Re: [Pharo-dev] How can I save changes on memory ?

by Ron Teitelbaum

Hi JÃ©rÃ©mie, Welcome to Pharo. There are a number of different types of memory so it's difficult to answer your question. The first big divide is Development vs Production. in Development you create code that is stored in a repository. Your changes can also be captured in a change set, or automatically in the changes file. When you create a new class it creates a change which will go to the changes file. You can get back your code by selecting World > Tools... > Recover lost changes. See http://files.pharo.org/books-pdfs/updated-pharo-by-example/2017-01-14-Updat…. It may also add your code to a change set. See "Change sets and the change sorter" in the same link. You might also save code in a Monticello Repository, or even have your files written into a Git repository. Once you have your code written and saved in a repository you can create a production image for your users. That process usually requires that you use a base image, load your changes and save the image. It might also include locking down the image, turning off developer tools, and packaging it in an installer. At that point, you can send your classes and methods to others to use as an application. You could also deploy your Pharo image as a server on your computer and allow users to interact with it using other methods like http or tcp. There is a third method to save modifications in memory during runtime. The basic way to do that is to just create instances from your classes (MyClass new) add your data and execute your methods and save the image, or write out the data to a database or file so that those instances can later be read in and recreated by your program. In that way, your program saves its state and can reload it later in memory. It's not clear from your question what type of memory or program you are talking about. Good luck with your programming, hopefully, that will be helpful!

The problem is that stable VM crashes every 10min when I type (the same problem as Doru has) and latest is slooooow. My current crash.dmp is already 934 KB while single typing related crash produces 8 KB of output.

Hi Eliot, I experience the same slowness as Cyril. Latest Pharo's UI is completely unresponsive and it takes seconds to open new windows, resizing is a nightmare. I made two videos comparing latest and stable VMs. I used 32bit Pharo-60501 on OSX Sierra 10.12.5. â Pharo-VMLatest.mov <https://drive.google.com/file/d/0B-bMBVDOi3oTXy1wNmlSTlV5THM/view?usp=drive…> ââ Pharo-VMStable.mov <https://drive.google.com/file/d/0B-bMBVDOi3oTX3AzUkNqcng3dUk/view?usp=drive…> â Cheers, Alex On 20 June 2017 at 19:14, Eliot Miranda <eliot.miranda(a)gmail.com> wrote: > Hi Cyril, > > On Tue, Jun 20, 2017 at 8:08 AM, Cyril Ferlicot <cyril.ferlicot(a)gmail.com> > wrote: > >> On Tue, Jun 20, 2017 at 5:04 PM, Eliot Miranda <eliot.miranda(a)gmail.com> >> wrote: >> > Hi ClÃ©ment >> > >> > >> > That was a mistake of mine.

Ok. Maybe when things are fixed we should update the Pharo 6 release version (the one-click) to have a version with OSProcess working. Cyril the production Pharo VM are now generated from opensmalltalk-vm. There is no separate Pharo build. Just saying to avoid fireworks.

Hell, I think the newest VM already has a fix to work like before, so no change the OSProcess is needed: https://pharo.fogbugz.com/f/cases/20156/OSPlatform-current-returns-a-MacOSP… <https://pharo.fogbugz.com/f/cases/20156/OSPlatform-current-returns-a-MacOSP…> > On 20 Jun 2017, at 15:10, ClÃ©ment Bera <bera.clement(a)gmail.com> wrote: > > Hi Thierry, hi all, > > The Pharo catalog version of OSProcess is not working in the Pharo 6 release and I need to load OSProcess in one of my projects.

Working OSProcess configuration for Pharo 6 release (please)

by ClÃ©ment Bera

Hi Thierry, hi all, The Pharo catalog version of OSProcess is not working in the Pharo 6 release and I need to load OSProcess in one of my projects. I cannot load OSSubProcess instead, so no need to answer this mail talking about it. In-between version 2231 and 2241 of VMMaker, the vm parameter 1002 (os version), has changed on Mac from '1011.6' to '10.11.6'. OSProcess tests the version number against 1000, and should now test against 10. I checked the SqueakSource repo of OSProcess, I can see that the last version is 4.6.8 and the catalog configuration loads an older version, but I cannot see any fix related to the version number ? Can someone update the OSProcess configuration in the Pharo catalog so that it loads a working version in the Pharo 6 release or point me to an OSProcess configuration, outside of the catalog, which works in the release of Pharo 6 please ? Thank you very much. Clement
