* fn: lb and pure-runner with non-blocking agent *) Removed pure-runner capacity tracking code. This did not play well with internal agent resource tracker. *) In LB and runner gRPC comm, removed ACK. Now, upon TryCall, pure-runner quickly proceeds to call Submit. This is good since at this stage pure-runner already has all relevant data to initiate the call. *) Unless pure-runner emits a NACK, LB immediately streams http body to runners. *) For retriable requests added a CachedReader for http.Request Body. *) Idempotenty/retry is similar to previous code. After initial success in Engament, after attempting a TryCall, unless we receive NACK, we cannot retry that call. *) ch and naive places now wraps each TryExec with a cancellable context to clean up gRPC contexts quicker. * fn: err for simpler one-time read GetBody approach This allows for a more flexible approach since we let users to define GetBody() to allow repetitive http body read. In default LB case, LB executes a one-time io.ReadAll and sets of GetBody, which is detected by RunnerCall.RequestBody(). * fn: additional check for non-nil req.body * fn: attempt to override IO errors with ctx for TryExec * fn: system-tests log dest * fn: LB: EOF send handling * fn: logging for partial IO * fn: use buffer pool for IO storage in lb agent * fn: pure runner should use chunks for data msgs * fn: required config validations and pass APIErrors * fn: additional tests and gRPC proto simplification *) remove ACK/NACK messages as Finish message type works OK for this purpose. *) return resp in api tests for check for status code *) empty body json test in api tests for lb & pure-runner * fn: buffer adjustments *) setRequestBody result handling correction *) switch to bytes.Reader for read-only safety *) io.EOF can be returned for non-nil Body in request. * fn: clarify detection of 503 / Server Too Busy
