[Pharo-project] macintosh carbon VM goes to legacy status.
by John M McIntosh Nov. 14, 2009

Nov. 14, 2009

The macintosh carbon VM is going into a legacy support state. Why? ESUG has provided me with some funds to help build a new 32/64 bit Cocoa (intel/ppc) based Squeak VM, please don't forget to thank them for supporting the community. Today based on the iPhone VM tree and many more hours of effort I managed to start up a 64 bit intel based Cocoa VM using a 32bit squeak image. I still have a "bit" more to go in order to get the keyboard logic to correctly mimic the older carbon behaviour, so I won't start public beta testing until the end of the month. And it only feels like a sea of "warning: cast from pointer to integer of different size" to work thru, but previous efforts by folks like David T Lewis has reduced that to I think a manageable issue. If you are interested in alpha testing the VM please email me privately and I'll see if I can get you a workable VM by the end of next week. The primary project goal is to: Build a new cocoa based 32/64bit intel/ppc VM with an MIT license, basically from scratch, to enable the ability to use a 32bit image or 64bit image. Some other objectives: To build it from scratch using the 4.2.2 VM as a reference To ensure the xcode project can build both an OSX VM and a iPhone VM. Port as little code from the past, excluding the Socket and basic file I/O logic. Other plugins address as needed. -- =========================================================================== John M.

[Pharo-project] x4 difference between #to:do: and #timesRepeat - bug ?
by CÃ©drick BÃ©ler Nov. 13, 2009

Nov. 13, 2009

Hi, I noticed quite a difference between the two method who "looks" the same to me. Is it normal ? I use a rc image (haven't tested in squeak). And it's the same on windows and linux. count := 0. [1 to: 10000000 do: [:i | count :=count + 1]] timeToRun." 677" count := 0. [10000000 timesRepeat: [count := count + 1]] timeToRun" 2571" If not normal, I'll open a issue. Thanks -- CÃ©drick

[Pharo-project] Issue 1437 : Bitmap #decompress:fromByteArray:at: not wellformed
by arnaud Jean Baptiste Nov. 13, 2009

Nov. 13, 2009

I paste the issue open : the primitive method #decompress:fromByteArray:at: aren't well-formed, cause the code of this method is using by VMMaker to generate source code of the primitive, then it can happen which a selector using in the method was never implemented. Then if the code is fix VMMaker may not be able to generate a clean source code. the main point of this issue is the selector call: #primitiveFail, he doesn't exist in the Pharo environment and seem be change by #primitiveFailed which exist, and then the mistake can't be see if we don't try to generate to use VMMaker without using MiscPrimitivesPlugin. I post a fix in the Inbox. i have simply correct #primitiveFailed to #primitiveFail If you have a better solution i will be glad to discuss with you. link : http://code.google.com/p/pharo/issues/detail?id=1437

[Pharo-project] testing morphs
by Tudor Girba Nov. 13, 2009

Nov. 13, 2009

Hi, I would like to test the code related to rendering a morphic interface. In particular, I would like to test the rendering of Glamour browsers with morphic. The problem is that the rendering happens in another process than my regular test code. Any idea of how I could solve this problem? Cheers, Doru -- www.tudorgirba.com "Don't give to get. Just give."
