* 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
* Adjust API tests internal API
* Refactor API tests to take less time
- sqlite: tests 15s, overall time: 1m
- mysql: tests 15s, overall time: 59s
* Use retry func to survive in faulty places
* Use retry func while trying to ping SQL datastore
- implements retry func specifically for SQL datastore ping
- fmt fixes
- using sqlx.Db.PingContext instead of sqlx.Db.Ping
- propogate context to SQL datastore
* Simplify TestCanCauseTimeout retry loop
* Call retry with sane timeout
* Fix TestOversizedLog, use retry func
* Increase number of attempts
2 test cases are really faulty in CI, so they need a lot more time to finish.
* Increase TestCanCauseTimeout timeout
* Use retry at TestMultiLog to speed it up
* Use retry at TestCanWriteLogs to speed it up
* Use retry at TestGetCallsSuccess to speed it up
* Use retry at TestCanGetAsyncState to speed it up
* Use retry at TestListCallsSuccess to speed it up
* Remove sleep calls
* Remove dup test case
* Cleaup Calls API test
* Build API tests binary once
This patch lets CI to build API tests binary once and reuse that whenever it needs it
* Swap API tests checks
* Build API test binary by default
dirty fix for CircleCI
* Use retry func to determine if datastore is alive in tests
* go install should also reduce build time
* Fix rebase issues
