A big test was written and is committed, which found 3 bugs in total:
- ALTER TABLE PAGE_CHECKSUM=0 sometimes had no effect
- ALTER TABLE ENGINE=MARIA sometimes changed page checksumming in
the table
- SHOW CREATE TABLE and 'maria_chk -dv' disagreed on the presence
of page checksumming.
They are all fixed here. Side-effect is that SHOW CREATE TABLE now
always prints a PAGE_CHECKSUM clause for Maria tables.
mysql-test/mysql-test-run.pl:
allow calling maria_chk and maria_pack in tests
mysql-test/r/maria.result:
PAGE_CHECKSUM=0 is now always printed
mysql-test/t/create.test:
PAGE_CHECKSUM= is now always present in SHOW CREATE TABLE of Maria tables
mysql-test/t/disabled.def:
better bug number
sql/sql_table.cc:
If ALTER TABLE PAGE_CHECKSUM=#, it affects the engine's data (structure
of data pages) so a full table rebuild is needed. We already did
so for ROW_FORMAT=#, following same logic. This fixes disagreements
between SHOW CREATE TABLE and 'maria_chk -dv' regarding the
presence of page checksums after certain ALTER TABLE (as seen
with the attached testcase).
storage/maria/ha_maria.cc:
In ALTER TABLE PAGE_CHECKSUM=0, ha_maria::update_create_info() started
with create_info->page_checksum=HA_CHOICE_NO and wrongly set it
to the table's original setting, which is HA_CHOICE_YES if the table
had page checksums, in which case the ALTER left page checksum
in the table.
The fix for this bug is: only if create_info->page_checksum is
undefined (no clause in the ALTER TABLE, or we are in SHOW CREATE TABLE)
we may set HA_CHOICE_YES.
The second bug in this file was that the code left HA_CHOICE_UNDEF if
the table didn't have page checksums originally, leading ALTER TABLE
ENGINE=MARIA to change the table's page checksum to the value of
maria_page_checksum.
This is fixed by setting create_info->page_checksum to HA_CHOICE_NO
if UNDEF and table does not have page checksum.
The side-effect of this last fix, because ha_maria::update_create_info()
is also called by SHOW CREATE TABLE, is that:
SET GLOBAL maria_page_checksum=0;
CREATE TABLE t(a INT) ENGINE=MARIA;
SHOW CREATE TABLE t;
which used to not show a PAGE_CHECKSUM= clause, now shows PAGE_CHECKSUM=0.
I consider this side-effect good:
- clearer for users: it eliminates the differences between the
above and this:
SET GLOBAL maria_page_checksum=0;
CREATE TABLE t(a INT) ENGINE=MARIA PAGE_CHECKSUM=0;
SHOW CREATE TABLE t;
which already showed PAGE_CHECKSUM=0; difference which is not easy
to explain.
- if using mysqldump to copy from one server to another, it eliminates
the dependency on the value of maria_page_checksum being the same on
original server and new server.
mysql-test/r/maria-page-checksum.result:
Result. If you undo the code fixes and run the test, the new result
file will show bugs at:
