Darwin Updates News

As a follow up to Darwin Updates News - #6 by reckenrode, libiconv has been updated for Darwin to libiconv-99, which matches the version of libiconv shipped in macOS 14.4. Updating Apple’s libiconv was necessary because of the need for the special, Mac-specific UTF-8 encoding. This libiconv implementation is based on the one from FreeBSD.

In addition to the libiconv update, three packages have been introduced that may be of interest to FreeBSD users: ATF, Kyua, and Lutok. The versions of these packages in nixpkgs should correspond to the current versions in the FreeBSD ports tree.

## Description of changes This is another attempt at https://github.com/NixOS…/nixpkgs/pull/299613. The reasoning behind https://github.com/NixOS/nixpkgs/pull/238993 turned out to be mistaken. In the time between that PR and today, Apple has made several source releases. As it turns out, they switched their libiconv implementation from GNU libiconv to the implementation in FreeBSD’s libc. Updating libiconv proved to be non-trivial for a few reasons. * Upstream bugs. Apple’s implementation had bugs that caused libarchive test failures (leading to my adding a test case as I was working on diagnosing before a source release on Monday included a fix); * Build system issues. xcbuild cannot build libiconv correctly. The install names are a mess. It doesn’t handle tests are installation. Fixing would require relinking or hacking up the Xcode build project; and * Packaging ATF, Kyua, and Lutok. These are requirements for libiconv’s tests. They also mutually depend upon each other and have had releases in years. I opted to pin them to the same commits that FreeBSD’s ports does. Fortunately, those issues were solvable and should not be an issue for updates going forward. libiconv now has a test suite, and the work to make the other dependencies build should be a one time cost for packaging them. I built for both aarch64-darwin and x86_64-darwin, and I confirmed that libarchive and libgit2 build and pass their tests. The Linux builds were done on ATF, Kyua, and Lutok. I tried to build libiconv-darwin on Linux, but it failed. It may be possible with effort to make it build, but it seems rather pointless since glibc includes a libiconv implementation. ## Things done - Built on platform(s) - [x] x86_64-linux - [ ] aarch64-linux - [x] x86_64-darwin - [x] aarch64-darwin - For non-Linux: Is sandboxing enabled in `nix.conf`?
