Set a proper type for string literals on ConstantColumn ctor
to fix the regression produced by MCOL-174.
Removed OPTIMIZER_SWITCH_EXISTS_TO_IN b/c MDB produces
unsupported optimization with it and CS couldn't create
ExistsFilter.
in projection list of the queries with GROUP BY and ORDER BY.
Removed support for Item_equal b/c it is an internal format MDB uses
and shouldn't be used outside of MDB's optimizer.
any function in projection looking for either aggregation function or
GROUP BY key column.
MDB doesn't convert Item_equal into corresponding Item_func_eq w/o
OPTIMIZER_SWITCH_COND_PUSHDOWN_FROM_HAVING optimizer flag.
Activation of the flag fixes queries from having test scenario w
equal operator in HAVING, e.g. HAVING c1 = 50.
This happens in external_lock() whilst locking the table.
Fixes LIMIT=1 optimization for EXISTS_SUBS subqueries.
external_lock() contains if condition that gives false positive
for SH + pushed conditions.
external_lock() now resets in_subquery_conversion_threshold
variable that governs IN_INTO_SUBQUERY optimization for
queries run in table mode.
external_lock() now purges dynamicall allocated condInfo for
SH and DH execution path.
Commented out UNION check b/c if condition gives false positives
and silently enables table mode execution for queries w/o
UNION.
This patch:
* Moves config files from /usr/local/mariadb/columnstore/etc to
ENGINE_SYSCONFDIR/columnstore (ENGINE_SYSCONFDIR is /etc by default)
* Sets a define called MCSSYSCONFDIR whic contains the
ENGINE_SYSCONFDIR compile time setting
* Modifies scripts and code to use the new paths
* Removes a whole bunch of files we don't use
This patch:
* Moves ColumnStore my.cnf to /etc/my.cnf.d/columnstore.cnf
* Removes unneeded entries from columnstore.cnf
* Removes some things that used my.cnf and are now dead
* Also removes utils/scenarios
* Modifies things that use extra defaults file to use the standard one
* Makes sure that C++11 standard is used for older CMake versions
With this patch we no longer need to set -DINSTALL_SYSCONF2DIR and
-DINSTALL_SYSCONFDIR when building MariaDB server.
2. Fallback to using sql_select_limit system variable value if an explicit limit is not supplied.
3. Remove checks that did not allow (2^64 - 1) as a valid limit value.
I returned if predicate that guards FE-BE initial connection
block. This predicated had been removed by accident in cb36041
Since we switched to internal ORDER BY FE now reduces the
default limit value to uint64-2 this broke a predicate check
for correlated subqueries. I replaced a predicate with more
reasonable to avoid false positives.
call.
CS doesn't use SH for SELECT..INTO OUTFILE queries.
Clean up gwi::physTableList when processing Storage API request.
SH now explicitly set an execution error in THD::stmt_da.
SH now set queryState in select_next() to mark a begging of the execution.
