Make maximum blob size to be 2**32-1, regardless of word size.
Fix failure of timestamp with size of 2**31-1. The method of
rounding up to the nearest even number would overflow.
WL#4165 Prepared statements: validation
WL#4166 Prepared statements: automatic re-prepare
Fixes
Bug#27430 Crash in subquery code when in PS and table DDL changed after PREPARE
Bug#27690 Re-execution of prepared statement after table was replaced with a view crashes
Bug#27420 A combination of PS and view operations cause error + assertion on shutdown
The basic idea of the patch is to keep track of table metadata between
prepared statement prepare and execute. If some table used in the statement
has changed, the prepared statement is re-prepared before execution.
See WL#4165 and WL#4166 contents and comments in the code for details
of the implementation.
Add ChangeLog if it exists
- Removed separate 'normal+rowrepl' test run, not needed any longer
- Removed separate 'rpl' test run, included in main test run already
- Renamed some test "comments", to use similar naming style
- Limited one of the Cluster test runs to 'ndb' and 'rpl_ndb' suites
- Reordered test runs, to be aligned with Windows test runs
mysql.spec.sh:
- No longer including the "Example" storage engine
- Added to configure "--without-ENGINE" if not to compile engine as plugin
Among two claimed artifacts the critical one is in that the Table map of
a query following the failing with a duplicate key error CREATE-SELECT is skipped from
instantionating (and thus binlogging). That leads to sending a "chopped" group of the data
row-events without the table map head to the slave.
The slave can not apply the only data row events.
It's not easy to force the slave to react with an error in such a case (the second complaint
on the bug report), because the lack of a table Rows_log_event::do_apply_event the data row event
handler is a common situation which normally designates the event has to be filtered out
basing on the repliation do/ingore rules decision.
Fixed: table map creating and binlogging is restored via deploying the standard cleanup call in
select_create::abort().
No error is reported if by chance the table map was not been binlogged.
Leaving this out to resolve with considering how to combine the do/ingore rules with the situation
when erronoulsy the Table_map is not written to binlog.
The problem was that symlink.test failed due to debug assertions or
due to errors emitted for wrong statements (in non-debug builds)
if 6.0 version of server was run with --thread-handling=pool-of-threads
option.
The above problems were caused by that on the one hand code mi_create()
which handles case when error is returned relies on my_errno being set
to appropriate non-0 value, but on the other it has not done this
in case when error was emitted due to discovery that share for table
which we are going to create is already present in the list of open
shares. Running server with pool-of-threads option just exposed this
bug since in this scheduler mode my_errno is reset to 0 when connection
(THD) is reattached to the "real" thread.
This fix ensures that code in mi_create() properly sets my_errno in
the case described above.
Since original reason that caused this bug to be exposed in 6.0 tree
might also under very special conditions lead to incorrect behavior
of earlier versions of server (i.e. to errors emitted for wrong
statements) this patch is also being pushed into 5.1 tree.
No test case is present as this code is already covered by a test
case + pushbuild options combination in 6.0.
The problem is that when upgrading the event table, the sql_mode
column was always being added instead of being updated to list new
sql_mode values, causing upgrades of the event which already have
a sql_mode column to not be updated to the new sql_mode values.
The solution is to always add first a stub sql_mode column and
subsequently update the column to the new sql_mode values.
When linking with some external programs, "multiple definition
of `init_time'"
Rename init_time() to my_init_time() to avoid collision with other
libraries (particularly libmng).
