* all history writers always append (not overwrite) history files * they reload history if they detect that file length has changed since last write * they trim history file only when it grows 4 times longer than MAXLINES * they do this atomically by creating new file and renaming it to old Unfortunately, this comes at a price: function old new delta load_history - 346 +346 read_line_input 3155 3358 +203 new_line_input_t 17 31 +14 ...irrelevant small jitter... ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 5/5 up/down: 573/-13) Total: 560 bytes
