how to schedule a job using tornado?

[aliane abdelouahab]

hi,
sorry for this queston ;)
here is the code:

if time = 18:00 pm, then print "hello"

so i guess, verifying time in a regular way, will consume ressources?
so do i use a separated thread only redicated to checking if it's time
to print "hello"? there is no shared ressources, since i use a
database call, that will post a message only at a given time.

is it possible?

Hi,

have you checked the documentation?

http://www.tornadoweb.org/documentation/ioloop.html

I think the timeouts section it's what you're looking for...

then i must use a special thread for listening to time and waiting
till the 18:00 gets? and do i receivre a confirmatio that the
operation has done correctly? because if i automate it, imagine that
at 17:59 there is a bug on the machine, and it will restarts at
18:01 !!!!

No threads. What about this (pseudocode):

add_timeout(datetime("when you want your operation to kick in") - datetime.now(), operation)

mmmmmmmmmm, it seems to be useful, but to be honest, i dident
understand... am a beginner and my mind works with blueprints (def
foo: print bar ).

IOLoop.instance().add_timeout( Time you want to time out in datetime type. )

and how it is behaving? do it control the time each X seconds? how
much this value X?

Check these out:

http://www.tornadoweb.org/documentation/_modules/tornado/ioloop.html#IOLoop.add_timeout

and

http://www.tornadoweb.org/documentation/_modules/tornado/ioloop.html#IOLoop.start

Timeouts are stored in a heap (self._timeouts). At each IOLoop iteration, the most urgent timeout is checked out from the heap and executed (if its time has come).

ah! so for each "Loop" time is checked!
thank you :)
