 75 2016-04-10T15:25:38  <GitHub55> [bitcoin] MarcoFalke opened pull request #7853: [qa] py2: Unfiddle strings into bytes explicitly (master...Mf1604-qaBytes) https://github.com/bitcoin/bitcoin/pull/7853
 76 2016-04-10T15:26:09  <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?
 77 2016-04-10T15:26:19  <Chris_Stewart_5> The context I'm looking at is this test case in script_valid.json
 78 2016-04-10T15:26:21  <Chris_Stewart_5> "2147483647", "1ADD 2147483648 EQUAL", "P2SH,STRICTENC", "We can do math on 4-byte integers, and compare 5-byte ones"
 79 2016-04-10T15:27:54  <sipa> the (historically defined) rules are that arithmetic operators don't accept inputs larger than 4 bytes
 80 2016-04-10T15:28:13  <sipa> but adding 2 4-byte integers together may result in one that takes 5 bytes to represent
 81 2016-04-10T15:29:08  <sipa> and stack elements are only restricted to 520 bytes
 82 2016-04-10T15:29:37  <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
 83 2016-04-10T15:31:36  <Chris_Stewart_5> Hmm so basically no arithmetic operation accepts a number > 4 bytes?
 84 2016-04-10T15:34:36  <sipa> indeed
 85 2016-04-10T15:42:48  <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
 86 2016-04-10T15:50:44  <Chris_Stewart_5> sipa: Does that pull request force the script tests to make sure it failed with the correct error?
 87 2016-04-10T15:53:00  <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
 88 2016-04-10T15:53:08  <Chris_Stewart_5> combining*
 89 2016-04-10T15:54:58  <sipa> Chris_Stewart_5: i disagree
 90 2016-04-10T15:55:35  <sipa> almost all tests are doing two nearly identical tests, but with one slight change, where one succeeds and one fails
 91 2016-04-10T15:55:46  <sipa> the interesting part is knowing what makes it succeed or fail
 92 2016-04-10T15:56:02  <sipa> having to look at two different files makes this completely nonobvious
 93 2016-04-10T16:08:48  <Chris_Stewart_5> Actually yeah the more I look at it you are right. Really like the specific script errors.

103 2016-04-10T17:42:30  <michagogo> cfields_: is there any *downside* to having a set of rc1 in there too?
104 2016-04-10T17:42:44  <michagogo> Now I need to massage my tree and reset and stuff :-(
105 2016-04-10T17:43:09  <michagogo> (And force-push etc)
106 2016-04-10T17:43:35  <michagogo> (To avoid breaking anything my scripts all use --ff-only)

109 2016-04-10T17:55:19  <btcdrak> michagogo: no, the rc failed, there is zero point building it.

111 2016-04-10T17:55:55  <michagogo> But given that the sigs exist…
112 2016-04-10T17:56:27  <michagogo> I don't see a significant downside to pulling them in anyway
113 2016-04-10T17:56:49  <michagogo> OTOH this way forces me to fetch, reset, force push, etc
