Profiling and delay accuracy
by Andreas Raab 06 Aug '11

06 Aug '11

Hi Folks - For a long time now I had this feeling that MessageTally reports pretty bogus results in many situations without being able to precisely track down why this would be the case. Today I was looking at primitiveResponse() and, much to my surprise, noticed that the checkForInterrupts() that used to be there for years is gone (see Squeak3.6 for example which still has it). The sole reason for this check was to get both high delay accuracy and good profiling behavior. Consider this example: fc := FormCanvas on: Display. MessageTally spyOn:[ 1 to: 100 do:[:i| fc fillColor: Color white. fc printString. ]. ]. Using 3.6 this will be measured correctly as: **Tree** 87.5% {243ms} FormCanvas>>fillColor: |87.5% {243ms} GrafPort>>fillRect:offset: | 87.5% {243ms} GrafPort>>copyBits 12.5% {35ms} FormCanvas(Object)>>printString 12.5% {35ms} FormCanvas(Object)>>printStringLimitedTo: whereas the 3.10 reports it as **Tree** 99.6% {670ms} FormCanvas(Object)>>printString 94.9% {639ms} primitives 4.6% {31ms} FormCanvas(Object)>>printStringLimitedTo: I think you can see the problem and just imagine what this does to any cumulative results. I also wonder what that change does to platforms that don't have high-resolution asynchronous timers. This used to be the one place where we would catch timer changes at high resolution and unless the platform forces high resolution timer interrupts asynchronously (by resetting the interrupt counter) we must be loosing a lot in terms of delay accuracy. (it just so happens that the Windows VM *does* do asynchronous timer interrupts so I never noticed this but I'm very curious about the difference on Linux which typically still has pretty bad timer granularity). Any opinions? My feeling is that the timer check should go back in for all of the above reasons. At the very least a quickCheckForInterrupt() is required but I actually think putting the full check back in is worth it. Cheers, - Andreas

Joys of Squeak-dev image, VM Compiling on MacIntel and Spoon remote OtherBrowsing
by Ken G. Brown 16 Nov '10

16 Nov '10

MacPro OS X 10.4.9 Xcode 2.4.1 Squeak-dev-114-2, VMMaker 2.8b6.1, Squeak 3.8.15beta6U.app, and version 1657 of svn MacOS VM sources, and Spoon v2a12. Downloaded http://www.squeakvm.org/cgi-bin/viewcvs.cgi/ trunk version 1657 for MacOS Ran squeak-dev-beta-114-2.image on Squeak 3.8.15beta6U.app Loaded VMMaker 3.8b6.1 from dev image Universes. Generated vm sources by following instructions in <http://www.squeakvm.org/cgi-bin/viewcvs.cgi/trunk/platforms/Mac%20OS/vm/Doc…> Fought with Xcode wanting to use MacOSX10.3.9.sdk for ppc which was giving an error which was known and documented in the Readme. Finally figured out what Xcode wanted so built universal app just using 10.4.9 sdk. Couple issues: Exupery references remain in sqnamedPrims.h and sqPlatformSpecific.h from svn version 1657, I just commented them out. Notes said: Info-NPSqueak__Upgraded_.plist was to be found in the Developer directory. I could not find it so scammed a info.plist out of John's Squeak 3.8.15beta6U.app vm. Not sure what impact this has. And much, much diddling about figuring out various things... Finally got a build. It's a lot smaller (3.9MB) than John McIntosh's Squeak 3.8.15beta6U.app (8.1MB), and it looks like it is a PowerPC one but at least it runs. I'll look into the Xcode build process some more. Then: Replaced interp.c with Craig's interp.c for Spoon, rebuilt and got a VM with Spoon client stuff. Downloaded Spoon release 2a12. Moved a copy of Flow plugin from within Craig's naiad.app package into a plugins subdirectory where the new spoon client compatible MacIntel universal VM was run from. Followed Craig's Spoon instructions for loading niaid.st and niaid.pr into the 3.10 image (Squeak-dev-114-2) running on the new VM. Did the run spoon.app thing from Spoon.dmg (version 2a12), needs to be done twice if Safari is not running. Got Spoon processor running. Followed instructions again in the Spoon client and lo! Got OtherBrowser browsing the Spoon memory running on processor. Yay Craig! Who do i get to sign my certificate? :) Ken

3.11.3.2135 for Unix
by Ian Piumarta 05 Jan '10

05 Jan '10

Dear Unix Squeakers, 3.11.3.2135 for Unix is now available at squeakvm.org/unix (sources plus binaries for MacOS/Darwin, Linux, NetBSD, FreeBSD and Solaris, on Intel and, occasionally, PowerPC hardware). Some important stuff has changed in this release (see notes below) so please consider it a BETA release even though there is no beta tag on the version number. As usual: comments, suggestions, bug fixes (as whole files please *not* diffs) and any unwanted vinyl LPs sitting in your attic can be sent directly to me. Thanks. Enjoy! Ian Changes since 3.10-6: Numbering scheme changed to X.Y.Z.R where X.Y.Z = VMMaker version used to generate the Interpreter and R is the subversion revision of the platform support code. VMMaker and plugins updated to most recent versions; generated source regenerated: Balloon3D-Plugins-ar.4.mcz DBus-Plugin-bf.32.mcz GStreamer-Plugins-JMM.16.mcz Kedama-Plugins-yo.1.mcz Rome-Plugin-yo.39.mcz OSProcessPlugin-dtl.16.mcz VMConstruction-Plugins-AioPlugin-dtl.9.mcz VMConstruction-Plugins-XDisplayControlPlugin-dtl.7.mcz VMMaker-dtl.138.mcz Build system rewritten using CMake instead of autotools. Big THANK-YOU to Bert, Subbu and Dave Lewis for providing invaluable feedback. Any plugin can now be turned off in configure with the option '--without-<pluginName>'. Experimental PulseAudio driver (vm-sound-pulse) added, thanks to Derek O'Connell. Default is still OSS on Linux; if you want pulse you have to ask for it in one of the usual ways. FFI tweaked on Linux to avoid a potential FPU stack overflow. ClipboardExtendedPlugin will no longer try to build if you don't have X11 development headers and libs. FileCopyPlugin made resilient to EINTR. VM renamed to 'squeakvm'. 'squeak' is now a script that looks for 'squeakvm', figures out if you need any obscure command-line options, and then launches 'squeakvm' for you. This in turn allows... Plugin search stretegy rationalised and simplified. Default location is now the executable directory (where 'squeakvm' is installed). The -plugins argument can be a colon-separated list of locations to search, just like PATH. Plugins are named 'so.plugin' to make interference with FFI libraries less likely. NOTE: FFI libraries are no longer searched for in every single nook and cranny, which means you might have to set LD_LIBRARY_PATH (or your local equivalent) for FFI-based programs to work properly. Failure to load a plugin because of unresolved symbols is now always reported on the terminal. Another script 'squeak.sh' is provided for launching squeak from a menu. This isn't finished and suggestions are welcome. Default path and text encoding is now UTF-8. X11 driver no longer reports SHIFT pressed when CAPS LOCK engaged. SerialPlugin now supports named ports. All occurences of dprintf() renamed to avoid a name conflict with a less-than-stellar decision by POSIX to introduce a standard function of the same name. RomePlugin is no longer built if cairo was built without Pango support. iconv_open() no longer spams you with thousands of error messages if you are missing conversion tables. Valid unicode characters that have no corresponding keycode are reported with keycode zero to avoid an invalid index error in the image. XImmPlugin should now work on MacOS X/Darwin too. Sound driver on MacOS X now works on Intel as well as PowerPC. Various changes to make the VM compile and run on GNU/Linux running on DEC Alpha. vm-sound-Sun now uses asynchronous i/o. Various changes to fix compilation on Solaris.

This is work I did for VisualWorks a while back. The idea is to add a set of mirror primitives, so called because they do reflection, to ContextPart. These primitives implement the basic operations of the object model needed for execution simulation, fetching an object's class, accessing its named and indexed instance variables, and the number of indexed instance variables, sending a message, but they take the object operated on as a parameter and so do function without sending messages to that object. These primitives are then used by the execution simulation machinery to correctly simulate the execution of the virtual machine irrespective of the class and/or messages implemented by the receiver. For example, (eschewing HTML for Bert's contentment) ContextPart methods for mirror primitives object: anObject instVarAt: anIndex "Primitive. Answer a fixed variable in an object. The numbering of the variables corresponds to the named instance variables. Fail if the index is not an Integer or is not the index of a fixed variable. Essential for the debugger. See Object documentation whatIsAPrimitive." <primitive: 73> "Access beyond fixed variables." ^self object: anObject basicAt: anIndex - (self objectClass: anObject) instSize object: anObject instVarAt: anIndex put: aValue "Primitive. Store a value into a fixed variable in the argument anObject. The numbering of the variables corresponds to the named instance variables. Fail if the index is not an Integer or is not the index of a fixed variable. Answer the value stored as the result. Using this message violates the principle that each object has sovereign control over the storing of values into its instance variables. Essential for the debugger. See Object documentation whatIsAPrimitive." <primitive: 74> "Access beyond fixed fields" ^self object: anObject basicAt: anIndex - (self objectClass: anObject) instSize put: aValue ContextPart methods for instruction decoding pushReceiverVariable: offset "Simulate the action of bytecode that pushes the contents of the receiver's instance variable whose index is the argument, index, on the top of the stack." self push: (self object: self receiver instVarAt: offset + 1) popIntoReceiverVariable: offset "Simulate the action of bytecode that removes the top of the stack and stores it into an instance variable of my receiver." self object: self receiver instVarAt: offset + 1 put: self pop storeIntoReceiverVariable: offset "Simulate the action of bytecode that stores the top of the stack into an instance variable of my receiver." self object: self receiver instVarAt: offset + 1 put: self top The attached change set for the image level code is also conflated with changes that allow the debugger to set the primitive error code correctly. The VM also needs to implement the primitives. If the order of the arguments are the same as those of the corresponding non-reflective primitive (e.g. aContext object: theReceiver instVarAt: index put: value has the same order as theReceiver instVarAt: index put: value) and the primitive pops back the stack using self pop: argumentCount + 1, one can use the same VM primitive implementations as the non-reflective ones and so avoid needing extra primitives. However, not all primitives are correctly implemented; e.g. at: and at:put: are, but size is not. So before we can use this there is some work to do in the standard VMs. I'm attaching here the implementation in the Stack VM which will require some back porting to the standard VM. None of these changes has performance implications because the special selector impelmentations of at: at:put: size and #== are not affected. With the above changes one can safely step through code that uses proxies that do not inherit from Object, or even ProtoObject. I still need to implement a PrimitiveObjectInspector, or use the mirror primitives in implementing the Inspector. However, there is one more important thing needed in the debugger which these changes do not address and that is the value of Processor activeProcess within the debugger. e.g. "print it" the following: | thisProcessOutsideTheDebugger thisProcessInsideTheDebugger | thisProcessOutsideTheDebugger := Processor activeProcess. self halt. thisProcessInsideTheDebugger := Processor activeProcess. 'Send to here (Into) then proceed'. thisProcessOutsideTheDebugger == thisProcessInsideTheDebugger This will potentially break debugging of servers that maintain process pools. Andreas has proposed a very simple fix for this. Add an instance variable to Process called, e.g. effectiveProcess, which is nil in normal processes. When the debugger runs it sets effectiveProcess to that of the process which it is debugging and Processor activeProcess is implemented as something like ProcessorScheduler methods for accessing activeProcess ^activeProcess effectiveProcess ifNil: [activeProcess] I'll try and get round to this soon. I'm posting this rather than integrating because a) the VMs need to get updated before we can use the image level code and, b) the VM folks need code to test their VMs with. I'm happy to integrate the image-level changes once the VMs have been upgraded. best Eliot > > > > > - Bert - > > > > > -- > Best regards, > Igor Stasenko AKA sig. >

Compiling unix VM
by Ricardo Moran 29 Sep '09

29 Sep '09

Hi, I'm trying to build the unix squeak vm to test the serial plugin fixes and I'm having some problems. This is the first time I try to compile a vm and I'm not really used to the Linux environment (I'm a windows user, sorry :P) so I'll be asking some newbie questions. I attached what I could copy from the terminal, I hope this helps. First of all, I followed the instructions from here: http://www.squeakvm.org/unix/platforms/unix/doc/HowToBuildFromSource.html/H… but using platforms/unix/cmake/configure instead of platforms/unix/config/configure (as advised by David T. Lewis). After that (I think it finished ok) I ran /usr/local/bin/squeak.sh and it asked me to choose an image. I tried an updated Squeak trunk image, an etoys-dev-4.0, the etoys.image from Etoys4-RC-ToGo but nothing happened. Then I tried to use the new vm and plugins with the Etoys-ToGo package. I'm guessing the new vm and the plugins are installed at /usr/local/lib/squeak/3.11.3-2142/ so I replaced the Linux vm files in Etoys-ToGo with these new ones. This doesn't work either. Finally, I tried to run squeak by typing squeak in the terminal and I got this error: SQUEAK_ENCODING='UTF-8' SQUEAK_PATHENC='UTF-8' SQUEAK_PLUGINS='/usr/local/lib/squeak/3.11.3-2142' + exec /usr/local/lib/squeak/3.11.3-2142/squeakvm could not find display driver vm-display-X11; either: - check that /usr/local/lib/squeak/3.11.3-2142/vm-display-X11.so exists, or - use the '-plugins <path>' option to tell me where it is, or - remove DISPLAY from your environment. Aborted As it says in the error message, the file /usr/local/lib/squeak/3.11.3-2142/vm-display-X11.so does not exist. I don't know why though. I must be doing a lot of things wrong but I don't know what to try next. I would really appreciate some help here. Thanks in advance. Richo

Input semaphore?
by Michael Rueger 28 Sep '09

28 Sep '09

Hi all, reviving a discussion/question from a while ago: IIRC both Linux and Mac VMs signal the input semaphore for input events, but the Windows VM still doesn't? Can't find the mail right now, but I think Andreas mentioned it would be easy to fix? Would help with non-polling UI frameworks :-) Michael
