f7a85c5060 fix(3p/nix/expr): use traceable_allocator for btree_map
The prior use of gc_allocator meant that the btree nodes themselves were being collected. Additionally, have Attr (contains a Value) and Bindings explicitly inherit from gc, even though Bindings is always allocated under `new (GC)`.

Detected by running under GC_ENABLE_INCREMENTAL=1.

05e44c121d feat(3p/nix): Implement AddToStore proto handler
Implement the proto handler for AddToStore, which adds a nix path to the
store. This is implemented by adding a new (probably
soon-to-be-generalized) Source concretion that wraps a grpc ServerReader
for the stream of data we're receiving from the client - this is less
than ideal, as it's perpetuating the source/sink thing that's going on
and storing entire nars in memory, but is at the very worst an
incremental step towards a functioning nix that we can refactor in the
future.

e231493ff4 feat(3p/lisp): Add ironclad
Add ironclad, a common lisp library for cryptography. This is a huge
library with a lot of moving parts - probably most notable here is that
I've had to turn off compiling with `:ironclad-assembly`, as it was
causing an infinite loop in the compiler due to
https://github.com/sharplispers/ironclad/blob/master/src/opt/sbcl/cpu-features.lisp#L9-L10,
a mutually self-recursive function that looks like:

    (defun aes-ni-support-p ()
      (aes-ni-support-p))

Without knowing much about how sbcl handles native-compiled assembly, it
seems like this definition should actually be skipped entirely, due to
it being defined as a `defknown` in `fndb.lisp`:

    (defknown ironclad::aes-ni-support-p
      ()
      (boolean)
      (any)
      :overwrite-fndb-silently t)

But something about how we're compiling things was causing that not to
happen, and the infinite recursion caused the compiler to hang. This
should be fixed at some point, but given I only need this library as a
transitive dependency down a level I'm not going to attempt to do so now.

2fcf2d0d20 refactor(3p/nix): Remove custom base64 implementation
Replace the custom, rather questionable base64 implementation with
absl::Base64{Une,E}scape. To make sure that the custom implementation
was doing the same thing I've also added a test covering
nix::Hash::to_string, which was one function that used it - the test
passed prior to the replacement, and continued to pass afterwards.

The previous base64Decode function threw an exception on failure - to
avoid going too far down the rabbit hole I've replicated that
functionality at all call sites, but this should be replaced with more
sensible error handling such as StatusOr eventually.

Also, before this change:

    ❯ nix eval -f . users.tazjin.emacs.outPath
    "/nix/store/g6ri2q8nra96ix20bcsc734r1yyaylb1-tazjins-emacs"

bd77090703 fix(3p/nix): do not call vfork
The use of vfork() in Nix is entirely illegal. Quote:

If the process created by vfork() returns from the function in which vfork() was
called, or calls any other function before successfully calling _exit() or
one of the exec*() family of functions, the behavior is undefined.

-- Linux man-pages, release 5.05

Add a TODO to use the higher-performance variants of clone() on Linux when it
is available.

be98295dc2 feat(3p/cgit): add "this commit" option to switch form
Branches are grouped into their own section to make the "this commit"
option visually distinct.

Adding this option will result in two options being marked as selected
if a branch has the same name as a commit oid.  But that would cause
all sorts of other problems anyway (attempting to switch to the branch
would actually give you the commit, etc.), so let's not worry about
that.

A "permalink" link on the blob view next to the "plain" link would
probably be more discoverable, but that would only work for the blob
view.  The switch UI is visible everywhere.

This patch is in use already at <https://git.qyliss.net/> and
<https://spectrum-os.org/git/>.

which I had missed on the first pass, including the actual proto

deployed yet.

A couple things to note

- I implemented a couple constructors for nix classes that initialize
  themselves based on their proto variants, which felt nice and didn't
  end up causing any issues.
- I've made the conversions between the enum types in nix and in proto
  explicit via switch statements rather than using a static_cast, out of
  an abundance of caution that the error would get mismatched in the
  future and we'd convert the wrong thing to the wrong thing - this is
  verbose, but exceptionally future proof.

cbea59c5f6 chore(3p/nix): don't rebuild nix-proto-srcs as much
Interpolating a path into a string will copy the referenced path into
the Nix store, so this got a dependency on all of src.  By first
constructing a path to the src/proto directory using the + operator,
and then interpolating it, we limit what is copied to the store, and
therefore what code triggers a nix-proto-srcs rebuild.

cdc1a0bb6e refactor(3p/nix/libexpr): Back Nix lists with std::vector
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.

56614c75e4 refactor(3p/nix/libexpr): Store nix::Env values in a std::vector
This has several advantages:

* we can ensure that the vector is traced by the GC
* we don't need to unsafely allocate memory to make an Env

Note that there was previously a check about the size of the
environment, but it's unclear why this was the case (git history
yielded nothing interesting) and it seems to have no effect.

f4f72bcf21 test(3p/nix): Set up scaffolding & fix up tests for value-to-{json|xml}
Configures the CMake build to load & run the GoogleTest tests.

I (grfn) also updated this to get the tests running as part of the nix
derivation, which required defining our own manual configurePhase and
installCheckPhase, rather than depending on the one provided by stdenv.
Not doing this would cause cmake to attempt to *run* the tests as part
of the buildPhase, which wouldn't work because the dynamic libraries
hadn't been put into a place where the test executables knew where to
find them. We're not sure *why* this fixes it, and for some reason
fixing this also breaks the automatic behavior of nixpkgs of passing
-j$NIX_BUILD_CORES -l$NIX_BUILD_CORES to make, but that's eaasy enough
to fix manually in a preBuild

Replaces the previous uses of the (ordered!) std::map and std::set

After some careful reading it seems that there is actually no

perform slightly better.

Overall this is not fixing a bottleneck, just a driveby thing.

d579ceb783 refactor(3p/nix/libexpr): Extract parser header out of Yacc file
First step (of many?) towards extracting all the inline code from the
Yacc file and keeping it somewhere more accessible instead.

Note that none of this code has previously been touched by a linter or
formatter, pretty much ever, so as it is extracted it also undergoes
similar changes to the whole codebase after the initial fork.

cb3d967508 refactor(3p/nix/libexpr): Use range insertion to merge nix::Bindings
Instead of manually iterating over the two bindings to be combined,
this adds a new static method on the Bindings class which merges two
attribute sets by calling the range insertion operator over them.

In some anecdotal tests, this can lead to a ~10% speed bump -
depending on the specific operation.

1390827b9e refactor(3p/nix): Revert VectorBindings implementation
This reverts parts of the CLs splitting the backing implementation for
Bindings and moves back to only the BTreeMap-backed implementation.

Our evaluation has indicated that the Vector-backed implementation
does not match the performance of the plain array used upstream, and
in my view the complexity introduced by it is not worth the relatively
small (single-digit percentage) performance increase with a
pivot-point close to the number of attributes yielded by
stdenv.mkDerivation.

Going forward we will trial implementations of attribute sets backed
by HAMTs, and investigate other mechanisms of speeding up the language.

Some changes from the previous CLs are retained, for example the
removal of insert_or_assign and the passing of capacity.

To aid in making the decision of where to (currently just statically)
use a vector or btree as the backing implementation, add an extra
constructor argument to Bindings::NewGC for a capacity, and use
a (currently hardcoded at 32, for no good reason other than it felt like
a reasonable number) pivot to switch between our possible backing
implementations. Then, update all the call sites where it feels
reasonable that we know the capacity statically to *pass* that capacity
to the constructor.

98148e6711 refactor(3p/nix): Abstract away concrete bindings impl
To pave the way for the thing we want to do eventually which is use a
linear-time array for bindings (aka attribute sets) that are statically
known to be small enough to get a performance benefit from doing so,
make the Bindings class abstract, and define a BTreeBindings class that
inherits from it and is (currently always) returned from the static
initializer. The idea is that we'll have an ArrayBindings class as well
later that we can dispatch to conditionally based on an optional
"capacity" parameter or something like that.

There was some difficulty here in getting the iterator to work - the
approach we settled on ended up making a concrete BindingsIterator class
which will wrap a std::variant of either a btree iterator or something
else later, but right now just wraps a btree iterator.

f3165f48aa refactor(3p/nix/libexpr): Make nix::AttrName a std::variant
nix:AttrName was one of the few classes that relied on the default
constructor of nix::Symbol (which I am trying to remove in a separate
change).

The class essentially represents the name of an attribute in a set,
which is either just a string expression or a dynamically evaluated
expression (e.g. string interpolation).

Previously it would be constructed by only setting one of the fields
and defaulting the other, now it is an explicit std::variant.

Note that there are several code paths where not all eventualities are
handled and this code is bug-for-bug compatible with those, except
that unknown conditions (which should never work) are now throwing
instead of silently doing ... something.

The language tests pass with this change, and the depot derivations
that I tested with evaluated successfully.
