Per fsp0types.h, SDI is on tablespace flags position 14 where MariaDB
stores its pagesize. Flag at position 13, also in MariaDB pagesize
flags, is a MySQL encryption flag.
These are checked only if fsp_flags_is_valid fails, so valid MariaDB
pages sizes don't become errors.
The error message "Cannot reset LSNs in table" was rather specific and
not always true to replaced with more generic error.
ALTER TABLE tbl IMPORT TABLESPACE now reports Unsupported on MySQL
tablespace (rather than index corrupted) along with a server error
message.
MySQL innodb Errors are with with UNSUPPORTED rather than CORRUPTED
to avoid user anxiety.

InnoDB crash recovery can run out of memory before
commit 50324ce624 in
MariaDB Server 10.5.
Let us disable some frequently failing recovery tests
in earlier versions.
Some GNU/Linux distributions ship a zlib that is modified to use
the s390x DFLTCC instruction. That modification would essentially
redefine compressBound(sourceLen) as (sourceLen * 16 + 2308) / 8 + 6.
Let us relax the tests for InnoDB ROW_FORMAT=COMPRESSED to cope with
such a weaker compression guarantee.
create_table_info_t::row_size_is_acceptable(): Remove a bogus debug-only
assertion that would fail to hold for the test innodb_zip.bug36169.
The function page_zip_empty_size() may indeed return 0.
It's misleading to compare and write to user number of columns and fields.
Thus, it would be better to remove that check and let use see a subsequent
error message about missing or mispaced column.
row_import::match_schema(): remove misleading check
The InnoDB DATA DIRECTORY attribute is not implemented via
symbolic links but something similar, *.isl files that contain
the names of data files.
InnoDB failed to ignore the DATA DIRECTORY attribute even though
the server was started with --skip-symbolic-links.
Native ALTER TABLE in InnoDB will retain the DATA DIRECTORY attribute
of the table, no matter if the table will be rebuilt or not.
Generic ALTER TABLE (with ALGORITHM=COPY) as well as TRUNCATE TABLE
will discard the DATA DIRECTORY attribute.
All tests have been run with and without the ./mtr option
--mysqld=--skip-symbolic-links
and some tests that use the InnoDB DATA DIRECTORY attribute
have been adjusted for this.
ALTER TABLE IMPORT doesn't properly handle instant alter metadata.
This patch makes IMPORT read, parse and apply instant alter metadata at the
very beginning of operation. So, cases when source table has some metadata
and destination table doesn't have it now works fine.
DISCARD already removes instant metadata so importing normal table into
instant table worked fine before this patch.
decrypt_decompress(): decrypts and decompresses page if needed
handle_instant_metadata(): this should be the first thing to read source
table. Basically, it applies instant metadata to a destination
dict_table_t object. This is the first thing to read FSP flags so
all possible checks of it were moved to this function.
PageConverter::update_index_page(): it doesn't now read instant metadata.
This logic were moved into handle_instant_metadata()
row_import::match_flags(): this is a first part row_import::match_schema().
As a separate function it's used by handle_instant_metadata().
fil_space_t::is_full_crc32_compressed(): added convenient function
ha_innobase::discard_or_import_tablespace(): do not reload table definition
to read instant metadata because handle_instant_metadata() does it better.
The reverted code was originally added in
4e7ee166a9
ANONYMOUS_VAR: this is a handy thing to use along with make_scope_exit()
full_crc32_import.test shows different results, because no
dict_table_close() and dict_table_open_on_id() happens.
Thus, SHOW CREATE TABLE shows a little bit older table definition.
InnoDB tablespace identifiers and page numbers are 32-bit numbers.
Let us use a 32-bit type for them in innochecksum.
The changes in commit 1918bdf32c
broke the build on 32-bit Windows.
Thanks to Vicențiu Ciorbaru for an initial version of this fixup.
Let us simply refuse an upgrade from earlier versions if the
upgrade procedure was not followed. This simplifies the purge,
commit, and rollback of transactions.
Before upgrading to MariaDB 10.3 or later, a clean shutdown
of the server (with innodb_fast_shutdown=1 or 0) is necessary,
to ensure that any incomplete transactions are rolled back.
The undo log format was changed in MDEV-12288. There is only
one persistent undo log for each transaction.
* be strict in CREATE TABLE, just like in ALTER TABLE, because
CREATE TABLE, just like ALTER TABLE, can be rolled back for any engine
* but don't auto-convert warnings into errors for engine warnings
(handler::create) - this matches ALTER TABLE behavior
* and not when creating a default record, these errors are handled
specially (and replaced with ER_INVALID_DEFAULT)
* always issue a Note when a non-unique key is truncated, because it's
not a Warning that can be converted to an Error. Before this commit
it was a Note for blobs and a Warning for all other data types.
In main.index_merge_myisam we remove the test that was added in
commit a2d24def8c because
it duplicates the test case that was added in
commit 5af12e4635.
Remove CREATE/DROP database.
Remove some unnecessary suppressions, replacements, and
SQL statements.
Populate tables via have_sequence.inc to avoid the creation of
explicit InnoDB record locks in INSERT...SELECT. This will remove
some gaps in AUTO_INCREMENT values.
We should not need anywhere near 32 bits of entropy, so we might
just limit ourselves to a 32-bit random number generator.
Also, it might be cheaper to use exclusive-or, bit shifting and
conditional jumps, instead of multiplication and addition.
We use relaxed atomic operations on the global random number generator
state in order in an attempt to silence any warnings about race conditions.
There is an obvious race condition between the load and store in
ut_rnd_gen(), but we do not think that it matters much that the
state of the random number generator could 'stutter'.
This change seems makes the 'uncompress_ops' nondeterministic
in innodb_zip.cmp_per_index after the restart. It looks like
there is an inherent race condition in the test, because the
table could be opened for InnoDB statistics recalculation
already before innodb_cmp_per_index_enabled was set. We might
end up having uncompress_ops anywhere between 0 and 9, or perhaps
even more. Let us remove that part of the test.
In the test innodb.instant_alter,4k we would be flagging an error
for too large row size. That error was previously only being reported
if the table was being rebuilt. Thus, this merge is fixing a small
omission in MDEV-11369 (instant ADD COLUMN).
Move row size check to early CREATE/ALTER TABLE phase. Stop checking
on table open.
dict_index_add_to_cache(): remove parameter 'strict', stop checking row size
dict_index_t::record_size_info_t: this is a result of row size check operation
create_table_info_t::row_size_is_acceptable(): performs row size check.
Issues error or warning. Writes first overflow field to InnoDB log.
create_table_info_t::create_table(): add row size check
dict_index_t::record_size_info(): this is a refactored version
of dict_index_t::rec_potentially_too_big(). New version doesn't change global
state of a program but return all interesting info. And it's callers who
decide how to handle row size overflow.
dict_index_t::rec_potentially_too_big(): removed
This allows one to run the test suite even if any of the following
options are changed:
- character-set-server
- collation-server
- join-cache-level
- log-basename
- max-allowed-packet
- optimizer-switch
- query-cache-size and query-cache-type
- skip-name-resolve
- table-definition-cache
- table-open-cache
- Some innodb options
etc
Changes:
- Don't print out the value of system variables as one can't depend on
them to being constants.
- Don't set global variables to 'default' as the default may not
be the same as the test was started with if there was an additional
option file. Instead save original value and reset it at end of test.
- Test that depends on the latin1 character set should include
default_charset.inc or set the character set to latin1
- Test that depends on the original optimizer switch, should include
default_optimizer_switch.inc
- Test that depends on the value of a specific system variable should
set it in the test (like optimizer_use_condition_selectivity)
- Split subselect3.test into subselect3.test and subselect3.inc to
make it easier to set and reset system variables.
- Added .opt files for test that required specfic options that could
be changed by external configuration files.
- Fixed result files in rockdsb & tokudb that had not been updated for
a while.
Also, move part of the test back to innodb.innodb_mysql
and another part to a new test innodb.purge.
Last but not least, merge the tests innodb_zip.4k and innodb_zip.8k
to innodb_zip.page_size.
