On ~/Squeak6.0-22104-32bit-202206021410-Linux-x86, **verifyCert:** attempts to match: 'squeak.org' with 'source.squeak.org' (and fails), on ~/Squeak6.0-22104-64bit-202206021410-Linux-x64 (with break point **verifyCert:** ) the match succeeds with both sides 'source.squeak.org'. Both run on the same Ubuntu 20.04.6 LTS (GNU/Linux 5.15.90.1-microsoft-standard-WSL2 x86_64); from dpkg -l => libxmlsec1-openssl:amd64 1.2.28-2; openssl:i386 1.1.1f-1ubuntu2.17; I don't know how to test this with wget. -- Reply to this email directly or view it on GitHub: https://github.com/OpenSmalltalk/opensmalltalk-vm/issues/663 You are receiving this because you are subscribed to this thread.

David T. Lewis uploaded a new version of VMMaker to project VM Maker: http://source.squeak.org/VMMaker/VMMaker-dtl.439.mcz ==================== Summary ==================== Name: VMMaker-dtl.439 Author: dtl Time: 15 April 2023, 7:19:26.846 pm UUID: 2c8ef6e2-8460-4120-b973-009902597787 Ancestors: VMMaker-dtl.438 VMMaker 4.20.5 Reorganize to bring the simulator back to life. Fix initialization of simulator classes to reflect separation of object memory from interpreter in the hierarchy. Move methods e.g. classFloat from ObjectMemory to Interpreter because they need to be referenced from plugins in simulation and are part of the InterpreterProxy protocol. Update FilePluginSimulator from oscog branch. Generated C code is unchanged except for minor update to FilePlugin (no functional impact for this VM). Note that opensmalltalk-vm (oscog branch) provides much better simulation support, but basic functionality needs to be maintained here as well. =============== Diff against VMMaker-dtl.438 =============== Item was changed: ----- Method: BitBltSimulator>>initialiseModule (in category 'initialize-release') ----- initialiseModule self class isInitialised ifFalse: [| ivars | ivars := #(opTable maskTable warpBitShiftTable ditherMatrix4x4 ditherThresholds16 ditherValues16 dither8Lookup). super initialiseModule. ivars do: [:symbol | self class instVarNamed: symbol put: (self instVarNamed: symbol)]. self class setInitialised]. opTable := self class opTable. maskTable := self class maskTable. warpBitShiftTable := self class warpBitShiftTable. ditherMatrix4x4 := self class ditherMatrix4x4. ditherThresholds16 := self class ditherThresholds16. ditherValues16 := self class ditherValues16. dither8Lookup := self class dither8Lookup. + ^true. + !

It also defines a number of handy object viewing methods to facilitate pawing around in the object memory. To see the thing actually run, you could (after backing up this image and changes), execute (InterpreterSimulator new openOn: Smalltalk imageName) test and be patient both to wait for things to happen, and to accept various things that may go wrong depending on how large or unusual your image may be.

A hybrid JS/WASM Squeak VM is running
by Craig Latta 15 Apr '23

15 Apr '23

Hi all-- I wrote a WebAssembly version of interpretOne() from the SqueakJS VM, and am now running it in that VM (very slowly for now, because it has to call other JS functions and manipulate JS memory). I've run the first several thousand instructions of resuming a Caffeine snapshot, and can switch back and forth between the JS and WASM versions of interpetOne() as the system runs. Over time, I can rewrite the other JS functions, and use WASM memory for the object memory. I'm looking forward to a big speedup, ultimately. I've already gotten some nice speedups from rewriting some of the inner BitBLT plugin functions in WASM. More details at [1]. cheers!
