Distinguish between pserve and pshell in main

[Martin Stein]

Hi all,

is there an elegant way in the central main(..)-function to determine if the application was started from pserve or pshell? I'm launching a background thread from there, which does some regular polling of a 3rd-party API. Obviously I don't want to start that thread when the application is launched from pshell, but I don't see an easy way to prevent that.

Thanks and best regards,
Martin

You could check which modules are imported... the pserve script is loading stuff from paste.deploy so these modules
should be present in sys.modules

Don't know if it's elegant but sys.argv[0].endswith('pshell') is true when you are using pshell

I like the sys.argv[0]-approach: It's simple and readable. Should have thought of it myself.
And longer term I should probably switch to an approach with a separate daemonized process (using Pyramid's command-line helpers).

Thanks both of you.
