[Pharo-project] About Nautilus "show class"
by Igor Stasenko Jan. 19, 2013

Jan. 19, 2013

Hi, first, i must say, using a checkbox to switch between instance/class side is good idea, much much less confusing than with 2-state button. i just don't happy with label, imo a better label would be 'class side' -- Best regards, Igor Stasenko.

[Pharo-project] Do you plan for Pharo2.0 migrate main repositories to SmalltalkHub?
by Denis Kudriashov Jan. 19, 2013

Hello Squeaksource seems down. I notice this when try open configuration browser. It hanges on squeaksource metacello repository reading. And squeaksource is deprecated resource. So do you plan for Pharo 2.0 to migrate main repositories to SmalltalkHub? Best regards, Denis

[Pharo-project] Class initialisation after loading
by Sven Van Caekenberghe Jan. 19, 2013

Jan. 19, 2013

Hi, For a long time I have been having troubles with #initialize (not) being sent to classes that just got loaded. Apparently #initialize is only sent to *newly* loaded classes that did not exist before ? It does not get sent to existing classes being reloaded/overwritten ? Does the fact that the #initialize class method itself gets overwritten (actually changes) have anything to do with it ? What would be the best practice here ? The most portable one ? I want to be able to make sure #initialize is sent when I want it. Thx, Sven PS: I am looking for a solution that would work for Monticello package loading, via Gofer or Metacello as well as regular #fileIn. -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

[Pharo-project] Manifest...
by Camillo Bruni Jan. 19, 2013

Jan. 19, 2013

Why do the Manifest.* classes have no class comments? This is highly confusing, as these things are created without any notification, so at least they should have an auto-generated comment which states what they are good for. cami

[Pharo-project] Why I love SmallLint
by StÃ©phane Ducasse Jan. 18, 2013

Jan. 18, 2013

Hi guys We will start to have a huge fun :) We are starting to apply systematically apply SmallLint rules to all Pharo2.0 version and it is unbelievable what we will improve. We brainstormed today with Marcus, Simon and Andre. And I could not resist to run and fix on rule :). Since we believe that simple practices and dummy ideas can have an impact, I started to run the "Method just send super message" and fix the problems that are not in test classes. This is so cool. I could even fix such glitch in Zinc :) So I'm really happy. I will apply rules one by one and fix as much as I can :). Then in the future, we will apply the result of andre's PhD to create rules based on our development history. So we will have quite cool rules to cover Pharo and also help you to migrate your code from one version to the other. http://code.google.com/p/pharo/issues/detail?id=7288 Stef

[Pharo-project] new Cog VMs available
by Eliot Miranda Jan. 18, 2013

Jan. 18, 2013

at http://www.mirandabanda.org/files/Cog/VM/VM.r2673. Fix becomeForward: when the rootTbale overflows. There were two bugs here. One is that initializeMemoryFirstFree: used to clear the needGCFlag so if the rootTable overflowed noteAsRoot:headerLoc:'s setting of the needGCFlag would be undone after the sweep. The other is that rooitTable overflow was indicated by rootTableCount >= RootTableSize which could be undone by becomeForward: freeing roots which need to be removed from the rootTable. At some point in becomeForward the rootTable would fill but at a later point a root would be freed, causing the table to become not full. The fix is two fold. 1. Add an explicit rootTableOverflowed flag instead of relying on rootTableCount >= RootTableSize. 2. move the clearing of the needGCFlag to the GC routines. Remove unnecessary senders of needGCFlag: false, and remove the accessor. As a side effect rewrite primitiveRootTable in terms of a new ObjectMemory>>rootTableObject. Remove the rootTable: accessor. Implement checkAllAccessibleObjectsOkay & checkOkayInterpreterObjects: (used to debug the above). Fix NewObjectMemory initialization to set freeStart at the same time as setting endOfMemory. This allows load-time scans and assert code to use freeStart instead of endOfMemory. Simplify markAndTraceStackPage: ; since the two implementations are distinct they don't need to contain the isCog if-then-else. Implement NewObjectMemory>>shorten:toIndexableSize: so that the last object is correctly shortened (cut back freeStart). Refactor the allocation check filling code into maybeFillWithAllocationCheckFillerFrom:to:. Make longPrintOop: print the class oop. Fix bug in printCallStackOf:currentFP: for widowed contexts. Use fputs for print: instead of printf. Rewrite the stackLimit computation after a moment of clarity. Allow the system to reduce the space for frames by up to an 1/8th. Make sure there's at least as much headroom as asked for. This changes the stack page size from 4096 to 2048 and much reduces the interpreterAllocationReserveBytes. Don't round up interpreterAllocationReserveBytes to a power of two. Integrate the named serial primitives plus Luc Fabresse's latest fix. Improve cygwin HoiwToBuilds with info on latest versions (thanks Ron). -- best, Eliot
