2020-11-19 r/1886 fix(tvix): Use copy constructor to add strings to protosGriffin Smith2-1/+29
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.

2020-11-19 r/1885 fix(tvix): Use mutable field for assigning proto fieldsGriffin Smith1-2/+2
This was accidentally using the proto arena API to assign the derivation field of a BuildDerivationRequest. We *thought* this was causing a double free, but even with this change that's still happening. That said, this change is probably still a good idea since it's using the proto API as intended.

2020-09-16 r/1795 fix(tvix): Convert INVALID_ARGUMENT to InvalidPathGriffin Smith1-2/+6
The code that calls queryPathInfoUncached explicitly catches the InvalidPath exception and translates it into a null result - but the RPC code was throwing a regular old Error for invalid paths. At some point we should get rid of all the exception-driven control flow in this whole thing, but in the meantime this gets us back to functional.

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.

2020-09-06 r/1767 feat(tvix): Write even more build logs to clientGriffin Smith1-89/+84
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 This change was originally made to allow for logging to the log_sink from instance methods of the worker, but actually feels significantly more natural than storing the sink on the goal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.

2020-09-01 r/1755 feat(tvix): Support systemd socket activationGriffin Smith2-14/+84
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.

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.

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.

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!

2020-08-14 r/1649 refactor(tvix): Make Store::buildPaths return a StatusGriffin Smith18-32/+137
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.

2020-08-14 r/1646 refactor(tvix): completely remove boehm gcKane York14-163/+51
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.

2020-08-09 r/1627 test(tvix): Cover scanForReferences in a testGriffin Smith6-5/+98
Aded a few test cases covering the scanForReferences function, which had been accidentally broken in 976a36c (which is now partially-reverted). As part of this, since the test needed to generate hashes for store paths, the logic in MakeStorePath to compress a sha256 hash down to 20 bytes and convert it to base32 has been extracted to a member function on the Hash class.
