Updated tests: cases with bugs or which cannot be run
with the cursor-protocol were excluded with
"--disable_cursor_protocol"/"--enable_cursor_protocol"
Fix for v.10.5
MDEV-32441 SENT_ROWS shows random wrong values when stored function
is selected.
MDEV-32281 EXAMINED_ROWS is not populated in
information_schema.processlist upon SELECT.
Added ROWS_SENT to information_schema.processlist
This is to have the same information as Percona server (SENT_ROWS)
To ensure that information_schema.processlist has correct values for
sent_rows and examined_rows I introduced two new variables to hold the
total counts so far. This was needed as stored functions and stored
procedures will reset the normal counters to be able to count rows for
each statement individually for slow query log.
Other things:
- Selects with functions shows in processlist the total examined_rows
and sent_rows by the main statement and all functions.
- Stored procedures shows in processlist examined_rows and sent_rows
per stored procedure statement.
- Fixed some double accounting for sent_rows and examined_rows.
- HANDLER operations now also supports send_rows and examined_rows.
- Display sizes for MEMORY_USED, MAX_MEMORY_USED, EXAMINED_ROWS and
QUERY_ID in information_schema.processlist changed to 10 characters.
- EXAMINED_ROWS and SENT_ROWS changed to bigint.
- INSERT RETURNING and DELETE RETURNING now updates SENT_ROWS.
- As thd is always up to date with examined_rows, we do not need
to handle examined row counting for unions or filesort.
- I renamed SORT_INFO::examined_rows to m_examined_rows to ensure that
we don't get bugs in merges that tries to use examined_rows.
- Removed calls of type "thd->set_examined_row_count(0)" as they are
not needed anymore.
- Removed JOIN::join_examined_rows
- Removed not used functions:
THD::set_examined_row_count()
- Made inline some functions that where called for each row.
This patch adds for "--ps-protocol" second execution
of queries "SELECT".
Also in this patch it is added ability to disable/enable
(--disable_ps2_protocol/--enable_ps2_protocol) second
execution for "--ps-prototocol" in testcases.
