Graham Dumpleton commented on MODPYTHON-37:
-------------------------------------------

Note, attached diff has minor mistake. See following excerpt from mailing
list note this as well as a bit of documentation.

> I need to know what all parameters apache.register_cleanup() is expecting.

Just like you had called req.register_cleanup() except that cleanup
handler is called on server shutdown like req.server.register_cleanup().

 register_cleanup(callable[, data])

   Registers a cleanup. Argument callable can be any callable object, the
   optional argument data can be any object (default is  None). At Apache
   child process termination, callable will be called with one argument, data.

   If errors are encountered during cleanup processing, they should be in
   error log.

Note that I have actually made a minor mistake in the code. In apache.py,
the prototype should be:

  def register_cleanup(handler,data=None):
      _apache.register_cleanup(_interpreter,_server,handler,data)

I used "args=()" which isn't technically correct but only in as much as
I used "()" instead of "None". I was thinking you could supply a tuple of
arguments whereas you can actually only supply a single argument. What I
did wouldn't have stopped it working though.

Anyway, you should be able to do:

  def shutdown1():
      apache.log_error("shutdown1")

  apache.register_cleanup(shutdown1)

  def shutdown2(data):
      apache.log_error("shutdown2 %r"%data)

  apache.register_cleanup(shutdown2,"data")
