that was Linux to FreeBSD though, I'm just testing Linux to Linux to see if the graph changes
|
|
[03:02] Steve-o
|
the goal is to find out if anything special is causing Windows performance to be ass
|
|
[03:06] doug
|
what are you measuring?
|
|
[03:07] doug
|
and what makes you think it might be in your critical path?
|
|
[03:08] Steve-o
|
I send a packet from one host to another, which then sends it back, I'm measuring the latency from the first second to the last receive
|
|
[03:08] Steve-o
|
I'm trying to rule out all controllable issues that can affect the critical path
|
|
[03:10] Steve-o
|
performance testing is always overly subject to errors in the testing method and framework
|
|
[03:11] Steve-o
|
you always get developers complaining they cannot achieve reported performance figures, etc

|

mikko: yes
|
|
[08:13] sustrik
|
HP-UX is broken in this respect
|
|
[08:14] sustrik
|
IIRC

mato may know more

Hi. I'm trying to use Erlang 0mq plugin on Mac OS X, but the build fails. It seems that the C driver needs to be built as a bundle rather than a dynamic library.
|
|
[09:10] demmonoid
|
The problem is that all 0mq libraries are built as dynamic libraries as well
|
|
[09:10] demmonoid
|
Is there a way to work this out?
|
|
[09:16] sustrik
|
demmonoid_: there are some OSX related issues in the bug tracker
|
|
[09:16] sustrik
|
have a look there
|
|
[09:20] demmonoid
|
sustrik, yes, I saw them but they are like 3 months old and with no response...
|
|
[09:21] demmonoid
|
To be more exact, one of them is still with no response, just that I described here...
|
|
[09:22] sustrik
|
well, you can try to fix the problem yourself then
|
|
[09:26] demmonoid
|
That's what I've tried to do but it looks like 0mq doesn't work when it's libraries are just build with -bundle instead of -dynamiclib :)
|
|
[09:26] demmonoid
|
*its libraries
|
|
[09:32] mikko
|
sustrik: but that deletes the -g -O2 flags as well
|
|
[09:33] sustrik
|
mikko: probably a bug
|
|
[09:34] sustrik
|
i have no idea about how the build system works though
|
|
[09:35] sustrik
|
demmonoid_: what exactly is the problem, does if fail? what's the error?
|
|
[09:35] mikko
|
sustrik: i got a couple patches coming soonish
|
|
[09:36] sustrik
|
mikko: ok
|
|
[09:36] mikko
|
sustrik: is there a reason why i cant send pull requests in github?
|
|
[09:36] mikko
|
would make the development flow a bit more fluent
|
|
[09:36] sustrik
|
matter of process
|
|
[09:36] sustrik
|
we should do it in a well defined way
|
|
[09:36] sustrik
|
pull requests are problematic for people on exotic platforms
|
|
[09:37] mikko
|
why is that?
|
|
[09:37] sustrik
|
NO GIT
|
|
[09:37] mikko
|
if they come through github
|
|
[09:37] sustrik
|
no git
|
|
[09:37] sustrik
|
you need git client though
|
|
[09:37] mikko
|
you need a git client to format-patch as well
|
|
[09:37] sustrik
|
all you need is diff
|
|
[09:38] sustrik
|
patches don't have to be strictly formatted
|
|
[09:38] sustrik
|
just and diff and a sign-off
|
|
[09:43] demmonoid
|
sustrik, it gives the error "i686-apple-darwin10-g++-4.2.1: -compatibility_version only allowed with -dynamiclib" upon build
|
|
[09:46] demmonoid
|
I removed this flag from libtool, as well as install_name which is also incompatible with -bundle
|
|
[09:46] demmonoid
|
Will see if this works
|
|
[09:46] mikko
|
demmonoid_: osx build for erlzmq is broken?
|
|
[09:47] demmonoid
|
Yes, it is
|
|
[09:47] demmonoid
|
Looks like it's broken for OS X for a long time...
|
|
[09:48] demmonoid
|
At least for Snow Leopard
|
|
[10:02] demmonoid
|
So, I rebuilt 0mq with -bundle, edited erlzmq's configs so it will compile with -bundle instead of -dynamiclib, but I still get the same error: "i686-apple-darwin10-g++-4.2.1: -bundle not allowed with -dynamiclib"
|
|
[10:02] demmonoid
|
It appears that zeromq libs were built with -dynamiclib anyway
|
|
[10:03] mikko
|
sustrik: i added --enable-debug flag to builds
|
|
[10:03] mikko
|
sustrik: do you think something like this is useful?
|
|
[10:06] mikko
|
as currently it's not possible to really set debug flags
|
|
[10:07] mikko
|
-O2 will be in the build line in any case
|
|
[10:07] sustrik
|
what I do is:
|
|
[10:07] sustrik
|
export CXXFLAGS="-g -O0"
|
|
[10:07] sustrik
|
./configure --disable-shared
|
|
[10:07] mikko
|
you need to do CPPFLAGS and CFLAGS as well, if building with pgm
|
|
[10:08] sustrik
|
right
|
|
[10:08] mikko
|
for normal user maybe ./configure --enable-debug might be easier
|
|
[10:08] sustrik
|
right, you want to merge all three into s single flag
|
|
[10:08] sustrik
|
1. -g
|
|
[10:08] sustrik
|
2. -O0
|
|
[10:08] sustrik
|
3. --disable-shared
|
|
[10:09] mikko
|
i will look into adding --disable-shared as well
|
|
[10:09] sustrik
|
it helps
|
|
[10:09] mikko
|
the problem is that i am not 100% convinced if this is really needed
|
|
[10:09] mikko
|
as for example with sun studio the debug flag is -g0
|
|
[10:09] sustrik
|
as if it's not set, the tests are built with a different name
|
|
[10:10] sustrik
|
and then there's a wrapper script to launch them
|
|
[10:10] sustrik
|
thus launching it within bebugger
|
|
[10:10] sustrik
|
actually debugs the shell
|
|
[10:10] sustrik
|
not the test program
|
|
[10:10] sustrik
|
mikko: i would appreciate it
|
|
[10:10] sustrik
|
it saves some time when debuging
|
|
[10:12] mikko
|
sustrik: ok, will add

anybody seeing this assertion failure against latest master?
|
|
[19:08] cremes
|
Assertion failed: !more || pipes [current] != pipe_ (fq.cpp:61)
|
|
[19:09] cremes
|
i'm trying to get a small reproducible case but have so far been unsuccessful
|
|
[19:09] cremes
|
would a backtrace be useful in the absence of reproducible code?
|
|
[19:27] sustrik
|
cremes: yes, back trace is always helpful
