Ok, well not sure what is going on
ioProcessEvents-> sqInt ioProcessEvents(void) { aioPoll(0); if(ioProcessEventsHandler) ioProcessEventsHandler(); //84 return 0; } where ioProcessEventsHandler is this void nativeIoProcessEvents(void) { //API Documented
if ([[NSThread currentThread] isCancelled]) { gQuitNowRightNow = YES; ioExit(); //This might not return, might call exittoshell } if ([getMainWindowDelegate() forceUpdateFlush]) { [getMainWindowDelegate() ioForceDisplayUpdate]; } if (interpreterProxy->methodPrimitiveIndex() == 0) { [gDelegateApp.squeakApplication pumpRunLoopEventSendAndSignal:YES]; } else { [gDelegateApp.squeakApplication pumpRunLoop]; }
if (gQuitNowRightNow) { ioExit(); //This might not return, might call exittoshell }
} But then we end up over in /* The stackPointer is below the stackLimit. This is either because of a stack overflow or the setting of stackLimit to indicate a possible interrupt. Check for interrupts and stackOverflow and deal with each appropriately. Answer if a context switch occurred. */
/* StackInterpreter>>#handleStackOverflowOrEventAllowContextSwitch: */ & /* If contextSwitchIfNotNil is nil we can't context switch. contextSwitchIfNotNil is set to nil by - the special primitiveClosureValueNoContextSwitch entry-point in block dispatch - the stack check in methods with primitive 198. In a normal method contextSwitchIfNotNil will be the method (see e.g. SimpleStackBasedCogit>>compileFrameBuild). In a block it will be the closure (see e.g. SimpleStackBasedCogit>>compileMethodBody). */ /* CoInterpreter>>#ceStackOverflow: */ On Thu, May 19, 2016 at 4:39 PM, Eliot Miranda <[hidden email]> wrote:
