Thanks to Matthew Fischer * for spotting. * * Revision 1.29.2.1 2003/12/17 16:33:28 oes * Added prototype of new function cgi_redirect * * Revision 1.29 2002/05/19 11:33:21 jongfoster * If a CGI error was not handled, and propogated back to * dispatch_known_cgi(), then it was assumed to be "out of memory". * This gave a very misleading error message. * * Now other errors will cause a simple message giving the error * number and asking the user to report a bug. * * Bug report: * http://sourceforge.net/tracker/index.php?func=detail * &aid=557905&group_id=11118&atid=111118 * * Revision 1.28 2002/04/26 12:54:03 oes * New function add_help_link * * Revision 1.27 2002/04/24 02:16:51 oes * Moved get_char_param, get_string_param and get_number_param here from cgiedit.c * * Revision 1.26 2002/04/10 13:38:35 oes * load_template signature changed * * Revision 1.25 2002/04/08 20:50:25 swa * fixed JB spelling * * Revision 1.24 2002/03/26 22:29:54 swa * we have a new homepage! * * Revision 1.23 2002/03/24 16:18:15 jongfoster * Removing old logo * * Revision 1.22 2002/03/24 13:25:43 swa * name change related issues * * Revision 1.21 2002/03/07 03:48:38 oes * - 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 1.20 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 * 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 1.16 2001/09/16 17:08:54 jongfoster * Moving simple CGI functions from cgi.c to new file cgisimple.c * * Revision 1.15 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 1.14 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 1.13 2001/09/16 11:00:10 jongfoster * New function alloc_http_response, for symmetry with free_http_response * * Revision 1.12 2001/09/13 23:31:25 jongfoster * Moving image data to cgi.c rather than cgi.h. * * 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 * Adding prototype for map_conditional * * Revision 1.8 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 2001/07/29 18:43:08 jongfoster * Changing #ifdef _FILENAME_H to FILENAME_H_INCLUDED, to conform to * 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. * - Removed HTTP/HTML snipplets * - Removed logentry from cancelled commit * * Revision 1.4 2001/06/09 10:50:58 jongfoster * Changing "show URL info" handler to new style. * Adding "extern" to some function prototypes. * * Revision 1.3 2001/06/03 19:12:16 oes * introduced new cgi handling * * No revisions before 1.3 * **********************************************************************/ #include "project.h" #ifdef __cplusplus extern "C" { #endif /* * Main dispatch function */ extern struct http_response *dispatch_cgi(struct client_state *csp); /* Not exactly a CGI */ extern struct http_response * error_response(struct client_state *csp, const char *templatename, int err); /* * CGI support functions */ extern struct http_response * alloc_http_response(void); extern void free_http_response(struct http_response *rsp); extern struct http_response *finish_http_response(struct http_response *rsp); extern struct map * default_exports(const struct client_state *csp, const char *caller); extern jb_err map_block_killer (struct map *exports, const char *name); extern jb_err map_block_keep (struct map *exports, const char *name); extern jb_err map_conditional (struct map *exports, const char *name, int choose_first); extern jb_err template_load(struct client_state *csp, char ** template_ptr, const char *templatename, int recursive); extern jb_err template_fill(char ** template_ptr, const struct map *exports); extern jb_err template_fill_for_cgi(struct client_state *csp, const char *templatename, struct map *exports, struct http_response *rsp); extern void cgi_init_error_messages(void); extern struct http_response *cgi_error_memory(void); extern jb_err cgi_redirect (struct http_response * rsp, const char *target); extern jb_err cgi_error_no_template(struct client_state *csp, struct http_response *rsp, const char *template_name); extern jb_err cgi_error_bad_param(struct client_state *csp, struct http_response *rsp); extern jb_err cgi_error_disabled(struct client_state *csp, struct http_response *rsp); extern jb_err cgi_error_unknown(struct client_state *csp, struct http_response *rsp, jb_err error_to_report); extern jb_err get_number_param(struct client_state *csp, const struct map *parameters, char *name, unsigned *pvalue); extern jb_err get_string_param(const struct map *parameters, const char *param_name, const char **pparam); extern char get_char_param(const struct map *parameters, const char *param_name); /* * Text generators */ extern void get_http_time(int time_offset, char * buf); extern char *add_help_link(const char *item, struct configuration_spec *config); extern char *make_menu(const char *self, const unsigned feature_flags); extern char *dump_map(const struct map *the_map); /* * Ad replacement images */ extern const char image_pattern_data[]; extern const size_t image_pattern_length; extern const char image_blank_data[]; extern const size_t image_blank_length; /* Revision control strings from this header and associated .c file */ extern const char cgi_rcs[]; extern const char cgi_h_rcs[]; #ifdef __cplusplus } /* extern "C" */ #endif #endif /* ndef CGI_H_INCLUDED */ /* Local Variables: tab-width: 3 end: */
