17:23 < BlueMatt> is there some place where the flags required for a context passed to a given function is documented?
17:23 < BlueMatt> I cant seem to find it in the header file(s)
17:25 < sipa> for some it is listed at least, secp256k1_ecdsa_verify e.g. says "context object, initialized for verification."
17:25 < BlueMatt> hmm, i didnt read them all but definitely seems to be a minority
17:25 < BlueMatt> is there some trivially-describable rule which I could apply?
17:26 < sipa> generally, the ones that operate on secret data and do EC arithmetic will require sign-initialization
17:26 < sipa> and others that do EC arithmetic require verify-initialization
17:26 < BlueMatt> I suppose "a secret key is passed as an argument" isnt sufficiently descriptive
17:27 < sipa> the secret key tweak functions for example operate on secret data, but don't do EC arithmetic
17:28 < BlueMatt> right
17:28 < sipa> so they don't need anything
17:28 < sipa> i think the ones in secp256k1.h itself at least are all correct
17:28 < BlueMatt> ok, well I'll take a guess and see if andytoshi yells at me in review.
17:28 < sipa> if it's not listed for a function, it doesn't need anything
17:28 < BlueMatt> ohhhhh, thats helpful
17:29 < BlueMatt> ok, well then a feature request this is! Maybe mention "with any flags" instead of not mentioning it at all on functions that dont care :)
17:30 < sipa> sgtm
17:30 < sipa> i went through all of them, i don't see any obvious misses
17:30 < BlueMatt> thanks
17:49 < andytoshi> good catch
17:49 < andytoshi> i was about to complain "100% of the functions should be labeled" but i realize "no information" is not actually a clear label :P
17:50 < sipa> turns out, in fact 100% of the functions are correctly labeled (or close to 100%, i may have overlooked one or two)
17:50 < sipa> only in a confusing manner
