Leak of active DBus connections #91
Description
- bleak version: master
- Python version: 3.7.3
- Operating System: Linux
- Bluez version: 5.50
Description
DBus connections are not cleaned up after usage. Multiple calls to discover() result eventually in following error:
Traceback (most recent call last):
File "discover.py", line 29, in <module>
loop.run_until_complete(run())
File "/usr/lib64/python3.7/asyncio/base_events.py", line 584, in run_until_complete
return future.result()
File "discover.py", line 22, in run
devices = await discover(timeout=1)
File "/home/joe/code/proglove/python/bleak/bleak/backends/bluezdbus/discovery.py", line 125, in discover
bus = await client.connect(reactor, "system").asFuture(loop)
txdbus.error.RemoteError: org.freedesktop.DBus.Error.LimitsExceeded: The maximum number of active connections for UID 1000 has been reached
For me this happens at the 246th call to discover()
