Bug 177862 – Remove WOFF2 from Source/ThirdParty

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Frédéric Wang (:fredw)]

We can not do that until WOFF2 can be properly packaged, but let's try and prepare a patch for this.

[Tomas Popela]

And also we should remove brotli as it is a dependency of WOFF2

Sorry, I was not clear enough. We just want to remove the source from ThirdParty and use a jhbuild / system library instead.

Patch (WIP)

This is what I meant. But I just realized that I also need to make woff2_out.h public, so I'll need to update my WOFF2 branch on github.

I think this patch is what Tom will use in Fedora and RHEL until the license issue is resolved. This is also what we'll wind up using if we're unable to resolve the license situation with Google. Hopefully it won't come to that.

Thanks for working on this!

I think this one is not ready for review yet. We'll need to decide whether to tell Linux distros to package your fork, or whether we can convince Google to release a usable library so we don't need your fork, or whether it's best to just keep it under ThirdParty (and update it very regularly!) if we fail at convincing upstream to put this under a reasonable license. Let's wait a few days and see if upstream takes some action on this.

r=me, but we need to convince Carlos Garcia and Carlos Lopez before landing, since it was just released today. I think it makes sense to match what we are doing for libbrotli, though. And we are very early in the release cycle, so this is the right time to do it.

[Carlos Garcia Campos]

I'm ok

[Tomas Popela]

I tried this patch with freshly packaged woff2 for Fedora and it works (after applying one small, but fundamental patch). Thank you Fred!

Great thanks! Indeed I quickly edited the patch by hand before going to week-end and made that mistake!

It seems that the two Carlo's are fine with that change, so I'll land it.
