Increase the license options.

[Lokathor]

Per https://github.com/Frommi/miniz_oxide/issues/66, this adds the Zlib license as a possible license for users of the crate. While we're at it, it's probably best to also add the Apache-2.0 license as an option.

I expect this to be fairly uncontroversial, but this would need sign off from past code contributors (alphabetical order):

• [x] alexcrichton
• [ ] arbitrix
• [x] ctjhoa
• [x] dholbert
• [x] dingelish
• [x] eminence
• [x] FauxFaux
• [x] fhanau
• [x] Frommi
• [x] golddranks
• [x] ignatenkobrain
• [x] jonas-schievink
• [x] matklad
• [x] oyvindln
• [x] RReverser
• [x] Shnatsel
• [x] srijs
• [x] vlad20012
• [ ] wehlutyk

If @Frommi is still on board with the idea then we can start pinging the rest of people.

[Lokathor]

Frommi checked their box, so I'll ping everyone else: @arbitrix @ctjhoa @dholbert @dingelish @eminence @FauxFaux @fhanau @golddranks @ignatenkobrain @jonas-schievink @matklad @oyvindln @RReverser @Shnatsel @srijs @vlad20012 @wehlutyk

[dingelish]

Signed-off by Yu Ding @dingelish :p

[ignatenkobrain]

Fine with me. But please add texts of those licenses into the tree.

[Lokathor]

Ah, can do.

[ctjhoa]

I'm ok too

[matklad]

I agree to adding Zlib and Apache 2.0 licenses

[FauxFaux]

I don't even remember contributing, which probably means that my contribution is too small for you to even ask.

But, yes, please do.

[golddranks]

I agree to adding Zlib and Apache 2.0 licenses.

[Shnatsel]

I license past and future contributions under Zlib OR Apache-2.0 or MIT license, allowing licensees to chose any one at their option.

[jonas-schievink]

I'm fine with this too

[oyvindln]

I'm fine with this.

[Lokathor]

Apologies, there was apparently a copy/paste mixup and @alexcrichton wasn't initially on the list, so you get a ping too.

[srijs]

👍 fine by me

[eminence]

I agree to adding Zlib and Apache 2.0 licenses

[dholbert]

I've only contributed one commit which was a 1-character typo-fix, so I'm arguably not really a code contributor. :) But, setting that aside: sure, I'm fine with this license change.

[fhanau]

I also agree to adding the licenses.

[vlad20012]

I agree to adding Zlib and Apache 2.0 licenses

[RReverser]

No problem from my side.

[alexcrichton]

I agree to this change of licenses.

[Lokathor]

I made a gaffe and would like to apologize to everyone.

The PR had been set to affect the miniz_oxide_c_api. I intended to change things for the miniz_oxide crate. I was not clear on the repo organization at the time (the intended crate is in a sub-directory), and so I altered the wrong Cargo.toml and added the new licenses all at the repository root.

I have pushed the proper changes so that this PR now applies to just the miniz_oxide crate.

Since the relicense has been signed off on by everyone who has touched that crate specifically:

• @Frommi I ask that you merge this PR as is, and please push out a release to crates.io some time soon.
• I'll open a second PR for the C API crate to also get the re-license treatment, with a ping to just the one last contributor we'd need a sign off from for the C api to be also re-licensed.

[oyvindln]

Okay, so the remaining two contributors, @arbitrix and @wehlutyk contributed to the C API part only so I think this should be fine to merge, looks like both have not been active lately. (@arbitrix contribution was just removing a line, so I don't know if that is something that counts as needing approval either.)

[Lokathor]

@oyvindln i resolved the merge conflicts that came up recently. Can you merge and publish yourself? Or do we need to keep waiting for @Frommi ?

[oyvindln]

I can do that, may wait a bit with publishing unless it's urgent, would like to get #97 in.

[Lokathor]

Understandable. I'll subscribe to that PR too.

Thanks for getting to this!

[arbitrix]

I agree to this change of licenses.
