Honestly I did this in the middle of trying things and then forgot
about it, and I just don’t feel like bootstrapping the whole thing
again to drop this commit.
https://hydra.nixos.org/build/299109156
Per the release notes: https://docs.python.org/3/whatsnew/3.13.html
> Remove the PyEval_ThreadsInitialized() function, deprecated in Python 3.9. Since Python 3.7, Py_Initialize() always creates the GIL: calling PyEval_InitThreads() does nothing and PyEval_ThreadsInitialized() always returns non-zero.
Broken since at least 24.11, stuck on a version from 2018, and no
longer relevant with the new SDK pattern. A newer version is packaged
separately for the Swift compiler, so maybe it could be revived there
if people clamour for a source‐built CoreFoundation in the future.
They are not doing anything right now. This is in preparation for their
complete removal from the tree.
Note: several changes that affect the derivation inputs (e.g. removal of
references to stub paths in build instructions) were left out. They will
be cleaned up the next iteration and will require special care.
Note: this PR is a result of a mix of ugly regex (not AST) based
automation and some manual labor. For reference, the regex automation
part was hacked in: https://github.com/booxter/nix-clean-apple_sdk

Format all Nix files using the officially approved formatter,
making the CI check introduced in the previous commit succeed:
nix-build ci -A fmt.check
This is the next step of the of the [implementation](https://github.com/NixOS/nixfmt/issues/153)
of the accepted [RFC 166](https://github.com/NixOS/rfcs/pull/166).
This commit will lead to merge conflicts for a number of PRs,
up to an estimated ~1100 (~33%) among the PRs with activity in the past 2
months, but that should be lower than what it would be without the previous
[partial treewide format](https://github.com/NixOS/nixpkgs/pull/322537).
Merge conflicts caused by this commit can now automatically be resolved while rebasing using the
[auto-rebase script](8616af08d9/maintainers/scripts/auto-rebase).
If you run into any problems regarding any of this, please reach out to the
[formatting team](https://nixos.org/community/teams/formatting/) by
pinging @NixOS/nix-formatting.
Dunno if this is correct, there's other `hostPlatform.isDarwin`
conditionals which may be wrong.
Leaving the other conditionals to swift maintainers or people who are
interested in swift cross-compilation

After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.
Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.
A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.

Fail to build with ninja 1.12 when NIX_BUILD_CORES is low (Hydra or Github Actions):
```
ld: warning: directory not found for option '-L/nix/store/g9rbp9m6vs1xj4jl6b6vjb6bm8kgr107-SDKs/MacOSX10.15.sdk/usr/lib/swift'
...
ld: warning: Could not find or use auto-linked library 'swiftCompatibility56'
Undefined symbols for architecture arm64:
"__swift_FORCE_LOAD_$_swiftCompatibility56", referenced from:
__swift_FORCE_LOAD_$_swiftCompatibility56_$_Optimizer in libswiftCompilerModules-bootstrapping1.a(Optimizer.o)
...
```
Can reproduce using `nix --option cores 2 build -f . swiftPackages.swift-unwrapped`.
Until we find out the exact cause, follow [swift upstream][1], pin ninja to version
1.11.1.

Swift releases are associated with particular Darwin SDK versions. They
don’t _have_ to use that version, but it makes sense to use that version
by default. The deployment target is set to the supported Swift minimum
versions. Unlike C and C++, Swift requires you to availability
annotations, so propagating a newer SDK should be safe.
libarclite is needed to support ARC on very old deployment targets
(10.10 and older). None of these deployment targets are supported
deployment targets in nixpkgs, especially for Swift. This removes the
need to package the command-line tools executables.
Swift’s build makes a few assumptions about how the SDK is set up that
are not true anymore with the new SDK. Fix it to find the SDK at
`$SDKROOT` and copy additional stubs it needs to bootstrap.
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.
