 matthewcroughan | Why is switch-to-configuration rust when I said system.switch.enableNg = false anyway? | 15:11:29 |
| matthewcroughan | and why is it rust when nixos-rebuild-ng is python anyway? | 15:11:59 |
 K900 | Because old stc has been removed | 15:12:15 |
| matthewcroughan | The log for failure is very very obscure | 15:12:45 |

| matthewcroughan | how get more logs | 15:13:33 |
| matthewcroughan | the build.rs isn't verbose enough | 15:13:37 |
 Alyssa Ross | strace in nix-shell is a nice easy way | 15:16:53 |
 dramforever | i thought macos has that header | 15:24:32 |
 emily | so it does | 15:56:25 |
| dramforever | oh no, is it wrong dynamic linker or something | 16:00:54 |
| dramforever | the build.rs just uses unwrap(), so this isn't even in build.rs | 16:01:35 |
| dramforever | unrelatedly, i don't know if this is excessive but it seems justified to: https://github.com/NixOS/nixpkgs/pull/453259 | 16:04:19 |
| matthewcroughan | Seems good to me, I don't know how to test the mercurial stuff with google-re2 | 16:05:35 |
| matthewcroughan | * Seems good to me, I don't know how to test the mercurial stuff with google-re2 though | 16:05:38 |
| matthewcroughan | I mean it might build, but who knows whether it works at runtime with mercurial the same exact way that is expected | 16:06:30 |
| dramforever | i checked the code in mercurial and it does runtime checks for feature testing | 16:07:28 |
| dramforever | like for example if it's missing test_match it uses match instead | 16:07:42 |
| dramforever | oh they even have code that add fb-re2 compat https://phab.mercurial-scm.org/D10284 | 16:11:18 |
| dramforever | so mercurial most definitely does not specifically depend on fb-re2 | 16:12:48 |
| dramforever | and given that the actual regex works the same under the hood, i really doubt there will be any problems | 16:13:12 |
| dramforever | oh they also catch re2 errors and fall back to normal re | 16:13:44 |
| matthewcroughan | so they even noticed that the code was bad and then fallback | 16:19:10 |
| matthewcroughan | lolwut | 16:19:11 |
| matthewcroughan | Bah so close to making a fully switchable system by swapping Nix out for Lix | 16:19:47 |
| matthewcroughan | But Lix fails with llvm in ways that nix doesn't | 16:20:01 |

| dramforever | not really bad, more that fb-re2 didn't do bytes | 16:20:32 |
| dramforever | but i guess in a way | 16:20:39 |
| dramforever | that means it's python 2 brained | 16:20:49 |
