# `Context.cancel()` was never called and thus the

# `._cancel_called: bool` was never set. Despite the
|
||||
# remote `.canceller` being set to `pikerd` (i.e. the
|
||||
# same `Actor.uid` of the raising service-mngr task) the
|
||||
# service-task's ctx itself was never marked as having
|
||||
# requested cancellation and thus still raises the ctxc
|
||||
# bc it was unaware of any such request.
|
||||
#
|
||||
# How to make grokin these cases easier tho?
|
||||
# ------------------------------------------
|
||||
# Because `Portal.cancel_actor()` was called it requests
|
||||
# "full-`Actor`-runtime-cancellation" of it's peer
|
||||
# process which IS NOT THE SAME as a single inter-actor
|
||||
# RPC task cancelling its local context with a remote
|
||||
# peer `Task` in that same peer process.
|
||||
#
|
||||
# ?TODO? It might be better if we do one (or all) of the
|
||||
# following:
|
||||
#
|
||||
# -[ ] at least set a special message for the
|
||||
# `ContextCancelled` when raised locally by the
|
||||
# unaware ctx task such that we check for the
|
||||
# `.canceller` being *our `Actor`* and in the case
|
||||
# where `Context._cancel_called == False` we specially
|
||||
# note that this is likely an "out-of-band"
|
||||
# runtime-cancel request triggered by some call to
|
||||
# `Portal.cancel_actor()`, possibly even reporting the
|
||||
# exact LOC of that caller by tracking it inside our
|
||||
# portal-type?
|

# maybe a,
