In MySQL 5.6, QUICK_SELECT_DESC calls handler->set_end_range() to
inform the storage engine about the bounds of the range being scanned.
MariaDB doesn't have that (handler::set_end_range call was back-ported
but it is not called from QUICK_SELECT_DESC).
Instead, it got prepare_*scan() methods from TokuDB.
Implement these methods so that MyRocks has information about the range
end.
- rocksdb.tmpdir works (however @@rocksdb_tmpdir has no effect yet!)
- trx_info_rpl is only run in RBR mode
- type_char_indexes_collation now works
= take into account that characters with the same weight can have
any order after sorting (and they do in MariaDB)
= MariaDB doesn't use index-only for extended keys that have partially-
covered columns.
- Fix include paths, add suite.opt
- Add a test for @@rocksdb_supported_compression_types
Now all tests pass, except rocksdb_sysvars.rocksdb_rpl_skip_tx_api_basic
The 'combinations' system in MTR ignores settings from $testname.cnf,
and tries to run RBR test with binlog_format=mixed.
Fixed by using "source include/have_binlog_format_row.inc" which tells
MTR to only run the test with binlog_format=ROW.
The test still needs its $testname.cnf to include suite/rpl/my.cnf. This
is necessary to setup replication
(Using "source include/master-slave.inc" will have MTR set up replication
for the test, but only as long as the testsuite doesn't have its own
suite/rocksdb/my.cnf. We do have that file (and it doesn't set up
replication), so we need to have $testname.cnf to setup replication).
- port Regex_list_handler from facebook/mysql-5.6/sql/handler.cc
put it into a separate file in storage/rocksdb directory
- Adjust the build process so that the main library is build with
Regex_list_handler (which has dependencies on the server),
while RocksDB tools are built without it.
- Un-comment @@rdb_collation_exceptions handling in ha_rocksdb.cc
- Also adjust rocksdb_set_collation_exception_list() to free the
old variable value and alloc the new one.
- Make ha_rocksdb::check_if_supported_inplace_alter() take into
account the Alter_inplace_info::ALTER_PARTITIONED flag
- Adjust the testcase to work in MariaDB
Failure to do so caused a failure in rocksdb.rocksdb test.
When test_if_cheaper_ordering computes is_covering= ...,
- MySQL calls table->file->primary_key_is_clustered()
- MariaDB calls (table->file->index_flags(nr, 0, 1) &
HA_CLUSTERED_INDEX)
The first produces true, the second used to produce false.
- EXPLAIN result differences are due to MariaDB's MDEV-11172
- Don't print the value of rocksdb_supported_compression_types
to .result file
- The rest is trivial Maria-fication
- EXPLAIN is different
- error message is
- the output order is different, because MySQL knows when to use
ha_partition::handle_unordered_scan_next_partition.
Reading the table data without any ordering happens to produce
MariaDB uses ha_partition::handle_ordered_index_scan for this index
scan (this is a deficiency), which causes it to produce the row with
pk=1 first.
MariaDB uses
- MariaDB produces a warning instead of error when the key
length is too long
- Trivial test results updates
- rocksdb.rocksdb still fails but this commit makes some progress.
rocksdb.lock: LOCK TABLE t1 LOW_PRIORITY WRITE does not produce a
warining in MariaDB
rocksdb.unique_check:
- MariaDB's mtr prints connection actions
- New (but temporary) ER_LOCK_WAIT_TIMEOUT text
rocksdb.allow_pk_no_concurrent_insert:
- Fix path
rocksdb.locking_issues
- Fix path
- The test still fails but for a different reason now
- Introduce @@rocksdb_supported_compression_types read-only variable.
It has a comma-separated list of compiled-in compression algorithms.
- Make rocksdb.compression_zstd test skip itself when ZSTD support
is not compiled in
I've moved it to storage/rocksdb/mysql-test/rocksdb/my.cnf,
but replication tests do not include that file?
Will need to get back to this when getting replication to work
facebook/mysql-5.6 has error messages with extra info, MariaDB doesn't
have extra info:
-ERROR HY000: Lock wait timeout exceeded; try restarting transaction: Timeout on index: test.t1.PRIMARY
+ERROR HY000: Lock wait timeout exceeded; try restarting transaction
This patch updates .result files so that differences do not get in the
way; if we decide to use new error message text in MariaDB, this patch
can be applied in reverse.
- Before this, one had to provide appropriate --mysqld=.... options to
mysql-test-run.
- Also moved one option from rocksdb/suite.opt to rocksdb/my.cnf.
MySQL's log entries start with log entries like
YYYY-MM-DD 08:25:04 ...
while MariaDB
YYYY-MM-DD 8:25:04 ...
note that '08' turns into ' 8'.
Made grep pattern to account for this.
- Make the same changes as in the previous cset and in
a cset changing rocksdb.col_opt_null a few csets before.
- MySQL 5.6.11 has fixes for Bug #68472, Bug #16394472, MariaDB doesn't.
adjust the testcase accordingly.
Make the same changes as with rocksdb.col_opt_null a few csets before:
- MariaDB doesn't provide a default value for non-NULL columns
- Wording in error messages is different
- limits for DECIMAL columns are different
- YEAR(2) is deprecated but still supported
- Also added a --sorted_result for an I_S query.
Based on discussion at maria-developers@:
- Remove 'Support --force-restart "pseudo-argument"'
that was added a few csets before
- Instead, use "source include/restart_mysqld.inc" in the
testcases that need a freshly-started server
The differences are due:
- MariaDB 10.1+ assigns different DEFAULT values
= in some cases, MariaDB's table has no default value, while
MySQL's has '' as default.
= BLOB/TEXT can have a default value.
- MariaDB's MTR runs tests with diffferent timezone (affects result of
FROM_UNIXTIME())
- MySQL has removed YEAR(2). MariaDB produces warning but still creates
the column of this type.
- Different wording in warning/error messages.
