practicalswift	693247b82b	[test] Speed up fuzzing by ~200x when using afl-fuzz Enable the `afl-clang-fast++` features deferred forkserver (`__AFL_INIT`) and persistent mode (`__AFL_LOOP(1000)`). Before this patch: ``` $ afl-fuzz -i input -o output -m512 -- src/test/test_bitcoin_fuzzy [] Validating target binary... [!] WARNING: The target binary is pretty slow! See /usr/local/share/doc/afl/perf_tips.txt. [+] Here are some useful stats: Test case count : 1 favored, 0 variable, 1 total Bitmap range : 1072 to 1072 bits (average: 1072.00 bits) Exec timing : 20.4k to 20.4k us (average: 20.4k us) … exec speed : 57.58/sec (slow!) exec speed : 48.35/sec (slow!) exec speed : 53.78/sec (slow!) ``` After this patch: ``` $ afl-fuzz -i input -o output -m512 -- src/test/test_bitcoin_fuzzy [] Validating target binary... [+] Persistent mode binary detected. [+] Deferred forkserver binary detected. [+] Here are some useful stats: Test case count : 1 favored, 0 variable, 1 total Bitmap range : 24 to 24 bits (average: 24.00 bits) Exec timing : 114 to 114 us (average: 114 us) … exec speed : 15.9k/sec exec speed : 13.1k/sec exec speed : 15.1k/sec ```	8 years ago
