Re: [Pharo-project] Experimental Cocoa OS-X based Squeak Cog JIT VM 5.8b10

by Esteban Lorenzano

Hi, I can't run Pharo Dev 1.1 with cogvm (5.8b10 or the binaries compiled by Eliot). This is what I'm doing: 1) download Pharo Dev 1.1 2) with older VM (4.2.2) I start Pharo, and file in "NecessaryImageChangesForCogToWork.Pharo1.1.cs" 3) save and quit 4) try to open with cogvm (any cog vm) the image hangs with this info: Process: Squeak [66151] Path: /Users/MAC/Desktop/Dev/ESUG/Squeak 5.8b10.app/Contents/MacOS/Squeak Identifier: org.squeak.Squeak Version: 5.8b10 (28.0) Code Type: X86 (Native) Parent Process: launchd [101] Date/Time: 2010-09-10 12:00:27.323 +0200 OS Version: Mac OS X 10.6.4 (10F569) Report Version: 6 Interval Since Last Report: 180097 sec Crashes Since Last Report: 4 Per-App Crashes Since Last Report: 3 Anonymous UUID: 6CBAB42F-B15F-4B9C-B344-2663CE41C421 Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000008 Crashed Thread: 0 Dispatch queue: com.apple.main-thread Thread 0 Crashed: Dispatch queue: com.apple.main-thread 0 org.squeak.Squeak 0x000a435b ceSendsupertonumArgs + 379 Thread 1: 0 libSystem.B.dylib 0x921da9d2 __workq_kernreturn + 10 1 libSystem.B.dylib 0x921daf68 _pthread_wqthread + 941 2 libSystem.B.dylib 0x921dab86 start_wqthread + 30 Thread 2: Dispatch queue: com.apple.libdispatch-manager 0 libSystem.B.dylib 0x921db942 kevent + 10 1 libSystem.B.dylib 0x921dc05c _dispatch_mgr_invoke + 215 2 libSystem.B.dylib 0x921db519 _dispatch_queue_invoke + 163 3 libSystem.B.dylib 0x921db2be _dispatch_worker_thread2 + 240 4 libSystem.B.dylib 0x921dad41 _pthread_wqthread + 390 5 libSystem.B.dylib 0x921dab86 start_wqthread + 30 Thread 3: 0 libSystem.B.dylib 0x921b50fa mach_msg_trap + 10 1 libSystem.B.dylib 0x921b5867 mach_msg + 68 2 com.apple.CoreFoundation 0x95bd9faf __CFRunLoopRun + 2079 3 com.apple.CoreFoundation 0x95bd9094 CFRunLoopRunSpecific + 452 4 com.apple.CoreFoundation 0x95bd8ec1 CFRunLoopRunInMode + 97 5 ....audio.toolbox.AudioToolbox 0x98e48cda GenericRunLoopThread::RunLoop() + 60 6 ....audio.toolbox.AudioToolbox 0x98e49096 GenericRunLoopThread::Run() + 158 7 ....audio.toolbox.AudioToolbox 0x98e0c128 CAPThread::Entry(CAPThread*) + 96 8 libSystem.B.dylib 0x921e281d _pthread_start + 345 9 libSystem.B.dylib 0x921e26a2 thread_start + 34 Thread 4: 0 libSystem.B.dylib 0x921b515a semaphore_timedwait_signal_trap + 10 1 libSystem.B.dylib 0x921e2ca5 _pthread_cond_wait + 1066 2 libSystem.B.dylib 0x92211848 pthread_cond_timedwait_relative_np + 47 3 com.apple.audio.CoreAudio 0x978e1805 CAGuard::WaitFor(unsigned long long) + 219 4 com.apple.audio.CoreAudio 0x978e4837 CAGuard::WaitUntil(unsigned long long) + 289 5 com.apple.audio.CoreAudio 0x978e2134 HP_IOThread::WorkLoop() + 1892 6 com.apple.audio.CoreAudio 0x978e19cb HP_IOThread::ThreadEntry(HP_IOThread*) + 17 7 com.apple.audio.CoreAudio 0x978e18e2 CAPThread::Entry(CAPThread*) + 140 8 libSystem.B.dylib 0x921e281d _pthread_start + 345 9 libSystem.B.dylib 0x921e26a2 thread_start + 34 Thread 5: 0 libSystem.B.dylib 0x921e3066 __semwait_signal + 10 1 libSystem.B.dylib 0x9220ec64 nanosleep$UNIX2003 + 188 2 org.squeak.Squeak 0x000abc39 beatStateMachine + 153 3 libSystem.B.dylib 0x921e26a2 thread_start + 34 Thread 0 crashed with X86 Thread State (32-bit): eax: 0x00000000 ebx: 0x00000000 ecx: 0x00000c14 edx: 0x1f557054 edi: 0x00000000 esi: 0x1f500004 ebp: 0x00000001 esp: 0xbff5cd90 ss: 0x0000001f efl: 0x00010297 eip: 0x000a435b cs: 0x00000017 ds: 0x0000001f es: 0x0000001f fs: 0x00000000 gs: 0x00000037 cr2: 0x00000008 Binary Images: 0x1000 - 0xbeff7 +org.squeak.Squeak 5.8b10 (28.0) <4B128097-8BD6-1888-F089-6AD2AFE0E890> /Users/MAC/Desktop/Dev/ESUG/Squeak 5.8b10.app/Contents/MacOS/Squeak 0x1c2000 - 0x1e5fe7 GLRendererFloat ???

Re: [Pharo-project] Pharo-project Digest, Vol 29, Issue 57

by Michael Roberts

Hi, i don't know why things are done the way they are... Is your question how the exception mechanism works, or why it is needed to be done with an exception? as opposed to say doing it some other way? The direct answer to your question is that given it is implemented in terms of exceptions, the signal is needed to trigger the defaultAction, or to allow someone higher up in the stack to trap it and redirect the notification. hth cheers, Mike On Fri, Sep 10, 2010 at 4:37 AM, Ralph Boland <rpboland(a)gmail.com> wrote: > I posted the following earlier to the Squeak list but didn't get a responce. > Hopefully someone on the Pharo list can help me.

I posted the following earlier to the Squeak list but didn't get a responce. Hopefully someone on the Pharo list can help me. I need this information so I can make some planned changes to the ProgressDisplay package I released a while back. ----------------------------------------------------------------------------------------------------------------- A SystemProgressMorph is used to display progress while some computation is being done. Furthermore the progress bars can be stacked to show progress of component computations within a computation. This I understand and understand most of the code. But not All. What I have trouble with is understanding why a ProgressInitiationException is needed. In particular, String>>displayProgressAt:from:to:during: does: ProgressInitiationException display: self at: aPoint from: minVal to: maxVal during: workBlock. This method sets a few variables and then does: ^self signal This signal is caught where upon a SystemProgressMorph is started or extended with an additional progress bar. But I don't understand why sending a signal to a ProgressInitiationException is needed to get the ball rolling, Can someone please explain why things are done the way they are? Regards, Ralph Boland

Re: [Pharo-project] Feature Request: Strict Compiler / Monticello Mode

by Tudor Girba

Indeed, we moved Moose from Pharo 1.0 to Pharo 1.1 in a couple of hours, and everything worked out perfectly. The coolest thing was that simply moving from one Pharo to the other basically improved the product performance with about 40% :). So, even from the point of view of a large project, change is not a problem. In fact, it is wanted. Addressing the question of how one should upgrade the code without changing the image ... I will say that at this point I do not want that. I want to be able to load my code in a new image at any time. So, from my point of view, I will upgrade my image by simply loading the code in the new image.
