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.
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.
The only reason to pass build inputs is to extend the unpackPhase with
custom unpack commands. Eg: add "unrar" to unpack rar sources. And those
should really be passed as native build inputs. Why? Because
nativeBuildInputs is for dependencies that are used at build time but
will not propagate as runtime dependencies. And also, cross-compilation.
The build system already sets these properly to the absolute path so no
need to patch the libraries on darwin.

Previously, callPackage would try and fill the arguments such as `name`
and `src` which would cause problems if those existed as top-level
attributes. This also makes it clearer what part is the function
signature.
Then document the derivation inline in the code to explain the ellipsis
and various use-cases.
