time bytes are received or sent. The socket timeout is now the maximum total
duration of the method.

This change fixes a denial of service if the application is regulary
interrupted by a signal and the signal handler does not raise an exception.

Call internal_select() with a timeout of 0 second, not a timeout of -1 second
(blocking)!

each time data is sent successfuly. The socket timeout is now the maximum total
duration to send all data.

Use _PyTime_FromSeconds() to initialize the default socket timeout to -1
second, instead of -1 nanosecond which causes rounding issues in
internal_select().

orderable and non-orderable elements no longer depends on iteration order of
set or dict.

This changeset does two things: introduces a new RemoteDisconnected exception
(that subclasses ConnectionResetError and BadStatusLine) so that a remote
server disconnection can be detected by client code (and provides a better
error message for debugging purposes), and ensures that the client socket is
closed if a ConnectionError happens, so that the automatic re-connection code
can work if the application handles the error and continues on.

Tests are added that confirm that a connection is re-used or not re-used
as appropriate to the various combinations of protocol version and headers.

me.)

array_array_frombytes() is used in other functions, but it's signature was
changed. Closes issue #23866.

returns bool.  tkinter.BooleanVar now validates input values (accepted bool,
int, str, and Tcl_Obj).  tkinter.BooleanVar.get() now always returns bool.

PyArg_Parse instead of PyArg_ParseTuple if possible.

(empty) definition of the methoddef macro: it's only generated once, even
if Argument Clinic processes the same symbol multiple times, and it's emitted
at the end of all processing rather than immediately after the first use.
