ON 64 BIT MACHINES
PROBLEM: When sorting index during repair of
myisam tables, due to improper casting
of buffer size variables value of myisam_
sort_buffer_size is not set greater than
4GB.
SOLUTION: Proper casting of buffer size variable.
myisam_buffer_size changed to unsigned
long long to handle size > 4GB on
linux as well as windows.

CASES RESETS DATA POINTER TO SMAL
ISSUE: Myisamchk doing sort recover
on a table reduces data_file_length.
Maximum size of data file decreases,
lesser number of rows are stored.
SOLUTION: Size of data_file_length is
fixed to the original length.

Give more information when finding an error in a MyISAM table.
When killing system thread, use KILL_SYSTEM_THREAD instead of KILL_CONNECTION to make it easier to ignore the signal in sensitive context (like auto-repair)
Added new kill level: KILL_SERVER that will in the future to be used to signal killed by shutdown.
Add more warnings about killed connections when warning level > 3
include/myisamchk.h:
Added counting of printed info/notes
mysys/mf_iocache.c:
Remove duplicate assignment
sql/handler.cc:
Added test of KILL_SERVER
sql/log.cc:
Ignore new 'kill' error ER_NEW_ABORTING_CONNECTION when requesting query error code.
sql/mysqld.cc:
Add more warnings for killed connections when warning level > 3
sql/scheduler.cc:
Added checks for new kill signals
sql/slave.cc:
Ignore new kill signal ER_NEW_ABORTING_CONNECTION
sql/sp_head.cc:
Fixed assignment to bool
Added testing of new kill signals
sql/sql_base.cc:
Use KILL_SYSTEM_THREAD to auto-kill system threads
sql/sql_class.cc:
Add more warnings for killed connections when warning level > 3
thd_killed() now ignores KILL_BAD_DATA and THD::KILL_SYSTEM_THREAD as these should not abort sensitive operations.
sql/sql_class.h:
Added KILL_SYSTEM_THREAD and KILL_SERVER
sql/sql_connect.cc:
Added handling of KILL_SERVER
sql/sql_insert.cc:
Use KILL_SYSTEM_THREAD to auto-kill system threads
Added handling of KILL_SERVER
sql/sql_parse.cc:
Add more warnings for killed connections when warning level > 3
Added checking that thd->abort_on_warning is reset at end of query.
sql/sql_show.cc:
Update condition for when a query is 'killed'
storage/myisam/ha_myisam.cc:
Added counting of info/notes printed
storage/myisam/mi_check.c:
Always print an an error if we find data errors when checking/repairing a MyISAM table.
When a repair was killed, don't retry repair.
Added assert if sort_get_next_record() returned an error without an error message.
Removed nonsence check "if (sort_param->read_cache.error < 0)" in repair.
storage/myisam/myisamchk.c:
Added counting of notes printed
storage/pbxt/src/thread_xt.cc:
Better error message.
Added more printing of errors to myisamchk.
mysys/mf_iocache.c:
Write error message if failed seek.
sql/table.cc:
Fixed buffer overflow bug:
- It's not enough to check for mysql_version to to detect partion indicator as the version may have been updated by mysql_upgrade.
storage/myisam/ha_myisam.cc:
Don't log same error twice.
Don't reset log_all_errors if it's set
storage/myisam/mi_check.c:
Fixed bug that caused repair() to not report error if called twice (as when doing retry)
More printing of errors.
storage/myisam/sort.c:
Set my_errno in case of out of memory errors.
- 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).
