Description

The wait function in BlockingConnection will never timeout when the system clock is changed to past.

I attached a patch with a proposed solution.

 

File: python/proton/_utils.py

Function: def wait(self, condition, timeout=False, msg=None):

 

We never raise Timeout when system clock is changed to the past:

if deadline < time.time():
    txt = "Connection %s timed out" % self.url
    if msg:
    txt += ": " + msg
    raise Timeout(txt)
