| timotimo | diakopter: hack.p6c.org/~timo/minimized_dumpon...ngs.tar.gz - 4.3 megabytes (compressed) of .moarvm files that cause hangs when loading them with --dump | 10:53 | |
| watching the minimization is so fascinating | 11:52 | ||
| it throws out ~99% of all bytes that used to have some value and replaces them with a "0" | |||
| and then hexdumping them gives you lots and lots of 0s in the right column and some holes in between | |||
| that's quite a visual experience, which is probably why they chose that particular value | 11:53 | ||
| jnthn | OK, I have Perl 6 / Moar time for the rest of the day \o/ | 12:35 | |
| m: my $s = Buf.new([255, 254, 72, 0, 101, 0]).decode("utf-16"); say $s.perl | 12:37 | ||
| camelia | rakudo-moar dc9552: OUTPUT«"He\0"» | ||
| timotimo | that doesn't look right, does it? | ||
| jnthn | Indeed :) | ||
| We got a PR to fix it :) | |||
| timotimo | nice! | ||
| jnthn | m: use Test; is Buf.new([255, 254, 72, 0, 101, 0]).decode("utf-16"), 'He', 'utf-16 BOM handled ok' | 12:38 | |
| camelia | rakudo-moar dc9552: OUTPUT«not ok 1 - utf-16 BOM handled ok# Failed test 'utf-16 BOM handled ok'# at /tmp/voKnj34jgt line 1# expected: 'He'# got: 'He␀'» | ||
| dalek | arVM: 45bf04c | (David Warring)++ | src/strings/utf16.c: adjust byte count when UTF-16 BOM marker consumed Something I noticed in Rakudo, when experimenting with UTF-16 BOM markers. For example: % perl6 -e'my $s = Buf.new([255, 254, 72, 0, 101, 0]).decode("utf-16"); say $s.perl' "He\0" The 2-byte "\xFF\FE" BOM marker is consumed, but the byte count hasn't been adjusted, so it's running past the end of the string. |

| timotimo | i went through the contents of "minimized_dumponly_hangs.tar.gz" and the only one that actually crashes at all is one that reads beyond the serialized blob when getting a frames' locals set up. so that'd also be handled whenever i get that range check code working | 13:59 | |

| dalek | Heuristic branch merge: pushed 26 commits to MoarVM/cache_sc_idx by diakopter | 22:07 | |
| diakopter | bug: when doing a strawberry build, rakudo tries to run nmake instead of gmake (and it fails) | 22:12 | |
| also, it does this: Missing or wrong version of dependency 'gen\moar\stage2\QRegex.nqp' (from 'gen/moar/m-ModuleLoader.nqp') at <unknown>:1 (blib/Perl6/ModuleLoader.moarvm:<dependencies+deserialize>) | 22:13 | ||
