2020-07-07 Library Evolution Minutes - D2203R0 Executors Review Report: Customization Points
Chair: Fabio Fracassi

Minute Taker: Ben Craig
Summary
We reviewed D2022R0 Sender/Receiver Review Report and D2203R0 Customization Point Report The Sender/Reciever report will be compiled into concrete questions to be polled at a later date.
POLL: We want to make the selection of Executor <-> Scheduler interoperation adapters more explicit and not provide implicit defaults (esp. setting terminate as the error channel when calling the execute cpo). Given the history of the consensus of R0443 this would need a paper.
| Strongly For | Weakly For | Neutral | Weakly Against | Strongly Against |
|---|---|---|---|---|
| 2 | 16 | 5 | 2 | 1 |
SA: The poll was taken without the primary dissenter

Outcome
This and the previous session were mostly informational, to identify open questions and make sure that we properly understand the programming model that we are integrating with Executors and Sender/Receivers.
One outcome is that we need lots of additional documentation and examples to make informed decisions, since the programming model (and the domain) is complex. Also to evaluate the proposed concepts we need to understand the algorithms in P1897 or P1898.
Most open issues we discovered seem to be at the seams and interactions between the two models Sender/Receiver and Executors, especially in the way that errors and cancelations are propagated between the two models.
