X-Authentication-Warning: delorie.com: mail set sender to djgpp-bounces using -f Message-Id: <201306021804.r52I4YYx017407@delorie.com> Date: Sun, 02 Jun 2013 16:49:13 +0200 From: Juan Manuel Guerrero To: djgpp-announce AT delorie DOT com Subject: ANNOUNCE: Release 2 of the DJGPP port of GNU diffutils 3.3 uploaded. Content-Type: text/plain; charset=ISO-8859-15; format=flowed Reply-To: djgpp AT delorie DOT com This is a port of GNU diffutils version 3.3 to MSDOS/DJGPP. Diffutils are a collection of programs for finding differences between files: * diff -- displays differences between 2 files line by line; * diff3 -- displays differences between 3 files (usually, 2 files and their common ancestor); * sdiff -- displays differences between 2 files side by side, and allows to merge between them interactively; * cmp -- displays differences between 2 binary files byte by byte. The documentation of the package includes, in addition to the four programs mentioned above, also the manual for the Patch utility. This release fixes an issue concerning the assertions used in diffutils code. For a reason still unclear to me, when the code is compiled the NDEBUG macro is never set so all assertions are enabled. The DJGPP 2.04 port version supports symlinks. If the option --no-dereference is used then the symlinks are compared as ordinary files. If the option is omitted, the files referenced by the links will be compared instead. If the links are brocken, and the assertions are not disabled by defining NDEBUG, the diff program aborts with SIGABRT issuing the usual stack trace. This behaviour may be usefull during code development but not when using the program. With the assertion disabled an error message is printed and normal operation continues. The DJGPP 2.03 version of the port does not support symlinks so this is not an issue there. If for some reason you want to reenable the assertions, remove the NDEBUG definition in /djgpp/config_h.sed and configure and compile the sources again. DJGPP specific changes. ======================= - There are no DJGPP specific user visible changes compared with the last port. - The most notable change of the FSF distribution is that the DJGPP support has been dropped in favour of cygwin and MinGW support. - This port will detect at run time if it is running on an OS with LFN support or not and choose the appropriate temp file name pattern accordingly. E.g.: "sdiffXXXXXX" if LFN support is available, else "dfXXXXXX" will be used. - This port will honor also the DOS specific environment variable TEMP and TMP if TMPDIR is not set. If neither is accessible then P_tmpdir will define the location to store temp files. If this directory also does not exist then the current working directory will be used. - All other changes are those required to get gnulib sources compiled with djgpp and are not user visible. - To be able to build this port you will need to have LFN support. As usual, all djgpp specific files (config.bat, diffs, README files, etc.) are located in the /djgpp directory. The source package is now distributed configured for both DJGPP 2.03 and DJGPP 2.04. In the top srcdir there is a "_build.203" directory and a "_build.204" directory. For further information about GNU diffutils please read the info docs and NEWS file. Here is an extract of the NEWS file showing the user visible changes from the last port (GNU diffutils 3.2) to this one: * Noteworthy changes in release 3.3 (2013-03-24) [stable] ** New features --new-file (-N) and --unidirectional-new-file now allow comparisons to "-". A standard input that's closed acts like a nonexistent file. A file name containing spaces, double quotes, backslashes or control characters is now encoded in a diff header as a double-quoted C string literal. The escape sequences \\, \", \a, \b, \f, \n, \r, \t, \v and \ooo (a three-digit octal number between 0 and 255) are used. ** Packaging diffutils is now designed to build with Cygwin or MinGW rather than DJGPP. The ms subdirectory has been removed. ---------------------------------------------------------------------------- The port has been compiled using stock djdev203 (patchlevel 2) and consists of the usual three packages that can be downloaded from ftp.delorie.com and mirrors as (time stamp 2013-06-02): Diffutils 3.3 binary, info and man format documentation: ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/dif33br2.zip Diffutils 3.3 dvi, html and ps format documentation: ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/dif33dr2.zip Diffutils 3.3 source: ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/dif33sr2.zip The binaries have been produced a second time using the stock version of djdev204 beta library. This package is available at ftp.delorie.com and mirrors as (time stamp 2013-06-02): Diffutils 3.3 binary, info and man format documentation: ftp://ftp.delorie.com/pub/djgpp/beta/v2gnu/dif33br2.zip Send Diffutils specific bug reports to .
