Robert Hensing 1107ea363f libmain: Clarify the lack of initLibExpr()
Quote

    Why not initLibExpr()? initGC() is essentially that, but
    detectStackOverflow is not an instance of the init function concept, as
    it may have to be invoked more than once per process.

Furthermore, renaming initGC to initLibExpr is more trouble than it's
worth at this time.

Robert Hensing 52d6ce6515 Move macOS TMPDIR hack from initNix to initLibStore
This code is bad. We shouldn't unset variables in programs whose
children may need them. Fixing one issue at a time, so postponing.
See https://github.com/NixOS/nix/issues/7731

Part of an effort to make it easier to initialize the right things,
by moving code into the appropriate libraries.

Robert Hensing e706ffa007 Move preloadNSS() from initNix to initLibStore
It is required for the sandbox, which is a libstore responsibility;
not just libmain.

Part of an effort to make it easier to initialize the right things,
by moving code into the appropriate libraries.

Robert Hensing 9693076715 Move initLibStore() immediately after initLibUtil()
Part of an effort to make it easier to initialize the right things,
by moving code into the appropriate libraries.

The goal of this reordering is to make initLibStore self-sufficient
in a following commit.

Robert Hensing a692c43729 Move loadConfFile() to initLibStore
Part of an effort to make it easier to initialize the right things,
by moving code into the appropriate libraries.

Using libstore without loading the config file is risky, as sqlite
may then be misconfigured. See https://github.com/cachix/cachix/issues/475

Finish converting existing comments for internal API docs (#8146)
* Finish converting existing comments for internal API docs

99% of this was just reformatting existing comments. Only two exceptions:

- Expanded upon `BuildResult::status` compat note

- Split up file-level `symbol-table.hh` doc comments to get
  per-definition docs

Also fixed a few whitespace goofs, turning leading tabs to spaces and
removing trailing spaces.

Picking up from #8133

* Fix two things from comments

* Use triple-backtick not indent for `dumpPath`

* Convert GNU-style `\`..'` quotes to markdown style in API docs

This will render correctly.

John Ericson b200784cec Include the name in the JSON for derivations
This is non-breaking change in the to-JSON direction. This *is* a

is brand new in this PR.

`nix show-derivation --help` currently has the sole public documentation
of this format, it is updated accordingly.

Théophane Hufschmitt 214f1d6791 Rename and protect BufferedSink::write
The `write` name is ambiguous and could lead to some funny bugs like
https://github.com/NixOS/nix/pull/8173#issuecomment-1500009480. So
rename it to the more explicit `writeUnbuffered`.
Besides, this method shouldn't be (and isn't) used outside of the class
implementation, so mark it `protected`.

This makes it more symetrical to `BufferedSource` which uses a
`protected readUnbuffered` method.

matthewcroughan 9207f94582 Add Store::isTrustedClient()
This function returns true or false depending on whether the Nix client
is trusted or not. Mostly relevant when speaking to a remote store with
a daemon.

We include this information in `nix ping store` and `nix doctor`

John Ericson bc192a95ef Describe active experimental features in the contributing guide
They are put in the manual separate pages under the new overarching
description of experimental features.

The settings page just lists the valid experimental feature names (so
people know what a valid setting entry looks like), with links to those
pages. It doesn't attempt to describe each experimental feature as that
is too much information for the configuration settings section.

Eelco Dolstra 94812cca98 Backport SourcePath from the lazy-trees branch
This introduces the SourcePath type from lazy-trees as an abstraction
for accessing files from inputs that may not be materialized in the
real filesystem (e.g. Git repositories). Currently, however, it's just
a wrapper around CanonPath, so it shouldn't change any behaviour. (On
lazy-trees, SourcePath is a <InputAccessor, CanonPath> tuple.)

It should be syntethised in terms of `operator==`, but the GCC version

John Ericson 53d0836347 Assemble experimental feature docs outside of Nix itself
Instead of constructing a markdown list in C++ (which involved all sorts
of nasty string literals), export some JSON and assemble it with the
manual build system.

Besides following the precedent set with other dumped data, this is a
better separate of content and presentation; if we decide for example we
want to display this information in a different way, or in a different
section of the manual, it will become much easier to do so.
