[Pharo-project] Pharo crashes with 64 bit VM on Ubuntu
by paul provoost Nov. 23, 2008

Nov. 23, 2008

Hi, I compiled and installed the latest 64bit Squeak VM for Linux using the source tarball of Ians Piumarta's website. Compilation was succesfull, and Damien Cassous Squeak dev image runs fine. Pharo however crashes after the first try to claim more memory. The output on the commandline is: squeak: /test/squeak/Squeak-3.10-4/platforms/unix/vm/sqUnixMemory.c:172: uxGrowMemoryBy: Assertion `newDelta >= 0' failed. This problem can easily be reproduced by starting up the base image Pharo0.1Core-10164.image and opening the system browser, or doing something that requires extra memory like 10000 factorial in a workspace. Damiens Pharo dev image behaves exactly in the same way. Starting Pharo with command line argument -memory 4096m only delays the problem: after a few mouseclicks Pharo crashes. Any suggestions?

[Pharo-project] Rio File/Directory
by Keith Hodges Nov. 23, 2008

Nov. 23, 2008

Just to let you guys know, A while back I did the work of moving Rio over to use classes File and Directory, and String>>asFile and String>>AsDirectory. I am tempted to leave it that way for now (i dont have time to do otherwise for a bit) since I do want to propose it as a standard thing that could be in Squeak/Pharo/Whatever. Code size stats: self compiledSize: 'File-Kernel'. 6906 (for Kernel Images) self compiledSize: 'File-Base'. 8215 (includes some ftp remote directory support) self compiledSize: 'Files-Directories'. 11471 self compiledSize: 'FileMan-Core'. 7098 self compiledSize: 'Network-RemoteDirectory'. 21481 regards Keith

[Pharo-project] Two points
by StÃ©phane Ducasse Nov. 22, 2008

Nov. 22, 2008

Hi all I would like to stress two points: - I would like to see the code we are harvesting more tested. - but I would like that in alpha phase we continue to move on. So this is clearly difficult. In french we say that we cannot do an omelet without breaking eggs. Still I would like to stress two points: - I would like to see the code we are harvesting more tested. - but I would like that in not alpha phase we continue to move on. You know what I mean and we are trying to do our best. Now it means that people should also react fast to their submission feedback, which is the case since now. But we should continue but keeping in mind the two points above are important. In the beta phase we will not go at that pace and really stabilize the system. Then also we should favor improvement at the package level: for example the SUnit changes should in the future be really considered from the perspective of a external package improvement process. So a group of people can work on building a better SUnit (integrating/merging... keith improvement for example) and that we can build pharo-dev. Stef

[Pharo-project] About nile
by StÃ©phane Ducasse Nov. 22, 2008

Nov. 22, 2008

Hi I would like to have Nile in the image because I want to get rid of the old stream implementations slowly migrating the missing parts slowly to nile and I'm afraid that we lose the great work on damienC. I tried to harvest yesterday the item related to the back broken behavior in stream hierarchy but too much changes already happened. I could not find my way and lost time. I asked damien to help me but this is a sign. The plan could be to have Nile in Pharo-Dev for a couple of milestone and at a point switch (remove the old stream hierarchy and replace it by Nile). Also with DamienP we wrote more tests on collections and traits are really working great for that. Really! I imagine that we will have a really good test basis for the collections soon and that with Nile in the image I can improve the test coverage of Streams. I should say that I really fed up with some of the code aspects of Squeak (fileout of classes for example is a huge mess, file/directory....). Stef

[Pharo-project] List of Type entry
by StÃ©phane Ducasse Nov. 22, 2008

Nov. 22, 2008

Hi guys I added two type entries Type-Defect = Report of a software defect Type-Enhancement = Request for enhancement Type-Task = Work item that doesn't change the code or docs Type-Patch = Source code patch for review Type-Mantis = Ticket on bugs.squeak.org to integrate Type-Squeak = Squeak version to integrate Type-Other = Some other kind of issue Type-ToDo = To list some todo for the coming versions Type-NextMilestone = To remember some actions for the next milestones I would like that we used them to sort well the items Stef

[Pharo-project] isTransparent
by StÃ©phane Ducasse Nov. 22, 2008

Nov. 22, 2008

If you want to have fun do Object new setHaltOnce redefine Object>>isTransparent self haltOnce. Beeper beep. ^ false I found a kind of fix by initializing correctly SimpleBorder (my fix is not totally convincing yet since it crashed the image). SimpleBorder is used in BorderedSubpaneDividerMorph Now what is amazing to me is the number of time isTransparent is invoked on Object when just typing text, I think that there is bogus there. If one UI expert can have a look this would be great. Stef

[Pharo-project] Issue 310/311
by Pavel Krivanek Nov. 21, 2008

Hi, I created a patch for issue 310/311 that categorizes all Pharo tests in own packages. So all tests in Pharo are then unloadable. http://code.google.com/p/pharo/issues/detail?id=310 -- Pavel

I have another question why are we forced to click on a method category to define one? We could click on the class and paste a method body then select a category... This is another illustration that the UI of Smalltalk browser is full of modes. I would really like to see an IDE where we limit the number of modes. For example it would be great to maximize the number of shortcut that are transparent = that are not linked to a pane. right now apple-F is linked to look for a class in the class category. but this would be great to have it working anywhere. apple-w to close a window only work on the pasteUpMorph I'm sure that there are a lot more of such case. I went over the shortcut list and lot of them are not working and it would be good to check and rethink them. Stef PS: David the inheritance pane is now working extremely well. It is really cool to be able to double click on it to see the new inheritance tree and the switch between the smart group selection and the package view is really great. Really this is getting really really smooth. I really have to pay attention to notice that it is working well. Also the fact that I can type an word and get the classes, methods in a smart group is great. I start to go really fast with your browser.
