Muchas grax to @guilledk for finding the first issue which kicked of this further scrutiny of the `tractor.Context` and `MsgStream` semantics test suite with a strange edge case where, - if the parent opened and immediately closed a stream while the remote child task started and continued (without terminating) to send msgs the parent's `open_context().__aexit__()` would **not block** on the child to complete! => this was seemingly due to a bug discovered inside the `.msg._ops.drain_to_final_msg()` stream handling case logic where we are NOT checking if `Context._stream` is non-`None`! As such this, - extends the `test_caller_closes_ctx_after_callee_opens_stream` (now renamed, see below) to include cases for all combinations of the child and parent sending before receiving on the stream as well as all placements of `Context.cancel()` in the parent before, around and after the stream open. - uses the new `expect_ctxc()` for expecting the taskc (`trio.Task` cancelled)` cases. - also extends the `test_callee_closes_ctx_after_stream_open` (also renamed) to include the case where the parent sends a msg before it receives. => this case has unveiled yet-another-bug where somehow the underlying `MsgStream._rx_chan: trio.ReceiveMemoryChannel` is allowing the child's `Return[None]` msg be consumed and NOT in a place where it is correctly set as `Context._result` resulting in the parent hanging forever inside `._ops.drain_to_final_msg()`.. Alongside, - start renaming using the new "remote-task-peer-side" semantics throughout the test module: "caller" -> "parent", "callee" -> "child". |
