japhb timotimo: The good thing is that PNG images of terminals aren't terribly large, so if I don't put very many in, it won't be too big. Still, I wonder about the relative value of having screenshots inside or outside the repo (and if the latter, where to put them). Another question is whether I want to combine several screenshots into one big animation. 02:38

AlexDaniel japhb: I usually just drag and drop required images into a comment field, it uploads them to somewhere on github 13:56
japhb: then I just copy that link into markdown files 13:57
absolutely zero guarantees that this will last, but in practice it does

clever
i sometimes upload screenshots and little screencasts/gifs to discord and use their CDN for this same purpose :)

MasterDuke timotimo: have you seen github.com/perl6/nqp/issues/560 ? i can repro locally. if i add an fprintf in MVM_bigint_is_prime it's printing the given value for b (the number of rounds) 20:29
a bug in libtommath?
japhb Ooh, AlexDaniel, that's a great idea. Especially if the comment field is in an issue on the very repo I'm wanting an image in ... 20:30
timotimo huh, it's claiming that 3 isn't prime if you do only 256 rounds?
MasterDuke no. if you do more than 256 rounds
m: use nqp; say nqp::isprime_I(3, 256); say nqp::isprime_I(3, 257); 20:31

japhb So it's not just that we chose a few random bad values, it's consistently wrong past that point. 20:34
timotimo maybe the MVM_BIGINT_IS_BIG check is derped 20:35
MasterDuke /* valid value of t? */ if (t <= 0 || t > PRIME_SIZE) { return MP_VAL; } 20:36
tommath.h:455: #define PRIME_SIZE 31tommath.h:457: #define PRIME_SIZE 256
timotimo we don't check the return value of mp_prime_is_prime
we should potentially throw if what it returns is not MP_OKAY 20:37
MasterDuke yep
timotimo can you check the return value it gives for those cases?
ok, who wants to answer the ticket?
and who wants to insert the return value check and exception throw? 20:39
MasterDuke i can probably get around to it later, but don't let me hold anyone else back 20:41
timotimo OK, i'll write a brief response on the ticket 20:42
