First shot on acceptance tests for the VM
by Guillermo Polito June 23, 2013

June 23, 2013

Hi! We were discussing over here about it, so I decided to finally start something on the front of an acceptance test for our VM. The core idea is to stress the VM to test its stability and find bugs and regressions. So I created the ci job in [1] which does: - use latest vm - use 2.0 latest image - loads seaside and moose on it - runs all tests Right now it runs on 6 different slaves, getting different results on each, which we should take care about :). Also there are some things on it that should be improved easily: - once 2.0 summer is released this job should use that version instead of the "latest" 2.0 - right now we are loading the development version of moose because moose 4.8 is not released (but will be soon :) And of course, now we have them, we can improve them (and make them run because not all of them do :D).

Cloud Hosting Tip
by Sven Van Caekenberghe June 21, 2013

June 21, 2013

Hi, I am a fan of Amazon AWS's Cloud Services. But it is not perfect. Enter Digital Ocean (https://www.digitalocean.com) an easier to use, simpler cloud hosting provider, that is cheaper and seems faster. You get a raw machine, so you still need some basic Unix admin skills, but apart from that it cannot get much easier. For just $5 a month you get this: As an SSD based machine, it feels very fast. I did some quick benchmarks at the Pharo level which show that this virtualised hardware is up to 10x faster than an Amazon AWS EC2 micro instance, and up to 3x faster than an Amazon AWS EC2 small instance. Its just a bit slower than my top of the line MacBook Air: root@stfx:~# ./pharo Pharo.image eval '1 tinyBenchmarks' '764749813 bytecodes/sec; 94679619 sends/sec' To get started on the empty machine, just do root@stfx:~# curl get.pharo.org/30+vm | bash If you picked a 32 bit Ubuntu, you only need to do root@stfx:~# apt-get install libssl0.9.8 Starting a Zn server is dead easy: root@stfx:~# ./pharo Pharo.image eval --no-quit 'ZnServer startDefaultOn: 1701' & Have a look at: http://82.196.12.54:1701 Which is a single vm+image instance. Local network performance is quite good: root@stfx:~# ab -k -n 1024 -c 4 http://localhost:1701/bytes Server Software: Zinc Server Hostname: localhost Server Port: 1701 Document Path: /bytes Document Length: 64 bytes Concurrency Level: 4 Time taken for tests: 0.584 seconds Complete requests: 1024 Failed requests: 0 Write errors: 0 Keep-Alive requests: 1024 Total transferred: 243712 bytes HTML transferred: 65536 bytes Requests per second: 1753.68 [#/sec] (mean) Time per request: 2.281 [ms] (mean) Time per request: 0.570 [ms] (mean, across all concurrent requests) Transfer rate: 407.59 [Kbytes/sec] received I also tried a big config based build that downloaded and compiled about 1Gb worth of .mcz and that took less than 4 minutes which is also quite fast. Of course, you get way fewer features than with Amazon AWS (the total ecosystem). But for the price it seems hard to beat. Have fun !

Running tests from Nautilus
by Alexandre Bergel June 21, 2013

June 21, 2013

Hi! Test method of a superclass are not run within Nautilus. Consider: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= TestCase subclass: #ATest. ATest compile: 'test self assert: false'. ATest class compile: 'isAbstract ^ self name == #ATest'. ATest subclass: #BTest. BTest compile: 'test2 self assert: true'. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Selecting BTest in Nautilus and pressing Alt-t says BTest is green. The test runner rightfully says otherwise. We had some yellow test in Moose because of this :-) I have tried to enter a bug issue on https://pharo.fogbugz.com but I could not. In 2 minutes I could not figure out how to create a login and how to see the list of existing bugs. So maybe this one has already been reported. Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
