2021-09-30`std::visit` by referenceJohn Ericson
I had started the trend of doing `std::visit` by value (because a type error once mislead me into thinking that was the only form that existed). While the optomizer in principle should be able to deal with extra coppying or extra indirection once the lambdas inlined, sticking with by reference is the conventional default. I hope this might even improve performance.
2021-09-02Don't use read-only mode for nix build --dry-runGeorges Dubus
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)
2021-07-22Use eval-store in more placesEelco Dolstra
In particular, this now works: $ nix path-info --eval-store auto --store https://cache.nixos.org nixpkgs#hello Previously this would fail as it would try to upload the hello .drv to cache.nixos.org. Now the .drv is instantiated in the local store, and then we check for the existence of the outputs in cache.nixos.org.

This allows us to namespace its constructors under it.

2020-10-09Split out `local-fs-store.hh`John Ericson
This matches the already-existing `local-fs-store.cc`.
2020-10-06Remove static variable name clashesEelco Dolstra
This was useful for an experiment with building Nix as a single compilation unit. It's not very useful otherwise but also doesn't hurt...

2020-07-31nix/build: add `--rebuild` optionMaximilian Bosch
Occasionally, `nix-build --check` is fairly helpful and I'd like to be able to use this feature for flakes that need to be built with `nix build` as well.
2020-07-23Make `Buildable` a `std::variant`John Ericson
I think this better captures the intent of what's going on: we either have an opaque store path, or a drv path with some outputs. Having this structure will also help us support CA derivations: we'll have to allow the outpath paths to be optional, so the structure we gain now makes up for the structure we loose then.

This also adds a '--profile' option to 'nix build' (replacing 'nix-env --set').

2019-07-12nix build: Add '--profile' flagEelco Dolstra
This replaces 'nix-env --set'. For example: $ nix build --profile /nix/var/nix/profiles/system \ ~/Misc/eelco-configurations:nixosConfigurations.vyr.config.system.build.toplevel updates the NixOS system profile from a flake. This could have been a separate command (e.g. 'nix set-profile') but 1) '--profile' is pretty similar to '--out-link'; and 2) '--profile' could be useful for other command (like 'nix dev-shell').

2019-04-19Use "." as the default installableEelco Dolstra
This makes e.g. "nix build" do something more or less reasonable (namely, build the default package of the flake in the current directory).
2019-04-16Update lock files from InstallableFlake::toValue()Eelco Dolstra
This ensures that the lock file is updated *before* evaluating it, and that it gets updated for any nix command, not just 'nix build'. Also, while computing the lock file, allow arbitrary registry lookups, not just at top-level. Also, improve some error messages slightly.
