        * The following fixes resulted from Thomas Jarosch's fuzzing
          tests that revealed severe performance issues on pathological
          input:
            - limit number of elf program and sections processing
            - abort elf note processing quickly
            - reduce the number of recursion levels from 20 to 10
            - preserve error messages in indirect magic handling

        This is tracked as CVE-2014-8116 and CVE-2014-8117

        * Enforce limit of 8K on regex searches that have no limits
        * Allow the l modifier for regex to mean line count. Default
          to byte count. If line count is specified, assume a max
          of 80 characters per line to limit the byte count.
        * Don't allow conversions to be used for dates, allowing
          the mask field to be used as an offset.

2014-05-30  12:51  Christos Zoulas <christos@zoulas.com>

        * Make the range operator limit the length of the
          regex search.

2014-04-30  17:39  Christos Zoulas <christos@zoulas.com>

        * Fix integer formats: We don't specify 'l' or
          'h' and 'hh' specifiers anymore, only 'll' for
          quads and nothing for the rest. This is so that
          magic writing is simpler.

2014-04-01  15:25  Christos Zoulas <christos@zoulas.com>

        * add size_t overflow check for magic file size

2014-02-27  16:01  Christos Zoulas <christos@zoulas.com>

        * experimental support for matching with CFD CLSID

2014-02-18  13:04  Kimmo Suominen (kimmo@suominen.com)

        * Cache old LC_CTYPE locale before setting it to "C", so
          we can use it to restore LC_CTYPE instead of asking
          setlocale() to scan the environment variables.

2014-02-12  18:21  Christos Zoulas <christos@zoulas.com>

        * Count recursion levels through indirect magic

          and exit.

2014-01-08  17:20  Christos Zoulas <christos@zoulas.com>

        * mime printing could print results from multiple magic entries
          if there were multiple matches.
        * in some cases overflow was not detected when computing offsets
          in softmagic.

2013-12-05  12:00  Christos Zoulas <christos@zoulas.com>

        * use strcasestr() to for cdf strings
        * reset to the "C" locale while doing regex operations, or case
          insensitive comparisons; this is provisional

2013-11-19  20:10  Christos Zoulas <christos@zoulas.com>

        * always leave magic file loaded, don't unload for magic_check, etc.
        * fix default encoding to binary instead of unknown which broke recently
        * handle empty and one byte files, less specially so that
          --mime-encoding does not break completely.
                `
2013-11-06  14:40  Christos Zoulas <christos@zoulas.com>

        * fix erroneous non-zero exit code from non-existant file and message

2013-10-29  14:25  Christos Zoulas <christos@zoulas.com>

        * add CDF MSI file detection (Guy Helmer)

2013-09-03  11:56  Christos Zoulas <christos@zoulas.com>

        * Don't mix errors and regular output if there was an error
        * in magic_descriptor() don't close the file and try to restore
          its position

2013-05-30  17:25  Christos Zoulas <christos@zoulas.com>

        * Don't treat magic as an error if offset was past EOF (Christoph Biedl)

2013-05-28  17:25  Christos Zoulas <christos@zoulas.com>
        
        * Fix spacing issues in softmagic and elf (Jan Kaluza)

2013-05-02  18:00  Christos Zoulas <christos@zoulas.com>

        * Fix segmentation fault with multiple magic_load commands.

2013-04-22  11:20  Christos Zoulas <christos@zoulas.com>

        * The way "default" was implemented was not very useful
          because the "if something was printed at that level"
          was not easily controlled by the user, and the format
          was bound to a string which is too restrictive. Add
          a "clear" for that level keyword and make "default"
          void. This way one can do:

                >>13    clear   x
                >>13    lelong  1       foo
                >>13    lelong  2       bar
                >>13    default x
                >>>13   lelong  x       unknown %x

2013-03-25  13:20  Christos Zoulas <christos@zoulas.com>

        * disallow strength setting in "name" entries

2013-03-06  21:24  Christos Zoulas <christos@zoulas.com>

        * fix recursive magic separator printing

2013-02-26  19:28  Christos Zoulas <christos@zoulas.com>

        * limit recursion level for mget
        * fix pread() related breakage in cdf
        * handle offsets properly in recursive "use"

2013-02-18  10:39  Christos Zoulas <christos@zoulas.com>

        * add elf reading of debug info to determine if file is stripped
          (Jan Kaluza)
        * use pread()

2013-01-25  18:05  Christos Zoulas <christos@zoulas.com>

        * change mime description size from 64 to 80 to accommodate OOXML.

2013-01-11  14:50  Christos Zoulas <christos@zoulas.com>

        * Warn about inconsistent continuation levels.
        * Change fsmagic to add a space after it prints.

2013-01-10  21:00  Christos Zoulas <christos@zoulas.com>

        * Make getline public so that file can link against it.
          Perhaps it is better to rename it, or hide it differently.
          Fixes builds on platforms that do not provide it.
          
2013-01-07  16:30  Christos Zoulas <christos@zoulas.com>

          what long, int, short, etc is (Guy Harris)

2013-01-06  11:20  Christos Zoulas <christos@zoulas.com>

        * add magic_version function and constant
        * Redo memory allocation and de-allocation.
          (prevents double frees on non mmap platforms)
        * Fix bug with name/use having to do with passing
          found state from the parent to the child and back.

2012-12-19   8:47  Christos Zoulas <christos@zoulas.com>

        * Only print elf capabilities for archs we know (Jan Kaluza)

2012-10-30  19:14  Christos Zoulas <christos@zoulas.com>

        * use ctime_r, asctime_r

2012-04-06  17:18  Christos Zoulas <christos@zoulas.com>

        * Fixes for indirect offsets to handle apple disk formats

2012-04-03  18:26  Christos Zoulas <christos@zoulas.com>

        * Add windows date field types
        * More info for windows shortcuts (incomplete)

        * Fix CDF parsing issues found by CERT's fuzzing tool (Will Dormann)

2011-12-15  12:17  Chris Metcalf <cmetcalf@tilera.com>

2011-12-16  16:33  Reuben Thomas <rrt@sc3d.org>

        * Add magic for /usr/bin/env Perl scripts
        * Weaken generic script magic to avoid clashing with
        language-specific magic.

2011-12-08  13:37  Reuben Thomas <rrt@sc3d.org>

        * Simplify if (p) free(p) to free(p).

2011-12-08  13:07  Reuben Thomas <rrt@sc3d.org>

        * Remove hardwired token finding (names.h), turning it into soft
        magic. Patterns are either anchored regexs or search/8192. English
        language detection and PL/1 detection have been removed as they
        were too fragile. -e tokens is still accepted for backwards
        compatibility.
        * Move 3ds patterns (which are commented out anyway) into autodesk
        (they were, oddly, in c-lang).

2011-12-06  00:16  Reuben Thomas <rrt@sc3d.org>

        * Tweak strength of generic hash-bang detectors to be less than
        specific ones.
        * Make an inconsistent description of Python scripts consistent.

2011-12-05  23:58  Reuben Thomas <rrt@sc3d.org>

        * Fix minor error in file(1).

2011-11-05  00:00  Reuben Thomas <rrt@sc3d.org>

        * Fix issue #150 (I hope).

2011-09-22  12:57  Christos Zoulas <christos@zoulas.com>

        * Python3 binding fixes from Kelly Anderson

2011-09-20  11:32  Christos Zoulas <christos@zoulas.com>

        * If a string type magic entry is marked as text or binary
          only match text files against text entries and binary
          files against binary entries.

2011-09-01  12:12  Christos Zoulas <christos@zoulas.com>

        * Don't wait for any subprocess, just the one we forked.

2011-08-26  16:40  Christos Zoulas <christos@zoulas.com>

        * If the application name is not set in a cdf file, try to see
          if it has a directory with the application name on it.

2011-08-17  14:32  Christos Zoulas <christos@zoulas.com>

        * Fix ELF lseek(2) madness. Inspired by PR/134 by Jan Kaluza

2011-08-14  09:03  Christos Zoulas <christos@zoulas.com>

        * Don't use variable string formats.

2011-07-12  12:32  Reuben Thomas <rrt@sc3d.org>

        * Fix detection of Zip files (Mantis #128).
        * Make some minor improvements to file(1).
        * Rename MIME types for filesystem objects for consistency with
          xdg-utils. Typically this means that application/x-foo becomes
          inode/foo, but some names also change slightly, e.g.
          application/x-character-device becomes inode/chardevice.

2011-05-10  20:57  Christos Zoulas <christos@zoulas.com>

        * fix mingw compilation (Abradoks)

2011-05-10  20:57  Christos Zoulas <christos@zoulas.com>

        * remove patchlevel.h
        * Fix read past allocated memory caused by double-incrementing
          a pointer in a loop (reported by Roberto Maar)

2011-03-30  15:45  Christos Zoulas <christos@zoulas.com>

        * Fix cdf string buffer setting (Sven Anders)

2011-03-20  16:35  Christos Zoulas <christos@zoulas.com>

          path and file buffers.

2011-03-15  18:15  Christos Zoulas <christos@zoulas.com>

        * binary tests on magic entries with masks could spuriously
          get converted to ascii.

        * Improve file.man (remove BUGS, present email addresses consistently).

2011-03-07  19:38  Christos Zoulas <christos@zoulas.com>

        * add lrzip support (from Ville Skytta)

2011-02-10  16:36  Christos Zoulas <christos@zoulas.com>

        * fix CDF bounds checking (Guy Helmer)

2011-02-10  12:03  Christos Zoulas <christos@zoulas.com>

        * add cdf_ctime() that prints a meaningful error when time cannot
          be converted.

        * help and version output to stdout.

        * When matching softmagic for ascii files, don't just print
          the softmagic classification, keep going and print the
          text classification too. This fixes broken troff files when
          we moved them from keyword recognition to softmagic
          (they stopped printing "with CRLF" etc.)
          Reported by Doug McIlroy.

          driven routine.  This avoids maintaining multiple lists in
          file.h.

        * Add an optional conditional field (ust before the type field).
          This code is wrapped in "#ifdef ENABLE_CONDITIONALS" as it is
          likely to go away.

        * Fix an initialization bug in check_mem().

2007-01-16 14:58 Anon Ymous <do@not.spam.me>

        * Add a "default" type to print a message if nothing previously
          matched at that level or since the last default at that
          level.  This is useful for setting up switch-like statements.
          It can also be used to do if/else constructions without a
          redundant second test.

        * Fix the "x" special case test so that one can test for that
          string with "=x".

        * Allow "search" to search the entire buffer if the "/N"
          search count is missing.

        * Make "regex" work!  It now starts its search at the
          specified offset and takes an (optional) "/N" line count to
          specify the search range; otherwise it searches to the end
          of the file.  The match is now grabbed correctly for format
          strings and the offset set to the end of the match.

        * Add a "/s" flag to "regex" and "search" to set the offset to
          the start of the match.  By default the offset is set to the
          end of the match, as it is with other tests.  This is mostly
          useful for "regex".

        * Make "search", "string" and "pstring" use the same
          file_strncmp() routine so that they support the same flags;
          "bestring16" and "lestring16" call the same routine, but
          with flags = 0.  Also add a "/C" flag (in analogy to "/c")
          to ignore the case on uppercase (lowercase) characters in
          the test string.

        * Strict adherence to C style string escapes.  A warnings are
          printed when compiling.  Note: previously "\a" was
          incorrectly translated to 'a' instead of an <alert> (i.e.,
          BELL, typically 0x07).

        * Make this compile with "-Wall -Wextra" and all the warning
          flags used with WARNS=4 in the NetBSD source.  Also make it
          pass lint.

        * Many "cleanups" and hopefully not too many new bugs!

2007-01-16 14:56 Anon Ymous <do@not.spam.me>

        * make several more files compile with gcc warnings

2005-01-12 00:00  Stepan Kasal  <kasal@ucw.cz>

        * src/ascmagic.c (file_ascmagic): Fix three bugs about text files:
          If a CRLF text file happens to have CR at offset HOWMANY - 1
          (currently 0xffff), it should not be counted as CR line
          terminator.
          If a line has length exactly MAXLINELEN, it should not yet be
          treated as a ``very long line'', as MAXLINELEN is ``longest sane
          line length''.
          With CRLF, the line length was not computed correctly, and even
          lines of length MAXLINELEN - 1 were treated as ``very long''.

          have access to it. <christos@astron.com>
