Subject:	ANNOUNCE: DJGPP port of bzip2 1.0.8 uploaded.
Reply-To:	djgpp AT delorie DOT com

This is a port of bzip2 1.0.8 to MSDOS/DJGPP.

   bzip2 is a compressor/decompressor program with generally considerably better
   compression rate than that achieved by more conventional LZ77/LZ78-based
   compressors.
   The command-line options are deliberately very similar to those of GNU gzip,
   but they are not identical.


   DJGPP specific changes.
   =======================


   - The source archives that have been used to create this port can be
     downloaded as:
       ftp://sourceware.org/pub/bzip2/bzip2-1.0.8.tar.gz

   - There are no user visible DJGPP specific changes compared with the
     previous version.  If you are familiar with the previous version 1.0.6,
     you will be familiar with this one.

   - The port has been tested by using it.  I have used them only on WinXP,
     Win2K, Win98SE, MS-DOS 7.10 and MS-DOS 6.22.  It has worked flawlessly.
     I do not konw if this will ever be the case on FreeDOS.  I have never
     used/tested them in that environment.

   - The port has been configured and compiled on MS-DOS 6.22, MS-DOS 7.10,
     Win98SE and WinXP SP3.  There is no guarantee that this may be possible
     with any other DOS-like OS.  Due to the use of long file names it will
     not be possible to configure and compile without LFN support.  The port
     has been compiled using gcc346 and bnu234b.

   As usual, all djgpp specific files (diffs, README files, etc.) are stored
   in the "djgpp" directory.  The sources do not need to be configured and
   must be build in the top source directory.

   For further information about bzip2 please read the info docs and NEWS file.



   Here is an extract of the ChangeLog file showing the user visible changes
   from the last port (bzip2 1.0.6) to this one:

-------------------------------------------------------------------------------


1.0.7 (27 Jun 19)
~~~~~~~~~~~~~~~~

* Fix undefined behavior in the macros SET_BH, CLEAR_BH, & ISSET_BH

* bzip2: Fix return value when combining --test,-t and -q.

* bzip2recover: Fix buffer overflow for large argv[0]

* bzip2recover: Fix use after free issue with outFile (CVE-2016-3189)

* Make sure nSelectors is not out of range (CVE-2019-12900)

1.0.8 (13 Jul 19)
~~~~~~~~~~~~~~~~

* Accept as many selectors as the file format allows.
   This relaxes the fix for CVE-2019-12900 from 1.0.7
   so that bzip2 allows decompression of bz2 files that
   use (too) many selectors again.

* Fix handling of large (> 4GB) files on Windows.

* Cleanup of bzdiff and bzgrep scripts so they don't use
   any bash extensions and handle multiple archives correctly.

* There is now a bz2-files testsuite at
   https://sourceware.org/git/bzip2-tests.git


-------------------------------------------------------------------------------



   For futher information about bzip2 please read the man pages.  The man
   pages are the only ones that contain DJGPP specific information because
   they are the only one that can be remade with existing DJGPP tools.  The
   author no longer uses the texinfo format; he has switched to xml and it
   is not possible to recreate pdf, ps and html formated documentation from
   the distributed xml file.  Neitherless the original pdf, ps and html
   formated documentattion is supplied in the bz2-108d.zip archive.

   To run the scripts bzmore, bzdiff and bzgrep you will have to install the
   following DJGPP ports: difNNNb.zip, grepNNNb.zip, mktmpNNNb.zip and
   bshNNNb.zip




   The port consists of the usual four packages that have been produced using
   djdev205 (CVS repository code) and can be downloaded from ftp.delorie.com
   and mirrors as (time stamp 2020-04-18):
