This reverts commit 7173eb87b8.
Reason for revert: This causes too big a rebuild for master (since GHC
uses srcOnly). This went unnoticed due to a stale ofborg rebuild count.
This matches how the default unpackPhase would copy from a store path
into the build directory, so it seems wise to match this here. On file
systems that support reflinks, this should improve performance as well.
Some packages rely on `uname` to configure the host target which breaks cross-compilation.
We can have more control over the evaluation of `uname` by placing `deterministic-uname` into the package's `nativeBuildInputs`.
However the current `deterministic-uname` is hardcoded to `buildPlatform`.
This PR introduces a build argument `forPlatform` to `deterministic-uname` which allows you to override the platform it reports.
Example:
```nix
deterministic-uname.override { forPlatform = stdenv.hostPlatform; }
```
https://github.com/NixOS/nixpkgs/pull/246164 but for hardlinks.
Mesa, among other packages, has binaries that are linked together and
can end up corrupted when the same binary is stripped through two
different names.
To resolve this, print out the device and inode number before each file
name, sort/uniq based on that, then cut it back out before stripping.
The symlink resolution logic is removed as the same file accessed
through two different links in `$paths` will necessarily have the same
numbers. File/directory within the paths listed in `$paths` are
correctly not (and were never) processed due to the `-type f` predicate
and (implied) `-P` option to `find`.
This change fixes cross-compilation for .NET packages (that are not
using .sln as project files). See relevant comment in the change list
for more details.
In addition to that, it removes dotnet-test-sdk that appears to be
broken, that is, dotnet --list-sdks does not recognize SDKs from PATH,
and when propagated from the check hook it was shadowed by inputs from
preceding hooks.
Note that dotnet-test-sdk used to work when it was introduced in PR
144062, but PR 155257 probably overlooked this case. However, currently
it is not used in Nixpkgs and I think dotnetCorePackages.combinePackages
should cover the intended use case for dotnet-test-sdk.
There should be no reason to use env here:
1. In places where it is used to run dotnet with environment variables,
the same can be done with shell syntax.
For example, `env "FOO=$bar" baz` is equivalent to `FOO="$bar" baz`.
2. Otherwise, it just unnecessarily forces PATH lookup for dotnet
command. In addition to that, some dotnet invocations did not use
env.
--frozen is stricter than we need in Nixpkgs. If a Cargo.lock is
slightly wrong, or (in my use case) if building a subproject that is
not a member of the top-level workspace, but the correct Cargo.lock
can be entirely resolved from the existing top-level Cargo.lock, it
should be deterministic, and shouldn't cause any problems, to let
cargo generate the new Cargo.lock. This should result in less need to
bother upstreams about fixing their Cargo.lock files in cases where
they could have been automatically fixed.
Adding cc to propagatedBuildInputs makes derivations with
makeBinaryWrapper in nativeBuildInputs run the cc-wrapper
setup hook. This isn't an issue for derivations using
stdenv, as the cc setup hook is already run by default.
However, derivations that are made with stdenvNoCC, e.g.
because they're made with runCommand, will not run the
cc-wrapper setup hook without this change.
For some reason the FreeBSD native compiler will not work
correctly without the setup hook.
The $DISPLAY variable has a format of [host]:num[.screen]. Previously,
the number would only be extracted properly if it had the form :num.
Allow all forms but correctly discard the unused parts.
