Previous versions of the module defined behaviour - * on a per-server basis. The upshot is that you'll need to revisit your - * configuration files in order to make use of the new module. - * *** - * - * Emulate the CERN HTTPD Meta file semantics. Meta files are HTTP - * headers that can be output in addition to the normal range of - * headers for each file accessed. They appear rather like the Apache - * .asis files, and are able to provide a crude way of influencing - * the Expires: header, as well as providing other curiosities. - * There are many ways to manage meta information, this one was - * chosen because there is already a large number of CERN users - * who can exploit this module. It should be noted that there are probably - * more sensitive ways of managing the Expires: header specifically. - * - * The module obeys the following directives, which can appear - * in the server's .conf files and in .htaccess files. - * - * MetaFiles <on|off> - * - * turns on|off meta file processing for any directory. - * Default value is off - * - * # turn on MetaFiles in this directory - * MetaFiles on - * - * MetaDir <directory name> - * - * specifies the name of the directory in which Apache can find - * meta information files. The directory is usually a 'hidden' - * subdirectory of the directory that contains the file being - * accessed. eg: - * - * # .meta files are in the *same* directory as the - * # file being accessed - * MetaDir . - * - * the default is to look in a '.web' subdirectory. This is the - * same as for CERN 3.+ webservers and behaviour is the same as - * for the directive: - * - * MetaDir .web - * - * MetaSuffix <meta file suffix> - * - * specifies the file name suffix for the file containing the - * meta information. eg: - * - * # our meta files are suffixed with '.cern_meta' - * MetaSuffix .cern_meta - * - * the default is to look for files with the suffix '.meta'. This - * behaviour is the same as for the directive: - * - * MetaSuffix .meta - * - * When accessing the file - * - * DOCUMENT_ROOT/somedir/index.html - * - * this module will look for the file - * - * DOCUMENT_ROOT/somedir/.web/index.html.meta - * - * and will use its contents to generate additional MIME header - * information. - * - * For more information on the CERN Meta file semantics see: - * - * http://www.w3.org/hypertext/WWW/Daemon/User/Config/General.html#MetaDir - * - * Change-log: - * 29.Jan.96 pfopen/pfclose instead of fopen/fclose - * DECLINE when real file not found, we may be checking each - * of the index.html/index.shtml/index.htm variants and don't - * need to report missing ones as spurious errors. - * 31.Jan.96 log_error reports about a malformed .meta file, rather - * than a script error. - * 20.Jun.96 MetaFiles <on|off> default off, added, so that module - * can be configured per-directory. Prior to this the module - * was running for each request anywhere on the server, naughty.. - * 29.Jun.96 All directives made per-directory. - */ - -#include "apr.h" -#include "apr_strings.h" - -#define APR_WANT_STRFUNC -#include "apr_want.h" - -#if APR_HAVE_SYS_TYPES_H -#include <sys/types.h> -#endif - -#include "ap_config.h" -#include "httpd.h" -#include "http_config.h" -#include "util_script.h" -#include "http_log.h" -#include "http_request.h" -#include "http_protocol.h" -#include "apr_lib.h" - -#define DIR_CMD_PERMS OR_INDEXES - -#define DEFAULT_METADIR ".web" -#define DEFAULT_METASUFFIX ".meta" -#define DEFAULT_METAFILES 0 - -module AP_MODULE_DECLARE_DATA cern_meta_module; - -typedef struct { - const char *metadir; - const char *metasuffix; - int metafiles; -} cern_meta_dir_config; - -static void *create_cern_meta_dir_config(apr_pool_t *p, char *dummy) -{ - cern_meta_dir_config *new = - (cern_meta_dir_config *) apr_palloc(p, sizeof(cern_meta_dir_config)); - - new->metadir = NULL; - new->metasuffix = NULL; - new->metafiles = DEFAULT_METAFILES; - - return new; -} - -static void *merge_cern_meta_dir_configs(apr_pool_t *p, void *basev, void *addv) -{ - cern_meta_dir_config *base = (cern_meta_dir_config *) basev; - cern_meta_dir_config *add = (cern_meta_dir_config *) addv; - cern_meta_dir_config *new = - (cern_meta_dir_config *) apr_palloc(p, sizeof(cern_meta_dir_config)); - - new->metadir = add->metadir ? add->metadir : base->metadir; - new->metasuffix = add->metasuffix ? add->metasuffix : base->metasuffix; - new->metafiles = add->metafiles; - - return new; -} - -static const char *set_metadir(cmd_parms *parms, void *in_dconf, const char *arg) -{ - cern_meta_dir_config *dconf = in_dconf; - - dconf->metadir = arg; - return NULL; -} - -static const char *set_metasuffix(cmd_parms *parms, void *in_dconf, const char *arg) -{ - cern_meta_dir_config *dconf = in_dconf; - - dconf->metasuffix = arg; - return NULL; -} - -static const char *set_metafiles(cmd_parms *parms, void *in_dconf, int arg) -{ - cern_meta_dir_config *dconf = in_dconf; - - dconf->metafiles = arg; - return NULL; -} - - -static const command_rec cern_meta_cmds[] = -{ - AP_INIT_FLAG("MetaFiles", set_metafiles, NULL, DIR_CMD_PERMS, - "Limited to 'on' or 'off'"), - AP_INIT_TAKE1("MetaDir", set_metadir, NULL, DIR_CMD_PERMS, - "the name of the directory containing meta files"), - AP_INIT_TAKE1("MetaSuffix", set_metasuffix, NULL, DIR_CMD_PERMS, - "the filename suffix for meta files"), - {NULL} -}; - -/* XXX: this is very similar to ap_scan_script_header_err_core... - * are the differences deliberate, or just a result of bit rot? - */ -static int scan_meta_file(request_rec *r, apr_file_t *f) -{ - char w[MAX_STRING_LEN]; - char *l; - int p; - apr_table_t *tmp_headers; - - tmp_headers = apr_table_make(r->pool, 5); - while (apr_file_gets(w, MAX_STRING_LEN - 1, f) == APR_SUCCESS) { - - /* Delete terminal (CR?)LF */ - - p = strlen(w); - if (p > 0 && w[p - 1] == '\n') { - if (p > 1 && w[p - 2] == '\015') - w[p - 2] = '\0'; - else - w[p - 1] = '\0'; - } - - if (w[0] == '\0') { - return OK; - } - - /* if we see a bogus header don't ignore it.
