I have not read about this anywhere I can remember. Would it be possible to run two images on one VM? Preggo, Robertotini Sent from ProtonMail Mobile

[OpenSmalltalk/opensmalltalk-vm] new Sun pull request (#494)
by David Stes 01 May '20

01 May '20

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 I've made some changes to support Solaris / SunOS. First of all, I've removed my modification of the "default" pulseaudio choice in the case of #if sun; the reason is that there was concern about this on other platforms. And additionally it is possible to setup the Solaris build environment so that the header files soundcard.h sys/soundcard.h and sys/audioio.h are not found (are absent). In that case the configure script will think it does not have build OSS audio and Sun modules, and the only module that will be built is "vm-sound-pulse". So the system will load the only module available : pulseaudio. So no change is really required to get the result that "pulseaudio" is now the default on Solaris. Please have a look at the proposed changes on the "sun" branch and hopefully this can be integrated.

Looking for a new VM release candidate (was: [squeak-dev] Broken 5.3 downloads need fixing)
by Marcel Taeumel 30 Apr '20

30 Apr '20

Hi Tim! Yes, let's make a new VM release to be used in Squeak 5.3 and 6.0alpha. I think we should start this dicussion on vm-dev, so I cross-post this. Once we find a new candidate that was build after March 24 to fix the ARM bug you mentioned, we can update the CI and the bundles. (https://github.com/OpenSmalltalk/opensmalltalk-vm/releases [https://github.com/OpenSmalltalk/opensmalltalk-vm/releases]) That new release will then be copied over to the CI's base files: http://files.squeak.org/base/ [http://files.squeak.org/base/] Once the new bundles are produced... http://files.squeak.org/5.3/ [http://files.squeak.org/5.3/] http://files.squeak.org/6.0alpha/ [http://files.squeak.org/6.0alpha/] ...we can update squeak.org. But first things first: We need to find a new release candidate for the VM to be tested at least a week. Tim proposed the following version: 202003291024 Eliot? Nicolas? Any thoughts on this? Best, Marcel Am 18.04.2020 01:43:32 schrieb tim Rowledge <tim(a)rowledge.org>: The VM included in the 5.3 package for the ARM linux systems is fatally broken due to a code generator bug; we had various discussions about the issue in mid-March. We also noticed a problem with the bitBLT code for all platforms that was fixed by VMMaker.oscog-nice.2732 We really need to push the magic buttons to replace the ARM package in order for it to run at all; updating the other platforms to fix bitBLT would be nice. A quick test of the next available VM on bintray suggests that the https://bintray.com/opensmalltalk/vm/download_file?file_path=squeak.cog.spu… version is functional - but maybe we want to use the latest? What needs doing to solve this for the download page? tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Useful random insult:- On permanent leave of absence from his senses.

ucontext.h or sys/ucontext.h
by stes 30 Apr '20

30 Apr '20

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Minor technical issue. Regarding platforms/unix/vm/include_ucontext.h Solaris has a #include <sys/ucontext.h> so the build was working, but some versions adhere to the "Single Unix Specification v2" (SUS v2). According to some info (I'm no expert in this) this is Solaris 7/8 SUSv2 superset of SUS extended Solaris 7 to support POSIX.1b-1993, POSIX.1c-1996, and ISO/IEC 9899 (C Standard) Amendment 1 Now that standard speficies that you can #include <ucontext.h> instead of #include <sys/ucontext.h> Also see https://pubs.opengroup.org/onlinepubs/7908799/xsh/ucontext.h.html I've added a small #ifdef __sun fix to use #include <ucontext.h> in the Solaris case. Alternatively perhaps the configure script could check for the existence of the <ucontext.h> header file ... Unfortunately the #include's that the program issues, does have obviously major impact on the behaviour of the VM. Another issue one of the fixes I submitted in the sunos branch is or was : # include <sys/file.h> /* FASYNC or ioctl FIOASYNC will be issued */ in the file platforms/unix/vm/aio.c The issue there (completely unrelated to the ucontext.h issue) is that that header file determines how the code in aio.c works Because in aio.c there is code #if defined(O_ASYNC) #elif defined(FASYNC) #elif defined(FIOASYNC) great care about the configuration of header files (#include) is needed. Perhaps also in the case of aio.c this could be dealt with in the configure script. The configure script could also in that case try to figure out what the correct #include is, but it has major impact of course on the behavior of the VM ...

How to create headless VM without some primitives?
by Erik Stel 30 Apr '20

30 Apr '20

Hi, I'd like to create a headless VM without some primitives. I want a VM without file support and without FFI support (for example). The idea is to be able to run the image in a kind of sandboxed environment without the risk of reaching (at least some of) the OS from code. The only interface should probably be the network. How would I go about creating such a VM? Should I 'simply' use the existing VM build scripts and configure it such that no unwanted primitives are compiled? Or do I need to change the VM-Maker? Any pointers are welcome! Thx for any advice! Regards, Erik -- Sent from: http://forum.world.st/Squeak-VM-f104410.html
