PharoLauncher problem starting images

[eilx2]

Every time I try to start an image from PharoLauncher I get the error:

"PrimitiveFailed: primite #isRunning in ProcessWrapper class failed"

Here is execution stack:

I tried installing the 1.3 version but it still isn't working.

Do you get this error with v1.4? x86 or x64 version? What is your environment? I guess Windows because of the use of ProcessWrapper but which version?

[eilx2]

Yes, it's the v1.4 and x64 version of windows. The problem went away after restarting the PC 2 times and it hasn't come back since.

[demarey]

Ok. Could it be an issue with memory (out of memory a some point)?

[JanBliznicenko]

This is probably not an issue with Launcher but with Pharo VM for Windows. Sometimes (seems quite random and affects only some users) Pharo does not get access to all libraries and only "fix" is to restart whole PC (which might or might not help - it is "random" whether you get it again). If Launcher gave you such error, you would get similar errors even if you opened any image without Launcher. Issue is most frequent on Windows 10.

I have a fix for this with a simple uffi wrapper for win32/CreateProcess that replaces ProcessWrapper. I use it in my PharoLauncher image. I'll tidy up a few things and make it public over the weekend.

Edit: still tidying up. It works perfectly fine, but some functions need to be in different classes, and the code managing processes needs to be built around a much clearer class.
