It can be another > bug of wrong startup order > Maybe a problem on the image and the vm side. Even in headless mode, starting pharo creates a window. Even if it is hidden, it has some size. Quit and Saving an image will write the current width/height into the image file. Starting the vm will create a window and set the size of the window to the last size. The window is always created in normal (not-maximized) mode and the available size is a little bit smaller than for a maximized window. Now, the image checks for a change of the size of the current DisplayScreen instance and the actual screen size. If this is different (as in this case) a new DisplayScreen is initialized which will call a full screen update (ioForceDisplayUpdate). And this method will show a hidden (headless) image. > > >> >> On Fri, Dec 29, 2017 at 6:22 AM, phil(a)highoctane.be <phil(a)highoctane.be> >> wrote: >> >>> I am using nssm because the service option is broken. >>> >>> The code seems to still be in the image but disabled (there are quite a >>> few things like that actually). >>> >>> Phil >>> >>> >>> On Fri, Dec 29, 2017 at 11:59 AM, Torsten Bergmann <astares(a)gmx.de> >>> wrote: >>> >>>> >>>> Hi, (cross posting vm-dev) >>>> >>>> nssm is nice - but requires additional tools. >>>> >>>> Since the days of Squeak the windows VM had the >>>> >>>> -service "ServiceName" >>>> >>>> option and one was able to run Squeak as a windows service out of the >>>> box. >>>> >>>> See http://wiki.squeak.org/squeak/105 for details. >>>> >>>> This option allows to register/deregister with the windows service >>>> manager and run >>>> a headless image. >>>> >>>> I run a Squeak Wiki (Swiki/Comanche) since years with this and it is >>>> very nice and stable. >>>> >>>> Unfortunately this is broken in recent Pharo VMs and so far Esteban or >>>> others did not >>>> have the time to look into this issue.

Assuming 1 image = 1 user? In Pharo 7: FileLocator workingDirectory = C getcwd() # same as R and most languages FileLocator imageDirectory = the directory where the image is located FileLocator vmDirectory = the directory where the vm is located + several others FileLocator class>>workingDirectory: (i.e. setwd()) doesn't exist, but is straightforward to add. Pharo 6 has the same, but workingDirectory = imageDirectory. Cheers, Alistair

Re: [Pharo-users] unsolicited package-cache use

How can I outsource instance data ?

by Photon

Hello, I am messing around with an ordered collection of a class wich contains a matrix. As it the size grew I started to wonder if my code was something one should not do or if one would maybe outsource some data. I don`t know if it`s just in the RAM if iI start the VM. In that case i would overkill it at some point or not? So i thought of storing the data on harddrive to be able to recall it later when I need to but get it out of the running VM for the moment. Maybe you can enlighten me regarding this. In this picture you can see that my data is basicly stored inside of a inspector at the moment. So it would be cool to store the whole thing on harddrive. <http://forum.world.st/file/t371759/inspector.png> -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
