    • Revision #2502.513.74 [merge] Mon 2012-03-05 22:33:46 -0800
      • Merge.
      • Revision #2502.541.1 Mon 2012-03-05 20:32:28 -0800
        • Fixed Bug #946055.
        • The function create_hj_key_for_table() that builds the descriptor of the hash join key to access a table of a materialized subquery must ignore any equi-join predicate depending on the tables not belonging to the subquery.
    • Revision #2502.513.73 [merge] Mon 2012-03-05 22:00:24 +0200
      • Automatic merge
      • Revision #2502.540.2 Mon 2012-03-05 21:59:00 +0200
        • Ensure that we mark all processed tables as 'properly closed'.
        • This is needed as last log entry may be a DDL that is not processed and then a table may be left in 'not properly closed state' even if information is correct in it.
      • Revision #2502.540.1 Tue 2012-02-28 23:18:52 +0200
        • Fixed Bug #925377 "Querying myisam table metadata while 'alter table..enable keys' is running may corrupt the table"
        • Fixed wrong mutex order bug in Aria when flush_log_for_bitmap() was called when table is not yet marked for change.
    • Revision #2502.513.72 Mon 2012-03-05 15:48:12 +0200
      • Fix for Bug #944504
      • Problem is that subquery execution can't be called during prepare/optimize phase.
      • Also small fix for subquery test suite.
    • Revision #2502.513.71 Sun 2012-03-04 22:38:17 -0800
      • Fixed Bug #944782.
      • This bug in the function JOIN::drop_unused_derived_keys() could leave the internal structures for a materialized derived table in an inconsistent state. This led to a not quite correct EXPLAIN output when no additional key had been created to access the table. It also may lead to more serious consequences: so, the test case added with this fix caused a crash in mariadb-5.5.20.
  • Revision #3314 Mon 2012-03-05 21:55:25 +0100
    • compilation warning: unused variable

        • Fixed Bug #923236.
        • When working on MWL#247 I forgot to adjust the function create_hj_key_for_table() that created a key definition for hash join keys. The modified function must set the values of the fields ext_key_parts, ext_key_flags, ext_key_part_map added to the key definition structure in MWL#247.
      • Revision #2502.539.2 Tue 2012-01-24 23:34:02 -0800
        • Fixed LP bug #921167.
        • The fields ext_key_flags and ext_key_part_map must be initialized for any key, even for a MyISAM key that never is considered by the optimizer as one extended by hidden components.
      • Revision #2502.539.1 [merge] Tue 2012-01-24 21:12:02 -0800

          • Fixed Bug #914560.
          • The patch for MWL#247 forgot to initialize the TABLE::ext_key_parts and TABLE::ext_key_flags of the temporary tables by a query. This could cause crashes for queries the execution of which needed creation of temporary tables.

          • Slightly corrected the implementation of the function ha_innobase::read_time().
          • Changed the implementation of handler::keyread_time to make the cost of single key index only look-ups dependent on the key entry length.
          • Corrected the index of the last possible components of an extended key in the function best_access_path().
        • Revision #2502.538.1 [merge] Sat 2011-12-31 03:36:20 -0800

      • This bug appeared after the patch for bug 939009 that in the function merge_key_fields forgot to reset a proper value for the val field in the result of the merge operation of the key field created for a regular key access and the key field created to look for a NULL key.
      • Adjusted the results of the test case for bug 939009 that actually were incorrect.
    • Revision #2502.513.69 Tue 2012-02-28 15:41:55 +0100

          • The issue was that Aria allowed too long keys to be created (so that the internal buffer was not big enough to hold the whole key).
          • Key lengths is now limited to HA_MAX_KEY_LENGTH (1000), as for MyISAM.
          • Fixed failure in "_ma_apply_redo_index: Assertion `new_page_length == 0", as found by buildbot.

      • Revision #2502.533.1 Fri 2012-02-24 16:50:22 -0800
        • Fixed Bug #939009.
        • The result of materialization of the right part of an IN subquery predicate is placed into a temporary table. Each row of the materialized table is distinct. A unique key over all fields of the temporary table is defined and created. It allows to perform key look-ups into the table. The table created for a materialized subquery can be accessed by key as any other table. The function best_access-path search for the best access to join a table to a given partial join. With some where conditions this function considers a possibility of a ref_or_null access. If such access employs the unique key on the temporary table then when estimating the cost this access the function tries to use the array rec_per_key. Yet, such array is not built for this unique key. This causes a crash of the server.
        • Rows returned by the subquery that contain nulls don't have to be placed into temporary table, as they cannot be match any row produced by the left part of the subquery predicate. So all fields of the temporary table can be defined as non-nullable. In this case any ref_or_null access to the temporary table does not make any sense and it does not make sense to estimate such an access.
        • The fix makes sure that the temporary table for a materialized IN subquery is defined with columns that are all non-nullable. The also ensures that any row with nulls returned by the subquery is not placed into the temporary table.

      • Allow for faster creation of threads in corner cases where pool would be overloaded with long non-yielding queries.
      • To allow it, change minimum of thread_pool_stall_limit to be 10 milliseconds.
      • Also introduce a new parameter to oversubscribe a group . Number of threads running in parallel would be higher than it normally should, leading to thrashing, but it may improving preemptiveness, which is useful for the described corner case.

    • Revision #3253.1.2 Wed 2012-02-22 11:44:53 +0100
    • Fix MWL#192 build error: Remove SSL special case for embedded server.
    • VIO has SSL in embedded server anyway, so we do not win anything by excluding it.
    • This was actually already done in this changeset:
      • revision-id: kostja@sun.com-20100413150445-8x23keoxdiufgq76
      • "... Also, he removed the (probable) bug of embedded server never using SSL-dependent functions..."
    • But was apparenly lost by a mis-merge of WL#5030.
    • Revision #3253.1.1 [merge] Tue 2012-02-21 22:15:44 +0100
      • Merge MWL#192: Non-blocking client library, into MariaDB 5.5.
      • Revision #2502.531.5 Mon 2012-01-30 13:45:58 +0100
        • MWL#192: Fix problem when we first enable MYSQL_OPT_NONBLOCK, then connect in normal blocking style, then later do a non-blocking operation.
        • In this case, the vio->async_context was not set up correctly, so that non-blocking operation was not properly handled.
      • Revision #2502.531.4 Sun 2012-01-08 10:13:39 +0100
        • Fix non-ssl build.
      • Revision #2502.531.3 Sat 2012-01-07 23:20:08 +0100
        • fix typo.
      • Revision #2502.531.2 Fri 2012-01-06 12:43:18 +0100
        • MWL#192: non-blocking client API, after-review fixes.
        • Main change is that non-blocking operation is now an option that must be explicitly enabled with mysql_option(mysql, MYSQL_OPT_NONBLOCK, ...) before any non-blocing operation can be used.
        • Also the CLIENT_REMEMBER_OPTIONS flag is now always enabled and thus effectively ignored (it was not really useful anyway, and this simplifies things when non-blocking mysql_real_connect() fails).
      • Revision #2502.531.1 Tue 2011-09-20 12:49:25 +0200
        • MWL#192: Non-blocking client API for libmysqlclient.
        • All client functions that can block on I/O have alternate _start() and _cont() versions that do not block but return control back to the application, which can then issue I/O wait in its own fashion and later call back into the library to continue the operation.
        • Works behind the scenes by spawning a co-routine/fiber to run the blocking operation and suspend it while waiting for I/O. This co-routine/fiber use is invisible to applications.
        • For i368/x86_64 on GCC, uses very fast assembler co-routine support. On Windows uses native Win32 Fibers. Falls back to POSIX ucontext on other platforms. Assembler routines for more platforms are relatively easy to add by extending mysys/my_context.c, eg. similar to the Lua lcoco library.
        • For testing, mysqltest and mysql_client_test are extended with the option --non-blocking-api. This causes the programs to use the non-blocking API for database access. mysql-test-run.pl has a similar option --non-blocking-api that uses this, as well as additional testcases.
        • An example program tests/async_queries.c is included that uses the new non-blocking API with libevent to show how, in a single-threaded program, to issue many queries in parallel against a database.
  • Revision #3280 Sat 2012-02-25 16:13:24 +0100
    • make the test result independent from sizeof(void*)
