Port rdeps --full, circular dependency

[Dave-Allured (Dave Allured)]

Here is a fun little puzzle for a cold Friday night. I can't tell if this is a base bug or a port bug. Current base 2.6.4, fresh build, fresh selfupdate, no ports installed. This makes an infinite loop with console spewage:

port rdeps --full py38-attrs

py38-attrs @20.3.0_0
py38-hypothesis @5.48.0_0
macOS 10.14.5 18F132
Xcode 10.2.1 10E1001

There is a circular dependency py38-attrs --> py38-hypothesis --> py38-attrs. However, I am confused because py38-hypothesis is only a test dependency of py38-attrs, not a build or library dependency. This does not loop unless --full is included.

So which one is this?

• Test dependency does not matter. It is still a circular dependency, and one of the ports has a bug.
• Test dependency is allowed to be circular. It is a bug in port rdeps.
• Don't care because nobody should ever run port rdeps --full.

Your thoughts?
