Hi, some time ago Jean-loup, said on http://www.gzip.org/recover.txt that

"As you can see, all this is not a trivial task, so you should attempt it only if your data is very valuable. gzip 2.0 will have a new blocksize option, allowing to recover easily all undamaged blocks after the damaged portion."

I'm using gzip 1.9 from the PCLinuxOS.


Can you please let me know:

1 Is it still the plan to get this into 2.0?

2 If you are, when do you think 2.0 will be out??

Thanks loads

Martin

See http://zlib.net/pigz/ Hi Mark, thanks for replying. As for gzip vs. 2.0, I can say with confidence that we would strongly discourage such an effort here. If you want that capability, use pigz. While gzip is worth maintaining, it is definitely not the compression tool of the future. I've marked this as "notabug" and closed the issue in gzip's tracker, but you're welcome to continue replying here. ------------=_1522887542-29178-1 Content-Type: message/rfc822 Content-Disposition: inline Content-Transfer-Encoding: 7bit Received: (at submit) by debbugs.gnu.org; 4 Apr 2018 21:56:07 +0000 Received: from localhost ([127.0.0.1]:38726 helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1f3qNy-0004Mn-R5 for submit@debbugs.gnu.org; Wed, 04 Apr 2018 17:56:07 -0400 Received: from eggs.gnu.org ([208.118.235.92]:35068) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1f3pg7-0003L0-UN for submit@debbugs.gnu.org; Wed, 04 Apr 2018 17:10:48 -0400 Received: from Debian-exim by eggs.gnu.org with spam-scanned (Exim 4.71) (envelope-from ) id 1f3pg1-0000EZ-QY for submit@debbugs.gnu.org; Wed, 04 Apr 2018 17:10:42 -0400 X-Spam-Checker-Version: SpamAssassin 3.3.2 (2011-06-06) on eggs.gnu.org X-Spam-Level: * X-Spam-Status: No, score=1.5 required=5.0 tests=BAYES_50,HTML_MESSAGE, MIME_HTML_ONLY autolearn=disabled version=3.3.2 Received: from lists.gnu.org ([2001:4830:134:3::11]:54769) by eggs.gnu.org with esmtps (TLS1.0:RSA_AES_256_CBC_SHA1:32) (Exim 4.71) (envelope-from ) id 1f3pg1-0000EO-Mf for submit@debbugs.gnu.org; Wed, 04 Apr 2018 17:10:41 -0400 Received: from eggs.gnu.org ([2001:4830:134:3::10]:54272) by lists.gnu.org with esmtp (Exim 4.71) (envelope-from ) id 1f3pg0-000583-LZ for bug-gzip@gnu.org; Wed, 04 Apr 2018 17:10:41 -0400 Received: from Debian-exim by eggs.gnu.org with spam-scanned (Exim 4.71) (envelope-from ) id 1f3pfv-0000BG-K5 for bug-gzip@gnu.org; Wed, 04 Apr 2018 17:10:40 -0400 Received: from mout.kundenserver.de ([212.227.17.10]:38617) by eggs.gnu.org with esmtps (TLS1.0:DHE_RSA_AES_128_CBC_SHA1:16) (Exim 4.71) (envelope-from ) id 1f3pfv-0000Ae-9B for bug-gzip@gnu.org; Wed, 04 Apr 2018 17:10:35 -0400 Received: from null ([172.19.249.32]) by mrelayeu.kundenserver.de (mreue102 [212.227.15.179]) with ESMTPSA (Nemesis) id 0MSJ1n-1exWwF3ryd-00TWhd for ; Wed, 04 Apr 2018 23:10:32 +0200 Date: Wed, 4 Apr 2018 22:10:32 +0100 (BST) From: - - To: bug-gzip@gnu.org Message-ID: <1117840038.32709.1522876232781@email.1and1.co.uk> Subject: Version 2??

Hi, some time ago Jean-loup, said on http://www.gzip.org/recover.txt that

"As you can see, all this is not a trivial task, so you should attempt it only if your data is very valuable. gzip 2.0 will have a new blocksize option, allowing to recover easily all undamaged blocks after the damaged portion."

I'm using gzip 1.9 from the PCLinuxOS.


Can you please let me know:

1 Is it still the plan to get this into 2.0?

2 If you are, when do you think 2.0 will be out??

Thanks loads

Martin

But these version-number-lengthening events do make one think: not too long ago, I "incremented" 2.28 to 3.0 for grep. Now that you've raised the issue, maybe 2.0 to keep it short and simple.

I have a more-drastic idea in mind. Let's replace gzip's source code with pigz's, make the minimal set of changes needed to make it compatible with gzip and/or GNU in general, and call it gzip 2.0. In the meantime, we can keep the gzip 1 series around with the traditional implementation. From unknown Tue Aug 12 08:32:54 2025 X-Loop: help-debbugs@gnu.org Subject: bug#31065: Version 2??

The current gzip has the advantage of having been deployed over a very wide range of systems over a long time, so a lot of portability issues have been worked out. Absolutely. I expect that most of the work will be testing and portability-enhancement. For example, we could use the Gnulib pthreads module to insulate the gzip code proper from the vagaries of threads on non-POSIX platforms (this won't work as well as native threads, but that's OK, gzip will still run).

I totally support this idea too! that=E2=80=99s at least=E2=80=A6 some months I was collecting a maildir of = all the mail mentioning pigz and the future of gzip here and there, waiting to be put in the References header of a mail I was still composing to ask what was gzip going to be now there=E2=80=99s pigz that seems to replace everything,= and be maintained by people active here, and I=E2=80=99m ignoring all this just= to say +1 to this.
