Bug #31956 auto increment bugs in MySQL Cluster: Changed meaning of ndb_autoincrement_prefetch_sz to specify prefetch between statements, changed default to 1 (with internal prefetch to at least 32 inside a statement), added handling of updates of pk/unique key with auto_increment
Bug #32055 Cluster does not handle auto inc correctly with insert ignore statement
Since bug@20166, which replaced the binlog file name generating to base
on pidfile_name instead of the previous glob_hostname, the binlog file
name suddenly started to be stored solely in the absolute path format,
including a case when --log-bin option meant a relative path.
What's more serious, the path for binlog file can lead unrequestedly
to pid-file directory so that after any proper fix for this bug
there might be similar to the bug report consequences for one who
upgrades from post-fix-bug@20166-pre-fix-bug@28597 to post-fix-bug@28597.
Fixed with preserving`pidfile_name' (intr.by bug@20166) but stripping
off its directory part. This restores the original logics of storing
the names in compatible with --log-bin option format and with the
requirement for --log-bin ralative path to corresond to the data directory.
Side effects for this fix:
effective fixing bug@27070, refining its test;
ensuring no overrun for buff can happen anymore (Bug#31836
insufficient space reserved for the suffix of relay log file name);
bug#31837 --remove_file $MYSQLTEST_VARDIR/tmp/bug14157.sql missed
in rpl_temporary.test;
fixes Bug@28603 Invalid log-bin default location;
bug #26215: mysql command line client should not strip comments
from SQL statements
and
bug #11230: Keeping comments when storing stored procedures
With the introduction of multiline comments support in the command line
client (mysql) in MySQL 4.1, it became impossible to preserve
client-side comments within single SQL statements or stored routines.
This feature was useful for monitoring tools and maintenance.
The patch adds a new option to the command line client
('--enable-comments', '-c') which allows to preserve SQL comments and
send them to the server for single SQL statements, and to keep comments
in the code for stored procedures / functions / triggers.
The patch is a modification of the contributed patch from bug #11230
with the following changes:
- code style changes to conform to the coding guidelines
- changed is_prefix() to my_strnncoll() to detect the DELIMITER
command, since the first one is case-sensitive and not charset-aware
- renamed t/comments-51.* to t/mysql_comments.*
- removed tests for comments in triggers since 5.0 does not have SHOW
CREATE TRIGGER (those tests will be added back in 5.1).
The test cases are only for bug #11230. No automated test case for bug
#26215 is possible due to the test suite deficiencies (though the cases
from the bug report were tested manually).
The HAVING clause is subject to the same rules as the SELECT list
about using aggregated and non-aggregated columns.
But this was not enforced when processing implicit grouping from
using aggregate functions.
Fixed by performing the same checks for HAVING as for SELECT.
Item_in_subselect's only externally callable method is val_bool().
However the nullability in the wrapper class (Item_in_optimizer) is
established by calling the "forbidden" method val_int().
Fixed to use the correct method (val_bool() ) to establish nullability
of Item_in_subselect in Item_in_optimizer.
Fulltext boolean mode phrase search may crash server on platforms
where size of pointer is not equal to size of unsigned integer
(in other words some 64-bit platforms).
The problem was integer overflow.
Affects 4.1 only.
Item_func_inet_ntoa and Item_func_conv inherit 'maybe_null' flag from an
argument, which is wrong.
Both can be NULL with notnull arguments, so that's fixed.
Query_log_event::error_code
A query can perform completely having the local var error of mysql_$query
zero, where $query in insert, update, delete, load,
and be binlogged with error_code e.g KILLED_QUERY while there is no
reason do to so.
That can happen because Query_log_event consults thd->killed flag to
evaluate error_code.
Fixed with implementing a scheme suggested and partly implemented at
time of bug@22725 work-on. error_status is cached immediatly after the
control leaves the main rows-loop and that instance always corresponds
to `error' the local of mysql_$query functions. The cached value
is passed to Query_log_event constructor, not the default thd->killed
which can be changed in between of the caching and the constructing.
There are two problems with ROUND(X, D) on an exact numeric
(DECIMAL, NUMERIC type) field of a table:
1) The implementation of the ROUND function would change the number of decimal
places regardless of the value decided upon in fix_length_and_dec. When the
number of decimal places is not constant, this would cause an inconsistent
state where the number of digits was less than the number of decimal places,
which crashes filesort.
Fixed by not allowing the ROUND operation to add any more decimal places than
was decided in fix_length_and_dec.
2) fix_length_and_dec would allow the number of decimals to be greater than
the maximium configured value for constant values of D. This led to the same
crash as in (1).
Fixed by not allowing the above in fix_length_and_dec.
The fix is a copy of Martin Friebe's suggestion.
added testing for no_appended which will be false if anything,
including the empty string is in result
