1492de8563 Set the default to be mrr=off,mrr_sort_keys=off:
- Set the default
- Adjust the testcases so that 'new' tests are run with optimizations turned on.
- Pull out relevant tests from "irrelevant" tests and run them with optimizations on.
- Run range.test and innodb.test with both mrr=on and mrr=off

c1de6f8b77 Change the default @@optimizer_switch setting from
semijoin=on,firstmatch=on,loosescan=on
to
  semijoin=off,firstmatch=off,loosescan=off
Adjust the testcases:
- Modify subselect*.test and join_cache.test so that all tests
  use the same execution paths as before (i.e. optimizations that
  are being tested are enabled)
- Let all other test files run with the new default settings (i.e.
  with new optimizations disabled)
- Copy subquery testcases from these files into t/subselect_extra.test
  which will run them with new optimizations enabled.

424e9a888d Fixed several errors in Aria discovered by test case for lp:727869 ma_pagecache.c:2103: find_block: Assertion `block->rlocks == 0
- Fixed assert in transaction log handler when aria_check was run on block-record table that was much bigger than expected.
- Fixed warnings about wrong mutex order between bitmap and intern_lock
- Fixed error in bitmap that could cause two rows to use same block for a block record.
- Fixed wrong test that could cause error if last page for a bitmap was used by a blob.
- Fixed several bugs in pagecache for the case where pagecase had very few blocks and there was a lot of threads competing to get the blocks (very unlikely case).


mysql-test/suite/maria/r/maria-recovery3.result:
  Updated results
sql/mysqld.cc:
  Allow mi_check() to send information messages for log file
storage/maria/ma_bitmap.c:
  Fixed problem with wrong mutex order when bitmap was the first page that was flushed out of page cache
  - Fixed by introducing _ma_bitmap_mark_file_changed() that marks file changed without a bitmap lock.
  - Fixed one case in _ma_change_bitmap_page() where we didn't mark the bitmap changed. This could cause to rows to reuse same block if this was the only change to the bitmap.
  - Split _ma_bitmap_get_page_bits() in two parts to not take a bitmap lock when we already have it
  - Fixed bug in _ma_bitmap_set_full_page_bits() that caused an error if last page for a bitmap was used by a blob
storage/maria/ma_check.c:
  Better handling of wrong file length.
  Fixed bug when we tried to write to transaction log when it was not opened (happened when block record file was bigger than expected)
storage/maria/ma_pagecache.c:
  Fixed several bugs in pagecache for the case where pagecase had very few blocks and there was a lot of threads competing to get the blocks:
  - In link_block() mark a block given to another thread with PCBLOCK_REASSIGNED to ensure that no other threads can start re-using the block
    before the thread that requsted a block.
  - In free_block(), don't reset status for a block that is in re-assign by link_block() (we don't want to loose the PCBLOCK_REASSIGNED flag).
  - Added call to wait_for_flush() when we got a new block in find_block() to ensure that we don't use a block that is beeing flushed by another thread.
  - Moved setting of hits_left and last_hit_time in find_block() to where we assign the block.
  
  
  Code cleanup and making code uniform:
  - Changed a lot of KEYCACHE_DBUG_PRINT to use DBUG_PRINT
  - Streamlined all reporting of 'signal' and 'wait' between threads to be identical.
  - Use thread name instead of thread number (for each match against --debug)
  - Added more DBUG_ENTER, DBUG_PRINT and DBUG_ASSERT()
  - Added more comments
storage/myisam/ha_myisam.cc:
  Only print information about that we make a backup if we are really making a backup.
storage/myisam/mi_check.c:
  Inform mysqld that we are creating a backup of the data file (for inclusion in error log).

3e748505de Fix MySQL Bug #21978 : 'flush_time' value set for 1800 sec
This setting is obsolete now. It could makes sense in the past,  situations open file handles 
limit was low. It does not make sense anymore to flush all files every 1.5 hours now, after 2048 
myisam file limit is removed as fix to MySQL bug #24509.

69ffc06610 Fixes BUG#60976 "Crash, valgrind warning and memory leak with partitioned archive tables"
Noted that there was no memory leak, just a lot of used partitioned tables.
Fixed old bug: 'show status' now shows memory usage when compiled with safemalloc.
Added option --flush to mysqlcheck.c to run a 'flush tables' between each check to keep down memory usage.
Changed '--safemalloc' options to mysqld so that one can use --safemalloc and --skip-safemalloc.
Now skip-safemalloc is default (ie, we only do checking of memory overrun during free()) to speed up tests.


client/client_priv.h:
  Added OPT_FLUSH_TABLES
client/mysqlcheck.c:
  Added option --flush to mysqlcheck.c to run a 'flush tables' between each check to keep down memory usage.
mysql-test/mysql-test-run.pl:
  Always run tests with --loose-skip-safemysqld for higher speed
sql/mysqld.cc:
  Changed '--safemalloc' options so that one can use --safemalloc and --skip-safemalloc.
  Now skip-safemalloc is default (ie, we only do checking of memory overrun during free()) to speed up tests
sql/sql_parse.cc:
  Fixed old bug: 'show status' now shows memory usage when compiled with safemalloc.
storage/archive/archive_reader.c:
  Changed all malloc() calls to use my_malloc()/my_free()
  Added checks of malloc() calls.
storage/archive/ha_archive.cc:
  Detect failure if init_archive_reader() and return errno. This fixed assert crash in my_seek().
  Changed all malloc() calls to use my_malloc()/my_free()

2740edcf56 Fixed that mysqld --no-defaults --help --verbose doesn't give a lot of irrelevant error messages.
sql/mysql_priv.h:
  Make opt_help global
sql/mysqld.cc:
  Don't give (double) warnings about lower case file systems if --help is given.
  Don't give warning about non existing data directory if --help is given.
sql/sql_plugin.cc:
  Give a better warning if --help is used and plugin table doesn't exists

3bf08e549a Added two new flags for the optimizer switch:
'derived_merge':
  - if the flag is off then all derived tables are materialized
  - if the flag is on then mergeable derived tables are merged
'derived_with_keys':
  - if the flag is off then no keys are created for derived tables
  - if the flag is on then for any derived table a key to access 
    the derived table may be created.

Now by default both flags are on.
Later the default values for the flags will be off to comply with
the current behaviour of mysql-5.1. 

Uncommented previously commented out test case from parts.partition_repair_myisam
after having added an explicit requirement to materialize the derived
table used in the test case.

sql/field_conv.cc:
  Added test to get optimal copying of identical temporal values.
sql/item.cc:
  Return that item_int is equal if it's positive, even if unsigned flag is different.
  Fixed Item_cache_str::save_in_field() to have identical null check as other similar functions
  Added proper NULL check to Item_cache_int::save_in_field()
sql/item_cmpfunc.cc:
  Don't call convert_constant_item() if there is nothing that is worth converting.
  Simplified test when years should be converted
sql/item_sum.cc:
  Mark cache values in Item_sum_hybrid as not constants to ensure they are not replaced by other cache values in compare_datetime()
sql/item_timefunc.cc:
  Changed sec_to_time() to take a my_decimal argument to ensure we don't loose any sub seconds.
  Added Item_temporal_func::get_time() (This simplifies some things)

  Added Lazy_string_decimal()
sql/mysqld.cc:
  Added my_decimal constants max_seconds_for_time_type, time_second_part_factor
sql/table.cc:

decb9c639a Fixed sql_perror() to return appropriate error messages on Windows,
The error message is now based on GetLastError() rather than errno. 

Background: errno is C runtime specific and in many circumstances 
it is not set, e.g when using Win32 API or socket functions.

03b33425e5 many changes to my_getsystime.c:
* my_getsystime() is only an interval timer. Its value can beused for calculating
  time intervals.
* renamed my_getsystime() to my_interval_timer(), to make the semantics
  clearer and let the compiler catch wrong usages of my_getsystime()
  (also future ones, that may come in merges).
* increased its granularity from 100ns to 1ns, old value was for UUID,
  but as UUID can no longer use it directly there is no need to downgrade
  the OS provided value
* fixed the UUID code to anchor the my_interval_timer() on the epoch, as
  required by the UUID standard. That is, this was only needed by UUID,
  and now I've moved it to UUID code from my_getsystime().
* fixed other wrong usages of my_getsystime() - e.g. in calculating
  times for pthread_cond_timedwait. It was buggy and could've caused
  long waits if OS clock would be changed.

- Auto-merge with 5.3 main.
- Changed the test for LP BUG#719198 so that
  an two more queries were added, and removed a
  query that produces a wrong result due to an
  unrelated problem. The wrong result is submitted
  as a separate bug.

309e016eec Fixes to get more information about random bind failure in pushbuild for windows hosts.
mysql-test/mysql-test-run.pl:
  Set port-open-timeout to 10 to retry binds
sql/mysqld.cc:
  Write error number for bind failure. (perror can't do that on windows as errno dosn't contain error code)

b20efbb119 Fixed test failures with embedded server
mysql-test/mysql-test-run.pl:
  Don't set --log-error when running embedded server as we don't want the mysqltest output into mysqld.1.err
sql/mysqld.cc:
  Allow one to disable --log-error

dcf6b68d08 Bug #11766769: 59959: SMALL VALUES OF --MAX-ALLOWED-PACKET
ARE NOT BEING HONORED

max_allowed_packet works in conjunction with net_buffer_length.
max_allowed_packet is an upper bound of net_buffer_length.
So it doesn't make sense to set the upper limit lower than the value.
Added a warning (using ER_UNKNOWN_ERRROR and a specific message)
when this is done (in the log at startup and when setting either 
max_allowed_packet or the net_buffer_length variables)
Added a test case.
Fixed several tests that broke the above rule.

7de98f2ffb Added --log-basename to mysqld to allow one to set the prefix for all logs with one command
Changed test suite to use --log-basename (to get the code tested)
Added --sync-sys=1 to test suite to speed it up.
Better error messages if something goes wrong with mysql_install_db


mysql-test/Makefile.am:
  Removed not existing directory
mysql-test/lib/My/ConfigFactory.pm:
  Use log-basename
  We had to also set 'log_error' as some test was explicitely using the old name
  Added 'sync-sys=1' to speed up test suite
mysql-test/r/variables-notembedded.result:
  Updated test results (variable relay_log is now set)
mysql-test/suite/binlog/t/binlog_delete_and_flush_index-master.opt:
  Force specific names for some log files.
mysql-test/suite/binlog/t/binlog_index-master.opt:
  Force specific names for some log files.
mysql-test/suite/binlog/t/binlog_stm_unsafe_warning-master.opt:
  Force specific names for some log files.
mysql-test/suite/binlog/t/binlog_stm_unsafe_warning.test:
  Better error message if something goes wrong
mysql-test/suite/rpl/r/rpl_flushlog_loop.result:
  Updated results
mysql-test/suite/rpl/rpl_1slave_base.cnf:
  Use --log-basename
scripts/mysql_install_db.sh:
  More information to --help
  Write url to knowledge base if something goes wrong
  Fail at once if we can't create a database directory (no reason to continue and write a screenful of not related text)
scripts/mysqld_safe.sh:
  Also allow one to use --data for --datadir (common shortening)
  Added support for --log-basename
  Fail at once if we can't create a log directory
  Fixed bug where we used a pid file name without '.pid' extension
sql/log.cc:
  Create a log file name trough my_once_alloc()  (To get it automaticly freed at exit)
sql/mysql_priv.h:
  Added new prototype
sql/mysqld.cc:
  Added support for --log-basename
  Better help for a lot of log-filename related variables.
sql/rpl_rli.cc:
  Write information that one can use --log-basename
sql/set_var.cc:
  Add log_basename as a readonly variable

9320dca994 Fixed Bug#11764168 "56976: SEVERE DENIAL OF SERVICE IN PREPARED STATEMENTS".
The problem was that server didn't check resulting size of prepared
statement argument which was set using mysql_send_long_data() API.
By calling mysql_send_long_data() several times it was possible
to create overly big string and thus force server to allocate
memory for it. There was no way to limit this allocation.

The solution is to add check for size of result string against
value of max_long_data_size start-up parameter. When intermediate
string exceeds max_long_data_size value an appropriate error message
is emitted.

We can't use existing max_allowed_packet parameter for this purpose
since its value is limited by 1GB and therefore using it as a limit
for data set through mysql_send_long_data() API would have been an
incompatible change. Newly introduced max_long_data_size parameter
gets value from max_allowed_packet parameter unless its value is
specified explicitly. This new parameter is marked as deprecated
and will be eventually replaced by max_allowed_packet parameter.
Value of max_long_data_size parameter can be set only at server
startup.


mysql-test/t/variables.test:
  Added checking for new start-up parameter max_long_data_size.
sql/item.cc:
  Added call to my_message() when accumulated string exceeds
  max_long_data_size value. my_message() calls error handler
  that was installed in mysql_stmt_get_longdata before call
  to Item_param::set_longdata.
  
  The error handler then sets state, last_error and last_errno
  fields for current statement to values which correspond to
  error which was caught.
sql/mysql_priv.h:
  Added max_long_data_size variable declaration.
sql/mysqld.cc:
  Added support for start-up parameter 'max_long_data_size'.
  This parameter limits size of data which can be sent from
  client to server using mysql_send_long_data() API.
sql/set_var.cc:
  Added variable 'max_long_data_size' into list of variables
  displayed by command 'show variables'.
sql/sql_prepare.cc:
  Added error handler class Set_longdata_error_handler.
  This handler is used to catch any errors that can be
  generated during execution of Item_param::set_longdata().
  
  Source code snippet that makes checking for statement's state 
  during statement execution is moved from Prepared_statement::execute()
  to Prepared_statement::execute_loop() in order not to call
  set_parameters() when statement has failed during
  set_long_data() execution. If this hadn't been done
  the call to set_parameters() would have failed.
tests/mysql_client_test.c:
  A testcase for the bug #56976 was added.
