Graham Dumpleton updated MODPYTHON-160:
---------------------------------------

Version: 3.2.8
(was: 3.3)

Actually, one doesn't need to set req.handler as SetHandler/AddHandler in Ap
ache configuration will set up same scenario. Example given was actually doi
ng both when it should have been doing one or the other. As such, this probl
em can be triggered in mod_
python 3.2.8 as well.

> req.add_handler/req.handler and PythonInterpPerDirective

> MODPYTHON-125 made req.handler writable. Being able to now do this has unc
overed a bug whereby if PythonInterpPerDirective is used mod_python can caus
e Apache to crash. Code to trigger the problem is:
> # .htaccess
> SetHandler mod_python
> PythonInterpPerDirective On
> PythonFixupHandler interpreter_1
> # interpreter_1.py
> from mod_python import apache
> def fixuphandler(req):
>     req.log_error("fixuphandler")
>     req.log_error("interpreter=%s"%req.interpreter)
>     req.log_error("directory=%s"%req.hlist.directory)
>     req.handler = "mod_python"
>     req.add_handler("PythonHandler","interpreter_1")
>     return apache.OK
> def handler(req):
>     req.log_error("handler")
>     req.log_error("interpreter=%s"%req.interpreter)
>     req.log_error("directory=%s"%req.hlist.directory)
>     req.content_type = 'text/plain'
>     req.write('hello')
>     return apache.OK
> In summary, if PythonHandler is not used in Apache configuration to enable mod_pyt
hon but it is done by assignment to req.handler in fixup phase and then req.add_hand
ler() is used to add a handler to be called for content phase, and PythonInterpPerDi
rec
tive is being used, mod_python will cause Apache to crash.
> Location of crash not yet identified.
