07:18 < Jmabsd> What IO library / modality is Bitcoin Core using for its TCP data channels and TCP IO scheduling? (e.g. Boost ASIO)

07:20 < gmaxwell> ...

07:20 < gmaxwell> for P2P? the posix sockets api and the freeking os kernel.

07:51 < Jmabsd> gmaxwell: so Bitcoin Core runs its own epoll()/poll()/select() call?

07:51 < sipa> yes

07:51 < Jmabsd> great, thx - actually where is it in the codee?

07:51 < sipa> select()

07:51 < sipa> net.xpp

07:51 < sipa> net.cpp

07:51 < Jmabsd> sipa: select() has a limit of 128 concurrent connections?

07:53 < Jmabsd> yeah anyhow select() is cool, incredibly cross-platform.

07:54 < sipa> no, 1024 iirc on most platforms

08:12 < wumpus> luke-jr: that is true, on windows the SOCKET type exists already and is defined as we defined it; defining it as a different integer type on different platforms is for sure going to break things

08:13 < wumpus> luke-jr: I'm sure it's possible to abstract away 'what is a socket handle' but would be better to wrap it into some class then so that it can't accidentally be treated as integer at all

23:12 < pierre_rochard> I've added three shortcut buttons to apply filters on bitcoinacks.com - "Ready for Review", "Ready for Maintainer", and "User-Facing Only". They are additive, so you can click "Ready for Review" and then "User-Facing Only". Feel free to contact me or file an issue if you would like an additional shortcut button or to modify an existing one

23:13 < pierre_rochard> (These are rough, so for example a PR with two Concept ACKs isn't necessarily ready for a maintainer to take a look at and merge)
