Are ipc:// URIs expected not to work under Windows? We are getting a "Protocol not supported" error when trying to bind to "ipc://listener".
|
|
[02:11] amacleod
|
Ah.. there it says right in the manpage. It's currently only implemented on OSs that provide UNIX domain sockets.

hello, i was wondering if I could get some assistance trying to figure out some difficulty I'm havnig with multithreaded code...
|
|
[03:03] brazilnut000
|
basically, I'm spawning a thread to subscribe to incoming data and update some variables while my main thread does some other stuff (including talk on other ports)
|
|
[03:03] brazilnut000
|
they're both using the same context, but my thread doesn't seem to get anything from the publisher
|
|
[03:04] brazilnut000
|
however, if i make the same calls to create, bind, and subscribe in my main thread it works...
|
|
[03:05] brazilnut000
|
anyone?
|
|
[03:24] brazilnut000
|
hrmm...i guess not...
|
|
[03:25] Steve-o
|
morning all, looks like o'reilly doesn't actually archive webcasts?
|
|
[03:32] amacleod
|
brazilnut000, you are not sharing sockets between threads, are you? Just contexts?
|
|
[03:32] amacleod
|
brazilnut000, what transport are you using, and what ZMQ pattern?
|
|
[03:39] brazilnut000
|
oh, sorry, stepped away.
|
|
[03:40] brazilnut000
|
I'm sharing contexts only, tcp, ZMQ_PUB and ZMQ_SUB
|
|
[03:44] amacleod
|
Ok. So you shouldn't need to be messing with any addressing/routing.
|
|
[03:44] amacleod
|
How many I/O threads? 1?
|
|
[03:44] brazilnut000
|
1
|
|
[03:47] amacleod
|
Dunno. Is it possible that the subscriber is trying to connect before the publisher has had a chance to become established?
|
|
[03:48] amacleod
|
(I'm not sure how timing issues are supposed to work with PUB/SUB.)
|
|
[03:50] brazilnut000
|
it's possible, though unlikely....also, as I understand it, order shouldn't matter. It's possible to lose the first 'x' messages, but I don't ever get any...
|
|
[03:56] brazilnut000
|
well, thanks for giving it a shot. Gonna go get some dinner...
|
|
[03:57] amacleod
|
You're welcome. Sorry I couldn't get any further.

sustrik: g'morning

[07:44] sustrik
|
morning
|
|
[07:44] pieterh
|
just curious if you found that leak yesterday
|
|
[07:45] sustrik
|
well, i found one delayed deallocation
|
|
[07:45] sustrik
|
but afaics it applies only to sockets with no connects/binds
|
|
[07:45] sustrik
|
so it's probably a different issue
|
|
[07:46] pieterh
|
a'ight
|
|
[07:46] sustrik
|
anyway, i'm patching it now
|
|
[07:50] sustrik
|
pieterh: the master documentation doesn't seem to be updated automatically
|
|
[07:50] sustrik
|
should it?

pieterh: the patch is in master
|
|
[08:01] sustrik
|
can you check whether the leak persists?
|
|
[08:01] sustrik
|
just in case...
|
|
[08:18] pieterh
|
sustrik, re
|
|
[08:19] pieterh
|
master docs are not yet updating automatically, but I'll check with mikko, everything is ready for that
|
|
[08:19] pieterh
|
i'll check the leak later, need to use a different box (multicore)
|
|
[08:21] sustrik
|
ok
|
|
[08:21] pieterh
|
though in the test case, sockets were definitely being used (recv) and closed systematically
|
|
[08:52] pieterh
|
sustrik: good news
|
|
[08:52] pieterh
|
as far as I can tell from initial tests, you've fixed the leak
|
|
[08:52] sustrik
|
interesting
|
|
[08:53] pieterh
|
I'm doing more tests now
|
|
[08:54] pieterh
|
I retract that
|
|
[08:54] pieterh
|
it works over inproc but not over tcp
|
|
[08:55] pieterh
|
and I think inproc was getting weird test results if run after tcp
|
|
[08:55] pieterh
|
cremes' original test case still leaks memory (and consumes a whopping amount of CPU)
|
|
[09:05] sustrik
|
ok
|
|
[09:23] pieterh
|
do we have an open issue for this?
|
|
[09:23] pieterh
|
i've stripped down chuck's test case and would like to post that somewhere
|
|
[09:27] sustrik
|
no idea
|
|
[09:27] sustrik
|
there's none unless chuck opened one
|
|
[09:28] pieterh
|
ok
|
|
[09:28] pieterh
|
I'll ask him to do so
|
|
[09:30] pieterh
|
hmm, back with 'too many open files'... strange
|
|
[09:31] sustrik
|
well, the test case is creating undetermined number of sockets
|
|
[09:32] pieterh
|
yes, it's a fault in my test case
|
|
[09:34] pieterh
|
ok, I need to leave for a while bbl
|
|
[12:03] mikko
|
ian did well
|
|
[12:14] cremes
|
pieterh, sustrik: i opened a ticket on this leak a few days back: https://github.com/zeromq/zeromq2/issues#issue/171
|
|
[12:14] cremes
|
example code is in a gist attached to the ticket
|
|
[12:14] cremes

brb...
|
|
[12:25] sustrik
|
mikko: you've been on the coference?
|
|
[12:26] sustrik
|
there's a lot of tweets about the lecture
|
|
[12:28] sustrik
|
hi ian
|
|
[12:28] sustrik
|
how did it go?
|
|
[12:30] mikko
|
sustrik: here at the moment
|
|
[12:30] sustrik
|
no haste
|
|
[12:30] ianbarber
|
hey! pretty good i think
|
|
[12:31] sustrik
|
people seem to be happy according to twitter
|
|
[12:31] sustrik
|
any feedback, questions?
|
|
[12:32] mikko
|
http://joind.in/talk/view/2523
|
|
[12:32] mikko
|
there is some feedback already
|
|
[12:34] sustrik
|
nice :)
|
|
[12:36] ianbarber
|
good comments, had some questions about persistance, telehash, whether it could run on an arduino, some zero vs activemq stuff, and a bit on whether you can do pgm on ec2
|
|
[12:38] sustrik
|
good question
|
|
[12:39] sustrik
|
especially the last one :)
|
|
[12:39] sustrik
|
i have to admit i have no idea
|
|
[12:41] ianbarber
|
me either :) the next talk was about ec2 though, so that's handy
|
|
[15:56] mikko
|
pieterh: here?
|
|
[15:56] pieterh
|
hi mikko, yes
|
|
[15:56] mikko
|
should i run apiall or apione in the docs builds?
|
|
[15:57] pieterh
|
apiall, that's the main script
|
|
[15:58] pieterh
|
sorry...
|
|
[15:58] mikko
|
hmm
|
|
[15:58] mikko
|
ZMQ_DIR seems to have changed as well
|
|
[15:58] pieterh
|
I've made apiall do the whole job
|
|
[15:58] pieterh
|
there is no ZMQ_DIR any more
|
|
[15:59] pieterh
|
apione is to update a single version from some repository
|
|
[15:59] pieterh
|
does this make sense?
|
|
[16:00] mikko
|
yes, ill check the code to see what exactly is happening
|
|
[16:01] mikko
|
so it expects to find ../../zeromq2 ?
|
|
[16:01] pieterh
|
yes
|
|
[16:01] pieterh
|
and ../../zeromq2-1
|
|
[16:01] mikko
|
and ../../zeromq2-1
|
|
[16:01] mikko
|
ok
|
|
[16:01] pieterh
|
and eventually ../../zeromq2-0 when we make that
|
|
[16:01] pieterh
|
etc.
|
|
[16:02] pieterh
|
does that match how you use the repos on the build system?
|
|
[16:02] mikko
|
no, this far i've used branches
|
|
[16:02] mikko
|
i think i need to update all maint builds at some point
|
|
[16:02] pieterh
|
right, but the relative locations of ztools and zeromq2
|
|
[16:03] mikko
|
ah, thats different as well
|
|
[16:03] mikko
|
but i can make it to use the new structure
|
|
[16:03] pieterh
|
let me know if you need any changes to the apisite stuff, happy to do whatever's needed
|
|
[16:03] mikko
|
i wonder if git submodules would make sense here
|
|
[16:04] mikko
|
they are a bit like svn externals
|
|
[16:05] pieterh
|
oh, that gets really complex real fast, mikko...
|
|
[16:05] ianbarber
|
i've heard they are often a bit of a pain
|
|
[16:05] mikko
|
i meant using submodules in this way:
|
|
[16:06] mikko
|
ztools/apisite/source/master -> zeromq/zeromq2/master
|
|
[16:06] mikko
|
when you checkout ztools you can recursively take submodules if you want
|
|
[16:06] mikko
|
and if not then you can put the code into right place
|
|
[16:07] mikko
|
not sure how jenkins handles that
|
|
[16:07] mikko
|
because currently jenkins is configured to use zeromq/zeromq2 as source repo for docs build
|
|
[16:07] mikko
|
and it polls that repo for changes and builds if changes are detected
|
|
[16:08] mikko
|
i'll look into this as soon i can get onto a bit faster internet
|
|
[16:08] mikko
|
conference wireless is a bit painful
|
|
[16:14] pieterh
|
hmm
|
|
[16:18] pieterh
|
ok, I've made a PHP version of the Guide, http://zguide.zeromq.org/php:all
|
|
[16:23] sustrik
|
pieterh: some of the examples are in python and c++
|
|
[16:25] sustrik
|
and c
|
|
[16:30] pieterh
|
only the very first ones, deliberately
|
|
[16:30] pieterh
|
and some fragments here and there which are never translated
|
|
[16:31] pieterh
|
this is still experimental, I'm sure we can improve it, but I don't want to have to modify the text itself to make a language-specific version
|
|
[16:31] pieterh
|
my idea is that any language which hits 100% gets its own version
|
|
[16:32] sustrik
|
ok
|
|
[16:59] lt_schmidt_jr

hi

hi
|
|
[22:07] apexi200sx
|
anyone got any use cases for zeromq
|
|
[22:08] cordor
|
is there precompiled version somewhere?
|
|
[22:11] sustrik
|
condor: there are snapshots
|
|
[22:12] sustrik
|
apexi200sx: there were few use cases mentioned on the mailing list
|
|
[22:13] cordor
|
zeromq-2.0-alpha1.exe?
|
|
[22:14] siggimoo
|
apexi200sx: we're using ZeroMQ for network monitoring. Individual processes monitor something and push their readings to a central analyzer, which in turn publishes its findings to zero-or-more subscribers, one of which is a pager/alarm system.

Hello #zeromq. Could 2.1.1rc1 be tagged in git? It would be handy for those of us tracking git to know what is considered stable-ish
|
|
[22:35] erickt
|
oh, look at that, I guess 2.1 has been forked into it's own repository
|
