This is supposed to shareDocName to a fallback value if it can't be
determined from looking at the configure script. But the conditional
checked whether shareDocName was set, rather than if it wasn't. This
meant that if shareDocName had been detected from a configure script,
it would be immediately overridden by the package name, and if it
couldn't be detected, shareDocName would remain unset.
This resulted in QEMU installing files like $out/share/doc/index.html,
which should of course have been in $out/share/doc/qemu/index.html.
An interesting side effect of this is that, since
9f8751528c when this code was added, the
detected package name has never actually been used for installing
documentation, because it would always be overridden. So this patch
will actually enable that for the first time, four years later.

Cargo sets `CARGO_FEATURE_*` for all features when running a build
script:
https://doc.rust-lang.org/cargo/reference/environment-variables.html#environment-variables-cargo-sets-for-build-scripts
Some crates have build scripts (e.g. openblas-src) that rely on the
feature variables being properly set.
Since we now need several representations of features, this change
also updates `createFeatures` to be a list of features, rather than
`rustc` feature arguments. `configureCrate` and `buildCrate` then
build the required representations as-needed.
Fixes#68978
When building an environment if two paths conflict but one or both are
symbolic links and they resolve to the same real path, the conflict is
discarded because the contents of both paths are the same. One of them
is chosen and there is no need to recur into them in order to build
deeper symbolic links.
We can use cacert to validate that the data passes SSL certificates.
Normally, this doesn’t happen because we already have the hash, but in
the hash = "" case we don’t.
xchg is advertised as a bidirectional exchange dir, but file content
transfer from host to VM fails due to caching:
If a file is read in the VM and then modified on the host, subsequent
re-reads in the VM can yield old, cached data.
This is caused by the use of 9p's cache=loose mode that is explicitly
meant for read-only mounts.
9p doesn't provide any suitable cache modes, so fix this by disabling
caching.
Also, remove a now unnecessary sync in the test driver.
This adds the `validatePkgConfig` hook, which can be used to validate
pkg-config files in the output(s). Currently, this will just run
`pkg-config --validate` on all `.pc` files, capturing errors such as
the issue that was fixed in #87789.
The hook could be extended in the future with more fine-grained
checks.
In https://github.com/NixOS/nixpkgs/pull/58431 the authors ensured that
the resulting layer.tar would always list
/nix/
/nix/store/
first to fully comply to the tar spec. Various refactorings later it is only
ensured to create /nix/ but NOT /nix/store anymore. Instead tar transformed
them to /nix/nix and /nix/nix/store.
This is much better because then we can freely keep the comments up to
date without causing mass rebuilds.
Someday, somebody should make the same change with `cc-wrapper` and
`bintools-wrapper`.
There are several tarballs (such as the `rust-lang/rust`-source) with a
`Cargo.toml` at root and several sub-packages (with their own Cargo.toml)
without using workspaces[1].
In such a case it's needed to move into a subdir to only build the
specified sub-package (e.g. `rustfmt` or `rsl`), however the artifacts
are at `/target` in the root-dir of the build environment. This breaks
the build since `buildRustPackage` searches for executables in `target`
(which is at the build-env's root) at the end of the `buildPhase`.
With the optional `buildAndTestSubdir`-argument, the builder moves into
the specified subdir using `pushd`/`popd` during `buildPhase` and
`checkPhase`.
Also moved the logic to find executables and libs to the end of the `buildPhase`
from a custom `postBuild`-hook to fix packages with custom `build`/`install`-procedures
such as `uutils-coreutils`.

I hate the thing too even though I made it, and rather just get rid of
it. But we can't do that yet. In the meantime, this brings us more
inline with autoconf and will make it slightly easier for me to write a
pkg-config wrapper, which we need.
Some PECLs depend on other PECLs and, like internal PHP extension
dependencies, need to be loaded in the correct order. This makes this
possible by adding the argument "peclDeps" to buildPecl, which adds
the extension to buildInputs and is treated the same way as
internalDeps when the extension config is generated.
flat hashes can be substituted through hashed-mirrors, while recursive
hashes can’t. This is especially important for Bazel since the bazel
fetch dependencies can come from multiple different methods (git,
http, ftp, etc.). To do this, we create tar archives from the
output/external directory, which is then extracted to build. All of
the Bazel hashes are all updated.
If a user provides `nativeBuildInputs = [ llvmPackages.bintools ]` or any other
package containing a `${prefix}/bin/diff`, the builder could use it instead
of the standard unix `diff`, causing a build failure.
This updates the call to specify an abspath to `diff` and avoid reliance on `PATH`.
Resolves#87081
Calculating the tarsum after creating a layer is inefficient, since
we have to read the tarball we've just written from the disk.
This commit simultaneously calculates the tarsum while creating the
tarball.
Appending to an existing tar archive repeatedly seems to be a quadratic
operation, since tar seems to traverse the existing archive even using
the `-r, --append` flag. This commit avoids that by passing the list of
files to a single tar invocation.
When running `cargo test --release`, the artifacts from `buildPhase`
will be reused here. Previously, most of the stuff had to be recompiled
without optimizations.
