When flushing tables, there were a slight chance that the flush was occuring
between processing of two table map events. Since the tables are opened
one by one, it might result in that the tables were not valid and that sub-
sequent locking of tables would cause the slave to crash.
The problem is solved by opening and locking all tables at once using
simple_open_n_lock_tables(). Also, the patch contain a change to open_tables()
so that pre-locking only takes place when the trg_event_map is not zero, which
was not the case before (this caused the lock to be placed in thd->locked_tables
instead of thd->lock since the assumption was that triggers would be called
later and therefore the tables should be pre-locked).
The REPAIR TABLE ... USE_FRM query silently corrupts data of tables
with old .FRM file version.
The mysql_upgrade client program or the REPAIR TABLE query (without
the USE_FRM clause) can't prevent this trouble, because in the
common case they don't upgrade .FRM file to compatible structure.
1. Evaluation of the REPAIR TABLE ... USE_FRM query has been
modified to reject such tables with the message:
"Failed repairing incompatible .FRM file".
2. REPAIR TABLE query (without USE_FRM clause) evaluation has been
modified to upgrade .FRM files to current version.
3. CHECK TABLE ... FOR UPGRADE query evaluation has been modified
to return error status when .FRM file has incompatible version.
4. mysql_upgrade and mysqlcheck client programs call CHECK TABLE
FOR UPGRADE and REPAIR TABLE queries, so their behaviors have
been changed too to upgrade .FRM files with incompatible
version numbers.
Addresses the following bugs:
Change the fix for Bug#32440 to show bytes instead of kilobytes in
INFORMATION_SCHEMA.TABLES.DATA_FREE.
branches/5.1: Fix bug#29507 TRUNCATE shows to many rows effected
In InnoDB, the row count is only a rough estimate used by SQL
optimization. InnoDB is now return row count 0 for TRUNCATE operation.
branches/5.1: Fix bug#35537 - Innodb doesn't increment handler_update
and handler_delete
Add the calls to ha_statistic_increment() in ha_innobase::delete_row()
and ha_innobase::update_row().
Fix Bug#36169 create innodb compressed table with too large row size crashed
Sometimes it is possible that
row_drop_table_for_mysql(index->table_name, trx, FALSE); is invoked in
row_create_index_for_mysql() when the index object is freed so copy the
table name to a safe place beforehand and use the copy.
Fix Bug#36434 ha_innodb.so is installed in the wrong directory
Change pkglib_LTLIBRARIES with pkgplugin_LTLIBRARIES which has been
forgotten in this commit: http://lists.mysql.com/commits/40206
Enable previously disabled test cases which were tested against
the embedded build. The test cases are modified so that they require
non-embedded build.
The event scheduler was not designed to work in embedded mode. This
patch disables and excludes the event scheduler when the server is
compiled for embedded build.
Problem was that mysql_create_view did not remove all comments characters
when writing to binlog, resulting in parse error of stmt on slave side.
Solution was to use the recreated select clause
and add a generated CHECK OPTION clause if needed.
Temporarily checking in an incorrect test case. Rationale: the impact of
this bug is negligible (it's almost a feature request). We need 5.1 to be
stable, and making a real fix is a bit risky. So the fix is postponed
to 6.0.
The test suite/rpl/t/rpl_innodb_bug28430.test was disabled because of
BUG#32247, but not re-enabled when BUG#32247 was fixed. I've re-enabled
it. The test and result file needed to be updated too.
- Disable the "prefer full scan on clustered primary key over full scan
of any secondary key" rule introduced by BUG#35850.
- Update test results accordingly
(bk trigger: file this for BUG#35850)
The problem is that the patch for Bug 33464 didn't update the
results of the test cases which caused the problem.
Dropping a stored routine also revoke privileges for all users
on the stored routine and errors about missing grants are converted
into warnings. Before Bug 33464 such errors could be incorrectly
returned to the user, which would later trigger a assertion due to
multiple errors being set.
or incorrect.
For better conformance with standard, truncation procedure of CHAR columns
has been changed to ignore truncation of trailing whitespace characters
(note has been removed).
Finally, for columns with non-binary charsets:
1. CHAR(N) columns silently ignore trailing whitespace truncation;
2. VARCHAR and TEXT columns issue Note about truncation.
BLOBs and other columns with BINARY charset are unaffected.
