[Pharo-project] Automatic testing in different images
by Martin Dias Sept. 28, 2010

Sept. 28, 2010

Hello, I'm working on a prototype for binary serialization of objects, and I would like to do tests and benchmarks for serializing on a stream in one image and de-serialize them in another, maybe with different conditions (other version, VM, etc). Could you recommend me how to do that in an automatic way? Thanks Martin

"Mirrors and copulation are obscene, for they increase the numbers of mankind." -- ( Jorge Luis Borges "TlÃ¶n, Uqbar, Orbis Tertius") Another point of view of course is that identity actually shows the one main weakness of mirrors.

I just wanted to show that the current method doesn't really save much. Unifying the literals in the image is dangerous, because literal strings are not immutable (and they shouldn't be IMHO). + 10 I would love to have immutability bit. > So that could lead to random errors if a method is modifying a shared string literal. This can of aliasing is bad, it mixes semantics and implementation. I hope that we will be able to fix that with Opal. Stef

The problem is that I load the package Glorp and just after loading, I do a "changes" in the MC Browser and I see a lot of classes with a lot of changes and all of them like "revison changed".

And you will see :) May be the image used to save the package got a problem and changed the timestamp of the methods.

Re: [Pharo-project] [Pharo-users] Breakpoints in Pharo

Thanks for this feature, is really useful. I've just checked latest OB where this should be integrated. I saw a "toogle breakpoint". You area talking about, aren't you? In addition, it would be nice to have such think also in the context menu in the code panel. So you don't need to go to the method and right click there. cheers Mariano On Mon, Sep 20, 2010 at 8:11 PM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr > wrote: > Did you see that there was a breakPoint class and BreakPointManager? > > Stef > > On Sep 20, 2010, at 12:14 PM, S Krish wrote: > > > > http://skrishnamachari.wordpress.com/2010/09/20/debugger-point-in-pharo-cod… > > > > Unit tests from the browser do this automatically for now.. > > > > Any corrections and inputs are welcome.. it will help in becoming that > bit more productive on Pharo.. > > > > -Skrish > > _______________________________________________ > > Pharo-users mailing list > > Pharo-users(a)lists.gforge.inria.fr > > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-users > > > _______________________________________________ > Pharo-users mailing list > Pharo-users(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-users >

Hello all, What is the state of sound in Pharo? On Linux? I can solve my current problem in various ways, including saving .wav files and playing them elsewhere, but options are always good. Bill
