[Pharo-project] SUnit
by Adrian Kuhn April 6, 2010

April 6, 2010

Niko and me are thinking about doing some work on SUnit. Background is that we are working on Phexample, which extends SUnit with test that expand on one another [1]. We got test dependencies working with the current SUnit, but had to do some quick ugly hacks. So we thought about cleaning the internals SUnit up, and then include test dependencies in the core. Things we would possible change (we will certainly identify more as we clean up SUnit...) - store test resources in a dynamic variable rather than a static one - refactor the assert: protocol to a trait, such that they can be used in setup and teardown of test resources as well (actually I already did that, you can find a version on my squeaksource account) - apply the fixes to test resources in Niall's slide deck that Lukas showed us - add expectations matchers as used in behavior-driven testing - break testcase into two classes, and to run the test and one to store the result (no more #cleanUpInstanceVariables hack to avoid memory leaks) - add test dependencies to test results, such that one test can extend on the return value of another test - fix expected failures such that they are a first-class result (no more #shouldPass with O(n^2) or worse behavior) So you see, the idea is twofold: first to clean up what is there, and second to add test dependencies as a new feature. For those that dont know test dependencies. They had first been proposed by Markus GÃ¤lli based on an analysis of all Squeak tests years ago. He found that most tests cover a superset of another test's coverage set. A prototype in Java as been implemented later by Lea HÃ¤nsenberger and me. We published a case study at XP 2008, which lead to PHP folks to include test dependencies in the latest PHPUnit. The idea of explicit test dependencies is to shift the burden of isolating test cases from the developers to the framework. You avoid duplicate test code and you get less red test cases per failure. Please refer to Niko's blog post for more details [2]. We got some more ideas (such as API baseline testing, search in test results, etc...) but they will not likely make it into a first clean up. One thing we do not know is how many folks are out there that depend on internal representation of SUnit. I talked to some folks and identified two requirements, first that legacy tests should keep running and second that contributions to other sunit forks should keep being mergeable. The first seems feasible, the second sounds like it boils down to not cleaning anything :) What do you think? cheers, AA [1]: http://www.squeaksource.com/phexample.html [2]: http://smalltalkthoughts.blogspot.com/2009/11/phexample-because-examples-ex…

[Pharo-project] Handle Close Event in Image - necessary for 1.0?
by Torsten Bergmann April 6, 2010

April 6, 2010

>open a ticket As I wrote, there is an issue 2131 already. >provide some tested code I can just provide an old changeset mixed up from Squeak code - it works but I do not have tested or look if it merges correctly with Pharo. At least it works, I dont like the "TheWorldMenu basicNew quitSession" hack. Someone (with knowledge of the event handling system) should review or enhance it (Marcus?). You will find it attached. >I cannot do everything especially for platform I do not have access to. We should handle this in-image now for all platforms since it is AFAIK this is now supported by all VM's. How is it done on Mac and Linux these days? >Then, for 1.1 open a ticket so that someone try to fix the problem with the >version 4. There is already one: http://code.google.com/p/pharo/issues/detail?id=2131 If we want to keep quality high we should care about this.

[Pharo-project] FFI tests
by Schwab,Wilhelm K April 6, 2010

April 6, 2010

Hello all, Is anyone having success with the FFI tests on Linux? I have been having some weird problems with an RC1 image and noted that many of the tests fail in it. My image builder is almost ready for another attempt at making a newer image, and I will prioritize the tests. I also have an idea or two on how to try to reproduce the problems I am having. Bill

[Pharo-project] Linux VM microbenchmarks
by laurent laffont April 6, 2010

April 6, 2010

Hi, Thanks to people who send the results of tinyBenchmarks for various CPU, here's the report. What I want to know is whether these results are crap or "normal". It seems that all people succeed in compiling the VM with the source provided. So it may be a candidate for Pharo 1.0 ? The procedure to build the VM was: wget http://lolgzs.free.fr/pharo/squeak-vm/Squeak-3.11.3.2135-pharo-src.tar.gz tar -xvzf Squeak-3.11.3.2135-pharo-src.tar.gz cd Squeak-3.11.3.2135-pharo-src/ mkdir build && cd build ../unix/cmake/configure --CFLAGS="-O2" make The results: Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz 64 bits =============================================== 432 M bytecodes/sec; 13 M sends/sec Intel(R) Core(TM)2 Duo CPU T8300 @ 2.40GHz 64 bits =============================================== 424 M bytecodes/sec; 13 M sends/sec Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz 32 bits =============================================== 389 M bytecodes/sec; 10.5 M sends/sec Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz 32 bits =============================================== 330 M bytecodes/sec; 9.2 M sends/sec Intel(R) Core(TM)2 CPU 4300 @ 1.80GHz 64 bits (CFLAGS = -O3) =============================================== 331 M bytecodes/sec; 8.9 M sends/sec Intel(R) Core(TM)2 CPU 4300 @ 1.80GHz 64 bits (CFLAGS = -O2) =============================================== 106 M bytecodes/sec; 3.4 M sends/sec Intel(R) Core(TM)2 CPU 6420 @ 2.13GHz 32 bits =============================================== 220 M bytecodes/sec; 7.6 M sends/sec Intel(R) Pentium(R) 4 CPU 3.00GHz 32 bits =============================================== 93 M bytecodes/sec; 5.5 M sends/sec AMD Athlon(tm) 64 Processor 3000+ =============================================== 87 M bytecodes/sec; 4.5 M sends/sec Laurent Laffont

Smalltalk is more than just flat text in an editor, which is why Redline Smalltalk is different. I'm trying to bring out some new features that would even make die-hard Smalltalk environment users envious, and at the same time not make barriers to an uptake by more developers. > Sorry, but I believe that it is the way that had to take commercial > Smalltalk. It surprises to me that Cincom and company do not see it. Well I'd be really happy to do this full-time with Cincom support (if they are listening), and if it can remain free and open source. Cincom?

Re: [Pharo-project] How do i import .MCZ into Squeak?

Hi Pharo, I got the .MCZ package installed, but there is a dependency on RBProgramNode which I can't find. I'm looking for the package / source for RBProgramNode, which I think could just be a image version issue. Is it? Rgs, James.

The VM also includes an optimisation for Large...Integer objects, utilising Java BigIntegers as shadows. HPI students once approached a JIT compiler (not finished); the code is available by request. Best, Michael
