[Pharo-project] SUnit Time out
Hi guys in Squeak andreas introduced the idea of test time out Do you think that this is interesting? Stef SUnit - All test cases now have an associated timeout after which the test is considered failed. The purpose of the timeout is to catch issues like infinite loops, unexpected user input etc. in automated test environments. Timeouts can be set on an individual test basis using the timeout: seconds tag or for an entire test case by implementing the #defaultTimeout method. ___ Pharo-project mailing list Pharo-project@lists.gforge.inria.fr http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project

[Pharo-project] How do I install seaside in Pharo 1.0?
Hello, I have problem installing Seaside on Pharo 1.0. Evaluate ConfigurationOfSeaside workspace did not work. I have also tryed this code: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfSeaside'; load.

Re: [Pharo-project] SUnit Time out
Stef, Time to expose some of my ignorance (don't worry, I have plenty more waiting where I found this): what is the tag concept? That sounds very Tweak-ish, and I am a real believer in doing things with the language, not TO the language whenever possible. That is not to say that frameworks are bad; in fact, it means that frameworks are good, language extensions are anywhere from suspect to evil. I have some code that I am still porting, but the basic idea is to be able to write [ code that might not complete ] tryForSeconds:10 onTimeOut:[ ]. With a robust capability to do such things, it is probably not necessary (or even appropriate) for TestCase to enforce timeouts. The timeout block can simply raise an exception or assert false, and there is no need to disable timeouts where they do not belong.

[Pharo-project] trait composition conflict autoresolution
Hi all, I'm doing some work with traits, and I found something like this
case:
Trait T1m1
^self requirement
Trait T2m1
doSomeStuff
Class C1 uses: T1 + T2
[note, i'm not excluding m1 from T1 in the T1 + T2 composition.]
And the resulting:
C1m1
doSomeStuff
It is just ok, since the other m1 is just a mark for a requiredMethod, but I
find this a little weird, since do not follow the Trait definition. (at
least the one I read, maybe it changed!). Wouldn't be better to
automatically add the exclusion at the composition?
Class C1 uses: T1 - {#m1} + T2
In this way the definition would be followed without any exception (and it
will be explicit with what is going on). This is just a suggestion, anyway
it works great!
btw... why there are two requirement marks?:
Objectrequirement
self error: 'Implicitly required method'
ObjectexplicitRequirement
self error: 'Explicitly required method'
the question is, if I use #requirement, I'm explicitly requiring that
method. Is there any situation where I should use #requirement?
Cheers

For me the point is that I have the impression that this is an interesting feature to have when we have a test server.

not really. Or this means that the composition algo does not work well.
Now since C1 redefined m1 in both cases you will have Cm1 taking precedence
over T1m1.
I already forget but I discussed with tom and in javascript it proposed a
different one
than the ones we have in smalltalk and it was coherent too.
Now there is a bug in pharo and squeak3.9 because if C1 is in fact the
superclass

fullfiled or something like that.]

[Pharo-project] [ANN] Camp Smalltalk London filling up
Much to our delight, there seems to be a lot of interest in the Camp Smalltalk event in London. We originally estimated our capacity at 30, and those slots have already filled up in less than 4 days! We are just now discussing what our actual maximum capacity is. We'll be able to handle a few more people, we're just now sure yet how many. So if you're interested in coming and haven't signed up yet, please head over to cslondon2010.eventbrite.com and add yourself to the waiting list. That will really help us understand how many more people still want to attend. Note that joining the waiting list does not commit you to attending, so if you're still on the fence, you might want to sign yourself up anyway. We'll open up some more spots next week and then see how it goes. Thanks for your enthusiastic participation!

different one
than the ones we have in smalltalk and it was coherent too.
Well, what I tried to say is that C1 do not redefine m1, it gets T2m1
from the T1 + T2 composition.
So, is there a conflict if I compose T1 + T2 and do not redefine m1 in the
composition client?
Or is this improvement OK? (explicit required methods do not produce
composition conflicts),
since having a conflict between a real message implementation and a
explicitRequirement marked message doesn´t make any sense
Now there is a bug in pharo and squeak3.9 because if C1 is in fact the
superclass
of the class using the trait then the requirement is not considered as
fullfiled or something like that.]
Do you mean that should be expected that a trait's required method
shouldn't hide a superclass implementation for that message?
All my doubts about this issue are actually one: does a trait's required
method any special behavior with respect to the composition (conflicts
with equals named messages in the composition, overrides equals named
messages in the composition's client superclass, etc), or these messages
behave exactly like any other message?
