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.

Let's get one step closer to the daemon not needing to fork.

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.

The new interface we offer provides a way of getting all the DerivationOutputs with the storePaths directly, based on the observation that it's the most common usecase.

2020-07-23Get rid of `basicDerivation::findOutput`John Ericson
It's a tiny function which is: - hardly worth abstrating over, and also only used once. - doesn't work once we get CA drvs I rewrote the one callsite to be forwards compatable with CA derivations, and also potentially more performant: instead of reading in the derivation it can ust consult the SQLite DB in the common case.

2020-07-12Change types to prepare the way for CA derivationsJohn Ericson
We've added the variant to `DerivationOutput` to support them, but made `DerivationOutput::path` partial to avoid actually implementing them. With this chage, we can all collaborate on "just" removing `DerivationOutput::path` calls to implement CA derivations.
2020-07-12Use more std::visit to prepare for new variantJohn Ericson
N.B. not using `std::visit` for fetchurl because there is no attempt to handle all the cases (e.g. no `else`) and lambda complicates early return.

we don’t need a full storepath for a fixedoutput derivation. So just putting the ingestion method + the hash is sufficient.
