InputEventFetcher update
by Christophe Demarey Nov. 16, 2015

Nov. 16, 2015

Hi, I'm working on the new startup/shutdown mechanism and I came to discover InputEventFetcher. What are the instruction to properly initialize / re-initialize the InputEventFetcher ? I tried InputEventFetcher deinstall; install and InputEventFetcher shutDown; deinstall; install; startUp but both end to an image not responding to mouse / keyboard events. Thanks for any help, Christophe

Debugging VM crash, INVALID RECEIVER / a(n) bad class ??
by Mariano Martinez Peck Nov. 16, 2015

Nov. 16, 2015

Hi guys, I am debugging a Pharo VM crash I am having and I cannot figure out what it is exactly. I suspect it might be related to block closures compilation but I am not sure. I have a reproducible crash test under Pharo 4.0 and OSX. I built a VM in debug mode and I run it via gdb. This is the kind of info I am able to see: *Program received signal SIGSEGV, Segmentation fault.* *0x000ab66b in updatePointersInRangeFromto (memStart=924623948, memEnd=928201420) at /Users/mariano/Pharo/git/pharo-vm/src/vm/gcc3x-cointerp.c:40444* *40444 && (((longAt(fieldOop)) & MarkBit) != 0)) {* *(gdb) call printAllStacks()* *Process 0x30e228c4 priority 40* *0xbffb2e10 M FaAction class>block: 0x20ebb104: a(n) FaAction class* *0xbffb2e30 M BlockClosure(FaMemoryStoreSession)>register: 0x371d0968: a(n) BlockClosure* *0xbffb2e4c M INVALID RECEIVER>register: 0x371cfd54: a(n) bad class* *(callerContextOrNil == (nilObject())) || (isContext(callerContextOrNil)) 48626* *0x3721e1f0 is not a context* *0x371c34b4 is not a context* And another crash: *Program received signal SIGSEGV, Segmentation fault.* *0x000ab66b in updatePointersInRangeFromto (memStart=924677864, memEnd=928262300) at /Users/mariano/Pharo/git/pharo-vm/src/vm/gcc3x-cointerp.c:40444* *40444 && (((longAt(fieldOop)) & MarkBit) != 0)) {* *(gdb) call printAllStacks()* *Process 0x30e228c4 priority 40* *0xbffb2de0 M INVALID RECEIVER>initialize 0x3722b9a0: a(n) bad class* *0xbffb2df8 M FaAction class(Behavior)>new 0x20ebb104: a(n) FaAction class* *0xbffb2e10 M FaAction class>block: 0x20ebb104: a(n) FaAction class* *0xbffb2e30 M INVALID RECEIVER>register: 0x371ddee0: a(n) bad class* *0xbffb2e4c M INVALID RECEIVER>register: 0x371dd328 is in old space* *(callerContextOrNil == (nilObject())) || (isContext(callerContextOrNil)) 48626* *0x3722b750 is not a context* *[New Thread 0x1b43 of process 5886]* *[New Thread 0x1d2f of process 5886]* *[New Thread 0x1f07 of process 5886]* *[New Thread 0x1e07 of process 5886]* >From what I can see in *#printActivationNameFor: aMethod receiver: anObject isBlock: isBlock firstTemporary: maybeMessage* It looks like if the memory address is not an OOP, nor forwarding pointer nor... It also seems like the above stack I can get is not the real cause but a side effect that makes GC to crash (#updatePointersInRangeFromto) As said, I have a way to reproduce the crash, and I already have the VM compiled in debug and gdb running. I can also attach the full output of the gdb stack. BTW.... in the output of the gdb I see lots of printings like: *(numStack + ReceiverIndex) < (lengthOf(theContext)) 45421* *(ReceiverIndex + contextSize) < (lengthOfbaseHeaderformat(oop, header2, fmt)) 40416* Any pointer is appreciated. Thanks! -- Mariano http://marianopeck.wordpress.com

[Reflectivity] Method level breakpoints are back
by marcus.denker＠inria.fr Nov. 16, 2015

Nov. 16, 2015

Hi, 50 441 now has simple method level breakpoints that are implemented using Reflectivity MetaLinks. Like the old breakpoints on Pharo3 and earlier, there is a menu entry to add (or remove) a break. The method icon is that of a #halt for now for active breakpoints. Next: Merge with the AST level breakpoint model. Marcus

keyboard events in the windows VM
by Nicolai Hess Nov. 16, 2015

Nov. 16, 2015

A short overview: With Ctrl-Key pressed, some keyboard events don't generate smalltalk keystrokes (EventKeyChar) ctrl+tab, ctrl+1, ctrl+2, ..., ctrl+0, ctrl+Tab, ctrl+m for some keyboard events there are only key down and key up events (from windows) but the vm "generates" a keypress (EventKeyChar) event ctrl+Home, ctrl+End, ctrl+PageUp, ... But the key value , char code and ctrl flag for this generated events, make them undistinguishable from other ctrl+key shortcuts ctrl+a = ctrl+Home, ctrl+d = ctrl+End, ctrl+k=ctrl+PageUp,... And one key (ctrl+Enter) creates two EventKeyChar events one "normal" and one that is generated from the vm one with keyvalue 10 and one with 13. And the keycode for char like "a","b", ..., are different if you they are typed with or without ctrl-key just key "a": keycode: 65 (keydown event) 97 (keyvalue/charcode event) (65 if you press shift key) 65 (keyup event) with ctrl key pressed: keycode 65 (keydown event) 1 (keyvalue/charcode event) 65 (keyup event) I would like to change this, that means: generate EventKeyChar events for ctrl+1, ctrl+2, ..., ctrl+Tab, ctrl+m remove the double key event for ctrl+Enter and adopt the behavior of the linux vm, for keyValue, charCode values for events like ctrl+a, ctrl+home, ... for example, the linux vm generates event buffer values: #(2 7329656 1 0 2 65 0 1) for ctrl+a (keyValue 1/charCode 65) but #(2 7329656 1 0 2 1 0 1) for ctrl+home (keyValue 1/charCode 1) this may need some changes on the image side. For example, in Pharo we have some special handling that adds "96" to the keyValue for keystrokes with ctrl-key). What do you think? nicolai
