7deabb8c8d chore(3p): Bump channels to 2021-04-09
Fixes included:

* exposed gtest in the package set, required for protobuf
* pinned SBCL to version 2.0.8: The channel moved it to >2.1, and a
  bunch of warnings seemed to be killing our builds - we should
  investigate this later.
* removed kernel patches from //users/tazjin/frog: this machine is
  currently out of service anyways, not worth fixing while it's offline
* removed steam & lutris from frog (they're currently broken)
* removed Haskell overrides for hedgehog-classes & hgeometry-combinatorial
* use gRPC sources from upstream and inject Abseil via Nix instead
* fix for renamed grpc import in //third_party/nix
* use libfprint-tod from upstream nixpkgs in glittershark/yeren and
  delete glittershark/pkgs/fprintd entirely, since all of the patches used
  there are available and working from upstream now (and stopped working
  here after the bump)

e628862e97 chore(3p): Bump NixOS channels to 2021-02-18
Main motivation for this is to get the openldap update that fixes
10 CVEs: CVE-2020-36221 to including CVE-2020-36230. See also this
issue which lists them all: https://github.com/NixOS/nixpkgs/issues/113490

Someone should also redeploy whitby as soon as this lands in canon and
all build failures have been fixed.

Things done to resolve upstream breakages:

* grpc no longer takes abseil-cpp as an input, it has also been removed
  in the override.

* Upgrade glittershark's kernel to 5.11 since the linuxPackages_5_9
  attribute has been removed by upstream and the patch used by them is
  available for 5.11 as well.

* The fixed output hash for third_patry.apereo-cas changed for some reason.

* Remove the pin of haskellPackages.vector from the haskell overlay. It
  broke as the most recent version of vector in nixos-unstable no longer
  depends on semigroups. This effectively updates vector from 0.12.1.2
  to 0.12.2.0.

* Align two comments in tvix/libstore/worker-protocol.hh because the
  updated clang-format now demands that.

8709153973 fix(tvix/libexpr): backport fix for functionArgs failing on primops
Nix internally differentiates between lambdas and primops, but their
type in the nix expression language is the same (lambda). The
implementation of builtins.functionArgs only checks if the given
expression is of type tLambda and fails if the type is tPrimop or
tPrimopApp which are also functions. This most notably breaks
lib.generators.toPretty when called on a builtin making for example
yants fail if a primop is typechecked and an error message is
generated.

This fix generates an empty set for primops like for plain lambdas
and is based upstream commit b2748c6e99239ff6803ba0da76c362790c8be192.

Additionally we add to two tests:

* eval-okay-functionargs now includes a few test cases checking that
  builtins.functionArgs always returns an empty set for builtins and
  also works as expected for normal functions.
* eval-okay-types now also checks if builtins are functions.

Future work would be to make builtins.functionArgs work as users would
expect for builtins like builtins.fetchurl, builtins.fetchGit etc. which
take a set as an argument. These currently don't register as formal
arguments, but it would be an usability improvement at least if they
did.

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.

* 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.

c4136447b3 refactor(tvix): Remove default buildMode arguments from libstore
These were not used anyway, and *may* have been causing a weird series
of problems leading to things sometimes aborting. Or maybe it has
nothing to do with it - the only correlation we've found is from
disassembling the output of a core dump. Regardless, this feels
stylistically like a good idea.

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.

74a8c3d359 fix(tvix): Chunk the AddTextToStore request
Rather than sending the entire AddTextToStore request along in a single
message, send it in a stream of chunks using the same metadata-first
approach we've been using for the other store gRPC requests. This fixes
a bug where certain builds could send more data than the maximum gRPC
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.

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.

3bada1d41e refactor(tvix): Clean up MixEvalArgs internals
Previously, MixEvalArgs (a generic data type used to handle --arg,
--argstr, and -I arguments to `nix-build`, `nix eval`, etc.) was storing
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.
yay, types!

This is the clang-tidy lint 'google-explicit-constructor'.

There's a whole bunch of breakage that was introduced by this, and we
had to opt out a few types of this (esp. the string formatting crap).

In some cases minor other changes have been done to keep the code
working, instead of converting between types (e.g. an explicit
comparison operator implementation for nix::Pid).
