    Description

      Starting in proton 0.28.0 and verified in 0.29.0b1 (pre-release) I can confirm following issue:

       

      from proton.utils import BlockingConnection
c = BlockingConnection(YOUR_ADDRESS)
c.close()

# ^^ FINE, all file descriptors closed properly

from proton.utils import BlockingConnection
c = BlockingConnection(YOUR_ADDRESS)
s = c.create_sender(YOUR_EXCHANGE)
s.close()
c.close()

# ^^ leaks the socket file descriptor - connection not closed properly (ls /proc/YOUR_PID/fd to verify)

       

      Version 0.27.0 is not affected by this issue.

       

      Having a quick look at the proton bindings, this very well might be bug in the qpid proton library itself, not the python bindings!
