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.)

Théophane Hufschmitt faefaac875 Explicitely define LockFile::operator!=
It should be syntethised in terms of `operator==`, but the GCC version
used on aarch64-linux doesn't implement that (see
https://hydra.nixos.org/build/214848896=. So explicitely define it.

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.

Robert Hensing bf2c5c3958 nix-store.cc: Refactor, remove qDefault 2023-04-03 18:45:20 +02:00
Robert Hensing fba7be80eb Enable -Werror=switch-enum
switch statements must now match all enum values or disable the
warning.

Explicit is good. This has helped us find two bugs, after solving
another one by debugging.

From now on, adding to an enum will raise errors where they are
not explicitly handled, which is good for productivity, and helps
us decide the correct behavior in all usages.

Notably still excluded from this though are the cases where the
warning is disabled by local pragmas.

fromTOML.cc did not build despite a top-level pragma, so I've had
to resort to a makefile solution for that.

John Ericson 4a0b893d5e Stuctured command stability
Prior to this, there was an ad-hoc whitelist in `main.cc`. Now, every
command states its stability.

In a future PR, we will adjust the manual to take advantage of this new
information in the JSON.
(It will be easier to do that once we have some experimental feature
docs to link too; see #5930 and #7798.)

John Ericson 9383520b75 Move querySubstitutablePathInfos from LocalStore to Store
The code is not local-store-specific, so we should share it with all
stores. More uniform behavior is better, and a less store-specific
functionality is more maintainable.

This fixes a FIXME added in f73d911628 by @edolstra himself.

John Ericson ca3937fb82 Mention internal API docs in PR template
I think we want to ensure that all new items in headers are documented,
and the documentation on modified items is kept up to date.

It will take a while to document the backlog of undocumented things, but
we can at least ensure that new items don't extend that backlog.
