Orkuncakilkaya 254097657e runtime: Log, DateTime.format, Input.text, Path, Mime, Fs, Os and Text keep nothing per call 
Found by reading every builtin (Os.platform's 8 KB per call started it). Log builds its line only at
or above the threshold and frees it; DateTime.format folds through + so its pieces go; Input.text
encodes into one buffer; Path/Mime/Fs/Os free their temporaries on every path; string results of
Text/Path/Mime/DateTime/Os dirs are fresh and Text frees a fresh argument. Reseeded.
runtime_temps.ludic: 19.8 MB -> 0 over 20,000 rounds, 64 KB -> 0 over 200 of file work; clean under
MallocScribble. string_temps still 0.

Raw Blame History

bump: patch type: fix The runtime's text builtins keep nothing a call does not hand back.

  • Log.* builds nothing below the threshold (as documented) and frees the line it writes; a number field's text and a made message go too. A Log.debug in a frame loop left its line every frame.
  • DateTime.format frees each field's digits and each piece joined so far.
  • Input.text() writes the typed text into one buffer instead of joining a string per character.
  • Path.stem / Path.normalize, Mime.of / Mime.sniff, Fs.write_text / copy / mkdir and Os.save_dir / config_dir / cache_dir free their working copies, on every way out.
  • Every string Text.*, Path.*, Mime.*, DateTime.format and the Os directories return is fresh, so a comparison, a + or a print that reads it frees it; a string made for a Text call's argument (Text.to_int(string(n))) is freed once read. examples/lang/runtime_temps.ludic: 20,000 rounds grew 19.8 MB before and 0 after; 200 rounds of file work 64 KB before and 0 after.
