[Pharo-project] Pharo 1.2.1 Problems with OpenGL

by Casimiro de Almeida Barreto

In Pharo 1.2.1 it's not possible to intall OpenGL (yeah, I know, quite old code). Lots of syntax errors during install. It works in Pharo 1.1.1

Comment #4 on issue 3957 by lem...(a)gmail.com: MethodWrappers left method after uninstall http://code.google.com/p/pharo/issues/detail?id=3957 jajaja, I'm developing a aspect oriented language for Pharo, using method wrappers as a first implementation approach.

I've been grabbing and trying one-click images from Hudson for a while. They have worked on Ubuntu 9.10 and 10.04. My sampling is not exhaustive, but the Linux one-clicks seem to work. My current "project" (hopefully complete) is to eliminate my dependence on some hacks that I added to the vm. ________________________________________ From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] On Behalf Of Marcus Denker [marcus.denker(a)inria.fr] Sent: Tuesday, April 05, 2011 5:28 PM To: Pharo Development Subject: Re: [Pharo-project] Draft Pharo 1.2.1 Release Announcement On Apr 5, 2011, at 10:38 PM, Marcus Denker wrote: > > On Apr 5, 2011, at 10:28 PM, Adrian Lienhard wrote: > >> Thanks, Sven! >> >> I've put the page online >> - as a blog entry on the news page: http://www.pharo-project.org/news >> - the release page: http://www.pharo-project.org/pharo-download/release-1-2-1 >> >> (I've slightly edited some of the bullet point items to fit on one line) >> >> Thanks Laurent for the translation.

Dumb question: did we actually test the one-click on linux and win? On the mac it works, but the rest I did not test myself.

The provable best and most cost effective way to do it is: flip a coin (and that is serious, has the same or even better reliability and quality of result) If you think that is not good enough, well then the absolute minimum is something like this: - run your benchmark 5 times - 5 times with your optimization - 5 times without - look at the collected raw values i.e. measure runtime - and use your gut feeling to decide whether you have meaningful values and whether your time to do the optimization was well spent (don't eliminate outliers) If that is still to much to do, well, again, just flip a coin, and you have a high chance that the result of that are actually more reliable. (the approach above does not account for systematic errors...) However, once you got your optimization into the VM your favorite build server should do its thing and that should include performance regression testing which is using a "slightly" more sophisticated approach than the described one.
