[06:58] CIA-32	libzmq: 03Martin Sustrik 07master * rf8bf3a4 10/ (15 files): Rename i_inout to i_engine_sink ...
[07:38] jonnydee	hi, I tried to load zeromq vs 2008 solution, but it complains that inproc_lat and inproc_thr is missing. And indeed there are no such projects. Any ideas? (I downloaded version 2.1.7)
[07:41] jonnydee	(of course, I downloaded the windows version)
[07:42] jonnydee	hello? anybode here?
[07:46] guido_g	try the mailing list, there will be more windows users
[07:47] jonnydee	guido_g: ok, thanks
[08:01] sustrik	johnydee: let me check
[08:01] th	jonnydee: sustrik: i can confirm that exactly.
[08:02] th	just gave it a first try to build on win7 with msvc2008 yesterday
[08:03] th	i used the Windows SDK 7.0 to be exact
[08:04] sustrik	johnydee, th: ok, found the problem
[08:05] th	great
[08:07] sustrik	unfortunately, it will be fixed only with the next release
[08:07] sustrik	in the meantime you can build from git repo
[08:07] th	sustrik: but probably in git already?
[08:08] sustrik	it's a packaging problem
[08:08] th	ah
[08:08] sustrik	so git repo would work even without any patch
[08:08] th	whats the difference anyways between git and the zip? except for the version tag of course
[08:09] sustrik	get the 2.1.7 tag from the git
[08:09] sustrik	it should be exactly the same as packaged 2.1.7
[08:09] sustrik	except for the files missing accidentally in the package, of course
[08:11] th	sustrik: so the .zip is just a `git archive --format=zip c35f65a82f1d > zeromq-2.1.7.zip` something?
[08:12] sustrik	iirc to build the archive do "make dist"
[08:12] th	i'll test that
[08:12] sustrik	you need autotools to make it work though
[08:12] sustrik	so windows is not an option
[08:13] sustrik	well, unless you use minggw
[08:14] sustrik	alternatively, inproc perf tests are not needed for libzmq to work
[08:14] sustrik	so you can just remove the two projects from the msvc solution
[08:16] th	that was my thought yesterday, but then i got distracted
[08:17] th	it probably wont work to prepare the dist on a linux box for windows, right?
[08:18] sustrik	th: it will
[08:18] sustrik	that's the way we are doing it
[08:18] th	ahh - so all i need to do is checkout 2.1.7 tag from git, run ./autogen.sh and zip it for windows?
[08:19] sustrik	you can't use 2.1.7's packaging mechanism as that's where the bug is
[08:20] sustrik	you can wait while i'll publish the patch (to happen shortly)
[08:20] th	there is a `fix scope on Windows includes` and then a reversion of that... which revision exactly fixes that bug?
[08:20] th	ahhh
[08:20] th	dang.
[08:20] sustrik	apply it to 2.1.7
[08:20] th	of course
[08:20] th	got it
[08:20] sustrik	etc,
[08:20] sustrik	the sequence of steps to build the package"
[08:20] sustrik	./autogen.sh
[08:20] sustrik	./configure
[08:21] sustrik	make dist
[08:21] sustrik	the zip will be created in the root libzmq directory
[08:21] th	great
[08:25] sustrik	th: the patch was posted to the mailing list
[08:25] sustrik	can you try it and let me know whether it solves the problem?
[08:25] th	will do
[08:25] sustrik	thanks
[08:26] alkemann	hey. I am trying to send "post/products/{"json":"format"} and i get Operation cannot be accomplished in current state - any idea?
[08:26] alkemann	breaking on recv()
[08:29] sustrik	REQ and REP sockets work in sync manner
[08:29] sustrik	send, recv, send, recv, ...
[08:29] sustrik	when you try to do send, send or recv, recv you get this error
[08:30] alkemann	hm. weird thanks ill look
[08:32] silvano	http://www.ilfattoquotidiano.it/2011/06/27/vietare-le-droghe-funziona/127569/
[08:50] th	sustrik: fix confirmed. now only the pgm thing fails for me, probably because some missing dependenies
[08:51] th	sustrik: thanks for that!
[08:51] sustrik	you are welcome
[08:51] sustrik	thanks for testing it
[08:51] th	i would publish the fixed-zip, but due to a difference in autoconf versions there is introduced a lot of "noise"
[08:52] sustrik	th: no need, that's up to pieter to do
[08:52] sustrik	he's 2-1 maintainer
[09:03] CIA-32	libzmq: 03Martin Sustrik 07master * r543ad30 10/ builds/msvc/Makefile.am : Packaging for MSVC build fixed ...
[10:51] jonnydee	sustrik: Thank you very much for your fast response :)
[10:54] sustrik	np
[12:47] john	quick question: when connecting a socket to a ip and port, tcp://:5000 for example, does the mean any IP on the network?
[12:49] sustrik	* works only for bind
[12:50] sustrik	and means 'all the NICs'
[12:50] john	so eth0 and wifi?
[12:51] sustrik	and loopback
[12:53] john	Right now connecting with * seems to work but perhaps thats because everything is on one computer right now. So this won't work if I move part of my system to another computer on the network.
[12:56] john	sustrik: you're saying I should specify the ip when connecting so 127.0.0.1 if on the same computer? I guess I could just try and see if * works across the LAN.
[12:58] guido_g	sigh
[12:59] guido_g	star means "any", ip is an appartment block, port the appartment no.; connect means go and find block and appartment; with find any apparment block it doesn't make sense
[13:00] sustrik	* translates to 0.0.0.0
[13:00] sustrik	which is IPADDR_ANY
[13:01] sustrik	works only for binding, never for connecting
[13:01] sustrik	you can't connect to 0.0.0.0, there's no such box
[14:19] th	sustrik: actually on linux localhost responds to 0.0.0.0
[14:19] sustrik	does it?
[14:19] th	% ssh 0.0.0.0
[14:19] th	The authenticity of host '0.0.0.0 (0.0.0.0)' can't be established.
[14:19] sustrik	what does it connect to?
[14:19] th	RSA key fingerprint is ...
[14:19] th	the host i'm sitting on
[14:20] th	% ping 0
[14:20] th	PING 0 (127.0.0.1) 56(84) bytes of data.
[14:20] th	64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.029 ms
[14:20] th	or: PING 0.0.0.0 (127.0.0.1) 56(84) bytes of data.
[14:20] th	and thats not a feature of ssh or ping. thats something in the stack
[14:20] sustrik	hm, possibly
[14:20] sustrik	i would still rather refrain from connecting to 0.0.0.0
[14:21] th	totally
[14:22] th	probably busy there
[14:33] sustrik	no, ze listok spiatocny je za jednu cenu
[14:34] sustrik	ale miestenky si musis kupit zvlast na cestu tam a zvlast na cestu spat
[14:34] sustrik	aspon myslim
[20:47] mwieher	hi... quick question, whats the fastest i could fit together a 0mq system... 5k messages/sec, 20k/sec?
[20:48] guido_g	http://www.zeromq.org/area:results
[21:12] staylor	is it possible to duplex pub/sub sockets so that I can both send/recv data on a single port?
[21:14] whack	staylor: I don't think so, though I think some folks are working on a 'super socket' that will let you bind multiple zmq sockets to a single port
[21:15] staylor	alright thanks
[21:15] whack	I don't know what the status of that experiment is, I think Pieter was working on it last I heard - though I haven't payed too much attention
[21:34] Zenethian	Is there any functionality similar to DEALER/ROUTER but for PUSH/PULL? Or do I have to manually create a queue for PUSHed messages?
[21:34] Zenethian	my consumers never need to reply, so using a queue doesn't make a lot of sense. I just end up sending a garbage reply back.
[21:34] Zenethian	when using a queue device, that us
