 Robert Hensing (roberth) | so putting meta in derivations without impacting hashing was actually kinda low hanging fruit

| Taeer Bar-Yam | What is the schedule and system by which we upgrade the nixpkgs pin in the nixos/nix repo? | 02:08:40 |
| Robert Hensing (roberth) | Taeer Bar-Yam: latest stable by default. Sometimes temporarily nixos-unstable leading up to NixOS release. Not super organized schedule | 02:09:57 |
| Robert Hensing (roberth) | (last time I checked) | 02:10:21 |
| Robert Hensing (roberth) | or whatever. It's undocumented | 02:10:31 |
 Sergei Zimmerman (xokdvium) | Have a bump for 25.11 now: https://github.com/NixOS/nix/pull/14688 | 02:10:33 |
| Taeer Bar-Yam | I'm going to try to test it out tomorrow. 25.11 has a version bump for meson that inshallah makes some fuzzing stuff simpler | 02:12:22 |

so putting meta in derivations without impacting hashing was actually kinda low hanging fruit
https://github.com/NixOS/nix/pull/14686 I think i want better roadmaps that are actually followed up on for new experimental features. Nix starts to look like haskell with it's preamble of language extensions | 06:43:34 |

| Taeer Bar-Yam | How can I be getting the error message
error: output '/nix/store/6s177q59d74xhxkj8p54bga156d9g84b-test' is not allowed to refer to the following paths:
/nix/store/6s177q59d74xhxkj8p54bga156d9g84b-test
Without hitting the checkOutputs() function at all? That text doesn't appear anywhere else in the code!
Things I did:
- adding a debug print statement
std::cout << "HERE\n"; (didn't get printed)
- running with a breakpoint in gdb (didn't get hit)
- commenting out the relevant
throw (threw the error anyways)
- running on a fresh derivation in case i was hitting some cache (same results)
- putting obvious errors in
checkOutputs() (compile error. so I am recompiling this function)
- editing
src/nix/main.cc in obvious ways to make sure I was running the binary that was getting built (obvious changes showed up, so I'm successfully building and running the right binary)
