2021-09-30`std::visit` by referenceJohn Ericson
I had started the trend of doing `std::visit` by value (because a type error once mislead me into thinking that was the only form that existed). While the optomizer in principle should be able to deal with extra coppying or extra indirection once the lambdas inlined, sticking with by reference is the conventional default. I hope this might even improve performance.
2021-07-22Use eval-store in more placesEelco Dolstra
In particular, this now works: $ nix path-info --eval-store auto --store https://cache.nixos.org nixpkgs#hello Previously this would fail as it would try to upload the hello .drv to cache.nixos.org. Now the .drv is instantiated in the local store, and then we check for the existence of the outputs in cache.nixos.org.
2021-04-05Move `StorePathWithOutputs` into its own header/fileJohn Ericson
In the following commits it will become less prevalent.
2021-02-26Simplify the case where the drv is a purely input-addressed oneregnat
2021-02-19Remove the drv resolution caching mechanismregnat
It isn't needed anymore now that don't need to eagerly resolve everything like we used to do. So we can safely get rid of it
2021-02-19Don't expose the "bang" drvoutput syntaxThéophane Hufschmitt
It's not fixed nor useful atm, so better keep it hidden Co-authored-by: Eelco Dolstra <edolstra@gmail.com>

2021-02-19Register the realisations for unresolved drvsregnat
Once a build is done, get back to the original derivation, and register all the newly built outputs for this derivation. This allows Nix to work properly with derivations that don't have all their build inputs available − thus allowing garbage collection and (once it's implemented) binary substitution
2020-12-17Fix the detection of already built drv outputsregnat
PRs #4370 and #4348 had a bad interaction in that the second broke the fist one in a not trivial way. The issue was that since #4348 the logic for detecting whether a derivation output is already built requires some logic that was specific to the `LocalStore`. It happens though that most of this logic could be upstreamed to any `Store`, which is what this commit does.
2020-12-11Use the hash modulo in the derivation outputsregnat
Rather than storing the derivation outputs as `drvPath!outputName` internally, store them as `drvHashModulo!outputName` (or `outputHash!outputName` for fixed-output derivations). This makes the storage slightly more opaque, but enables an earlier cutoff in cases where a fixed-output dependency changes (but keeps the same output hash) − same as what we already do for input-addressed derivations.
2020-11-19Make drv hash modulo memo table thread-safeJohn Ericson
Let's get one step closer to the daemon not needing to fork.

2020-09-15Rename `Derivation::pathOpt` to `Derivation::path`John Ericson
We no longer need the `*Opt` to disambiguate.
2020-09-04Fix querying outputs for CA derivations some moreJohn Ericson
If we resolve using the known path of a derivation whose output we didn't have, we previously blew up. Now we just fail gracefully, returning the map of all outputs unknown.
2020-09-04Fix floating CA testsJohn Ericson
We will sometimes try to query the outputs of derivations we can't resolve. That's fine; it just means we don't know what those outputs are yet.
