140's 3, inflate (RFC 1951), written in aup with no new opcode (aup's examples/inflate.aup, codes read a bit at a time from canonical counts as zlib's puff.c): 640 streams zlib made (6,488,480 bytes: random bytes, words, runs and repeats 32,768 back; levels 0, 1, 6, 9 and zlib's five strategies, so stored, fixed and dynamic blocks) inflated to the original's bytes on the three paths, the paths' outputs the same bytes; 240 damaged streams (cut, a bit flipped) read as inflate.py (the Python reference) reads them, 165 refused by both and 75 the same bytes; module_specs in make check: 144 streams on the three paths, 21 cut ones failing and leaving the last bytes; bars: written (no new opcode), three workarounds (lists passed in records: a fn takes no list; the output a list of one: a bytes value is no state; a block's tables built in a fn: a let's list lives in the handler's own block), 132 lines against Python's 81, 1,152 ns an output byte against the same algorithm in C 10.7 (108x) and zlib 3.5 (329x), pure Python 1,214; 191 instructions a byte (a block fn called for each bit was 246 and 1,553 ns: small block fns' inlining is 2c's leftover); the four timing tools' message calls fixed for 4b's API (no keys); CHECKPOINT's direction row
