visualizing is brianhauer_'s department

although I'll probably have to up the sampling frequency for any pattern recognition stuff, 1 sample per second is a bit slow for detecting things like CPU bottlenecks

FrameworkBenchmarks/master 89da119 Mike Smith: Merge pull request #1177 from TechEmpower/1172...

neat

I'm doing things!

I need to spin up an ubuntu12 vm to figure out why everything is busted

example: https://travis-ci.org/TechEmpower/FrameworkBenc...

"cowboy is busted" - that log

but when I run it on my ubuntu14 hardware, it works perfect

yay!

it's like... rebar.beam is the compiled... majig

TE-msmith: Our vagrant setup can spin up an ubuntu 12 image for you, if your line endings stuff is resolved

and you know it's not!

lol

;-)

sooooooo

Loading of /home/travis/build/TechEmpower/FrameworkBenchmarks/frameworks/Erlang/cowboy/rebar/rebar/ebin/rebar.beam failed: badfile

...yeah, that's gibberish

how did it come up with that file?

yeah, okay, this is (again) the problem that rebar is built on ubuntu14 and we're testing with ubuntu12

....SHOOOOOULD we make this another depends?

fw_depends erlang rebar

et

can you update rebar.sh to support both 12 and 14?

or no?

I'm still confused about the whole thing

okay

got it

the version of rebar included with cowboy (wrong, should be a dependency) is built with a newer version of Erlang than exists for ubuntu12

I think we need to make rebar into a dependency and just build it manually

ok

Is it statically including a binary currently?

like, in our git repo?

yes

`rebar` is a binary file

ouch

yea I can see why that's causing issues

welcome back!

hamiltont: does fw_untar allow me to specify the output filename?

doesn't look like it

You can pass it any extra args you'd pass to tar IIRC

e.f. fw_untar foobar.tgz -C put_it_here

IIRC...

neat

FrameworkBenchmarks/master db9a10c stefano casazza: Update .travis.yml

FrameworkBenchmarks/master 962207c stefanocasazza: DO NOT MERGE

do not merge? whoops?

lol

I tested it out; seemed like it worked fine

oh, that history is from the front, not the back

weird

the Golang tests are insane

the setup is wacky

acidx: I think he's copying a convention I use :-)

If a commit does something like change .travis.yml to make it easier for me to debug, I name it "DO NOT MERGE"

helps me remember to rebase and delete it before i send a PR

meh, i merged it because yolo

hamiltont: it seems that FWROOT is always going to be ~/FrameworkBenchmarks

right?

ah

no

that's the entire ponit of FWROOT, that's it not always ~/FrameworkBenchmarks

my confusion

sorry, but that's the intent

for my setup, it will always be that value, right?

huh?

On your testing machine, that's probably true

but did you merge somethign into master that hardcodes that?

no

ah ok

I misunderstood something you said a while ago

sorry, had me worried

I THOUGHT it was supposed to be ~/FrameworkBenchmarks/frameworks/[lang]/

Ohhh

so I could always do something like $FWROOT/revel

(cannot do this)

Ok, my bad. Misunderstood you

honestly though

help me with the $GOPATH stuff

it makes no sense

Yea, you cannot. Need to use $FWROOT/frameworks/lang/etc

yeah, that's fine

Dude I had the *same* problem

I tried to fix go

got lost with gopath too

I've got a bunch of go frameworks working

it doens't seem to work like it claims

falcon's busted forever (might remove it because no one is maintaining it)

RIGHT?

here's some err output: /home/techempower/FrameworkBenchmarks/frameworks/Go/revel/src/bin/benchmark (from $GOPATH)

but I `print os.environ["GOPATH"]` before that line and it spits out: /home/techempower/FrameworkBenchmarks/Go/revel/

so... it's looking in $GOPATH/src/bin ?

(it's looking for `benchmark`)

why would it do that!?

and from that link I just sent, it says

The source for a package with the import path "X/Y/Z" is in the directory $GOPATH/src/X/Y/Z

The binary for a command whose source is in $GOPATH/src/A/B is $GOPATH/bin/B

LIES GOLANG

LIES

looking to see if I spot anything

ALL LIES

it has the same layout there

what's the deal?

Apparently I made the bash_profile for the main Go/go framework - https://github.com/TechEmpower/FrameworkBenchma...

yeah, that's wrong

lol

but I don't think I set GOPATH correctly there, seems like it should be export GOPATH=$TROOT

(what's TROOT?)

TROOT = $FWROOT/frameworks/lang/your-test

nice

yes

exactly that

I think

I'm working on that

didn't know TROOT was a thing

e.g. /home/techempower/fwbm/go/revel

Yea, these vars need docs. Sorry bro

s'okay bro

you've helped so much that I will bench the knee to these ones

FIXED IT

YAY!!!

ha ha really?

sick, that was fact

yar

fast*

i've been working on them

lol

'synergy'

indeed
