| MasterDuke | B1B3773A05C0ED0176787A4F1574FF0075F7521E vs 3C8B9F4B983AFA9F644D26E2B34FA3E03A2BEF16, i think that's sufficiently different | 01:13 | |
| what i am trying to figure out now is why the implementation i copied from git's source is giving different results... | 01:14 | ||
| it seems to be a bit faster than ours. however, nqp::sha1 actually spends most of the time in MVM_string_utf8_encode_substr when you sha1 a large string (like the contents of a source file) | 01:25 | ||
| but making that faster seems quite a bit more involved. and i think is going to require something i've brought up before, which is making more specific functions. currently the grapheme iterator checks the string's storage type at every call | 01:26 | ||
| it should predict perfectly, but it would be even faster not to have that at all... | |||
| jnthn, nine, timo, japhb, etc: any ideas for how to make MVM_string_utf8_encode_substr faster? my thought right now is something like creating MVM_string_gi_get_grapheme_for_(32|ascii|8) functions, but i'm open to other suggestions | 01:28 | ||

| vrurg | jnthn: Do you actually mind merging github.com/rakudo/rakudo/pull/5117? | 21:41 | |
| MasterDuke | looks like git's sha1 implementation does different padding, but i'm not sure why | 22:05 | |
| hm, and the outputs don't even seem to match if i don't pad either... | 22:08 | ||
| jnthn | vrurg: I'll try and look at it tomorrow; I'm finally free from $dayjob for a while | 23:16 | |
| vrurg: If I still haven't commented on it tomorrow, just merge it | |||
| vrurg | jnthn: Thanks! I wanted it because stumbled upon an error without any location. Debugging is kind of a nightmare then. :) | 23:17 | |
