Added asynchronous guzzle calls

[t0k4rt]

Hi,
I just added an option to make async calls with guzzle. Should be interesting if you don't want to wait for google to respond !

Hi just to add some details about this pr,
The PR passes the tests correctly (it's an issue with travis which sometimes fails to install correctly composer dependencies)
I did some benchs, the async option is really a must have since the connection time is more than twice lower than without async calls (from 175ms to 60ms on first connection)

@krizon Actually after some tests, there is an issue, Google doesn't like this async mode :-/, I don't know why but I need to get the response to get a correct event. that's bad news :(
I guess the best way to have real async is to use a task queue,
the function "register_shutdown_function" works well but it's not real async ...

@t0k4rt i've just added a test to this branch locally to perform some real async calls to a test GA property and they seem to be logged correctly. What problems where you encountering?

[t0k4rt]

Hi,
I just checked another time to be sure, when I use in config the option 'async' => true
I get no hits in google real time view.
It could be related to a different curl version since we have the same code ?

[krizon]

Just to be sure, you test with --group=internet and you've set the correct tracking_id in the phpunit.xml(.dist)? I'll open a PR which includes test with real calls to GA. Would appreciate it if you would test that PR.

Actually I tested the lib directly in a piece of code, not with phpunit.
I just went through the tests, when you live test, the async option is by default on false.
In the test I added to the lib, I was just checking that the async plugin was well loaded.
I should write a test that test with the async option on true

@t0k4rt added the test in PR: t0k4rt#1

[t0k4rt]

I launched the new tests, I think I should have two pageview (one without asyn, one with async) , I only get one hit.

[t0k4rt]

On your side do you see 2 hits ?

[krizon]

I see:
/php-ga-measurement-protocol/phpunit-test
/php-ga-measurement-protocol/phpunit-test/async

So you're on krizon/async-request and you see the method testAsyncRequestLive? And you are viewing the following report: Real-Time -> Content -> Pageviews (Last 30 min)?

[t0k4rt]

Yes I'm on the right analytics page, I only see this one :
/php-ga-measurement-protocol/phpunit-test

[t0k4rt]

I updated my packages in case and restarted my webserver ... still nothing ...
In case, what's your config ?
I'm on linux ubuntu with nginx / php-fpm

[krizon]

CentOs with Apache/2.2.15

cURL Information => 7.19.7

[t0k4rt]

I'm on curl 7.22.0, I'm going to try with 7.19.7 version just in case.

[t0k4rt]

Actually this version of the package is not available on ubuntu, I can't try it :-/
I tried on another vm with apache2.4.9 / curl 7.22.0 but same result ...
