This doesn't change uniq. Why not?
- In NixOS it seems that uniq is only used with
simple types that are fully checked by t.check.
- It exists for much longer and is used more widely.
- I believe we should deprecate it, because unique was
already better.
- unique can be a proving ground.
Type: either ints.positive (enum ["auto"])
Before: positive integer, meaning >0 or value "auto" (singular enum)
After: positive integer, meaning >0, or value "auto" (singular enum)
This type is necessary to have correct merging behavior for
`allowUnfreePredicate` and `allowInsecurePredicate`

This reverts commit c59c6b1c57.
This was a bit too ambitious, because no warnings were previously
triggered when `string` was nested e.g. `attrsOf string`, `nullOr
string`, etc.
Support for nested type deprecation warnings was introduced in
4b54aedee5, but had to be reverted in
a36e6760e9 because it caused infinite
recursion for some users, and I couldn't remember that it was reverted.
The type has given a warning on use since [4 years ago](03392cd336b128a1639c648baf0f6c1a1271e0d2), I think it's safe to move the deprecation to the next stage: An error instead of a warning.
The motivation is to have a single identifier for that. Useful for the
next commit where I'll try to escape option-parts correctly (options can
be any kind of strings, but unless these are Nix identifiers, they must
be quoted).
Since `<function body>` (or `<name>`/`*`) are special identifiers in
error messages and the manual, we need a unique way to mark an option
part as function call because these are not to be quoted.
More nixpkgs code such as `boot.initrd.systemd.emergencyAccess` defines
options that takes hashed passwords, so move the type definition from
modules/ into lib/.
The type definition itself stays unchanged.
Currently the only way to set the description for a submodule type is to
use `freeformType`. This is not ideal as it requires setting a
freeform type, and evaluates the submodule config unnecessarily.
Instead, add a `description` argument to `submoduleWith`.
Probably being the most prominent document demonstrating the problem,
configuration.nix(5) describes various types in plural, e.g.
- ` Type: list of strings`
- ` Type: list of systemd options`
However, there are other cases where appending "s" to the inner type
effectively changes the type, e.g.
- ```
Type: list of string matching the pattern
[a-zA-Z0-9@%:_.\-]+[.](service|socket|device|mount|automount|swap|target|path|timer|scope|slice)s
```
This should've read "list of string[s]..." but instead changes the
regular expression.
Simply drop the best-effort plural in favour of correctness and
simplicity rather than adding more grammar related logic/trying to fix
this.
types.optionSet has been deprecated for almost 10 years now
(0e333688ce)! A removal
was already attempted in 2019
(27982b408e), but it was promptly
reinstantiated since some third-party uses were discovered
(f531ce75e4178c6867cc1d0f7fec96b2d5c3f1cb).
It's finally time to remove it for good :)
