To determine if -DONE_PROCESS was used on the command line,
noting that -X is equivalent to -DONE_PROCESS and -DNO_DETATCH,
one can use in the Apache configuration file:
<IfDefine ONE_PROCESS>
PythonEnablePdb On
</IfDefine>
As far as I can tell, the IfDefine directive uses the Apache C function:
ap_exists_config_define()
Ie., the defined symbol is the argument:
ap_exists_config_define("ONE_PROCESS")
Unless I am missing something, there is no equivalent to being able
to do IfDefine from within Python code executing inside of mod_python.
It sounds though that in this case with pdb that it might be a potentially
useful feature.
Thus, what do people think about a new function:
apache.exists_config_define(arg)
