18935e8b9f Support fixed-output derivations depending on impure derivations 2022-03-31 13:43:20 +02:00
Eelco Dolstra
5cd72598fe Add support for impure derivations
Impure derivations are derivations that can produce a different result
every time they're built. Example:

  stdenv.mkDerivation {
    name = "impure";
    __impure = true; # marks this derivation as impure
    outputHashAlgo = "sha256";
    outputHashMode = "recursive";
    buildCommand = "date > $out";
  };

Some important characteristics:

* This requires the 'impure-derivations' experimental feature.

* Impure derivations are not "cached". Thus, running "nix-build" on
  the example above multiple times will cause a rebuild every time.

* They are implemented similar to CA derivations, i.e. the output is
  moved to a content-addressed path in the store. The difference is
  that we don't register a realisation in the Nix database.

* Pure derivations are not allowed to depend on impure derivations. In
  the future fixed-output derivations will be allowed to depend on
  impure derivations, thus forming an "impurity barrier" in the
  dependency graph.

* When sandboxing is enabled, impure derivations can access the
  network in the same way as fixed-output derivations. In relaxed
  sandboxing mode, they can access the local filesystem.

629edd43ba libutil: Change return value of addTrace to void
The return value of BaseError::addTrace(...) is never used and
error-prone as subclasses calling it will return a BaseError instead of
the subclass.
This commit changes its return value to be void.

BaseError::addTrace(...) returns a BaseError, but we want to
throw a TypeError instead.

nix-daemon.service: require mounts for /nix/var/nix/db
Users may want to mount a filesystem just for the Nix database, with
the filesystem's parameters specially tuned for sqlite. For example, on
ZFS you might set the recordsize to 64k after changing the database's
page size to 65536.

Merge pull request #6268 from thufschmitt/remove-the-variant-in-hashmodulo
Simplify the handling of the hash modulo
2022-03-29 20:26:47 +02:00
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`.

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.

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.

This avoids an infinite loop in the final test in

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