> When the "PythonImport" directive is used, mod_python uses the "PyImport_ImportModule()" function to import the specified module. If that same module is later imported using the "apache.import_module()" function, it will be reloaded a second time even though the Python module file hadn't changed and even if "PythonAutoReload" is set to "Off".
> This reloading can cause problems if the module when loaded using PythonImport had setup resources such as database connections etc. This is because "apache.import_module()" will effectively throw away the existing values
> and replace them. This can be an issue if the resources aren't deleted properly and hold open stuff like socket connections with those connections no longer being accessible or useable.
> The basic problem here is the mixing of standard Python import mechanism and any system implemented by mod_python. The best solution now and in the future, would be for the "PythonImport" directive to use the "apache.import_module()" function to import any modules. That way it would be ensured they always work together properly and not against each other.
> Note that this problem was previously catalogued as ISSUE 17 on my list of mod_python module importing problems. This list of problems can be found at:
