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

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>

	* Fix detection of Zip files (Mantis #128).
	* Make some minor improvements to file(1).
	* Rename MIME types for filesystem objects for consistency with

	* 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.)

	  This work was done by Reuben Thomas

2007-05-24 10:00 Christos Zoulas <christos@astron.com>

	* Fix another integer overflow (Colin Percival)

2007-03-26 13:58 Christos Zoulas <christos@astron.com>

	* reset left bytes in the buffer (Dmitry V. Levin)

	* compilation failed with COMPILE_ONLY and ENABLE_CONDITIONALS

2007-02-08 17:30 Christos Zoulas <christos@astron.com>

	  to exploitable heap overflow (Jean-Sebastien Guay-Lero)

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>

	  struct, because it needs to be restored and
	  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.

	* 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''.

	* 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
	  the file descriptor to read as much as it wants if we
	  have access to it. <christos@astron.com>
