Height of the highest block in file_num whose undo data has been written.
Synopsis
Declared in <node/blockstorage.h>
int undo_height = {0};Description
Block data is written to block files in download order, but undo data is written in validation order (usually by height). Undo files are trimmed once the corresponding block file is finalized and these heights match. This is a heuristic and may trim too early or too late in some cases.
