Problem: When an Incident_log_event contains a bad incident number on disk,
the server crashes with an assertion.
Fix: Don't validate input with assertions. Use errors.
The problem: data file can not be deleted on win because
there is another opened instance of this file.
Data file might be opened twice, on table opening stage and
during write_row execution. We need to close both instances
to satisfy Win.
Added global status variable 'Queries' which represents
total amount of queries executed by server including
statements executed by SPs.
note: It's old behaviour of 'Questions' variable.
Problem was an errornous date that lead to end partition
was before the start, leading to a crash.
Solution was to check greater or equal instead of only
equal between start and end partition.
NOTE: partitioning pruning handles incorrect dates
differently than index lookup, which can give different
results in a partitioned table versus a non partitioned
table for queries having 'bad' dates in the where clause.
If server has not been initialized as a slave (by CHANGE MASTER), then
SHOW SLAVE STATUS will return an empty set, and caused the waiting for
Slave_IO_running or Slave_SQL_running to 'No' fail.
This patch fixed the problem by return immediately if slave is not
initialized in include/wait_for_slave_*_to_stop.inc.
mysqltest command 'shutdown_server' is supposed to shutdown the server
and wait for it to be gone, and kill it when timeout. But because the
arguments passed to my_kill were in the wrong order, 'shutdown_server'
does not wait nor kill the server at all. So after 'shutdown_server',
the server is still running, and the server may still accepting
connections.
Table could be marked dependent because it is
either 1) an inner table of an outer join, or 2) it is a part of
STRAIGHT_JOIN. In case of STRAIGHT_JOIN table->maybe_null should not
be assigned. The fix is to set st_table::maybe_null to 'true' only
for those tables which are used in outer join.
On Winodws FN_DEVCHAR is ':' symbol.
There is a check in mysql_create_table_no_lock() func
on FN_DEVCHAR presence but this code is obsolete and
unnecessary. So the fix is to remove unnecessary code.
The MONTHNAME/DAYNAME functions
returns binary string, so the LOWER/UPPER functions
are not effective on the result of MONTHNAME/DAYNAME call.
Character set of the MONTHNAME/DAYNAME function
result has been changed to connection character set.
Bug#38540 rpl_server_id2 uses show slave status unnecessarily
Slave did not perform any event recorded into the relay log from some
different master when it was started with --replicate-same-server-id.
The reason appeared to be a consequence of BUG#38734 which stopped the
sql thread at its startup time.
The real fixes for the current bug are in the patch for BUG#38734.
This changeset carries only a regression test for the bugs. Bug#38540
gets fixed too by means of eliminating an extra show slave status.
- QUICK_INDEX_MERGE_SELECT deinitializes its rnd_pos() scan when it reaches EOF, but we
need to make the deinitialization in QUICK_INDEX_MERGE_SELECT destructor also. This is because
certain execution strategies can stop scanning without reaching EOF, then then try to do a full
table scan on this table. Failure to deinitialize caused the full scan to use (already empty)
table->sort and produce zero records.
compiled --with-debug, due to bug 39828, "autoinc wraps around when offset and
increment > 1". This change should be reverted when that bug is fixed (and a
a few other minor changes to the test as described in comments).
Static disabled plugins|engines and dynamic plugins which installed but disabled
are not visible in I_S PLUGINS|ENGINES tables because they are not stored into
global plugin array.
The fix: add such plugins|engines to plugin array with PLUGIN_IS_DISABLED status.
I_S.ENGINES 'Transactions', 'XA', 'Savepoints' fields have NULL value in this case.
(server crash)
Altering a table with fulltext index[es] which use
pluggable fulltext parser may cause server crash
in debug builds.
The problem was that ALTER TABLE code wrongly assigned
fulltext parser name.
Also fixed that altering a table with fulltext index[es]
leave stale fulltext parser locks, which prevent
fulltext parsers from being uninstalled after
ALTER TABLE.
