    • Revision #3427.1.51 Wed 2013-01-23 16:20:39 +0100

      • cleanup: * don't use 'myf flags', when 'my_bool is_thread_specific' is meant * call set_malloc_size_cb() for embedded too * warn in safemalloc if the memory is freed by a wrong thread

    • Revision #3427.1.50 Wed 2013-01-23 16:19:37 +0100

      • cleanup: * remove unused mysql_option * don't allocate 5GB of memory in the mtr tests * restore the behavior in dynamic_column_offset_byte(), put the ifdef correctly * prefer attribute((unused)) to #ifdef * prefer UNINIT_VAR to LINT_INIT * make most Warning_info users blissfully unaware of the postponed initialization * use my_offsetof instead of offsetof where the compiler thinks the latter is incorrect

      • cleanup: remove unused init_dynamic_array and init_dynamic_array2 symbols, as only my_init_dynamic_array and my_init_dynamic_array2 are used everywhere. fix ha_cassandra to compile.

    • Revision #3427.1.48 Wed 2013-01-23 16:18:09 +0100

      • cleanup: use MYF() for mysys flags

    • Revision #3427.1.47 Wed 2013-01-23 16:16:14 +0100

      • MDEV-4011 Added per thread memory counting and usage Base code and idea from a patch from by plinux at Taobao.

      • The idea is that we mark all memory that are thread specific with MY_THREAD_SPECIFIC. Memory counting is done per thread in the my_malloc_size_cb_func callback function from my_malloc(). There are plenty of new asserts to ensure that for a debug server the counting is correct.

      • Information_schema.processlist gets two new columns: MEMORY_USED and EXAMINED_ROWS.

        • The later is there mainly to show how query is progressing.

      • The following changes in interfaces was needed to get this to work:

        • init_alloc_root() amd init_sql_alloc() has extra option so that one can mark memory with MY_THREAD_SPECIFIC

        • One now have to use alloc_root_set_min_malloc() to set min memory to be allocated by alloc_root()

        • my_init_dynamic_array() has extra option so that one can mark memory with MY_THREAD_SPECIFIC

        • my_net_init() has extra option so that one can mark memory with MY_THREAD_SPECIFIC

        • Added flag for hash_init() so that one can mark hash table to be thread specific.

        • Added flags to init_tree() so that one can mark tree to be thread specific.

        • Removed with_delete option to init_tree(). Now one should instead use MY_TREE_WITH_DELETE_FLAG.

        • Added flag to Warning_info::Warning_info() if the structure should be fully initialized.

        • String elements can now be marked as thread specific.

        • Internal HEAP tables are now marking it's memory as MY_THREAD_SPECIFIC.

        • Changed type of myf from int to ulong, as this is always a set of bit flags.

      • Other things:

        • Removed calls to net_end() and thd

        • cleanup() as these are now done in THD()

        • We now also show EXAMINED_ROWS in SHOW PROCESSLIST

        • Added new variable 'memory_used'

        • Fixed bug where kill_threads_for_user() was using the wrong mem_root to allocate memory.

        • Removed calls to the obsoleted function init_dynamic_array()

        • Use set_current_thd() instead of my_pthread_setspecific_ptr(THR_THD,...)

    • Revision #3427.1.46 Wed 2013-01-23 15:52:59 +0100

      • MDEV-3931 Cassandra SE packaging

      • Added autodetection for thrift library and includes Added Cassandra Storage Engine rpm

      • Fix test failure when $vardir does not allow executing programs.

        • Don't connect right away in ha_cassandra::open. If we do this, it becomes impossible to do SHOW CREATE TABLE when the server is not present.

        • Note: CREATE TABLE still requires that connection is present, as it needs to check whether the specified DDL can be used with Cassandra. We could delay that check also, but then one would not be able to find out about errors in table DDL until they do a SELECT.

    • Revision #3413.25.18 Wed 2012-08-29 11:05:46 +0400

      • Cassandra SE: Timestamp data type support.

    • Revision #3413.25.17 Wed 2012-08-29 10:05:21 +0400

      • Cassandra SE

        • Add mapping for INT datatype

        • Primary key column should now be named like CQL's primary key, or 'rowkey' if CF has key_alias.

    • Revision #3413.25.16 Wed 2012-08-29 07:39:22 +0400

      • Cassandra storage engine: add @@rnd_batch_size variable.

    • Revision #3413.25.15 Tue 2012-08-28 20:22:45 +0400

      • MDEV-494, part #1: phantom row for big full-scan selects

        • Full table scan internally uses LIMIT n, and re-starts the scan from the last seen rowkey value. rowkey ranges are inclusive, so we will see the same rowkey again. We should ignore it.

    • Revision #3413.25.14 Tue 2012-08-28 12:53:33 +0400

      • MDEV-480: TRUNCATE TABLE on a Cassandra table does not remove rows

        • Remove HTON_CAN_RECREATE flag, re-create won't delete rows in cassandra.

    • Revision #3413.25.13 Mon 2012-08-27 08:44:58 +0400

      • Cassandra storage engine: BKA support

        • We use HA_MRR_NO_ASSOC ("optimizer_switch=join_cache_hashed") mode

        • Not able to use BKA's buffers yet.

        • There is a variable to control batch size

        • There are status counters.

        • Nedeed to make some fixes in BKA code (to be checked with Igor)

revno: 3383 revision-id: georgi.kodinov@oracle.com-20110818083108-qa3h3ufqu4zne80a committer: Georgi Kodinov Georgi.Kodinov@Oracle.com timestamp: Thu 2011-08-18 11:31:08 +0300 message: . Bug #11766001: 59026: ALLOW MULTIPLE --PLUGIN-LOAD OPTIONS . Implemented support for a new command line option : --plugin-load-add= This option takes the same type of arguments that --plugin-load does and complements --plugin-load (that continues to operate as before) by appending its argument to the list specified by --plugin-load. So --plugin-load can be considered a composite option consisting of resetting the plugin load list and then calling --plugin-load-add to process the argument. Note that the order in which you specify --plugin-load and --plugin-load-add is important : "--plugin-load=x --plugin-load-add=y" will be equivalent to "--plugin-load=x,y" whereas "--plugin-load-add=y --plugin-load=x" will be equivalent to "plugin-load=x". . Incompatible change : the --help --verbose command will no longer print the --plugin-load variable's values (as it doesn't have one). Otherwise both --plugin-load and --plugin-load-add are mentioned in it.
