03:25 < MarcoFalke> So why does travis fail all pulls with ImportError: No module named 'zmq'?
03:26 < paveljanik> MarcoFalke, python-qmz not installed.
03:26 < paveljanik> I'm just about to write to you, that we should make a conditional in the zmq tests to prevent this ;-)
03:27 < paveljanik> README.md contains: sudo apt-get install python-zmq
03:28 < paveljanik> and of course install this module in travis
03:30 < MarcoFalke> https://github.com/bitcoin/bitcoin/blob/65aecda52d0d2179f77d675dc305225a1566c48f/.travis.yml#L46 https://github.com/bitcoin/bitcoin/blob/77b637f20e8cb91cf007bf416b603ca362385cdb/.travis.yml#L46
03:31 < MarcoFalke> It is installed
03:31 < MarcoFalke> Am I missing something?
03:34 < paveljanik> Is there a log from the travis initialization to check?
03:36 < paveljanik> and is there such module available at all? ;-)
03:36  * paveljanik doesn't know...
03:36 < MarcoFalke> Oh the cache is messed up
03:36 < MarcoFalke> It fetches from master (which is py3) but the pulls are still py2
03:36 < MarcoFalke> Just a guess
03:39 < paveljanik> yes, maybe.
03:41 < paveljanik> Does it help to rebase such PR?
03:42 < GitHub91> [bitcoin] jonasschnelli opened pull request #8018: Autofind rpc tests --srcdir (master...2016/05/fix_test_srcdir) https://github.com/bitcoin/bitcoin/pull/8018

11:00 < jl2012> maaku, no matter what we do, when no one is mining, an attacker can easily fork the network by mining a long non-segwit chain after activation
11:00 < jl2012> unless we have hashrate to keep the chain growing, which is burning money
11:04 < BlueMatt> hmmm...sipa so I need to keep around a list of node pointers I can send messages to in main.cpp...would be a huge shame to put CNode* back in logic there :/
11:04 < BlueMatt> any ideas
11:04 < BlueMatt> or, wait, who introduced NodeId
11:06 -!- GAit [~GAit@212.91.77.40] has joined #bitcoin-core-dev
11:07 < gmaxwell> jl2012: maaku's concern is that you we should give people time to update so their nodes will ignore that fork.
11:07 < gmaxwell> I don't share the concern.
11:08 < gmaxwell> (or rather, I share it but believe that we will end up giving them adequate time, without having to delay further.)
11:10 < jl2012> i hope to see it live on testnet as early as possible, so we could start testing the dynamics of upgraded and non-upgraded nodes
11:10 < jl2012> and I'm sure it will be attacked, intentionally or unintentionally
11:11 < jl2012> unless we keep mining it
11:11 < gmaxwell> jl2012: if nodes are already upgraded to enforce, then _full nodes_ (which is 99% of what exists on testnet) won't notice any such attack.
11:12 < jl2012> but the point to test it on testnet is to examine the interaction between upgraded and non-upgraded nodes
11:13 < jl2012> if we just want upgraded nodes, we already have segnet
11:15 < jl2012> and if upgraded nodes have minority hashrate, we are actually implementing a segnet under the name of testnet
11:15 < instagibbs> jl2012, you can do that in segnet too
11:15 < gmaxwell> we can also spin up a new testnet that is mixed.
11:16 < gmaxwell> which would not disrupt other people's testing that is unrelated to segwit.
11:17 < jl2012> actually I'm running a non-upgraded node on the segwit. Probably the only one

11:22 < sipa> BlueMatt: but perhaps net can have a function to send a particular message to a list of nodeids
11:23 < sipa> BlueMatt: alternatively, you can keep a list of CNode* pointers around, but you'll need cleanup logic in FinalizeNode to remove any reference to a node when it disappears
11:24 < BlueMatt> sipa: yea, I mean i was thinking about CNode* references...but that kinda defeats the purpose of NodeId
11:24 < BlueMatt> sipa: in fact, any solution kinda defeats the purpose of NodeId...might as well kill NodeId if we have back-and-forward references between CNodes and NodeIds

11:32 < sipa> BlueMatt: i disagree
11:32 < sipa> BlueMatt: net should not expose CNode
11:32 < sipa> and only expose abstract identifiers
11:32 < sipa> the fact that you need back-and-forth references is a side effect of the logic now being split between net and main
11:33 -!- BashCo_ [~BashCo@unaffiliated/bashco] has quit [Ping timeout: 244 seconds]
11:33 < BlueMatt> sipa: so you mean that we /should/ have an interface to send to a nodeid, because we shouldn't expose CNode at all, and pfrom should, in fact, be a nodeid?
11:34 -!- GAit [~GAit@212.91.77.40] has quit [Quit: Leaving.]
11:34 < sipa> BlueMatt: yup
11:34 < sipa> but i expect that code to undergo very significant changes after cory's net changes
11:35 < BlueMatt> meh, I mean /all/ processing should happen in net imo...the fact that main knows /anything/ about the p2p protocol is bad
11:35 < BlueMatt> but, indeed, its kinda all up in the air as cory refactors net
11:35 < BlueMatt> I'll add a CNode* ref for now, with the expectation that it will dissapear soonish
11:37 < sdaftuar> sipa: fyi, according to morcos it worked relatively easily to convert mapTx's txid index to an unordered_map.
11:37 < sipa> sdaftuar: oh, sorry to not report back; yes, it was trivial :)
11:37 < sipa> doing it as part of a slighly larger change
11:37 < sdaftuar> cool!
