Re: [Pharo-project] Pharo Association

by Marcus Denker

Thank you for your suggestions! I am making a list of what to improve and added them (the association pharo vs. pharo association one I think is not to fix sadly...)

Re: [Pharo-project] [NativeBoost] calls to munmap always fail on OS X 10.8.2

by Max Leske

It seems I found a fix. I simply copied the code from the "mmap" call over to "munmap". Can somebody (Igor?) *please* confirm that this is ok to do? My tests are green but I'm really not sure about thisâ¦ Here's the new code for NBMacExternalHeapManager>>unmap:length: NBMacExternalHeapManager >>unmap: addr length: len <primitive: #primitiveNativeCall module: #NativeBoostPlugin error: errorCode> "unmap memory page" ^ NBFFICallout cdecl: #( int (uint addr, ulong len) ) emitCall: [:gen | | munmap | munmap := NativeBoost forCurrentPlatform getGlobalSymbolPointer: 'munmap'. gen asm mov: munmap asUImm32 to: gen asm EAX. gen asm call: gen asm EAX ] options: #( - optDirectProxyFnAddress ) Cheers, Max On 16.11.2012, at 14:11, Max Leske <maxleske(a)gmail.com> wrote: > A followup on the munmap issue: > > I think it has something to do with how NativeBoost does the lookup.

Re: [Pharo-project] [NativeBoost] calls to munmap always fail on OS X 10.8.2

by Max Leske

A followup on the munmap issue: I think it has something to do with how NativeBoost does the lookup. I looked at the way that "mmap" is called and noticed that the selector #getGlobalSymbolPointer: is being used. Resolving "munmap" with this selector succeeds while doing NativeBoost loadSymbol: 'munmap' aName fromModule: -2 (which is what happens when the heap manager tries to call "munmap") results the stack trace shown below. I'll keep digging...

Re: [Pharo-project] Package-pane (or 6-paned) browser for Pharo?

by Goubier Thierry

Hi Travis, there is also an experimental tree-based system browser here : http://ss3.gemstone.com/ss/Alt-Browser.html It goes all the way towards removing all the panes, starting with regrouping packages in groups based on prefix or categories, all the way to system categories. It's usable on Pharo 2.0; I'm planning to tie it completely with RB so that everything you do with it appear as a RB undoable change Thierry Le 16/11/2012 13:45, StÃ©phane Ducasse a Ã©crit : > Hi Travis > > Welcome :) > > Have a look at Nautilus in Pharo20.

Re: [Pharo-project] Package-pane (or 6-paned) browser for Pharo?

Hi Travis Welcome :) Have a look at Nautilus in Pharo20. It supports groups, packages, categories, refactoringsâ¦. Multiple selection, multiple method browsing. Nautilus has a plugin architecture. Pavel wrote periscope to suport fast navigation. Since we changed a lot the package structure + announcements, currently packages are not displayed with trees but this was the plan. Ben was waiting that we stop changing everything and we are getting there. Esteban will probably rewrite using spec.

At the moment we would be completely and utterly lost without OSProcess. So yes, OSProcess is great. But then, for one, it's a VM plugin. There's also a lot of magic going on wich makes it kind of hard to debug sometimes. Talking of an "OSProcess replacement" was a bit harsh I reckon, what I actually ment was "OSProcess alternative", especially a light one (for now).
