| In Python, instance intialization happens in the ``__init__`` method. | ||
| Generally speaking, you should keep as little logic as possible in it, and you should think about what the class needs and not how it is gonna be instantiated. |

| Generally speaking, the moment you think that you need a finer control over how your class is instantiated than what ``attrs`` offers, it's usually best to use a classmethod factory or to apply the `builder pattern <https://en.wikipedia.org/wiki/Builder_pattern>`_. |

I believe I’ve addressed everything. I’ve also added a news fragment to point people to our new chapters. |

treatment of private attributes is obscure, nearly undocumented, perhaps not ideal in all cases

185: Scheduled weekly dependency update for week 18 r=mithrandi a=pyup-bot ### Update [attrs](https://pypi.org/project/attrs) from **17.4.0** to **18.1.0**. <details> <summary>Changelog</summary> ### 18.1.0 ``` ------------------- Changes ^^^^^^^ - ``x=X(); x.cycle = x; repr(x)`` will no longer raise a ``RecursionError``, and will instead show as ``X(x=...)``. `95 <https://github.com/python-attrs/attrs/issues/95>`_ - ``attr.ib(factory=f)`` is now syntactic sugar for the common case of ``attr.ib(default=attr.Factory(f))``. `178 <https://github.com/python-attrs/attrs/issues/178>`_, `356 <https://github.com/python-attrs/attrs/issues/356>`_ - Added ``attr.field_dict()`` to return an ordered dictionary of ``attrs`` attributes for a class, whose keys are the attribute names. `290 <https://github.com/python-attrs/attrs/issues/290>`_, `349 <https://github.com/python-attrs/attrs/issues/349>`_ - The order of attributes that are passed into ``attr.make_class()`` or the ``these`` argument of ``attr.s()`` is now retained if the dictionary is ordered (i.e. ``dict`` on Python 3.6 and later, ``collections.OrderedDict`` otherwise). Before, the order was always determined by the order in which the attributes have been defined which may not be desirable when creating classes programatically. `300 <https://github.com/python-attrs/attrs/issues/300>`_, `339 <https://github.com/python-attrs/attrs/issues/339>`_, `343 <https://github.com/python-attrs/attrs/issues/343>`_ - In slotted classes, ``__getstate__`` and ``__setstate__`` now ignore the ``__weakref__`` attribute. `311 <https://github.com/python-attrs/attrs/issues/311>`_, `326 <https://github.com/python-attrs/attrs/issues/326>`_ - Setting the cell type is now completely best effort. This fixes ``attrs`` on Jython. We cannot make any guarantees regarding Jython though, because our test suite cannot run due to dependency incompatabilities. `321 <https://github.com/python-attrs/attrs/issues/321>`_, `334 <https://github.com/python-attrs/attrs/issues/334>`_ - If ``attr.s`` is passed a *these* argument, it will not attempt to remove attributes with the same name from the class body anymore. `322 <https://github.com/python-attrs/attrs/issues/322>`_, `323 <https://github.com/python-attrs/attrs/issues/323>`_ - The hash of ``attr.NOTHING`` is now vegan and faster on 32bit Python builds. `331 <https://github.com/python-attrs/attrs/issues/331>`_, `332 <https://github.com/python-attrs/attrs/issues/332>`_ - The overhead of instantiating frozen dict classes is virtually eliminated. `336 <https://github.com/python-attrs/attrs/issues/336>`_ - Generated ``__init__`` methods now have an ``__annotations__`` attribute derived from the types of the fields. `363 <https://github.com/python-attrs/attrs/issues/363>`_ - We have restructured the documentation a bit to account for ``attrs``' growth in scope. Instead of putting everything into the `examples <http://www.attrs.org/en/stable/examples.html>`_ page, we have started to extract narrative chapters. So far, we've added chapters on `initialization <http://www.attrs.org/en/stable/init.html>`_ and `hashing <http://www.attrs.org/en/stable/hashing.html>`_. Expect more to come! `369 <https://github.com/python-attrs/attrs/issues/369>`_, `370 <https://github.com/python-attrs/attrs/issues/370>`_ ---- ``` </details> <details> <summary>Links</summary> - PyPI: https://pypi.org/project/attrs - Changelog: https://pyup.io/changelogs/attrs/ - Homepage: http://www.attrs.org/ </details> ### Update [cffi](https://pypi.org/project/cffi) from **1.11.2** to **1.11.5**. <details> <summary>Changelog</summary> ### 1.11.5 ``` ======= * `Issue 357`_: fix ``ffi.emit_python_code()`` which generated a buggy Python file if you are using a ``struct`` with an anonymous ``union`` field or vice-versa. * Windows: ``ffi.dlopen()`` should now handle unicode filenames. * ABI mode: implemented ``ffi.dlclose()`` for the in-line case (it used to be present only in the out-of-line case). * Fixed a corner case for ``setup.py install --record=xx --root=yy`` with an out-of-line ABI module. Also fixed `Issue 345`_. * More hacks on Windows for running CFFI's own ``setup.py``. * `Issue 358`_: in embedding, to protect against (the rare case of) Python initialization from several threads in parallel, we have to use a spin-lock. On CPython 3 it is worse because it might spin-lock for a long time (execution of ``Py_InitializeEx()``). Sadly, recent changes to CPython make that solution needed on CPython 2 too. * CPython 3 on Windows: we no longer compile with ``Py_LIMITED_API`` by default because such modules cannot be used with virtualenv. `Issue 350`_ mentions a workaround if you still want that and are not concerned about virtualenv: pass a ``define_macros=[("Py_LIMITED_API", None)]`` to the ``ffibuilder.set_source()`` call. .. _`Issue 345`: https://bitbucket.org/cffi/cffi/issues/345/ .. _`Issue 350`: https://bitbucket.org/cffi/cffi/issues/350/ .. _`Issue 358`: https://bitbucket.org/cffi/cffi/issues/358/ .. _`Issue 357`: https://bitbucket.org/cffi/cffi/issues/357/ ``` ### 1.11.4 ``` ======= * Windows: reverted linking with ``python3.dll``, because virtualenv does not make this DLL available to virtual environments for now. See `Issue 355`_. On Windows only, the C extension modules created by cffi follow for now the standard naming scheme ``foo.cp36-win32.pyd``, to make it clear that they are regular CPython modules depending on ``python36.dll``. .. _`Issue 355`: https://bitbucket.org/cffi/cffi/issues/355/ ``` ### 1.11.3 ``` ======= * Fix on CPython 3.x: reading the attributes ``__loader__`` or ``__spec__`` from the cffi-generated lib modules gave a buggy SystemError. (These attributes are always None, and provided only to help compatibility with tools that expect them in all modules.) * More Windows fixes: workaround for MSVC not supporting large literal strings in C code (from ``ffi.embedding_init_code(large_string)``); and an issue with ``Py_LIMITED_API`` linking with ``python35.dll/python36.dll`` instead of ``python3.dll``. * Small documentation improvements. ``` </details> <details> <summary>Links</summary> - PyPI: https://pypi.org/project/cffi - Changelog: https://pyup.io/changelogs/cffi/ - Docs: http://cffi.readthedocs.org </details> ### Update [cryptography](https://pypi.org/project/cryptography) from **2.1.4** to **2.2.2**. <details> <summary>Changelog</summary> ### 2.2.1 ``` ~~~~~~~~~~~~~~~~~~ * Reverted a change to ``GeneralNames`` which prohibited having zero elements, due to breakages. * Fixed a bug in :func:`~cryptography.hazmat.primitives.keywrap.aes_key_unwrap_with_padding` that caused it to raise ``InvalidUnwrap`` when key length modulo 8 was zero. .. _v2-2: ``` ### 2.2 ``` ~~~~~~~~~~~~~~~~ * **BACKWARDS INCOMPATIBLE:** Support for Python 2.6 has been dropped. * Resolved a bug in ``HKDF`` that incorrectly constrained output size. * Added :class:`~cryptography.hazmat.primitives.asymmetric.ec.BrainpoolP256R1`, :class:`~cryptography.hazmat.primitives.asymmetric.ec.BrainpoolP384R1`, and :class:`~cryptography.hazmat.primitives.asymmetric.ec.BrainpoolP512R1` to support inter-operating with systems like German smart meters. * Added token rotation support to :doc:`Fernet </fernet>` with :meth:`~cryptography.fernet.MultiFernet.rotate`. * Fixed a memory leak in :func:`~cryptography.hazmat.primitives.asymmetric.ec.derive_private_key`. * Added support for AES key wrapping with padding via :func:`~cryptography.hazmat.primitives.keywrap.aes_key_wrap_with_padding` and :func:`~cryptography.hazmat.primitives.keywrap.aes_key_unwrap_with_padding` . * Allow loading DSA keys with 224 bit ``q``. .. _v2-1-4: ``` </details> <details> <summary>Links</summary> - PyPI: https://pypi.org/project/cryptography - Changelog: https://pyup.io/changelogs/cryptography/ - Repo: https://github.com/pyca/cryptography </details> ### Update [hyperlink](https://pypi.org/project/hyperlink) from **17.3.1** to **18.0.0**. *The bot wasn't able to find a changelog for this release.

If no option is selected, the value of the first option is returned (instead of None). If multiple options are selected, the value of the last one is returned (instead of that of the first one). If no options are present (not standard-compliant) ``SelectElement.value`` still returns ``None``. * GH261: The ``HTMLParser()`` now supports the ``huge_tree`` option. Patch by stranac.

Reported by tebriel (gh issue 406), fixed by mariocj89 (gh pr 494) - Added python_requires to setup.py so that pip will distribute the right version of dateutil. Fixed by jakec-github (gh issue 537, pr 552) - Added the utils submodule, for miscellaneous utilities. - Added within_delta function to utils - added by justanr (gh issue 432, gh pr 437) - Added today function to utils (gh pr 474) - Added default_tzinfo function to utils (gh pr 475), solving an issue reported by nealmcb (gh issue 94) - Added dedicated ISO 8601 parsing function isoparse (gh issue 424). Initial implementation by pganssle in gh pr 489 and 622, with a pre-release fix by kirit93 (gh issue 546, gh pr 573). - Moved parser module into parser/_parser.py and officially deprecated the use of several private functions and classes from that module. (gh pr 501, 515) - Tweaked parser error message to include rejected string format, added by pbiering (gh pr 300) - Add support for parsing bytesarray, reported by uckelman (gh issue 417) and fixed by uckelman and pganssle (gh pr 514) - Started raising a warning when the parser finds a timezone string that it cannot construct a tzinfo instance for (rather than succeeding with no indication of an error). Reported and fixed by jbrockmendel (gh pr 540) - Dropped the use of assert in the parser. Fixed by jbrockmendel (gh pr 502) - Fixed to assertion logic in parser to support dates like '2015-15-May', reported and fixed by jbrockmendel (gh pr 409) - Fixed IndexError in parser on dates with trailing colons, reported and fixed by jbrockmendel (gh pr 420) - Fixed bug where hours were not validated, leading to improper parse.

Reported by asishm (gh issue 360), fixed by jbrockmendel (gh pr 483) - Fixed problem parsing certain unambiguous strings when year <99 (gh pr 510). Reported by alexwlchan (gh issue 293). - Fixed issue with parsing an unambiguous string representation of an ambiguous datetime such that if possible the correct value for fold is set. Fixes issue reported by JordonPhillips and pganssle (gh issue 318, 320, gh pr 517) - Fixed issue with improper rounding of fractional components.

(gh pr 628) - Changed the behavior of tz.tzutc to return a singleton (gh pr 497, 504) - Changed the behavior of tz.tzoffset to return the same object when passed the same inputs, with a corresponding performance improvement (gh pr 504) - Changed the behavior of tz.tzstr to return the same object when passed the same inputs. (gh pr 628) - Added .instance alternate constructors for tz.tzoffset and tz.tzstr, to allow the construction of a new instance if desired. (gh pr 628) - Added the tz.gettz.nocache function to allow explicit retrieval of a new instance of the relevant tzinfo. (gh pr 628) - Expand definition of tz.tzlocal equality so that the local zone is allow equality with tzoffset and tzutc. (gh pr 598) - Deprecated the idiosyncratic tzstr format mentioned in several examples but evidently designed exclusively for dateutil, and very likely not used by any current users. (gh issue 595, gh pr 606) - Added the tz.resolve_imaginary function, which generates a real date from an imaginary one, if necessary. Implemented by Cheukting (gh issue 339, gh pr 607) - Fixed issue where the tz.tzstr constructor would erroneously succeed if passed an invalid value for tzstr. Fixed by pablogsal (gh issue 259, gh pr 581) - Fixed issue with tz.gettz for TZ variables that start with a colon. Reported and fixed by lapointexavier (gh pr 601) - Added a lock to tz.tzical's cache. Reported and fixed by Unrud (gh pr 430) - Fixed an issue with fold support on certain Python 3 implementations that used the pre-3.6 pure Python implementation of datetime.replace, most notably pypy3 (gh pr 446). - Added support for VALUE=DATE-TIME for DTSTART in rrulestr. Reported by potuz (gh issue 401) and fixed by Unrud (gh pr 429) - Started enforcing that within VTIMEZONE, the VALUE parameter can only be omitted or DATE-TIME, per RFC 5545. Reported by Unrud (gh pr 439) - Added support for TZID parameter for DTSTART in rrulestr.

[Got an idea?](https://github.com/pyupio/changelogs/issues/new)* <details> <summary>Links</summary> - PyPI: https://pypi.org/project/pytz - Homepage: http://pythonhosted.org/pytz - Docs: https://pythonhosted.org/pytz/ </details> ### Update [twisted[tls,conch]](https://pypi.org/project/twisted) from **17.9.0** to **18.4.0**. <details> <summary>Changelog</summary> ### 18.4.0 ``` =========================== Features -------- - The --port/--https arguments to web plugin are now deprecated, in favor of --listen. The --listen argument can be given multiple times to listen on multiple ports. (6670) - Twisted now requires zope.interface 4.4.2 or higher across all platforms and Python versions. (8149) - The osx_platform setuptools extra has been renamed to macos_platform, with the former name being a compatibility alias. (8848) - Zsh completions are now provided for the twist command. (9338) - twisted.internet.endpoints.HostnameEndpoint now has a __repr__ method which includes the host and port to which the endpoint connects. (9341) Bugfixes -------- - twistd now uses the UID's default GID to initialize groups when --uid is given but --gid is not. This prevents an unhandled TypeError from being raised when os.initgroups() is called. (4442) - twisted.protocols.basic.LineReceiver checks received lines' lengths against its MAX_LENGTH only after receiving a complete delimiter. A line ending in a multi-byte delimiter like '\r\n' might be split by the network, with the first part arriving before the rest; previously, LineReceiver erroneously disconnected if the first part, e.g. 'zzzz....\r' exceeded MAX_LENGTH. LineReceiver now checks received data against MAX_LENGTH plus the delimiter's length, allowing short reads to complete a line. (6556) - twisted.protocols.basic.LineOnlyReceiver disconnects the transport after receiving a line that exceeds MAX_LENGTH, like LineReceiver. (6557) - twisted.web.http.Request.getClientIP now returns the host part of the client's address when connected over IPv6. (7704) - twisted.application.service.IService is now documented as requiring the 'running', 'name' and 'parent' attributes (the documentation previously implied they were required, but was unclear). (7922) - twisted.web.wsgi.WSGIResource no longer raises an exception when a client connects over IPv6. (8241) - When using TLS enable automatic ECDH curve selection on OpenSSL 1.0.2+ instead of only supporting P-256 (9210) - twisted.trial._dist.worker and twisted.trial._dist.workertrial consistently pass bytes, not unicode to AMP. This fixes "trial -j" on Python 3. (9264) - twisted.trial.runner now uses the 'importlib' module instead of the 'imp' module on Python 3+. This eliminates DeprecationWarnings caused by importing 'imp' on Python 3. (9275) - twisted.web.client.HTTP11ClientProtocol now closes the connection when the server is sending a header line which is longer than he line limit of twisted.protocols.basic.LineReceiver.MAX_LENGTH. (9295) - twisted.python.failure now handles long stacktraces better; in particular it will log tracebacks for stack overflow errors. (9301) - The "--_shell-completion" argument to twistd now works on Python 3. (9303) - twisted.python.failure.Failure now raises the wrapped exception in Python3, and self (Failure) n Python2 when trap() is called without a matching exception (9307) - Writing large amounts of data no longer implies repeated, expensive copying under Python 3. Python 3's write speeds are now as fast as Python 2's. (9324) - twisted.protocols.postfix now properly encodes errors which are unicode strings to bytes. (9335) - twisted.protocols.policies.ProtocolWrapper and twisted.protocols.tls.TLSMemoryBIOProtocol no longer create circular references that keep protocol instances in memory after connection is closed. (9374) - twisted.conch.ssh.transport.SSHTransportBase no longer strips trailing spaces from the SSH version string of the connected peer. (9377) - `trial -j` no longer crashes on Python 2 on test failure messages containing non-ASCII bytes. (9378) - RSA keys replaced with 2048bit ones in twisted.conch.test.keydata in order to be compatible with OpenSSH 7.6. (9388) - AsyncioSelectorReactor uses the global policy's event loop. asyncio libraries that retrieve the running event loop with get_event_loop() will now receive the one used by AsyncioSelectorReactor. (9390) Improved Documentation ---------------------- - public attributes of `twisted.logger.Logger` are now documented as attributes. (8157) - List indentation formatting errors have been corrected throughout the documentation. (9256) Deprecations and Removals ------------------------- - twisted.protocols.basic.LineOnlyReceiver.lineLengthExceeded no longer returns twisted.internet.error.ConnectionLost. It instead directly disconnects the transport and returns None. (6557) - twisted.python.win32.getProgramsMenuPath and twisted.python.win32.getProgramFilesPath were deprecated in Twisted 15.3.0 and have now been removed. (9312) - Python 3.3 is no longer supported. (9352) Misc ---- - 7033, 8887, 9204, 9289, 9291, 9292, 9293, 9302, 9336, 9355, 9356, 9364, 9375, 9381, 9382, 9389, 9391, 9393, 9394, 9396 Conch ----- Bugfixes ~~~~~~~~ - twisted.plugins.cred_unix now properly converts a username and password from bytes to str on Python 3. In addition, passwords which are encrypted with SHA512 and SH256 are properly verified. This fixes running a conch server with: "twistd -n conch -d /etc/ssh/ --auth=unix". (9130) - In twisted.conch.scripts.conch, on Python 3 do not write bytes directly to sys.stderr. On Python 3, this fixes remote SSH execution of a command which fails. (9344) Deprecations and Removals ~~~~~~~~~~~~~~~~~~~~~~~~~ - twisted.conch.ssh.filetransfer.FileTransferClient.wasAFile attribute has been removed as it serves no purpose. (9362) - Removed deprecated support for PyCrypto key objects in conch (9368) Web --- Features ~~~~~~~~ - The new twisted.iweb.IRequest.getClientAddress returns the IAddress provider representing the client's address. Callers should check the type of the returned value before using it. (7707) - Eliminate use of twisted.python.log in twisted.web modules. (9280) Bugfixes ~~~~~~~~ - Scripts ending with .rpy, .epy, and .cgi now execute properly in Twisted Web on Python 3. (9271) - twisted.web.http.Request and twisted.web.server.Request are once again hashable on Python 2, fixing a regression introduced in Twisted 17.5.0. (9314) Improved Documentation ~~~~~~~~~~~~~~~~~~~~~~ - Correct reactor docstrings for twisted.web.client.Agent and twisted.web.client._StandardEndpointFactory to communicate interface requirements since 17.1. (9274) - The examples for the "Twisted Web in 60 Seconds" tutorial have been fixed to work on Python 3. (9285) Deprecations and Removals ~~~~~~~~~~~~~~~~~~~~~~~~~ - twisted.iweb.IRequest.getClientIP is deprecated. Use twisted.iweb.IRequest.getClientAddress instead (see 7707). (7705) - twisted.web.iweb.IRequest.getClient and its implementations (deprecated in 2552) have been removed. (9395) Mail ---- Bugfixes ~~~~~~~~ - twistd.mail.scripts.mailmail has been ported to Python 3. (8487) - twisted.mail.bounce now works on Python 3. (9260) - twisted.mail.pop3 and twisted.mail.pop3client now work on Python 3. (9269) - SMTP authentication in twisted.mail.smtp now works better on Python 3, due to improved improved bytes vs unicode handling. (9299) Misc ~~~~ - 9310 Words ----- No significant changes.

133: Scheduled weekly dependency update for week 18 r=mithrandi a=pyup-bot ### Update [attrs](https://pypi.org/project/attrs) from **17.4.0** to **18.1.0**. <details> <summary>Changelog</summary> ### 18.1.0 ``` ------------------- Changes ^^^^^^^ - ``x=X(); x.cycle = x; repr(x)`` will no longer raise a ``RecursionError``, and will instead show as ``X(x=...)``. `95 <https://github.com/python-attrs/attrs/issues/95>`_ - ``attr.ib(factory=f)`` is now syntactic sugar for the common case of ``attr.ib(default=attr.Factory(f))``. `178 <https://github.com/python-attrs/attrs/issues/178>`_, `356 <https://github.com/python-attrs/attrs/issues/356>`_ - Added ``attr.field_dict()`` to return an ordered dictionary of ``attrs`` attributes for a class, whose keys are the attribute names. `290 <https://github.com/python-attrs/attrs/issues/290>`_, `349 <https://github.com/python-attrs/attrs/issues/349>`_ - The order of attributes that are passed into ``attr.make_class()`` or the ``these`` argument of ``attr.s()`` is now retained if the dictionary is ordered (i.e. ``dict`` on Python 3.6 and later, ``collections.OrderedDict`` otherwise). Before, the order was always determined by the order in which the attributes have been defined which may not be desirable when creating classes programatically. `300 <https://github.com/python-attrs/attrs/issues/300>`_, `339 <https://github.com/python-attrs/attrs/issues/339>`_, `343 <https://github.com/python-attrs/attrs/issues/343>`_ - In slotted classes, ``__getstate__`` and ``__setstate__`` now ignore the ``__weakref__`` attribute. `311 <https://github.com/python-attrs/attrs/issues/311>`_, `326 <https://github.com/python-attrs/attrs/issues/326>`_ - Setting the cell type is now completely best effort. This fixes ``attrs`` on Jython. We cannot make any guarantees regarding Jython though, because our test suite cannot run due to dependency incompatabilities. `321 <https://github.com/python-attrs/attrs/issues/321>`_, `334 <https://github.com/python-attrs/attrs/issues/334>`_ - If ``attr.s`` is passed a *these* argument, it will not attempt to remove attributes with the same name from the class body anymore. `322 <https://github.com/python-attrs/attrs/issues/322>`_, `323 <https://github.com/python-attrs/attrs/issues/323>`_ - The hash of ``attr.NOTHING`` is now vegan and faster on 32bit Python builds. `331 <https://github.com/python-attrs/attrs/issues/331>`_, `332 <https://github.com/python-attrs/attrs/issues/332>`_ - The overhead of instantiating frozen dict classes is virtually eliminated. `336 <https://github.com/python-attrs/attrs/issues/336>`_ - Generated ``__init__`` methods now have an ``__annotations__`` attribute derived from the types of the fields. `363 <https://github.com/python-attrs/attrs/issues/363>`_ - We have restructured the documentation a bit to account for ``attrs``' growth in scope. Instead of putting everything into the `examples <http://www.attrs.org/en/stable/examples.html>`_ page, we have started to extract narrative chapters. So far, we've added chapters on `initialization <http://www.attrs.org/en/stable/init.html>`_ and `hashing <http://www.attrs.org/en/stable/hashing.html>`_. Expect more to come! `369 <https://github.com/python-attrs/attrs/issues/369>`_, `370 <https://github.com/python-attrs/attrs/issues/370>`_ ---- ``` </details> <details> <summary>Links</summary> - PyPI: https://pypi.org/project/attrs - Changelog: https://pyup.io/changelogs/attrs/ - Homepage: http://www.attrs.org/ </details> ### Update [twisted[tls]](https://pypi.org/project/twisted) from **17.9.0** to **18.4.0**. <details> <summary>Changelog</summary> ### 18.4.0 ``` =========================== Features -------- - The --port/--https arguments to web plugin are now deprecated, in favor of --listen.

The --listen argument can be given multiple times to listen on multiple ports. (6670) - Twisted now requires zope.interface 4.4.2 or higher across all platforms and Python versions. (8149) - The osx_platform setuptools extra has been renamed to macos_platform, with the former name being a compatibility alias. (8848) - Zsh completions are now provided for the twist command. (9338) - twisted.internet.endpoints.HostnameEndpoint now has a __repr__ method which includes the host and port to which the endpoint connects. (9341) Bugfixes -------- - twistd now uses the UID's default GID to initialize groups when --uid is given but --gid is not. This prevents an unhandled TypeError from being raised when os.initgroups() is called. (4442) - twisted.protocols.basic.LineReceiver checks received lines' lengths against its MAX_LENGTH only after receiving a complete delimiter. A line ending in a multi-byte delimiter like '\r\n' might be split by the network, with the first part arriving before the rest; previously, LineReceiver erroneously disconnected if the first part, e.g. 'zzzz....\r' exceeded MAX_LENGTH. LineReceiver now checks received data against MAX_LENGTH plus the delimiter's length, allowing short reads to complete a line. (6556) - twisted.protocols.basic.LineOnlyReceiver disconnects the transport after receiving a line that exceeds MAX_LENGTH, like LineReceiver. (6557) - twisted.web.http.Request.getClientIP now returns the host part of the client's address when connected over IPv6. (7704) - twisted.application.service.IService is now documented as requiring the 'running', 'name' and 'parent' attributes (the documentation previously implied they were required, but was unclear). (7922) - twisted.web.wsgi.WSGIResource no longer raises an exception when a client connects over IPv6. (8241) - When using TLS enable automatic ECDH curve selection on OpenSSL 1.0.2+ instead of only supporting P-256 (9210) - twisted.trial._dist.worker and twisted.trial._dist.workertrial consistently pass bytes, not unicode to AMP. This fixes "trial -j" on Python 3. (9264) - twisted.trial.runner now uses the 'importlib' module instead of the 'imp' module on Python 3+. This eliminates DeprecationWarnings caused by importing 'imp' on Python 3. (9275) - twisted.web.client.HTTP11ClientProtocol now closes the connection when the server is sending a header line which is longer than he line limit of twisted.protocols.basic.LineReceiver.MAX_LENGTH. (9295) - twisted.python.failure now handles long stacktraces better; in particular it will log tracebacks for stack overflow errors. (9301) - The "--_shell-completion" argument to twistd now works on Python 3. (9303) - twisted.python.failure.Failure now raises the wrapped exception in Python3, and self (Failure) n Python2 when trap() is called without a matching exception (9307) - Writing large amounts of data no longer implies repeated, expensive copying under Python 3. Python 3's write speeds are now as fast as Python 2's. (9324) - twisted.protocols.postfix now properly encodes errors which are unicode strings to bytes. (9335) - twisted.protocols.policies.ProtocolWrapper and twisted.protocols.tls.TLSMemoryBIOProtocol no longer create circular references that keep protocol instances in memory after connection is closed. (9374) - twisted.conch.ssh.transport.SSHTransportBase no longer strips trailing spaces from the SSH version string of the connected peer. (9377) - `trial -j` no longer crashes on Python 2 on test failure messages containing non-ASCII bytes. (9378) - RSA keys replaced with 2048bit ones in twisted.conch.test.keydata in order to be compatible with OpenSSH 7.6. (9388) - AsyncioSelectorReactor uses the global policy's event loop. asyncio libraries that retrieve the running event loop with get_event_loop() will now receive the one used by AsyncioSelectorReactor. (9390) Improved Documentation ---------------------- - public attributes of `twisted.logger.Logger` are now documented as attributes. (8157) - List indentation formatting errors have been corrected throughout the documentation. (9256) Deprecations and Removals ------------------------- - twisted.protocols.basic.LineOnlyReceiver.lineLengthExceeded no longer returns twisted.internet.error.ConnectionLost. It instead directly disconnects the transport and returns None. (6557) - twisted.python.win32.getProgramsMenuPath and twisted.python.win32.getProgramFilesPath were deprecated in Twisted 15.3.0 and have now been removed. (9312) - Python 3.3 is no longer supported. (9352) Misc ---- - 7033, 8887, 9204, 9289, 9291, 9292, 9293, 9302, 9336, 9355, 9356, 9364, 9375, 9381, 9382, 9389, 9391, 9393, 9394, 9396 Conch ----- Bugfixes ~~~~~~~~ - twisted.plugins.cred_unix now properly converts a username and password from bytes to str on Python 3. In addition, passwords which are encrypted with SHA512 and SH256 are properly verified. This fixes running a conch server with: "twistd -n conch -d /etc/ssh/ --auth=unix". (9130) - In twisted.conch.scripts.conch, on Python 3 do not write bytes directly to sys.stderr. On Python 3, this fixes remote SSH execution of a command which fails. (9344) Deprecations and Removals ~~~~~~~~~~~~~~~~~~~~~~~~~ - twisted.conch.ssh.filetransfer.FileTransferClient.wasAFile attribute has been removed as it serves no purpose. (9362) - Removed deprecated support for PyCrypto key objects in conch (9368) Web --- Features ~~~~~~~~ - The new twisted.iweb.IRequest.getClientAddress returns the IAddress provider representing the client's address. Callers should check the type of the returned value before using it. (7707) - Eliminate use of twisted.python.log in twisted.web modules. (9280) Bugfixes ~~~~~~~~ - Scripts ending with .rpy, .epy, and .cgi now execute properly in Twisted Web on Python 3. (9271) - twisted.web.http.Request and twisted.web.server.Request are once again hashable on Python 2, fixing a regression introduced in Twisted 17.5.0. (9314) Improved Documentation ~~~~~~~~~~~~~~~~~~~~~~ - Correct reactor docstrings for twisted.web.client.Agent and twisted.web.client._StandardEndpointFactory to communicate interface requirements since 17.1. (9274) - The examples for the "Twisted Web in 60 Seconds" tutorial have been fixed to work on Python 3. (9285) Deprecations and Removals ~~~~~~~~~~~~~~~~~~~~~~~~~ - twisted.iweb.IRequest.getClientIP is deprecated. Use twisted.iweb.IRequest.getClientAddress instead (see 7707). (7705) - twisted.web.iweb.IRequest.getClient and its implementations (deprecated in 2552) have been removed. (9395) Mail ---- Bugfixes ~~~~~~~~ - twistd.mail.scripts.mailmail has been ported to Python 3. (8487) - twisted.mail.bounce now works on Python 3. (9260) - twisted.mail.pop3 and twisted.mail.pop3client now work on Python 3. (9269) - SMTP authentication in twisted.mail.smtp now works better on Python 3, due to improved improved bytes vs unicode handling. (9299) Misc ~~~~ - 9310 Words ----- No significant changes. Names ----- No significant changes. ``` </details> <details> <summary>Links</summary> - PyPI: https://pypi.org/project/twisted - Changelog: https://pyup.io/changelogs/twisted/ - Homepage: http://twistedmatrix.com/ - Bugtracker: https://twistedmatrix.com/trac/ </details> ### Update [zope.interface](https://pypi.org/project/zope.interface) from **4.4.3** to **4.5.0**. <details> <summary>Changelog</summary> ### 4.5.0 ``` ------------------ - Drop support for 3.3, avoid accidental dependence breakage via setup.py.

So it’s time to depend on examples even less.
Although the sections on validators and converters are copied mostly verbatim from there. I’m not sure how to cull examples in a meaningful way? It could be a little briefer and just refer to the new chapter.
But it finally gives a good place to explain intricacies of initialization.
Feedback welcome!
