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 * Parsing functions now handle out-of-memory gracefully by returning * an error code. * * Revision 1.19 2002/01/17 21:03:47 jongfoster * Moving all our URL and URL pattern parsing code to urlmatch.c. * * Revision 1.18 2001/10/26 17:40:23 oes * Introduced get_header_value() * Removed client_accept() * * Revision 1.17 2001/10/13 12:47:32 joergs * Removed client_host, added client_host_adder * * Revision 1.16 2001/10/07 18:50:16 oes * Added server_content_encoding, renamed server_transfer_encoding * * Revision 1.15 2001/10/07 18:01:55 oes * Changed server_http11 to server_http * * Revision 1.14 2001/10/07 15:45:48 oes * added client_accept_encoding, client_te, client_accept_encoding_adder * * renamed content_type and content_length * * fixed client_host and strclean prototypes * * Revision 1.13 2001/09/29 12:56:03 joergs * 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 * Changing #ifdef _FILENAME_H to FILENAME_H_INCLUDED, to conform to * ANSI C rules. * * Revision 1.8 2001/07/13 14:01:54 oes * Removed all #ifdef PCRS * * Revision 1.7 2001/06/29 13:32:14 oes * Removed logentry from cancelled commit * * Revision 1.6 2001/06/03 19:12:38 oes * deleted const struct interceptors * * Revision 1.5 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 1.4 2001/05/27 13:19:06 oes * Patched Joergs solution for the content-length in. * * Revision 1.3 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 1.2 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 13:59:01 oes * Initial import of version 2.9.3 source tree * * *********************************************************************/ #include "project.h" #ifdef __cplusplus extern "C" { #endif extern const struct parsers client_patterns[]; extern const struct parsers server_patterns[]; extern const struct parsers server_patterns_light[]; extern const add_header_func_ptr add_client_headers[]; extern const add_header_func_ptr add_server_headers[]; extern int flush_socket(jb_socket fd, struct iob *iob); extern jb_err add_to_iob(struct client_state *csp, char *buf, int n); extern jb_err decompress_iob(struct client_state *csp); extern char *get_header(struct client_state *csp); extern char *get_header_value(const struct list *header_list, const char *header_name); extern jb_err sed(const struct parsers pats[], const add_header_func_ptr more_headers[], struct client_state *csp); extern void get_http_time(int time_offset, char *buf, size_t buffer_size); extern jb_err get_destination_from_headers(const struct list *headers, struct http_request *http); #ifdef FEATURE_FORCE_LOAD extern int strclean(const char *string, const char *substring); #endif /* def FEATURE_FORCE_LOAD */ /* Revision control strings from this header and associated .c file */ extern const char parsers_rcs[]; extern const char parsers_h_rcs[]; extern int debug; #ifdef __cplusplus } /* extern "C" */ #endif #endif /* ndef PARSERS_H_INCLUDED */ /* Local Variables: tab-width: 3 end: */
