07:02 < nickler> meeting?
07:02 < sipa> meeting.
07:02 < hebasto> hi
07:04 < nickler> real_or_random may not be here today
07:04 < nickler> topics?
07:04 < sipa> I don't have anything really.
07:04 < nickler> me neither
07:04 < sipa> *PR
07:04 < sipa> Except happy to see your review on the Jacobi PI.
07:06 < nickler> Yeah that was fun thanks to the detailed safegcd doc.
07:06 < roconnor> How do we feel about https://github.com/bitcoin-core/secp256k1/pull/1210  Should we just close it?
07:07 < real_or_random> ah sorry, I don't have anything... expect that I'll be gone for 3-4 weeks starting from March 11
07:07 < nickler> sipa: besides my nit, have all the review comments been addressed?
07:07 < real_or_random> so I'd like to get jacobi merged before that, and I'd like to get merged (or at least ACK) cmake before that, so that my absence doesn't get in the way  
07:08 < real_or_random> but that sounds realistic given nickler's review on jacobi now :)
07:08 < sipa> roconnor: I think so; it seems to really boil down to fighting compiler intricacies at that point.
07:16 < sipa> I'll look into making the Jacobi code only defined for coprime inputs.
07:19 < roconnor> Why only coprime?
07:27 < sipa> The algorithm we have doesn't converge for non-coprime inputs IIRC.
07:27 < sipa> Which is why it needs special handling for x=0.
07:30 < sipa> Maybe it's just x=0 for which it doesn't converge; I need to swap some context back in.
07:34 < nickler> the algo stops when f=1 and f is supposed to contain the gcd, so if the inputs aren't coprime it doesn't converge

07:37 < sipa> Right!

07:40 < roconnor> How are you going to tell if the inputs are coprime?
07:41 < sipa> I'm not. I'm planning on just defining the function to only work for coprime inputs.
07:41 < sipa> Which is trivial to satisfy in actual operation, as it uses a prime modulus, so all it needs is avoiding x=0 as input.
