| Summary | Make native ports give nicer messages when probed or errors thrown |
|---|---|
| Description |
I noticed that there is a "native port" inside of the TCP scheme as an "actor". actor: make native! [[port!]] It does not respond in a nice way to probing. It says "Access error: invalid port object (invalid field values). It does the same thing for type inquiries. It would be nice if type? and probe did something that wasn't an error, but rather a nice friendly "internal!" kind of answer that didn't look like a bug. But even "Access error: internal port! objects are not to be touched or looked at" would be a start. Haven't looked into the internals to know what's feasible. |
| Example code |
>> foo: open tcp://10.20.03.04 >> probe foo/scheme/actor ** Access error: invalid port object (invalid field values) ** Where: actor ** Near: foo/scheme/actor >> type? foo/scheme/actor ** Access error: invalid port object (invalid field values) ** Where: actor ** Near: foo/scheme/actor |

The ACTOR is a native!, which is a function type. So what you are doing in your example code is calling this actor function. Compare the following:
>> foo: func [] [print "bar" 42] >> probe foo "bar" 42 == 42 >> type? foo == integer! This invokes FOO as part of gathering the arguments for PROBE or TYPE?. If you don't want to call FOO, you have to use a get-word: >> type? :foo == function! You can do the same for the native actors, with get-paths: >> type? :system/schemes/tcp/actor == native! |

To get informations about port, you have to QUERY it.
