- *
- * Revision 1.31 2002/05/06 07:56:50 oes
- * Made actions_to_html independent of FEATURE_CGI_EDIT_ACTIONS
- *
- * Revision 1.30 2002/04/30 11:14:52 oes
- * Made csp the first parameter in *action_to_html
- *
- * Revision 1.29 2002/04/26 19:30:54 jongfoster
- * - current_action_to_html(): Adding help link for the "-" form of
- * one-string actions.
- * - Some actions had "<br>-", some "<br> -" (note the space).
- * Standardizing on no space.
- * - Greatly simplifying some of the code by using string_join()
- * where appropriate.
- *
- * Revision 1.28 2002/04/26 12:53:15 oes
- * - CGI AF editor now writes action lines split into
- * single lines with line continuation
- * - actions_to_html now embeds each action name in
- * link to chapter
- * - current_action_to_text is now called current_action_to_html
- * and acts like actions_to_html
- *
- * Revision 1.27 2002/04/24 02:10:31 oes
- * - Jon's patch for multiple AFs:
- * - split load_actions_file, add load_one_actions_file
- * - make csp->actions_list files an array
- * - remember file id with each action
- * - Copy_action now frees dest action before copying
- *
- * Revision 1.26 2002/03/26 22:29:54 swa
- * we have a new homepage!
- *
- * Revision 1.25 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.24 2002/03/16 23:54:06 jongfoster
- * Adding graceful termination feature, to help look for memory leaks.
- * If you enable this (which, by design, has to be done by hand
- * editing config.h) and then go to http://i.j.b/die, then the program
- * will exit cleanly after the *next* request. It should free all the
- * memory that was used.
- *
- * Revision 1.23 2002/03/07 03:46:16 oes
- * Fixed compiler warnings
- *
- * Revision 1.22 2002/01/21 00:27:02 jongfoster
- * Allowing free_action(NULL).
- * 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.
- *
- * Revision 1.21 2002/01/17 20:54:44 jongfoster
- * Renaming free_url to free_url_spec, since it frees a struct url_spec.
- *
- * Revision 1.20 2001/11/22 21:56:49 jongfoster
- * Making action_spec->flags into an unsigned long rather than just an
- * unsigned int.
- * Fixing a bug in the display of -add-header and -wafer
- *
- * Revision 1.19 2001/11/13 00:14:07 jongfoster
- * Fixing stupid bug now I've figured out what || means.
- * (It always returns 0 or 1, not one of it's paramaters.)
- *
- * Revision 1.18 2001/11/07 00:06:06 steudten
- * Add line number in error output for lineparsing for
- * actionsfile.
- *
- * Revision 1.17 2001/10/25 03:40:47 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 1.16 2001/10/23 21:30:30 jongfoster
- * Adding error-checking to selected functions.
- *
- * Revision 1.15 2001/10/14 21:58:22 jongfoster
- * Adding support for the CGI-based editor:
- * - Exported get_actions()
- * - Added new function free_alias_list()
- * - Added support for {{settings}} and {{description}} blocks
- * in the actions file. They are currently ignored.
- * - Added restriction to only one {{alias}} block which must appear
- * first in the file, to simplify the editor's rewriting rules.
- * - Note that load_actions_file() is no longer used by the CGI-based
- * editor, but some of the other routines in this file are.
- *
- * Revision 1.14 2001/09/22 16:36:59 jongfoster
- * Removing unused parameter fs from read_config_line()
- *
- * Revision 1.13 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.
- *
- * Revision 1.12 2001/09/16 13:21:27 jongfoster
- * Changes to use new list functions.
- *
- * Revision 1.11 2001/09/14 00:17:32 jongfoster
- * Tidying up memory allocation. New function init_action().
- *
- * Revision 1.10 2001/09/10 10:14:34 oes
- * Removing unused variable
- *
- * Revision 1.9 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:
- * - All feature #defines are now of the form FEATURE_xxx
- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.8 2001/06/29 13:19:52 oes
- * Removed logentry from cancelled commit
- *
- * Revision 1.7 2001/06/09 10:55:28 jongfoster
- * Changing BUFSIZ ==> BUFFER_SIZE
- *
- * Revision 1.6 2001/06/07 23:04:34 jongfoster
- * Made get_actions() static.
- *
- * Revision 1.5 2001/06/03 19:11:48 oes
- * adapted to new enlist_unique arg format
- *
- * Revision 1.4 2001/06/01 20:03:42 jongfoster
- * Better memory management - current_action->strings[] now
- * contains copies of the strings, not the original.
- *
- * Revision 1.3 2001/06/01 18:49:17 jongfoster
- * Replaced "list_share" with "list" - the tiny memory gain was not
- * worth the extra complexity.
- *
- * Revision 1.2 2001/05/31 21:40:00 jongfoster
- * Removing some commented out, obsolete blocks of code.
- *
- * Revision 1.1 2001/05/31 21:16:46 jongfoster
- * Moved functions to process the action list into this new file.

- *
- * Revision 1.9 2002/03/26 22:29:54 swa
- * we have a new homepage!
- *
- * Revision 1.8 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.7 2002/03/16 23:54:06 jongfoster
- * Adding graceful termination feature, to help look for memory leaks.
- * If you enable this (which, by design, has to be done by hand
- * editing config.h) and then go to http://i.j.b/die, then the program
- * will exit cleanly after the *next* request. It should free all the
- * memory that was used.
- *
- * Revision 1.6 2001/10/23 21:30:30 jongfoster
- * Adding error-checking to selected functions.
- *
- * Revision 1.5 2001/10/14 21:58:22 jongfoster
- * Adding support for the CGI-based editor:
- * - Exported get_actions()
- * - Added new function free_alias_list()
- * - Added support for {{settings}} and {{description}} blocks
- * in the actions file. They are currently ignored.
- * - Added restriction to only one {{alias}} block which must appear
- * first in the file, to simplify the editor's rewriting rules.
- * - Note that load_actions_file() is no longer used by the CGI-based
- * editor, but some of the other routines in this file are.
- *
- * Revision 1.4 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.
- *
- * Revision 1.3 2001/09/14 00:17:32 jongfoster
- * Tidying up memory allocation. New function init_action().
- *
- * Revision 1.2 2001/07/29 19:01:11 jongfoster
- * Changed _FILENAME_H to FILENAME_H_INCLUDED.
- * Added forward declarations for needed structures.
- *
- * Revision 1.1 2001/05/31 21:16:46 jongfoster

- * Name in version string changed from junkbuster to Privoxy.
- *
- * Revision 1.7 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.6 2002/03/09 20:03:52 jongfoster
- * - Making various functions return int rather than size_t.
- * (Undoing a recent change). Since size_t is unsigned on
- * Windows, functions like read_socket that return -1 on
- * error cannot return a size_t.
- *
- * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
- * crashes, and also frequently caused JB to jump to 100%
- * CPU and stay there. (Because it thought it had just
- * read ((unsigned)-1) == 4Gb of data...)
- *
- * - The signature of write_socket has changed, it now simply
- * returns success=0/failure=nonzero.
- *
- * - Trying to get rid of a few warnings --with-debug on
- * Windows, I've introduced a new type "jb_socket". This is
- * used for the socket file descriptors. On Windows, this
- * is SOCKET (a typedef for unsigned). Everywhere else, it's
- * an int. The error value can't be -1 any more, so it's
- * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
- * Windows it maps to the #define INVALID_SOCKET.)
- *
- * - The signature of bind_port has changed.
- *
- * Revision 1.5 2002/03/03 09:18:03 joergs
- * Made jumbjuster work on AmigaOS again.
- *
- * Revision 1.4 2001/10/07 15:35:13 oes
- * Replaced 6 boolean members of csp with one bitmap (csp->flags)
- *
- * Revision 1.3 2001/09/12 22:54:51 joergs
- * Stacksize of main thread increased.
- *
- * Revision 1.2 2001/05/23 00:13:58 joergs
- * AmigaOS support fixed.
- *

- *
- * Revision 1.45 2002/03/06 22:54:35 jongfoster
- * Automated function-comment nitpicking.
- *

- * - Fixing || bug.
- *
- * Revision 1.37 2001/11/01 14:28:47 david__schmidt
- * Show enablement/disablement status in almost all templates.
- * There is a little trickiness here: apparent recursive resolution of
- * @if-enabled-then@ caused the toggle template to show status out-of-phase with
- * the actual enablement status. So a similar construct,
- * @if-enabled-display-then@, is used to resolve the status display on non-'toggle'
- * templates.
- *
- * Revision 1.36 2001/10/26 17:33:27 oes
- * marginal bugfix
- *
- * Revision 1.35 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 1.34 2001/10/18 22:22:09 david__schmidt
- * Only show "Local support" on templates conditionally:
- * - if either 'admin-address' or 'proxy-info-url' are uncommented in config
- * - if not, no Local support section appears
- *
- * Revision 1.33 2001/10/14 22:28:41 jongfoster
- * Fixing stupid typo.
- *
- * Revision 1.32 2001/10/14 22:20:18 jongfoster
- * - Changes to CGI dispatching method to match CGI names exactly,
- * rather than doing a prefix match.
- * - No longer need to count the length of the CGI handler names by hand.
- * - Adding new handler for 404 error when disptching a CGI, if none of
- * the handlers match.
- * - Adding new handlers for CGI actionsfile editor.
- *
- * Revision 1.31 2001/10/10 10:56:39 oes
- * Failiure to load template now fatal. Before, the user got a hard-to-understand assertion failure from cgi.c
- *
- * Revision 1.30 2001/10/02 15:30:57 oes
- * Introduced show-request cgi
- *
- * Revision 1.29 2001/09/20 15:47:44 steudten
- *
- * Fix BUG: Modify int size to size_t size in fill_template()
- * - removes big trouble on machines where sizeof(int) != sizeof(size_t).
- *
- * Revision 1.28 2001/09/19 18:00:37 oes
- * - Deletef time() FIXME (Can't fail under Linux either, if
- * the argument is guaranteed to be in out address space,
- * which it is.)
- * - Fixed comments
- * - Pointer notation cosmetics
- * - Fixed a minor bug in template_fill(): Failiure of
- * pcrs_execute() now secure.
- *
- * Revision 1.27 2001/09/16 17:08:54 jongfoster
- * Moving simple CGI functions from cgi.c to new file cgisimple.c
- *
- * Revision 1.26 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.
- *
- * Revision 1.25 2001/09/16 15:02:35 jongfoster
- * Adding i.j.b/robots.txt.
- * Inlining add_stats() since it's only ever called from one place.
- *
- * Revision 1.24 2001/09/16 11:38:01 jongfoster
- * Splitting fill_template() into 2 functions:
- * template_load() loads the file
- * template_fill() performs the PCRS regexps.
- * This is because the CGI edit interface has a "table row"
- * template which is used many times in the page - this
- * change means it's only loaded from disk once.
- *
- * Revision 1.23 2001/09/16 11:16:05 jongfoster
- * Better error handling in dispatch_cgi() and parse_cgi_parameters()
- *

- * New function alloc_http_response, for symmetry with free_http_response
- *
- * Revision 1.21 2001/09/13 23:53:03 jongfoster
- * Support for both static and dynamically generated CGI pages.
- * Correctly setting Last-Modified: and Expires: HTTP headers.
- *
- * Revision 1.20 2001/09/13 23:40:36 jongfoster
- * (Cosmetic only) Indentation correction
- *
- * Revision 1.19 2001/09/13 23:31:25 jongfoster
- * Moving image data to cgi.c rather than cgi.h.
- *
- * Revision 1.18 2001/08/05 16:06:20 jongfoster
- * Modifiying "struct map" so that there are now separate header and
- * "map_entry" structures. This means that functions which modify a
- * map no longer need to return a pointer to the modified map.
- * Also, it no longer reverses the order of the entries (which may be
- * important with some advanced template substitutions).
- *
- * Revision 1.17 2001/08/05 15:57:38 oes
- * Adapted finish_http_response to new list_to_text
- *
- * Revision 1.16 2001/08/01 21:33:18 jongfoster
- * Changes to fill_template() that reduce memory usage without having
- * an impact on performance. I also renamed some variables so as not
- * to clash with the C++ keywords "new" and "template".
- *
- * Revision 1.15 2001/08/01 21:19:22 jongfoster
- * Moving file version information to a separate CGI page.
- *
- * Revision 1.14 2001/08/01 00:19:03 jongfoster
- * New function: map_conditional() for an if-then-else syntax.
- * Changing to use new version of show_defines()
- *
- * Revision 1.13 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:
- * - All feature #defines are now of the form FEATURE_xxx
- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.12 2001/07/29 18:47:05 jongfoster
- * Adding missing #include "loadcfg.h"
- *
- * Revision 1.11 2001/07/18 17:24:37 oes
- * Changed to conform to new pcrs interface
- *
- * Revision 1.10 2001/07/13 13:53:13 oes
- * Removed all #ifdef PCRS and related code
- *
- * Revision 1.9 2001/06/29 21:45:41 oes
- * Indentation, CRLF->LF, Tab-> Space
- *
- * Revision 1.8 2001/06/29 13:21:46 oes
- * - Cosmetics: renamed and reordered functions, variables,
- * texts, improved comments etc
- *
- * - Removed ij_untrusted_url() The relevant
- * info is now part of the "untrusted" page,
- * which is generated by filters.c:trust_url()
- *
- * - Generators of content now call finish_http_response()
- * themselves, making jcc.c:chat() a little less
- * cluttered
- *
- * - Removed obsolete "Pragma: no-cache" from our headers
- *
- * - http_responses now know their head length
- *
- * - fill_template now uses the new interface to pcrs, so that
- * - long jobs (like whole files) no longer have to be assembled
- * in a fixed size buffer
- * - the new T (trivial) option is used, and the replacement may
- * contain Perl syntax backrefs without confusing pcrs
- *
- * - Introduced default_exports() which generates a set of exports
- * common to all CGIs and other content generators
- *
- * - Introduced convenience function map_block_killer()
- *
- * - Introduced convenience function make_menu()
- *
- * - Introduced CGI-like function error_response() which generates
- * the "No such domain" and "Connect failed" messages using the
- * CGI platform
- *
- * - cgi_show_url_info:
- * - adapted to new CGI features
- * - form and answers now generated from same template
- * - http:// prefix in URL now OK
- *
- * - cgi_show_status:
- * - adapted to new CGI features
- * - no longer uses csp->init_proxy_args

- *
- * Revision 1.4 2001/06/04 10:41:52 swa

- * Function : cgi_error_unknown

- * Description : Almost-CGI function that is called if an unexpected

- * In this context, "unexpected" means "anything other

- * expected to handle all other errors internally,
- * since they can give more relavent error messages
- * that way.
- *
- * Note this is not a true CGI, it takes an error
- * code rather than a map of parameters.
- *
- * Parameters :
- * 1 : csp = Current client state (buffers, headers, etc...)
- * 2 : rsp = http_response data structure for output
- * 3 : error_to_report = Error code to report.
- *
- * Returns : JB_ERR_OK on success

- * Revision 1.20 2002/03/04 17:53:22 oes
- * Fixed compiled warning
- *
- * Revision 1.19 2002/01/21 00:33:52 jongfoster
- * Adding map_block_keep() to save a few bytes in the edit-actions-list HTML.

- * Revision 1.18 2001/11/16 00:46:31 jongfoster
- * Fixing compiler warnings
- *
- * Revision 1.17 2001/10/23 21:48:19 jongfoster
- * Cleaning up error handling in CGI functions - they now send back

- * CGI actions file editor that works and is actually useful.

- * You can turn off both the above features in the main configuration

- *
- * Revision 1.15 2001/09/16 15:02:35 jongfoster

- * Inlining add_stats() since it's only ever called from one place.
- *
- * Revision 1.14 2001/09/16 11:38:02 jongfoster
- * Splitting fill_template() into 2 functions:
- * template_load() loads the file
- * template_fill() performs the PCRS regexps.
- * This is because the CGI edit interface has a "table row"
- * template which is used many times in the page - this
- * change means it's only loaded from disk once.

- * Revision 1.11 2001/08/05 16:06:20 jongfoster
- * Modifiying "struct map" so that there are now separate header and
- * "map_entry" structures. This means that functions which modify a
- * map no longer need to return a pointer to the modified map.
- * Also, it no longer reverses the order of the entries (which may be
- * important with some advanced template substitutions).
- *
- * Revision 1.10 2001/08/01 21:19:22 jongfoster
- * Moving file version information to a separate CGI page.
- *
- * Revision 1.9 2001/08/01 00:17:54 jongfoster

- * ANSI C rules.
- *
- * Revision 1.6 2001/06/29 21:45:41 oes
- * Indentation, CRLF->LF, Tab-> Space
- *
- * Revision 1.5 2001/06/29 13:22:44 oes
- * - Cleaned up
- * - Added new functions: default_exports(), make_menu(),
- * error_response() etc, ranamed others and changed
- * param and return types.

- * 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

- * New version of CGI-based actionsfile editor.
- * Major changes, including:

- * - 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,

- * Revision 1.1 2001/09/16 15:47:37 jongfoster

- * Adding graceful termination feature, to help look for memory leaks.
- * If you enable this (which, by design, has to be done by hand

- * Adding cgi_transparent_gif() for http://i.j.b/t

- * Revision 1.4 2001/10/23 21:48:19 jongfoster
- * Cleaning up error handling in CGI functions - they now send back

- *
- * CGI actions file editor that works and is actually useful.

- * Revision 1.3 2001/10/14 22:00:32 jongfoster
- * Adding support for a 404 error when an invalid CGI page is requested.

- *
- * Revision 1.5 2001/05/22 18:46:04 oes
- *
- * - Enabled filtering banners by size rather than URL
- * by adding patterns that replace all standard banner
- * sizes with the "Junkbuster" gif to the re_filterfile
- *
- * - Enabled filtering WebBugs by providing a pattern
- * which kills all 1x1 images
- *
- * - Added support for PCRE_UNGREEDY behaviour to pcrs,
- * which is selected by the (nonstandard and therefore
- * capital) letter 'U' in the option string.
- * It causes the quantifiers to be ungreedy by default.
- * Appending a ? turns back to greedy (!).
- *
- * - Added a new interceptor ijb-send-banner, which
- * sends back the "Junkbuster" gif. Without imagelist or
- * MSIE detection support, or if tinygif = 1, or the
- * URL isn't recognized as an imageurl, a lame HTML
- * explanation is sent instead.
- *
- * - Added new feature, which permits blocking remote
- * script redirects and firing back a local redirect
- * to the browser.
- * The feature is conditionally compiled, i.e. it
- * can be disabled with --disable-fast-redirects,
- * plus it must be activated by a "fast-redirects"
- * line in the config file, has its own log level
- * and of course wants to be displayed by show-proxy-args
- * Note: Boy, all the #ifdefs in 1001 locations and
- * all the fumbling with configure.in and acconfig.h
- * were *way* more work than the feature itself :-(
- *
- * - Because a generic redirect template was needed for
- * this, tinygif = 3 now uses the same.
- *
- * - Moved GIFs, and other static HTTP response templates
- * to project.h
- *
- * - Some minor fixes
- *
- * - Removed some >400 CRs again (Jon, you really worked
- * a lot! ;-)
- *
- * Revision 1.4 2001/05/21 19:32:54 jongfoster
- * Added another #ifdef _WIN_CONSOLE
- *
- * Revision 1.3 2001/05/20 01:11:40 jongfoster
- * Added support for LOG_LEVEL_FATAL
- * Renamed LOG_LEVEL_FRC to LOG_LEVEL_FORCE,
- * and LOG_LEVEL_REF to LOG_LEVEL_RE_FILTER
- *
- * Revision 1.2 2001/05/17 22:42:01 oes
- * - Cleaned CRLF's from the sources and related files
- * - Repaired logging for REF and FRC
- *
- * Revision 1.1.1.1 2001/05/15 13:58:51 oes
- * Initial import of version 2.9.3 source tree
- *

- * Adding support for LOG_LEVEL_CGI

- * Revision 1.9 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:
- * - All feature #defines are now of the form FEATURE_xxx
- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS

- * Revision 1.7 2001/07/19 19:02:53 haroon
- * Added define for LOG_LEVEL_POPUPS
- *
- * Revision 1.6 2001/07/13 13:59:22 oes
- * - Added LOG_LEVEL_DEANIMATE
- * - Changed LOG_LEVEL_CLF
- * - Removed all #ifdef PCRS
- *
- * Revision 1.5 2001/05/26 17:25:14 jongfoster
- * Added support for CLF (Common Log Format) and fixed LOG_LEVEL_LOG
- *
- * Revision 1.4 2001/05/25 21:56:06 jongfoster
- * Added FIXME comment to (broken) LOG_LEVEL_LOG
- *
- * Revision 1.3 2001/05/22 18:46:04 oes
- *
- * - Enabled filtering banners by size rather than URL
- * by adding patterns that replace all standard banner
- * sizes with the "Junkbuster" gif to the re_filterfile
- *
- * - Enabled filtering WebBugs by providing a pattern
- * which kills all 1x1 images
- *
- * - Added support for PCRE_UNGREEDY behaviour to pcrs,
- * which is selected by the (nonstandard and therefore
- * capital) letter 'U' in the option string.
- * It causes the quantifiers to be ungreedy by default.
- * Appending a ? turns back to greedy (!).
- *
- * - Added a new interceptor ijb-send-banner, which
- * sends back the "Junkbuster" gif. Without imagelist or
- * MSIE detection support, or if tinygif = 1, or the
- * URL isn't recognized as an imageurl, a lame HTML
- * explanation is sent instead.
- *
- * - Added new feature, which permits blocking remote
- * script redirects and firing back a local redirect
- * to the browser.
- * The feature is conditionally compiled, i.e. it
- * can be disabled with --disable-fast-redirects,
- * plus it must be activated by a "fast-redirects"
- * line in the config file, has its own log level
- * and of course wants to be displayed by show-proxy-args
- * Note: Boy, all the #ifdefs in 1001 locations and
- * all the fumbling with configure.in and acconfig.h
- * were *way* more work than the feature itself :-(
- *
- * - Because a generic redirect template was needed for
- * this, tinygif = 3 now uses the same.
- *
- * - Moved GIFs, and other static HTTP response templates
- * to project.h
- *
- * - Some minor fixes
- *
- * - Removed some >400 CRs again (Jon, you really worked
- * a lot! ;-)
- *
- * Revision 1.2 2001/05/20 01:11:40 jongfoster
- * Added support for LOG_LEVEL_FATAL
- * Renamed LOG_LEVEL_FRC to LOG_LEVEL_FORCE,
- * and LOG_LEVEL_REF to LOG_LEVEL_RE_FILTER
- *
- * Revision 1.1.1.1 2001/05/15 13:58:51 oes
- * Initial import of version 2.9.3 source tree

- * Cosmetics
- *
- * Revision 1.48 2002/03/13 20:25:34 oes
- * Better logging for content filters
- *
- * Revision 1.47 2002/03/13 00:30:52 jongfoster
- * Killing warnings
- * Added option of always sending redirect for imageblock,
- * currently disabled with #if 0.
- *
- * Revision 1.46 2002/03/12 01:42:49 oes
- * Introduced modular filters
- *
- * Revision 1.45 2002/03/08 16:47:50 oes
- * Added choice beween GIF and PNG built-in images
- *
- * Revision 1.44 2002/03/07 03:49:31 oes
- * - Fixed compiler warnings etc
- * - Changed built-in images from GIF to PNG
- * (with regard to Unisys patent issue)
- * - Added a 4x4 pattern PNG which is less intrusive
- * than the logo but also clearly marks the deleted banners
- *
- * Revision 1.43 2002/01/22 23:51:59 jongfoster
- * Replacing strsav() with the safer string_append().
- *
- * Adding missing html_encode() to error message generators. Where encoded
- * and unencoded versions of a string were provided, removing the unencoded
- * one.
- *
- * Revision 1.42 2002/01/17 21:00:32 jongfoster
- * Moving all our URL and URL pattern parsing code to urlmatch.c.
- *
- * Using a single, simple url_match(pattern,url) function - rather than
- * the 3-line match routine which was repeated all over the place.
- *
- * Renaming free_url to free_url_spec, since it frees a struct url_spec.
- *
- * Using parse_http_url() to parse URLs without faking a HTTP
- * request line for parse_http_request().
- *
- * Revision 1.41 2001/11/13 00:14:07 jongfoster
- * Fixing stupid bug now I've figured out what || means.
- * (It always returns 0 or 1, not one of it's paramaters.)
- *
- * Revision 1.40 2001/10/26 17:37:55 oes
- * - Re-enabled Netscape 200/404 bug workaround in block_url():
- * - Removed OS/2 special case
- * - Made block_url() independant from sed() having been run
- * - Made trust_url independant from sed() having been run
- * - Made is_imageurl independant from sed() having been run.
- * It now checks User-Agent: and Accept: by itself.
- *
- *
- * Revision 1.39 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 1.38 2001/10/23 21:32:33 jongfoster
- * Adding error-checking to selected functions
- *
- * Revision 1.37 2001/10/22 15:33:56 david__schmidt
- * Special-cased OS/2 out of the Netscape-abort-on-404-in-js problem in
- * filters.c. Added a FIXME in front of the offending code. I'll gladly
- * put in a better/more robust fix for all parties if one is presented...
- * It seems that just returning 200 instead of 404 would pretty much fix
- * it for everyone, but I don't know all the history of the problem.
- *
- * Revision 1.36 2001/10/10 16:44:16 oes
- * Added match_portlist function
- *
- * Revision 1.35 2001/10/07 15:41:23 oes
- * Replaced 6 boolean members of csp with one bitmap (csp->flags)
- *
- * New function remove_chunked_transfer_coding that strips chunked
- * transfer coding to plain and is called by pcrs_filter_response
- * and gif_deanimate_response if neccessary
- *
- * Improved handling of zero-change re_filter runs
- *
- * pcrs_filter_response and gif_deanimate_response now remove
- * chunked transfer codeing before processing the body.
- *
- * Revision 1.34 2001/09/20 15:49:36 steudten
- *
- * Fix BUG: Change int size to size_t size in pcrs_filter_response().
- * See cgi.c fill_template().
- *
- * Revision 1.33 2001/09/16 17:05:14 jongfoster
- * Removing unused #include showarg.h
- *
- * Revision 1.32 2001/09/16 13:21:27 jongfoster
- * Changes to use new list functions.
- *
- * Revision 1.31 2001/09/16 11:38:02 jongfoster
- * Splitting fill_template() into 2 functions:
- * template_load() loads the file
- * template_fill() performs the PCRS regexps.
- * This is because the CGI edit interface has a "table row"
- * template which is used many times in the page - this
- * change means it's only loaded from disk once.
- *
- * Revision 1.30 2001/09/16 11:00:10 jongfoster
- * New function alloc_http_response, for symmetry with free_http_response
- *
- * Revision 1.29 2001/09/13 23:32:40 jongfoster
- * Moving image data to cgi.c rather than cgi.h
- * Fixing a GPF under Win32 (and any other OS that protects global
- * constants from being written to).
- *
- * Revision 1.28 2001/09/10 10:18:51 oes
- * Silenced compiler warnings
- *
- * Revision 1.27 2001/08/05 16:06:20 jongfoster
- * Modifiying "struct map" so that there are now separate header and
- * "map_entry" structures. This means that functions which modify a
- * map no longer need to return a pointer to the modified map.
- * Also, it no longer reverses the order of the entries (which may be
- * important with some advanced template substitutions).
- *
- * Revision 1.26 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:
- * - All feature #defines are now of the form FEATURE_xxx
- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.25 2001/07/26 10:09:46 oes
- * Made browser detection a little less naive
- *
- * Revision 1.24 2001/07/25 17:22:51 oes
- * Added workaround for Netscape bug that prevents display of page when loading a component fails.
- *
- * Revision 1.23 2001/07/23 13:40:12 oes
- * Fixed bug that caused document body to be dropped when pcrs joblist was empty.
- *
- * Revision 1.22 2001/07/18 12:29:34 oes
- * - Made gif_deanimate_response respect
- * csp->action->string[ACTION_STRING_DEANIMATE]
- * - Logging cosmetics
- *
- * Revision 1.21 2001/07/13 13:59:53 oes
- * - Introduced gif_deanimate_response which shares the
- * generic content modification interface of pcrs_filter_response
- * and acts as a wrapper to deanimate.c:gif_deanimate()
- * - Renamed re_process_buffer to pcrs_filter_response
- * - pcrs_filter_response now returns NULL on failiure
- * - Removed all #ifdef PCRS
- *
- * Revision 1.20 2001/07/01 17:01:04 oes
- * Added comments and missing return statement in is_untrusted_url()
- *
- * Revision 1.19 2001/06/29 21:45:41 oes
- * Indentation, CRLF->LF, Tab-> Space
- *
- * Revision 1.18 2001/06/29 13:27:38 oes
- * - Cleaned up, renamed and reorderd functions
- * and improved comments
- *
- * - block_url:
- * - Ported to CGI platform. Now delivers
- * http_response or NULL
- * - Unified HTML and GIF generation (moved image detection
- * and GIF generation here from jcc.c:chat())
- * - Fixed HTTP status to:
- * - 403 (Forbidden) for the "blocked" HTML message
- * - 200 (OK) for GIF answers
- * - 302 (Redirect) for redirect to GIF
- *
- * - trust_url:
- * - Ported to CGI platform. Now delivers
- * http_response or NULL
- * - Separated detection of untrusted URL into
- * (bool)is_untrusted_url
- * - Added enforcement of untrusted requests
- *
- * - Moved redirect_url() from cgi.c to here
- * and ported it to the CGI platform
- *
- * - Removed logentry from cancelled commit
- *
- * Revision 1.17 2001/06/09 10:55:28 jongfoster
- * Changing BUFSIZ ==> BUFFER_SIZE
- *
- * Revision 1.16 2001/06/07 23:10:26 jongfoster
- * Allowing unanchored domain patterns to back off and retry
- * if they partially match. Optimized right-anchored patterns.
- * Moving ACL and forward files into config file.
- * Replacing struct gateway with struct forward_spec
- *
- * Revision 1.15 2001/06/03 19:12:00 oes
- * extracted-CGI relevant stuff
- *
- * Revision 1.14 2001/06/01 10:30:55 oes
- * Added optional left-anchoring to domaincmp
- *
- * Revision 1.13 2001/05/31 21:21:30 jongfoster
- * Permissionsfile / actions file changes:
- * - Changed "permission" to "action" throughout
- * - changes to file format to allow string parameters
- * - Moved helper functions to actions.c
- *
- * Revision 1.12 2001/05/31 17:35:20 oes
- *
- * - Enhanced domain part globbing with infix and prefix asterisk
- * matching and optional unanchored operation
- *
- * Revision 1.11 2001/05/29 11:53:23 oes
- * "See why" link added to "blocked" page
- *
- * Revision 1.10 2001/05/29 09:50:24 jongfoster
- * Unified blocklist/imagelist/permissionslist.
- * File format is still under discussion, but the internal changes
- * are (mostly) done.
- *
- * Also modified interceptor behaviour:
- * - We now intercept all URLs beginning with one of the following
- * prefixes (and *only* these prefixes):
- * * http://i.j.b/
- * * http://ijbswa.sf.net/config/
- * * http://ijbswa.sourceforge.net/config/
- * - New interceptors "home page" - go to http://i.j.b/ to see it.
- * - Internal changes so that intercepted and fast redirect pages
- * are not replaced with an image.
- * - Interceptors now have the option to send a binary page direct
- * to the client. (i.e. ijb-send-banner uses this)
- * - Implemented show-url-info interceptor. (Which is why I needed
- * the above interceptors changes - a typical URL is
- * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
- * The previous mechanism would not have intercepted that, and
- * if it had been intercepted then it then it would have replaced
- * it with an image.)
- *
- * Revision 1.9 2001/05/27 22:17:04 oes
- *
- * - re_process_buffer no longer writes the modified buffer
- * to the client, which was very ugly. It now returns the
- * buffer, which it is then written by chat.
- *
- * - content_length now adjusts the Content-Length: header
- * for modified documents rather than crunch()ing it.
- * (Length info in csp->content_length, which is 0 for
- * unmodified documents)
- *
- * - For this to work, sed() is called twice when filtering.
- *
- * Revision 1.8 2001/05/26 17:13:28 jongfoster
- * Filled in a function comment.
- *
- * Revision 1.7 2001/05/26 15:26:15 jongfoster
- * ACL feature now provides more security by immediately dropping
- * connections from untrusted hosts.
- *
- * Revision 1.6 2001/05/26 00:28:36 jongfoster
- * Automatic reloading of config file.
- * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
- * Most of the global variables have been moved to a new
- * struct configuration_spec, accessed through csp->config->globalname
- * Most of the globals remaining are used by the Win32 GUI.
- *
- * Revision 1.5 2001/05/25 22:34:30 jongfoster
- * Hard tabs->Spaces
- *
- * Revision 1.4 2001/05/22 18:46:04 oes
- *
- * - Enabled filtering banners by size rather than URL
- * by adding patterns that replace all standard banner
- * sizes with the "Junkbuster" gif to the re_filterfile
- *
- * - Enabled filtering WebBugs by providing a pattern
- * which kills all 1x1 images
- *
- * - Added support for PCRE_UNGREEDY behaviour to pcrs,
- * which is selected by the (nonstandard and therefore
- * capital) letter 'U' in the option string.
- * It causes the quantifiers to be ungreedy by default.
- * Appending a ? turns back to greedy (!).
- *
- * - Added a new interceptor ijb-send-banner, which
- * sends back the "Junkbuster" gif. Without imagelist or
- * MSIE detection support, or if tinygif = 1, or the
- * URL isn't recognized as an imageurl, a lame HTML
- * explanation is sent instead.
- *
- * - Added new feature, which permits blocking remote
- * script redirects and firing back a local redirect
- * to the browser.
- * The feature is conditionally compiled, i.e. it
- * can be disabled with --disable-fast-redirects,
- * plus it must be activated by a "fast-redirects"
- * line in the config file, has its own log level
- * and of course wants to be displayed by show-proxy-args
- * Note: Boy, all the #ifdefs in 1001 locations and
- * all the fumbling with configure.in and acconfig.h
- * were *way* more work than the feature itself :-(
- *
- * - Because a generic redirect template was needed for
- * this, tinygif = 3 now uses the same.
- *
- * - Moved GIFs, and other static HTTP response templates
- * to project.h
- *
- * - Some minor fixes
- *
- * - Removed some >400 CRs again (Jon, you really worked
- * a lot! ;-)
- *
- * Revision 1.3 2001/05/20 16:44:47 jongfoster
- * Removing last hardcoded Junkbusters.com URLs.
- *
- * Revision 1.2 2001/05/20 01:21:20 jongfoster
- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.
- *
- * Revision 1.1.1.1 2001/05/15 13:58:52 oes
- * Initial import of version 2.9.3 source tree
- *

- * extracted-CGI relevant stuff
- *
- * Revision 1.7 2001/05/31 21:21:30 jongfoster
- * Permissionsfile / actions file changes:
- * - Changed "permission" to "action" throughout
- * - changes to file format to allow string parameters
- * - Moved helper functions to actions.c
- *
- * Revision 1.6 2001/05/29 09:50:24 jongfoster
- * Unified blocklist/imagelist/permissionslist.
- * File format is still under discussion, but the internal changes
- * are (mostly) done.
- *
- * Also modified interceptor behaviour:
- * - We now intercept all URLs beginning with one of the following
- * prefixes (and *only* these prefixes):
- * * http://i.j.b/
- * * http://ijbswa.sf.net/config/
- * * http://ijbswa.sourceforge.net/config/
- * - New interceptors "home page" - go to http://i.j.b/ to see it.
- * - Internal changes so that intercepted and fast redirect pages
- * are not replaced with an image.
- * - Interceptors now have the option to send a binary page direct
- * to the client. (i.e. ijb-send-banner uses this)
- * - Implemented show-url-info interceptor. (Which is why I needed
- * the above interceptors changes - a typical URL is
- * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
- * The previous mechanism would not have intercepted that, and
- * if it had been intercepted then it then it would have replaced
- * it with an image.)
- *
- * Revision 1.5 2001/05/27 22:17:04 oes
- *
- * - re_process_buffer no longer writes the modified buffer
- * to the client, which was very ugly. It now returns the
- * buffer, which it is then written by chat.
- *
- * - content_length now adjusts the Content-Length: header
- * for modified documents rather than crunch()ing it.
- * (Length info in csp->content_length, which is 0 for
- * unmodified documents)
- *
- * - For this to work, sed() is called twice when filtering.
- *
- * Revision 1.4 2001/05/26 15:26:15 jongfoster
- * ACL feature now provides more security by immediately dropping
- * connections from untrusted hosts.
- *
- * Revision 1.3 2001/05/22 18:46:04 oes
- *
- * - Enabled filtering banners by size rather than URL
- * by adding patterns that replace all standard banner
- * sizes with the "Junkbuster" gif to the re_filterfile
- *
- * - Enabled filtering WebBugs by providing a pattern
- * which kills all 1x1 images
- *
- * - Added support for PCRE_UNGREEDY behaviour to pcrs,
- * which is selected by the (nonstandard and therefore
- * capital) letter 'U' in the option string.
- * It causes the quantifiers to be ungreedy by default.
- * Appending a ? turns back to greedy (!).
- *
- * - Added a new interceptor ijb-send-banner, which
- * sends back the "Junkbuster" gif. Without imagelist or
- * MSIE detection support, or if tinygif = 1, or the
- * URL isn't recognized as an imageurl, a lame HTML
- * explanation is sent instead.
- *
- * - Added new feature, which permits blocking remote
- * script redirects and firing back a local redirect
- * to the browser.
- * The feature is conditionally compiled, i.e. it
- * can be disabled with --disable-fast-redirects,
- * plus it must be activated by a "fast-redirects"
- * line in the config file, has its own log level
- * and of course wants to be displayed by show-proxy-args
- * Note: Boy, all the #ifdefs in 1001 locations and
- * all the fumbling with configure.in and acconfig.h
- * were *way* more work than the feature itself :-(
- *
- * - Because a generic redirect template was needed for
- * this, tinygif = 3 now uses the same.
- *
- * - Moved GIFs, and other static HTTP response templates
- * to project.h
- *
- * - Some minor fixes
- *
- * - Removed some >400 CRs again (Jon, you really worked
- * a lot! ;-)
- *
- * Revision 1.2 2001/05/20 01:21:20 jongfoster
- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.
- *
- * Revision 1.1.1.1 2001/05/15 13:58:52 oes
- * Initial import of version 2.9.3 source tree
- *

- * Killing warnings
- *
- * Revision 1.12 2002/03/09 20:03:52 jongfoster
- * - Making various functions return int rather than size_t.
- * (Undoing a recent change). Since size_t is unsigned on
- * Windows, functions like read_socket that return -1 on
- * error cannot return a size_t.
- *
- * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
- * crashes, and also frequently caused JB to jump to 100%
- * CPU and stay there. (Because it thought it had just
- * read ((unsigned)-1) == 4Gb of data...)
- *
- * - The signature of write_socket has changed, it now simply
- * returns success=0/failure=nonzero.
- *
- * - Trying to get rid of a few warnings --with-debug on
- * Windows, I've introduced a new type "jb_socket". This is
- * used for the socket file descriptors. On Windows, this
- * is SOCKET (a typedef for unsigned). Everywhere else, it's
- * an int. The error value can't be -1 any more, so it's
- * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
- * Windows it maps to the #define INVALID_SOCKET.)
- *
- * - The signature of bind_port has changed.
- *
- * Revision 1.11 2002/03/08 17:46:04 jongfoster
- * Fixing int/size_t warnings
- *
- * Revision 1.10 2002/03/07 03:50:19 oes
- * - Improved handling of failed DNS lookups
- * - Fixed compiler warnings
- *
- * Revision 1.9 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.

- * Removing gateways[] list - no longer used.
- * Replacing function pointer in struct gateway with a directly
- * called function forwarded_connect(), which can do the common
- * task of deciding whether to connect to the web server or HTTP
- * proxy.
- * Replacing struct gateway with struct forward_spec
- * Fixing bug with SOCKS4A and HTTP proxy server in combination.
- * It was a bug which led to the connection being made to the web
- * server rather than the HTTP proxy, and also a buffer overrun.

- * Revision 1.5 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.4 2002/03/09 20:03:52 jongfoster
- * - Making various functions return int rather than size_t.
- * (Undoing a recent change). Since size_t is unsigned on
- * Windows, functions like read_socket that return -1 on
- * error cannot return a size_t.
- *
- * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
- * crashes, and also frequently caused JB to jump to 100%
- * CPU and stay there. (Because it thought it had just
- * read ((unsigned)-1) == 4Gb of data...)
- *
- * - The signature of write_socket has changed, it now simply
- * returns success=0/failure=nonzero.
- *
- * - Trying to get rid of a few warnings --with-debug on
- * Windows, I've introduced a new type "jb_socket". This is
- * used for the socket file descriptors. On Windows, this
- * is SOCKET (a typedef for unsigned). Everywhere else, it's
- * an int. The error value can't be -1 any more, so it's
- * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
- * Windows it maps to the #define INVALID_SOCKET.)
- *
- * - The signature of bind_port has changed.
- *
- * Revision 1.3 2001/07/29 18:58:15 jongfoster
- * Removing nested #includes, adding forward declarations for needed
- * structures, and changing the #define _FILENAME_H to FILENAME_H_INCLUDED.
- *
- * Revision 1.2 2001/06/07 23:12:14 jongfoster
- * Removing gateways[] list - no longer used.
- * Replacing function pointer in struct gateway with a directly
- * called function forwarded_connect(), which can do the common
- * task of deciding whether to connect to the web server or HTTP
- * proxy.
- * Replacing struct gateway with struct forward_spec
- *
- * Revision 1.1.1.1 2001/05/15 13:58:54 oes
- * Initial import of version 2.9.3 source tree

- * 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__

- * Moved downgrading of the HTTP version from parse_http_request to
- * chat(), since we can't decide if it is necessary before we have
- * determined the actions for the URL. The HTTP command is now
- * *always* re-built so the repairs need no longer be special-cased.
- *
- * filter_popups now gets a csp pointer so it can raise the new
- * CSP_FLAG_MODIFIED flag.
- *
- * Bugfix
- *
- * Added configurable size limit for the IOB. If the IOB grows so
- * large that the next read would exceed the limit, the header
- * is generated, and the header & unfiltered buffer are flushed
- * to the client. Chat then continues in non-buffering,

- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.33 2001/07/29 19:32:00 jongfoster
- * Renaming _main() [mingw32 only] to real_main(), for ANSI compliance.
- *
- * Revision 1.32 2001/07/29 18:47:05 jongfoster
- * Adding missing #include "loadcfg.h"
- *
- * Revision 1.31 2001/07/29 12:17:48 oes
- * Applied pthread fix by Paul Lieverse
- *
- * Revision 1.30 2001/07/25 22:57:13 jongfoster
- * __BEOS__ no longer overrides FEATURE_PTHREAD.
- * This is because FEATURE_PTHREAD will soon be widely used, so I
- * want to keep it simple.
- *
- * Revision 1.29 2001/07/24 12:47:06 oes
- * Applied BeOS support update by Eugenia
- *
- * Revision 1.28 2001/07/23 13:26:12 oes
- * Fixed bug in popup-killing for the first read that caused binary garbage to be sent between headers and body
- *
- * Revision 1.27 2001/07/19 19:09:47 haroon
- * - Added code to take care of the situation where while processing the first
- * server response (which includes the server header), after finding the end
- * of the headers we were not looking past the end of the headers for
- * content modification. I enabled it for filter_popups.
- * Someone else should look to see if other similar operations should be
- * done to the discarded portion of the buffer.
- *
- * Note 2001/07/20: No, the other content modification mechanisms will process
- * the whole iob later anyway. --oes
- *
- * Revision 1.26 2001/07/18 12:31:36 oes
- * cosmetics
- *
- * Revision 1.25 2001/07/15 19:43:49 jongfoster
- * Supports POSIX threads.
- * Also removed some unused #includes.
- *
- * Revision 1.24 2001/07/13 14:00:40 oes
- * - Generic content modification scheme:
- * Each feature has its own applicability flag that is set
- * from csp->action->flags.
- * Replaced the "filtering" int flag , by a function pointer
- * "content_filter" to the function that will do the content
- * modification. If it is != NULL, the document will be buffered
- * and processed through *content_filter, which must set
- * csp->content_length and return a modified copy of the body
- * or return NULL (on failiure).
- * - Changed csp->is_text to the more generic bitmap csp->content_type
- * which can currently take the valued CT_TEXT or CT_GIF
- * - Reformatting etc
- * - Removed all #ifdef PCRS
- *
- * Revision 1.23 2001/07/02 02:28:25 iwanttokeepanon
- * Added "#ifdef ACL_FILES" conditional compilation to line 1291 to exclude
- * the `block_acl' call. This prevents a compilation error when the user
- * does not wish to use the "ACL" feature.
- *
- * Revision 1.22 2001/06/29 21:45:41 oes
- * Indentation, CRLF->LF, Tab-> Space
- *
- * Revision 1.21 2001/06/29 13:29:36 oes
- * - Cleaned up, improved comments
- * - Unified all possible interceptors (CGI,
- * block, trust, fast_redirect) in one
- * place, with one (CGI) answer generation
- * mechansim. Much clearer now.
- * - Removed the GIF image generation, which
- * is now done in filters.c:block_url()
- * - Made error conditions like domain lookup
- * failiure or (various) problems while talking
- * to the server use cgi.c:error_response()
- * instead of generating HTML/HTTP in chat() (yuck!)
- * - Removed logentry from cancelled commit
- *
- * Revision 1.20 2001/06/09 10:55:28 jongfoster
- * Changing BUFSIZ ==> BUFFER_SIZE
- *
- * Revision 1.19 2001/06/07 23:12:52 jongfoster
- * Replacing function pointer in struct gateway with a directly
- * called function forwarded_connect().
- * Replacing struct gateway with struct forward_spec
- *
- * Revision 1.18 2001/06/03 19:12:16 oes
- * introduced new cgi handling
- *
- * Revision 1.17 2001/06/01 20:07:23 jongfoster
- * Now uses action +image-blocker{} rather than config->tinygif
- *
- * Revision 1.16 2001/06/01 18:49:17 jongfoster
- * Replaced "list_share" with "list" - the tiny memory gain was not
- * worth the extra complexity.
- *
- * Revision 1.15 2001/05/31 21:24:47 jongfoster
- * Changed "permission" to "action" throughout.
- * Removed DEFAULT_USER_AGENT - it must now be specified manually.
- * Moved vanilla wafer check into chat(), since we must now
- * decide whether or not to add it based on the URL.
- *
- * Revision 1.14 2001/05/29 20:14:01 joergs
- * AmigaOS bugfix: PCRS needs a lot of stack, stacksize for child threads
- * increased.
- *
- * Revision 1.13 2001/05/29 09:50:24 jongfoster
- * Unified blocklist/imagelist/permissionslist.
- * File format is still under discussion, but the internal changes
- * are (mostly) done.
- *
- * Also modified interceptor behaviour:
- * - We now intercept all URLs beginning with one of the following
- * prefixes (and *only* these prefixes):
- * * http://i.j.b/
- * * http://ijbswa.sf.net/config/
- * * http://ijbswa.sourceforge.net/config/
- * - New interceptors "home page" - go to http://i.j.b/ to see it.
- * - Internal changes so that intercepted and fast redirect pages
- * are not replaced with an image.
- * - Interceptors now have the option to send a binary page direct
- * to the client. (i.e. ijb-send-banner uses this)
- * - Implemented show-url-info interceptor. (Which is why I needed
- * the above interceptors changes - a typical URL is
- * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
- * The previous mechanism would not have intercepted that, and
- * if it had been intercepted then it then it would have replaced
- * it with an image.)
- *
- * Revision 1.12 2001/05/27 22:17:04 oes
- *
- * - re_process_buffer no longer writes the modified buffer
- * to the client, which was very ugly. It now returns the
- * buffer, which it is then written by chat.
- *
- * - content_length now adjusts the Content-Length: header
- * for modified documents rather than crunch()ing it.
- * (Length info in csp->content_length, which is 0 for
- * unmodified documents)
- *
- * - For this to work, sed() is called twice when filtering.
- *
- * Revision 1.11 2001/05/26 17:27:53 jongfoster
- * Added support for CLF and fixed LOG_LEVEL_LOG.
- * Also did CRLF->LF fix of my previous patch.
- *
- * Revision 1.10 2001/05/26 15:26:15 jongfoster
- * ACL feature now provides more security by immediately dropping
- * connections from untrusted hosts.
- *
- * Revision 1.9 2001/05/26 00:28:36 jongfoster
- * Automatic reloading of config file.
- * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
- * Most of the global variables have been moved to a new
- * struct configuration_spec, accessed through csp->config->globalname
- * Most of the globals remaining are used by the Win32 GUI.
- *
- * Revision 1.8 2001/05/25 22:43:18 jongfoster
- * Fixing minor memory leak and buffer overflow.
- *
- * Revision 1.7 2001/05/25 22:34:30 jongfoster
- * Hard tabs->Spaces
- *
- * Revision 1.6 2001/05/23 00:13:58 joergs
- * AmigaOS support fixed.
- *
- * Revision 1.5 2001/05/22 18:46:04 oes
- *
- * - Enabled filtering banners by size rather than URL
- * by adding patterns that replace all standard banner
- * sizes with the "Junkbuster" gif to the re_filterfile
- *
- * - Enabled filtering WebBugs by providing a pattern
- * which kills all 1x1 images
- *
- * - Added support for PCRE_UNGREEDY behaviour to pcrs,
- * which is selected by the (nonstandard and therefore
- * capital) letter 'U' in the option string.
- * It causes the quantifiers to be ungreedy by default.
- * Appending a ? turns back to greedy (!).
- *
- * - Added a new interceptor ijb-send-banner, which
- * sends back the "Junkbuster" gif. Without imagelist or
- * MSIE detection support, or if tinygif = 1, or the
- * URL isn't recognized as an imageurl, a lame HTML
- * explanation is sent instead.
- *
- * - Added new feature, which permits blocking remote
- * script redirects and firing back a local redirect
- * to the browser.
- * The feature is conditionally compiled, i.e. it
- * can be disabled with --disable-fast-redirects,
- * plus it must be activated by a "fast-redirects"
- * line in the config file, has its own log level
- * and of course wants to be displayed by show-proxy-args
- * Note: Boy, all the #ifdefs in 1001 locations and
- * all the fumbling with configure.in and acconfig.h
- * were *way* more work than the feature itself :-(
- *
- * - Because a generic redirect template was needed for
- * this, tinygif = 3 now uses the same.
- *
- * - Moved GIFs, and other static HTTP response templates
- * to project.h
- *
- * - Some minor fixes
- *
- * - Removed some >400 CRs again (Jon, you really worked
- * a lot! ;-)
- *
- * Revision 1.4 2001/05/21 19:34:01 jongfoster
- * Made failure to bind() a fatal error.
- *
- * Revision 1.3 2001/05/20 01:21:20 jongfoster
- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.
- *
- * Revision 1.2 2001/05/17 22:34:44 oes
- * - Added hint on GIF char array generation to jcc.c
- * - Cleaned CRLF's from the sources and related files
- * - Repaired logging for REF and FRC
- *
- * Revision 1.1.1.1 2001/05/15 13:58:56 oes
- * Initial import of version 2.9.3 source tree
- *

- * Revision 1.12 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,

- * Revision 1.7 2001/08/05 16:06:20 jongfoster
- * Modifiying "struct map" so that there are now separate header and
- * "map_entry" structures. This means that functions which modify a
- * map no longer need to return a pointer to the modified map.
- * Also, it no longer reverses the order of the entries (which may be

- * Revision 1.4 2001/06/29 13:30:22 oes
- * - Added Convenience function enlist_unique_header(),
- * which takes the Header name and value as separate
- * arguments and thus saves the pain of sprintf()ing
- * and determining the Header name length to enlist_unique
- * - Improved comments
- * - Removed logentry from cancelled commit
- *
- * Revision 1.3 2001/06/03 19:12:24 oes
- * functions for new struct map, extended enlist_unique
- *
- * Revision 1.2 2001/06/01 18:49:17 jongfoster
- * Replaced "list_share" with "list" - the tiny memory gain was not
- * worth the extra complexity.
- *
- * Revision 1.1 2001/05/31 21:11:53 jongfoster
- * - Moved linked list support to new "list.c" file.
- * Structure definitions are still in project.h,
- * function prototypes are now in "list.h".
- * - Added support for "struct list_share", which is identical
- * to "struct list" except it saves memory by not duplicating
- * the strings. Obviously, this only works if there is some
- * other way of managing the memory used by the strings.
- * (These list_share lists are used for lists which last
- * for only 1 request, and where all the list entries are
- * just coming directly from entries in the actionsfile.)
- * Note that you still need to destroy list_share lists
- * properly to free the nodes - it's only the strings
- * which are shared.

- *
- * Revision 1.6 2001/08/05 16:06:20 jongfoster
- * Modifiying "struct map" so that there are now separate header and
- * "map_entry" structures. This means that functions which modify a
- * map no longer need to return a pointer to the modified map.
- * Also, it no longer reverses the order of the entries (which may be

- *
- * Revision 1.5 2001/07/29 18:43:08 jongfoster

- * free_map(), and extended enlist_unique
- *
- * Revision 1.2 2001/06/01 18:49:17 jongfoster
- * Replaced "list_share" with "list" - the tiny memory gain was not
- * worth the extra complexity.
- *
- * Revision 1.1 2001/05/31 21:11:53 jongfoster
- * - Moved linked list support to new "list.c" file.
- * Structure definitions are still in project.h,
- * function prototypes are now in "list.h".
- * - Added support for "struct list_share", which is identical
- * to "struct list" except it saves memory by not duplicating
- * the strings. Obviously, this only works if there is some
- * other way of managing the memory used by the strings.
- * (These list_share lists are used for lists which last
- * for only 1 request, and where all the list entries are
- * just coming directly from entries in the actionsfile.)
- * Note that you still need to destroy list_share lists
- * properly to free the nodes - it's only the strings
- * which are shared.

- * Revision 1.25 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 1.24 2001/10/23 21:40:30 jongfoster
- * Added support for enable-edit-actions and enable-remote-toggle config
- * file options.
- *
- * Revision 1.23 2001/10/07 15:36:00 oes
- * Introduced new config option "buffer-limit"
- *
- * Revision 1.22 2001/09/22 16:36:59 jongfoster
- * Removing unused parameter fs from read_config_line()
- *
- * Revision 1.21 2001/09/16 17:10:43 jongfoster
- * Moving function savearg() here, since it was the only thing left in
- * showargs.c.
- *
- * Revision 1.20 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:
- * - All feature #defines are now of the form FEATURE_xxx
- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.19 2001/07/15 17:45:16 jongfoster
- * Removing some unused #includes
- *
- * Revision 1.18 2001/07/13 14:01:14 oes
- * - Removed all #ifdef PCRS
- * - Removed vim-settings
- *
- * Revision 1.17 2001/06/29 13:31:03 oes
- * - Improved comments
- * - Fixed (actionsfile) and sorted hashes
- * - Introduced admin_address and proxy-info-url
- * as config parameters
- * - Renamed config->proxy_args_invocation (which didn't have
- * the invocation but the options!) to config->proxy_args
- * - Various adaptions
- * - Removed logentry from cancelled commit
- *
- * Revision 1.16 2001/06/09 10:55:28 jongfoster
- * Changing BUFSIZ ==> BUFFER_SIZE
- *
- * Revision 1.15 2001/06/07 23:13:40 jongfoster
- * Merging ACL and forward files into config file.
- * Cosmetic: Sorting config file options alphabetically.
- * Cosmetic: Adding brief syntax comments to config file options.
- *
- * Revision 1.14 2001/06/07 14:46:25 joergs
- * Missing make_path() added for re_filterfile.
- *
- * Revision 1.13 2001/06/05 22:33:54 jongfoster
- *
- * Fixed minor memory leak.
- * Also now uses make_path to prepend the pathnames.
- *
- * Revision 1.12 2001/06/05 20:04:09 jongfoster
- * Now uses _snprintf() in place of snprintf() under Win32.
- *
- * Revision 1.11 2001/06/04 18:31:58 swa
- * files are now prefixed with either `confdir' or `logdir'.
- * `make redhat-dist' replaces both entries confdir and logdir
- * with redhat values
- *
- * Revision 1.10 2001/06/03 19:11:54 oes
- * introduced confdir option
- *
- * Revision 1.9 2001/06/01 20:06:24 jongfoster
- * Removed support for "tinygif" option - moved to actions file.
- *
- * Revision 1.8 2001/05/31 21:27:13 jongfoster
- * Removed many options from the config file and into the
- * "actions" file: add_forwarded, suppress_vanilla_wafer,
- * wafer, add_header, user_agent, referer, from
- * Also globally replaced "permission" with "action".
- *
- * Revision 1.7 2001/05/29 09:50:24 jongfoster
- * Unified blocklist/imagelist/permissionslist.
- * File format is still under discussion, but the internal changes
- * are (mostly) done.
- *
- * Also modified interceptor behaviour:
- * - We now intercept all URLs beginning with one of the following
- * prefixes (and *only* these prefixes):
- * * http://i.j.b/
- * * http://ijbswa.sf.net/config/
- * * http://ijbswa.sourceforge.net/config/
- * - New interceptors "home page" - go to http://i.j.b/ to see it.
- * - Internal changes so that intercepted and fast redirect pages
- * are not replaced with an image.
- * - Interceptors now have the option to send a binary page direct
- * to the client. (i.e. ijb-send-banner uses this)
- * - Implemented show-url-info interceptor. (Which is why I needed
- * the above interceptors changes - a typical URL is
- * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
- * The previous mechanism would not have intercepted that, and
- * if it had been intercepted then it then it would have replaced
- * it with an image.)
- *
- * Revision 1.6 2001/05/26 00:28:36 jongfoster
- * Automatic reloading of config file.
- * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
- * Most of the global variables have been moved to a new
- * struct configuration_spec, accessed through csp->config->globalname
- * Most of the globals remaining are used by the Win32 GUI.
- *
- * Revision 1.5 2001/05/25 22:34:30 jongfoster
- * Hard tabs->Spaces
- *
- * Revision 1.4 2001/05/22 18:46:04 oes
- *
- * - Enabled filtering banners by size rather than URL
- * by adding patterns that replace all standard banner
- * sizes with the "Junkbuster" gif to the re_filterfile
- *
- * - Enabled filtering WebBugs by providing a pattern
- * which kills all 1x1 images
- *
- * - Added support for PCRE_UNGREEDY behaviour to pcrs,
- * which is selected by the (nonstandard and therefore
- * capital) letter 'U' in the option string.
- * It causes the quantifiers to be ungreedy by default.
- * Appending a ? turns back to greedy (!).
- *
- * - Added a new interceptor ijb-send-banner, which
- * sends back the "Junkbuster" gif. Without imagelist or
- * MSIE detection support, or if tinygif = 1, or the
- * URL isn't recognized as an imageurl, a lame HTML
- * explanation is sent instead.
- *
- * - Added new feature, which permits blocking remote
- * script redirects and firing back a local redirect
- * to the browser.
- * The feature is conditionally compiled, i.e. it
- * can be disabled with --disable-fast-redirects,
- * plus it must be activated by a "fast-redirects"
- * line in the config file, has its own log level
- * and of course wants to be displayed by show-proxy-args
- * Note: Boy, all the #ifdefs in 1001 locations and
- * all the fumbling with configure.in and acconfig.h
- * were *way* more work than the feature itself :-(
- *
- * - Because a generic redirect template was needed for
- * this, tinygif = 3 now uses the same.
- *
- * - Moved GIFs, and other static HTTP response templates
- * to project.h
- *
- * - Some minor fixes
- *
- * - Removed some >400 CRs again (Jon, you really worked
- * a lot! ;-)
- *
- * Revision 1.3 2001/05/20 01:21:20 jongfoster
- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.
- *
- * Revision 1.2 2001/05/17 23:01:01 oes
- * - Cleaned CRLF's from the sources and related files
- *
- * Revision 1.1.1.1 2001/05/15 13:58:58 oes
- * Initial import of version 2.9.3 source tree
- *
- *

- * Revision 1.9 2002/03/16 23:54:06 jongfoster
- * Adding graceful termination feature, to help look for memory leaks.
- * If you enable this (which, by design, has to be done by hand
- * editing config.h) and then go to http://i.j.b/die, then the program
- * will exit cleanly after the *next* request. It should free all the
- * memory that was used.
- *
- * Revision 1.8 2001/12/30 14:07:32 steudten
- * - Add signal handling (unix)
- * - Add SIGHUP handler (unix)
- * - Add creation of pidfile (unix)
- * - Add action 'top' in rc file (RH)
- * - Add entry 'SIGNALS' to manpage
- * - Add exit message to logfile (unix)
- *
- * Revision 1.7 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:
- * - All feature #defines are now of the form FEATURE_xxx
- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.6 2001/07/29 18:58:15 jongfoster
- * Removing nested #includes, adding forward declarations for needed
- * structures, and changing the #define _FILENAME_H to FILENAME_H_INCLUDED.
- *
- * Revision 1.5 2001/05/26 00:28:36 jongfoster
- * Automatic reloading of config file.
- * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
- * Most of the global variables have been moved to a new
- * struct configuration_spec, accessed through csp->config->globalname
- * Most of the globals remaining are used by the Win32 GUI.
- *
- * Revision 1.4 2001/05/22 18:46:04 oes
- *
- * - Enabled filtering banners by size rather than URL
- * by adding patterns that replace all standard banner
- * sizes with the "Junkbuster" gif to the re_filterfile
- *
- * - Enabled filtering WebBugs by providing a pattern
- * which kills all 1x1 images
- *
- * - Added support for PCRE_UNGREEDY behaviour to pcrs,
- * which is selected by the (nonstandard and therefore
- * capital) letter 'U' in the option string.
- * It causes the quantifiers to be ungreedy by default.
- * Appending a ? turns back to greedy (!).
- *
- * - Added a new interceptor ijb-send-banner, which
- * sends back the "Junkbuster" gif. Without imagelist or
- * MSIE detection support, or if tinygif = 1, or the
- * URL isn't recognized as an imageurl, a lame HTML
- * explanation is sent instead.
- *
- * - Added new feature, which permits blocking remote
- * script redirects and firing back a local redirect
- * to the browser.
- * The feature is conditionally compiled, i.e. it
- * can be disabled with --disable-fast-redirects,
- * plus it must be activated by a "fast-redirects"
- * line in the config file, has its own log level
- * and of course wants to be displayed by show-proxy-args
- * Note: Boy, all the #ifdefs in 1001 locations and
- * all the fumbling with configure.in and acconfig.h
- * were *way* more work than the feature itself :-(
- *
- * - Because a generic redirect template was needed for
- * this, tinygif = 3 now uses the same.
- *
- * - Moved GIFs, and other static HTTP response templates
- * to project.h
- *
- * - Some minor fixes
- *
- * - Removed some >400 CRs again (Jon, you really worked
- * a lot! ;-)
- *
- * Revision 1.3 2001/05/20 01:21:20 jongfoster
- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.
- *
- * Revision 1.2 2001/05/17 23:01:01 oes
- * - Cleaned CRLF's from the sources and related files
- *
- * Revision 1.1.1.1 2001/05/15 13:58:58 oes
- * Initial import of version 2.9.3 source tree

- * Moving edit_read_line() and simple_read_line() to loaders.c, and

- * on all platforms.
- *
- * Modifying read_config_line() (without changing it's prototype) to

- * Moving all our URL and URL pattern parsing code to urlmatch.c.

- * Revision 1.30 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.

- * Cosmetic: Moving unloader funcs next to their
- * respective loader funcs
- *
- * Revision 1.14 2001/06/01 03:27:04 oes
- * Fixed line continuation problem
- *
- * Revision 1.13 2001/05/31 21:28:49 jongfoster
- * Removed all permissionsfile code - it's now called the actions
- * file, and (almost) all the code is in actions.c
- *

- *
- * - Enhanced domain part globbing with infix and prefix asterisk
- * matching and optional unanchored operation

- * - load_config_line() and load_permissions_file() now use chomp()
- *
- * Revision 1.10 2001/05/29 09:50:24 jongfoster
- * Unified blocklist/imagelist/permissionslist.
- * File format is still under discussion, but the internal changes
- * are (mostly) done.
- *
- * Also modified interceptor behaviour:
- * - We now intercept all URLs beginning with one of the following
- * prefixes (and *only* these prefixes):
- * * http://i.j.b/
- * * http://ijbswa.sf.net/config/
- * * http://ijbswa.sourceforge.net/config/
- * - New interceptors "home page" - go to http://i.j.b/ to see it.
- * - Internal changes so that intercepted and fast redirect pages
- * are not replaced with an image.
- * - Interceptors now have the option to send a binary page direct
- * to the client. (i.e. ijb-send-banner uses this)
- * - Implemented show-url-info interceptor. (Which is why I needed
- * the above interceptors changes - a typical URL is
- * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
- * The previous mechanism would not have intercepted that, and
- * if it had been intercepted then it then it would have replaced
- * it with an image.)
- *
- * Revision 1.9 2001/05/26 17:12:07 jongfoster
- * Fatal errors loading configuration files now give better error messages.
- *
- * Revision 1.8 2001/05/26 00:55:20 jongfoster
- * Removing duplicated code. load_forwardfile() now uses create_url_spec()
- *
- * Revision 1.7 2001/05/26 00:28:36 jongfoster
- * Automatic reloading of config file.
- * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
- * Most of the global variables have been moved to a new
- * struct configuration_spec, accessed through csp->config->globalname
- * Most of the globals remaining are used by the Win32 GUI.
- *
- * Revision 1.6 2001/05/23 12:27:33 oes
- *
- * Fixed ugly indentation of my last changes
- *
- * Revision 1.5 2001/05/23 10:39:05 oes
- * - Added support for escaping the comment character
- * in config files by a backslash
- * - Added support for line continuation in config
- * files
- * - Fixed a buffer overflow bug with long config lines
- *
- * Revision 1.4 2001/05/22 18:56:28 oes
- * CRLF -> LF
- *
- * Revision 1.3 2001/05/20 01:21:20 jongfoster
- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.

- * Description : Read a single line from a file and return it.
- * This is basically a version of fgets() that malloc()s

- * always be a multiple of BUFFER_SIZE bytes long.
- * Therefore if you are going to keep the string for
- * an extended period of time, you should probably
- * strdup() it and free() the original, to save memory.
- *
- *
- * Parameters :
- * 1 : dest = destination for newly malloc'd pointer to
- * line data. Will be set to NULL on error.
- * 2 : fp = File to read from
- * 3 : newline = Standard for newlines in the file.
- * Will be unchanged if it's value on input is not
- * NEWLINE_UNKNOWN.
- * On output, may be changed from NEWLINE_UNKNOWN to
- * actual convention in file.
- *
- * Returns : JB_ERR_OK on success
- * JB_ERR_MEMORY on out-of-memory
- * JB_ERR_FILE on EOF.

-/*********************************************************************
- *
- * Function : edit_read_line
- *
- * Description : Read a single non-empty line from a file and return
- * it. Trims comments, leading and trailing whitespace
- * and respects escaping of newline and comment char.
- * Provides the line in 2 alternative forms: raw and
- * preprocessed.
- * - raw is the raw data read from the file. If the
- * line is not modified, then this should be written
- * to the new file.
- * - prefix is any comments and blank lines that were
- * read from the file. If the line is modified, then
- * this should be written out to the file followed
- * by the modified data. (If this string is non-empty
- * then it will have a newline at the end).
- * - data is the actual data that will be parsed
- * further by appropriate routines.
- * On EOF, the 3 strings will all be set to NULL and
- * 0 will be returned.
- *
- * Parameters :
- * 1 : fp = File to read from
- * 2 : raw_out = destination for newly malloc'd pointer to
- * raw line data. May be NULL if you don't want it.
- * 3 : prefix_out = destination for newly malloc'd pointer to
- * comments. May be NULL if you don't want it.
- * 4 : data_out = destination for newly malloc'd pointer to
- * line data with comments and leading/trailing spaces
- * removed, and line continuation performed. May be
- * NULL if you don't want it.
- * 5 : newline = Standard for newlines in the file.
- * On input, set to value to use or NEWLINE_UNKNOWN.
- * On output, may be changed from NEWLINE_UNKNOWN to
- * actual convention in file. May be NULL if you
- * don't want it.
- * 6 : line_number = Line number in file. In "lines" as
- * reported by a text editor, not lines containing data.
- *
- * Returns : JB_ERR_OK on success
- * JB_ERR_MEMORY on out-of-memory

- * Revisions :
- * $Log: loaders.h,v $
- * Revision 1.18 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.17 2002/03/16 23:54:06 jongfoster
- * Adding graceful termination feature, to help look for memory leaks.
- * If you enable this (which, by design, has to be done by hand
- * editing config.h) and then go to http://i.j.b/die, then the program
- * will exit cleanly after the *next* request. It should free all the
- * memory that was used.
- *
- * Revision 1.16 2002/03/07 03:46:17 oes
- * Fixed compiler warnings
- *
- * Revision 1.15 2002/01/22 23:46:18 jongfoster
- * Moving edit_read_line() and simple_read_line() to loaders.c, and
- * extending them to support reading MS-DOS, Mac and UNIX style files
- * on all platforms.
- *
- * Modifying read_config_line() (without changing it's prototype) to
- * be a trivial wrapper for edit_read_line(). This means that we have
- * one function to read a line and handle comments, which is common
- * between the initialization code and the edit interface.
- *
- * Revision 1.14 2002/01/17 21:03:08 jongfoster
- * Moving all our URL and URL pattern parsing code to urlmatch.c.
- *
- * Renaming free_url to free_url_spec, since it frees a struct url_spec.
- *
- * Revision 1.13 2001/12/30 14:07:32 steudten
- * - Add signal handling (unix)
- * - Add SIGHUP handler (unix)
- * - Add creation of pidfile (unix)
- * - Add action 'top' in rc file (RH)
- * - Add entry 'SIGNALS' to manpage
- * - Add exit message to logfile (unix)
- *
- * Revision 1.12 2001/11/07 00:02:13 steudten
- * Add line number in error output for lineparsing for
- * actionsfile and configfile.
- * Special handling for CLF added.
- *
- * Revision 1.11 2001/10/23 21:38:53 jongfoster
- * Adding error-checking to create_url_spec()
- *
- * Revision 1.10 2001/09/22 16:36:59 jongfoster
- * Removing unused parameter fs from read_config_line()
- *
- * Revision 1.9 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:
- * - All feature #defines are now of the form FEATURE_xxx
- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.8 2001/07/29 18:58:15 jongfoster
- * Removing nested #includes, adding forward declarations for needed
- * structures, and changing the #define _FILENAME_H to FILENAME_H_INCLUDED.
- *
- * Revision 1.7 2001/07/13 14:01:54 oes
- * Removed all #ifdef PCRS
- *
- * Revision 1.6 2001/06/07 23:14:38 jongfoster
- * Removing ACL and forward file loaders - these files have
- * been merged into the config file.
- *
- * Revision 1.5 2001/05/31 21:28:49 jongfoster
- * Removed all permissionsfile code - it's now called the actions
- * file, and (almost) all the code is in actions.c
- *
- * Revision 1.4 2001/05/29 09:50:24 jongfoster
- * Unified blocklist/imagelist/permissionslist.
- * File format is still under discussion, but the internal changes
- * are (mostly) done.
- *
- * Also modified interceptor behaviour:
- * - We now intercept all URLs beginning with one of the following
- * prefixes (and *only* these prefixes):
- * * http://i.j.b/
- * * http://ijbswa.sf.net/config/
- * * http://ijbswa.sourceforge.net/config/
- * - New interceptors "home page" - go to http://i.j.b/ to see it.
- * - Internal changes so that intercepted and fast redirect pages
- * are not replaced with an image.
- * - Interceptors now have the option to send a binary page direct
- * to the client. (i.e. ijb-send-banner uses this)
- * - Implemented show-url-info interceptor. (Which is why I needed
- * the above interceptors changes - a typical URL is
- * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
- * The previous mechanism would not have intercepted that, and
- * if it had been intercepted then it then it would have replaced
- * it with an image.)
- *
- * Revision 1.3 2001/05/26 00:28:36 jongfoster
- * Automatic reloading of config file.
- * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
- * Most of the global variables have been moved to a new
- * struct configuration_spec, accessed through csp->config->globalname
- * Most of the globals remaining are used by the Win32 GUI.
- *
- * Revision 1.2 2001/05/20 01:21:20 jongfoster
- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.
- *
- * Revision 1.1.1.1 2001/05/15 13:59:00 oes
- * Initial import of version 2.9.3 source tree

- *
- * Function : string_append
- *
- * Description : Reallocate target_string and append text to it.
- * This makes it easier to append to malloc'd strings.
- * This is similar to the (removed) strsav(), but
- * running out of memory isn't catastrophic.
- *
- * Programming style:
- *
- * The following style provides sufficient error
- * checking for this routine, with minimal clutter
- * in the source code. It is recommended if you
- * have many calls to this function:
- *
- * char * s = strdup(...); // don't check for error
- * string_append(&s, ...); // don't check for error
- * string_append(&s, ...); // don't check for error
- * string_append(&s, ...); // don't check for error
- * if (NULL == s) { ... handle error ... }
- *
- * OR, equivalently:
- *
- * char * s = strdup(...); // don't check for error
- * string_append(&s, ...); // don't check for error
- * string_append(&s, ...); // don't check for error
- * if (string_append(&s, ...)) {... handle error ...}
- *
- * Parameters :
- * 1 : target_string = Pointer to old text that is to be
- * extended. *target_string will be free()d by this
- * routine. target_string must be non-NULL.
- * If *target_string is NULL, this routine will
- * do nothing and return with an error - this allows
- * you to make many calls to this routine and only
- * check for errors after the last one.
- * 2 : text_to_append = Text to be appended to old.
- * Must not be NULL.
- *
- * Returns : JB_ERR_OK on success, and sets *target_string
- * to newly malloc'ed appended string. Caller
- * must free(*target_string).
- * JB_ERR_MEMORY on out-of-memory. (And free()s
- * *target_string and sets it to NULL).

- *
- * Description : Join two strings together. Frees BOTH the original

- * For comparison, string_append requires that the

- * Rationale: Too often, we want to do

- * It also leaks memory. Proper checking is cumbersome.
- * The solution: string_join(s, html_encode(s2)) is safe,
- * and will free the memory allocated by html_encode().
- *
- * Parameters :
- * 1 : target_string = Pointer to old text that is to be

- * What follows is a portable snprintf routine, written by Mark Martinec.

- * Anyone who needs it can add a define for themselves... so far, only

-
- snprintf.c
- - a portable implementation of snprintf,
- including vsnprintf.c, asnprintf, vasnprintf, asprintf, vasprintf
-
- snprintf is a routine to convert numeric and string arguments to
- formatted strings. It is similar to sprintf(3) provided in a system's
- C library, yet it requires an additional argument - the buffer size -
- and it guarantees never to store anything beyond the given buffer,
- regardless of the format or arguments to be formatted. Some newer
- operating systems do provide snprintf in their C library, but many do
- not or do provide an inadequate (slow or idiosyncratic) version, which
- calls for a portable implementation of this routine.

- * Unified blocklist/imagelist/permissionslist.
- * File format is still under discussion, but the internal changes
- * are (mostly) done.
- *
- * Also modified interceptor behaviour:
- * - We now intercept all URLs beginning with one of the following
- * prefixes (and *only* these prefixes):
- * * http://i.j.b/
- * * http://ijbswa.sf.net/config/
- * * http://ijbswa.sourceforge.net/config/
- * - New interceptors "home page" - go to http://i.j.b/ to see it.
- * - Internal changes so that intercepted and fast redirect pages
- * are not replaced with an image.
- * - Interceptors now have the option to send a binary page direct
- * to the client. (i.e. ijb-send-banner uses this)
- * - Implemented show-url-info interceptor. (Which is why I needed
- * the above interceptors changes - a typical URL is
- * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
- * The previous mechanism would not have intercepted that, and
- * if it had been intercepted then it then it would have replaced
- * it with an image.)
- *
- * Revision 1.1.1.1 2001/05/15 13:59:00 oes
- * Initial import of version 2.9.3 source tree

- * Revisions :
- * $Log: parsers.c,v $
- * Revision 1.55 2002/05/08 16:01:07 oes
- * Optimized add_to_iob:
- * - Use realloc instead of malloc(), memcpy(), free()
- * - Expand to powers of two if possible, to get
- * O(log n) reallocs instead of O(n).
- * - Moved check for buffer limit here from chat
- * - Report failure via returncode
- *
- * Revision 1.54 2002/04/02 15:03:16 oes
- * Tiny code cosmetics
- *
- * Revision 1.53 2002/03/26 22:29:55 swa

- * name change related issues
- *
- * Revision 1.51 2002/03/13 00:27:05 jongfoster
- * Killing warnings
- *
- * Revision 1.50 2002/03/12 01:45:35 oes
- * More verbose logging
- *
- * Revision 1.49 2002/03/09 20:03:52 jongfoster
- * - Making various functions return int rather than size_t.
- * (Undoing a recent change). Since size_t is unsigned on
- * Windows, functions like read_socket that return -1 on
- * error cannot return a size_t.
- *
- * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
- * crashes, and also frequently caused JB to jump to 100%
- * CPU and stay there. (Because it thought it had just
- * read ((unsigned)-1) == 4Gb of data...)
- *
- * - The signature of write_socket has changed, it now simply
- * returns success=0/failure=nonzero.
- *
- * - Trying to get rid of a few warnings --with-debug on
- * Windows, I've introduced a new type "jb_socket". This is
- * used for the socket file descriptors. On Windows, this
- * is SOCKET (a typedef for unsigned). Everywhere else, it's
- * an int. The error value can't be -1 any more, so it's
- * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
- * Windows it maps to the #define INVALID_SOCKET.)
- *
- * - The signature of bind_port has changed.
- *
- * Revision 1.48 2002/03/07 03:46:53 oes
- * Fixed compiler warnings etc
- *
- * Revision 1.47 2002/02/20 23:15:13 jongfoster
- * Parsing functions now handle out-of-memory gracefully by returning
- * an error code.
- *
- * Revision 1.46 2002/01/17 21:03:47 jongfoster
- * Moving all our URL and URL pattern parsing code to urlmatch.c.
- *
- * Revision 1.45 2002/01/09 14:33:03 oes
- * Added support for localtime_r.
- *
- * Revision 1.44 2001/12/14 01:22:54 steudten
- * Remove 'user:pass@' from 'proto://user:pass@host' for the
- * new added header 'Host: ..'. (See Req ID 491818)
- *
- * Revision 1.43 2001/11/23 00:26:38 jongfoster
- * Fixing two really stupid errors in my previous commit
- *
- * Revision 1.42 2001/11/22 21:59:30 jongfoster

- *
- * Revision 1.41 2001/11/05 23:43:05 steudten
- * Add time+date to log files.
- *
- * Revision 1.40 2001/10/26 20:13:09 jongfoster
- * ctype.h is needed in Windows, too.
- *
- * Revision 1.39 2001/10/26 17:40:04 oes
- * Introduced get_header_value()
- * Removed http->user_agent, csp->referrer and csp->accept_types
- * Removed client_accept()
- *
- * Revision 1.38 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 1.37 2001/10/23 21:36:02 jongfoster
- * Documenting sed()'s error behaviou (doc change only)
- *
- * Revision 1.36 2001/10/13 12:51:51 joergs
- * Removed client_host, (was only required for the old 2.0.2-11 http://noijb.
- * force-load), instead crumble Host: and add it (again) in client_host_adder
- * (in case we get a HTTP/1.0 request without Host: header and forward it to
- * a HTTP/1.1 server/proxy).
- *
- * Revision 1.35 2001/10/09 22:39:21 jongfoster
- * assert.h is also required under Win32, so moving out of #ifndef _WIN32
- * block.
- *
- * Revision 1.34 2001/10/07 18:50:55 oes
- * Added server_content_encoding, renamed server_transfer_encoding
- *
- * Revision 1.33 2001/10/07 18:04:49 oes
- * Changed server_http11 to server_http and its pattern to "HTTP".
- * Additional functionality: it now saves the HTTP status into
- * csp->http->status and sets CT_TABOO for Status 206 (partial range)
- *
- * Revision 1.32 2001/10/07 15:43:28 oes
- * Removed FEATURE_DENY_GZIP and replaced it with client_accept_encoding,
- * client_te and client_accept_encoding_adder, triggered by the new
- * +no-compression action. For HTTP/1.1 the Accept-Encoding header is
- * changed to allow only identity and chunked, and the TE header is
- * crunched. For HTTP/1.0, Accept-Encoding is crunched.
- *
- * parse_http_request no longer does anything than parsing. The rewriting
- * of http->cmd and version mangling are gone. It now also recognizes
- * the put and delete methods and saves the url in http->url. Removed
- * unused variable.
- *
- * renamed content_type and content_length to have the server_ prefix
- *
- * server_content_type now only works if csp->content_type != CT_TABOO
- *
- * added server_transfer_encoding, which
- * - Sets CT_TABOO to prohibit filtering if encoding compresses
- * - Raises the CSP_FLAG_CHUNKED flag if Encoding is "chunked"
- * - Change from "chunked" to "identity" if body was chunked
- * but has been de-chunked for filtering.
- *
- * added server_content_md5 which crunches any Content-MD5 headers
- * if the body was modified.
- *
- * made server_http11 conditional on +downgrade action
- *
- * Replaced 6 boolean members of csp with one bitmap (csp->flags)
- *
- * Revision 1.31 2001/10/05 14:25:02 oes
- * Crumble Keep-Alive from Server
- *
- * Revision 1.30 2001/09/29 12:56:03 joergs
- * IJB now changes HTTP/1.1 to HTTP/1.0 in requests and answers.
- *
- * Revision 1.29 2001/09/24 21:09:24 jongfoster
- * Fixing 2 memory leaks that Guy spotted, where the paramater to
- * enlist() was not being free()d.
- *
- * Revision 1.28 2001/09/22 16:32:28 jongfoster
- * Removing unused #includes.
- *
- * Revision 1.27 2001/09/20 15:45:25 steudten
- *
- * add casting from size_t to int for printf()
- * remove local variable shadow s2
- *
- * Revision 1.26 2001/09/16 17:05:14 jongfoster
- * Removing unused #include showarg.h
- *
- * Revision 1.25 2001/09/16 13:21:27 jongfoster
- * Changes to use new list functions.
- *
- * Revision 1.24 2001/09/13 23:05:50 jongfoster
- * Changing the string paramater to the header parsers a "const".
- *
- * Revision 1.23 2001/09/12 18:08:19 steudten
- *
- * In parse_http_request() header rewriting miss the host value, so
- * from http://www.mydomain.com the result was just " / " not
- * http://www.mydomain.com/ in case we forward.
- *
- * Revision 1.22 2001/09/10 10:58:53 oes
- * Silenced compiler warnings
- *
- * Revision 1.21 2001/07/31 14:46:00 oes
- * - Persistant connections now suppressed
- * - sed() no longer appends empty header to csp->headers
- *
- * Revision 1.20 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:
- * - All feature #defines are now of the form FEATURE_xxx
- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.19 2001/07/25 17:21:54 oes
- * client_uagent now saves copy of User-Agent: header value
- *
- * Revision 1.18 2001/07/13 14:02:46 oes
- * - Included fix to repair broken HTTP requests that
- * don't contain a path, not even '/'.
- * - Removed all #ifdef PCRS
- * - content_type now always inspected and classified as
- * text, gif or other.
- * - formatting / comments
- *
- * Revision 1.17 2001/06/29 21:45:41 oes
- * Indentation, CRLF->LF, Tab-> Space
- *
- * Revision 1.16 2001/06/29 13:32:42 oes
- * - Fixed a comment
- * - Adapted free_http_request
- * - Removed logentry from cancelled commit
- *
- * Revision 1.15 2001/06/03 19:12:38 oes
- * deleted const struct interceptors
- *
- * Revision 1.14 2001/06/01 18:49:17 jongfoster
- * Replaced "list_share" with "list" - the tiny memory gain was not
- * worth the extra complexity.
- *
- * Revision 1.13 2001/05/31 21:30:33 jongfoster
- * Removed list code - it's now in list.[ch]
- * Renamed "permission" to "action", and changed many features
- * to use the actions file rather than the global config.
- *
- * Revision 1.12 2001/05/31 17:33:13 oes
- *
- * CRLF -> LF
- *
- * Revision 1.11 2001/05/29 20:11:19 joergs
- * '/ * inside comment' warning removed.
- *
- * Revision 1.10 2001/05/29 09:50:24 jongfoster
- * Unified blocklist/imagelist/permissionslist.
- * File format is still under discussion, but the internal changes
- * are (mostly) done.
- *
- * Also modified interceptor behaviour:
- * - We now intercept all URLs beginning with one of the following
- * prefixes (and *only* these prefixes):
- * * http://i.j.b/
- * * http://ijbswa.sf.net/config/
- * * http://ijbswa.sourceforge.net/config/
- * - New interceptors "home page" - go to http://i.j.b/ to see it.
- * - Internal changes so that intercepted and fast redirect pages
- * are not replaced with an image.
- * - Interceptors now have the option to send a binary page direct
- * to the client. (i.e. ijb-send-banner uses this)
- * - Implemented show-url-info interceptor. (Which is why I needed
- * the above interceptors changes - a typical URL is
- * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
- * The previous mechanism would not have intercepted that, and
- * if it had been intercepted then it then it would have replaced
- * it with an image.)
- *
- * Revision 1.9 2001/05/28 17:26:33 jongfoster
- * Fixing segfault if last header was crunched.
- * Fixing Windows build (snprintf() is _snprintf() under Win32, but we
- * can use the cross-platform sprintf() instead.)
- *
- * Revision 1.8 2001/05/27 22:17:04 oes
- *
- * - re_process_buffer no longer writes the modified buffer
- * to the client, which was very ugly. It now returns the
- * buffer, which it is then written by chat.
- *
- * - content_length now adjusts the Content-Length: header
- * for modified documents rather than crunch()ing it.
- * (Length info in csp->content_length, which is 0 for
- * unmodified documents)
- *
- * - For this to work, sed() is called twice when filtering.
- *
- * Revision 1.7 2001/05/27 13:19:06 oes
- * Patched Joergs solution for the content-length in.
- *
- * Revision 1.6 2001/05/26 13:39:32 jongfoster
- * Only crunches Content-Length header if applying RE filtering.
- * Without this fix, Microsoft Windows Update wouldn't work.
- *
- * Revision 1.5 2001/05/26 00:28:36 jongfoster
- * Automatic reloading of config file.
- * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
- * Most of the global variables have been moved to a new
- * struct configuration_spec, accessed through csp->config->globalname
- * Most of the globals remaining are used by the Win32 GUI.
- *
- * Revision 1.4 2001/05/22 18:46:04 oes
- *
- * - Enabled filtering banners by size rather than URL
- * by adding patterns that replace all standard banner
- * sizes with the "Junkbuster" gif to the re_filterfile
- *
- * - Enabled filtering WebBugs by providing a pattern
- * which kills all 1x1 images
- *
- * - Added support for PCRE_UNGREEDY behaviour to pcrs,
- * which is selected by the (nonstandard and therefore
- * capital) letter 'U' in the option string.
- * It causes the quantifiers to be ungreedy by default.
- * Appending a ? turns back to greedy (!).
- *
- * - Added a new interceptor ijb-send-banner, which
- * sends back the "Junkbuster" gif. Without imagelist or
- * MSIE detection support, or if tinygif = 1, or the
- * URL isn't recognized as an imageurl, a lame HTML
- * explanation is sent instead.
- *
- * - Added new feature, which permits blocking remote
- * script redirects and firing back a local redirect
- * to the browser.
- * The feature is conditionally compiled, i.e. it
- * can be disabled with --disable-fast-redirects,
- * plus it must be activated by a "fast-redirects"
- * line in the config file, has its own log level
- * and of course wants to be displayed by show-proxy-args
- * Note: Boy, all the #ifdefs in 1001 locations and
- * all the fumbling with configure.in and acconfig.h
- * were *way* more work than the feature itself :-(
- *
- * - Because a generic redirect template was needed for
- * this, tinygif = 3 now uses the same.
- *
- * - Moved GIFs, and other static HTTP response templates
- * to project.h
- *
- * - Some minor fixes
- *
- * - Removed some >400 CRs again (Jon, you really worked
- * a lot! ;-)
- *
- * Revision 1.3 2001/05/20 01:21:20 jongfoster
- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.
- *
- * Revision 1.2 2001/05/17 23:02:36 oes
- * - Made referrer option accept 'L' as a substitute for '§'
- *
- * Revision 1.1.1.1 2001/05/15 13:59:01 oes
- * Initial import of version 2.9.3 source tree

- * Revision 1.24 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.23 2002/03/13 00:27:05 jongfoster
- * Killing warnings
- *
- * Revision 1.22 2002/03/09 20:03:52 jongfoster
- * - Making various functions return int rather than size_t.
- * (Undoing a recent change). Since size_t is unsigned on
- * Windows, functions like read_socket that return -1 on
- * error cannot return a size_t.
- *
- * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
- * crashes, and also frequently caused JB to jump to 100%
- * CPU and stay there. (Because it thought it had just
- * read ((unsigned)-1) == 4Gb of data...)
- *
- * - The signature of write_socket has changed, it now simply
- * returns success=0/failure=nonzero.
- *
- * - Trying to get rid of a few warnings --with-debug on
- * Windows, I've introduced a new type "jb_socket". This is
- * used for the socket file descriptors. On Windows, this
- * is SOCKET (a typedef for unsigned). Everywhere else, it's
- * an int. The error value can't be -1 any more, so it's
- * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
- * Windows it maps to the #define INVALID_SOCKET.)
- *
- * - The signature of bind_port has changed.
- *
- * Revision 1.21 2002/03/07 03:46:17 oes
- * Fixed compiler warnings
- *
- * Revision 1.20 2002/02/20 23:15:13 jongfoster

- * IJB now changes HTTP/1.1 to HTTP/1.0 in requests and answers.
- *
- * Revision 1.12 2001/09/13 23:05:50 jongfoster
- * Changing the string paramater to the header parsers a "const".
- *
- * Revision 1.11 2001/07/31 14:46:53 oes
- * Added prototype for connection_close_adder
- *
- * Revision 1.10 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:
- * - All feature #defines are now of the form FEATURE_xxx
- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.9 2001/07/29 18:43:08 jongfoster

- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.

- *
- * Revision 1.13 2001/09/06 14:05:59 oes
- * Fixed silly bug
- *
- * Revision 1.12 2001/08/18 11:35:00 oes
- * - Introduced pcrs_strerror()
- * - made some NULL arguments non-fatal
- * - added support for \n \r \e \b \t \f \a \0 in substitute
- * - made quoting adhere to standard rules
- * - added warning for bad backrefs
- * - added pcrs_execute_list()
- * - fixed comments
- * - bugfix & cosmetics
- *
- * Revision 1.11 2001/08/15 15:32:03 oes
- * - Added support for Perl's special variables $+, $' and $`
- * - Improved the substitute parser
- * - Replaced the hard limit for the maximum number of matches
- * by dynamic reallocation
- *
- * Revision 1.10 2001/08/05 13:13:11 jongfoster
- * Making parameters "const" where possible.
- *
- * Revision 1.9 2001/07/18 17:27:00 oes
- * Changed interface; Cosmetics
- *
- * Revision 1.8 2001/06/29 21:45:41 oes
- * Indentation, CRLF->LF, Tab-> Space
- *
- * Revision 1.7 2001/06/29 13:33:04 oes
- * - Cleaned up, renamed and reordered functions,
- * improved comments
- * - Removed my_strsep
- * - Replaced globalflag with a general flags int
- * that holds PCRS_GLOBAL, PCRS_SUCCESS, and PCRS_TRIVIAL
- * - Introduced trivial option that will prevent pcrs
- * from honouring backreferences in the substitute,
- * which is useful for large substitutes that are
- * red in from somewhere and saves the pain of escaping
- * the backrefs
- * - Introduced convenience function pcrs_free_joblist()
- * - Split pcrs_make_job() into pcrs_compile(), which still
- * takes a complete s/// comand as argument and parses it,
- * and a new function pcrs_make_job, which takes the
- * three separate components. This should make for a
- * much friendlier frontend.
- * - Removed create_pcrs_job() which was useless
- * - Fixed a bug in pcrs_execute
- * - Success flag is now handled by pcrs instead of user
- *
- * Revision 1.6 2001/06/03 19:12:45 oes
- * added FIXME
- *
- * Revision 1.5 2001/05/29 09:50:24 jongfoster
- * (Fixed one int -> size_t)
- *
- * Revision 1.4 2001/05/25 14:12:40 oes
- * Fixed bug: Empty substitutes now detected
- *
- * Revision 1.3 2001/05/25 11:03:55 oes
- * Added sanity check for NULL jobs to pcrs_exec_substitution
- *
- * Revision 1.2 2001/05/22 18:46:04 oes
- *
- * Added support for PCRE_UNGREEDY behaviour to pcrs,
- * which is selected by the (nonstandard and therefore
- * capital) letter 'U' in the option string.
- * It causes the quantifiers to be ungreedy by default.
- * Appending a ? turns back to greedy (!).
- *
- * Revision 1.1.1.1 2001/05/15 13:59:02 oes
- * Initial import of version 2.9.3 source tree

- * Revision 1.57 2002/03/16 20:28:34 oes
- * Added descriptions to the filters so users will know what they select in the cgi editor
- *
- * Revision 1.56 2002/03/13 20:27:30 oes
- * Fixing bug with CT_TABOO
- *
- * Revision 1.55 2002/03/12 01:42:50 oes
- * Introduced modular filters
- *
- * Revision 1.54 2002/03/09 20:03:52 jongfoster
- * - Making various functions return int rather than size_t.
- * (Undoing a recent change). Since size_t is unsigned on
- * Windows, functions like read_socket that return -1 on
- * error cannot return a size_t.
- *
- * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
- * crashes, and also frequently caused JB to jump to 100%
- * CPU and stay there. (Because it thought it had just
- * read ((unsigned)-1) == 4Gb of data...)
- *
- * - The signature of write_socket has changed, it now simply
- * returns success=0/failure=nonzero.
- *
- * - Trying to get rid of a few warnings --with-debug on
- * Windows, I've introduced a new type "jb_socket". This is
- * used for the socket file descriptors. On Windows, this
- * is SOCKET (a typedef for unsigned). Everywhere else, it's
- * an int. The error value can't be -1 any more, so it's
- * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
- * Windows it maps to the #define INVALID_SOCKET.)
- *
- * - The signature of bind_port has changed.
- *
- * Revision 1.53 2002/03/08 16:48:55 oes
- * Added FEATURE_NO_GIFS and BUILTIN_IMAGE_MIMETYPE
- *
- * Revision 1.52 2002/03/07 03:46:17 oes
- * Fixed compiler warnings
- *
- * Revision 1.51 2002/03/05 04:52:42 oes

- * Deleted PID_FILE_NAME
- *
- * Revision 1.48 2002/03/03 14:50:40 oes
- * Fixed CLF logging: Added ocmd member for client's request to struct http_request
- *
- * Revision 1.47 2002/02/20 23:15:13 jongfoster
- * Parsing functions now handle out-of-memory gracefully by returning
- * an error code.
- *
- * Revision 1.46 2002/01/17 21:06:09 jongfoster
- * Now #defining the URLs of the config interface
- *
- * Minor changes to struct http_request and struct url_spec due to
- * standardizing that struct http_request is used to represent a URL, and
- * struct url_spec is used to represent a URL pattern. (Before, URLs were
- * represented as seperate variables and a partially-filled-in url_spec).
- *
- * Revision 1.45 2002/01/09 14:33:27 oes
- * Added HOSTENT_BUFFER_SIZE
- *
- * Revision 1.44 2001/12/30 14:07:32 steudten

- * - Add entry 'SIGNALS' to manpage
- * - Add exit message to logfile (unix)
- *
- * Revision 1.43 2001/11/22 21:57:51 jongfoster
- * Making action_spec->flags into an unsigned long rather than just an
- * unsigned int.
- * Adding ACTION_NO_COOKIE_KEEP
- *
- * Revision 1.42 2001/11/05 21:42:41 steudten
- * Include DBG() macro.
- *
- * Revision 1.41 2001/10/28 19:12:06 jongfoster
- * Adding ijb_toupper()
- *
- * Revision 1.40 2001/10/26 17:40:47 oes
- * Moved ijb_isspace and ijb_tolower to project.h
- * Removed http->user_agent, csp->referrer and csp->accept_types
- *
- * Revision 1.39 2001/10/25 03:45:02 david__schmidt
- * Adding a (void*) cast to freez() because Visual Age C++ won't expand the
- * macro when called with a cast; so moving the cast to the macro def'n
- * seems to both eliminate compiler warnings (on darwin and OS/2, anyway) and
- * doesn't make macro expansion complain. Hope this works for everyone else
- * too...
- *
- * Revision 1.38 2001/10/23 21:19:04 jongfoster
- * New error-handling support: jb_err type and JB_ERR_xxx constants

- * Adding a few comments
- *

- * members
- *
- * Added CT_TABOO
- *
- * Added ACTION_DOWNGRADE and ACTION_NO_COMPRESSION
- *
- * Replaced struct client_state members rejected,
- * force, active and toggled_on with "flags" bitmap.
- *
- * Added CSP_FLAG_MODIFIED and CSP_FLAG_CHUNKED
- *
- * Added buffer_limit to struct configuration_spec
- *
- * Revision 1.33 2001/09/20 13:30:08 steudten
- *
- * Make freez() more secure in case of: if (exp) { free(z) ; a=*z }
- * Last case will set z to NULL in free(z) and thats bad..
- *
- * Revision 1.32 2001/09/16 23:02:51 jongfoster
- * Fixing warning
- *
- * Revision 1.31 2001/09/16 13:20:29 jongfoster

- * Revision 1.27 2001/08/05 16:06:20 jongfoster
- * Modifiying "struct map" so that there are now separate header and
- * "map_entry" structures. This means that functions which modify a
- * map no longer need to return a pointer to the modified map.
- * Also, it no longer reverses the order of the entries (which may be
- * important with some advanced template substitutions).
- *

- * list_shared.
- *
- * Revision 1.9 2001/05/31 17:32:31 oes
- *
- * - Enhanced domain part globbing with infix and prefix asterisk
- * matching and optional unanchored operation
- *
- * Revision 1.8 2001/05/29 20:09:15 joergs
- * HTTP_REDIRECT_TEMPLATE fixed.
- *
- * Revision 1.7 2001/05/29 09:50:24 jongfoster
- * Unified blocklist/imagelist/actionslist.
- * File format is still under discussion, but the internal changes
- * are (mostly) done.
- *
- * Also modified interceptor behaviour:
- * - We now intercept all URLs beginning with one of the following
- * prefixes (and *only* these prefixes):
- * * http://i.j.b/
- * * http://ijbswa.sf.net/config/
- * * http://ijbswa.sourceforge.net/config/
- * - New interceptors "home page" - go to http://i.j.b/ to see it.
- * - Internal changes so that intercepted and fast redirect pages
- * are not replaced with an image.
- * - Interceptors now have the option to send a binary page direct
- * to the client. (i.e. ijb-send-banner uses this)
- * - Implemented show-url-info interceptor. (Which is why I needed
- * the above interceptors changes - a typical URL is
- * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
- * The previous mechanism would not have intercepted that, and
- * if it had been intercepted then it then it would have replaced
- * it with an image.)
- *
- * Revision 1.6 2001/05/27 22:17:04 oes
- *
- * - re_process_buffer no longer writes the modified buffer
- * to the client, which was very ugly. It now returns the
- * buffer, which it is then written by chat.
- *
- * - content_length now adjusts the Content-Length: header
- * for modified documents rather than crunch()ing it.
- * (Length info in csp->content_length, which is 0 for
- * unmodified documents)
- *
- * - For this to work, sed() is called twice when filtering.
- *
- * Revision 1.5 2001/05/26 00:28:36 jongfoster
- * Automatic reloading of config file.
- * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
- * Most of the global variables have been moved to a new
- * struct configuration_spec, accessed through csp->config->globalname
- * Most of the globals remaining are used by the Win32 GUI.
- *
- * Revision 1.4 2001/05/22 18:46:04 oes
- *
- * - Enabled filtering banners by size rather than URL
- * by adding patterns that replace all standard banner
- * sizes with the "Junkbuster" gif to the re_filterfile
- *
- * - Enabled filtering WebBugs by providing a pattern
- * which kills all 1x1 images
- *
- * - Added support for PCRE_UNGREEDY behaviour to pcrs,
- * which is selected by the (nonstandard and therefore
- * capital) letter 'U' in the option string.
- * It causes the quantifiers to be ungreedy by default.
- * Appending a ? turns back to greedy (!).
- *
- * - Added a new interceptor ijb-send-banner, which
- * sends back the "Junkbuster" gif. Without imagelist or
- * MSIE detection support, or if tinygif = 1, or the
- * URL isn't recognized as an imageurl, a lame HTML
- * explanation is sent instead.
- *
- * - Added new feature, which permits blocking remote
- * script redirects and firing back a local redirect
- * to the browser.
- * The feature is conditionally compiled, i.e. it
- * can be disabled with --disable-fast-redirects,
- * plus it must be activated by a "fast-redirects"
- * line in the config file, has its own log level
- * and of course wants to be displayed by show-proxy-args
- * Note: Boy, all the #ifdefs in 1001 locations and
- * all the fumbling with configure.in and acconfig.h
- * were *way* more work than the feature itself :-(
- *
- * - Because a generic redirect template was needed for
- * this, tinygif = 3 now uses the same.
- *
- * - Moved GIFs, and other static HTTP response templates
- * to project.h
- *
- * - Some minor fixes
- *
- * - Removed some >400 CRs again (Jon, you really worked
- * a lot! ;-)
- *
- * Revision 1.3 2001/05/20 01:21:20 jongfoster
- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "actionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.
- *
- * Revision 1.2 2001/05/17 23:01:01 oes
- * - Cleaned CRLF's from the sources and related files
- *
- * Revision 1.1.1.1 2001/05/15 13:59:03 oes
- * Initial import of version 2.9.3 source tree
- *

- * 6 : ignore_leading = nonzero to ignore leading field

- *
- * Returns : -1 => Error: vec_len is too small to hold all the

- * >=0 => the number of fields put in `vec'.
- * On error, vec and str may still have been overwritten.

- *
- * Standardizing that struct http_request is used to represent a URL, and
- * struct url_spec is used to represent a URL pattern. (Before, URLs were
- * represented as seperate variables and a partially-filled-in url_spec).

- * Moving all our URL and URL pattern parsing code to the same file - it

- *
- * Providing a single, simple url_match(pattern,url) function - rather than

- * Renaming free_url to free_url_spec, since it frees a struct url_spec.

- * Providing parse_http_url() so that URLs can be parsed without faking a
- * HTTP request line for parse_http_request() or repeating the parsing
- * code (both of which were techniques that were actually in use).
- *
- * Standardizing that struct http_request is used to represent a URL, and
- * struct url_spec is used to represent a URL pattern. (Before, URLs were
- * represented as seperate variables and a partially-filled-in url_spec).

- * Revision 1.13 2001/07/19 19:15:14 haroon
- * - Added a FIXME for EditFile but didn't fix :-)
- *
- * Revision 1.12 2001/07/13 14:04:59 oes
- * Removed all #ifdef PCRS
- *
- * Revision 1.11 2001/06/07 23:08:12 jongfoster
- * Forward and ACL edit options removed.
- *
- * Revision 1.10 2001/05/31 21:37:11 jongfoster
- * GUI changes to rename "permissions file" to "actions file".
- *
- * Revision 1.9 2001/05/31 17:33:13 oes
- *
- * CRLF -> LF
- *
- * Revision 1.8 2001/05/29 09:50:24 jongfoster
- * Unified blocklist/imagelist/permissionslist.
- * File format is still under discussion, but the internal changes
- * are (mostly) done.
- *
- * Also modified interceptor behaviour:
- * - We now intercept all URLs beginning with one of the following
- * prefixes (and *only* these prefixes):
- * * http://i.j.b/
- * * http://ijbswa.sf.net/config/
- * * http://ijbswa.sourceforge.net/config/
- * - New interceptors "home page" - go to http://i.j.b/ to see it.
- * - Internal changes so that intercepted and fast redirect pages
- * are not replaced with an image.
- * - Interceptors now have the option to send a binary page direct
- * to the client. (i.e. ijb-send-banner uses this)
- * - Implemented show-url-info interceptor. (Which is why I needed
- * the above interceptors changes - a typical URL is
- * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
- * The previous mechanism would not have intercepted that, and
- * if it had been intercepted then it then it would have replaced
- * it with an image.)
- *
- * Revision 1.7 2001/05/26 01:26:34 jongfoster
- * New #define, WIN_GUI_EDIT, enables the (embryonic) Win32 GUI editor.
- * This #define cannot be set from ./configure - there's no point, it
- * doesn't work yet. See feature request # 425722
- *
- * Revision 1.6 2001/05/26 00:31:30 jongfoster
- * Fixing compiler warning about comparing signed/unsigned.
- *
- * Revision 1.5 2001/05/26 00:28:36 jongfoster
- * Automatic reloading of config file.
- * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
- * Most of the global variables have been moved to a new
- * struct configuration_spec, accessed through csp->config->globalname
- * Most of the globals remaining are used by the Win32 GUI.
- *
- * Revision 1.4 2001/05/22 18:56:28 oes
- * CRLF -> LF
- *
- * Revision 1.3 2001/05/20 15:07:54 jongfoster
- * File is now ignored if _WIN_CONSOLE is defined.
- *
- * Revision 1.2 2001/05/20 01:21:20 jongfoster
- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.
- *
- * Revision 1.1.1.1 2001/05/15 13:59:07 oes
- * Initial import of version 2.9.3 source tree
- *

- * Most of the globals remaining are used by the Win32 GUI.
- *
- * Revision 1.2 2001/05/20 01:21:20 jongfoster
- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.
- *
- * Revision 1.1.1.1 2001/05/15 13:59:08 oes
- * Initial import of version 2.9.3 source tree
