piegamesandCommentator2.0 56dee9186f libexpr: Warn on incorrect string escapes
In Nixpkgs, there are several strings like "\d\.\d" which attempt to be
a regex but are just literally "d.d". The escaping rules are silly and
we should warn our users about that.

piegamesandCommentator2.0 f1fbd1d095 libexpr: Warn on incorrect string usage
The indentation stripping semantics of strings are fairly bad and have a
few gotchas where they behave unintuitively. But the good news is, that
these cases are easy to catch and can be avoided.
This commit adds a warning in the parser when such strings are detected.

Unfortunately Nixpkgs uses this kind of a lot, so we won't be able to
actually enable this warning for a while to come.

eldritch horrors 56988d8605 libstore: use vfork for linux sandbox launch wrappers
this halves sandbox launch overhead, reducing the build time for 3000
trivial runCommand derivations on our machine from 80 seconds to 44s.
as a nice side effect we also get better error message propagation in
some cases, most notably setgroups failing when run in lix sandboxes.

Raito BezariusandTom Hubrecht c493fb668e nix/daemon: consider supplementary groups during authentication
Two things happens here:

- we consider supplementary groups that are known for authentication,
fixes #968.

- we check supplementary groups if they are our build users group and
throw an error if they are (new behavior).

Nonetheless, we did not remove the ability for `matchUser` to recurse
and check for groups that the user may have but the connection might not
have communicated as part of their groups, i.e. if a process reduces its
list of groups via a call to setgroups, it will still be authorized.
This will come in another commit.

The authorization NixOS test has been extended with a store ping test
running in systemd with DynamicUser=true *AND* a supplementary group in
allowed-users.

Raito BezariusandNiko Klanecek 728d2bfee7 contrib/plugins: add mTLS binary cache store plugin
Adds an example plugin implementing an mTLS-enabled binary cache store
(https+mtls:// scheme) using client certificates for authentication.

Darwin fix: don't link liblix* into plugins (host resolves symbols at
runtime via dynamic_lookup). Explicitly link curl so it binds to
Nix-store libcurl, not /usr/lib/libcurl. This prevents the plugin's
curl_easy_setopt calls from operating on the wrong libcurl instance.

Test portability: BSD sed -i wrapper, OpenSSL -sha256 for cert signing,
redirect test server output to log file.

Tom Hubrecht 7d764670c8 nix/path-info: Don't print missing paths as no fetch can be done
Fixes #323

Let's now all go an a little rant about spaghetti code...

The result of this code is that the missing paths are not printed
anymore. The basic issue was that the parent class of this command is
StorePathsCommand, which inherits from BuiltPathsCommand, and their
purpose is to work on path that are clearly in the store, building them
if needed (and ofc telling the user about what's missing), the sequance
of calls is:

- BuiltPathsCommand::run(ref<Store> store, Installables && installables)
- Installable::toBuiltPaths( *getEvaluator()->begin(aio()),
getEvalStore(), store, realiseMode, operateOn, installables);
  where operateOn is Output by default, realiseMode is Derivation, so
the only thing that can be built are the derivations for the required
installables
- Installable::build(state, evalStore, store, mode, installables)
- Installable::build2(state, evalStore, store, mode, installables,
bMode)

And that final call has the following:

```
    switch (mode) {

    case Realise::Nothing:
    case Realise::Derivation:
        state.aio.blockOn(printMissing(store, pathsToBuild, lvlError));
```

So there were two options, hack a new spaghetti in the existing
spaghetti code, or condense all those calls that are actually useless in
our case because they mostly transform a list of installables into a map
from installables to their BuiltPath which are then iterated to retrieve
the final outputs, whereas it is possible to directly get the required
paths in a much more efficient manner and without printing unrequired
stuff through a multitude of intertwined function calls by simply
replacing one method that was previously inherited from the grandparent
class

Raito Bezarius e9cccd47e2 libstore/build: report better error messages for --check
When --check is ran with no output, this is seen as having *SOME*
invalid outputs, actually, ALL of them are invalid here.

Instead of reporting a confusing error, let's consider ALL of outputs
being invalid to be no output at all available and advise the user to
rerun the build without --check.

If there's *some* (>0) invalid outputs, let's print them exactly to give
a chance to the user to remediate this.

Fixes #485.

eldritch horrors 521b42866d nix/daemon: socket-activate single connections
the cgroups experimental feature does not work properly without this
because we do not stop subdaemons when the main daemon is shut down.
systemd needs the assigned cgroups to be empty to restart the daemon
and thus cannot cleanly restart the daemon if any connections exist.
starting a fresh unit for each connection creates a new cgroup every
time instead of sharing any delegations and thus solves the problem.

Raito Bezarius 1e98c01912 libutil/users: support service cache directories
Nix daemon runs in a service context, usually with systemd.

If the Nix daemon unit adds `[Service] CacheDirectory=nix-daemon`, it should
successfully use `/var/cache/nix-daemon` automatically.

Instead, it uses `/root/.cache` right now, which is really bad.

By default, we add `[Service] CacheDirectory=nix` now which means that
caches are moved into `/var/cache/nix`.

Fixes #634.

Alois Wohlschlager 00dfcc81b4 doc: fix substitution with mdbook 0.4
Recently, in 54df89f601, support for mdbook 0.5
was introduced, including some logic to handle the `sections` -> `items`
rename. However, compatibility with 0.4's `sections` was only kept on the read
path, while writing 0.5's `items` unconditionally, which ends up in the bit
bucket on 0.4, effectively disabling substitution fully and leaving the include
directives in the final documentation. Restore writing into the `sections` when
they were there so that substitution works again.

Emilia BoppandQyriad 0ade82d23a libexpr: add builtins.warn
Added builtins.warn` which takes two arguments: a message that is
displayed as a warning during evaluation which must be a string and a
value that is returned from the expression.

The next commits add new settings to control the behavior of the new
builtin: `debugger-on-warn` allows the user to start the debugger and
`abort-on-warn` aborts evaluation with an error.

Unlike upstream, I chose not to mark evaluation warnings from
`builtins.warn` as distinct from other warnings because that breaks the
commonly expected logging format `level: message`.
