Also, output the paths in topologically sorted order like we used to.
This is important if the remote side *does* execute
nix-store/nix-daemon successfully, but stdout is polluted
(e.g. because the remote user's bashrc script prints something to
stdout). In that case we have to shutdown the write side to force the
remote nix process to exit.
Instead of
error: serialised integer 7161674624452356180 is too large for type 'j'
we now get
error: 'nix-store --serve' protocol mismatch from 'sshtest@localhost', got 'This account is currently not available.'

It's now disabled by default for the following:
* 'nix search' (this was already implied by read-only mode)
* 'nix flake show'
* 'nix flake check', but only on the hydraJobs output
Without this, flakes within the same tree and same lock data will have
the same fingerprint and the eval cache for one flake will be
incorrectly used for another.
Alternative to #4639. You can still read flake.lock, but at least in
reproducible workflows like NixOS configurations where you require a
non-dirty tree, evaluation will fail because there is no rev.
With --no-write-lock-file, it's possible that flake.lock is out of
sync with the actual inputs used by the evaluation. So doing fromJSON
(readFile ./flake.lock) will give wrong results.
Fixes#4639.
Before this commit, the dns lookup in preloadNSS would still go through
nscd. This did not have the effect of loading the nss_dns.so as expected
(nss_dns.so being out of reach from within the sandbox).
Should LOCALDOMAIN environment variable be defined, nss will completely
avoid nscd and will do its dns resolution on its own.
By temporarly setting LOCALDOMAIN variable before calling in NSS, we can
force NSS to load the shared libraries as expected.

In dry run mode, new derivations can't be create, so running the command on anything that has not been evaluated before results in an error message of the form `don't know how to build these paths (may be caused by read-only store access)`.
For comparison, the classical `nix-build --dry-run` doesn't use read-only mode.
Closes#1795
(cherry picked from commit 54525682df707742e58311c32e9c9cb18de1e31f)
If the store path contains a flake, this means that a command like
"nix path-info /path" will show info about /path, not about the
default output of the flake in /path. If you want the latter, you can
explicitly ask for it by doing "nix path-info path:/path".
Fixes#4568.
Store paths are only allowed to contain a limited subset of the
alphabet, which doesn’t include `!`. So don’t create lockfiles that
contain this `!` character as that would otherwise confuse (and break)
the gc.
Fix#5176
When doing e.g.
nix-build -A package --keep-failed --option \
builders \
'ssh://mfhydra?remote-store=/home/bosch/store x86_64-linux - 10 4 big-parallel'
this doesn't work properly because this build-setting is ignored.
I changed this behavior by passing the `settings.keepFailed` through the
serve-protocol to remote machines to make sure that I can introspect the
build-directory (which is particularly helpful when I have to look at a
`config.log` from a failed build for instance).
This fixes a use-after-free bug:
1. s = new EvalState();
2. callFlake()
3. static vCallFlake now references s
4. delete s;
5. s2 = new EvalState();
6. callFlake()
7. static vCallFlake still references s
8. crash
Nix 2.3 did not have a problem with recreating EvalState.
This fixes a class of crashes and introduces ptr<T> to make the
code robust against this failure mode going forward.
Thanks regnat for the idea of a ref<T> without overhead!

“packages” was probably meant to be “packages.${system}.” but that
is already listed in `getDefaultFlakeAttrPathPrefixes` in `installables`,
which is probably why no one noticed it was broken.
It currently fails with the following error:
error: flake 'git+file://…' does not provide attribute 'devShells.x86_64-linuxhaskell', 'packages.x86_64-linux.haskell', 'legacyPackages.x86_64-linux.haskell' or 'haskell'
For git+file and path flakes, chdir to flake directory so that phases
that expect to be in the flake directory can run
