pennae 4d629c4f7a add HAVE_BOEHMGC guards to batched allocation functions 2022-03-09 00:18:50 +01:00
pennae 8e2eaaaf69 make Finally more local
no need for function<> with c++17 deduction. this saves allocations and virtual
calls, but has the same semantics otherwise. not going through function has the
side effect of giving compilers more insight into the cleanup code, so we need a
few local warning disables.

pennae 47baa9d43c make Pos smaller
reduces peak hep memory use on eval of our test system from 264.4MB to 242.3MB,
possibly also a slight performance boost.

theoretically memory use could be cut down by another eight bytes per Pos on
average by turning it into a tuple containing an index into a global base
position table with row and column offsets, but that doesn't seem worth the
effort at this point.

pennae c96460f352 force-inline a few much-used functions
these functions are called a whole lot, and they're all comparatively small.
always inlining them gives ~0.7% performance boost on eval.

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.

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.

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.
