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 * * *********************************************************************/ #ifdef __cplusplus extern "C" { #endif /* Structures taken from project.h */ struct client_state; struct file_list; struct configuration_spec; struct url_spec; extern void sweep(void); extern char *read_config_line(char *buf, size_t buflen, FILE *fp, unsigned long *linenum); extern int check_file_changed(const struct file_list * current, const char * filename, struct file_list ** newfl); extern jb_err edit_read_line(FILE *fp, char **raw_out, char **prefix_out, char **data_out, int *newline, unsigned long *line_number); extern jb_err simple_read_line(FILE *fp, char **dest, int *newline); /* * Various types of newlines that a file may contain. */ #define NEWLINE_UNKNOWN 0 /* Newline convention in file is unknown */ #define NEWLINE_UNIX 1 /* Newline convention in file is '\n' (ASCII 10) */ #define NEWLINE_DOS 2 /* Newline convention in file is '\r\n' (ASCII 13,10) */ #define NEWLINE_MAC 3 /* Newline convention in file is '\r' (ASCII 13) */ /* * Types of newlines that a file may contain, as strings.
