Georgi Kodinov	21a01bd60e	fixed a valgrind warning in partition_pruning	16 years ago
Mattias Jonsson	401fb7c6fb	Bug#20577: Partitions: use of to_days() function leads to selection failures Problem was that the partition containing NULL values was pruned away, since '2001-01-01' < '2001-02-00' but TO_DAYS('2001-02-00') is NULL. Added the NULL partition for RANGE/LIST partitioning on TO_DAYS() function to be scanned too. Also fixed a bug that added ALLOW_INVALID_DATES to sql_mode (SELECT * FROM t WHERE date_col < '1999-99-99' on a RANGE/LIST partitioned table would add it).	16 years ago

Alexey Botchkov	a206d672e8	Bug#38083 Error-causing row inserted into partitioned table despite error problems are located in the sql_partition.cc where functions calculation partition_id don't expect error returned from item->val_int(). Fixed by adding checks to these functions.

mattiasj@client-10-129-10-137.upp.off.mysql.com	a6a9774849	Bug#31931 Partitions: unjustified 'mix of handlers' error message Problem was that the mix of handlers was not consistent between CREATE and ALTER changed so that it works like: - All partitions must use the same engine AND it must be the same as the table. - if one does NOT specify an engine on the table level then one must either NOT specify any engine on any partition/subpartition OR for ALL partitions/subpartitions Note: that after a table have been created, the storage engine is specified for all parts of the table (table/partition/subpartition) and so when using alter, one does not need to specify it (unless one wants to change the storage engine, then one have to specify it on the table level)	18 years ago
sergefp@mysql.com	41404ec52e	BUG#27927:Partition pruning not optimal with TO_DAYS and YEAR functions - Introduced val_int_endpoint() function which converts between func argument intervals and func value intervals for monotonic functions. - Made partition interval analyzer use part_expr->val_int_endpoint() to check if the edge values should be included.	18 years ago
istruewing@chilla.local	dc82068c96	Bug#26827 - table->read_set is set incorrectly, causing update of a different column For efficiency some storage engines do not read a complete record for update, but only the columns required for selecting the rows. When updating a row of a partitioned table, modifying a column that is part of the partition or subpartition expression, then the row may need to move from one [sub]partition to another one. This is done by inserting the new row into the target [sub]partition and deleting the old row from the originating one. For the insert we need a complete record. If an above mentioned engine was used for a partitioned table, we did not have a complete record in update_row(). The implicitly executed write_row() got an incomplete record. This is solved by instructing the engine to read a complete record if one of the columns of the partition or subpartiton is to be updated. No testcase. This can be reproduced with Falcon only. The engines contained in standard 5.1 do always return complete records on update.	19 years ago
monty@mysql.com/narttu.mysql.fi	088e2395f1	WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c	19 years ago
kostja@bodhi.local	b42b416400	Remove unnecessary casts to uchar. The casts are stemming from the lexer API which internally uses unsigned char variables to address its state map. The implementation of the lexer should be internal to the lexer, and not influence the rest of the code.	19 years ago
