All OS and IO operations should be moved out, leaving only some misc
portable pure functions.
This is useful to avoid copious CPP when doing things like Windows and
Emscripten ports.
Newly exposed functions to break cycles:
- `restoreSignals`
- `updateWindowSize`
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`

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.)
to each Store implementation. The generic regStore implementation will
only be for the ambiguous shorthands, like "" and "auto".
This also could get us close to simplifying the daemon command.
When running nix doctor on a healthy system, it just prints the store URI and
nothing else. This makes it unclear whether the system is in a good state and
what check(s) it actually ran, since some of the checks are optional depending
on the store type.
This commit updates nix doctor to print an colored log message for every check
that it does, and explicitly state whether that check was a PASS or FAIL to make
it clear to the user whether the system passed its checkup with the doctor.
Fixes#3084
Calculating roots seems significantly slower on darwin compared to
linux. Checking for /profile/ links could show some false positives but
should still catch most issues.
It's pretty easy to unintentionally install a second version of nix
into the user profile when using a daemon install. In this case it
looks like nix was upgraded while the nix-daemon is probably still
unning an older version.
A protocol mismatch can sometimes cause problems when using specific
features with an older daemon. For example:
Nix 2.0 changed the way files are compied to the store. The daemon is
backwards compatible and can still handle older clients, however a 1.11
nix-daemon isn't forwards compatible.
