Event streaming hangs waiting for newline in Docker Desktop for Mac 2.2.0
bjd183 opened this issue · comments
As currently written, aiodocker expects docker events to be separated by newlines -- jsonstream.py calls response.content.readline(). For reference, docker-py reads chunked data and uses JSONDecoder.raw_decode() in case there are extra characters.
The downsides of this assumption (newline delimiters) are documented in this moby issue (20119).
In any case, Docker Desktop for Mac 2.2.0.0 causes aiodocker to hang waiting for a newline which never occurs even while multiple events are received.
Docker Desktop for Mac 2.1.0.5 works without issue and apparently separates events by newlines.
