Can't stop processes

[pscholze]

Running 4.2.0 on Windows 10. When trying to stop a process, I get following error. Same problem using TERM and INT as stopsignal. Defining KILL is not accepted.

supervisor> stop phonebook
FAILED: unknown problem killing phonebook (15152):Traceback (most recent call last):
  File "C:\Program Files\Python36\lib\site-packages\supervisor\process.py", line 599, in kill

    self.pidhistory[pid].process.send_signal(sig)
KeyError: -15152

Which version of python ? I will need the settings used in superviosor.conf.

[pscholze]

Python 3.6.8

supervisor.conf:

[inet_http_server]    
port=*:9001       

[supervisord]
logfile=D:\build\supervisor\supervisord.log 
logfile_maxbytes=50MB
logfile_backups=10
loglevel=info
pidfile=D:\build\supervisor\supervisord.pid
nodaemon=false
minfds=1024
minprocs=200

[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]

[include]
files = D:\build\supervisor\config\*.ini

[alexsilva]

The process settings were missing but was the option 'killasgroup' configured ?

[pscholze]

Yes. killasgroup is set true.

[alexsilva]

Update your version of the supervisor and see if the problem is resolved

python -m pip install git+https://github.com/alexsilva/supervisor.git@windows -U

[pscholze]

With updated version:

supervisor> stop phonebook

    output = self.pidhistory[abs(pid)].process.kill2(pid, sig)
  File "C:\Program Files\Python36\lib\site-packages\supervisor\helpers.py", line 48, in kill2

You can enter the supervisor log and the phonebook process settings ?

[pscholze]

Process INI:

[program:phonebook]
command=cmd.exe /c "mycommand"
stdout_logfile=D:\build\supervisor\logs\%(program_name)s.log
stdout_logfile_maxbytes=50MB
redirect_stderr=true
environment=BUILD_LOG="C:\log"
stopasgroup=true
killasgroup=true
stopsignal=TERM
stopwaitsecs=30

phonebook something in that process prevents it from being stopped. I was unable to identify the problem because it is beyond the supervisor himself. It may be permission, some protection from the process itself. Even the task manager is unable to stop it!

[alexsilva]

Have you tried testing other simpler commands ? Like:

[program:cmd]
command=cmd.exe /c ping www.google.com -t
stdout_logfile=D:\build\supervisor\logs\%(program_name)s.log
stdout_logfile_maxbytes=50MB
redirect_stderr=true
environment=BUILD_LOG="C:\log"
stopasgroup=true
killasgroup=true
stopsignal=TERM
stopwaitsecs=30

"mycommand" is only a dummy command due to legal restrictions on the part of our customer. When I start the process in a python script with subprocess.Popen and stop it and its children using SIGTERM, all works fine ...

[alexsilva]

This version of the supervisor starts the process with subprocess.Popen as well. I see no reason why it won't work.

#L380

Try disabling these options. They change the behavior of stopping a process.

stopasgroup=false killasgroup=false

[alexsilva]

@pscholze I made recent changes in the execution and management of processes. I suggest you update and run new tests.

Closing due to inactivity and lack of response.
