Expose the global injector via gRPC

Separate build and init/restore steps via gRPC Most important changes: - `Simulation:step_unbounded` was renamed to `run`. - gRPC no longer saves the configuration within the simulation assets. - gRPC `InitAndRun` and `RestoreAndRun` were added to reduce the risk of real-time loss between the invocations of `Init/Restore` and `Run`. - gRPC now requires a `Build` request before any `Init/Restore(AndRun)` invocation.

Handle bench construction errors It is now possible to return a `boxed std::error::Error` from a bench construction function, with special-casing of gRPC errors reporting when the error is a `BenchError`. `InitError`was also renamed to `BenchError`.

Use Paths instead of Strings for source & sinks

Simplify the Sink API This commits also attempts to normalize the bench construcion style in examples and tests.

Massive rewrite of sink traits, endpoints and gRPC Sorry for this mammoth :-( This was intended as a sanitization of the bench endpoint API, but because it was tightly integrated with the sink-related traits (which had to be changed) and with the gRPC server (a lot of ttechnical debt that had to be finally paid), this ended up as a way too large commit. There are probably too many breaking changes to enumerate them all, but the main ones are probably: - The EventSinkReader traits has been rewritten fully to make it less weird and more similar to channel APIs. Instead of making blocking a configurable mode, the trait now exposes at the same time: (i) a non-blocking API, now in the form of try_read() instead of the Iterator super-trait (which was a bit of an abuse), (ii) a blocking API in the form of read(), (iii) an async API in the form of a Stream super-trait. - EventSlot has been temporarily removed until an implementation that conforms to the new API comes. - EventQueue has now been rewritten using an MPSC queue (the MPMC queue was actually a band aid but was dangerously closed of becoming part of the API). - Scheduler::halt is now a non-mutating method (the &mut self was probably an unintentional mistake?) - The gRPC API has been sanitized, with lots of new errors etc. This is totally non-compatible with prior versions. - The gRPC server architecture is now much saner and uses async mutexes and RW locks whenever it makes sense, with as well a better (and objective) rationale for the split into different services. - The endpoint API has been sanitized but is still in a state of flux, with currently a known issue with the event source registry that will be fixed when the new simulator API based on source/query IDs is merged.

OVarious gRPC improvements This patch in particular allows asynchronous gRPC access to the scheduler and to the monitoring functions.

Rename gRPC package as simulation.v1

Report an error if a message cannot be delivered

2024-11-18

Detect lost messages Messages sent to a mailbox that wasn't added to the simulation are now specifically detected. Earlier this would be wrongly reported as a deadlock.

Make the gRPC init more general Instead of producing a SimInit object, a bench is now expected to return a fully constructed simulation with its scheduler. This means that the client does not necessarily need to provide the starting time for the simulation. This start time may be hardcoded in the bench, or may be taken as a parameter for the bench configuration. This change make it possible for benches to do more, for instance to pre-schedule some events, or to do less, for instance by hardcoding the simulation time rather than accept an arbitrary simulation time.

2024-11-13

Report panics as errors + identify panicking model The build context is now passed as a mutable reference due to the need to mutate data when adding a model. Contains small unrelated cleanups and documentation improvements too.
