Terminate a process in a Win32Shell
 
|
Hi all,
I have one squeak image bring up another squeak image to run a script. I have the following code in my workspace. shell1 := Win32Shell new. t := [s := shell1 shellExecute:f lpOperation:'open' lpFile:'Squeak.exe' lpParameters:'Squeak3.10.2-7179-basic.image project-files/testNone.sh none' lpDirectory:'' nShowCmd:1.] . r = t fork. I wish to be able to kill the squeak.exe process being run from the shell. r terminate does not seem to do that. Any pointers to what I should use. Thanks in advance. Arushi |

Hi Arushi,
> r = t fork. Even if you corrected this assignment, you would only have a Smalltalk "Process" object, which only terminates processes running in or above the interpreter; they have nothing to do with OS processes. To control OS processes, check out OSProcess. As an alternative, you may wish to exit the other image gracefully. - Chris On Tue, Apr 13, 2010 at 9:16 PM, Arushi Aggarwal <[hidden email]> wrote: > Hi all, > > I have one squeak image bring up another squeak image to run a script. > I have the following code in my workspace. > > shell1 := Win32Shell new. > t := [s := shell1 shellExecute:f lpOperation:'open' > lpFile:'Squeak.exe' lpParameters:'Squeak3.10.2-7179-basic.image > project-files/testNone.sh none' lpDirectory:'' nShowCmd:1.] . > > r = t fork. > > I wish to be able to kill the squeak.exe process being run from the shell. > > r terminate does not seem to do that. > > Any pointers to what I should use. > > Thanks in advance. > > Arushi > > |

The OSProcessPlugin for Windows is not distributed with the VM, so you would need to build your own if you want to do this. With the plugin in place, you can start external processes and terminate them with #terminate as you would expect. To build the plugin you need the OSProcessPlugin and VMMaker packages from http://squeaksource.com. Dave |

I got OSProcessPluginV4-3-7.sar and the VMMakerPackage. The VMMaker does not list OSProcessPlugin as an available Plugin. How do I make it so/what file is it missing? > > Dave > > > |

The home page is http://wiki.squeak.org/squeak/3349. You can use the SAR file from that page, but it is better to go to http:squeaksource.com and get the latest version of the package in "OSProcessPlugin". Once you have loaded this, you should be able to open a VMMaker window and find Win32OSProcessPlugin as an available plugin. Follow the normal instructions for building on Windows (http://squeakvm.org/win32/compiling.html), with the following two notes: 1) OSProcessPlugin (OSPP) requires two header files: platforms\Cross\plugins\FilePlugin\FilePlugin.h platforms\Cross\plugins\SocketPlugin\FilePlugin.h The normal Makefile probably will not find these, so you can either fix your makefile to find them, or just copy them somewhere where they will be included. 2) Some OSPP functions will not work (opening stdout, console, etc) on Windows unless you make changes to the file handle registry in platforms\win32\vm\sqWin32HandleTable.h.
