@adis:blad.isadisbladis
In reply to @tyberius_prime:matrix.org
adisbladis: Hi, are you still working on poetry2nix?

For various reasons I haven't worked on anything Nix related for a bit.

The reasons are many-fold:

  • Personal (I don't want to get into details here, not relevant to the overall community regardless)

  • I don't exactly enjoy the maintenance aspect
    Overrides et al was something I always saw as a stop gap, but now takes up the brunt of maintenance time. This is not what I enjoy working on.

  • Ongoing political conflicts in Nix
    I have extremely low patience for social BS at the best of times, this is too much to handle.

I have some pretty large changes that I want to do to how Nixpkgs deals with Python in general that would break things drastically for some people. Dealing with any sort of social fallout in this climate is something I see as untenable.

  • I barely even use Python myself any more

  • Companies make money off poetry2nix, I make none
    This reality makes me question how much unpaid time I should put into the project.

@tyberius_prime:matrix.orgTyberiusPrime (smilodon inopinatus) adisbladis: Thanks for the explanation. Glad to hear you haven't been run over by a bus or something, I do tend to worry. 05:08:05

@tyberius_prime:matrix.orgTyberiusPrime (smilodon inopinatus)So, I'm 98% certain that preferWheels just doesn't work.12:34:55
@tyberius_prime:matrix.orgTyberiusPrime (smilodon inopinatus)but I sure have trouble tracing the code and finding out why.12:49:32
@tyberius_prime:matrix.orgTyberiusPrime (smilodon inopinatus)correction, it works for some packages and does not for others ?!14:22:16

@FRidh:matrix.orgFRidhIt would be great if this PR could be merged adding a cargo hash https://github.com/nix-community/poetry2nix/pull/172609:10:13
@truh:matrix.orgtruhI'm trying to investigate why opencv is no longer building (probably the same as https://github.com/nix-community/poetry2nix/issues/1715). Do the opencv packages in poetry2nix rely on the instructions from https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/opencv/4.x.nix ?10:37:52

my work in progress giant PR should fix that 'en passant'

I don't think they do, reading the source.

@tyberius_prime:matrix.orgTyberiusPrime (smilodon inopinatus)and once again, my mega-PR fixes that as well.10:04:39
@tyberius_prime:matrix.orgTyberiusPrime (smilodon inopinatus)

by doing

 postPatch = ''
              sed -i pyproject.toml -e 's/numpy==[0-9]\+\.[0-9]\+\.[0-9]\+;/numpy;/g'
              # somehow the type information doesn't get build
              substituteInPlace setup.py --replace-fail '[ r"python/cv2/py.typed" ] if sys.version_info >= (3, 6) else []' "[]" \
              --replace-fail 'rearrange_cmake_output_data["cv2.typing"] = ["python/cv2" + r"/typing/.*\.py"]' "pass"
            '';

10:04:57
@tyberius_prime:matrix.orgTyberiusPrime (smilodon inopinatus)(basically, by saying to not build the py.typed file)10:05:14
@truh:matrix.orgtruh My current workaround is p2n.defaultPoetryOverrides.extend (self: super: { opencv-contrib-python = super.opencv4; }) & dontCheckRuntimeDeps = true; but your patch thing looks more reasonable 10:07:42
@truh:matrix.orgtruhHonestly feels like a bit of a waste not to use all those handcrafted build expressions in nixpkgs, I guess those only need to work with specific versions so maybe more problems than gain by using them.10:09:48
@tyberius_prime:matrix.orgTyberiusPrime (smilodon inopinatus)yeah, I've been at least stealing the patches from nixpkgs, but you're right, they only need to work with one exact version10:11:05
@truh:matrix.orgtruhI somewhat surprised opencv-python ever worked without the nixpkgs stuff, given that they download stuff during the cmake build10:11:12

I can't comment on that, since I have no clue about opencv or it's build process. I just went and tried to fix as many packages as possible
10:11:50
@tyberius_prime:matrix.orgTyberiusPrime (smilodon inopinatus)(and my test 'matrix' is already bonkers... I try to build 17k python packages, each individually locked by poetry, and that ends up being >100k package*version builds.)10:12:55
@tyberius_prime:matrix.orgTyberiusPrime (smilodon inopinatus)(my nixpkgs copy doesn't seem to have opencv-python at al. or maybe not in python-modules at least)10:13:34

@truh:matrix.orgtruhpython3Packages.opencv4 is https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/opencv/4.x.nix10:14:42
@tyberius_prime:matrix.orgTyberiusPrime (smilodon inopinatus)no I do it because I've failed my will power check and now I have a brain bug that says 'must build more packagesssss'10:14:47
@tyberius_prime:matrix.orgTyberiusPrime (smilodon inopinatus)but I'll get this PR landed, and then I'll have a look at whether or not poetry2nix is actually reading the build-systems from pyproject.toml ^^10:15:51
@tyberius_prime:matrix.orgTyberiusPrime (smilodon inopinatus)but I really wanted it to got from 41% build packages to 82%... I'm only at 80% 10:16:29
@truh:matrix.orgtruhno more manual overrides for setuptools, etc?10:16:30
