finding the latest vm dir on linux
by tim Rowledge 01 Aug '16

01 Aug '16

I need some shell script help for the upcoming Pi release; we’ve recently changed how the vm directory is named, from /usr/lib/squeak/5.0-abcd 4-digit svn update number based to /usr/lib/squeak/5.0-2016…. date-of-something-in-iso based. Clearly a naive `ls /usr/lib/squeak/5.0-*/squeak | sort -r | head -1` isn’t going to be helpful if we happen to have an older directory as well as a recent one. So, how does one discriminate effectively? I’ve considered maybe searching for 5.0-20* so we ‘limit’ ourselves to vms from this century :-) Any neater ways? Is there a way to drop 4-or-less-digit results? Some other magic? tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Strange OpCodes: RIW: Re-Invent Wheel

Cuis Spur preview
by Juan Vuletich 01 Aug '16

01 Aug '16

Hi Eliot, Folks, Eliot and I have been been working a bit, over some time, to make Cuis compatible with the Spur VMs. We prepared together the changes required to make the Cuis image ready for the Spur bootstrap process (also used for Newspeak, Squeak and Pharo). Eliot made any necessary changes to the Spur bootstrap to also handle Cuis. (Eliot, you might want to give additional details on what was required here?). The result of the Spur bootstrap was a Cuis image that could start, but could do little else. Compiler and Decompiler were broken, so fixing was hard. Then I came with the idea of doing the same I did when converting Cuis to Closures: Have two Compilers loaded, and switch between them easily. So, I added the necessary changesets to the "PreSpurBootstrap" stage, adding a verbatim copy of Squeak's Compiler, and making it active. The result of the Spur bootstrap was now a Cuis image that could not only start, but also browse and modify code. There were still many rough edges, but now they can be fixed from within the image, as we usually do. I fixed the most obvious ones, as part of "PostSpurBootstrap". The resulting image is available at https://www.dropbox.com/sh/45vub8hnq1riq10/AADDKBWsIvPfUNqjuz91PW7Ra/CuisSp… . The "PreSpurBootstrap" and "PostSpurBootstrap" changesets are there too, meaning that anybody can reproduce the procedure, and suggest fixes and enhancements. This is not yet good enough to be added to the Cuis update stream. These are some of the things that are missing: - Merge both Compilers into just one, that handles Cuis specific details correctly, but also includes any updates required for Spur. - Check Decompiler. Decompile and recompile the code for all the system. - Make the very same source code for the whole system work both for V3 and Spur images. To build the Spur Cuis image, at the correct update number, the image is converted to Spur, and then run with a Spur VM, and the following updates are applied. To build a V3 image, the image is never converted to spur, and the very same updates are applied, always running with a non-Spur VM. This is not currently working, but I think it is possible, and allows both Spur and non-Spur Cuis images without forking. - Check that optional packages work. - Enable SmallFloat64, both as result of arithmetic, but also as literals in methods. - Many details I'm not remembering right now, or I'm not aware of. Eliot, let me than you for your wonderful work on Cog, Spur and Sista, for supporting Cuis along with the other OpenSmalltalk systems, and for guiding and encouraging me to keep Cuis up to date with latest VM technology. Cheers, -- Juan Vuletich www.cuis-smalltalk.org https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev @JuanVuletich

Marking VMs as "stable"
by marcel.taeumel 01 Aug '16

01 Aug '16

Hi, there. Could some please tag some VM version as "stable" so that we have the first candidate to be used in the Squeak release artifact packaging process? :-) I don't want to package any latest "bleeding edge" VM build into those artifacts. Thanks, Marcel -- View this message in context: http://forum.world.st/Marking-VMs-as-stable-tp4908814.html Sent from the Squeak VM mailing list archive at Nabble.com.

Fwd: [Pharo-dev] Error: cannot create OS pipe
by Max Leske 28 Jul '16

Forward to vm-dev. > Begin forwarded message: > > From: "J.F. Rick" <self(a)je77.com> > Subject: [Pharo-dev] Error: cannot create OS pipe > Date: 28 July 2016 at 17:51:51 GMT+2 > To: Pharo Development List <pharo-dev(a)lists.pharo.org> > Reply-To: Pharo Development List <pharo-dev(a)lists.pharo.org> > > I've been using CommandShell for some operations on OSX with Pharo5. After doing a number of "PipeableOSProcess command:" calls (~150), I get an error inside ExternalPipe:makePipe. For my purposes, I can get around this by restarting Pharo and limiting the number of operations each session. But, it is an indication that some resource is not getting freed when the PipeableOSProcess is deleted (garbage collected). I just thought I'd mention the bug. > > Cheers, > > Jeff
