SessionManager and SystemSettings?

by Nicolai Hess

My stored settings aren't loaded at start up anymore (for example, in Pharo 60107). any ideas?

Functional callbacks on all Cog platforms

by Eliot Miranda

Hi All, just wanted to report that as of Alien-eem.35 and https://github.com/OpenSmalltalk/vm/commit/da3fafdec9444754af104e0ed9f613f6… we now have functional callbacks on all x86 platforms, ARM32 platforms and x86_64 platforms. There's a simple example Alien class>>exampleCqsort that shows how to use the system and tests the implementation using the C library's sort quick sort implementation that takes a function pointer as an argument to use for comparing pairs of elements. This is mapped onto a Smalltalk block by Alien's callback implementation. The example sorts 100 random double-precision floats using qsort and a callback into Smalltalk. _,,,^..^,,,_ best, Eliot

It was an exception to the rule in VisualWorks and its convenience is so strong I brought it over. But the Squeak/Pharo code dates back to 2008 when I added this in Newspeak, which runs on Squeak. > It's a special temporary variable that holds an error code. The special object array defines a list of error code that the VM can use to explain to the programmer why the primitive failed, which are currently symbols. Right. In the VM primitive failure is indicated by a variable called primFailCode being non-zero. On activating a method with a failing primitive, if the index is in bounds of the primitiveFailCodes array in the specialObjectsArray then the failure code substitutes the symbol in the primitiveFailCodes array, otherwise it supplies the integer value. This is simpler than the VW scheme which allocates a PrimFailCode that has a name inst car and a parameter. Our system has only the name. > >> On Wed, Jun 22, 2016 at 4:22 PM, Max Leske <maxleske(a)gmail.com> wrote: >> >> > On 22 Jun 2016, at 15:59, stepharo <stepharo(a)free.fr> wrote: >> > >> > Hi >> > >> > I want to explain where ec is coming. >> > >> > I thought that the arguments of pragmas could only be literal and when I see ec it looks like a variable set by the VM >> > >> > >> > newMethod: numberOfBytes header: headerWord >> > "Primitive.

Re: [Pharo-dev] AthensCairoSurface not getting garbage collected

by J.F. Rick

Here's some more information on this: When I was having this issue, Pharo was pretty unstable. It would crash regularly when using AthensCairoSurface. It would also sometimes have weird visual artifacts. I'm not sure what these were but it almost looked like the bits were shifted so that rgb turned into gbr or something. Anyway, I've gone ahead and dumped that image, loaded all the same code, and started making sure that I don't save the image when testing the code. I haven't had a crash since. Perhaps that gives a clue about what was going on. Cheers, Jeff PS This is on the Ubuntu16 and Pharo5. On Sat, Jun 18, 2016 at 12:36 PM J.F.

Re: [Pharo-dev] <primitive: 79 error: ec> question

by ClÃ©ment Bera

It's a special case added a couple year ago to figure out why a primitive fail. It's a special temporary variable that holds an error code. The special object array defines a list of error code that the VM can use to explain to the programmer why the primitive failed, which are currently symbols.
