Also use std::string_view in a few more places.

2022-01-27optionally return string_view from coerceToStringpennae
we'll retain the old coerceToString interface that returns a string, but callers that don't need the returned value to outlive the Value it came from can save copies by using the new interface instead. for values that weren't stringy we'll pass a new buffer argument that'll be used for storage and shouldn't be inspected.
2022-01-21forceAttrs: make pos mandatoryKevin Amado
2022-01-21forceValue: make pos mandatoryKevin Amado
- Make passing the position to `forceValue` mandatory, this way we remember people that the position is important for better error messages - Add pos to all `forceValue` calls

improve parser performance a bit
2022-01-13avoid copies of parser input datapennae
when given a string yacc will copy the entire input to a newly allocated location so that it can add a second terminating NUL byte. since the parser is a very internal thing to EvalState we can ensure that having two terminating NUL bytes is always possible without copying, and have the parser itself merely check that the expected NULs are present. # before Benchmark 1: nix search --offline nixpkgs hello Time (mean ± σ): 572.4 ms ± 2.3 ms [User: 563.4 ms, System: 8.6 ms] Range (min … max): 566.9 ms … 579.1 ms 50 runs Benchmark 2: nix eval -f ../nixpkgs/pkgs/development/haskell-modules/hackage-packages.nix Time (mean ± σ): 381.7 ms ± 1.0 ms [User: 348.3 ms, System: 33.1 ms] Range (min … max): 380.2 ms … 387.7 ms 50 runs Benchmark 3: nix eval --raw --impure --expr 'with import <nixpkgs/nixos> {}; system' Time (mean ± σ): 2.936 s ± 0.005 s [User: 2.715 s, System: 0.221 s] Range (min … max): 2.923 s … 2.946 s 50 runs # after Benchmark 1: nix search --offline nixpkgs hello Time (mean ± σ): 571.7 ms ± 2.4 ms [User: 563.3 ms, System: 8.0 ms] Range (min … max): 566.7 ms … 579.7 ms 50 runs Benchmark 2: nix eval -f ../nixpkgs/pkgs/development/haskell-modules/hackage-packages.nix Time (mean ± σ): 376.6 ms ± 1.0 ms [User: 345.8 ms, System: 30.5 ms] Range (min … max): 374.5 ms … 379.1 ms 50 runs Benchmark 3: nix eval --raw --impure --expr 'with import <nixpkgs/nixos> {}; system' Time (mean ± σ): 2.922 s ± 0.006 s [User: 2.707 s, System: 0.215 s] Range (min … max): 2.906 s … 2.934 s 50 runs

2021-12-27Fix accidental O(n^2 * log n) performance in NixRepl::addAttrsToScopeYorick van Pelt
Only sort once, after adding all of the attrs first. This reduces my `nix repl '<nixpkgs>'` loading time from 1.07s to 103ms. Fixes #5823
2021-12-22Remove CPU lockingEelco Dolstra
This was already accidentally disabled in ba87b08. It also no longer appears to be beneficial, and in fact slow things down, e.g. when evaluating a NixOS system configuration: elapsed time: median = 3.8170 mean = 3.8202 stddev = 0.0195 min = 3.7894 max = 3.8600 [rejected, p=0.00000, Δ=0.36929±0.02513]

2021-11-05Fix `nix repl`’s building of CA derivationsregnat

2021-10-07nix repl: properly deal with interruptionsMaximilian Bosch
When I stop a download with Ctrl-C in a `nix repl` of a flake, the REPL refuses to do any other downloads: nix-repl> builtins.getFlake "nix-serve" [0.0 MiB DL] downloading 'https://api.github.com/repos/edolstra/nix-serve/tarball/e9828a9e01a14297d15ca41 error: download of 'https://api.github.com/repos/edolstra/nix-serve/tarball/e9828a9e01a14297d15ca416e5a9415d4972b0f0' was interrupted [0.0 MiB DL] nix-repl> builtins.getFlake "nix-serve" error: interrupted by the user [0.0 MiB DL] To fix this issue, two changes were necessary: * Reset the global `_isInterrupted` variable: only because a single operation was aborted, it should still be possible to continue the session. * Recreate a `fileTransfer`-instance if the current one was shut down by an abort.

2021-07-19nix repl: Update :edit help textRobert Hensing
It supports functions as well. Also change `package` to `derivation` because it operates at the language level and does not open the derivation (which would be useful but not nearly as much).
2021-07-19Rename findDerivationFilename -> findPackageFilenameRobert Hensing
It does not operate on a derivation and does not return a derivation path. Instead it works at the language level, where a distinct term "package" is more appropriate to distinguish the parent object of `meta.position`; an attribute which doesn't even make it into the derivation.
2021-07-19Add a `:load-flake` command to the nix replregnat
`:lf ref` does essentially the same thing as `:a (builtins.getFlake "ref")` (but cannonicalising `ref` if needs be, so that `:lf .` works) Fix #3803
2021-07-16Forward the whole Nix config to the repl subprocessesregnat
Fill `NIX_CONFIG` with the value of the current Nix configuration before calling the nix subprocesses in the repl That way the whole configuration (including the possible `experimental-features`, a possibly `--store` option or whatever) will be made available. This is required for example to make `nix repl` work with a custom `--store`
2021-06-29Forward the experimental features to the nix repl subprocessesregnat
Pass the current experimental features using `NIX_CONFIG` to the various Nix subprocesses that `nix repl` invokes. This is quite a hack, but having `nix repl` call Nix with a subprocess is a hack already, so I guess that’s fine.
