We’ve never deprecated a platform in widespread use before, and it
seems prudent to warn users about the upcoming end of support so they
can plan appropriately.
I tried to make this relatively unobtrusive by taking advantage of
the import cache and offering a way to turn it off, but I anticipate
there might still be issues with e.g. `nix shell nixpkgs#…` and
spammy warnings from multiple instantiations of Nixpkgs. I’m
not sure there’s much we can do about that unless we take a
different strategy entirely; `nix shell --impure nixpkgs#…` with a
`~/.config/nixpkgs/config.nix` is about the best UX we can hope to
offer with the restrictions of flakes.
Inspired by https://github.com/NixOS/nixpkgs/issues/197325 this adds a
new option nixpkgs.allowUnfreePackages, which merges additively and can
thus be defined in multiple modules close to where the unfree package is
installed.
I would have liked ot name this option
nixpkgs.config.allowUnfreePackages, to define it closer to where the
allowUnfree and allowUnfreePredicate are defined, but I didn't see how
this could be achived. I would welcome some guidance on how to do this.
Allows having alternate hashed mirrors as fallbacks. Useful in case the
default hashed mirror is not accessible or doesn't have everything
needed.

This allows on-the-fly rewriting of URLs before they are passed from
fetchurl (or fetchurlBoot) to curl.
The intended use is to allow inserting company-internal mirrors, or
working around company firewalls and similar network restrictions,
without having to extensively patch across all of nixpkgs. Instead,
users can pass a function in their nixpkgs that performs the necessary
URL rewrites.

This patch adds `lib.repoRevToName` function that generalizes away most of the
code used for derivation name generation by `fetch*` functions (`fetchzip`,
`fetchFromGitHub`, etc, except those which are delayed until latter commits
for mass-rebuild reasons).
It's first argument controls how the resulting name will look (see below).
Since `lib` has no equivalent of Nixpkgs' `config`, this patch adds
`config.fetchedSourceNameDefault` option to Nixpkgs and then re-exposes
`lib.repoRevToName config.fetchedSourceNameDefault` expression as
`pkgs.repoRevToNameMaybe` which is then used in `fetch*` derivations.
The result is that different values of `config.fetchedSourceNameDefault` now
control how the `src` derivations produced by `fetch*` functions are to be
named, e.g.:
- `fetchedSourceNameDefault = "source"` (the default):
```
$ nix-instantiate -A fuse.src
/nix/store/<hash>-source.drv
```
- `fetchedSourceNameDefault = "versioned"`:
```
$ nix-instantiate -A fuse.src
/nix/store/<hash>-libfuse-2.9.9-source.drv
```
- `fetchedSourceNameDefault = "full"`:
```
$ nix-instantiate -A fuse.src
/nix/store/<hash>-libfuse-2.9.9-github-source.drv
```
See the documentation of `config.fetchedSourceNameDefault` for more info.

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.
This caused too many downstream projects to break, so we are reverting
this change for now, until further transition fixes are in place.
