressions
* fix Item_func_date_format to cache locale (for %M/%W to return the same as MONTHNAME/DAYNAME)
* fix Item_func_from_unixtime to cache time_zone directly, not THD (and not to crash)
* added tests for other incorrectly allowed (in vcols) functions to see that they don't crash
A "field" could be either an Item_field or
(if loading into a view) an Item_direct_ref that references Item_field.
Also: when iterating fields, use fields of the TABLE_LIST (table or view),
not fields of a TABLE (actual underlying table - might have more columns).
When parsing a field declaration, grab type information from LEX before it's overwritten
by further rules. Pass type information through the parser stack to the rule that needs it.
The test complains that the server failed to disappear upon shutdown /
wait_for_disconnect. Trying to solve the probably race condition by
adding a wait before restart.
Analysis: InnoDB error monitor is responsible to call every second
sync_arr_wake_threads_if_sema_free() to wake up possible hanging
threads if they are missed in mutex_signal_object. This is not
possible if error monitor itself is on mutex/semaphore wait. We
should avoid all unnecessary mutex/semaphore waits on error monitor.
Currently error monitor calls function buf_flush_stat_update()
that calls log_get_lsn() function and there we will try to get
log_sys mutex. Better, solution for error monitor is that in
buf_flush_stat_update() we will try to get lsn with
mutex_enter_nowait() and if we did not get mutex do not update
the stats.
Fix: Use log_get_lsn_nowait() function on buf_flush_stat_update()
function. If returned lsn is 0, we do not update flush stats.
log_get_lsn_nowait() will use mutex_enter_nowait() and if
we get mutex we return a correct lsn if not we return 0.
The test case had a classic mistake: SET DEBUG_SYNC='now SIGNAL xxx'
followed immediately by SET DEBUG_SYNC='RESET'. This makes it
possible for the waiter to miss the signal, if it does not manage
to wake up prior to the RESET.
The test cases had some --replace_result $USER USER. The problem is that the
value of $USER can be anything, depending on the name of the unix account that
runs the test suite. So random parts of the result can be errorneously
replaced, causing test failures.
Fix by making the replacements more specific, so they will match only the
intended stuff regardless of the value of $USER.
The test runs a query in one thread, then in another queries the processlist
and expects to find the first thread in the COM_SLEEP state. The problem is
that the thread signals completion to the client before changing to COM_SLEEP
state, so there is a window where the other thread can see the wrong state.
A previous attempt to fix this was ineffective. It set a DEBUG_SYNC to handle
proper waiting, but unfortunately that DEBUG_SYNC point ended up triggering
already at the end of SET DEBUG_SYNC=xxx, so the wait was ineffective.
Fix it properly now (hopefully) by ensuring that we wait for the DEBUG_SYNC
point to trigger at the end of the SELECT SLEEP(), not just at the end of
SET DEBUG_SYNC=xxx.

(Attempt #2)
- Don't attempt to use BKA for materialized derived tables. The
table is neither filled nor fully opened yet, so attempt to
call handler->multi_range_read_info() causes crash.
