MDEV-19814 Server crash in row_upd_del_mark_clust_rec or Assertion
`update->n_fields < ulint(table->n_cols + table->n_v_cols)' failed in
upd_node_t::make_versioned_helper
This removes the test combination
rocksdb_rpl.mdev12179 'innodb,row,row-write-committed-slave-gtid-optimized'
for which the server failed to start due to the invalid parameter
slave_gtid_info=optimized.
This was broken in 5173e396ff
fts_sync(): Remove the constant parameter has_dict=false.
fts_sync_table(): Remove the constant parameter has_dict=false,
and the redundant parameter unlock_cache = !wait.
Make wait=true the default parameter.
PROBLEM
-------
Index defined on a virtual column whose base column was in a fk
relation was not getting updated. This is because while getting
the updated field information from the update vector of the parent
table we were comparing the column number of the base column (for
virtual column) in child table with the associated column number
in the parent table. There was a mismatch in this column number
because of which this update field information was skipped and
subsequently index was not getting updated.
FIX
The function pointer ut_timer() was only used by the
InnoDB defragmenting thread. Let InnoDB use a single monotonic
high-precision timer, my_interval_timer() [in nanoseconds],
occasionally wrapped by microsecond_interval_timer().
srv_defragment_interval: Change from "timer" units to nanoseconds.
This concludes the InnoDB time function cleanup that was
motivated by MDEV-14154. Only ut_time_ms() will remain for now,
wrapping my_interval_timer().
MDEV-5589 commit set up a policy to skip DROP TEMPORARY TABLE binary logging
in case the target table has not been "CREATEed" in binlog (no CREATE
Query-log-event was logged into the binary log).
It turns out that
1. the rule did not cover non-existing table DROPped with IF-EXISTS clause.
The logged-create knowledge for the non-existing one does not even need
MDEV-5589 patch, and
2. connection close disobeys it to trigger automatic DROP-IF-EXISTS
binlogging.
Either 1 or 2 or even both is/are also responsible for unexpected binlog
records observed in MDEV-17863, actually rendering a referred
@@global.read_only irrelevant as far as the described stored procedure
definition *and* the ROW binlog-format are concerned.
The FTS optimizer thread made a false assumption that time(NULL)
is monotonic. The system clock can be adjusted to the past,
for example if the hardware clock was drifting to the future,
and it was adjusted by NTP.
fts_slot_t::interval_time: Replace with the constant
FTS_OPTIMIZE_INTERVAL_IN_SECS.
fts_slot_t::last_run, fts_slot_t::completed: Clarify the
documentation.
fts_optimize_get_time_limit(): Remove a type cast, and
add a FIXME comment about domain mismatch.
fts_optimize_compact(), fts_optimize_words(): Limit the time
also when the current time has been moved to the past.
fts_optimize_table_bk(): Check for wrap-around.
fts_optimize_how_many(): Check for wrap-around, and remove the
failing assertions.
fts_is_sync_needed(): Remove a redundant call to time(NULL).
lock_t::requested_time: Document what the field is used for.
lock_t::wait_time: Document that the field is only used for
diagnostics and may be garbage if the system time is being adjusted.
srv_slot_t::suspend_time: Document that this is duplicating
trx_lock_t::wait_started.
lock_table_print(), lock_rec_print(): Declare in static scope.
Add a parameter for the current time.
lock_deadlock_check_and_resolve(), lock_deadlock_lock_print(),
lock_deadlock_joining_trx_print():
Add a parameter for the current time.
srv_slot_t::suspend_time, os_aio_slot_t::reservation_time,
sync_cell_t::reservation_time: Explain what could happen
if the system time has is being adjusted.
fts_sync_t::start_time: Document that the field is mostly unused.
Replace ut_usectime() with my_interval_timer(),
which is equivalent, but monotonically counting nanoseconds
instead of counting the microseconds of real time.
os_event_wait_time_low(): Use my_hrtime() instead of ut_usectime().
FIXME: Set a clock attribute on the condition variable that allows
a monotonic clock to be chosen as the time base, so that the wait
is immune to adjustments of the system clock.
Analysis
========
Point in time recovery using mysqlbinlog containing queries
operating on temporary tables results in an error.
While writing the query log event in the binary log, the
thread id used for execution of DROP TABLE and DELETE commands
were incorrect. The thread variable 'thread_specific_used'
is used to determine whether a specific thread id is to used
while executing the statements i.e using 'SET
@@session.pseudo_thread_id'. This variable was not set
correctly for DROP TABLE query and was never set for DELETE
query. The thread id is important for temporary tables
since the tables are session specific. DROP TABLE and DELETE
queries executed using a wrong thread id resulted in errors
while applying the queries generated by mysqlbinlog utility.
Fix
===
Set the 'thread_specific_used' THD variable for DROP TABLE and
DELETE queries.

check_valid_path() uses my_strcspn() that cannot handle invalid characters
properly. This is fixed by a big refactoring in 10.2 (MDEV-6353).
For 5.5, let's simply swap tests, because check_string_char_length()
rejects invalid characters just fine.
Description:- During server startup, the server exits if
the 'mysql.plugin' system table has any rows with empty
value for the field 'name' (plugin name).
