Fixes#49071
On ld.gold, we produce broken executables when linking with the Musl
libc. This appears to be a known bug when using ld.gold and Musl. This
thread describes the workaround as enabling PIE when using ld.gold and
Musl:
https://www.openwall.com/lists/musl/2015/05/01/5
By default we don’t enable PIE to avoid breaking things. But in the
Musl case we are breaking things by not enabling PIE. So this adds a
special case for defaultHardeningFlags which keeps the pie hardening
for everything. Any packages that break with PIE can add the pie flag
to disableHardeningFlags array (a no-op for now on anything but Musl).
Rationale
---------
Currently, tests are hard to discover. For instance, someone updating
`dovecot` might not notice that the interaction of `dovecot` with
`opensmtpd` is handled in the `opensmtpd.nix` test.
And even for someone updating `opensmtpd`, it requires manual work to go
check in `nixos/tests` whether there is actually a test, especially
given not so many packages in `nixpkgs` have tests and this is thus most
of the time useless.
Finally, for the reviewer, it is much easier to check that the “Tested
via one or more NixOS test(s)” has been checked if the file modified
already includes the list of relevant tests.
Implementation
--------------
Currently, this commit only adds the metadata in the package. Each
element of the `meta.tests` attribute is a derivation that, when it
builds successfully, means the test has passed (ie. following the same
convention as NixOS tests).
Future Work
-----------
In the future, the tools could be made aware of this `meta.tests`
attribute, and for instance a `--with-tests` could be added to
`nix-build` so that it also builds all the tests. Or a `--without-tests`
to build without all the tests. @Profpatsch described in his NixCon talk
such systems.
Another thing that would help in the future would be the possibility to
reasonably easily have cross-derivation nix tests without the whole
NixOS VM stack. @7c6f434c already proposed such a system.
This RFC currently handles none of these concerns. Only the addition of
`meta.tests` as metadata to be used by maintainers to remember to run
relevant tests.
Uses uname data to find what to set these variables:
- CMAKE_SYSTEM_NAME
- CMAKE_SYSTEM_PROCESSOR
- CMAKE_SYSTEM_VERSION
- CMAKE_HOST_SYSTEM_NAME
- CMAKE_HOST_SYSTEM_PROCESSOR
- CMAKE_HOST_SYSTEM_VERSION
The isELF function only checks whether ELF is contained within the first
4 bytes of the file, which is a bit fuzzy and will also return
successful if it's a text file starting with ELF, for example:
ELF headers
-----------
Some text here about ELF headers...
So instead, we're now doing a precise match on \x7fELF.

The `unfree` and `unfreeRedistributable` licenses both have `free = false`,
which will trigger the first portion of logic. This removes dead code to
simplify the logic.
As a follow-up, I plan to add an attribute `redistributable = [true|false]`,
which can be used by Hydra to determine whether a given package with a given
license can be included in the channel.
If meta.outputsToInstall is set to include absent outputs, various
tools break including channel updates and nix-env.
grahamc@Morbo> nix-env -i -f . -A elf-header-real
installing 'elf-header'
error: this derivation has bad 'meta.outputsToInstall'
This patch verifies each value in meta.outputsToInstall is a valid
output. It validates this condition only if checkMeta is true.
grahamc@Morbo> nix-build . -A elf-header-real
error: Package ‘elf-header’ in /home/grahamc/projects/nixpkgs/pkgs/development/libraries/elf-header/default.nix:36 has invalid meta.outputsToInstall, refusing to evaluate.
The package elf-header has set meta.outputsToInstall to: bin
however elf-header only has the outputs: out
and is missing the following ouputs:
- bin
(use '--show-trace' to show detailed location information)
Note, now the nix-env experience is decidedly worse for users who have
checkMeta set to true:
grahamc@Morbo> nix-env -i -f . -A elf-header-real; echo $?
0
though since this is already an issue for unfree, broken, unsupported,
and insecure validity problems I'm not sure we should do something
different here.
a4630c65ca was incorrect in assuming $SHELL would be a path to the
bash derivation. In fact $SHELL will be a path to the bash executable.
Unfortunately this did not fix the original issue. So instead, we just
have to reuse initialPath can be added like PATH is.
Sorry for the inconvenience! I hadn’t thought through the effects of
the last commit.

To avoid breaking things, we need to make sure SHELL goes into
HOST_PATH. This reflects my changes to patch-shebangs to make it cross
compilation ready. When a script is patched from the Nix store it now
looks to HOST_PATH to get the targeted machine’s executables.
Unfortunately, this only works in native builds.
Intuitively, one cares mainly about the host platform: Platforms differ
in meaningful ways but compilation is morally a pure process and
probably doesn't care, or those difference are already abstracted away.
@Dezgeg also empirically confirmed that > 95% of checks are indeed of
the host platform.
Yet these attributes in the old cross infrastructure were defined to be
the build platform, for expediency. And this was never before changed.
(For native builds build and host coincide, so it isn't clear what the
intention was.)
Fixing this doesn't affect native builds, since again they coincide. It
also doesn't affect cross builds of anything in Nixpkgs, as these are no
longer used. It could affect external cross builds, but I deem that
unlikely as anyone thinking about cross would use more explicit
attributes for clarity, all the more so because the rarity of inspecting
the build platform.
Works similarly to `enableParallelBuilding`, but is set by default when
`enableParallelBuilding` is set. In my experience most packages that build
fine in parallel also check fine in parallel.
Derivations where drawing their `system` attribute from `hostPlatform`
instead of `buildPlatform`. Fix that, and add an explanatory commment.
Fixes#45993
This has been not touched in 6 years. Let's remove it to cause less
problems when adding new cross-compiling infrastructure.
This also simplify gcc significantly.
I *want* cross-specific overrides to be verbose, so I rather not have
this shorthand. This makes the syntactic overhead more proportional to
the maintainence cost. Hopefully this pushes people towards fewer
conditionals and more abstractions.

With meson 0.47.0 (or 0.47.1, or git)
things are very wrong re:rpath handling
resulting in at best missing libs but
even corrupt binaries :(.
When we run patchelf it masks the problem
by removing obviously busted paths.
Which is probably why this wasn't noticed immediately.
Unfortunately the binary already
has a long series of paths scribbled
in a space intended for a much smaller string;
in my testing it was something like
lengths were 67 with 300+ written to it.
I think we've reported the relevant issues upstream,
but unfortunately it appears our patches
are what introduces the overwrite/corruption
(by no longer being correct in what they assume)
This doesn't look so bad to fix but it's
not something I can spend more time on
at the moment.
--
Interestingly the overwritten string data
(because it is scribbled past the bounds)
remains in the binary and is why we're suddenly
seeing unexpected references in various builds
-- notably this is is the reason we're
seeing the "extra-utils" breakage
that entirely crippled NixOS on master
(and probably on staging before?).
Fixes#43650.

`depsHostBuild` is not a thing, would never be a thing per the rules,
and isn't used anywhere. This is just my typo, hitherto unnoticed
because "host -> host" dependencies are by far the most obscure form.
HOST_PATH contains the path of the host package. This will include the
packages listed in buildInputs & depsHostHost. Use this to find
runtime commands that the host needs.
For instance to find the runtime version of perl,
$ PATH="$HOST_PATH" command -v perl
/nix/store/...-perl-5.28.0-aarch64-unknown-linux-android/bin/perl
This path should not be executed directly (it will break for cross
compilation). Only use it to find the location of executables that
will be run by your host system. Your build tools will, as always, be
available on the default PATH.
The line was essentially checking whether /bin/sh exists and is
executable and if that's the case, the isScript function returns
successfully.
When asking the author of this line on IRC it seems that even they can't
remember or imagine what this was supposed to be.
In summary: Whenever /bin/sh doesn't exist during a build, *any* file
given to isScript is reported as being a script even if it isn't.
This is kinda counter-intuitive and not something what somebody would
expect from a function called "isScript".

Not only does the suffix unnecessarily reduce sharing, but it also breaks
unpacker setup hooks (e.g. that of `unzip`) which identify interesting tarballs
using the file extension.
This also means we can get rid of the splicing hacks for fetchers.
We want `buildPackages` to be almost the same as
`buildPackages.buildPackges`, but that is only true if most packages
don't care about the target platform. The commented code however made
them all care about whether the target platform was Darwin.
The hack of using `crossConfig` to enforce stricter handling of
dependencies is replaced with a dedicated `strictDeps` for that purpose.
(Experience has shown that my punning was a terrible idea that made more
difficult and embarrising to teach teach.)
Now that is is clear, a few packages now use `strictDeps`, to fix
various bugs:
- bintools-wrapper and cc-wrapper
Note that a bunch of non-python packages use this attribute already.
Some of those are clearly unaware of the fact that this attribute does
not exists in stdenv because they define it but don't to add it to
their `bulidInputs` :)
Also note that I use `buildInputs` here and only handle regular
builds because python and haskell builders do it this way and I'm not
sure how to properly handle the cross-compilation case.
