nix::fetchers::CacheImpl uses $XDG_CACHE_HOME, or its default based on
$HOME, to store its SQLite database. If the current process can't write
to that directory for whatever reason, though, any eval-time fetching
would fail just initializing the cache.
With this change, IO errors initializing the fetcher cache are logged
but ignored, and nix::fetchers::CacheImpl falls back to an in-memory¹
database instead.
Notably, this will fix any uses eval fetching while Lix itself is being
run in a derivation builder (such as during tests), as the derivation
builder does not set $XDG_CACHE_HOME, and sets $HOME to the non-existent
directory /homeless-shelter.
Before:
$ env -u XDG_CACHE_HOME HOME=/homeless-shelter nix -Lv eval --impure -E 'fetchTarball "https://git.lix.systems/lix-project/lix/archive/main.tar.gz"'
error:

This turns errors like:
error: flake output attribute 'hydraJobs' is not a derivation or path
into errors like:
error: expected flake output attribute 'hydraJobs' to be a derivation or
path but found a set: { binaryTarball = «thunk»; build = «thunk»; etc> }
This change affects all InstallableFlake commands.

Move the identical static `chmod_` functions in libstore to
libutil. the function is called `chmodPath` instead of `chmod`
as otherwise it will shadow the standard library chmod in the nix
namespace, which is somewhat confusing.

2bbe3efd1¹ added the -Wdeprecated-copy warning, and fixed the instances
of it which GCC warned about, in HintFmt and ref<T>. However, when
building with Clang, there is an additional deprecated-copy warning in
BaseError. This commit explicitly defaults the copy assignment operator
for BaseError and silences this warning.

having the serializer write into `*conn` is not legal because we are
in a sinkToSource that will be drained by the remote we're connected
to. writing into `*conn` directly can break the framing protocol. it
is unlikely this code was ever run: to protocol it caters to is from
2016(!) and thoroughly untested in-tree, and since it's been present
since nix 2.17 and the 1.18 protocol broken here is nix 2.0 we might
safely assume that daemons older than nix 2.1 are no longer used now
see also #325 (though that wants <2.3 gone, this is sadly only <2.1)

On several occasions I've found myself confused when trying to delete
a store path, because I am told it's still alive, but
nix-store --query --roots doesn't show anything. Let's save future
users this confusion by mentioning that a path might be alive due to
having referrers, not just roots.

These commands outputs data that may not end with a newline. This
causes problems when the progress bar redraws, as that completely
wipes the last line of output. As nix key generate-secret outputs
a single line of text with no output, it shows up entirely blank,
making it look like nothing happened.

to a vendored flake-registry.json file in the install path.
Vendored copy of the flake-registry is from github:NixOS/flake-registry

Both of these still needs their own actual documentation, but they are
at least now mentioned that they exist and what they're enabled by.

This is nonsensical since selecting outputs can only be done for a
buildable derivation, not for a realised store path. The build worker
side of things ends up crashing with an assertion when trying to handle
such malformed paths.

This builtin was always a problem and nixpkgs uses it in exactly one
place, to give up if the Nix version is absurdly old. It has no other
use cases, and doesn't work in a multi-implementation world anyway.

There are a few places in nixpkgs lib where `**Foo**:` is used as a heading instead of the usual markdown `# Foo` ones. I think this is intentional with how it gets rendered in the manual, e.g. [`lib.lists.sortOn`][1].
[1]: https://nixos.org/manual/nixpkgs/stable/#function-library-lib.lists.sortOn
`nix-doc` prints this as
```
*Laws**:
```nix
sortOn f == sort (p: q: f p < f q)
```
```
chomping off the first asterisk as part of `cleanup_single_line` that's meant to deal with `/** \n * \n * \n */` style doc comments. This also means the usage in lix ends up funny-looking with a trailing asterisk as if there's a footnote to pay attention to (which is how I first noticed it, heh)
The fix:
When cleaning up a single line and removing a prefix comment character,
ensure it's followed by whitespace (or the last character of the line).

Surely if you have unreleased changes you want them on a page right?
`officialRelease` means "this is a *release version*", which is a
reasonable case to not want it, but we are not that here.
I understand wanting to be able to turn it off for deps reasons or
something, but other than that, uhh, seems better to just turn it on
always; it is basically free compute-wise to the point we run it on
pre-commit.
Part two of fixing lix#297.

This allows us to have links to peoples' GitHub and Forgejo profiles.
I used YAML because I don't want to introduce a dependency on having a
working Nix evaluator to be able to build release notes, and we already
have a YAML parser in this script.

This does not add missing release notes, and it doesn't do anything
about the profiles feature we would really like to have so we can have
consistent credit.

This was a combination of two problems: the python didn't throw an error
because apparently glob on a nonexistent directory doesn't crash, and
secondarily, bash ignores bad exit codes without `set -e` if they are
not in the final/only command.

Use the correct directory for the rl-next build, so that the release notes
actually get built and the page doesn't end up empty. I don't know why the
exception didn't cause a build failure before.

Basically I'd expect the same behavior as with `nix-build`, i.e.
with `--keep-going` the hash-mismatch error of each failing
fixed-output derivation is shown.
The approach is derived from `Store::buildPaths` (`entry-point.cc`):
instead of throwing the first build-result, check if there are any build
errors and if so, display all of them and throw after that.
Unfortunately, the BuildResult struct doesn't have an `ErrorInfo`
(there's a FIXME for that at least), so I have to construct my own here.
This is a rather cheap bugfix and I decided against touching too many
parts of libstore for that (also I don't know if that's in line with the
ongoing refactoring work).
