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.
Realized our Config class wouldn't handle tera- (T/t) processing but
no reason it shouldn't. Ex, they want a 1TB cache, they can specify
'1t' as the cache_size.
- Re-added the StorageManager/Enabled key in the default config file.
Thought I had switched all that stuff to only look at DBRootStorageType
but I was wrong.
- Made the unit_tests bin for SM stay in the SM dir
- Collapsed one level of build dirs for SM. For some reason it was
putting test data in storage-manager/storage-manager/testData
- Limited a single read() call to 100MB as a paranoid safety measure.
Normal usage won't read that much at once anyway.
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.
Write and appendtask were breaking the incoming data into 1MB chunks
to call IOC::write/append() with. Keeping the limit for safety,
but bumping it to 100MB.
SH query execution migrated from SH::init() into create_SH().
There is a session variable columnstore_processing_handlers_fallback
that allows to fallback to DH, GBH if SH fails. DH now uses semantic
tree check for unsupported features to allow to fallback to GBH or
storage API.
Fixes GBH related bug when create_GBH() returns a handler for
queries with impossible WHERE/HAVING.
Fixed bug in FromSubquery::transform() where isUnion is set to true.
Enabled RTTI b/c server team enabled it for MDB.
Removed unused code supposed to be used with vtable.
requirement. Added a safety valve; if the journal file is > 100MB, it
will fall back to the previous IO op heavy but mem friendly version.
This also includes a compiler warning fix for smls & smput.
