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) move-faqwiz.sh Script to move faqwiz entries. 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). --Guido van Rossum (home page: http://www.python.org/~guido/)
