363dbeae95 refactor(tvix): Centralize arbitrary definitions
To make it easier for future tests to use the arbitrary specialisations
we've defined for some nix types, centralize them all in a single
arbitrary.hh header file.

49024be056 feat(tvix): Thread a log sink through calls to buildDerivation
Similarly to how we did for buildPaths, add a std::ostream& log_sink
parameter to the build_derivation method on Store, and pass it std::cerr
when called at the top level by nix commands - most notably, the
build-remote hook binary, so that we get build logs when using tvix as a
remote builder.

c885bd0274 fix(tvix): globally reintroduce --quiet and --verbose flags.
The --quiet and -v/--verbose flags were removed during the glog
conversion in d0c44425e1, which has
previously broken programs like e.g. home-manager, which passes --quiet
to nix-build.

A nix-build-specific workaround was added in
24f9354d5b, which manipulates the
FLAGS_stderrthreshold global variable from glog. This commit moves the
--quiet logic back into the argument handling code in libmain, and adds
corresponding handling for -v/--verbose.

9bf6eb7f82 chore(tvix): avoid unnesscary rebuilds of protos and tvix
For the build of tvix we can safely ignore all the files in src/protos
as well as all the nix files in the root of the repository. By passing
the input sources through builtins.filterSource we can make a per-file
decision whether or not we want to copy it into the store (in other
words: if we consider it relevant for the build).

This enables much faster development on the actual build expression.

5a00e58904 chore(3p): Bump nixpkgs to nixos-unstable from 2020-11-21
Included fixes for random breakage:

* 3p/awscli: pick from the stable channel; it is broken on unstable
* 3p/googletest: bumped version & removed patches that nixpkgs applies
* 3p/lisp/cffi: bumped library version for SBCL compat
* 3p/nix: fix libsystemd attribute
* 3p/nix: reformatted (clang-format handling of ternaries changed)
* glittershark/home: Use home-manager from nixkpgs
* glittershark/kernel: bumped linux-ck patch hash
* glittershark/kernel: removed "patch patch"
* multi/whitby: Use home-manager from nixpkgs
* tazjin/frog: drop Sourcetrail (it doesn't build currently)

Note that in addition to these changes, some previous CLs updated the
versions of git and cgit which was necessary for this channel bump,
but which could not be done in the same commit due to the nature of
the subtree merges.

8d24a975f1 fix(tvix): Use copy constructor to add strings to protos
Passing a string directly to add_paths like this causes the proto class
to take ownership over the string, meaning when it is destructed it
will *explicitly* free the string. When the string's actual owner (the
derivation struct) then goes out of scope it'll get freed again, causing
a double-free. This fixes that to instead use the copy constructor to
assign to a pointer to a new path, and covers the whole to_proto method
with a rapidcheck test.

5dcf64c128 fix(tvix): Make working flag thread_local
Since the daemon is running in threads now rather than forking a process
per connection (thanks to grpc) this static flag to prevent accidentally
initializing a new worker during a build is getting stepped on by
multiple threads. This converts it to thread-local, and also adds an
actual message to the check so that if it hits in the future we know
what's going on.

8b7dcfaeba feat(tvix): Write even more build logs to client
Write *all* build logs (essentially everything that wasn't a DLOG), not
just the stdout of the builder, to the client-bound log_sink_ that's
threaded through build.cc. These logs are significantly more useful on
the client, both when debugging tvix itself and (more importantly) when
building things with it.

To make this all work, this commit also refactors the passing-around of
the log sink in build.cc slightly - the main reference is now owned by
the Worker class, which already stores pointers to itself on the Goals
it creates, so those Goals can then load the log sink from the Worker.
This change was originally made to allow for logging to the log_sink
from instance methods of the worker, but actually feels significantly
more natural than storing the sink on the goal anyway.

c5f3b12f04 feat(tvix): Support systemd socket activation
When the nix daemon starts up, first check (using sd_listen_fds) whether
we have been systemd socket-activated. If so, instead of passing the nix
daemon socket path to grpc, start a manual accept(2) loop, passing the
client file descriptors to grpc via AddInsecureChannelFromFd. There's an
open grpc issue at https://github.com/grpc/grpc/issues/19133 for
building support into grpc to do this automatically, but as of right now
this appears to be the only way to make this happen.

Making this happen, by the way, was a bit of a journey - at one point I
attempted to ServerBuilder's experimental AddExternalConnectionAcceptor
API, and that didn't work either - it appears that the final missing
piece to getting this working was explicitly fcntl(2)ing the client file
descriptors to set O_NONBLOCK before passing them into gRPC. With that
set, this all works inside of the test vm.

request size (4194304 bytes, it would appear), resulting in a
RESOURCE_EXHAUSTED error.

The initial chunk size, which is currently constant but should be made
dynamic at some point in the future, has been chosen based on the IPC
bandwidth delay product for tazjin's desktop, rounded up.

- .skip-subtrees on things that shouldn't be evaluated anyway
- Get rid of system/pkgs, and move the one thing in there that *wasn't*
  already in third_party (alsi) to third_party
- Drop notifymuch for now - it's not working, and I'll probably get it
  landed in nixpkgs before I manage to get it working
- Add __readTree = true to my systems so they get built.
- explicitly disable ci for xanthous, which is failing to build and had
  been omitted previously

fb0528c5da fix(tvix): Pass all args when auto-calling a function with an ellipsis
The command line options --arg and --argstr that are used by a bunch of
CLI commands to pass arguments to top-level functions in files go
through the same code-path as auto-calling top-level functions with
their default arguments - this, however, was only passing the arguments
that were *explicitly* mentioned in the formals of the function - in the
case of an as-pattern with an ellipsis (eg args @ { ... }) extra passed
arguments would get omitted. This fixes that to instead pass *all*
specified auto args in the case that our function has an ellipsis.

Previously, MixEvalArgs (a generic data type used to handle --arg,

the difference between --arg and --argstr by prepending a single
character (either 'E' or 'S') to the value of the arg. This is messy and
un-type-safe, so this commit refactors that to use a proper enum and a
std::pair, which allows us to add a switch and get totality checking.

883de9b8d7 feat(tvix): Add a no-op stream buffer for discarding build logs
In some cases we don't have anywhere for the build logs to go. Until
we understand those cases fully and can get rid of them, this null
sink implementation can be used.

Normally the Emacs attribute is versioned to make it clear which

to check that it is indeed 27.

1a48f39078 fix(tvix): Ensure prim_sort actually uses the right outlist
Previously the outlist would not be used, and it would sort god knows

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.

d44565d17e chore(3p): Pick Emacs & friends from the default channel
I had previously pinned Emacs to the (older) stable channel, because
of a heretofore undiagnosed issue in newer versions.

It turns out that the older Emacs is linking against X11-related
libraries, namely <unintelligible>, which cause even *weirder*
undiagnosed issues if paired with the rest of the recent packages.

This commit removes the exception for Emacs and just picks it from the
same channel as everything else.

72e61aa584 refactor(tvix): completely remove boehm gc
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.
