- * Functions declared include:
- *
+ *
+ * Functions declared include: cgi_edit_*
+ *
+ * NOTE: The CGIs in this file use parameter names
+ * such as "f" and "s" which are really *BAD* choices.
+ * However, I'm trying to save bytes in the
+ * edit-actions-list HTML page - the standard actions
+ * file generated a 550kbyte page, which is ridiculous.
+ *
+ * Stick to the short names in this file for consistency.

* Revisions :
- * $Log: cgi.c,v $
+ * $Log: cgiedit.c,v $
+ * Revision 1.13 2002/03/04 02:07:59 david__schmidt
+ * Enable web editing of actions file on OS/2 (it had been broken all this time!)
+ *
+ * Revision 1.12 2002/03/03 09:18:03 joergs
+ * Made jumbjuster work on AmigaOS again.
+ *
+ * Revision 1.11 2002/01/23 01:03:31 jongfoster
+ * Fixing gcc [CygWin] compiler warnings
+ *
+ * Revision 1.10 2002/01/23 00:22:59 jongfoster
+ * Adding new function cgi_edit_actions_section_swap(), to reorder
+ * the actions file.
+ *
+ * Adding get_url_spec_param() to get a validated URL pattern.
+ *
+ * Moving edit_read_line() out of this file and into loaders.c.
+ *
+ * Adding missing html_encode() to many CGI functions.
+ *
+ * Moving the functions that #include actionlist.h to the end of the file,
+ * because the Visual C++ 97 debugger gets extremely confused if you try
+ * to debug any code that comes after them in the file.
+ *
+ * Major optimizations in cgi_edit_actions_list() to reduce the size of
+ * the generated HTML (down 40% from 550k to 304k), with major side-effects
+ * throughout the editor and templates. In particular, the length of the
+ * URLs throughout the editor has been drastically reduced, by cutting
+ * paramater names down to 1 character and CGI names down to 3-4
+ * characters, by removing all non-essential CGI paramaters even at the
+ * expense of having to re-read the actions file for the most trivial
+ * page, and by using relative rather than absolute URLs. This means
+ * that this (typical example):
+ *
+ * <a href="http://ijbswa.sourceforge.net/config/edit-actions-url-form?
+ * filename=ijb&ver=1011487572&section=12&pattern=13
+ * &oldval=www.oesterhelt.org%2Fdeanimate-demo">
+ *
+ * is now this:
+ *
+ * <a href="eau?f=ijb&v=1011487572&p=13">
+ *
+ * Revision 1.9 2002/01/17 20:56:22 jongfoster
+ * Replacing hard references to the URL of the config interface
+ * with #defines from project.h
+ *
+ * Revision 1.8 2001/11/30 23:35:51 jongfoster
+ * Renaming actionsfile to ijb.action
+ *
+ * Revision 1.7 2001/11/13 00:28:24 jongfoster
+ * - Renaming parameters from edit-actions-for-url so that they only
+ * contain legal JavaScript characters. If we wanted to write
+ * JavaScript that worked with Netscape 4, this is nessacery.
+ * (Note that at the moment the JavaScript doesn't actually work
+ * with Netscape 4, but now this is purely a template issue, not
+ * one affecting code).
+ * - Adding new CGIs for use by non-JavaScript browsers:
+ * edit-actions-url-form
+ * edit-actions-add-url-form
+ * edit-actions-remove-url-form
+ * - Fixing || bug.
+ *
+ * Revision 1.6 2001/10/29 03:48:09 david__schmidt
+ * OS/2 native needed a snprintf() routine. Added one to miscutil, brackedted
+ * by and __OS2__ ifdef.
+ *
+ * Revision 1.5 2001/10/25 03:40:48 david__schmidt
+ * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
+ * threads to call select() simultaneously. So, it's time to do a real, live,
+ * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
+ * (native). Both versions will work, but using __OS2__ offers multi-threading.
+ *
+ * Revision 1.4 2001/10/23 21:48:19 jongfoster
+ * Cleaning up error handling in CGI functions - they now send back
+ * a HTML error page and should never cause a FATAL error. (Fixes one
+ * potential source of "denial of service" attacks).
+ *
+ * CGI actions file editor that works and is actually useful.
+ *
+ * Ability to toggle JunkBuster remotely using a CGI call.
+ *
+ * You can turn off both the above features in the main configuration
+ * file, e.g. if you are running a multi-user proxy.
+ *
+ * Revision 1.3 2001/10/14 22:12:49 jongfoster
+ * New version of CGI-based actionsfile editor.
+ * Major changes, including:
+ * - Completely new file parser and file output routines
+ * - edit-actions CGI renamed edit-actions-for-url
+ * - All CGIs now need a filename parameter, except for...
+ * - New CGI edit-actions which doesn't need a filename,
+ * to allow you to start the editor up.
+ * - edit-actions-submit now works, and now automatically
+ * redirects you back to the main edit-actions-list handler.
+ *
+ * Revision 1.2 2001/09/16 17:05:14 jongfoster
+ * Removing unused #include showarg.h
+ *
+ * Revision 1.1 2001/09/16 15:47:37 jongfoster
+ * First version of CGI-based edit interface. This is very much a
+ * work-in-progress, and you can't actually use it to edit anything
+ * yet. You must #define FEATURE_CGI_EDIT_ACTIONS for these changes
+ * to have any effect.

+ * Function : javascriptify
+ *
+ * Description : Converts a string into a form JavaScript will like.
+ *
+ * Netscape 4's JavaScript sucks - it doesn't use
+ * "id" parameters, so you have to set the "name"
+ * used to submit a form element to something JavaScript
+ * will like. (Or access the elements by index in an
+ * array. That array contains >60 elements and will
+ * be changed whenever we add a new action to the
+ * editor, so I'm NOT going to use indexes that have
+ * to be figured out by hand.)
+ *
+ * Currently the only thing we have to worry about
+ * is "-" ==> "_" conversion.
+ *
+ * This is a length-preserving operation so it is
+ * carried out in-place, no memory is allocated
+ * or freed.
+ *
+ * Parameters :
+ * 1 : identifier = String to make JavaScript-friendly.
+ *
+ * Returns : N/A
+ *
