Eelco Dolstra a4604f1928 Add Store::buildPathsWithResults()
This function is like buildPaths(), except that it returns a vector of
BuildResults containing the exact statuses and output paths of each
derivation / substitution. This is convenient for functions like
Installable::build(), because they then don't need to do another
series of calls to get the outputs of CA derivations. It's also a
precondition to impure derivations, where we *can't* query the output
of those derivations since they're not stored in the Nix database.

Note that PathSubstitutionGoal can now also return a BuildStatus.

regnat f6078e474d Also display some suggestions for invalid formal arguments
```console
$ nix eval --expr '({ foo ? 1 }: foo) { fob = 2; }'
error: anonymous function at (string):1:2 called with unexpected argument 'fob'

       at «string»:1:1:

            1| ({ foo ? 1 }: foo) { fob = 2; }
             | ^
       Did you mean foo?
```

Not that because Nix will first check for _missing_ arguments before
checking for extra arguments, `({ foo }: foo) { fob = 1; }` will
complain about the missing `foo` argument (rather than extra `fob`) and
so won’t display a suggestion.

Make the evaluator show some suggestions when trying to access an
invalid field from an attrset.

```console
$ nix eval --expr '{ foo = 1; }.foa'
error: attribute 'foa' missing

       at «string»:1:1:

            1| { foo = 1; }.foa
             | ^
       Did you mean foo?

regnat dcf4f77fac Merge or-suggestions.hh into suggestions.hh
No real need for keeping a separate header for such a simple class.

This requires changing a bit `OrSuggestions<T>::operator*` to not throw
an `Error` to prevent a cyclic dependency. But since this error is only
thrown on programmer error, we can replace the whole method by a direct
call to `std::get` which will raise its own assertion if needs be.

Robert Hensing da260f579d dupStringWithLen -> makeImmutableString
Refactor the `size == 0` logic into a new helper function that
replaces dupStringWithLen.
The name had to change, because unlike a `dup`-function, it does
not always allocate a new string.

Factor out a `GcStore` interface
2022-03-03 20:53:10 +01:00
John Ericson 6636202356 Factor out a GcStore interface
Starts progress on #5729.

The idea is that we should not have these default methods throwing
"unimplemented". This is a small step in that direction.

I kept `addTempRoot` because it is a no-op, rather than failure. Also,
as a practical matter, it is called all over the place, while doing
other tasks, so the downcasting would be annoying.

Maybe in the future I could move the "real" `addTempRoot` to `GcStore`,
and the existing usecases use a `tryAddTempRoot` wrapper to downcast or
do nothing, but I wasn't sure whether that was a good idea so with a
bias to less churn I didn't do it yet.

Eelco Dolstra b55d79728c Add EvalState::coerceToStorePath() helper
This is useful whenever we want to evaluate something to a store path
(e.g. in get-drvs.cc).

Extracted from the lazy-trees branch (where we can require that a
store path must come from a store source tree accessor).

  nix-daemon: src/libstore/sqlite.cc:97: nix::SQLiteStmt::Use::Use(nix::SQLiteStmt&): Assertion `stmt.stmt' failed.

which happens because the daemon doesn't properly handle the case
