- FAQ Wizard
- ----------
-
- Author: Guido van Rossum <guido@python.org>
- Version: 1.0
- Date: 6 April 1998
-
-
- This is a CGI program that maintains a user-editable FAQ. It uses RCS
- to keep track of changes to individual FAQ entries. It is fully
- configurable; everything you might want to change when using this
- program to maintain some other FAQ than the Python FAQ is contained in
- the configuration module, faqconf.py.
-
- Note that the bulk of the code is not an executable script; it's an
- importable module. The actual script in cgi-bin is minimal.
-
- Files:
-
- faqw.py executable script to be edited and installed in cgi-bin
- faqwiz.py main module, lives in same directory as FAQ entry files
- faqconf.py main configuration module
- faqcust.py additional local customization module (optional)
-
-
- What's New?
- -----------
-
- Version 1.0 corrects some minor bugs and uses tab-agnostic
- indentation; it is otherwise unchanged from version 0.9.0.
-
- Version 0.9.0 uses the re module (Perl style regular expressions) for
- all its regular expression needs, instead of the regex and regsub
- modules (Emacs style). This affects the syntax for regular
- expressions entered by the user as search strings (with "regular
- expression" checked), hence the version number jump.
-
-
- Setup Information
- -----------------
-
- This assumes you are familiar with Python, with your http server, and
- with running CGI scripts under your http server. You need Python 1.5
- or better.
-
- Select a place where the Python modules that constitute the FAQ wizard
- will live (the directory where you unpacked it is an obvious choice).
- This will be called the SRCDIR. This directory should not be writable
- by other users of your system (since they would be able to execute
- arbitrary code by invoking the FAQ wizard's CGI script).
-
- Create a dedicated working directory, preferably one that's not
- directly reachable from your http server. This will be called the
- FAQDIR. Create a subdirectory named RCS. Make both the working
- directory and the RCS subdirectory wrld-writable. (This is essential,
- since the FAQ wizard runs as use nobody, and needs to create
- additional files here!)
-
- Edit faqconf.py to reflect your setup. You only need to edit the top
- part, up till the line of all dashes. The comments should guide you
- in your edits. (Actually, you can also choose to add your changes to
- faqcust.py and leave faqconf.py alone. This is essential if you are
- maintaining multiple FAQs; see below.)
-
- Don't forget to edit the SECTION_TITLES variables to reflect the set
- of section titles for your FAQ!
-
- Next, edit faqw.py to reflect the pathname of your Python interpreter
- and the values for SRCDIR and FAQDIR that you just chose. Then
- install faqw.py in your cgi-bin directory. Make sure that it is
- world-executable. You should now be able to connect to the FAQ wizard
- by entering the following URL in your web client (subsituting the
- appropriate host and port for "your.web.server", and perhaps
- specifying a different directory for "cgi-bin" if local conventions so
- dictate):
-
- http://your.web.server/cgi-bin/faqw.py
-
- If you are unable to get this working, check your server's error_log
- file. The documentation for Python's cgi module in the Python Library
- Reference Manual gives plentyu additional information about installing
- and debugging CGI scripts, including setup debugging. This
- documentation is repeated in the doc string in the cgi module; try
- ``import cgi; print cgi.__doc__''.
-
- Assuming this works, you should now be able to add the first entry to
- your FAQ using the FAQ wizard interface. This creates a file
- faq01.001.htp in your working directory and an RCS revision history
- file faq01.001.htp,v in the RCS subdirectory. You can now exercise
- the other FAQ wizard features (search, index, whole FAQ, what's new,
- roulette, and so on).
-
-
- Maintaining Multiple FAQs
- -------------------------
-
- If you have multiple FAQs, you need a separate FAQDIR per FAQ, and a
- different customization file per FAQ. The easiest thing to do would
- be to have the faqcust.py for each FAQ live in the FAQDIR for that
- FAQ, but that creates some security concerns, since the FAQDIR must be
- world writable: *if* someone who breaks into your system (or a
- legitimate user) manages to edit the faqcust.py file they can get
- arbitrary code to execute through the FAQ wizard. Therefore, you will
- need a more complex setup.
-
- The best way is probably to have a directory that is only writable by
- you for each FAQ, where you place the copy of faqcust.py for that FAQ,
- and have a world-writable subdirectory DATA for the data. You then
- set FAQDIR to point to the DATA directory and change the faqw.py
- bootstrap script to add FAQDIR/.. to sys.path (in front of SRCDIR, so
- the dummy faqcust.py from SRCDIR is ignored).
