Good work. I just tried it out. Both reading and writing seemed to
work fine. Generating a gem for my largest project, windows-pr, worked
fine as well.
It must match the current Zlib::GzipWriter interface
It must be cross platform
It must be able to generate a proper gem file from a gemspec (the
acid test)
It must be contributed back to the zliby project
It must be done within 60 days of this post
And the winner is…Park H.! We actually had two competitors for
the bounty (much to my surprise), and it was very close (again, to my
surprise), but in the end Park’s code passed an acid test that
Charles’ code did not.[1]
So, congratulations to Park H. for not only creating a
Zlib::GzipWriter implementation, but for also creating a pure Ruby
version of the underlying zlib 1.2.3 library!
WOOHOO!
Regards,
Dan
[1] However, I hate to see Charles go unrewarded for his wonderful
efforts, so any matchers are free to distribute their bounties as they
see fit.

This is just awesome, thanks Dan for putting up some cash to make this
happen! Compression was more difficult then decompression and I just
didn’t have the time. Going to look into combining Park’s code into
zliby… though Charles stuff looks interesting too…
I have some bucks with Park and Charles names printed on them
Park: I have your Paypal info, will send you as soon as possible.
Charles: can you tell me your paypal email?
Again: do anyone knows a good platform to to bounties for open source
projects?

Thanks Luis, but never mind, it was more about the challenge, and also
supporting the effort to ease problems on windows. I primarily use ruby
on windows, and make use of the fruits of your (one click installer),
and daniel berger’s (win32 process, sys-*, et al) labors every day (at
work that is :). Props to you guys for making ruby on windows useable…

Charles,
I like how you laid out your project and whatnot. My “dream” is to make
zliby more then just a zlib compression library, but a more general
compression library and command line tool. Your compression code seems
to be more in the same style as my decompression implementation, any
qualms against me incorporating some of your stuff?
I also added Park to the zliby ruby-forge project, if you’d like I can
add you as well, or add you as a collaborator on the zliby github
project.
add you as well, or add you as a collaborator on the zliby github
and a pure ruby zlib, all thats probably missing is bzip2, and bwt is
fairly straight forward (I believe I saw a python implementation in
around 100 lines).
I’m really hoping some of that javascript vm goodness will find its way
to ruby though (or psyco equivalent or whatever), because without it,
pure ruby compression (or any algorithmic code) remains unsuitable for
general purpose use.
I didn’t notice much of a slowdown with Park’s version when installing
gems or building gems, though I didn’t do any sort of formal
benchmarking.
It would be interesting to see some real benchmarks with MRI, JRuby and
1.9.

Hi Michael,
Sure feel free to add me on the rubyforge/github, or just copy the
relevant files back in if you prefer. There’s a few small fixes needed
to the deflate code, but after that it might be a good candidate for
inclusion.
The idea of a general ruby compression library is nice. With rubyzip,
and a pure ruby zlib, all thats probably missing is bzip2, and bwt is
fairly straight forward (I believe I saw a python implementation in
around 100 lines).
