Python documentation is not up to date :)

Hi,

The example given in the documentation ( http://www.smartfoxserver.com/docs/inde ... python.htm ) about "importing module" and the destroy method does not work.

I get a NameError.

Because we do the import in the local scope of init() so we can't see the sys modules in the global scope and in the destroy scope... (erf there is too much scope )

So you have to add in init() "global sys" and idem in destroy() and all will work fine

Yes, that's correct.
Actually the import code should be done outside of the init() method.
I will make sure that the example is updated.

Thanks for noticing

I'm trying to manipulate my path in a python module. I do the following at the top of my python module, outside of the init() function:

Code: Select all

import os, sys 
sys.path.append(os.getcwd())

And it gives me the following traceback, for some reason:

Code: Select all

Traceback (innermost last):
  File "<string>", line 795, in ?
NameError: sys

I'm not really sure if this is a Jython-related problem or what. If I do this inside the init() function it seems to work ok. Any suggestions? I want to be able to import other python modules from the sfsExtensions directory, and have them available to all of my functions (in the global namespace).

[Lapo]

That's strange, which SFS version do you use?
Maybe you have altered the classpath, but I can't be sure.

[ThierryStiegler]

I get the same issue, I use the latest version 1.6.5.

[icepick]

I get the same issue, I use the latest version 1.6.5.

Glad it's not just me! Or maybe not, since this probably indicates that it's more difficult to fix. I am using 1.6.2, was going to upgrade to 1.6.5 but looks like that won't solve it.

[icepick]

Very weird... I added a comment at the top of the python module, and now it's working

So this works...

Code: Select all

  1 #foo
  2 import os, sys
  3 sys.path.append(os.getcwd())

...but this does not...

Code: Select all

  1 import os, sys
  2 sys.path.append(os.getcwd())

Hope that works for you as well, Thierry! Lapo, any idea why it behaves this way?

[ThierryStiegler]

hmmm normaly you have to set at the first line the right script interpreter #!/bin/bash

Myabe this an old spec of Python 2.2, don't forget that SFS use Jython 2.2 so...

I will try tomorow at office

Thnaks for sharing

[icepick]

I wouldn't think a shebang line or comment would be necessary, but my Python experience only goes back to 2.3, so maybe it is a 2.2 or Jython restriction. Either way, it's working for me now with just a comment there.

Hi there,
I think there's a small bug in the interpreter when it joins the server python library behind the scenes. A comment as the first line prevents the problem.
We'll fix it in the next release.

I continue here

I convert the Server Scheduler example in python. But I got a really little problem with a call of Scheduler.destroy().

It need one argument.

Here my fix :


scheduler.destroy( object() )

So it works

[Gnoll]

Try passing null,

Good luck,
Gnoll

[Lapo]

Code: Select all

scheduler.destroy(None)

[ThierryStiegler]

Why passing None ? Maybe this should be an optionnal arg ? no ?

[Lapo]

No, the init() and destroy() come from a parent interface which allows a parameter to be passed. In this case (the Scheduler) the parameter is not needed, so None (null) is the best thing.

(This is Java, so you have to pass an object when it's required )
