Took me longer then i wanted to figure out the source of a failed-response to a remote-cancellation (in this case in `modden` where a client was cancelling a workspace layer.. but disconnects before receiving the ack msg) that was triggering an IPC error when sending the error msg for the cancellation of a `Actor._cancel_task()`, but since this (non-rpc) `._invoke()` task was trying to send to a now disconnected canceller it was resulting in a `BrokenPipeError` (or similar) error. Now, we except for such IPC errors and only raise them when, 1. the transport `Channel` is for sure up (bc ow what's the point of trying to send an error on the thing that caused it..) 2. it's definitely for handling an RPC task Similarly if the entire main invoke `try:` excepts, - we only hide the call-stack frame from the debugger (with `__tracebackhide__: bool`) if it's an RPC task that has a connected channel since we always want to see the frame when debugging internal task or IPC failures. - we don't bother trying to send errors to the context caller (actor) when it's a non-RPC request since failures on actor-runtime-internal tasks shouldn't really ever be reported remotely, only maybe raised locally. Also some other tidying, - this properly corrects for the self-cancel case where an RPC context is cancelled due to a local (runtime) task calling a method like `Actor.cancel_soon()`. We now set our own `.uid` as the `ContextCancelled.canceller` value so that other-end tasks know that the cancellation was due to a self-cancellation by the actor itself. We still need to properly test for this though! - add a more detailed module doc-str. - more explicit imports for `trio` core types throughout. |
