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.

This was accidentally using the proto arena API to assign the derivation field of a BuildDerivationRequest.

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.

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 This change was originally made to allow for logging to the log_sink from instance methods of the worker, but actually feels significantly more natural than storing the sink on the goal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.

2020-08-17 r/1658 refactor(tvix): always pass Bindings by ptr, use shared/unique_ptrKane York22-103/+125
Value now carries a shared_ptr<Bindings>, and all Bindings constructors return a unique_ptr<Bindings>. The test that wanted to compare two Bindings by putting them into Values has been modified to use the new Equal() method on Bindings (extracted from EvalState).

2020-08-15 r/1655 fix(tvix): Ensure prim_sort actually uses the right outlistVincent Ambo2-4/+5
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.

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.
