Problem was an errornous date that lead to end partition was before the start, leading to a crash. Solution was to check greater or equal instead of only equal between start and end partition. NOTE: partitioning pruning handles incorrect dates differently than index lookup, which can give different results in a partitioned table versus a non partitioned table for queries having 'bad' dates in the where clause. mysql-test/r/partition_pruning.result: Bug#40972: some sql execution lead the whole databse crashing Updated result file mysql-test/t/partition_pruning.test: Bug#40972: some sql execution lead the whole databse crashing Added test. sql/sql_partition.cc: Bug#40972: some sql execution lead the whole databse crashing There can be cases where the start/cur partition is greater than the end partition, so it must not continue, since that can lead to a crash.

problem was that ha_partition::records was not implemented, thus using the default handler::records, which is not correct if the engine does not support HA_STATS_RECORDS_IS_EXACT. Solution was to implement ha_partition::records as a wrapper around the underlying partitions records. The rows column in explain partitions will now include the total number of records in the partitioned table. (recommit after removing out-commented code)

In the ha_partition::position() we didn't calculate the number of the partition of the record. We used m_last_part value instead, relying on that it is set in other place like previous call of a method like ::write_row(). In replication we don't call any of these befor position(). Delete_rows_log_event::do_exec_row calls find_and_fetch_row. In case of InnoDB-based PARTITION table, we have HA_PRIMARY_KEY_REQUIRED_FOR_POSITION enabled, so use position() / rnd_pos() calls to fetch the record. Fixed by adding partition_id calculation to the ha_partition::position() sql/ha_partition.h: Bug #28430 Failure in replication of innodb partitioned tables on row/mixed format. column_bitmaps_signal interface added sql/ha_partition.cc: Bug #28430 Failure in replication of innodb partitioned tables on row/mixed format. Calculate the number of the partition in ha_partition::position(). ha_partition::column_bitmaps_signal() implemented mysql-test/r/partition_pruning.result: Bug #28430 Failure in replication of innodb partitioned tables on row/mixed format. test result fixed

The problem appeared because the same values produced different hash during INSERT and SELECT for VARCHAR data type. Fix: VARCHAR required special treatment to avoid hashing of length bytes (leftmost one or two bytes) as well as trailing bytes beyond real length, which could contain garbage. Fix is done by introducing hash() - new method in the Field class. mysql-test/r/partition_innodb.result: Adding test case mysql-test/r/partition_pruning.result: Fixing test results (results differ due to changes in hash function) mysql-test/t/partition_innodb.test: Adding test case sql/field.cc: Adding generic hash() method, and a special method for VARCHAR. sql/field.h: Adding prototypes for new methods sql/key.cc: Mark columns for write before executinf of set_key_image(). Thanks for Mikael for suggesting this fix. sql/sql_partition.cc: Removing old hash code. Using new methid field->hash() instead.

Final patch ----------- This WL is about using this bitmap in all parts of the partition handler. Thus for: rnd_init/rnd_next index_init/index_next and all other variants of index scans read_range_... the various range scans implemented in the partition handler. Also use those bitmaps in the various other calls that currently loop over all partitions. mysql-test/r/partition_pruning.result: WL# 2986 New results reflecting bitmap being used to determine if a partition is to be included mysql-test/t/partition_pruning.test: WL# 2986 New tests to show bitmap being used in ha_partition sql/ha_partition.cc: WL# 2986 Used work from 2682 and removed the partition select code. Added do {} while loop to any iteration over partitions to now utilise m_part_info->used_partitions bitmap to determine if a partition should be used. sql/ha_partition.h: WL# 2986 Removed unused member sql/handler.h: WL# 2986 Removed unused member sql/opt_range.cc: WL# 2986 Added bitmap_clear_all to clear bitmap prior to pruning DBUG code for testing sql/sql_partition.cc: WL# 2986 Changed < to <=, which fixes the problem with edge cases going awry.
