New submission from Roy Smith <[email protected]>:
While investigating issue7322, I wrote a test case to demonstrate the issue. I
made a mistake and called settimeout() on the wrong socket, but the result
appears to demonstrate a different bug. When I run the attached
test-issue7322.py on my OSX-10.6.5 machine, using...
Python 3.2a4+ (py3k:86538, Nov 19 2010, 20:52:31)
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin
I get the output below. The bug is that readline() is returning, even though I
never wrote a newline on the other side of the connection. If I comment out
the settimeout() call, it hangs in the readline() call, as expected.
While I admit it makes no sense to call settimeout() on the listening socket,
doing so certainly should not cause this behavior.
Note: I also tried this on Ubuntu linux (with python built from the same 3.2a4+
sources). I cannot reproduce the problem there.
