Re: [Pharo-users] Externally signalling pharo VM for shutdown

by Sebastian Sastre

You can do it with kill -15 PID And, this (requires OSProcess): makeStopHook "Answers the process that hooks to the OS signal that makes this worker to shutdown when the VM process receives a TERM signal from the OS." ^ [|semaphore| semaphore := OSProcess accessor forwardSigTerm. semaphore wait. self onTerminationSignal] forkAt: Processor systemBackgroundPriority named: 'Image TERMâ onTerminationSignal "The process for the VM of this image has received a TERM signal from the OS. React accordingly" self log: 'That''s all folks. This worker is shutting down. Bye bye...' level:#messages. OSProcess accessor restoreSigTerm.

Depends on how you want the user to access the image. Using Seaside you could do something like whats described here: http://book.seaside.st/book/advanced/deployment/maintaining/requesthandler Esteban A.

Externally signalling pharo VM for shutdown

by Esteban A. Maringolo

Is there a way I can externally signal a running pharo-vm in order to request a shutdown equivalent to clicking on the close icon? I'd like to externally manage the start/stop of a Pharo image, but because the image can be used during development, I'd like to provide the user with a confirmation dialog instead of simply killing the process.

Well, it is not yet clear but at least, do not flatten all classes and keep packages.

recover lost changes

by Hartmut

To whom can answer me Working with Pharo 3.0 I noticed for a while that I could not recover class definitions (do it's) from the "Recent Changes". I also lost class comments on file-out / file-in . For the second problem I made the following test: 1. take a fresh Pharo 3.0 image (bundle for Mac OSX from Aug 29, 2014) 2. create MyClass with a class method and a comment. 3. file-out MyClass 4. remove MyClass on remove of MyClass I get an exception: https://www.dropbox.com/s/unq89t84tq7r60b/removeClass.tiff?dl=0 5. file-in MyClass The class is there - no error But: With the same exception in other images the comment is missing after file-in. Is this known? What does the exception mean? -- Hartmut Krasemannâ¨ KÃ¶nigsberger Str. 41 c â¨D 22869 Schenefeldâ¨ Tel. 040.8307097â¨ Mobil 0171.6451283â¨ krasemann(a)acm.org

This was interesting to know... The researchers at Inria published over 4,500 articles in 2013. They are behind over 300 active patents and 120 start-ups. cheers -ben On Tue, Feb 10, 2015 at 9:37 PM, Camille <camille.teruel(a)gmail.com> wrote: > Great! > > > On 10 Feb 2015, at 14:29, stepharo <stepharo(a)free.fr> wrote: > > > > > > > http://www.inria.fr/en/institute/recruitment/offers/phd/campaign-2015/%28vi… > > > > > > >

Re: [Pharo-users] Nautilus groups

by Ben Coman

I've never used the groups - mainly because I've never seen a sample workflow that I could copy, and my existing workflow is "sufficient" (which means I get a mess of windows plastered all over the screen as I follow sender&implementors, and could probably do better). btw, I've just spent 60 seconds trying to work out how to add an item to a group and could not. I don't even know what it groups - packages, classes, methods??? So I guess I ignored it, and once ignored, its a bit like that broken step in you building you always walk around without noticing. So discoverability of how to use it could be better, like something in the tooltip that "links" a more extensive tutorial on it, either in or out of image. cheers -ben On Tue, Feb 10, 2015 at 9:51 PM, Luc Fabresse <luc.fabresse(a)gmail.com> wrote: > Hi Christophe, > > > > 2015-02-10 14:28 GMT+01:00 Christophe Demarey <christophe.demarey(a)inria.fr > >: > >> Hello, >> >> We would like to know if some of you use Nautilus groups functionality: >> >> - dynamic groups: 'Last modified packages', 'Most viewed classes', >> 'Work' >> >> I do not use dynamic groups. > > >> >> - user defined groups : from the menu, you can flatten the content of >> many packages and get all classes into the newly created group. >> >> I do not like to flatten > > >> We have the feeling that it is not used (or not a lot) and we think to >> replace it with another mechanism (for example, let the user define his/her >> 'favorites' classes / packages). >> > > +1 > > I would prefer to be able to save a regular expression (the one I enter in > the text area above Package list) > > > Cheers, > > #Luc > > > >> >> Thanks for the feedback. >> >> >
