Haskell library system-fileio tests fail

[tel]

Seems like a hardcoded path problem? The log is below.

For now, I'm able to build with doCheck = false, though.

Have you reported this issue to the library authors?

[tel]

I haven't. My nix-fu is weak, but it appears to be a nix packaging issue?

Or is the policy to try to convince library authors to ensure that all of their extra files are properly caught by cabal2nix?

A similar problem was occuring with shake a little while back, but I haven't tested it recently.

[peti]

What makes you think that this might be a Nix packaging issue?

Note that cabal2nix doesn't package anything. We build the distribution tarballs from Hackage.

[tel]

Because it appears to be failing to find a file ¡¢£.txt in the location the test expects it to be. I suppose I'm working on the assumption that this test passes if you were to just cabal get it. I can try to confirm that.

[peti]

Again, we download release tarballs from Hackage, just like cabal get does. The environment this package builds in Nix is identical to that in which it builds on any other platform. There are no extra files, nor are there any files missing.

[peti]

Also, note that the test suite succeeds just fine when run on our CI: http://hydra.nixos.org/job/nixpkgs/haskell-updates/haskellngPackages.system-fileio.x86_64-linux.

[tel]

Interesting, I'll dig in more and open the issue for the library itself.

[peti]

To me, it looks like the weird file name is causing trouble on your system, maybe because your file system or locale environment doesn't support it. I'm just guessing, though.

[peti]

Tests succeed on Hydra; seems to be an issue with the machine running the build that ought to be fixed upstream.

[tel]

Yep—I agree. Closing here.

[tel]

Thanks!

[jml]

I ran into this issue. @tel did you discover what it was about your system that made it fail? Is there an upstream bug I can follow?

[jml]

Never mind, found fpco/haskell-filesystem#5 which is the upstream bug.

[tel]

Yeah, I've been just sitting on it since then. It seems like a Mac+Unicode kind of thing.

0af5205 re-enables the test suite on Darwin.
