Re: [Vm-dev] VM Maker Inbox: VMMaker.oscog-dtl.2910.mcz
by David T. Lewis 25 Dec '20

This replaces VMMaker.oscog-dtl.2711 from the VMMaker inbox (9 February 2020), which I will move to treated. I merged the original submission, made a few changes, and added one new primitive based on earlier suggestions on vm-dev. This provides primitive support to allow the image to inform the VM that it can change the image format number from 68021 to 68533 after the image has been recompiled with SistaV1. It also provides a primitive for querying the VM for supported bytecode sets, such that this will work: Smalltalk supportedEncoders ==> {EncoderForV3 . EncoderForV3PlusClosures . EncoderForSistaV1} I am attaching a change set that illustrates the use of the two primitives. Dave

[OpenSmalltalk/opensmalltalk-vm] Error message for the failure to create heartbeat thread is too specific. (#540)
by Eliot Miranda 24 Dec '20

24 Dec '20

Hi, The warning/error pthread_setschedparam failed: Not owner is also happening on Solaris, and obviously it also prints some text, which does not really make sense on Solaris. I have documented on the following Wiki how to get rid of this warning/error on Solaris: https://sourceforge.net/p/solaris-squeak/wiki/Home/ I don't know how to fix the issue specifically on your Ubuntu distribution, but possibly it makes sense to - when the error happens - to print a simple: "error: pthread_setschedparam failed: Not owner or "error: heartbeat thread unable to run at higher priority" Such a simple short message would be sufficient, and then the user can try to do some research and find fixes for the specific platform, where the error happens. I can imagine that on various Unix flavors the instructions for: /etc/security/limits.d/squeak.conf do not apply. Also note that in my limited experience on Solaris, I can either fix the warning (by having threads run at different priorities) or ignore the warning, as it does not seem to make much difference ... But it's not nice that an extensive error message is printed, certainly not when it does not apply to that specific Unix distribution.

[OpenSmalltalk/opensmalltalk-vm] More manual cmake settings management (#543)
by Ben Coman 24 Dec '20

24 Dec '20

The previous WIP PR was copying the template file to "CMakeSettings.jsonx" (notice the x on the end). When changed to copy over actual user "CMakeSettings.json", Visual Studio was automatically re-parsing "CMakeSettings.json" and the info messages didn't get shown long enough to understand what was happening. So I believe copying the template over the user build settings will need to be a manual operation per this PR. You can view, comment on, or merge this pull request online at: https://github.com/OpenSmalltalk/opensmalltalk-vm/pull/543 -- Commit Summary -- * Use download_project to get libffi at configure time. * We cannot validate the class of a ByteString only, we need to check ByteSymbol and maybe there are others users of this. * Split FFI feature into FEATURE_FFI and FEATURE_THREADED_FFI * Fixing socket plugin options for OSX * Added Linux cmake helper * Merge branch 'feat/obs-packaging' of github.com:pharo-project/opensmalltalk-vm into feat/obs-packaging * Fixed types for Unix * The exception handle should be the last called, * Fix link to uuid on OSX * Merge remote-tracking branch 'origin/headless' into feat/obs-packaging * Fixes to restore cmake builds * Simplify windows build and make it the same as cygwin * Adding configuration to detect in which thread to show the exceptions * Adding filter for showing exceptions in windows.
