- no need to use --skip-ndb in collections files anymore, since long but
more clear logic after recent mtr.pl fixes. ndb tests are never run in MySQL Server
unless explicitly requested
- remove sys_vars.ndb_log_update_as_write_basic.test and sys_vars.ndb_log_updated_only_basic.result since MySQL Server does not have those
options.
- Only sys_vars.have_ndbcluster_basic left since MySQL Server has that variable hardcoded.
btr_lift_page_up() writes wrong page number (different by -1) for upper than father page.
But in almost all of the cases, the father page should be root page, no upper
pages. It is very rare path.
In addition the leaf page should not be lifted unless the father page is root.
Because the branch pages should not become the leaf pages.

main.mysqlbinlog_row_innodb are skipped by mtr
=== Problem ===
The following tests are wrongly placed in main suite and as a
result these are not run with proper binlog format combinations.
Some are always skipped by mtr.
1) mysqlbinlog_row_myisam
2) mysqlbinlog_row_innodb
3) mysqlbinlog_row.test
4) mysqlbinlog_row_trans.test
5) mysqlbinlog-cp932
6) mysqlbinlog2
7) mysqlbinlog_base64
=== Background ===
mtr runs the tests placed in main suite with binlog format=stmt.
Those that need to be tested against binlog format=row or mixed
or more than one binlog format and require only one mysql server
are placed in binlog suite. mtr runs tests in binlog suite with
all three binlog formats(stmt,row and mixed).
=== Fix ===
1) Moved the test listed in problem section above to binlog suite.
2) Added prefix "binlog_" to the name of each test case moved.
Renamed the coresponding result files and option files accordingly.
mysql-test/extra/binlog_tests/mysqlbinlog_row_engine.inc:
include file for mysqlbinlog_row_myisam.test and
mysqlbinlog_row_myisam.test which are being moved to
binlog suite.
mysql-test/suite/binlog/r/binlog_mysqlbinlog-cp932.result:
result file for mysqlbinlog-cp932.test which is being moved to
binlog suite.
mysql-test/suite/binlog/r/binlog_mysqlbinlog2.result:
result file for mysqlbinlog2.test which is being moved to
binlog suite.
mysql-test/suite/binlog/r/binlog_mysqlbinlog_base64.result:
result file for mysqlbinlog_base64.test which is being moved to
binlog suite.
mysql-test/suite/binlog/r/binlog_mysqlbinlog_row.result:
result file for mysqlbinlog_row.test which is being moved to
binlog suite.
mysql-test/suite/binlog/r/binlog_mysqlbinlog_row_innodb.result:
result file for mysqlbinlog_row_innodb.test which is being moved to
binlog suite.
mysql-test/suite/binlog/r/binlog_mysqlbinlog_row_myisam.result:
result file for mysqlbinlog_row_myisam.test which is being moved to
binlog suite.
mysql-test/suite/binlog/r/binlog_mysqlbinlog_row_trans.result:
result file for mysqlbinlog_row_trans.test which is being moved to
binlog suite.
mysql-test/suite/binlog/t/binlog_mysqlbinlog-cp932-master.opt:
option file for mysqlbinlog-cp932.test which is being moved to
binlog suite.
mysql-test/suite/binlog/t/binlog_mysqlbinlog-cp932.test:
the test requires binlog format=stmt or mixed. Since, it was placed in
main suite earlier, it was only run with binlog format=stmt, and hence
this test was never run with binlog format=mixed.
mysql-test/suite/binlog/t/binlog_mysqlbinlog2.test:
the test requires binlog format=stmt or mixed. Since, it was placed in
main suite earlier, it was only run with binlog format=stmt, and hence
this test was never run with binlog format=mixed.
mysql-test/suite/binlog/t/binlog_mysqlbinlog_base64.test:
the test requires binlog format=row. Since, it was placed in main
suite earlier, it was only run with binlog format=stmt, and hence
this test was always skipped by mtr.
mysql-test/suite/binlog/t/binlog_mysqlbinlog_row.test:
the test requires binlog format=row. Since, it was placed in main
suite earlier, it was only run with binlog format=stmt, and hence
this test was always skipped by mtr.
mysql-test/suite/binlog/t/binlog_mysqlbinlog_row_innodb.test:
the test requires binlog format=row. Since, it was placed in main
suite earlier, it was only run with binlog format=stmt, and hence
this test was always skipped by mtr.
mysql-test/suite/binlog/t/binlog_mysqlbinlog_row_myisam.test:
the test requires binlog format=row. Since, it was placed in main
suite earlier, it was only run with binlog format=stmt, and hence
this test was always skipped by mtr.
mysql-test/suite/binlog/t/binlog_mysqlbinlog_row_trans.test:
the test requires binlog format=row. Since, it was placed in main
suite earlier, it was only run with binlog format=stmt, and hence
this test was always skipped by mtr.
Generalized support for auto-updated and/or auto-initialized timestamp
and datetime columns. This patch is a reimplementation of MySQL's
"WL#5874: CURRENT_TIMESTAMP as DEFAULT for DATETIME columns". In order to
ease future merges, this implementation reused few function and variable
names from MySQL's patch, however the implementation is quite different.
TODO:
The only unresolved problem in this patch is the semantics of LOAD DATA for
TIMESTAMP and DATETIME columns in the cases when there are missing or NULL
columns. I couldn't fully comprehend the logic behind MySQL's behavior and
its relationship with their own documentation, so I left the results to be
more consistent with all other LOAD cases.
The problematic test cases can be seen by running the test file function_defaults,
and observing the test case differences. Those were left on purpose for discussion.
SECONDARY INDEX UPDATES MAKE CONSISTENT READS DO O(N^2) UNDO PAGE
LOOKUPS (honoring kill query while accessing sec_index)
If secondary index is being used for select query evaluation and this
query is operating with consistent read snapshot it might take good time for
secondary index to return back control to mysql as MVCC would kick in.
If user issues "kill query <id>" while query is actively accessing
secondary index it will not be honored as there is no hook to check
for this condition. Added hook for this check.
-----
Parallely secondary index taking too long to evaluate for consistent
read snapshot case is being examined for performance improvement. WL#6540.

CONSISTENT SNAPSHOT OPTION
A transaction is started with a consistent snapshot. After
the transaction is started new indexes are added to the
table. Now when we issue an update statement, the optimizer
chooses an index. When the index scan is being initialized
via ha_innobase::change_active_index(), InnoDB reports
the error code HA_ERR_TABLE_DEF_CHANGED, with message
stating that "insufficient history for index".
This error message is propagated up to the SQL layer. But
the my_error() api is never called. The statement level
diagnostics area is not updated with the correct error
status (it remains in Diagnostics_area::DA_EMPTY).
Hence the following check in the Protocol::end_statement()
fails.
516 case Diagnostics_area::DA_EMPTY:
517 default:
518 DBUG_ASSERT(0);
519 error= send_ok(thd->server_status, 0, 0, 0, NULL);
520 break;
The fix is to backport the fix of bugs 14365043, 11761652
and 11746399.
14365043 PROTOCOL::END_STATEMENT(): ASSERTION `0' FAILED
11761652 HA_RND_INIT() RESULT CODE NOT CHECKED
