John Ericson f419ab48e6 Try to fix build failure 
Failure: https://hydra.nixos.org/build/205357257/nixlog/1

The problem seems to be trying to `std::visit` a derived class of
`std::variant`. Per
https://stackoverflow.com/questions/63616709/incomplete-type-stdvariant-used-in-nested-name-specifier
certain C++ standard library implementations allow this, but others do
not.

The solution is simply to call the `raw` method, which upcasts the
reference back to the `std::variant`.

John Ericson a416476217 Move ValidPathInfo defintions to path-info.cc 
Originally there was no `path-info.*`, then there was `path-info.hh`,
then there was `path-info.cc`, but only for new things. Moving this
stuff over makes everything consistent.

John Ericson 5ba6e5d0d9 Remove default constructor from OutputsSpec 
This forces us to be explicit.

It also requires to rework how `from_json` works. A `JSON_IMPL` is added
to assist with this.

John Ericson 114a6e2b09 Make it hard to construct an empty OutputsSpec::Names 
This should be a non-empty set, and so we don't want people doing this
by accident. We remove the zero-0 constructor with a little inheritance
trickery.

John Ericson ce2f91d356 Split OutputsSpec and ExtendedOutputsSpec, use the former more 
`DerivedPath::Built` and `DerivationGoal` were previously using a
regular set with the convention that the empty set means all outputs.
But it is easy to forget about this rule when processing those sets.
Using `OutputSpec` forces us to get it right.
 2023-01-11 18:57:18 -05:00

Eelco Dolstra 9fc8d00d74 MonitorFdHup: Make it work on macOS again 
It appears that on current macOS versions, our use of poll() to detect
client disconnects no longer works. As a workaround, poll() for
POLLRDNORM, since this *will* wake up when the client has
disconnected. The downside is that it also wakes up when input is
available. So just sleep for a bit in that case.  This means that on
macOS, a client disconnect may take up to a second to be detected,
but that's better than not being detected at all.

Fixes #7584.

mdbook-linkcheck is not consistent about its warning setting.

John Ericson 5576d5e987 Parse string context elements properly 
Prior to this change, we had a bunch of ad-hoc string manipulation code
scattered around. This made it hard to figure out what data model for
string contexts is.

Now, we still store string contexts most of the time as encoded strings
--- I was wary of the performance implications of changing that --- but
whenever we parse them we do so only through the
`NixStringContextElem::parse` method, which handles all cases. This
creates a data type that is very similar to `DerivedPath` but:

 - Represents the funky `=<drvpath>` case as properly distinct from the
   others.

 - Only encodes a single output, no wildcards and no set, for the
   "built" case.

(I would like to deprecate `=<path>`, after which we are in spitting
distance of `DerivedPath` and could maybe get away with fewer types, but
that is another topic for another day.)
 2023-01-10 13:10:49 -05:00
John Ericson da64f026dd Make clear that StorePathWithOutputs is a deprecated type 
- Add a comment

- Put `OutputsSpec` in a different header (First part of #6815)

- Make a few stray uses of it in new code use `DerivedPath` instead.
