[New-bugs-announce] [issue18550] internal_setblocking() doesn't check return value of fcntl()

[Christian Heimes]

New submission from Christian Heimes:

http://hg.python.org/cpython/file/96d817f41c4c/Modules/socketmodule.c#l614

CID 715331 (#1 of 1): Unchecked return value from library (CHECKED_RETURN)
5. check_return: Calling function "fcntl(s->sock_fd, 4, delay_flag)" without checking return value. This library function may fail and return an error code.

It's rather tedious to fix the issue. No function checks the return value of internal_setblocking()...
