Benjamin Otte	26696a741e	timsort: Add change tracking to gtk_tim_sort_step()	2020-07-22 14:04:40 +02:00
Benjamin Otte	a209e54b8f	timsort: Add gtk_tim_sort_set_max_merge_size() ... Makes the SOrtListModel responsive when incrementally sorting. By making it configurable we can avoid losting performance in the non-incremental case.	2020-07-22 14:04:40 +02:00
Benjamin Otte	8921dadaa1	timsort: Make sure merges don't take too long ... Limit the size of the merged areas and thereby chunk larger merges into smaller ones.	2020-07-22 14:04:40 +02:00
Benjamin Otte	cbad8ec2e4	timsort: Add gtk_tim_sort_set_runs() ... ... and use it in the SortListModel Setting runs allows declaring already sorted regions so the sort does not attempt to sort them again. This massively speeds up partial inserts where we can reuse the sorted model as a run and only resort the newly inserted parts.
