	  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.

	* PR/351: Fix compilation of empty files 

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>

	* PR/341: Jan Kaluza, fix memory leak

	* 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

2014-02-11  10:40  Christos Zoulas <christos@zoulas.com>

	* Prevent infinite recursion on files with indirect offsets of 0

2014-01-30  21:00  Christos Zoulas <christos@zoulas.com>

	  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>

	* 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>

	* 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>

	* Add SuS d{,1,2,4,8}, u{,1,2,4,8} and document
	  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>

	  inside mach-o files.

2012-09-06  10:40  Christos Zoulas <christos@zoulas.com>

	* make --version exit 0 (Matthew Schultz)
	* add string/T (Jan Kaluza)

2012-08-09  2:15  Christos Zoulas <christos@zoulas.com>

	* add z and t modifiers for our own vasprintf
	* search for $HOME/.magic.mgc if it is there first
	* fix reads from a pipe, and preserve errno

2012-05-15  13:12  Christos Zoulas <christos@zoulas.com>

	* 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

	  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.

	* 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>

	  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>

	* Eliminate MAXPATHLEN and use dynamic allocation for
	  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.

2011-03-12  18:06  Reuben Thomas <rrt@sc3d.org>

	* 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>

	  be converted.

2011-02-02  20:40  Christos Zoulas <christos@zoulas.com>

	* 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.

2011-01-16  19:31  Reuben Thomas <rrt@sc3d.org>

	* Fix two potential buffer overruns in apprentice_list.

2011-01-14  22:33  Reuben Thomas <rrt@sc3d.org>

	  update).

2011-01-04  18:43  Reuben Thomas <rrt@sc3d.org>

	* magic/Makefile.am: make it easier to recover from magic build failures.
	* Fix pstring length specifier parsing to avoid generating invalid
	  magic files.
	* Add pstring length "J" (for "JPEG") to specify that the length
	  include itself.
	* Fix JPEG comment parsing at last using pstring/HJ!
	* Ignore section 5 man pages in doc/.cvsignore.

2010-12-22  13:12  Christos Zoulas <christos@zoulas.com>

	  string as printf format).

2010-07-21  12:20  Christos Zoulas <christos@zoulas.com>

	* MINGW32 portability from LRN

	* Don't warn about escaping magic regex chars when we are in a regex.

	  https://bugzilla.redhat.com/show_bug.cgi?id=533245

2010-01-22  15:45  Christos Zoulas <christos@zoulas.com>

	* print proper mime for crystal reports file

	* print the last summary information of a cdf document, not the
	  first so that nested documents print the right info

2010-01-16  18:42  Charles Longeau <chl@tuxfamily.org>

	* bring back some fixes from OpenBSD:
		- make gcc2 builds file
		- fix typos in a magic file comment

2009-11-17  18:35  Christos Zoulas <christos@zoulas.com>

2007-02-05 11:35 Christos Zoulas <christos@astron.com>

	* make socket/pipe reading more robust

2007-01-25 16:01 Christos Zoulas <christos@astron.com>

	* Centralize all the tests in file_buffer.

	* Add exclude flag.

2007-01-18 05:29 Anon Ymous <do@not.spam.me>

	* Move the "type" detection code from parse() into its own table
	  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.

2007-01-16 23:24 Anon Ymous <do@not.spam.me>

	* 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
	  on and also make them pass lint.

	  entry for debugging.

	* if the magic entry did not print anything,
	  don't treat it as a match

	* change the magic strength algorithm to take
	  into account the relationship op.

	* fix a bug in search where we could accidentally
	  return a match.

	* propagate the error return from match to
	  file_softmagic.

2006-11-25 13:35 Christos Zoulas <christos@astron.com>

	  it was not done properly all the time. Bug
	  found by: Arkadiusz Miskiewicz

	* Fix problem in the '\0' separator; and don't
	  print it as an additional separator; print
	  it as the only separator.

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''.

2004-12-07 14:15  Christos Zoulas  <christos@astron.com>

	* bzip2 needs a lot of input buffer space on some files
	  before it can begin uncompressing. This makes file -z
	  fail on some bz2 files. Fix it by giving it a copy of
