* Buffer overflow fixes from Drew Yao
|
||||
|
||||
2009-04-30 17:10 Christos Zoulas <christos@zoulas.com>
|
||||
|
||||
* Fix more cdf lossage. All the documents I have
|
||||
right now print the correct information.
|
||||
|
||||
2009-03-27 18:43 Christos Zoulas <christos@zoulas.com>
|
||||
|
||||
* don't print \012- separators in the same magic entry
|
||||
if it consists of multiple magic printing lines.

2009-03-18 16:50 Christos Zoulas <christos@zoulas.com>
|
||||
|
||||
* Allow escaping of relation characters, so that we can say \^[A-Z]
|
||||
and the ^ is not eaten as a relation char.
|
||||
|
||||
* Fix troff and fortran to their previous glory using
|
||||
regex. This was broken since their removel from ascmagic.

|
||||
|
||||
2009-02-23 15:45 Christos Zoulas <christos@zoulas.com>
|
||||
|

* make the cdf code use the buffer first if available,
|
||||
and then the fd code.
|
||||
|
||||
2009-02-13 13:45 Christos Zoulas <christos@zoulas.com>

|
||||
|
||||
* sanitize cdf document strings

This is Release 5.x of Ian Darwin's (copyright but distributable)

file(1) command. This version is the standard "file" command for Linux,
|

*BSD, and other systems. (See "patchlevel.h" for the exact release number).
|
||||
|
||||
The major changes for 5.x are CDF file parsing, indirect magic, and
|
||||
overhaul in mime and ascii encoding handling.
|
||||
|
||||
The major feature of 4.x is the refactoring of the code into a library,
|
||||
and the re-write of the file command in terms of that library. The library
|
||||
itself, libmagic can be used by 3rd party programs that wish to identify
