It has been dead code since 9747ea84b43c75f719d719673b9d0a7cb50d34e5.

Improve error on conflict for nix profile install
|
|
|
|
|
|
For brand new installations, neither NIX_LINK_NEW
(`$XDG_STATE_HOME/nix/profile` or `~/.local/state/nix/profile`), nor
NIX_LINK (`~/.nix-profile`) will exist.
This restores functionality to nix-env, which is relied upon by GitHub
Actions such as https://github.com/cachix/cachix-action and the Nixpkgs
EditorConfig (and other) CI.

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.

nix-profile{,-daemon}.sh.in: Allow XDG_STATE_HOME to be unset
|
|
One of our CI machines installs Nix via the official script and then
sources the nix-profile.sh script to setup the environment. However, it
doesn't have XDG_STATE_HOME set, which causes sourcing the script to
fail.
|
|
cli-guideline: Add JSON guideline
|
|
Turns out that the settings themselves have a bad data model anyway, so we cut that. They do still occur in the first example, but not in focus.

Thanks Valentin!

Whenever a file conflict happens during "nix profile install" an error
is shown that was previously thrown inside builtins.buildEnv.
We catch BuildProfileConflictError here so that we can provide the user
with more useful instructions on what to do next.
Most notably, we give the user concrete commands to use with all
parameters already filled in. This avoids the need for the user to look
up these commands in manual pages.

At the moment an Error is thrown that only holds an error message
regarding `nix-env` and `nix profile`. These tools make use of
builtins.buildEnv, but buildEnv is also used in other places. These
places are unrelated to Nix profiles, so the error shouldn't mention
these tools.
This generic error is now BuildEnvFileConflictError, which holds more
contextual information about the files that were conflicting while
building the environment.

Ensure that `self.outPath == ./.`

The reference documentation already implies the correct semantics.

Clean up daemon handling in the tests
|
|
Split `common.sh` into the vars and functions definitions vs starting
the daemon (and possibly other initialization logic). This way,
`init.sh` can just `source` the former. Trying to start the daemon
before `nix.conf` is written will fail because `nix daemon` requires
`--experimental-features 'nix-command'`.
`killDaemon` is idempotent, so it's safe to call when no daemon is
running.
`startDaemon` and `killDaemon` use the PID (which is now exported to
subshells) to decide whether there is work to be done, rather than
`NIX_REMOTE`, which might conceivably be set differently even if a
daemon is running.
`startDaemon` and `killDaemon` can save/restore the old `NIX_REMOTE` as
`NIX_REMOTE_OLD`.
`init.sh` kills daemon before deleting everything (including the daemon
socket).
|

`init.sh` is tested on its own. We used to do that. I deleted it in
4720853129b6866775edd9f90ad6f10701f98a3c but I am not sure why. Better
to just restore it; at one point working on this every other test
passed, so seems good to check whether `init.sh` can be run twice.
We don't *need* to run `init.sh` twice, but I want to try to make our
tests as robust as possible so that manual debugging (where tests for
better or worse might be run ways that we didn't expect) is less
fragile.

build-remote: don't warn when all local build slots are taken

Fix the static build

Remove my CODEOWNER-ship to libstore

It doesn't produce a "debug" output, so the build failed without an
error message in Hydra (https://hydra.nixos.org/build/210121811).

There's only 24 hours in the day, so let's keep things down to a manageable state
|
|
It would be incorrect to say that the `sourceInfo` has an `outPath`
that isn't the root. `sourceInfo` is about the root, whereas only
the flake may not be about the root. Thanks Eelco for pointing that
out.
|
|
Users expect `self` to refer to the directory where the `flake.nix`
file resides.
