* no automatic --loose-skip-innodb added by mtr based on the test name.
instead loose-skip-innodb is now in the default_mysqld.cnf
* have_innodb_plugin.inc is changed to give a verbose "skip" message
(instead of "require: true")
* My::Suite class. It's support in mtr, and everywhere
* support for suite.pm
* when sorting tests, take combinations into account
* support for SUITENAME_COMBINATIONS
* no special treatment for innodb_plugin in mtr_cases.pm
* two special pre-created config groups: ENV and OPT
* allow option names to start from #
* allow magic option to have an argument
* remove dead code
* fix @-substitution to works as expected
* new processes take the value of $opt_verbose automatically, no need to pass it to a constructor
* innodb_plugin suite uses suite.pm and combinations file to test as much as possible
(innodb plugin, xtradb plugin, xtradb static - whatever available)
* besides test-master.opt and test-slave.opt a test.opt file is also
loaded, both for master and slave
* .opt files for all included files are loaded too
* progress report in the xterm titlebar
concurrent I_S query
There were two problem:
1) MYSQL_LOCK_IGNORE_FLUSH also ignored name locks
2) there was a race between abort_and_upgrade_locks and
alter_close_tables
(i.e. remove_table_from_cache and
close_data_files_and_morph_locks)
Which allowed the table to be opened with MYSQL_LOCK_IGNORE_FLUSH flag
resulting in renaming a partition that was already in use,
which could cause the table to be unusable.
Solution was to not allow IGNORE_FLUSH to skip waiting for
a named locked table.
And to not release the LOCK_open mutex between the
calls to remove_table_from_cache and
close_data_files_and_morph_locks by merging the functions
abort_and_upgrade_locks and alter_close_tables.
mysql-test/suite/parts/r/partition_debug_sync_innodb.result:
Bug#50561: ALTER PARTITIONS does not have adequate lock, breaks with
concurrent I_S query
Added test result
mysql-test/suite/parts/t/partition_debug_sync_innodb-master.opt:
Bug#50561: ALTER PARTITIONS does not have adequate lock, breaks with
concurrent I_S query
Added test option
mysql-test/suite/parts/t/partition_debug_sync_innodb.test:
Bug#50561: ALTER PARTITIONS does not have adequate lock, breaks with
concurrent I_S query
Added test file
sql/authors.h:
Bug#50561: ALTER PARTITIONS does not have adequate lock, breaks with
concurrent I_S query
Time to be acknowledged :)
sql/ha_partition.cc:
Bug#50561: ALTER PARTITIONS does not have adequate lock, breaks with
concurrent I_S query
Added DEBUG_SYNC for deterministic testing
sql/mysql_priv.h:
Bug#50561: ALTER PARTITIONS does not have adequate lock, breaks with
concurrent I_S query
Renamed function since merging alter_close_tables into
abort_and_upgrade_lock.
sql/sql_base.cc:
Bug#50561: ALTER PARTITIONS does not have adequate lock, breaks with
concurrent I_S query
Changed MYSQL_LOCK_IGNORE_FLUSH to not ignore name locks
(open_placeholder).
Merged alter_close_tables into abort_and_upgrade_locks
(and added _and_close_table to the name)
to not release LOCK_open between remove_table_from_cache
and close_data_files_and_morph_locks.
Added DEBUG_SYNC for deterministic testing.
sql/sql_partition.cc:
Bug#50561: ALTER PARTITIONS does not have adequate lock, breaks with
concurrent I_S query
Removed alter_close_tables, (merged it into
abort_and_upgrad_lock) so that LOCK_open never is released
between remove_table_from_cache and
close_data_files_and_morph_locks.
sql/sql_show.cc:
Bug#50561: ALTER PARTITIONS does not have adequate lock, breaks with
concurrent I_S query
Added DEBUG_SYNC for deterministic testing
