08:25 < GitHub55> [bitcoin] MarcoFalke opened pull request #7853: [qa] py2: Unfiddle strings into bytes explicitly (master...Mf1604-qaBytes) https://github.com/bitcoin/bitcoin/pull/7853
08:26 < Chris_Stewart_5> Can some one explain to me why we can sometimes have 5 byte numbers in Script? When is it ok to have numbers larger than 4 bytes? 
08:26 < Chris_Stewart_5> The context I'm looking at is this test case in script_valid.json
08:26 < Chris_Stewart_5> "2147483647", "1ADD 2147483648 EQUAL", "P2SH,STRICTENC", "We can do math on 4-byte integers, and compare 5-byte ones"
08:27 < sipa> the (historically defined) rules are that arithmetic operators don't accept inputs larger than 4 bytes
08:28 < sipa> but adding 2 4-byte integers together may result in one that takes 5 bytes to represent
08:29 < sipa> and stack elements are only restricted to 520 bytes
08:29 < sipa> so while you can't feed the output of such an addition to another addition for example, you can feed it to other operators that don't interpret it as a number
08:31 < Chris_Stewart_5> Hmm so basically no arithmetic operation accepts a number > 4 bytes? 
08:34 < sipa> indeed
08:42 < GitHub139> [bitcoin] sipa opened pull request #7854: [0.12 backport] Various script_tests improvements from master and #7818 (0.12...refactorscriptests_12) https://github.com/bitcoin/bitcoin/pull/7854
08:50 < Chris_Stewart_5> sipa: Does that pull request force the script tests to make sure it failed with the correct error?
08:53 < Chris_Stewart_5> also what is the reasoning behind combing script_valid & script_invalid? From a outsiders perspective it is much easier to figure what is going on having two individual files
08:53 < Chris_Stewart_5> combining* 
08:55 < sipa> Chris_Stewart_5: i disagree
08:55 < sipa> almost all tests are doing two nearly identical tests, but with one slight change, where one succeeds and one fails
08:55 < sipa> the interesting part is knowing what makes it succeed or fail
08:56 < sipa> having to look at two different files makes this completely nonobvious
09:08 < Chris_Stewart_5> Actually yeah the more I look at it you are right. Really like the specific script errors.

10:42 < michagogo> cfields_: is there any *downside* to having a set of rc1 in there too?

10:56 < michagogo> I don't see a significant downside to pulling them in anyway
10:56 < michagogo> OTOH this way forces me to fetch, reset, force push, etc
