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

	* Fix another integer overflow (Colin Percival)

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

	* make sure that all of struct magic_set is initialized appropriately
	  (Brett)

2007-03-25 17:44 Christos Zoulas <christos@zoulas.com>

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

	* compilation failed with COMPILE_ONLY and ENABLE_CONDITIONALS
	  (Peter Avalos)

2007-03-15 10:51 Christos Zoulas <christos@zoulas.com>

	* fix fortran and nroff reversed tests (Dmitry V. Levin)
	
	* fix exclude option (Dmitry V. Levin)

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

	* fix integer underflow in file_printf which can lead to
	  to exploitable heap overflow (Jean-Sebastien Guay-Lero)

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

	* make socket/pipe reading more robust

2007-01-25 16:01 Christos Zoulas <christos@zoulas.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.

2007-01-16 14:54 Anon Ymous <do@not.spam.me>

	* fix a puts()/putc() usage goof in file.c

	* make file.c compile with gcc warnings and pass lint

2006-12-11 16:49 Christos Zoulas <christos@zoulas.com>

	* fix byteswapping issue

	* report the number of bytes we tried to
	  allocate when allocation fails

	* add a few missed cases in the strength routine

2006-12-08 16:32 Christos Zoulas <christos@zoulas.com>

	* store and print the line number of the magic
	  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@zoulas.com>
	
	* Don't store the current offset in the magic
	  struct, because it needs to be restored and

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

2004-11-24 12:39  Christos Zoulas  <christos@zoulas.com>
