A handful of kernel modules use glob patterns to express their
firmware dependencies. (`git grep 'MODULE_FIRMWARE.*\*'`)
Previously, we weren't handling these patterns. Now, we are.
Ideally fetch-yarn-deps could do like some other fetchers and support
using SSL_CERT_FILE if it exists and also only verify integrity on FOD
hash unless using an empty/test hash.
But this should keep at least the same semantics as before the recent
Node.js change to stop using the built-in certificate store in favor of
the system one (which does not exist by default in the build sandbox).
Not sure how this ever worked but tar was trying to archive /proc and /sys, which failed to work.
Since this is never useful for containers to do, we exclude this now in the proot case.
Also fakeroot is not needed when proot is used as it provideds the same feature.
We now cleanly seperate those cases as both are kind of hacks and it's more likely
that the combination will just trigger new bugs.
when bubblewraps tries to link all the required files in etc from the
host to the fhs environment, it will re-create the /etc directory.
It will do so with `0700` permissions. This causes permissions issues
with non-root programs when they need to access configuration in the
environment /etc.
By mounting /etc as a tmpfs early, bwrap will make the directory `0755`
as expected.
Some programs (e.g. nvfetcher) parse the output of nix-prefetch-git as
JSON. However, there is a pushd/popd command in nix-prefetch-git that
outputs the directory name, breaking the structure of the result JSON.
We suppressed it with `>/dev/null`.
Passingly fixes a mixuse of tab and spaces.
This script needs to support being run both as part of a `fetchgit`
derivation and as a standalone, command-line tool.
The use of `$NIX_BUILD_TOP` only works when used in `fetchgit` but not when
invoked as a standalone tool. Instead we try to respect `$NETRC` so that
the command-line invocation behaves more like standard tools and the
`fetchgit` derivation can explicitly set `$NETRC` when `netrcPhase` is used
to avoid all ambiguity.
We need this stuff to be available in lib so make-derivation.nix can
access it to construct the Meson cross file.
This has a couple of other advantages:
- It makes Rust less special. Now figuring out what Rust calls a
platform is the same as figuring out what Linux or QEMU call it.
- We can unify the schema used to define Rust targets, and the schema
used to access those values later. Just like you can set "config"
or "system" in a platform definition, and then access those same
keys on the elaborated platform, you can now set "rustcTarget" in
your crossSystem, and then access "stdenv.hostPlatform.rustcTarget"
in your code.
"rustcTarget", "rustcTargetSpec", "cargoShortTarget", and
"cargoEnvVarTarget" have the "rustc" and "cargo" prefixes because
these are not exposed to code by the compiler, and are not
standardized. The arch/os/etc. variables are all named to match the
forms in the Rust target spec JSON.
The new rust.target-family only takes a list, since we don't need to
worry about backwards compatibility when that name is used.
The old APIs are all still functional with no warning for now, so that
it's possible for external code to use a single API on both 23.05 and
23.11. We can introduce the warnings once 23.05 is EOL, and make them
hard errors when 23.11 is EOL.
Arguably, this is a bug in Nix's structuredAttrs: without
structuredAttrs, exportReferencesGraph with an empty path set would
still result in information being provided. With structuredAttrs, no
info is provided for an empty path set.
Nevertheless, we need to be able to build even if Nix has the bug, so
work around it by checking for an empty path set and handling it
explicitly.
Darwin does not actually require `*.dylib` extension, and some ports of
unix software may still simply compile and install these as `*.so` files.
Include `*.so` in the find in this case.

Rust is not yet able to target the n32 ABI on mips64.
Let's add `isMips64n32` to the `meta.badPlatforms` of all
derivations created by buildRustPackage.
I use this to automatically detect which packages on my system can
be built for n32 (almost all of them) and build those using n32, and
the few packages (mainly those that depend on boost or rust) that
can't for n64.

Before this commit, cc-wrapper/default.nix was using
`isGccArchSupported` to validate `-mtune=` values. This has two
problems:
- On x86, `-mtune=` can take the same values as `-march`, plus two
additional values `generic` and `intel` which are not valid for
`-march`.
- On ARM, `-mtune=` does not take the same values as `-march=`;
instead it takes the same values as `-mcpu`.
This commit fixes these two problems by adding a new
`isGccTuneSupported` function. For `isx86` this returns `true` for
the two special values and otherwise defers to `isGccArchSupported`.
This commit also adds support for `-mtune=` on Aarch64.
Unfortunately on Aarch64, Clang does not accept as wide a variety of
`-mtune=` values as Gcc does. In particular, Clang does not tune
for big.LITTLE mixed-model chips like the very popular RK3399, which
is targeted using `-march=cortex-a72.cortex-a53` in gcc.
To address this problem, this commit also adds a function
`findBestTuneApproximation` which can be used to map
clang-unsupported tunings like `cortex-a72.cortex-a53` to
less-precise tunings like `cortex-a53`.
The work which led to this commit arose because we now have
packages, like `crosvm`, which use *both* `clang` *and* `gcc`.
Previously I had been using `overrideAttrs` to set
`NIX_CFLAGS_COMPILE` on a package-by-package basis based on which
compiler that package used. Since we now have packages which use
*both* compilers, this strategy no longer works.
I briefly considered splitting `NIX_CFLAGS_COMPILE` into
`NIX_CFLAGS_COMPILE_GCC` and `NIX_CFLAGS_COMPILE_CLANG`, but since
`NIX_CFLAGS_COMPILE` is sort of a hack to begin with I figured that
adding the logic to `cc-wrapper` would be preferable.
Cargo will never need to link for the target platform — that'd be for
the package being built to do at runtime. Cargo should know about the
build and host linkers.
This fixes e.g. pkgsCross.musl64.fd from x86_64-linux.

This upgrade unfortunately removes MIPS support, as it has been
dropped to Tier 3[1] and so bootstrap tarballs are no longer provided.
It looks like it was dropped due to multiple codegen bugs, and lack of
maintenance, so bringing it back would probably involve engaging with
Rust/LLVM upstream on those.

So in php we have a bootstrapping composer (that lives in
composer-phar.nix) that downloads the binary distribution of composer
to be able to bootstrap and build a composer built from source.
However, it's desirable to keep composer updated at all time, and this
includes the phar one that isn't used by users directly. So this makes
sure we don't "forget" about the phar one since it now borrows the
version from the source version. However, then it also made sense to
move the hash for the phar to the same file as the source
composer. Then we can control the full upgrade life cycle of both the
phar and source versions of composer from the same file.
It's useful to have access to these attributes from packages built with
buildFHSEnvBubblewrap, and it reduces the difference between FHS and
non-FHS packages.
'name' is already handled by runCommandLocal.
This fixes a regression introduced in https://github.com/NixOS/nixpkgs/pull/256628
which broke fetching with private = true through a netrc file.
Tested locally with a really special github enterprise.
The commit 6f2b3ba027 introduced a
`mktemp` invokation that uses the `--tmpdir` flag, which is not
available on MacOS.
This changes the invokation to a portable one based on the following
StackOverflow answer https://stackoverflow.com/a/31397073/841562 .
Derivations affected by this patch set `__structuredAttrs = true;` and
provide their own `builder`, i.e. it's necessary to `source .attrs.sh`.
Rather than adding even more `if`-`source` monstrums, I decided to
modify all of those derivations to use `buildCommand` or `runCommand`,
without `builder` being set.
Then, `$stdenv/setup` is sourced already and as a result it's safe to
assume that `NIX_ATTRS_JSON_FILE`/`NIX_ATTRS_SH_FILE` point to a usable
location both in a build and a shell session.
When specifying the `builder` attribute in `stdenv.mkDerivation`, this
will be effectively transformed into
builtins.derivation {
builder = stdenv.shell;
args = [ "-e" builder ];
}
This also means that `default-builder.sh` is never sourced and as a
result it's not guaranteed that `$NIX_ATTRS_SH_FILE` is set to a correct
location[1].
Also, we need to source `.attrs.sh` to source `$stdenv`. So, the
following is done now:
* If `$NIX_ATTRS_SH_FILE` points to a correct location, then use it.
Directly using `.attrs.sh` is problematic for `nix-shell(1)` usage
(see previous commit for more context), so prefer the environment
variable if possible.
* Otherwise, if `.attrs.sh` exists, then use it. See [1] for when this
can happen.
* If neither applies, it can be assumed that `__structuredAttrs` is
turned off and thus nothing needs to be done.
[1] It's possible that it doesn't exist at all - in case of Nix 2.3 or
it can point to a wrong location on older Nix versions with a bug in
`__structuredAttrs`.

I've also exposed toRustTargetSpecShort as a public function, because
it's useful to be able to know what the target subdirectory will be.
This function helps building an OCaml package that builds with topkg.
There are currently many such packages in nixpkgs and this function
would greatly simplify adding more.
This is heavily inspired by `ocamlPackages.buildDunePackage`.
This initially may look like a downgrade, but this is caused by how
upstream is tagging versions.
Before they would have the GraalVM having its own version (e.g. 22.3.1),
and each version would support multiple JVM versions (e.g. 11, 17, 19).
Now each release supports only one JVM version (e.g.: 21), and they
track the same version as the JVM.
They also changed packaging, making all sub-products (e.g.: GraalPy,
GraalRuby, etc.) standalone, so they do not depend in GraalVM anymore
and have their own version. Thanks to this change, we will need to
repackage everything.
To simplify, this commit will remove all sub-products and only care
about the GraalVM/Native Image (that is back to GraalVM itself) part.
Other commits will re-added each sub-product.
Fix (partial): https://github.com/NixOS/nixpkgs/issues/257292
Currently there is a state of severe confusion in
pkgs/build-support/rust/hooks/ regarding host vs target; right now
there is only "host" defined, but whether it means "host" or
"target" seems to fluctuate.
This commit corrects that, ensuring that all variables come in all
three flavors (build, host, target) and are used consistently with
the nixpkgs convention.
This also fixes the cross-compilation of packages which use
`maturinBuildHook` -- hooks go in `nativeBuildInputs` and are
phase-shifted backwards by one platform, so they need to be careful
about distinguishing between build and host.
Closes#247441
