[Pharo-project] SandstoneDb + GOODS backend in Pharo 1.2
by Nicolas Petton April 15, 2011

April 15, 2011

Hi, I updated the GOODS backend for SandstoneDb to work with Pharo 1.2, and I fixed a few bugs related concurrent access. To download and test it: Gofer it squeaksource: 'SandstoneDb'; package: 'SandstoneDb'; load. Gofer it squeaksource: 'BTree'; package: 'Collections-BTree'; load. Gofer it squeaksource: 'GOODS'; package: 'GOODS'; package: 'GOODSPlatformSqueak'; load. Gofer it squeaksource: 'SDGoodsStore'; package: 'SandstoneGOODS'; load Start GOODS on localhost:6000, and restart your image. I also wrote a blog post about it (the first part of the post) http://nicolas-petton.fr/2011/04/15/load-balancing-iliad-applications.html Cheers, Nico -- Nicolas Petton http://www.nicolas-petton.fr

[Pharo-project] Issue 4015 in pharo: Fix in SmalltalkEditor
by pharo＠googlecode.com April 15, 2011

Status: FixProposed Owner: Benjamin...(a)gmail.com Labels: Nautilus New issue 4015 by Benjamin...(a)gmail.com: Fix in SmalltalkEditor http://code.google.com/p/pharo/issues/detail?id=4015 Related to: Issue 3908: Fix for pool variables references I have introduced a new method to retrieve the model selectedClass. Because the method name is different in Browser and in Nautilus/Finder/RML... I've also introduced a ugly dispatch ... I think this method name shouldn't be hardcoded, but I haven't any clue how to do it other than provided it to the SmalltalkEditor which sucks ...

[Pharo-project] Improving Pharo's Exception Hierarchy
by Sven Van Caekenberghe April 14, 2011

April 14, 2011

Hi All, I have this idea that I would like to discuss on the next Pharo sprint and maybe start to implement if there is some consensus on it. It has been mentioned many times before on this list that Object>>#error: should be replaced by signalling specific Exceptions in as many cases as possible (or where it makes sense). Even today, there was http://code.google.com/p/pharo/issues/detail?id=3987 ! I think the core system should set the example here, by defining a number of general purpose exceptions and by using them. Going over #error: senders will be a lot of work but can be done in incremental/Pharo steps. So I went over the current hierarchy, scanned quickly through their references and some #error: senders by fundamental classes and looked at some other Smalltalks. I came up with the following very rough draft of an extended hierarchy (** marks new exceptions). In between brackets are the instance variables. Of course, we have to discuss about naming, instance variables and opportunities for reuse and inheritance (could be fun). I am no expert on exceptions and would certainly like to learn more. I am probably overlooking some aspects. We have to keep this Smalltalk like, flexible, dynamic, not start mimicing other languages. Any step in this direction will be an improvement over the current situation. Really using them correctly throughout the system will take some time. Defining the hierarchy could be done rather quickly. Refactoring is always possible later on. Exception (messageText) Abort Error ArithemticError ZeroDivide (dividend) FloatingPointException RangeError ** (from, to) NaNError ** FileStreamException (fileName) FileDoesNotExistException (readOnly) FileExistsException (fileClass) CannotDeleteFileException FileWriteError FileReadError ** FileClosedException ** CannotAccessFileException ** ReadonlyFileException ** MessageNotUnderstood (message, receiver) NonBooleanReceiver (object) OutOfMemory Halt AssertionFailure BreakPoint SyntaxError ** !exists! (input, position) NumberFormatException ** HeadlessError ** TimedOut ** (object, operation, timeout) VerificationException IllegalOperation ** (operation, object) SizeMismatch (objects) LowMemory ** (percentageFree) SubclassResponsibility ** (message, receiver) NotYetImplemented ** (message, receiver) CannotInstanciate ** (class) ReadOnlyObject ** (object) OutOfFreeSpace ** (object, size) InvalidArgument ** (message, receiver, argument) NotIndexable ** (object) NoKeyedAccess ** (object) NonIntegerIndex ** (receiver, index) SubscriptOutOfBounds ** (receiver, index, from, to) NotFoundException ** (receiver, object) KeyNotFound ** ValueNotFound ** ElementNotFound ** StreamException (stream) PositionError ** (index, from, to) EndOfStream ** BeginOfStream ** All feedback is welcome. Regards, Sven
