591712f53f BUG#25048 - ERROR 126 : Incorrect key file for table '.XXXX.MYI'; try to
repair it

Multi-table delete that is optimized with QUICK_RANGE reports table
corruption.

DELETE statement must not use KEYREAD optimization, and sets
table->no_keyread to 1. This was ignored in QUICK_RANGE optimization.

With this fix QUICK_RANGE optimization honors table->no_keyread
value and does not enable KEYREAD when it is requested.

2d25da2a4b concurrent-insert can now be set to 2 for concurrent inserts when there is holes in the data file
myisam_max_extra_sort_file_size is depricated
Ensure that myisam_data_pointer_size is honoured when creating new MyISAM files
Changed default value of myisam_data_pointer_size from 4 to 6 to get rid of 'table-is-full' errors

0e7e062465 Fix for BUG#9912: make the test handle both possible optimizer choices 2005-04-21 13:32:46 +04:00

f2829d0386 After merge fixes of merge with 4.1 that included the new arena code.
Fixed (together with Guilhem) bugs in mysqlbinlog regarding --offset
Prefix addresses with 0x for easier comparisons of debug logs
Fixed problem where MySQL choosed index-read even if there would be a much better range on the same index
This fix changed some 'index' queries to 'range' queries in the test suite
Don't create 'dummy' WHERE clause for trivial WHERE clauses where we can remove the WHERE clause.
This fix removed of a lot of 'Using where' notes in the test suite.
Give NOTE instead of WARNING if table/function doesn't exists when using DROP IF EXISTS
Give NOTE instead of WARNING for safe field-type conversions

a46d7542c9 This is first cset for WL#1394 "Optimize index merge when all involved index ranges include only values with equal keys"
The main idea is to exploit the fact that key scans for "key=const" return ordered sequences of rowids.
