tables can cause server to crash!
The bug will be fixed by patch for #34779: "crash in checksum table
on federated tables with blobs containing nulls"
Only a test case commited.
when InnoDB frm file corruption
Problem: mysqlcheck runs 'SHOW FULL TABLE' queries to get table lists.
The query may fail for some reasons (e.g. null .frm file) then
mysqlcheck doesn't process the database tables.
Fix: try to run 'SHOW TABLES' if 'SHOW FULL TABLES' failed.
Reordered include files so that no mess will be left if this test is run without InnoDB
Previously, this test would leave a database named 'federated' in such a case and would
cause tests that examined existing databases to fail.
VARIABLE_VALUE field is decreased to 1024 symbols.
(affected I_S tables: GLOBAL_VARIABLES, SESSION_VARIABLES,
GLOBAL_STATUS, SESSION_STATUS).
The only variable which can be longer than 1024 is
init_connect. The variable will be truncated with warning.
Additional fix:
Added where condition filter which speed up queries which
have where condition with expressions which use VARIABLE_NAME
field.
changed 'charset', 'collation' field length from 64 to MY_CS_NAME_SIZE(32)
in tables:
SCHEMATA, TABLES, COLUMNS, CHARACTER_SETS,
COLLATIONS, COLLATION_CHARACTER_SET_APPLICABILITY
mysql_config did not output -ldl (or equivalent) when needed for --libmysqld-libs,
so its output could be insufficient to build an application using the embedded
server.
LIBDL was already set in configure; it's now propagated all the way into the
relevant mysql_config scripts.
japanese characters.
Fix - removed obsolvete setlocale from my_init.c . In MBCS
environments it caused unwanted character-to-byte translations
in fputc() in client code and wrong output as result.
Innodb monitor could cause a server crash because of invalid access to a
shared variable in a concurrent environment.
This patch adds a guard to protect against crashes but not against
inconsistent values because of performance reasons.
Problem 1: BUG#36625: rpl_redirect doesn't do anything useful. It tests an
obsolete feature that was never fully implemented.
Fix 1: Remove rpl_redirect.
Problem 2: rpl_innodb_bug28430 and rpl_flushlog_loop are disabled despite the
bugs for which they were disabled have been fixed.
Fix 2: Re-enable rpl_innodb_bug28430 and rpl_flushlog_loop.
The convert_constant_item function converts a constant to integer using
field for condition like 'field = a_constant'. In some cases the
convert_constant_item is called for a subquery when outer select is already
being executed, so convert_constant_item saves field's value to prevent its
corruption. For EXPLAIN and at the prepare phase field's value isn't
initialized yet, thus when convert_constant_item tries to restore saved
value it fails assertion.
Now the convert_constant_item doesn't save/restore field's value if it's
haven't been read yet. Outer constant values are always saved.
order by
Problem was that the first index read was unordered,
and the next was ordered, resulting in use of
uninitialized data.
Solution was to use the correct variable to see if
the 'next' call should be ordered or not.
Bug#39848 events_bugs fails sporadically on pushbuild
(missing rows in table event_log)
Details: Reimplement the subtest for BUG 28924
- check if the number of rows within the table
event_log changes but don't print rows
because the number varies depending on
load on testing box
- shift DROP USER befor DROP EVENT
= Subtest fits again to old bug
- remove no more needed comments + variables
Bug#39863 events_bugs fails sporadically on pushbuild
(extra processes in I_S.PROCESSLIST)
Details: Abort with appropriate message to the protocol if
release_lock() does not has the intended effect.
This cannot prevent problems caused by the probably
buggy release_lock() but it reveals if we had a
problem in this area.
Bug#39978 main.events_bugs does not clean up
Detail: Restore global.event_scheduler = ON at end of test
Bug#39569 events_bugs fails sporadically on pushbuild
(should have failed with errno 1539)
Detail: Set $wait_timeout to 4 instead of 2
- Fix two instabilities (result sets pulled from processlist in
subtest for bug 16407) which were found during tests with high
parallel I/O load
- Minor improvements of formatting
Details:
- Add comments
- Remove tabs and trailing blanks
- Add line breaks for better readability
