Tom Bereknyei d77823b502 bundler: update default bundler to support new bundler API 2022-03-30 16:10:42 -04:00
Théophane Hufschmitt 390269ed87 Simplify the handling of the hash modulo
Rather than having four different but very similar types of hashes, make
only one, with a tag indicating whether it corresponds to a regular of
deferred derivation.

This implies a slight logical change: The original Nix+multiple-outputs
model assumed only one hash-modulo per derivation. Adding
multiple-outputs CA derivations changed this as these have one
hash-modulo per output. This change is now treating each derivation as
having one hash modulo per output.
This obviously means that we internally loose the guaranty that
all the outputs of input-addressed derivations have the same hash
modulo. But it turns out that it doesn’t matter because there’s nothing
in the code taking advantage of that fact (and it probably shouldn’t
anyways).

The upside is that it is now much easier to work with these hashes, and
we can get rid of a lot of useless `std::visit{ overloaded`.

Eelco Dolstra 057f9ee190 nix profile install: Don't use queryDerivationOutputMap()
Instead get the outputs from Installable::build(). This will also
allow 'nix profile install' to support impure derivations.

polykernel cbcb69a39c nix: allow whitespace characters before command in repl
Before this change, processLine always uses the first character
as the start of the line. This cause whitespaces to matter at the
beginning of the line whereas it does not matter anywhere else.

This commit trims leading white spaces of the string line so that
subsequent operations can be performed on the string without explicitly
tracking starting and ending indices of the string.

Eelco Dolstra 540d7e33d8 Retry substitution after an incomplete closure only once
This avoids an infinite loop in the final test in

by accident (because we were clearing wantedOutputs in between).

Eelco Dolstra f18607549c Fix makeContentAddressed() on self-references
LocalStore::addToStore() since
79ae9e4558 expects a regular NAR hash,
rather than a NAR hash modulo self-references. Fixes #6300.

Also, makeContentAddressed() now rewrites the entire closure (so 'nix
store make-content-addressable' no longer needs '-r'). See #6301.

Sergei Trofimovich 9174d884d7 lexer: add error location to lexer errors
Before the change lexter errors did not report the location:

    $ nix build -f. mc
    error: path has a trailing slash
    (use '--show-trace' to show detailed location information)

Note that it's not clear what file generates the error.

After the change location is reported:

    $ src/nix/nix --extra-experimental-features nix-command build -f ~/nm mc
    error: path has a trailing slash

           at .../pkgs/development/libraries/glib/default.nix:54:18:

               53|   };
               54|   src = /tmp/foo/;
                 |                  ^
               55|
    (use '--show-trace' to show detailed location information)

Here we see both problematic file and the string itself.

John Ericson 197feed51d Clean up DerivationOutput, and headers
1. `DerivationOutput` now as the `std::variant` as a base class. And the
   variants are given hierarchical names under `DerivationOutput`.

   In 8e0d0689be @matthewbauer and I
   didn't know a better idiom, and so we made it a field. But this sort
   of "newtype" is anoying for literals downstream.

   Since then we leaned the base class, inherit the constructors trick,
   e.g. used in `DerivedPath`. Switching to use that makes this more
   ergonomic, and consistent.

2. `store-api.hh` and `derivations.hh` are now independent.

   In bcde5456cc I swapped the dependency,
   but I now know it is better to just keep on using incomplete types as
   much as possible for faster compilation and good separation of
   concerns.

Sergei Trofimovich d58453f72e gc: don't visit implicit referrers on garbage collection
Before the change garbage collector was not considering
`.drv` and outputs as alive even if configuration says otherwise.
As a result `nix store gc --dry-run` could visit (and parse)
`.drv` files multiple times (worst case it's quadratic).

It happens because `alive` set was populating only runtime closure
without regard for actual configuration. The change fixes it.

Benchmark: my system has about 139MB, 40K `.drv` files.

Performance before the change:

    $ time nix store gc --dry-run
    real    4m22,148s

Performance after the change:

    $ time nix store gc --dry-run
    real    0m14,178s
