Ada depencencies musst be build with the same gnat version as the
project. Use a namespace as preperation to build with different gnat
versions.
gprbuild and gnatprove are still globaly visable.
this equates to -ftrivial-auto-var-init=pattern
clang has removed support for -ftrivial-auto-var-init=zero and
are unlikely to re-add it, so use -ftrivial-auto-var-init=pattern
on both compilers if only to make behaviour more consistent
between the two.
add to pkgsExtraHardening's defaultHardeningFlags.
The loaded database contains timestamps of when the nix paths were
registered. Depending on the host store, these can differ between runs.
Resetting them to a well known values ensures that the produced image is
reproducible.
This commit adds support for swapping out the compression algorithm
used in all major docker-tools commands that generate images. The
default algorithm remains unchanged (gzip).
This fetcher is to be used with PyPi mirrors exposing the "legacy" API, such as devpi.
A variant of this fetcher has been used in poetry2nix for years and
has served us well there to support private PyPi mirrors and Devpi.
Example usage:
``` nix
fetchPypiLegacy {
file = "urllib3-1.26.2.tar.gz";
hash = "sha256:19188f96923873c92ccb987120ec4acaa12f0461fa9ce5d3d0772bc965a39e08";
pname = "urllib3";
url = "https://pypi.org/simple";
}
```

Let's always produce empty output for zero-modules tests.
The previous version didn't work in the case of relative symlinks in
subdirectories. If "foo/bar" was a link to "baz", it would check for
a link to "baz" in the root, rather than under "foo".
We don't need to dereference the symlink ourselves for [ anyway, as it
dereferences its arguments itself, so all we need to do to fix this is
to pass it the link.
Fixes: 14f83d5c6f ("compressFirmwareXz: fix links to directories")
`multiPaths` is defined via invalid operation on `null` value for
non-multilib environments. Noticed on `notesnook` evan failure as:
nix-repl> notesnook.fhsenv.multiPaths
253| passthru = {
254| inherit args baseTargetPaths targetPaths baseMultiPaths multiPaths ldconfig;
| ^
255| };
error: attempt to call something which is not a function but null
The change makes `multiPaths` a private variable.
The unwrapped version doesn't know where to look for libraries, so
this is required to e.g. build anything that uses openssl-sys with
OPENSSL_NO_VENDOR. A randomly chosen example package that's fixed by
this change is pkgsStatic.gitoxide.
We're already using pkgsBuildBuild, and we'll soon be using
pkgsBuildTarget, so for consistency, change buildPackages and
targetPackages to their corresponding two-component names.
Pass the whole environment to the native-image build process by
generating a -E option for every environment variable.
This has the same effect as setting
NATIVE_IMAGE_DEPRECATED_BUILDER_SANITATION=true
but is compatible with packages providing -E options themselves
Packages that require access to environment variables in the build
should specify these using `-E` arguments in `nativeImageBuildArgs` or
using a `native-image.properties` as described here:
https://www.graalvm.org/22.1/reference-manual/native-image/BuildConfiguration/#embedding-a-configuration-file
Specifying NATIVE_IMAGE_DEPRECATED_BUILDER_SANITATION=true breaks with
packages that list their environment variables explicitly in `native-image.properties`.
this allows a compiler derivation to provide a
hardeningUnsupportedFlagsByTargetPlatform passthru attr
that will be called with the targetPlatform to determine
the unsupported hardening flags for that platform.
we can do this because even though a clang compiler is
multi-target by nature, cc-wrapper effectively fixes the
target platform at wrapping time. otherwise we'd have to
sniff the intended target at runtime, which wouldn't
be fun at all.
the advantage of using a new attribute instead of
allowing hardeningUnsupportedFlags to optionally be a
function is that hardeningUnsupportedFlags retains its
simple overriding pattern for simple cases (i.e.
`(prev.hardeningUnsupportedFlags or []) ++ [ "foo" ]`
) which will continue to work as long as the bottom-most
function of hardeningUnsupportedFlagsByTargetPlatform
falls back to hardeningUnsupportedFlags.
PR #275947, which was self-merged without approvals, inserted
functionality specific to a propriteary closed-source compiler
(CUDA) into cc-wrapper.
This commit relocates this CUDA-specific functionality into the
appropritate place: `cuda-modules`.
It is unclear to me exactly what this function is supposed to be
doing; much of it (like the `.kind` attributes) do not appear to be
used *anywhere* in nixpkgs. Making sure we don't insert unexplained
deadcode like this is one of the important functions of the review
process.
This commit deletes speculative comments which were self-merged with
no approvals in PR #275947.
If you think that "The above 'fix' may be incorrect" the correct
response is to submit a PR which removes the 'fix' and get it reviewed.
Likewise, if you think that "For clang it's not necessary" you
should submit a PR which wraps it in `if !isClang`.
`cc-wrapper` is full of too much junk as it is, let's not make
things worse.
The commit prior to this one, "gcc: fix c++ headers when same
triplet cross compiling" causes gcc's c++ headers to be in the same
outpath subdirectory regardless of whether the gcc build is a
host==target or host!=target compiler.
As a result of that change, the hack in cc-wrapper which adapted to
the different paths is no longer needed. And, in fact, it must be
removed, since if it is left in place builds such as
pkgsCross.aarch64-multiplatform.firefox will fail as shown below.
