regnat 92656da0b9 Fix the gc with indirect self-references via the realisations
If the derivation `foo` depends on `bar`, and they both have the same
output path (because they are CA derivations), then this output path
will depend both on the realisation of `foo` and of `bar`, which
themselves depend on each other.
This confuses SQLite which isn’t able to automatically solve this
diamond dependency scheme.

Help it by adding a trigger to delete all the references between the
relevant realisations.

Fix #5320

Sergei Trofimovich 6ada496311 nix: add (failing) selfreference test for multiple realizations
The test illustrates failure in issue #5320. Here derivation and
it's built input have identical CA sotre path. As a result we generate
extraneout reference to build input:

    $ make installcheck
    ...
    ran test tests/selfref-gc.sh... [PASS]
    ran test tests/ca/selfref-gc.sh... [FAIL]
    ...

John Ericson f63b0f4540 Actually, solve this in a lighter-weight way
The templating is very superficial
2022-04-20 17:37:59 +00:00
John Ericson 05ec0beb40 Move templated functions to sqlite-impl.hh
This ensures that use-sites properly trigger new monomorphisations on
one hand, and on the other hand keeps the main `sqlite.hh` clean and
interface-only. I think that is good practice in general, but in this
situation in particular we do indeed have `sqlite.hh` users that don't
need the `throw_` function.

Yorick ebf2fd76b1
Add custom to_json and from_json functions for ExperimentalFeature
nix show-config --json was serializing experimental features as ints.
nlohmann::json will automatically use these definitions to serialize
and deserialize ExperimentalFeatures.

Strictly, we don't use the from_json instance yet, it's provided for
completeness and hopefully future use.

nix repl: make symlinks with the :bl command
Requested by ppepino on the Matrix:
https://matrix.to/#/!KqkRjyTEzAGRiZFBYT:nixos.org/$Tb32BS3rVE2BSULAX4sPm0h6CDewX2hClOTGzTC7gwM?via=nixos.org&via=matrix.org&via=nixos.dev

This adds a new command, :bl, which works like :b but also creates
a GC root symlink to the various derivation outputs.

ckie@cookiemonster ~/git/nix -> ./outputs/out/bin/nix repl
Welcome to Nix 2.6.0. Type :? for help.

nix-repl> :l <nixpkgs>
Added 16118 variables.

nix-repl> :b runCommand "hello" {} "echo hi > $out"

This derivation produced the following outputs:
  ./repl-result-out -> /nix/store/kidqq2acdpi05c4a9mlbg2baikmzik44-hello
[1 built, 0.0 MiB DL]
ckie@cookiemonster ~/git/nix -> cat ./repl-result-out

Eelco Dolstra d89840b103 Make InstallableFlake::toValue() and toDerivation() behave consistently
In particular, this means that 'nix eval` (which uses toValue()) no
longer auto-calls functions or functors (because
AttrCursor::findAlongAttrPath() doesn't).

Fixes #6152.

Also use ref<> in a few places, and don't return attrpaths from
getCursor() because cursors already have a getAttrPath() method.

Martin Schwaighofer 4f29cf1a1d installer: ask for confirmation on multi-user install without systemd
On Linux a user can go through all the way through the multi-user install
and find out at the end that they now have to manually configure their
init system to launch the nix daemon.

I suspect that for a significant number of users this is not
what they wanted. They might prefer a single-user install.
Now they have to manually uninstall nix before they can
go through the single-user install.

This introduces a confirmation dialog before the install
in that specific situation to make sure that they want to proceed.

See also: https://github.com/NixOS/nix/issues/4999#issuecomment-1064188080
This closes #4999 but rejecting it and closing that issue anyways
would also be valid.
