Robert Hensing 3384f70a3d nixpkgsLibTests: Only test our Nix
Interface has changed upstream.
It *should* be fine to test 23.05's other Nix versions as those
*should* succeed, but that's not the case and it's obfuscating
our terrible CI setup's log.

John Ericson 5e3986f59c Adapt scheduler to work with dynamic derivations
To avoid dealing with an optional `drvPath` (because we might not know
it yet) everywhere, make an `CreateDerivationAndRealiseGoal`. This goal
just builds/substitutes the derivation file, and then kicks of a build
for that obtained derivation; in other words it does the chaining of
goals when the drv file is missing (as can already be the case) or
computed (new case).

This also means the `getDerivation` state can be removed from
`DerivationGoal`, which makes the `BasicDerivation` / in memory case and
`Derivation` / drv file file case closer together.

The map type is factored out for clarity, and because we will soon hvae
a second use for it (`Derivation` itself).

John Ericson 692074f714 Use Worker::makeDerivationGoal less
We're about to split up `DerivationGoal` a bit. At that point
`makeDerivationGoal` will mean something more specific than it does
today. (Perhaps a future rename will make this clearer.)

On the other hand, the more public `Worker::makeGoal` function will
continue to work exactly as before. So by moving some call sites to use
that instead, we preemptively avoid issues in the next step.

John Ericson fe71faa920 Delete EvalState::addToSearchPath
This function is now trivial enough that it doesn't need to exist.

`EvalState` can still be initialized with a custom search path, but we
don't have a need to mutate the search path after it has been
constructed, and I don't see why we would need to in the future.

John Ericson 9121fed4b4 Fixing
Types converted:

- `NixStringContextElem`
- `OutputsSpec`
- `ExtendedOutputsSpec`
- `DerivationOutput`
- `DerivationType`

Existing ones mostly conforming the pattern cleaned up:

- `ContentAddressMethod`
- `ContentAddressWithReferences`

The `DerivationGoal::derivationType` field had a bogus initialization,
now caught, so I made it `std::optional`. I think  can make it
non-optional again because it will ensure we always have the derivation
when we construct a `DerivationGoal`.

See that issue () for details on the general goal.

`git grep 'Raw::Raw'` indicates the two types I didn't yet convert
`DerivedPath` and `BuiltPath` (and their `Single` variants) . This is
because @roberth and I (can't find issue right now...) plan on reworking
them somewhat, so I didn't want to churn them more just yet.

Cole Helbling 73696ec716 libutil: fix double-encoding of URLs
If you have a URL that needs to be percent-encoded, such as
`http://localhost:8181/test/+3d.tar.gz`, and try to lock that in a Nix
flake such as the following:

    {
      inputs.test = { url = "http://localhost:8181/test/+3d.tar.gz"; flake = false; };
      outputs = { test, ... }: {
        t = builtins.readFile test;
      };
    }

running `nix flake metadata` shows that the input URL has been
incorrectly double-encoded (despite the flake.lock being correctly
encoded only once):

    [...snip...]
    Inputs:
    └───test: http://localhost:8181/test/%252B3d.tar.gz?narHash=sha256-EFUdrtf6Rn0LWIJufrmg8q99aT3jGfLvd1//zaJEufY%3D

(Notice the `%252B`? That's just `%2B` but percent-encoded again)

With this patch, the double-encoding is gone; running `nix flake
metadata` will show the proper URL:

    [...snip...]
    Inputs:
    └───test: http://localhost:8181/test/%2B3d.tar.gz?narHash=sha256-EFUdrtf6Rn0LWIJufrmg8q99aT3jGfLvd1//zaJEufY%3D

---

As far as I can tell, this happens because Nix already percent-encodes
the URL and stores this as the value of `inputs.asdf.url`.

However, when Nix later tries to read this out of the eval state as a
string (via `getStrAttr`), it has to run it through `parseURL` again to
get the `ParsedURL` structure.

Now, this itself isn't a problem -- the true problem arises when using
`ParsedURL::to_string` later, which then _re-escapes the path_. It is
at this point that what would have been `%2B` (`+`) becomes `%252B`
(`%2B`).

Robert Hensing b13fc7101f Add positive source filter
Source filtering is a really cool Nix feature that lets us avoid a
lot of rebuilds, which speeds up the iteration cycle a lot in cases
where the relevant source files aren't actually modified.

We used to have a source filter that marked a few files as irrelevant,
but this is the wrong approach, as we have many more files that are
irrelevant. We may call this negative filtering.

This commit switches the source filtering to positive filtering, which
is a lot more robust. Instead of marking which files we don't need
we marked the files that we do need.

It's a superior approach because it is fail safe. Instead of allowing
build performance problems to creep in over time, we require that all
source inputs are declared.

I shouldn't have to explain that declaring inputs is a good practice,
so I'll stop over-explaining here.

I do have to acknowledge that this will cause a build failure when the
filter is incomplete. This is *good*, because it's the only realistic
way we could be reminded of these problems. These events will be
infrequent, so the small cost of extending the filter is worth it,
compared to the hidden cost of longer dev cycles for things like tests,
docker image, etc, etc.

(Also rebuilding Nix for stupid unnecessary reasons makes my blood boil)

As string sizes are usigned types `(a - b) > 0` effectively means
`a != b`. While the intention should be `a > b`.

The change fixes test suite pass.

Create (experimental) `outputOf` primop.
2023-08-14 16:53:39 +02:00
John Ericson 44c8d83831 Create outputOf primop.
In the Nix language, given a drv path, we should be able to construct
another string referencing to one of its output. We can do this today
with `(import drvPath).output`, but this only works for derivations we
already have.

With dynamic derivations, however, that doesn't work well because the
`drvPath` isn't yet built: importing it like would need to trigger IFD,
when the whole point of this feature is to do "dynamic build graph"
without IFD!

Instead, what we want to do is create a placeholder value with the right
string context to refer to the output of the as-yet unbuilt derivation.
A new primop in the language, analogous to `builtins.placeholder` can be
used to create one. This will achieve all the right properties. The
placeholder machinery also will match out the `outPath` attribute for CA
derivations works.

In 60b7121d2c we added that type of
placeholder, and the derived path and string holder changes necessary to
support it. Then in the previous commit we cleaned up the code
(inspiration finally hit me!) to deduplicate the code and expose exactly
what we need. Now, we can wire up the primop trivally!
