This caused nlohmann/json.hpp to leak into a lot of compilation units,
which is slow (when not using precompiled headers).
Cuts build time from 46m24s to 42m5s (real time with -j24: 2m42s to
2m24s).
These versions are more than 3 years old and were very early in the
existence of CA derivations support (which was and is experimental),
so they're unlikely to still exist in the real world. So let's get rid
of support for them.
The previous documentation was inaccurate, stating that it would not update existing inputs. However these inputs will be updated if they are outdated (for example the version of an existing input has been changed). The new text properly reflects this behaviour.
A test added recently checks that when trying to deserialize a NAR with
two files that Unicode-normalize to the same result either succeeds on
Linux, or fails with an "already exists" error on Darwin. However,
failing with an "already exists" error can in fact also happen on Linux,
when using ZFS with the proper utf8 and Unicode normalization options
set.
This commit fixes the issue by not assuming the behavior from the
current system, but just by blindly checking that either one of the two
aforementioned possibilities happen, whether on Darwin or on Linux.
Additionally, we check that the Unicode normalization behaviour of
nix-store is the same as the host file system.
This leads to confusion about what the command does.

- Move the description up
- Remove details about the individual formatters

When working on speeding up the CI,
I triggered a race condition in the creation of the tarball cache.
This code now instead will ensure that half-initialized repositories
are no longer visible to any other nix process.
This is the error message that I got before:
error: opening Git repository '"/Users/runner/.cache/nix/tarball-cache"': could not find repository at '/Users/runner/.cache/nix/tarball-cache'
* docs: specify that flake.lock files are JSON
Recently, I decided that I was going to write some code that would parse
flake.lock files. I went to the Nix Reference Manual in order to look up
information on the format of flake.lock files, and I realized that a key
detail was missing from the Nix Reference Manual: it never says that
flake.lock files are JSON files. This commit fixes that issue.
This commit makes sure to specify that flake.lock files are encoded in
UTF-8. Confusingly, there’s multiple different JSON standards. Neither
ECMA-404, 2nd Edition [1] nor ISO/IEC 21778:2017 [2] mention UTF-8. RFC
8259 requires UTF-8, but only sometimes [3]. I chose to explicitly
specify that flake.lock files are UTF-8 in order to avoid any possible
ambiguities from the JSON standards.
[1]: <https://ecma-international.org/publications-and-standards/standards/ecma-404>
[2]: <https://www.iso.org/standard/71616.html>
[3]: <https://www.rfc-editor.org/rfc/rfc8259.html#section-8.1>
Most of the time people run single tests for debugging reason,
so it's a sane default to have them see all the console output.
This commit still retains the section about running tests directly with
meson, because in some debugging cases it's just nice to have less
abstractions i.e. when using strace.
Since #8766, invalid base64 is rendered in errors, but we don't actually
want to show this in the case of an invalid private keys.
