2022-02-25Remove std::string alias (for real this time)Eelco Dolstra
Also use std::string_view in a few more places.
2022-01-27return string_views from forceString*pennae
once a string has been forced we already have dynamic storage allocated for it, so we can easily reuse that storage instead of copying.
2021-09-10Remove tabsEelco Dolstra
2021-03-17Remove unimplemented hashAlgoOptRobert Hensing
It was in the header but never implemented.
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
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.

2020-09-28Clarify comment a bitJohn Ericson
2020-09-16Ensure resolved CA derivations are writtenJohn Ericson
so we can link outputs to deriver and thus properly cache.

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.

- More and better comments - The easier renames
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.
