Fix cairocffi build #56839

avnik · 2019-03-04T19:52:05Z

Motivation for this change

cairocffi doesn't build, preventing qtile from build.
(patch doesn't applying correctly)

Patch was refreshed, as well as more packages required for tests added.

FYI cairocffi is 3.5+ library now. Probably I should add assert as well.

@FRidh @avnik I'd propose to add an cairoffi_1 package as well (similar to cairosvg1) to retain Python 2 support for now. This affects thumbor, graphite-web and cairosvg1 and I think it's too early to drop Python 2 support if some dependants still need it.

Also wondering if the Python update script should contain some functionality to actually test the package before bumping it (and pushing this to master).

@Ma27 cairocffi_py2 be better name, than _1.

Other option -- add some backporing patch to this package, I am ok with both solutions.

Ack. Didn't look at the package's version when writing this 😅

Can you please be more precise in what you mean? Not sure if I understand correctly what you meant :)

I mean, if you take commit, which removing 2.x support, make reversing patch, and will support it ;) If you want overtake cairoffi, you are welcomed -- I care about it, because it transitive dependency of qtile.

I doubt that it'll be that easy. Python 2.x and 3.x diverge pretty much.

But I'll have a look at this and see how to proceed here :)

I know. I am in middle of porting mid size project from 2.x and gevent to 3.x and aio. Lot of pain and sorrows ;)

Ma27 · 2019-03-09T22:21:05Z

Just a short update: I created a cairocffi_0_9 package locally and played around with it. I'll push this tomorrow to this PRs branch as I'm fairly sleepy atm :)

Ma27 · 2019-03-10T10:27:53Z

I pushed three commits on top of your branch:

8d23630: qasm2image doesn't support Python older than 3.5. It's more obvious to raise an error since this package doesn't support old Python rather than breaking the evaluation when trying to use the cairocffi derivation.
ad550de: move the entire cairocffi build instructions into a generic function that is invoked for cairocffi 1.0 and 0.9. The older version should be supported for now to keep older software like thumbor working. I'd probably revert that before 19.09 as Python 2.x will be dropped by the end of the year.

This affects the following packages:
- cairosvg1: Built with cairocffi 1.x by default, but when using Python 2.x (which is still supported here), cairocffi can be overridden by cairocffi_0_9. (Also wondering if we should add a cairosvg1_py2 to make this more obvious.
- thumbor: Python 3.x support is in progress, but until then we can only build with Python 2 here.
- graphite-api with Python 2.x (nix-build -E 'with import ./. {}; pythonPackages.graphite_api.override { cairocffi = pythonPackages.cairocffi_0_9; }')
- graphite_web (doesn't work with Python 3.x)
- and probably some more...
da86a8e: unbreak thumbor (by using cairocffi_0_9 and adding some minor fixes to the test suite).

@FRidh @avnik it would be great if you could review this as well :)

How about

Suggested change

inherit (callPackage ../development/python-modules/cairocffi {}) cairocffi cairocffi_0_9;

cairocffi = if isPy3k then

(callPackage ../development/python-modules/cairocffi {}).cairocffi

else

(callPackage ../development/python-modules/cairocffi {}).cairocffi_0_9;

You're right! That made the fix for thumbor far easier. I also exposed cairocffi_1_0 and cairocffi_0_9 for now as it seems to be a common pattern to add all versioned attributes to the package set and alias one of those to the default package name.

I'd prefer not to expose them because pythonPackages should only contain a single version of each package. Btw, I think the prettiest way to do this is by using let inherit (calPackage ...) cairocffi cairocffi_0_9; in if isPy3k ....

The commit messages for cairocffi should say pythonPackages.cairocffi: ....

According to `setup.py` in 0.8 older Python wouldn't work.

This patch ensures that the currently broken `thumbor`[1] package builds and works again. The following problems were fixed: * Rather than placing required packages (like `gifsicle` or `exiftool`) into the build input list, we reference them explicitly where needed to ensure that the package works after the build without further installs. * Skip the `test_redeye_applied` test case which is broken for a while now. [1] https://hydra.nixos.org/build/90290998

This patch ensures that Python2 can be used if cairocffi is used. Version 1.0 dropped Python 2 support.

Cherry picked in ab89b6b..3274b1d.

Btw, I also pushed f721655 (cherry picked in cdc714f).

kamilchm · 2019-03-18T00:38:29Z

@avnik is there a way to use it with overridden withXcffib like in

nixpkgs/pkgs/applications/window-managers/qtile/default.nix

Lines 3 to 6 in 6004e5d

    
           let cairocffi-xcffib = python37Packages.cairocffi.override { 
        
               withXcffib = true; 
        
             }; 
        
           in

?
I can't make it work after this change.

dotlambda · 2019-03-18T05:51:32Z

@kamilchm Sorry for messing that up. An easy way to make it work would be to use three files: default.nix and 0_9.nix, which both call common.nix. I'll make the change once I have time for it.
