Starting from c436b7a32a
this used to lead to assertion failures like:
> std::string nix::ParsedURL::renderAuthorityAndPath() const: Assertion `path.empty() || path.front().empty()' failed.
This has the bugfix for the issue and regressions tests
so that this gets properly tested in the future.
This would print erroneous and misleading diagnostics like:
> error (ignored): error: '--arg' and '--argstr' are incompatible with flakes
When run with --expr/--file. Since this installable is used to get the
bash package it doesn't make sense to check this.
Now we have better separation of the core logic --- an integral part of
the store layer spec even --- from the goal mechanism and other
minutiae.

See the new extensive doxygen in `url.hh`.
This fixes fetching gitlab: flakes.
Paths are now stored as a std::vector of individual path
segments, which can themselves contain path separators '/' (%2F).
This is necessary to make the Gitlab's /projects/ API work.

Instead of passing them around separately, or doing finicky logic in a
try-catch block to recover them, just make `BuildError` always contain a
status, and make it the thrower's responsibility to set it. This is much
more simple and explicit.
Once that change is done, split the `done` functions of `DerivationGoal`
and `DerivationBuildingGoal` into separate success and failure
functions, which ends up being easier to understand and hardly any
duplication.
Also, change the handling of failures in resolved cases to use
`BuildResult::DependencyFailed` and a new message. This is because the
underlying derivation will also get its message printed --- which is
good, because in general the resolved derivation is not unique. One dyn
drv test had to be updated, but CA (and dyn drv) is experimental, so I
do not mind.
Finally, delete `SubstError` because it is unused.
The commit says it was added for CA testing --- manual I assume, since
there is no use of this in the test suite. I don't think we need it any
more, and I am not sure whether it was ever supposed to have made it to
`master` either.
This reverts commit 2eec2f765a.
We currently just use this during the build of a derivation, but there is no
reason we wouldn't want to use it elsewhere, e.g. to check the outputs
of someone else's build after the fact.
Moreover, I like pulling things out of `DerivationBuilder` that are
simple and don't need access to all that state. While
`DerivationBuilder` is unix-only, this refactor also make the code more
portable "for free".
The header is private, at Eelco's request.
This allows us to replace some very hacky and not correct string
concatentation in `HttpBinaryCacheStore`. It will especially be useful
with #13752, when today's hacks started to cause problems in practice,
not just theory.
Also make `fixGitURL` returned a `ParsedURL`.

This update contains d1266642a8722f2a05e311fa151c1413d2b9653c, which
is necessary for the TOML timestamps to get tested via nixpkgsLibTests job.
I need this for some `ParseURL` improvements, but I figure this is
better to send as its own PR.
I changed the tests willy-nilly to sometimes use
`std::list<std::string_view>` instead of `Strings` (which is
`std::list<std::string>`).

It is suppposed to be "post build" not "during the build" after all. Its
location now matches that for the hook case (see elsewhere in
`DerivationdBuildingGoal`).
It was in a try-catch before, and now it isn't, but I believe that it is
impossible for it to throw `BuildError`, which is sufficient for this
code motion to be correct.
