Get rid of most .at calls (#6393)
Use one of `get` or `getOr` instead which will either return a null-pointer (with a nicer error message) or a default value when the key is missing.

libfetchers/git: fix every occasion of a permission error
I'm afraid I missed a few problematic `git(1)`-calls while implementing
PR #6440, sorry for that! Upon investigating what went wrong, I realized
that I only tested against the "cached"-case by accident because my
git-checkout with my system's flake was apparently cached during my
debugging.

I managed to trigger the original issue again by running:

    $ git commit --allow-empty -m "tmp"
    $ sudo nixos-rebuild switch --flake .# -L --builders ''

Since `repoDir` points to the checkout that's potentially owned by
another user, I decided to add `--git-dir` to each call affecting
`repoDir`.

Since the `tmpDir` for the temporary submodule-checkout is created by
Nix itself, it doesn't seem to be an issue.

Sorry for that, it should be fine now.

setting the HEAD ref in the local cache appropriately.

Eelco Dolstra 1ddabe1a01 nix: Respect meta.outputsToInstall, and use all outputs by default
'nix profile install' will now install all outputs listed in the
package's meta.outputsToInstall attribute, or all outputs if that
attribute doesn't exist. This makes it behave consistently with
nix-env. Fixes #6385.

Furthermore, for consistency, all other 'nix' commands do this as
well. E.g. 'nix build' will build and symlink the outputs in
meta.outputsToInstall, defaulting to all outputs. Previously, it only
built/symlinked the first output. Note that this means that selecting
a specific output using attrpath selection (e.g. 'nix build
nixpkgs#libxml2.dev') no longer works. A subsequent PR will add a way
to specify the desired outputs explicitly.

Eelco Dolstra 29e52194a8 Merge branch 'symbolidx-symbol' of https://github.com/pennae/nix 2022-04-26 13:25:10 +02:00
pennae a385e51a08 rename SymbolIdx -> Symbol, Symbol -> SymbolStr
after #6218 `Symbol` no longer confers a uniqueness invariant on the
string it wraps, it is now possible to create multiple symbols that
compare equal but whose string contents have different addresses. this
guarantee is now only provided by `SymbolIdx`, leaving `Symbol` only as
a string wrapper that knows about the intricacies of how symbols need to
be formatted for output.

this change renames `SymbolIdx` to `Symbol` to restore the previous
semantics of `Symbol` to that name. we also keep the wrapper type and
rename it to `SymbolStr` instead of returning plain strings from lookups
into the symbol table because symbols are formatted for output in many
places. theoretically we do not need `SymbolStr`, only a function that
formats a string for output as a symbol, but having to wrap every symbol
that appears in a message into eg `formatSymbol()` is error-prone and
inconvient.

libfetchers/git: fix for nixos-rebuild
The `--git-dir=` must be `.` in some cases (for cached repos that are
"bare" repos in `~/.cache/nix/gitv3`). With this fix we can add
`--git-dir` to each `git`-invokation needed for `nixos-rebuild`.

libfetchers/git: hardcode --git-dir
To demonstrate the problem:

* You need a `git` at 2.33.3 in your $PATH
* An expression like this in a git repository:

  ``` nix
  {
    outputs = { self, nixpkgs }: {
      packages.foo.x86_64-linux = with nixpkgs.legacyPackages.x86_64-linux;
        runCommand "snens" { } ''
          echo ${(builtins.fetchGit ./.).lastModifiedDate} > $out
        '';
    };
  }
  ```

Now, when instantiating the package via `builtins.getFlake`, it fails on
Nix 2.7 like this:

    $ nix-instantiate -E '(builtins.getFlake "'"$(pwd)"'").packages.foo.x86_64-linux'
    fatal: unsafe repository ('/nix/store/a7j3125km4h8l0p71q6ssfkxamfh5d61-source' is owned by someone else)
    To add an exception for this directory, call:

    	git config --global --add safe.directory /nix/store/a7j3125km4h8l0p71q6ssfkxamfh5d61-source
    error: program 'git' failed with exit code 128
    (use '--show-trace' to show detailed location information)

This breaks e.g. `nixops`-deployments using flakes with similar
expressions as shown above.

The cause for this is that `git(1)` tries to find the highest
`.git`-directory in the directory tree and if it finds a such a
directory, but with another owning user (root vs. the user who evaluates
the expression), it fails as above. This was changed recently to fix
CVE-2022-24765[1].

By explicitly specifying `--git-dir`, Git assumes to be in the top-level
directory and doesn't attempt to look for a `.git`-directory in the
parent directories and thus the code-path leading to said error is never
reached.
