jade 43cf487c25 Create clang-tidy check to rename all our includes
It is a little bit scuffed, but it seems to produce correct results. We
can run it at a later date when we want to explode every in-flight
commit in existence and then need to filter-branch them.

Fixes: lix-project/lix#188

Qyriad a4ef195a9f always re-eval cached failures
This is terrible UX, and frankly an eval failure should be a cache
invalidation anyway.

This removes the CachedEvalError type entirely.

Fixes #223.

Qyriad 11ad383327 package: add python to nativeBuildInputs
Commit c21d11ac0 "docs: replace sed invocation with an mdbook
preprocessor for @docroot@" added a direct build dependency on Python.
This has been accidentally working so far because Python is already a
*transitive* dependency of Lix's derivation.

Rebecca Turner ee423f391d Rewrite REPL test parser
- Use a recursive descent parser so that it's easy to extend.
- Add `@args` to enable customizing command-line arguments
- Add `@should-start` to enable `nix repl` tests that error before
  entering the REPL
- Make sure to read all stdout output before comparing. This catches
  some extra output we were tossing out before!

This reverts commit 491caad6f62c21ffbcdebe662e63ec0f72e6f3a2.

this is not actually legal for nix! throwing exceptions in destructors
is fine, but the way nix is set up we'll end up throwing the exception
we received from the remote *twice* in some cases, and such cases will
cause an immediate terminate without active exception.

eldritch horrors 6c777476c9 libutil: guard Finally against invalid exception throws
throwing exceptions is fine, but throwing exceptions during exception
handling is hard enough to do correctly that we should just forbid it
entirely out of an overabundance of caution. in cases where terminate
is the correct answer the users of Finally must call it manually now.

Qyriad c355354772 docs: replace sed invocation with an mdbook preprocessor for @docroot@
We're not entirely clear on why the links preprocessor has to be done
*before* rather than after, but we assume it is probably that as a
builtin preprocessor it does some processing on the raw book source,
and not just the JSON data.

Also a real use for Python pattern matching? I know I was surprised too.

Lunaphied 7a1054fa5f repl: improve :doc builtin repl command to support lambdas.
For a long time `nix repl` has supported displaying documentation set on
builtins, however, it has long been convention to use Markdown comments
on Nix functions themselves for documentation. This exposes that
information to `nix repl` users in a nice and formatted way.

NixOS/rfcs#145 doc-comments are primarily what this feature is intended
to consume, however, support for lambda documentation in the repl is
experimental. We do our best effort to support the RFC here.

These changes are based on [the nix-doc library](https://github.com/lf-/nix-doc) and
are licensed under the terms described in the relevant source files.

eldritch horrors 45623f077f libutil: drop Fs{Source,Sink}::good
setting this only on exceptions caused by actual fd access is not
sufficient to diagnose all errors (such as SerialisationError) in
some cases. this usually does not have any negative effects since
those errors will end up killing the process in another way. this
is not a reliable assumption though and we should be using proper
error handling (and closing connections more often, preferring to
close over keeping something open that might be in a weird state)

eldritch horrors f402c45cfa libutil: allow graceful dropping of Pool::Handle
not needed yet, but returning a resource from the exception handling
path that has ownership of a handle is currently not well-supported.
we could also add a default constructor to Handle, but then we would
also need to change the pool reference to a pointer. eventually that
should be done since now resources can be swapped between pools with
clever moves, but since that's not a problem yet we won't do it now.

eldritch horrors dd06f9b792 libutil: make ~Finally noexcept(false)
this is supposed to act like a finally block does in other languages. a
finally block should be able to throw exceptions of its own rather than
just crashing the entire program when it throws it own exceptions. even
in the rare case of a finally throwing an unexpected exception it might
be better to report the exception from Finally instead of the original,
at least that can keep our program running instead of letting it crash.

if a scope owning a resource does not gracefully drop that resource
while handling exceptions from deeper down the call stack we should
assume the resource is invalid state and drop it. currently it *is*
true that such cases do not cause resources to be freed, but thanks
to validator misuses this has so far not caused any larger problem.
