2020-08-20 r/1687 refactor(tvix): Remove some default values from virtual methodsVincent Ambo2-6/+18

2020-08-20 r/1686 feat(tvix): Implement std::streambuf for a build log -> gRPC sinkGriffin Smith1-0/+18
Introduces a class which implements std::streambuf by sending build log lines to the provided gRPC stream writer as individual messages. This can be used in the implementations of calls which trigger builds to forward logs back to the clients.

2020-08-20 r/1685 feat(tvix): Introduce build event streams in worker protocolVincent Ambo5-25/+92
Introduces a new `BuildEvent` proto type which is streamed in response to calls that trigger builds of derivations. This type can currently supply build statuses, log lines and information about builds starting. This is in preparation for threading build logs through the processes. Since we have nowhere to send the logs (yet), a null sink is used instead.

2020-08-14 r/1646 refactor(tvix): completely remove boehm gcKane York15-170/+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.
