Starting to reclaim memory. Fairly simple mechanical replacement.

Introduces the actual log sink in several places where we actually
want the build logs to thread through correctly.
This should cover *most* build paths.

This part of the store API needs to carry a handle to the log sink
from now on, so that it can be passed in as appropriate from the gRPC
handlers.
In all places where there is no such handler available at the moment,
the discarding log sink has been inserted. This can be used as a
convenient grep target in the future.

Previously the outlist would not be used, and it would sort god knows
what in the out value.
This was probably introduced by the std::vector refactoring, and the
language test for builtins.sort was disabled. Whatever reason there
was for disabling it seems to be gone, so we're re-enabling it.

Make Store::buildPaths return a Status with [[nodiscard]] rather than
throwing exceptions to signal failure. This is the beginning of a long
road to refactor the entire store API to be status/statusor based
instead of using exceptions.

We have decided that leaking memory is a better fate than random,
non-debuggable memory corruption. Future CLs will begin changing
various fields to std::unique_ptr and std::shared_ptr.
It turns out that disabling the GC does not have disasterous impact.
The Nix evaluator only runs on the client CLI, never in any long-
running process. Even the REPL does not leak too badly under this
change, because it uses one EvalState for the duration of the REPL.
Building an explicitly tracing garbage collector is likely in the
future of this project, but that giant amount of work cannot be
done under a nix evaluator that is constantly crashing. We need to
restore development velocity here, and this is the best way we've
figured out to do it.

The behavior to return a list containing a single empty string when
provided an empty string is a behavior that absl inherited from legacy
code. However, the behavior expected by legacy code in Nix is the
behavior provided by the SkipEmpty option. Switch all calls to use
SkipEmpty, except for the call already using SkipWhitespace.

partly-prophetic message: "there may be other places we need to

This is the shared object equivalent of builtins.exec, or a plugins
equivalent accessible from the Nix language. Either way, since we
don't have builtins.exec or plugins any more, I think it makes sense
to remove this builtin.
This will also allow us to drop the
allow-unsafe-native-code-during-evaluation option, which formerly
controlled whether builtins.exec and builtins.importNative were
enabled.

This compiles under `-Wall -Werror`.
The largest chunk of this change is `final` qualifiers for the various
Nix CLI command structs, which inherit from a Command class that has
more virtual functions than are implemented by each command.

This change does away with the previous special-casing of lists of
certain element sizes, and the use of raw C-style arrays.
Lists are now backed by a std::vector of nix::Value*, which uses the
traceable GC allocator.
This change is unfortunately quite noisy because the accessor methods
were updated/removed accordingly, so all callsites of Nix-related
lists have changed.
For some operations in primops.cc where keeping the previous code
structure would have been more difficult with a "proper" vector, the
implementation has been replaced with std::vector methods. For
example, list concatenation now uses appropriate range inserts.
Anecdotally the performance of this is about equal, to even slightly
better, than the previous implementation.
All language tests pass and the depot paths I've used for testing
still evaluate.

Having a default constructor for this causes a variety of annoying
situations across the codebase in which this is initialised to an
unexpected value, leading to constant guarding against those
conditions.
It turns out there's actually no intrinsic reason that this default
constructor needs to exist. The biggest one was addressed in CL/1138
and this commit cleans up the remaining bits.

Previously all includes were anchored in one global mess of header
files. This moves the includes into filesystem "namespaces" (if you
will) for each sub-package of Nix.
Note: This commit does not introduce the relevant build system changes.
|
|
This function was a custom (and inefficient in the case of
single-character delimiters) string splitter which was used all over
the codebase. Abseil provides an appropriate replacement function.
|
|
It is considered bad form to use things from includes in headers, as
these directives propagate to everywhere else and can make it
confusing.
types.hh (which is includes almost literally everywhere) had some of
these directives, which this commit removes.
|
|
Replaces the previous implementations which performed sorting with one
that instead walks through the map (which is already sorted) and
yields values from it.
This fixes a handful of language tests because the previous
implementation did not actually yield useful values on the new implementation.
|
|
This function does nothing anymore since the attributes are always
in-order.
|
|
The new attribute set API uses the iterators of the btree_map
directly. This requires changes in various files because the internals
of libexpr are very entangled.
This code runs and compiles, but there is a bug causing empty
attribute sets to be assigned incorrectly.
|
|
Replaces most uses of `string` with `std::string`.
This came up because I removed the "types.hh" import from
"symbol-table.hh", which percolated through a bunch of files where
`string` was suddenly no longer defined ... *sigh*
|
|
The functions in SymbolTable have been renamed to match the Google
Style guide, and some debug-only functions have been removed.

This commit still includes invalid files, but I decided to clean them
