Preserving ArgvZero is supported from MacOS 14 Sonoma forward, which is
the current minimum supported version of nixpkgs. See
https://developer.apple.com/documentation/virtualization/running-intel-binaries-in-linux-vms-with-rosetta#Mount-the-Shared-Directory-and-Register-Rosetta
The necessity of this fix came up with python virtual environments,
because python uses the path of the executable (argv zero) to determine
if it should load a virtual environment or not. In the past this was
overriden with NIX_PYTHONEXECUTABLE, NIX_PYTHONPATH and
NIX_PYTHONPREFIX, but we stopped doing that for the python interpreter
so it works more like a normal python interpreter in nix.
Without those variables, in the rosetta emulated case, python was no
longer able to determine where it was called from, and thus could not
correctly activate virtual environments in that case.
Format all Nix files using the officially approved formatter,
making the CI check introduced in the previous commit succeed:
nix-build ci -A fmt.check
This is the next step of the of the [implementation](https://github.com/NixOS/nixfmt/issues/153)
of the accepted [RFC 166](https://github.com/NixOS/rfcs/pull/166).
This commit will lead to merge conflicts for a number of PRs,
up to an estimated ~1100 (~33%) among the PRs with activity in the past 2
months, but that should be lower than what it would be without the previous
[partial treewide format](https://github.com/NixOS/nixpkgs/pull/322537).
Merge conflicts caused by this commit can now automatically be resolved while rebasing using the
[auto-rebase script](8616af08d9/maintainers/scripts/auto-rebase).
If you run into any problems regarding any of this, please reach out to the
[formatting team](https://nixos.org/community/teams/formatting/) by
pinging @NixOS/nix-formatting.
these changes were generated with nixq 0.0.2, by running
nixq ">> lib.mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
nixq ">> mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
nixq ">> Inherit >> mdDoc[remove]" --batchmode nixos/**.nix
two mentions of the mdDoc function remain in nixos/, both of which
are inside of comments.
Since lib.mdDoc is already defined as just id, this commit is a no-op as
far as Nix (and the built manual) is concerned.
