Bug#31610 Remove outdated and redundant tests:
partition_02myisam partition_03ndb
Bug#32405 testsuite parts: partition_char_myisam wrong content
and cleanup of testsuite
- remove/correct wrong comments
- remove workarounds for fixed bugs
- replace error numbers with error names
- exclude subtests from execution which fail now because of
new limitations for partitioning functions
- remove code for the no more intended dual use
fast test in regression tests/slow test in testsuite
- analyze and fix problems with partition_char_innodb
- fix problems caused by last change of error numbers
- Introduce error name to error number mapping which makes
maintenance after next error renumbering easier
In BUG#30244 added FOUND_ROWS() as an unsafe function, but that
works only in mixed mode under 5.1. There is a workaround that
can be used in statement-based mode either under 5.0 or 5.1
where the result of FOUND_ROWS() is stored into a user vari-
able and used that way instead. This will replicate correctly
even under statement-based replication, since it will write
a User_var entry to the binary log. For some other cases, the
value has to be passed explicitly.
This patch adds tests to demonstrate that the workarounds docu-
mented for statement-based replication works as advertised, and
does more extensive tests for cases that does not work under sta-
tement-based replication actually work under mixed mode by switch-
ing to row-based replication.
If a stored function that contains a drop temporary table statement
is invoked by a create temporary table of the same name may cause
a server crash. The problem is that when dropping a table no check
is done to ensure that table is not being used by some outer query
(or outer statement), potentially leaving the outer query with a
reference to a stale (freed) table.
The solution is when dropping a temporary table, always check if
the table is being used by some outer statement as a temporary
table can be dropped inside stored procedures.
The check is performed by looking at the TABLE::query_id value for
temporary tables. To simplify this check and to solve a bug related
to handling of temporary tables in prelocked mode, this patch changes
the way in which this member is used to track the fact that table is
used/unused. Now we ensure that TABLE::query_id is zero for unused
temporary tables (which means that all temporary tables which were
used by a statement should be marked as free for reuse after it's
execution has been completed).
rebuild the table.
The problem was that ROW_FORMAT clause in ALTER TABLE did not trigger
table reconstruction.
The fix is to rebuild a table if ROW_FORMAT is specified.
Problem: rpl_stm_mystery22 is unstable.
Reason: At one place, the test case *should* wait until the SQL thread on the
slave receives an error, but instead it waits until the SQL thread stops. The
SQL thread may stop before the error flag is set, so that when the test case
continues to execute, the error flag is not set.
Fix: Introduce the subroutine mysql-test/include/wait_for_slave_sql_error.inc,
which waits until there is an error in the sql thread of the slave.
Re-commit: fixed one logical error and two smaller things noted by Mats.
Fixed the usage of spatial data (and Point in specific) with
non-spatial indexes.
Several problems :
- The length of the Point class was not updated to include the
spatial reference system identifier. Fixed by increasing with 4
bytes.
- The storage length of the spatial columns was not accounting for
the length that is prepended to it. Fixed by treating the
spatial data columns as blobs (and thus increasing the storage
length)
- When creating the key image for comparison in index read wrong
key image was created (the one needed for and r-tree search,
not the one for b-tree/other search). Fixed by treating the
spatial data columns as blobs (and creating the correct kind of
image based on the index type).
Locked rows of the InnoDB storage was silently skipped in the read-committed
isolation level.
QUICK_RANGE_SELECT for unique ranges lacks second (blocking) read
of the record that was read semi-consistently and just skip it.
The handler::read_multi_range_next method has been modified
to retry previous unique range if the previous read was
semi-consistent.
Problem: The "regex" library written by Henry Spencer
does not support tricky character sets like UCS2.
Fix: convert tricky character sets to UTF8 before calling
regex functions.
and for bug #31070: crash during conversion of charsets
Problem: passing a 0 byte length string to some my_mb_wc_XXX()
functions leads to server crash due to improper argument check.
Fix: properly check arguments passed to my_mb_wc_XXX() functions.
MySQL provides what appears to be a non standard extension to the
FOREIGN KEY syntax which let users name (label/tag) a foreign key
to more easily identify a specific foreign key if any problems show
up later during the query parsing or execution. But the foreign key
name was not being properly set to the right key, possible leaving
the foreign key with no name.
of statement breaks binlog.
There were two problems discovered by this bug:
1. Default (current) database is not fixed at the creation time.
That leads to wrong output of DATABASE() function.
2. Database attributes (@@collation_database) are not fixed at
the creation time. That leads to wrong resultset.
Binlog breakage and Query Cache wrong output happened because of
the first problem.
The fix is to remember the current database at the PREPARE-time and
set it each time at EXECUTE.
