`stdenv.is*` defaults to `hostPlatform` which is technically incorrect
here, since what we are gating concerns the target platform only.
This would be a problem in practice if cross compiling from
x86_64-darwin to aarch64-darwin whilst using gcc which is probably
rare enough.
Replace `src = ./.` instances with more explicit source listings.
Otherwise, derivations will be rebuilt on any change to the files
defining them (e.g. formatting via nixfmt-rfc-style).
After enabling a separate binary output for the `Agda` Haskell package,
the new `bin` output measures ~100MiB, compared to the ~4.5GiB before.
Using it in `agdaWithPackages` reduces the closure size of an Agda
installation from ~5GiB to ~3GiB. The remaining space is taken up
mostly by the GHC backend.
With this change, derivations depending on `haskellPackages.Agda`
directly need to pick the right (binary) output. This concerns in
particular `emacsPackages.agda2-mode`.
`lib.getExe pkgsCross.riscv64.buildPackages.pkg-config` should return
`<prefix>/bin/riscv64-unknown-linux-gnu-pkg-config` not `<prefix>/bin/pkg-config`
This was added in d83e9c9573,
but included substitution variables `@blas@` and `@lapack@` that were
never substituted. It's not used anywhere in `nixpkgs`.
Ignore vendorSha256 when vendorHash is specified.
Throw when vendorHash isn't specified:
- "buildGoModule: Expect vendorHash instead of vendorSha256" when
vendorSha256 is specified.
- "buildGoModule: vendorHash is missing" otherwise.
`goModules.outputHashAlgo` is specified as null when vendorHash is not
empty, "sha256" otherwise.

This is convenient for debugging the underlying streamed image used by
`dockerTools.buildLayeredImage`.
Here's an example of how you might use this:
```console
$ nix repl ./.
nix-repl> dockerTools.examples.nginx.passthru.stream
«derivation /nix/store/9zczmlp2kraszx4ssmh6fawnlnsa5a4n-stream-nginx-container.drv»
```
The way we build python environments is subtly broken. A python
environment should be semantically identical to a vanilla Python
installation in, say, /usr/local. The current implementation, however,
differs in two important ways. The first is that it's impossible to use
python packages from the environment in python virtual environments. The
second is that the nix-generated environment appears to be a venv, but
it's not.
This commit changes the way python environments are built:
* When generating wrappers for python executables, we inherit argv[0]
from the wrapper. This causes python to initialize its configuration
in the environment with all the correct paths.
* We remove the sitecustomize.py file from the base python package.
This file was used tweak the python configuration after it was
incorrectly initialized. That's no longer necessary.
The end result is that python environments no longer appear to be venvs,
and behave more like a vanilla python installation. In addition it's
possible to create a venv using an environment and use packages from
both the environment and the venv.
