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.

(i.e. usually for logging, files, or memory allocation in + * itself or a called function.) + * - struct magic has been converted from an array to a single-ended linked + * list because it only grows one record at a time, it's only accessed + * sequentially, and the Apache API has no equivalent of realloc(). + * - Functions have been changed to get their parameters from the server + * configuration instead of globals. (It should be reentrant now but has + * not been tested in a threaded environment.) + * - Places where it used to print results to stdout now saves them in a + * list where they're used to set the MIME type in the Apache request + * record. + * - Command-line flags have been removed since they will never be used here. + * + * Ian Kluft <ikluft@cisco.com> + * Engineering Information Framework + * Central Engineering + * Cisco Systems, Inc. + * San Jose, CA, USA + * + * Initial installation July/August 1996 + * Misc bug fixes May 1997 + * Submission to Apache Software Foundation July 1997 + * + */ + +#include "apr.h" +#include "apr_strings.h" +#include "apr_lib.h" +#define APR_WANT_STRFUNC +#include "apr_want.h" + +#if APR_HAVE_UNISTD_H +#include <unistd.h> +#endif + +#include "ap_config.h" +#include "httpd.h" +#include "http_config.h" +#include "http_request.h" +#include "http_core.h" +#include "http_log.h" +#include "http_protocol.h" +#include "util_script.h" + +/* ### this isn't set by configure? does anybody set this? */ +#ifdef HAVE_UTIME_H +#include <utime.h> +#endif + +/* + * data structures and related constants + */ + +#define MODNAME "mod_mime_magic" +#define MIME_MAGIC_DEBUG 0 + +#define MIME_BINARY_UNKNOWN "application/octet-stream" +#define MIME_TEXT_UNKNOWN "text/plain" + +#define MAXMIMESTRING 256 + +/* HOWMANY must be at least 4096 to make gzip -dcq work */ +#define HOWMANY 4096 +/* SMALL_HOWMANY limits how much work we do to figure out text files */ +#define SMALL_HOWMANY 1024 +#define MAXDESC 50 /* max leng of text description */ +#define MAXstring 64 /* max leng of "string" types */ + +struct magic { + struct magic *next; /* link to next entry */ + int lineno; /* line number from magic file */ + + short flag; +#define INDIR 1 /* if '>(...)' appears, */ +#define UNSIGNED 2 /* comparison is unsigned */ + short cont_level; /* level of ">" */ + struct { + char type; /* byte short long */ + long offset; /* offset from indirection */ + } in; + long offset; /* offset to magic number */ + unsigned char reln; /* relation (0=eq, '>'=gt, etc) */ + char type; /* int, short, long or string. */ + char vallen; /* length of string value, if any */ +#define BYTE 1 +#define SHORT 2 +#define LONG 4 +#define STRING 5 +#define DATE 6 +#define BESHORT 7 +#define BELONG 8 +#define BEDATE 9 +#define LESHORT 10 +#define LELONG 11 +#define LEDATE 12 + union VALUETYPE { + unsigned char b; + unsigned short h; + unsigned long l; + char s[MAXstring]; + unsigned char hs[2]; /* 2 bytes of a fixed-endian "short" */ + unsigned char hl[4]; /* 2 bytes of a fixed-endian "long" */ + } value; /* either number or string */ + unsigned long mask; /* mask before comparison with value */ + char nospflag; /* suppress space character */ + + /* NOTE: this string is suspected of overrunning - find it! */ + char desc[MAXDESC]; /* description */ +}; + +/* + * data structures for tar file recognition + * -------------------------------------------------------------------------- + * Header file for public domain tar (tape archive) program. + * + * @(#)tar.h 1.20 86/10/29 Public Domain.

Essentially "everywhere" should include all possible + * httpds across all servers at a particular "site". We make some assumptions + * that if the site has a cluster of machines then their time is relatively + * synchronized. We also assume that the first address returned by a + * gethostbyname (gethostname()) is unique across all the machines at the + * "site". + * + * The root is assumed to absolutely uniquely identify this one child + * from all other currently running children on all servers (including + * this physical server if it is running multiple httpds) from each + * other. + * + * The stamp and counter are used to distinguish all hits for a + * particular root. The stamp is updated using r->request_time, + * saving cpu cycles. The counter is never reset, and is used to + * permit up to 64k requests in a single second by a single child. + * + * The 144-bits of unique_id_rec are encoded using the alphabet + * [A-Za-z0-9@-], resulting in 24 bytes of printable characters. That is then + * stuffed into the environment variable UNIQUE_ID so that it is available to + * other modules. The alphabet choice differs from normal base64 encoding + * [A-Za-z0-9+/] because + and / are special characters in URLs and we want to + * make it easy to use UNIQUE_ID in URLs. + * + * Note that UNIQUE_ID should be considered an opaque token by other + * applications. No attempt should be made to dissect its internal components. + * It is an abstraction that may change in the future as the needs of this + * module change. + * + * It is highly desirable that identifiers exist for "eternity". But future + * needs (such as much faster webservers, or moving to a + * multithreaded server) may dictate a need to change the contents of + * unique_id_rec. Such a future implementation should ensure that the first + * field is still a time_t stamp. By doing that, it is possible for a site to + * have a "flag second" in which they stop all of their old-format servers, + * wait one entire second, and then start all of their new-servers. This + * procedure will ensure that the new space of identifiers is completely unique + * from the old space. (Since the first four unencoded bytes always differ.) + * + * Note: previous implementations used 32-bits of IP address plus pid + * in place of the PRNG output in the "root" field. This was + * insufficient for IPv6-only hosts, required working DNS to determine + * a unique IP address (fragile), and needed a [0, 1) second sleep + * call at startup to avoid pid reuse.
