Michael Widenius c4f5326bb7 MDEV-6255 DUPLICATE KEY Errors on SELECT .. GROUP BY that uses temporary and filesort. The problem was that my_hash_sort didn't properly delete end-space characters properly, so strings that should compare identically was seen as different strings. (Space was handled correctly, but not NBSP) This caused duplicate key errors when a heap table was converted to Aria as part of overflow in group by. Fixed by removing all characters that compares as end space when creating a hash. Other things: - Fixed that --sorted_results also works for errors in mysqltest. - Speed up hash by not comparing strings that has different hash. - Speed up many my_hash_sort functions by using registers to calculate hash instead of pointers. This was previously done for some functions, but not for all. - Made a macro of the hash function, to simplify code and to be able to experiment with new hash functions. client/mysqltest.cc: Fixed that --sorted_results also works for error messages. mysql-test/r/ctype_partitions.result: New test to ensure that partitions on hash works mysql-test/suite/multi_source/gtid.result: Updated result mysql-test/suite/multi_source/gtid.test: Test that --sorted_result works for error messages mysql-test/suite/multi_source/gtid_ignore_duplicates.result: Updated result mysql-test/suite/multi_source/gtid_ignore_duplicates.test: Updated result mysql-test/suite/multi_source/load_data.result: Updated result mysql-test/suite/multi_source/load_data.test: Updated result mysql-test/t/ctype_partitions.test: New test to ensure that partitions on hash works storage/heap/hp_write.c: Speed up hash by not comparing strings that has different hash. storage/maria/ma_check.c: Extra debug strings/ctype-bin.c: Use macro for hash function strings/ctype-latin1.c: Use macro for hash function Use registers to calculate hash (speedup) strings/ctype-mb.c: Use macro for hash function Use registers to calculate hash (speedup) strings/ctype-simple.c: Use macro for hash function Use same variable names as in other my_hash_sort functions. Update my_hash_sort_simple() to properly remove end space (patch by Bar) strings/ctype-uca.c: Ignore duplicated space inside strings and end space in my_hash_sort_uca(). This fixed MDEV-6255 Use macro for hash function Use registers to calculate hash (speedup) strings/ctype-ucs2.c: Use macro for hash function Use registers to calculate hash (speedup) strings/ctype-utf8.c: Use macro for hash function Use registers to calculate hash (speedup) strings/strings_def.h: Made a macro of the hash function, to simplify code and to be able to experiment with new hash functions.		11 years ago
