Executing doit repeatedly, delayedTasks are only executed once(?)

[Holger Bruch]

I'm trying to run doit via a schedule every n seconds. However, a delayed task is only executed for the first time. How could I reset doit to recreate the task on each run?

Thx, Holger

Example:

run_doit_in_loop.py:

import schedule

import time

from doit.doit_cmd import DoitMain

def run_doit():

    print("run doit")

    DoitMain().run("")

schedule.every(1).seconds.do(run_doit)

while True:

    schedule.run_pending()

    time.sleep(1)

dodo.py:

from doit import create_after

def task_a():

return {'actions': ['echo a']}

@create_after(executed='a')

def task_b():

return {'actions': ['echo b']}

Output:

run doit

.  a

.  b

run doit

.  a

run doit

.  a

...

Hi,

It is a bug. Normally doit is not executed repeatedly in the same process. Might need more fixes...

The "create_after" decorator attaches some info to the function object and it is also used to track the task creation.

Following diff fixes it:

Can you please create an issue on github so this dont get lost.
