Jiri Daněk updated DISPATCH-2063:
---------------------------------
Description:
{code}
def dump(self):
print(self)
sys.stdout.flush()
@property
def __str__(self):
lines = [self.title]
for ts, msg in self.logs:
lines.append("%s %s" % (ts, msg))
res = str('\n'.join(lines))
return res
{code}
When dump() runs, Python's print() looks for a __str__ attribute on the
argument, it finds it and tries to call it (as a function). But here it is a
property which evaluates to a string, so this all fails with
{noformat}
