| | | * MDEV-22728: SIGFPE in Unique::get_cost_calc_buff_size from ↵Varun Gupta2020-06-071-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | prepare_search_best_index_intersect on optimized builds For low sort_buffer_size, in the cost calculation of using the Unique object the elements in the tree were evaluated to 0, make sure to have atleast 1 element in the Unique tree. Also for the function Unique::get allocate memory for atleast MERGEBUFF2+1 keys.

* | | | MDEV-22819: Wrong result or Assertion `ix > 0' failed in read_to_buffer upon ↵Varun Gupta2020-06-111-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | select with GROUP BY and GROUP_CONCAT In the merge_buffers phase for sorting, the sort buffer size is divided between the number of chunks. The chunks have a start and end position (m_buffer_start and m_buffer_end). Then we read the as many records that fit in this buffer for a chunk of the file. The issue here was we were resetting the end of buffer(m_buffer_end) to the number of bytes that was read, this was causing a problem because with dynamic size of sort keys it is possible that later we would not be able to accommodate even one key inside a chunk of file. So the fix was to not reset the end of buffer for a chunk of file.
* | | | Updated optimizer costs in multi_range_read_info_const() and sql_select.ccMonty2020-03-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - multi_range_read_info_const now uses the new records_in_range interface - Added handler::avg_io_cost() - Don't calculate avg_io_cost() in get_sweep_read_cost if avg_io_cost is not 1.0. In this case we trust the avg_io_cost() from the handler. - Changed test_quick_select to use TIME_FOR_COMPARE instead of TIME_FOR_COMPARE_IDX to align this with the rest of the code. - Fixed bug when using test_if_cheaper_ordering where we didn't use keyread if index was changed - Fixed a bug where we didn't use index only read when using order-by-index - Added keyread_time() to HEAP. The default keyread_time() was optimized for blocks and not suitable for HEAP. The effect was the HEAP prefered table scans over ranges for btree indexes. - Fixed get_sweep_read_cost() for HEAP tables - Ensure that range and ref have same cost for simple ranges Added a small cost (MULTI_RANGE_READ_SETUP_COST) to ranges to ensure we favior ref for range for simple queries. - Fixed that matching_candidates_in_table() uses same number of records as the rest of the optimizer - Added avg_io_cost() to JT_EQ_REF cost. This helps calculate the cost for HEAP and temporary tables better. A few tests changed because of this. - heap::read_time() and heap::keyread_time() adjusted to not add +1. This was to ensure that handler::keyread_time() doesn't give higher cost for heap tables than for normal tables. One effect of this is that heap and derived tables stored in heap will prefer key access as this is now regarded as cheap. - Changed cost for index read in sql_select.cc to match multi_range_read_info_const(). All index cost calculation is now done trough one function. - 'ref' will now use quick_cost for keys if it exists. This is done so that for '=' ranges, 'ref' is prefered over 'range'. - scan_time() now takes avg_io_costs() into account - get_delayed_table_estimates() uses block_size and avg_io_cost() - Removed default argument to test_if_order_by_key(); simplifies code

* | | | MDEV-21580: Allow packed sort keys in sort bufferVarun Gupta2020-03-101-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This task deals with packing the sort key inside the sort buffer, which would lead to efficient usage of the memory allocated for the sort buffer. The changes brought by this feature are 1) Sort buffers would have sort keys of variable length 2) The format for sort keys inside the sort buffer would look like |<sort_length><null_byte><key_part1><null_byte><key_part2>.......| sort_length is the extra bytes that are required to store the variable length of a sort key. 3) When packing of sort key is done we store the ORIGINAL VALUES inside the sort buffer and not the STRXFRM form (mem-comparable sort keys). 4) Special comparison function packed_keys_comparison() is introduced to compare 2 sort keys. This patch also contains contributions from Sergei Petrunia.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This task deals with packing the non-sorted fields (or addon fields). This would lead to efficient usage of the memory allocated for the sort buffer. The changes brought by this feature are 1) Sort buffers would have records of variable length 2) Each record in the sort buffer would be stored like <sort_key1><sort_key2>....<addon_length><null_bytes><field1><field2>.... addon_length is the extra bytes that are required to store the variable length of addon field across different records. 3) Changes in rr_unpack_from_buffer and rr_from_tempfile to take into account the variable length of records.

| | | | | | | | | | | | | | | | | | | | | | The function was adjusted to be able to aggregate the counters of the merged elements. Before this change it was not possible to guarantee the correctness of the counters passed to the the call-back parameter walk_action. As a result, when some elements of a Unique object were flushed into disk the function passed to merge_walk() as the call-back parameter could return wrong counters of elements. This could lead to building wrong histograms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This bug could result in returning 0 for the expressions of the form <aggregate_function>(distinct field) when the system variable max_heap_table_size was set to a small enough number. It happened because the method Unique::walk() did not support the case when more than one pass was needed to merge the trees of distinct values saved in an external file. Backported a fix in grant_lowercase.test from mariadb 5.5.
