16:11:02andytoshi:rust update: rust-secp256k1 now has 100% unit test coverage, rust-bitcoin is still a mess. but good progress this week :)
16:16:25gmaxwell:andytoshi: fun timing, I was just looking up to see what you were doing there. What does 100% unit test coverage mean?
16:38:03jtimon:that all the code is at least executed once when running the unittest?

17:46:30antgreen:Hey - I was just reading the logs and was happy to see moxie being discussed yesterday. It's been quiet, but it sounds like people are still hacking with it? Or planning to?
17:49:06stonecoldpat:gmaxwell: sorry had to dash earlier, thought i was late for dog-groom appointment but appears its tomorrow... anyway you the relay you mention should not work IIRC, when you verify a signature (r,s) - you end up with r = kG, so without knowledge of k you wouldn't be able to produce a valid s that will match someone else's r to do a relay
17:50:22stonecoldpat:sorry kG = (x,y) then you heck if x = r from (r,s). its the last step of the verification protocol
18:07:28stonecoldpat:my typing was terrible lemme fix it, anyway the relay attack you mention should not work IIRC, when you verify a signature (r,s), the final step of the verification is to check kG = (x,y), x = r from (r,s). The kG is produced from the 's' component of the (r,s). So an adversary would not be able to produce a valid signature (r,s) to pull off the attack without knowing k or d.*****
18:10:56gmaxwell:stonecoldpat: thats not correct.

19:18:30andytoshi:gmaxwell: i run the unit test binary (produced by `cargo test`) through kcov; it says all but one instrumented line is covered (and that line is a `}` so i guess this is a bug)
19:19:07andytoshi:gmaxwell: there are some LOC that are not instrumented, i think the tool is not counting it, so this is not totally accurate ... but i think i've hit every error path
