Re: [Jepp-users] jep.close() exits my application

[Tijs W. <Tij...@be...>]

Hi Fabrice,

I guess there are 2 options to solve this:

1)      Make all jep calls from the same thread, or

2)      Use the python threading module to wait for other threads

I use (and recommend) option 1.
For example, when run from an Eclipse plugin, I do all Jep calls from the gui thread:
Display.getDefault().asyncExec(new Runnable() {
                @Override
                public void run() {
                               StopPythonInterpreter();
                }
If you need background work, you can always use the python threading module to spawn a new python thread.
Before exiting jep, do your own python logic to ensure other threads are done ( a join() , or an Event(), whatever you want).

Hope this helps, cheers TW

Subject: [Jepp-users] jep.close() exits my application

Hello,

    I get the error "Fatal Python error: Py_EndInterpreter: thread still has a frame" when I try to call jep.close()
    I do not see what I'm doing wrong. On google it said that this comes from a test on tstate->frame != NULL in the native python library. The problem with this error is that my application is ended brutally.
    In my case, I'm running jep in a job but closing it by an action outside this job (graphical button).
    This does not occur in my other example which does not use a job.

    Does anyone know what is happening and if I must call some other jep method a clear things before closing it?

Regards,
Fabrice
