primitiveFailForOSError: causes assertion failure in the simulator
by Alistair Grant 25 Oct '18

25 Oct '18

Hi Eliot, Calling #primitiveFailForOSError: fails in the simulator (I guess I'm the first person to use it :-)). It works properly in a real VM, of course. I've included a stack dump below, but my guess is that PrimitiveError isn't a known class, so isn't guaranteed to be in classTableFirstPage, causing the assertion failure below. Am I on the right track here? Thanks, Alistair 22 October 2018 10:38:54.659355 pm VM: unix - Smalltalk Image: Squeak5.3alpha [latest update: #18235] - but with VMMaker.oscog-eem.2467 SecurityManager state: Restricted: false

Pull request: changes for Mac build system
by Tim Johnson 24 Oct '18

24 Oct '18

Hi, I've made a branch with the following commit message: Use output of xcode-select to determine path of Xcode in Mac Makefile, instead of hard-coding. xcode-select allows for multiple versions of Xcode to be installed and to be selected by the user. DO NOT put a space in a renamed Xcode.app, however: this will break SDK detection in the Makefile. Add OS X 10.14 SDKs for x64 build, as supplied by Xcode 10. which does the following: build.macos32x86/common/Makefile.flags & build.macos64x64/common/Makefile.flags: -XCODE:=/Applications/Xcode.app/Contents/Developer +XCODE:=$(shell /usr/bin/xcode-select -p) and: build.macos64x64/common/Makefile.flags -SDKs:=MacOSX10.10.sdk MacOSX10.11.sdk MacOSX10.12.sdk MacOSX10.13.sdk +SDKs:=MacOSX10.10.sdk MacOSX10.11.sdk MacOSX10.12.sdk MacOSX10.13.sdk MacOSX10.14.sdk However, I'm not sure I have permissions to push my branch and create a pull request. If that's the model you use, please let me know. I am use @tcj on github. Thanks, Tim

[OpenSmalltalk/opensmalltalk-vm] Added comments and removed PharoVM guards for windowing support (#296)
by Guille Polito 23 Oct '18

23 Oct '18

Last integration went too fast :) This PR does some cleanups: - remove the PharoVM guards, - added comments Answering the questions from the other thread: this should have no effect on systems using a single window. However, with multiple windowing systems, this makes the consumption of events a cooperative task. If let's say SDL does not consume its events (because we don't call the event processing routine), then those events stay in the queue. To make it more robust I've been trying to use a separate queue to store alien events and repost them in the queue afterwads, but I could not manage to make it work. And Cocoa's support/documentation does not help here...
