- 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: 'x86_64-apple-darwin'
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.

Example difference:
$ echo "hello world" | tail -c+3
llo world
$ str="hello world"; echo ${str:3}
lo world
/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.
`buildRustPackage` currently accepts `cargoSha256` as a hash for
vendored dependencies. This change adds `cargoHash` which accepts SRI
hashes, setting `outputHashAlgo` to `null`.
The hash mismatch message still uses `cargoSha256` as an example,
which it probably should until we completely switch to SRI hashes.
By default, Perl versions since 5.8.1 use randomization to make hashes
resistant to complexity attacks.
That randomization makes building VM images such as ubuntu1804x86_64
non-deterministic because the (imported) derivations built by
deb/deb-closure.pl are not stable.
This can easily be observed by repeating the following sequence of
commands and noting the path of the image's .drv:
nix-instantiate -E '(import <nixpkgs> {}).vmTools.diskImageFuns.ubuntu1804x86_64 {}'
nix-store --delete /nix/store/*ubuntu-18.04-bionic-amd64.nix
One source of non-determinism is the handling of Provides/Replaces,
which depends on the order of iteration over %packages. Here is a
diff showing the corresponding change in output:
>>> awk
-virtual awk: using original-awk
- original-awk: libc6 (>= 2.14)
+virtual awk: using mawk
+ mawk: libc6 (>= 2.14)
- mawk: libc6 (>= 2.14)
->>> libc6
This patch sorts packages by name for Provides/Replaces processing,
which seems to result in stable output.
(If the above turns out not to be sufficient, one could also set the
PERL_HASH_SEED and PERL_PERTURB_KEYS environment variables, documented
in 'perlrun', to disable Perl's built-in randomization. Complexity
attacks are not an issue as we control and trust all inputs.)
Using the full store hash as the random seed occasionally caused
reference cycles when the invocation was stored in output artifacts.
For example, cross-compiled gcc was failing due to this:
https://hydra.nixos.org/eval/1631713#tabs-now-fail
Simply truncating the hash is sufficient to avoid this.
When invoking a simple Ada program with `gcc` from `gnats10`, the
following warnings are shown:
```
$ gcc -c conftest.adb
gnat1: warning: command-line option ‘-Wformat=1’ is valid for C/C++/ObjC/ObjC++ but not for Ada
gnat1: warning: command-line option ‘-Wformat-security’ is valid for C/C++/ObjC/ObjC++ but not for Ada
gnat1: warning: ‘-Werror=’ argument ‘-Werror=format-security’ is not valid for Ada
$ echo $?
0
```
This is only spammy when compiling Ada programs inside a Nix derivation,
but certain configure scripts (such as the ./configure script from the
gcc that's built by coreboot's `make crossgcc` command) fail entirely
when getting that warning output.
https://nixos.wiki/wiki/Coreboot currently suggests manually running
> NIX_HARDENING_ENABLE="${NIX_HARDENING_ENABLE/ format/}" make crossgcc
… but actually teaching the nixpkgs-provided cc wrapper that `format`
isn't supported as a hardening flag seems to be the more canonical way
to do this in nixpgks.
After this, Ada programs still compile:
```
$ gcc -c conftest.adb
$ echo $?
0
```
And the compiler output is empty.
As @lopsided98 points out in #105305, since the hashes are now target
sensative, and until we find reason to actually care to test what they
are exactly, we are best just normalizing them away in the tests.
- Generate a link to the initramfs file with an appropriate file
extension, guessed based on the compressor by default
- Use correct metadata in u-boot images if generated, up to now this
was hardcoded to gzip and would silently generate an erroneous image
if another compressor was specified
- Document all the parameters
- Improve cross-building compatibility, by allowing passing either a
string as before, or a function taking a package set and returning the
path to a compressor in the "compressor" argument of the
function.
- Support more compression algorithms
- Place compressor executable function and arguments in passthru, for
reuse when appending initramfses
