I've had better luck creating statically-linked binaries that work than
dynamically-linked ones, so this is needed quite practically.
(cherry picked from commit 676df1cf2d)
I realized what rhelmot did in 61202561d9
(specify what packages just need `stdenvNoLibc`) is definitely the right
approach for this, and adjusted NetBSD and OpenBSD to likewise use it.
With that change, we don't need these confusing and ugly `*bsdCross`
package sets at all!
We can get rid of a lot more libc-related `*Cross`, and I will do so
soon, but this is the first step.

libiconv-darwin depends on Meson, which (indirectly) depends on
libiconv. When libiconv-darwin is set as libiconv, it will cause an
infinite recursion. Avoid the infinite recursion by using libiconvReal
in stage 1. Every stage after that can use libiconv-darwin.
The cc and bintools wrapper contained ad hoc bootstrapping logic for
expand-response-params (which was callPackage-ed in a let binding). This
lead to the strange situation that the bootstrapping logic related to
expand-response-params is split between the wrapper derivations (where
it is duplicated) and the actual stdenv bootstrapping.
To clean this up, the wrappers simply should take expand-response-params
as an ordinary input: They need an adjacent expand-response-params (i.e.
one that runs on their host platform), but don't care about the how.
Providing this is only problematic during stdenv bootstrapping where we
have to pull it from the previous stage at times.
We don't need to artificially make sure that we can execute the wrapper
scripts on the build platform by using stdenv's shell (which comes from
buildPackages) since our cross infrastructure will get us the wrapper
from buildPackages. The upside of this change is that cross-compiled
wrappers (e.g. pkgsCross.aarch64-multiplatform.gcc) will actually work
when executed!
For bootstrapping this is also not a problem, since we have a long
build->build platform chain so runtimeShell is just as good as
stdenvNoCC.shell. We do fall back to old ways, though, by explicitly
using the bootstrap-tools shell in stage2, so the adjacent bash is only
used from stage4 onwards. This is unnecessary in principle (I'll try
removing this hack in the future), but ensures this change causes zero
rebuilds.
As of late, `final: prev: …` for overlays has become more prevalent in
newer code. This is also exhibited in some code (presumably added
recently) in stdenv. This change is not about any merits or demerits of
any naming convention, but rather aims to make the nomenclature in
stdenv bootstrapping consistent to lessen confusion.
I've chosen to stick to `self: super: …` convention because:
1. It is more common in the code as it stands.
2. Using `final: prev: …` makes the code more confusing, als it causes
`prev` to be in scope alongside `prevStage`. `prevStage` actually
bears no relation to `prev` even though their naming suggests it,
making it easy to confuse them (the former is the (final) package set
of the previous stage while the latter is just the `prev`/`super` of
the overlay “chaining” on a completely fresh package set, i.e. `prev`
doesn't even relate to the previous stage's `overrides` argument).
This change also corrects a naming error in stdenv/native which had no
effect, as the variables were unused.
This fixes using inputDerivation on derivations that are fixed-output.
Previously:
```
nix-repl> drv = runCommand "huh" { outputHash = "sha256-47DEQpj8HBSa+/TImW+5JCeuQeRkm5NMpJWZG3hSuFU="; outputHashAlgo = "sha256"; outputHashType = "flat"; } "touch $out"
nix-repl> drv.inputDerivation
«derivation /nix/store/d8mjs6cmmvsr1fv7psm6imis5pmh9bcs-huh.drv»
nix-repl> :b drv.inputDerivation
error: fixed output derivation 'huh' is not allowed to refer to other store paths.
You may need to use the 'unsafeDiscardReferences' derivation attribute, see the manual for more details.
```
Fixes: https://github.com/NixOS/nixpkgs/issues/304209
Nixpkgs tries to print a helpful message when it blocks unfree packages,
but the suggestion is subtly broken. The predicate only matches on the
package's name, but the suggestion includes the full name-version pair.
Fixed by formatting the message with the same function as the predicate.
This issue arises because check-meta defines its own local getName with
semantics divergent from lib.getName. The former includes the version,
the latter does not.
Example Before:
Alternatively you can configure a predicate to allow specific packages:
{ nixpkgs.config.allowUnfreePredicate = pkg: builtins.elem (lib.getName pkg) [
"obsidian-1.5.12"
];
}
Example After:
Alternatively you can configure a predicate to allow specific packages:
{ nixpkgs.config.allowUnfreePredicate = pkg: builtins.elem (lib.getName pkg) [
"obsidian"
];
}
Fixes#303116
checkValidity has the responsibility to check if a derivation's attributes are valid.
Previously it also had the overloaded task of creating a subset of meta attributes:
- unfree
- broken
- unsupported
- insecure
Not only is this overloading strange, these attributes were only ever consumed by `commonMeta`.
This change makes checkValidity _only_ check for validity, and removes the creation of any meta attributes from `checkValidity` and moves them to `commonMeta`.
This is technically a breaking change but I don't expect any external nixpkgs consumers to rely on these implementation details.
