Re: [Pharo-project] bug in Nautilus/RPackage?

by Alexandre Bergel

Hi! I took a fresh 1.3 image, and do it the following: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Gofer new squeaksource: 'Spy'; package: 'ConfigurationOfSpy'; load. (Smalltalk at: #ConfigurationOfSpy) project lastVersion load. Gofer new squeaksource: 'Nautilus'; package: 'ConfigurationOfNautilus'; load. (Smalltalk at: #ConfigurationOfNautilus) project lastVersion load -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= I see the packages Spy, Spy-Core, .... Clicking on Spy-Core raises an error: Does not understand NautilusUI>>historyChanged. Below the pharo debug file When I load Nautilus first then Spy, only an empty Spy package appears in the browser with: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Gofer new squeaksource: 'Nautilus'; package: 'ConfigurationOfNautilus'; load. (Smalltalk at: #ConfigurationOfNautilus) project lastVersion load. Gofer new squeaksource: 'Spy'; package: 'ConfigurationOfSpy'; load. (Smalltalk at: #ConfigurationOfSpy) project lastVersion load. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= I am ready to push Nautilus.

[Pharo-project] ChangeSet changedMessageList broken

by Stefan Marr

Hello: The following example is broken: ChangeSet new commentClass: ChangeSet; changedMessageList It will raise an exception that no #Comment message was found in the ChangeSet class. (BTW: the key not found error does not name the key, which is rather inconvenient) The reason seems to be a change in ChangeSet>>#changedMessageList. The change is tracked as being done by Benjamin Van Ryseghem (11/6/2010 22:11) and seems to switch from MethodReference to SourcedMethodReference, which breaks the example. Does anyone know the intention or context of this change? Is it possible to revert to Marcus' pervious version of that method? A test for this bug could be the lines of: testChangedMessageListAndComments | changeSet | changeSet := ChangeSet new. changeSet commentClass: ChangeSet. self assert: 1 equals: changeSet changedMessageList size. self assert: ((changeSet at: 1) isKindOf: MethodReference). self assert: #Comment equals: (changeSet at: 1) methodSymbol.

Why this defensive approach to code that adds duplicate entries to a menu? Why not avoid the duplicated entries from being added to begin with?

I have done that recently with ci.moosetechnology.org. I just deployed jenkins.war where hudson.war was, changed the script to point to it, and everything was fine.

Re: [Pharo-project] The Cult of Done Manifesto

by Norbert Hartl

Am 21.05.2011 um 02:40 schrieb Andres Valloud: > Statements like "just pretend you know what you're doing" should raise red flags because it leads to "doing anything at all, even it is bad, is good". One might as well forget trying to know in favor of pretending to know, because doing something (anything) makes you right. But of course, no amount of pretense will make software work when it's critical for it to work at a customer's site, or when doing a demo of your research work while defending your thesis. Not only that, but doing something any which way has the hidden cost of incurring into software debt. Exactly how much cleanup homework are we still dealing with because of that kind of attitude? Are we happy with the results? Things that Work(TM) don't happen by accident, they are the product of significant amounts of effort. Shoddy code that appears to work some of the time is Just Bad(TM), and sooner or later you pay for it ***with interest***. > I don't read an imperative in that rule that you should pretend. I read it in a way that "not knowing it exactly" shouldn't keep you from doing things. There is no apriori experience. So we often don't know exactly what we do but we learn it while doing it. You might think you know what you are doing and you will learn a lot while you are doing it. At the end you will look back to the point when you started and what you think might by that you were some kind of pretending at the beginning. We are as incremental in learning as our software is in being created. IMHO the term "doing it right" is omnipresent in software development and often leads in the wrong direction. I think I suffered more from that so far as from pretending colleagues. my 2 cents, Norbert > On 5/18/11 4:17 , Marcus Denker wrote: >> The Cult of Done Manifesto >> >> - There are three states of being.
