kevinconway / daemons Goto Github PK

(To be removed)

Hello, I am glad to have found your package after such a long time looking for something simple to run my Django app command inside as a daemon !

I was wondering if there is a way to use daemonizer decorator to stop the process ?

When I killed daemon process "python ShowMe.py" from OS,
I am triyng to start it again

python ShowMe.py start

and getting error

daemon.pid already exist. Cannot start daemon.

but process is dead!

so, I changed in start method

if pid is not None:
    message = "Pidfile %s already exist. Cannot start daemon."

to

if pid is not None and psutil.pid_exists(pid):
    message = "Pidfile %s already exist. Cannot start daemon."

psutil imported from https://github.com/giampaolo/psutil

On python 3, stopping the daemon raises an AttributeError (the simple daemon example on https://pypi.python.org/pypi/daemons will produce the error).

Traceback (most recent call last):
  File "/home/username/mydaemon.py", line 33, in <module>
    d.stop()
  File "/home/username/.local/lib/python3.5/site-packages/daemons/startstop/simple.py", line 81, in stop
    if "an integer is required" in err.message:
AttributeError: 'TypeError' object has no attribute 'message'

This is because Exception instances in python3 don't have the message attribute. It should probably be replaced with str(err).

I am trying to work with SimulaQron (https://github.com/SoftwareQuTech/SimulaQron) on my Windows. However, when I want to start it (via "simulaqron start") I run into the error "ValueError: invalid signal error". The error seems to result from daemons:

Therefore, I tried the example on https://github.com/kevinconway/daemons and this indeed gave the same error:

Here foo2.py is the second .py file as indicated in the example, so the one with "if __name__".

It seems to me that the problem is with pidfile. The value for pidfile in d = SleepyDaemon(pidfile=pidfile) is in my case:
C:\Users\Lynn\Documents\Capstone\testdaemon sleepy.pid
(Here, testdaemon is the directory in which the files of the example are stored.)

I am wondering if someone has an idea what is causing this problem. It would be great to fix this so that I (and others) could work with SimulaQron and daemons via Windows.
