Yes, we've been working about it. It's not ready yet, though.

Maybe it anyway makes a sense to migrate gzip to zlib? For example OpenWrt
which is Linux distro for very limited routers has both gzip and zlib. So
if gzip can reuse zlib then it may be smaller in size which is very
important for devices with 4mb of disk.

Also in the letter "bug#31065: Version 2??" I found that Paul Eggert said:

> 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.

I like this idea too because then all distributives just update gzip and
everything should work without rewriting scripts who using gzip.

Is any progress on this? Could you make an official announce about this?

Thanks for replying, Mark.
On that basis, I'll close this auto-created "issue", but that needn't
stop any conversation.

Charlie,

The library you speak of was created about 23 years ago. It=E2=80=99s =
called =E2=80=9Czlib=E2=80=9D. That TODO file looks like it hasn=E2=80=99t=
 changed much in the last quarter century.

As for gzip making use of that library, that has not yet occurred. And =
probably doesn=E2=80=99t need to. There does exist another =
implementation of gzip called =E2=80=9Cpigz=E2=80=9D which in fact uses =
zlib for compression and decompression. (It also offers parallel =
compression.)

Mark

Hello Gzip.

I am new to this project, and I read on the TODO file that there is a plan
to move the compression and decompression code into a library that gzip
would run on top of. Is this still a planned feature? If so, I am
interested in giving it a shot.

Would this be welcomed?

Thanks
Charlie
