Previously, when sha256 either wasn't defined or set to an empty string
fetchpatch would error out as follows:
'''
warning: found empty hash, assuming 'sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA='
...
/nix/store/agwlk2bcfvz2ggrsbvwd7696qj55frbi-stdenv-linux/setup: line 96: /build/: Is a directory
sed: couldn't flush stdout: Broken pipe
'''
This patch makes it show fetchurl's error message instead:
'''
warning: found empty hash, assuming 'sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA='
...
error: hash mismatch in fixed-output derivation:
specified: sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
got: sha256-NWGWoyEgT/ztCwbhNgGPvG+nqX4bxtFnD+wds6fklbs=
'''
This is very convenient for TOFU.

This is useful for a use-case we have with a Nix-based CI system that
specifies things like deploy steps as passthru attributes[0].
Previously the only way to do this would have been to concatenate
attributes onto the resulting derivation, but passing them in and
actually treating them as proper passthru attributes is cleaner.

This was pretty straightforward, note that go1.17 is explicitly required
by v0.5.1, and one of the tests requires git, so I added it to the
checkInputs.
Also the tests now pass and don't need the mangle, so I removed the
patch. I left the darwin/aarch64 patch in.
The `nix.*` options, apart from options for setting up the
daemon itself, currently provide a lot of setting mappings
for the Nix daemon configuration. The scope of the mapping yields
convience, but the line where an option is considered essential
is blurry. For instance, the `extra-sandbox-paths` mapping is
provided without its primary consumer, and the corresponding
`sandbox-paths` option is also not mapped.
The current system increases the maintenance burden as maintainers have to
closely follow upstream changes. In this case, there are two state versions
of Nix which have to be maintained collectively, with different options
avaliable.
This commit aims to following the standard outlined in RFC 42[1] to
implement a structural setting pattern. The Nix configuration is encoded
at its core as key-value pairs which maps nicely to attribute sets, making
it feasible to express in the Nix language itself. Some existing options are
kept such as `buildMachines` and `registry` which present a simplified interface
to managing the respective settings. The interface is exposed as `nix.settings`.
Legacy configurations are mapped to their corresponding options under `nix.settings`
for backwards compatibility.
Various options settings in other nixos modules and relevant tests have been
updated to use structural setting for consistency.
The generation and validation of the configration file has been modified to
use `writeTextFile` instead of `runCommand` for clarity. Note that validation
is now mandatory as strict checking of options has been pushed down to the
derivation level due to freeformType consuming unmatched options. Furthermore,
validation can not occur when cross-compiling due to current limitations.
A new option `publicHostKey` was added to the `buildMachines`
submodule corresponding to the base64 encoded public host key settings
exposed in the builder syntax. The build machine generation was subsequently
rewritten to use `concatStringsSep` for better performance by grouping
concatenations.

When I designed `mkShell`, I didn't have a good idea of what the output
should look like and so decided to make the build fail. In practice,
this causes quite a bit of confusion and complications because now the
shell cannot be part of a normal package set without failing the CI as
well.
This commit changes that build phase to record all the build inputs in a
file. That way it becomes possible to build it, makes sure that all the
build inputs get built as well, and also can be used as a GC root.
(by applying the same trick as #95536).
The documentation has also been improved to better describe what mkShell
does and how to use it.
macOS's dyld can be rather picky as to what dylib it accepts. This
even changes across macOS versions. Therefore we now build a fat
dylib with all three architectures (x86_64, arm64, arm64e). This
should then be compatible with pretty much any macOS's dyld.
The tools built with buildGraalVmNativeImage have broken UTF-8 support
when not properly setting the locale, e.g.
$ bb -e '(prn "bépo àê")'
"b??po ????"
This commit sets the locale to en_US.UTF-8 by default, which fixes that.
