Developing and testing on Windows 7, created Sublime Text 3 plugin and opened subprocess:

proc = subprocess.Popen("node" , myJSFile], cwd=dirname, bufsize=-1, stdout=subprocess.PIPE , stderr=subprocess.PIPE , shell=True , universal_newlines=True)

NB: I need the shell=true.
Subprocess runs nicely but when I try to kill it by sending it SIGTERM:

os.kill(proc.pid , signal.SIGTERM)

I get the following error:

Traceback (most recent call last): File "D:\Portable\Sublime Text 3\sublime_plugin.py", line 549, in run_ return self.run(edit) File "D:\Portable\Sublime Text 3\Data\Packages\NodeRunner\NodeRunner.py", line 50, in run terminateNode(entryPoint) File "D:\Portable\Sublime Text 3\Data\Packages\NodeRunner\NodeRunner.py", line 98, in terminateNode os.kill(proc.pid , signal.SIGTERM) PermissionError: [WinError 5] Access is denied

Currently, I can kill the process with:

subprocess.Popen("taskkill /F /T /PID %i"%proc.pid , shell=True)

But I dont like this brute force solution as my process does not get proper sigterm signal for post operations.

I have read lot of google topics about the subject but with no success. Does anyone have any ideas how to solve?
