[New-bugs-announce] [issue4332] asyncore.file_dispatcher does not use dup()'ed fd

[Christian Becke]

New submission from Christian Becke <christianbecke at gmail.com>:

asyncore.file_dispatcher stores the file descriptor passed to
asyncore.file_dispatcher.__init__ into the map, not the dup()'ed one
created by asyncore.file_wrapper. Because of this, a "select.error (9,
'Bad file descriptor')" is raised in asyncore.loop() if the fd passed to
asyncore.file_dispatcher.__init__ is closed while the loop is running.
Attached patch fixes the issue.
