* chore(ci): collect asan ubsan and libc++ build with mtr and regression status ignored
The old behavior was to assign TIMESTAMP columns an IS NOT NULL
constraint if list of constraints was empty. Apparently, this particular
invariant was changed in 11.4 and bugfixes' mcol-5480.test started to
fail.
This patch fixes behavioral difference and reenables mcol-5480 test in
11.4.
This is a fix of a problem found by UBSAN. MDB changed default type to
represent a decimal result, C-style cast did not do proper type checking
and this one-liner fixes that. Now we will have an assertion if type
changes again.
* fix(plugin): MCOL-4740: This fixes update rows counter for multi-table update
For UPDATEs involving a single table, the server call to handler::direct_update_rows() is used to correctly set the count for the number of updated rows in the UPDATE statement.
However, for UPDATEs involving multi-tables, the server does not call handler::direct_update_rows(). This patch adds support to correctly report the number of updated rows to the client by setting
multi_update::updated and multi_update::found in handler::rnd_end().
* fix(plugin): MCOL-4740: this is to addres the original patch QA found in the original patch

This fixes discrepance with the server, which assigns DATE type to
last_day()'s result.
Now we also assigns DATE result type and, also, use proper
dataconvert::Day data structure to return date.
Tests agree with InnoDB.
Also, this patch includes test for MCOL-5669, to show we fixed it.
The purpose of this changeset is to obtain list of partitions from
SELECT_LEX structure and pass it down to joblist and then to
CrossEngineStep to pass to InnoDB.
* move GROUP_CONCAT/JSON_ARRAYAGG storage to the RowGroup from
the RowAggregation*
* internal data structures (de)serialization
* get rid of a specialized classes for processing JSON_ARRAYAGG
* move the memory accounting to disk-based aggregation classes
* allow aggregation generations to be used for queries with
GROUP_CONCAT/JSON_ARRAYAGG
* Remove the thread id from the error message as it interferes with the mtr
Sometimes server assigns DOUBLE type for arithmetic operations over
DECIMAL arguments. In this rare case width of result was incorrectly
adjusted and it triggered an assertion.
Now width of result gets adjusted only if result type is also DECIMAL.
This patch introduces an internal aggregate operator SELECT_SOME that
is automatically added to columns that are not in GROUP BY. It
"computes" some plausible value of the column (actually, last one
passed).
Along the way it fixes incorrect handling of HAVING being transferred
into WHERE, window function handling and a bit of other inconsistencies.
The most important fix here is the fix of possible buffer overrun in
DATEFORMAT() function. A "%W" format, repeated enough times, would
overflow the 256-bytes buffer for result. Now we use ostringstream to
construct result and we are safe.
Changes in date/time projection functions made me fix difference between
us and server behavior. The new, better behavior is reflected in changes
in tests' results.
Also, there was incorrect logic in TRUNCATE() and ROUND() functions in
computing the decimal "shift."
There were numerous memory leaks in plugin's code and associated code.
During typical run of MTR tests it leaked around 65 megabytes of
objects. As a result they may severely affect long-lived connections.
This patch fixes (almost) all leaks found in the plugin. The exceptions
are two leaks associated with SHOW CREATE TABLE columnstore_table and
getting information of columns of columnstore-handled table. These
should be fixed on the server side and work is on the way.
