The new implementation of bind_port() will actually raise an exception if it is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed. This currently only applies to Windows. This option prevents any other sockets from binding to the host/port we've bound to, thus removing the possibility of the 'non-deterministic' behaviour, as Microsoft puts it, that occurs when a second SOCK_STREAM socket binds and accepts to a host/port that's already been bound by another socket. The optional preferred port parameter to bind_port() has been removed. Under no circumstances should tests be hard coding ports! test_support.find_unused_port() has also been introduced, which will pass a temporary socket object to bind_port() in order to obtain an unused port. The temporary socket object is then closed and deleted, and the port is returned. This method should only be used for obtaining an unused port in order to pass to an external program (i.e. the -accept [port] argument to openssl's s_server mode) or as a parameter to a server-oriented class that doesn't give you direct access to the underlying socket used. Finally, test_support.HOST has been introduced, which should be used for the host argument of any relevant socket calls (i.e. bind and connect). The following tests were updated to following the new conventions: test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib, test_poplib, test_ftplib, test_telnetlib, test_socketserver, test_asynchat and test_socket_ssl. It is now possible for multiple instances of the regression test suite to run in parallel without issue. ........ r62235 | gregory.p.smith | 2008-04-09 02:25:17 +0200 (Wed, 09 Apr 2008) | 3 lines Fix zlib crash from zlib.decompressobj().flush(val) when val was not positive.

:mod:`types` --- Names for built-in types
|
|
=========================================
|
|
|
|
.. module:: types
|
|
:synopsis: Names for built-in types.
|
|
|
|
|
|
This module defines names for some object types that are used by the standard
|
|
Python interpreter, but not for the types defined by various extension modules.
|
|
Also, it does not include some of the types that arise during processing such as
|
|
the ``listiterator`` type. New names exported by future versions of this module
|
|
will all end in ``Type``.
|
|
|
|
Typical use is for functions that do different things depending on their
|
|
argument types, like the following::
|
|
|
|
from types import IntType
|
|
def delete(mylist, item):
|
|
if type(item) is IntType:
|
|
del mylist[item]
|
|
else:
|
|
mylist.remove(item)
|
|
|
|
Starting in Python 2.2, built-in factory functions such as :func:`int` and
|
|
:func:`str` are also names for the corresponding types. This is now the
|
|
preferred way to access the type instead of using the :mod:`types` module.
|
|
Accordingly, the example above should be written as follows::
|
|
|
|
def delete(mylist, item):
|
|
if isinstance(item, int):
|
|
del mylist[item]
|
|
else:
|
|
mylist.remove(item)
|
|
|
|
Starting in Python 3.0 all types that are also available as builtins are no
|
|
longer exposed through the types module.
|
|
|
|
The module defines the following names:
|
|
|
|
.. data:: FunctionType
|
|
LambdaType
|
|
|
|
The type of user-defined functions and lambdas.
|
|
|
|
|
|
.. data:: GeneratorType
|
|
|
|
The type of :term:`generator`-iterator objects, produced by calling a
|
|
generator function.
|
|
|
|
|
|
.. data:: CodeType
|
|
|
|
.. index:: builtin: compile
|
|
|
|
The type for code objects such as returned by :func:`compile`.
|
|
|
|
|
|
.. data:: MethodType
|
|
|
|
The type of methods of user-defined class instances.
|
|
|
|
|
|
.. data:: BuiltinFunctionType
|
|
BuiltinMethodType
|
|
|
|
The type of built-in functions like :func:`len` or :func:`sys.exit`.
|
|
|
|
|
|
.. data:: ModuleType
|
|
|
|
The type of modules.
|
|
|
|
|
|
.. data:: TracebackType
|
|
|
|
The type of traceback objects such as found in ``sys.exc_info()[2]``.
|
|
|
|
|
|
.. data:: FrameType
|
|
|
|
The type of frame objects such as found in ``tb.tb_frame`` if ``tb`` is a
|
|
traceback object.
|
|
|
|
|
|
.. data:: GetSetDescriptorType
|
|
|
|
The type of objects defined in extension modules with ``PyGetSetDef``, such
|
|
as ``FrameType.f_locals`` or ``array.array.typecode``. This type is used as
|
|
descriptor for object attributes; it has the same purpose as the
|
|
:class:`property` type, but for classes defined in extension modules.
|
|
|
|
|
|
.. data:: MemberDescriptorType
|
|
|
|
The type of objects defined in extension modules with ``PyMemberDef``, such
|
|
as ``datetime.timedelta.days``. This type is used as descriptor for simple C
|
|
data members which use standard conversion functions; it has the same purpose
|
|
as the :class:`property` type, but for classes defined in extension modules.
|
|
In other implementations of Python, this type may be identical to
|
|
``GetSetDescriptorType``.
