This (finally) adds fully acknowledged remote cancellation messaging
|
||
|
|
support for both explicit ``Portal.cancel_actor()`` calls as well as
|
||
|
|
when there is a "runtime-wide" cancellations (eg. during KBI or general
|
||
|
|
actor nursery exception handling which causes a full actor
|
||
|
|
"crash"/termination).
|
||
|
|
|
||
|
|
You can think of this as the most ideal case in 2-generals where the
|
||
|
|
actor requesting the cancel of its child is able to always receive back
|
||
|
|
the ACK to that request. This leads to a more deterministic shutdown of
|
||
|
|
the child where the parent is able to wait for the child to fully
|
||
|
|
respond to the request. On a localhost setup, where the parent can
|
||
|
|
monitor the state of the child through process or other OS APIs instead
|
||
|
|
of solely through IPC messaging, the parent can know whether or not the
|
||
|
|
child decided to cancel with more certainty. In the case of separate
|
||
|
|
hosts, we still rely on a simple timeout approach until such a time
|
||
|
|
where we prefer to get "fancier".
