[Pharo-project] Cannot abandon sources with CogVM

by Mariano Martinez Peck

Hi. If I take any PharoCore 1.3 image and evaluate: Smalltalk abandonSources I have two errors and the image is frozen. I cannot interrupt it and I have to force a quite. Two erros pops up: the first one says "computation has been terminated" and the second one is a stacktrace which message: "UndefinedObject(Object)>>doesNotUnderstand: #findNextHandlerContextStarting" This seems similar to the problem we have with the DebuggerMethodMap trying to build a dev image: http://code.google.com/p/pharo/issues/detail?id=4087 At least this time it is easier to reproduce ;) I attach PharoDebug.log. With the Interpreter VM it works correctly. Thanks -- Mariano http://marianopeck.wordpress.com

Re: [Pharo-project] If sources file is not present, something bad happens

by StÃ©phane Ducasse

We will check that. I know that we should condense the changes to see if we can make it. I know that there was a problem the last time I tried. stef On May 8, 2011, at 9:50 PM, Mariano Martinez Peck wrote: > Hi guys.

[Pharo-project] If sources file is not present, something bad happens

by Mariano Martinez Peck

Hi guys. In pharo 1.1, 1.2 (in fact, always) one could decide not to use the .sources file and instead decompile. At startup the image raises a popup saying "ehhhh the .sources couludnt be found" and then after, when you browse a method you see the decompiled code. Now, in Pharo 1.3 I REMOVE all possible .sources and the image doesn't say anything at startup. No popup. If I print SourceFiles I get -> an ExpandedSourceFileArray(nil MultiByteFileStream: '/Users/mariano/Pharo/imagenes/PharoCore-1.2/PharoCore-1.2.changes') So...the sources is not there. Two problems: 1) the first one is that the popup doesn't raise. 2) I cannot browse methods because a popup raises saying there was a probelm with the sources file: "There may be a problem with your sources file!". I attach screenshot. So...what could be happening? I will try to debug it... If someone can confirm please I open an ticket. -- Mariano http://marianopeck.wordpress.com

Yes it will because this is a pain. Probably we should solve it also in MC. May be this is fixed in Squeak. Did you check? I should go over the MC change made by chris but I should find time to do it.

Stef, off-topic question.... When I rename a package from the SystemBrowser, the extension methods' categories are not updated. This is a known problem. I don't know where the rename happens if it is UI or model....but in case it is the model (PackageInfo or RPackage) I would love to have that fixed in RPackage. cheers Mariano On Sun, May 8, 2011 at 5:48 PM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr>wrote: > Hi guys > > did one of you wrote a small Package checker that would check: > - that all the methods get a non nil category > - methods belong to a package loaded? > > I experienced a lot of problem with RPackage when loading broken code and > I would like to produce a little tool to validate packages so that we can > identify > problems and understand how to solve that in RPackage. > > Stef > -- Mariano http://marianopeck.wordpress.com

Ideas that was in my system and I like: - For a package, build a summary / overview using first sentence of each commented class comment. - Use yUML for generating inheritance diagram - Caching so it's not slow I still have an old image running here http://magaloma.seasidehosting.st/Collections-Arrayed You can download it here http://lolgzs.free.fr/pharo/simplewebdoc.zip but it's crappy code Laurent. > Then Camillo did it again...and call it WebDoc. > > But...still, from the user point of view, there is nothing.

[Pharo-project] Package validation?

by StÃ©phane Ducasse

Hi guys did one of you wrote a small Package checker that would check: - that all the methods get a non nil category - methods belong to a package loaded? I experienced a lot of problem with RPackage when loading broken code and I would like to produce a little tool to validate packages so that we can identify problems and understand how to solve that in RPackage.

From you now, from Alexandre Bergel, from Henrik Johansen, etc. But no one (or maybe I didn't see it) give a list of the real existent MessageTally limitations or problems. So far, the only thing I read is what Eliot says here: "show primitives quite accurately" So...which are the rest and what is solved by the SystemProfiler from OpenQwaq ??
