[Pharo-project] proposed fix for issue 913
by Dale Henrichs July 3, 2009

July 3, 2009

http://code.google.com/p/pharo/issues/detail?id=913 I wasn't able to directly reproduce the problem in my tests, but upon code inspection it was obvious that an empty Dictionary should be returned by BytecodeEncoder>>blockExtentsToTempRefs instead of nil. None of the senders would be adversely affected by the change. Of course the changes are in the Compiler package, so it's worth having an extra set of eyes take a look. Dale

[Pharo-project] creation of ReadWriteStream with #on:
by Cyrille Delaunay July 3, 2009

July 3, 2009

Hi, ReadWriteStream inherits from WriteStream which hinerits from PositionableStream. When you create a ReadWriteStream with #on: you use the default definition in PositionableStream : PositionableStream class >> on: aCollection "Answer an instance of me, streaming over the elements of aCollection." ^self basicNew on: aCollection #on: is not overriden in the instance side of ReadWriteStream and therefore it's the definition of WriteStream that is called : WriteStream >> on: aCollection super on: aCollection. readLimit := 0. writeLimit := aCollection size. Put the readLimit at 0 make sense for a WriteStream ( with witch your not supposed to read ) but when you create a ReadWriteStream on a collection you would be able to read what is already in the collection, no? I wonder why #on: has not been overriden in the instance side of ReadWriteStream ? Maybe it's not a good idea to create a ReadWriteStream with a collection that already includes elements ?

[Pharo-project] oldFileNamed
by Henrik Johansen July 3, 2009

July 3, 2009

Forgetting the wish for new File accessing implementations for a moment, is there a reason why the current StandardFileStream >> oldFileNamed: (and oldFileFullyNamed) is implemented: ^(self isAFileNamed: fileName) ifTrue: [self new open: fileName forWrite: true] ifFalse: [(FileDoesNotExistException fileName: fileName) signal] instead of : ^(self new open: fullName forWrite: true) ifNil: ["File does not exist..." (FileDoesNotExistException fileName: fullName) signal] ? Feels abit silly to open a file to see if it exists, then close it, then open it again before returning it... (It also causes an unneccessary rehash of StandardFileStream registry on success) Cheers, Henry

[Pharo-project] About the changes files fixes
by StÃ©phane Ducasse July 2, 2009

July 2, 2009

Hi hernan I read your code and normally the notification alone should be enough. The changelog should be listening to the notification and log what should be logged. So in the following the first line should only be necessary self notifyOfChangedCategoryFrom: oldCat to: newCat. changeString := subject name, ' organization renameCategory: ''', oldCatString ,''' toBe: ''', newCatString ,''''. SmalltalkImage current logChange: changeString I imagine that may be there is problem because the ChangeLog does not listen to the right event or it is not listening well. Because the systemNotification worked (may be the changes you want were not taken into account) from when it was introduced. So could you check because I'm 100% sure that Changeset logger was treated by roel code just a any other client and he payed attention that if there is an exception we do not lose the code. Roel was picky on his code. Stef

If you open an inspector on a morph and try to edit the bounds, you get will the following error: OTNamedVariableNode(Object)>>doesNotUnderstand: #selectedClass Is this correct behaviour? [In Squeak by Example, we had an example where we did this.] - on
