The release notes document the change in behavior, I don't include it here so there is no risk to it getting out of sync. > Motivation >> Plumbing CLI should be simple Store derivation installations are intended as "plumbing": very simple utilities for advanced users and scripts, and not what regular users interact with. (Similarly, regular Git users will use branch and tag names not explicit hashes for most things.) The plumbing CLI should prize simplicity over convenience; that is its raison d'etre. If the user provides a path, we should treat it the same way not caring what sort of path it is. >> Scripting This is especially important for the scripting use-case. when arbitrary paths are sent to e.g. `nix copy` and the script author wants consistent behavior regardless of what those store paths are. Otherwise the script author needs to be careful to filter out `.drv` ones, and then run `nix copy` again with those paths and `--derivation`. That is not good! >> Surprisingly low impact Only two lines in the tests need changing, showing that the impact of this is pretty light. Many command, like `nix log` will continue to work with just the derivation passed as before. This because we used to: - Special case the drv path and replace it with it's outputs (what this gets rid of). - Turn those output path *back* into the original drv path. Now we just skip that entire round trip! > Context Issue #7261 lays out a broader vision for getting rid of `--derivation`, and has this as one of its dependencies. But we can do this with or without that. `Installable::toDerivations` is changed to handle the case of a `DerivedPath::Opaque` ending in `.drv`, which is new: it simply doesn't need to do any extra work in that case. On this basis, commands like `nix {show-derivation,log} /nix/store/...-foo.drv` still work as before, as described above. When testing older daemons, the post-build-hook will be run against the old CLI, so we need the old version of the post-build-hook to support that use-case. Co-authored-by: Travis A.
