This is some thing introduced in 2017 to work around a problem that
no longer seems to exist. Nothing uses it except its own test, which
these days passes even with the standard `clangStdenv`.
This adds convenience writers for self-contained Nim programs.
Those are compiled into very small binaries.
Test with: `nix build .#pkgs.tests.writers.{bin,simple,wrapping}.nim`
`makeWrapper` is often used in these with `source "${makeWrapper}/nix-support/setup-hook"`
which causes `error: makeWrapper/makeShellWrapper must be in nativeBuildInputs` on cross.
Prior to this commit it was not possible to modify e.g. the list of ignored directories at all, however given that `buildFHSEnvBubblewrap` effectively uses a sandboxing tool (*bwrap*) I feel like this is a missed opportunity.
The code in nixpkgs already covers all the knobs that are required to get *Nix* itself to run inside bubblewrap, so why not allow users to make that additional modification?
While additional `ro_mounts` and such can be *added* to the bubblewrap invocation, the already mounted directories cannot be removed, and even if shadowed by e.g. a tmpfs mount, this would still allow something inside the sandbox to potentially unmount the tmpfs and access the data.
So what this change does is moving the snippet where custom code can be injected down by four lines so that users can actually modify those variables e.g. using `ignored+=( /home /srv /mnt /boot )`.
The only cases in which this would break is:
- someone using those variable names in `extraPreBwrapCmds` already and relying on them being overwritten; I would consider that chance slim, and the fix would be easy enough
- someone using a construct like `false && \` to disable the `ignored` initialisation and effectively working around this limitation; again the chances are slim (even though I know I'd be affected), and the fix would be easy enough (as this change makes the workaround needless anyway so it's an improvement)

Setting the image creation timestamp in the image metadata to a
constant date can cause problems with self-hosted container
registries, that need to e.g. prune old images. This timestamp is
also useful for debugging.
However, it is almost never useful to set the filesystem timestamp to
a constant value. Doing so not only causes the image to possibly no
longer be reproducible, but also removes any possibility of
deduplicating layers with other images, causing unnecessary storage
space usage.
Therefore, this commit introduces "mtime", a new parameter to
streamLayeredImage, which allows specifying the filesystem timestamps
separately from "created". For backwards compatibility, "mtime"
defaults to the value of "created".
In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

To prevent excessive build times when replacement lists are shared between
partially overlapping closures, skip the build of unused replacements.
Unfortunately, this also means that the replacement won't be applied any more
if another replacement that is applied introduces its source. But this is a
corner case, and we already show a warning, so make it clearer that handling
this situation (should it ever arise) is the responsibility of the user.
Unlike regular input-addressed or fixed-output derivations, floating and
deferred derivations do not have their store path available at evaluation time,
so their outPath is a placeholder. The following changes are needed for
replaceDependencies to continue working:
* Detect the placeholder and retrieve the store path using another IFD hack
when collecting the rewrite plan.
* Try to obtain the derivation name needed for replaceDirectDependencies from
the derivation arguments if a placeholder is detected.
* Move the length mismatch detection to build time, since the placeholder has a
fixed length which is unrelated to the store path.
Rewrite replaceDependency so that it can apply multiple replacements in
one go. This includes correctly handling the case where one of the
replacements itself needs to have another replacement applied as well.
This rewritten function is now aptly called replaceDependencies.
For compatibility, replaceDependency is retained as a simple wrapper
over replaceDependencies. It will cause a rebuild because the unpatched
dependency is now referenced by derivation instead of by storePath, but
the functionality is equivalent.

This make sure the credentials cannot be leaked in a MITM attack.
Note that this change might break some existing deployments if the users
tries to fetch resources on endpoints with invalid certificates.
The impacted users will have the following choices:
* fix the endpoint providing the resource
* override SSL_CERT_FILE to either disable the verification (not
recommended) or to set it to a path including their CA certificate.
Previously running the Bitwarden AppImage would error.
This adds libsecret which resolves the error and allows the
Bitwarden AppImage to function normally.
This patch adds an assertion to the writeTextFile trivial
builder, asserting that a specified destination starts with
a slash.
This matches the current behavior of the function and merely
provides a helpful error message.
The dotnet sdk used usually needs to match the one required by the
project (global.json). Having the dependcy in nix just meant it always
had to be overridden.
Rationale:
With the advent of RFC 140, Nixpkgs becomes to promote self-contained package
directories and strongly discourages scattering along the old and deprecated
filesystem hierarchy.
Further, `build-support/flutter/*` is not referenced by any other expressions in
Nixpkgs besides flutter itself.
Further, concentrating all Flutter-related toolset below a same directory
hierarchy (arguably?) eases maintenance and future migrations.
Seeing the following new warnings pop up on stderr when cargo was bumped
to 1.78:
```
warning: `/build/.cargo/config` is deprecated in favor of `config.toml`
note: if you need to support cargo 1.38 or earlier, you can symlink `config` to `config.toml`
```
which happens to break commitmsgfmt builds in nix (#320294).

Tested the following packages with and without structuredAttrs:
- rust-analyzer: cargo-build-hook, cargo-check-hook
- jujutsu: cargo-nextest-hook
- kornia-rs: maturin-build-hook
For a long time, we've had `crossLibcStdenv`, `*Cross` libc attributes,
and `*bsdCross` pre-libc package sets. This was always bad because
having "cross" things is "not declarative": the naming doesn't reflect
what packages *need* but rather how we *provide* something. This is
ugly, and creates needless friction between cross and native building.
Now, almost all of these `*Cross` attributes are gone: just these are
kept:
- Glibc's and Musl's are kept, because those packages are widely used
and I didn't want to risk changing the native builds of those at this
time.
- generic `libcCross`, `theadsCross`, and friends, because these relate
to the convolulted GCC bootstrap which still needs to be redone.
The BSD and obscure Linux or freestnanding libcs have conversely all
been made to use a new `stdenvNoLibc`, which is like the old
`crossLibcStdenv` except:
1. It usable for native and cross alike
2. It named according to what it *is* ("a standard environment without
libc but with a C compiler"), rather than some non-compositional
jargon ("the stdenv used for building libc when cross compiling",
yuck).
I should have done this change long ago, but I was stymied because of
"infinite recursions". The problem was that in too many cases we are
overriding `stdenv` to *remove* things we don't need, and this risks
cyles since those more minimal stdenvs are used to build things in the
more maximal stdenvs.
The solution is to pass `stage.nix` `stdenvNoCC`, so we can override to
*build up* rather than *tear down*. For now, the full `stdenv` is also
passed, so I don't need to change the native bootstraps, but I can see
this changing as we make things more uniform and clean those up.

I broke the usage of buildRustCrate with a toolchain from rust-overlay
when I added support for wasm32-unknown-unknown, this change adds
additional conditionals to restore the usage.
The toolchain can now be overriden either through
```
buildRustCrate {
rust = toolchain;
cargo = toolchain
}
```
or
```
buildRustCrate.override {
rustc = toolchain;
cargo = toolchain;
}
```
They should now be consistent with each other.
- stop binding attributes we don't care about (e.g. name, doCheck)
- remove attributes we handle in nix (e.g. useAppHost)
- inherit attributes with default values (e.g. packNupkg)
Unpacking to the build root was a bad idea. stdenv uses dumpVars() to
create a file env-vars containing the entire environment. This was
being installed in the derivation output, and since it contains lots of
store paths, it was bloating the closure for every nuget package.
After this change, enableParallelBuilding defaults to true for packages
using buildDotnetModule. The argument value already defaults to true,
but we did not use it. Note that default values in Nix are not present
in the arguments attribute set, e.g. `args` does not contain `def` for
`{ def ? true }@args: …` function unless this argument is explicitly
passed.
Previously, it wasn't possible to access the list of platforms we can
build Rust programs for outside of buildRustPackage. This was a
problem for packages that have optional Rust components, like
gstreamer or Meson, as there was no way to only build the Rust parts
for supported platforms. Now it's possible to get that information
from rustc's passthru.
