Qt needs update to 5.14 and more maintainers

[jpathy]

qt 5.13 has been released for a while now.

indeed 5.14 is also out now. I would be glad to help package a newer version. It appears we may need to expand in the insufficient readme.

dtzWill/nixpkgs@f43e098, it appears patches were generated for qtbase with no documentation explaining how those patches were generated or how to remake them for new versions. Did you use a script? Considering sharing your thought process.

@ttuegel, The patched modules appear to be out of date. Are you still hosting the patched qt5 modules? I only checked out your fork of qtbase, but the version was only up to 5.9 leaving me curious how we got patches generated for newer versions?

If the patches didn't need significant changes between versions (which is pretty likely) then the contributor who updated Nixpkgs probably didn't open a pull request to my forked modules.

The problem here is that Qt 5.13 made significant changes to the build system. It will require a large effort to update the packages, possibly as much as packaging Qt in the first place. Unfortunately, I do not expect I will ever have time to sit down and figure this out myself, so the packages have stagnated.

So essentially this is gonna get really out of date, really quickly if someone doesn't repackage everything from scratch. Should we perhaps raise the severity of this issue to raise awareness before it gets too bad?

@worldofpeace Can you make this a priority for 20.03/pin this issue?

We totally need to help out @ttuegel here, but as nothing is (apparently) severely broken, and we're soo close to beta, I can't see someone contributing this until 20.09.
But if you have reasons to disagree please share them.

@ttuegel mentioned they'd never have the time figure that out themselves and it seems fairly difficult.
I do agree this is of high severity and needs the communities attention 👍

Yeah, I've just realized the feature freeze is next week. It makes sense to target the next release.

I know this isn't ideal, but Qt 5.12 is the current LTS version and has a longer support window than Qt 5.13 or Qt 5.14, so releasing NixOS 20.03 with Qt 5.12 isn't all bad.

I rebased the qtbase patchset as best as I could without having a clue about the Qt build system, and so far it seems to be surprisingly successful. I will report back on how the builds turned out tomorrow.

Okay so I could not really believe it at first but this seems to have worked:

TLSv1.3 is working fine now and also clipboard support on wayland is much better.

There are some regressions in qt5.14 that prevent some applications from running except with 5.13 (or at least they have avoided upgrading till now), so it would be good if they both end up in the package set.

We are now at Qt 5.14, I think we can close this.

Feel free to reopen and retitle "needs to update to 5.15".
