Also begin to start work on cross compilation, though that will have to
be finished later.
The patches are based on the first version of
https://reviews.llvm.org/D99484. It's very annoying to do the
back-porting but the review has uncovered nothing super major so I'm
fine sticking with what I've got.
Beyond making the outputs work, I also strove to re-sync the packages,
as they have been drifting pointlessly apart for some time.
----
Other misc notes, highly incomplete
- lvm-config-native and llvm-config are put in `dev` because they are
tools just for build time.
- Clang no longer has an lld dep. That was introduced in
db29857eb3, but if clang needs help
finding lld when it is used we should just pass it flags / put in the
resource dir. Providing it at build time increases critical path
length for no good reason.
----
A note on `nativeCC`:
`stdenv` takes tools from the previous stage, so:
1. `pkgsBuildBuild`: `(?1, x, x)`
2. `pkgsBuildBuild.stdenv.cc`: `(?0, ?1, x)`
while:
1. `pkgsBuildBuild`: `(?1, x, x)`
2. `pkgsBuildBuild.targetPackages`: `(x, x, ?2)`
3. `pkgsBuildBuild.targetPackages.stdenv.cc`: `(?1, x, x)`
In a typical build environment the toolchain will use the value of the
MACOSX_DEPLOYMENT_TARGET environment variable to determine the version
of macOS to support. When cross compiling there are two distinct
toolchains, but they will look at this single environment variable. To
avoid contamination, we always set the equivalent command line flag
which effectively disables the toolchain's internal handling.
Prior to this change, the MACOSX_DEPLOYMENT_TARGET variable was
ignored, and the toolchains always used the Nix platform
definition (`darwinMinVersion`) unless overridden with command line
arguments.
This change restores support for MACOSX_DEPLOYMENT_TARGET, and adds
nix-specific MACOSX_DEPLOYMENT_TARGET_FOR_BUILD and
MACOSX_DEPLOYMENT_TARGET_FOR_TARGET for cross compilation.
Instead of always supplying flags, apply the flags as defaults. Use
clang's native flags instead of lifting the linker flags from binutils
with `-Wl,`.
If a project is using clang to drive linking, make clang do the right
thing with MACOSX_DEPLOYMENT_TARGET. This can be overridden by command
line arguments. This will cause modern clang to pass
`-platform_version 10.12 0.0.0`, since it doesn't know about the SDK
settings. Older versions of clang will pass down `-macos_version_min`
flags with no sdk version.
At the linker layer, apply a default value for anything left
ambiguous. If nothing is specified, pass a full
`-platform_version`. If only `-macos_version_min` is specified, then
lock down the sdk_version explicitly with `-sdk_version`. If a min
version and sdk version is passed, do nothing.
The `docker load` command supports loading tarballs that contain
multiple docker images with their respective image names and tags. This
enables distributing these images as a single file which simplifies the
release of software when an application requires multiple services to
run.
However, pkgs.dockerTools only create tarballs with a single docker
image and there exists is no mechanism in nixpkgs to combine the created
tarballs. This commit implements merging of tarballs in a way that is
compatible with `docker load`.
Since 03eaa48 added perl.withPackages, there is a canonical way to
create a perl interpreter from a list of libraries, for use in script
shebangs or generic build inputs. This method is declarative (what we
are doing is clear), produces short shebangs[1] and needs not to wrap
existing scripts.
Unfortunately there are a few exceptions that I've found:
1. Scripts that are calling perl with the -T switch. This makes perl
ignore PERL5LIB, which is what perl.withPackages is using to inform
the interpreter of the library paths.
2. Perl packages that depends on libraries in their own path. This
is not possible because perl.withPackages works at build time. The
workaround is to add `-I $out/${perl.libPrefix}` to the shebang.
In all other cases I propose to switch to perl.withPackages.

Without this fix, I can no longer build anything with releaseTools.nixBuild {}. A job typically fails with:
$ nix-build release.nix -A build.basic.x86_64-linux --show-trace
error: while evaluating the attribute 'lib' of the derivation 'libnixxml-0.1pre1234' at /home/sander/teststuff/nixpkgs/pkgs/build-support/release/nix-build.nix:89:5:
cannot coerce a set to a string, at /home/sander/teststuff/nixpkgs/pkgs/build-support/release/nix-build.nix:89:5
This is caused by the fact that `lib' is propagated as a parameter, which is a function. Functions cannot be converted to strings.
For images running on Kubernetes, there is no guarantee on how duplicate
environment variables in the image config will be handled. This seems
to be different from Docker, where the last environment variable value
is consistently selected.
The current code for `streamLayeredImage` was exploiting that assumption
to easily propagate environment variables from the base image, leaving
duplicates unchecked. It should rather resolve these duplicates to
ensure consistent behavior on Docker and Kubernetes.
It is now possible to pass a `fromImage` to `buildLayeredImage` and
`streamLayeredImage`, similar to what `buildImage` currently supports.
This will prepend the layers of the given base image to the resulting
image, while ensuring that at most `maxLayers` are used. It will also
ensure that environment variables from the base image are propagated
to the final image.
The check for including the C++ standard library headers was nested inside the
check for linking with the C++ standard library. As a result, the `-nostdlib`
flag incorrectly implied `-nostdinc++`, which made it virtually impossible to
partially link C++ objects.
runCommandWith receives an attribute set with options which previously
were positional arguments of runCommand' and a buildCommand. This
allows for overriding the used stdenv freely (so stuff like
llvmPackages.stdenv can be used). Additionally the possibility to change
arguments passed to stdenv.mkDerivation is made more explicit via the
derivationArgs argument.
Previously it was awkward to use the runCommand-variants with
passAsFile as a double definition of passAsFile would potentially
break runCommand: passAsFile would overwrite the previous definition,
defeating the purpose of setting it in runCommand in the first place.
This is now fixed by concatenating the [ "buildCommand" ] list with
one the one from env, if present.
Adjust buildEnv where passAsFile = null; was passed in some cases,
breaking evaluation since it'd evaluate to [ "buildCommand" ] ++ null.
Commit df4761 added a call to readlink, which fails if it is not in the
user's path when run. Updated the readlink call to pull from the
coreutils store path directly.
When using `buildLayeredImage`, it is not possible to specify an image
name of the form `<registry>/my/image`, although it is a valid name.
This is due to derivations under `buildLayeredImage` using that image
name as their derivation name, but slashes are not permitted in that
context.
A while ago, #13099 fixed that exact same problem in `buildImage` by
using `baseNameOf name` in derivation names instead of `name`. This
change does the same thing for `buildLayeredImage`.
`stream_layered_image.py` currently assumes that the store root will be
at `/nix/store`, although the user might have configured this
differently. This makes `buildLayeredImage` unusable with stores having
a different root, as they will fail an assertion in the python script.
This change updates that assertion to use `builtins.storeDir` as the
source of truth about where the store lives, instead of assuming
`/nix/store`.
- This is the first packages which uses Dune in order to build and install
so I had to refactor build-support/coq/default.nix in order to support it.
- I added a new feature: one can now release.v.sha256 empty to try to download
with a fake sha256, hence failures are reported and one can copy paste the
sha256 given by the error message.
- I updated the documentation of languages-frameworks/coq.section.md accordingly.
Fixes build failures with clang:
clang-7: error: unknown argument: '-fPIC -target'
clang-7: error: no such file or directory: '@<(printf %qn -O2'

Introduced by 60c5cf9cea in #112449
Since #112276, we should always put `makeWrapper` in
`nativeBuildInputs`. But `buildEnv` was saying put it in `buildInputs`.
That's wrong!
Fix the instructions, and make the right thing possible.
The `checkType` argument of buildRustPackage was not used anymore
since the refactoring of `buildRustPackage` into hooks. This was
an oversight that is fixed by this change.
The check type can also be passed directly to cargoCheckHook using the
`cargoCheckType` environment variable.
This change makes the wrapper script avoid displaying echo area messages
during startup. This helps prevent split second UI glitches early in the
startup process. The messages itself will still be logged and therefore
will not hamper inspection for debugging purposes.
Preserve top-level symlinks such as /lib -> /usr/lib.
This allows nested containers such as Steam's new runtime to remount
/usr if they need to and then run unmodified binaries that reference
e.g. /lib/ld-linux-x86-64.so.2
Before, we would mount the fully resolved host directory at /lib and
thus the dynamic loader would always be the one from the host filesystem.
The reason for this change is simply to avoid the following messages
that are unnecessary and can be confusing (and these messages will be
repeated for each submodule):
hint: Using 'master' as the name for the initial branch. This default branch name
hint: is subject to change. To configure the initial branch name to use in all
hint: of your new repositories, which will suppress this warning, call:
hint:
hint: git config --global init.defaultBranch <name>
hint:
hint: Names commonly chosen instead of 'master' are 'main', 'trunk' and
hint: 'development'. The just-created branch can be renamed via this command:
hint:
hint: git branch -m <name>
With this change the behaviour remains unchanged (apart from the
suppressed "warning" in the console output of course) and therefore this
doesn't cause any hashes to change and by default nix-prefetch-git uses
the "fetchgit" branch anyway (branchName can be set to override the
default):
Switched to a new branch 'fetchgit'
For that reason the initial branch name doesn't matter anyway and since
we're not relying on / hardcoding "master" we could simply switch to
"main" (which seems most common nowadays). See [0] for more details on
why this wouldn't break anything.
However, since the initial branch name doesn't matter and to avoid any
additional risks it was "decided" to keep using "master" (s. #113313).

API change:
`cargoParallelTestThreads` suggests that this attribute sets the
number of threads used during tests, while it is actually a boolean
option (use 1 thread or NIX_BUILD_CORES threads). In the hook, this
is replaced by a more canonical name `dontUseCargoParallelTests`.
The directory in the tarball of vendored dependencies contains `name`,
which is by default set to `${pname}-${version}`. This adds an
additional attribute to permit setting the name to something of the
user's choosing.
Since `cargoSha256`/`cargoHash` depend on the name of the directory of
vendored dependencies, `cargoDepsName` can be used to e.g. make the
hash invariant to the package version by setting `cargoDepsName =
pname`.
The previous commit stopped systemd from looking for system units in
/etc/systemd-mutable/system, which was a Dysnomia-specific path.
While this script doesn't seem to be used anywhere inside nixpkgs (also
not in the gone-since #110799 Dysnomia), its fallback mode (when
/etc/systemd/system is read-only) did write units to that
Dysnomia-specific path, which systemd now doesn't look at anymore.
It might be up for another debate on whether systems with read-only
/etc/systemd/system should probably just use /run/systemd/system, and
not some NixOS-specific paths, as such conditions can happen on other
distros too, but let's pick the other NixOS-specific path
/nix/var/nix/profiles/default/lib/systemd/system for now, which is
probably better than a path that surely is never looked at.
- API change: remove the `target` argument of `buildRustPackage`, the
target should always be in sync with the C/C++ compiler that is used.
- Gathering of binaries has moved from `buildPhase` to `installPhase`,
this simplifies the hook and orders this functionality logically
with the installation logic.
This caused shebangs that were already store paths to be rewritten.

/usr/bin/env seems to be no longer be present in the sandbox. This means
that fetchcvs would fail with a “not found error” whenever CVS_RSH was
necessary.
We fix this by simply setting the current $SHELL as shebang.
Alternatively also setting it to /bin/sh statically would be possible.
4a5c49363a added some more commands after
`extraPostFetch` but concatenated them without a separating newline.
Which means, that since that commit
fetchzip { ..., extraPostFetch = ''rm -f "$out"/some-file''; }
now actually runs the following shell command
rm -f "$out"/some-file"chmod -R a-w "$out"
thus deleting "$out". Which is very unfortunate.
Especially since this actually happens on master for all `fetchFromBitbucket`
derivations. But since the results are fixed-output users bulding with hydra
cache enabled are not hitting this for not recently updated derivations yet.
The Everthing module is not part of a library and should therefore
not be copied to the nix store.
This is particularly bad, if the Everything module is defined in
an agda library included directory, e.g. consider an agda-lib with
include: .
and Everything.agda in the project root (.), in which case the
Everything module would become part of the library.
If multiple such projects are in the dependency tree, the Everything
module becomes ambiguous and the build would fail.
The `platform` field is pointless nesting: it's just stuff that happens
to be defined together, and that should be an implementation detail.
This instead makes `linux-kernel` and `gcc` top level fields in platform
configs. They join `rustc` there [all are optional], which was put there
and not in `platform` in anticipation of a change like this.
`linux-kernel.arch` in particular also becomes `linuxArch`, to match the
other `*Arch`es.
The next step after is this to combine the *specific* machines from
`lib.systems.platforms` with `lib.systems.examples`, keeping just the
"multiplatform" ones for defaulting.
continuation of #109595
pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
Since fdf32154fc, we no longer allow
missing modules in the initrd. Unfortunately since before this commit,
the modules-closure script would also fail on missing firmware, which
is a very common case (e.g. xhci-pci.ko.xz lists renesas_usb_fw.mem as
dependent firmware). Fix this by only issuing a warning instead.
This was already fixed on non-Darwin, but the fix missed that it was
also reintroduced for the Darwin code path at the same time.

Warning about future breaking changes is wrong.
- It suggests that the maintainers don't value backwards compatibility.
They do.
- It implies that other parts of Nixpkgs won't ever break. They will.
- It implies that a well-defined "public" interface exists. It doesn't.
- If the reasons above didn't apply, it should have been in the manual
instead.
Breaking changes will come, especially to the interface. That can be the
only way we can make progress without breaking the image _contents_.
I don't think dockerTools is any different from most of Nixpkgs in
these regards.
