PyCA/cryptography 1.3 released
by Paul Kehrer 18 Mar '16

18 Mar '16

On behalf of all our contributors I am pleased to announce the release of PyCA/cryptography (https://github.com/pyca/cryptography) version 1.3. cryptography is a package which provides cryptographic recipes and primitives to Python developers. Our goal is for it to be your "cryptographic standard library". We support Python 2.6-2.7, Python 3.3+, and PyPy. Changelog (https://cryptography.io/en/latest/changelog/): * Added support for padding ANSI X.923 with ANSIX923. * Deprecated support for OpenSSL 0.9.8. Support will be removed in cryptography 1.4. * Added support for the PolicyConstraints X.509 extension including both parsing and generation using CertificateBuilder and CertificateSigningRequestBuilder. * Added is_signature_valid to CertificateSigningRequest. * Fixed an intermittent AssertionError when performing an RSA decryption on an invalid ciphertext, ValueError is now correctly raised in all cases. * Added from_issuer_subject_key_identifier(). ...and the typical miscellaneous improvements. Please see the website changelog for documentation and additional details. -Paul Kehrer (reaperhulk)

Twisted 16.0 Released
by Amber "Hawkie" Brown 15 Mar '16

15 Mar '16

On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 16.0! Twisted 16.0 brings some important changes, and some nice-to-haves as well. The major things are: - TLS endpoints have arrived! They're like the old `ssl:` endpoints, but support faster IPv4/IPv6 connections (using HostnameEndpoint) and always do hostname verification. - Conch now uses Cryptography instead of PyCrypto for underlying cryptographic operations. This means it'll work much better on PyPy! - Headers objects (notably used by t.web.server.Request) now support Unicode for the vast majority of cases, encoding keys to ISO-8859-1 and values to UTF-8. - WSGI support and AMP have been ported to Python 3, along with a handful of other modules. - More shedding of the past, with the GTK+ 1 reactor being removed. - Over 45 tickets have been closed since 15.5. For more information, check the NEWS file (link provided below). You can find the downloads at <https://pypi.python.org/pypi/Twisted> (or alternatively <http://twistedmatrix.com/trac/wiki/Downloads>). The NEWS file is also available at <https://github.com/twisted/twisted/blob/twisted-16.0.0/NEWS>. Many thanks to everyone who had a part in this release - the supporters of the Twisted Software Foundation, the developers who contributed code as well as documentation, and all the people building great things with Twisted! Twisted Regards, Amber Brown (HawkOwl) Twisted Release Manager

14 Mar '16

We have more than 280 great proposals for talks and trainings ready for EuroPython 2016 attendees to vote on. Please note that you have to have a ticket for EuroPython 2016, or have submitted a talk proposal yourself, in order to participate. Attendees: This is your chance to shape the conference ! You can search for topics and communicate your personal interest by casting your vote for each talk and training submission on our talk voting page: *** https://ep2016.europython.eu/en/talk-voting/ *** Talk Voting Talk voting will be open until Sunday, March 20. The program workgroup (WG) will then use the talk voting results as basis for their talk selection and announce the list of accepted talks late in March and the schedule shortly thereafter in April. With gravitational regards, -- EuroPython 2016 Team http://ep2016.europython.eu/ http://www.europython-society.org/

[ANN] aenum 1.3.0 released
by Ethan Furman 13 Mar '16

13 Mar '16

I am thrilled to announce the release of aenum 1.3.0 aenum --- advanced enumerations, named tuples, and named constants ================================================================== aenum includes the new Python stdlib enum module available in Python 3.4 backported for previous versions of Python from 2.7 and 3.3+ tested on 2.7, and 3.3+ An ``Enum`` is a set of symbolic names (members) bound to unique, constant values. Within an enumeration, the members can be compared by identity, and the enumeration itself can be iterated over. A ``NamedTuple`` is a class-based, fixed-length tuple with a name for each possible position accessible using attribute-access notation. A ``Constant`` is a class of named values whose members cannot be rebound; it lacks all other ``Enum`` capabilities, however; consequently, it can have duplicate values. There is also a ``module`` function that can insert the ``Constant`` class into ``sys.modules`` where it will appear to be a module whose top-level names cannot be rebound. Module Contents --------------- ``NamedTuple`` ~~~~~~~~~~~~ Base class for ``creating NamedTuples``, either by subclassing or via it's functional API. ``Constant`` ~~~~~~~~~~ Constant class for creating groups of constants. These names cannot be rebound to other values. ``Enum`` ~~~~~~ Base class for creating enumerated constants. ``IntEnum`` ~~~~~~~~~ Base class for creating enumerated constants that are also subclasses of ``int``. ``AutoNumberEnum`` ~~~~~~~~~~~~~~~~ Derived class that automatically assigns an ``int`` value to each member. ``OrderedEnum`` ~~~~~~~~~~~~~ Derived class that adds ``<``, ``<=``, ``>=``, and ``>`` methods to an ``Enum``. ``UniqueEnum`` ~~~~~~~~~~~~ Derived class that ensures only one name is bound to any one value. ``unique`` ~~~~~~~~ Enum class decorator that ensures only one name is bound to any one value. ``constant`` ~~~~~~~~~~ Descriptor to add constant values to an ``Enum`` ``convert`` ~~~~~~~~ Helper to transform target global variables into an ``Enum``. ``enum`` ~~~~~~ Helper for specifying keyword arguments when creating ``Enum`` members. ``export`` ~~~~~~~~ Helper for inserting ``Enum`` members into a namespace (usually ``globals()``. ``extend_enum`` ~~~~~~~~~~~~~ Helper for adding new ``Enum`` members after creation. ``module`` ~~~~~~~~ Function to take a ``Constant`` or ``Enum`` class and insert it into ``sys.modules`` with the affect of a module whose top-level constant and member names cannot be rebound. ``skip`` ~~~~~~ Descriptor to add a normal (non-``Enum`` member) attribute to an ``Enum`` or ``Constant``. Creating an Enum ---------------- Enumerations can be created using the ``class`` syntax, which makes them easy to read and write. To define an enumeration, subclass ``Enum`` as follows:: >>> from aenum import Enum >>> class Color(Enum): ... red = 1 ... green = 2 ... blue = 3 The ``Enum`` class is also callable, providing the following functional API:: >>> Animal = Enum('Animal', 'ant bee cat dog') >>> Animal <enum 'Animal'> >>> Animal.ant <Animal.ant: 1> >>> Animal.ant.value 1 >>> list(Animal) [<Animal.ant: 1>, <Animal.bee: 2>, <Animal.cat: 3>, <Animal.dog: 4>] Creating NamedTuples -------------------- Simple ^^^^^^ The most common way to create a new NamedTuple will be via the functional API:: >>> from aenum import NamedTuple >>> Book = NamedTuple('Book', 'title author genre', module=__name__) Advanced ^^^^^^^^ The simple method of creating ``NamedTuples`` requires always specifying all possible arguments when creating instances; failure to do so will raise exceptions. However, it is possible to specify both docstrings and default values when creating a ``NamedTuple`` using the class method:: >>> class Point(NamedTuple): ... x = 0, 'horizontal coordinate', 0 ... y = 1, 'vertical coordinate', 0 ... >>> Point() Point(x=0, y=0) Creating Constants ------------------ ``Constant`` is similar to ``Enum``, but do not support the ``Enum`` protocols, and have no restrictions on duplications:: >>> class K(Constant): ... PI = 3.141596 ... TAU = 2 * PI ... >>> K.TAU 6.283192 ------------------------------------------------------------------- Some of the inspirations: An Enum of Enums: http://stackoverflow.com/q/30471864/208880 C-like Enums: http://stackoverflow.com/q/29264941/208880 Extending Enums: http://stackoverflow.com/q/28126314/208880 Named constants: http://stackoverflow.com/q/31537316/208880

ANN: psutil 4.1.0 released
by Giampaolo Rodola' 12 Mar '16

12 Mar '16

About ===== psutil (python system and process utilities) is a cross-platform library for retrieving information on running processes and system utilization (CPU, memory, disks, network) in Python. It is useful mainly for system monitoring, profiling and limiting process resources and management of running processes. New features ========== - New psutil.cpu_stats() function returning number of CPU ctx switches interrupts, soft interrupts and syscalls. - Process.open_files() on Linux return 3 new fields: position, mode and flags: - Process.cpu_times() returns two new fields, 'children_user' and 'children_system'. - [Windows] psutil.cpu_times() return two new fields: "interrupt" and "dpc". Same for psutil.cpu_times_percent().
