Eelco Dolstra b55d79728c Add EvalState::coerceToStorePath() helper
This is useful whenever we want to evaluate something to a store path
(e.g. in get-drvs.cc).

Extracted from the lazy-trees branch (where we can require that a
store path must come from a store source tree accessor).

pennae 41d70a2fc8 return string_views from forceString*
once a string has been forced we already have dynamic storage allocated for it,
so we can easily reuse that storage instead of copying.

forceValue: make pos mandatory
- 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

Eelco Dolstra 6d9a6d2cc3 Ensure that attrsets are sorted
Previously you had to remember to call value->attrs->sort() after
populating value->attrs. Now there is a BindingsBuilder helper that
wraps Bindings and ensures that sort() is called before you can use
it.

John Ericson 255d145ba7 Use BuildableReq for buildPaths and ensurePath
This avoids an ambiguity where the `StorePathWithOutputs { drvPath, {}
}` could mean "build `brvPath`" or "substitute `drvPath`" depending on
context.

It also brings the internals closer in line to the new CLI, by
generalizing the `Buildable` type is used there and makes that
distinction already.

In doing so, relegate `StorePathWithOutputs` to being a type just for
backwards compatibility (CLI and RPC).

John Ericson 32f4454b9f Move StorePathWithOutput utilities out of store class
These are by no means part of the notion of a store, but rather are
things that happen to use stores. (Or put another way, there's no way
we'd make them virtual methods any time soon.) It's better to move them
out of that too-big class then.

Also, this helps us remove StorePathWithOutputs from the Store interface
altogether next commit.

Matthew Bauer 8e0d0689be Only store hash of fixed derivation output
we don’t need a full storepath for a fixedoutput derivation. So just
putting the ingestion method + the hash is sufficient.

John Ericson bcde5456cc Flip dependency so store-api.hh includes derivations.hh
I think it makes more sense to define the data model (derivations),
before the operations (store api).

Eelco Dolstra 54bf5ba422 nix-store -r: Handle symlinks to store paths
Fixes #3270.
2019-12-16 19:11:47 +01:00
Eelco Dolstra bbe97dff8b Make the Store API more type-safe
Most functions now take a StorePath argument rather than a Path (which
is just an alias for std::string). The StorePath constructor ensures
that the path is syntactically correct (i.e. it looks like
<store-dir>/<base32-hash>-<name>). Similarly, functions like
buildPaths() now take a StorePathWithOutputs, rather than abusing Path
by adding a '!<outputs>' suffix.

Note that the StorePath type is implemented in Rust. This involves
some hackery to allow Rust values to be used directly in C++, via a
helper type whose destructor calls the Rust type's drop()
function. The main issue is the dynamic nature of C++ move semantics:
after we have moved a Rust value, we should not call the drop function
on the original value. So when we move a value, we set the original
value to bitwise zero, and the destructor only calls drop() if the
value is not bitwise zero. This should be sufficient for most types.

Also lots of minor cleanups to the C++ API to make it more modern
(e.g. using std::optional and std::string_view in some places).

getDerivations(): Filter out packages with bad derivation names
In particular, this disallows attribute names containing dots or
starting with dots. Hydra already disallowed these. This affects the
following packages in Nixpkgs master:

  2048-in-terminal
  2bwm
  389-ds-base
  90secondportraits
  lispPackages.3bmd
  lispPackages.hu.dwim.asdf
  lispPackages.hu.dwim.def

Closes #1342.

This also gets rid of --log-type, since the nested log type isn't
