[RELEASE] Python 3.6.0b1 is now available
by Ned Deily 12 Sep '16

12 Sep '16

On behalf of the Python development community and the Python 3.6 release team, I'm happy to announce the availability of Python 3.6.0b1. 3.6.0b1 is the first of four planned beta releases of Python 3.6, the next major release of Python, and marks the end of the feature development phase for 3.6. Among the new major new features in Python 3.6 are: * PEP 468 - Preserving the order of **kwargs in a function * PEP 487 - Simpler customization of class creation * PEP 495 - Local Time Disambiguation * PEP 498 - Literal String Formatting * PEP 506 - Adding A Secrets Module To The Standard Library * PEP 509 - Add a private version to dict * PEP 515 - Underscores in Numeric Literals * PEP 519 - Adding a file system path protocol * PEP 520 - Preserving Class Attribute Definition Order * PEP 523 - Adding a frame evaluation API to CPython * PEP 524 - Make os.urandom() blocking on Linux (during system startup) * PEP 525 - Asynchronous Generators (provisional) * PEP 526 - Syntax for Variable Annotations (provisional) * PEP 528 - Change Windows console encoding to UTF-8 (provisional) * PEP 529 - Change Windows filesystem encoding to UTF-8 (provisional) * PEP 530 - Asynchronous Comprehensions Please see "What’s New In Python 3.6" for more information: https://docs.python.org/3.6/whatsnew/3.6.html You can find Python 3.6.0b1 here: https://www.python.org/downloads/release/python-360b1/ Beta releases are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. We strongly encourage maintainers of third-party Python projects to test with 3.6 during the beta phase and report issues found to bugs.python.org as soon as possible. While the release is feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (2016-12-05). Our goal is have no changes after rc1. To achieve that, it will be extremely important to get as much exposure for 3.6 as possible during the beta phase. Please keep in mind that this is a preview release and its use is not recommended for production environments The next planned release of Python 3.6 will be 3.6.0b2, currently scheduled for 2016-10-03. More information about the release schedule can be found here: https://www.python.org/dev/peps/pep-0494/ -- Ned Deily nad(a)python.org -- []

ANN: DiskCache 2.0.2 Released
by Grant Jenks 12 Sep '16

12 Sep '16

Announcing the release of DiskCache version 2.0.2 What is DiskCache? ---- [DiskCache][1] is an Apache2 licensed disk and file backed cache library, written in pure-Python, and compatible with Django. By leveraging a rock-solid database library and memory-mapped files, cache performance can match and exceed industry standard solutions. There’s no need for a C compiler or running another process. [Performance is a feature][2] and testing has 100% coverage with unit tests and hours of stress in production. [1]: http://www.grantjenks.com/docs/diskcache/ [2]: http://www.grantjenks.com/docs/diskcache/cache-benchmarks.html What's new in 2.0.2? ---- * All writes now explicitly use transactions internally. Significant performance improvements were observed with many concurrent processes. http://www.grantjenks.com/docs/diskcache/djangocache-benchmarks.html * Add atomic increment and decrement methods: incr and decr. http://www.grantjenks.com/docs/diskcache/api.html#diskcache.Cache.incr * Add atomic method "add" for setting non-existant items. http://www.grantjenks.com/docs/diskcache/api.html#diskcache.Cache.add * Add method "read" like "get" but returns open file handle. http://www.grantjenks.com/docs/diskcache/api.html#diskcache.Cache.read * Add methods to create and drop tag index to evict items by tag. http://www.grantjenks.com/docs/diskcache/tutorial.html#cache * Cache and FanoutCache now support iteration. http://www.grantjenks.com/docs/diskcache/api.html#diskcache.Cache.__iter__ * FanoutCache and DjangoCache methods support "retry" parameter for timeouts. http://www.grantjenks.com/docs/diskcache/tutorial.html#djangocache * Use reset method to update settings rather than setting attributes. http://www.grantjenks.com/docs/diskcache/api.html#diskcache.Cache.reset * BugFix: The size of small bytes objects was double-counted. * BugFix: FanoutCache now uses "size_limit / shards" to limit shard volume. * BugFix: Changing "cull_limit" to zero will now only disable culling. * BugFix: Allow binding "close" and "clear" as signal handlers. * Re-run benchmarks and update tables and graphs. * Many documentation improvements and more examples. Features ---- * Pure-Python * Fully Documented * Benchmark comparisons (alternatives, Django cache backends) * 100% test coverage * Days of stress testing in production * Performance matters * Django compatible API * Thread-safe and process-safe * Supports multiple eviction policies (LRU and LFU included) * Keys support “tag” metadata and eviction * Developed on Python 2.7 * Tested on CPython 2.7, 3.4, 3.5 and PyPy Links ---- - Documentation: http://www.grantjenks.com/docs/diskcache/ - Download: https://pypi.python.org/pypi/diskcache - Source: https://github.com/grantjenks/python-diskcache - Issues: https://github.com/grantjenks/python-diskcache/issues Please upgrade.

RevDB, a reverse debugger
by Armin Rigo 10 Sep '16

10 Sep '16

Hi all, It is my pleasure to announce the first beta release of RevDB: a "reverse debugger" for Python. A reverse debugger is a debugger where you can go forward and backward in time. RevDB is designed to track down the annoying, hard-to-reproduce bug in your Python program. It is based on PyPy, but it is useful even if you usually run your programs on CPython. Note that only Python 2.7 is implemented right now, and Win32 is not supported so far. https://bitbucket.org/pypy/revdb/ A bientôt, Armin Rigo

ANN: A new version (0.3.9) of python-gnupg has been released.
by Vinay Sajip 10 Sep '16

10 Sep '16

A new version of the Python module which wraps GnuPG has been released. What Changed? ============= This is an enhancement and bug-fix release, and all users are encouraged to upgrade. See the project website [1] for more information. Brief summary: * Fixed #38: You can now request information about signatures against keys. Thanks to SunDwarf for the suggestion and patch, which was used as a basis for this change. * Fixed #49: When exporting keys, no attempt is made to decode the output when armor=False is specified. * Fixed #53: A ``FAILURE`` message caused by passing an incorrect passphrase is handled. * Handled ``EXPORTED`` and ``EXPORT_RES`` messages while exporting keys. Thanks to Marcel Pörner for the patch. * Fixed #54: Improved error message shown when gpg is not available. * Fixed #55: Added support for ``KEY_CONSIDERED`` while verifying. * Avoided encoding problems with filenames under Windows. Thanks to Kévin Bernard-Allies for the patch. * Fixed #57: Used a better mechanism for comparing keys. This release [2] has been signed with my code signing key: Vinay Sajip (CODE SIGNING KEY) <vina... at yahoo.co.uk> Fingerprint: CA74 9061 914E AC13 8E66 EADB 9147 B477 339A 9B86 What Does It Do? ================ The gnupg module allows Python programs to make use of the functionality provided by the Gnu Privacy Guard (abbreviated GPG or GnuPG). Using this module, Python programs can encrypt and decrypt data, digitally sign documents and verify digital signatures, manage (generate, list and delete) encryption keys, using proven Public Key Infrastructure (PKI) encryption technology based on OpenPGP. This module is expected to be used with Python versions >= 2.4, as it makes use of the subprocess module which appeared in that version of Python. This module is a newer version derived from earlier work by Andrew Kuchling, Richard Jones and Steve Traugott. A test suite using unittest is included with the source distribution. Simple usage: >>> import gnupg >>> gpg = gnupg.GPG(gnupghome='/path/to/keyring/directory') >>> gpg.list_keys() [{ ... 'fingerprint': 'F819EE7705497D73E3CCEE65197D5DAC68F1AAB2', 'keyid': '197D5DAC68F1AAB2', 'length': '1024', 'type': 'pub', 'uids': ['', 'Gary Gross (A test user) <gary.gr... at gamma.com>']}, { ... 'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A', 'keyid': '0C5FEFA7A921FC4A', 'length': '1024', ... 'uids': ['', 'Danny Davis (A test user) <danny.da... at delta.com>']}] >>> encrypted = gpg.encrypt("Hello, world!", ['0C5FEFA7A921FC4A']) >>> str(encrypted) '-----BEGIN PGP MESSAGE-----\nVersion: GnuPG v1.4.9 (GNU/Linux)\n \nhQIOA/6NHMDTXUwcEAf . -----END PGP MESSAGE-----\n' >>> decrypted = gpg.decrypt(str(encrypted), passphrase='secret') >>> str(decrypted) 'Hello, world!' >>> signed = gpg.sign("Goodbye, world!", passphrase='secret') >>> verified = gpg.verify(str(signed)) >>> print "Verified" if verified else "Not verified" 'Verified' As always, your feedback is most welcome (especially bug reports [3], patches and suggestions for improvement, or any other points via the mailing list/discussion group [4]). Enjoy! Cheers Vinay Sajip Red Dove Consultants Ltd.

python-can 1.5 release
by Brian Thorne 10 Sep '16

10 Sep '16

The can package provides controller area network support for Python developers; providing common abstractions to different hardware devices, and a suite of utilities for sending and receiving messages on a can bus. The library supports Python 2.7, Python 3.3+ and runs on Mac, Linux and Windows. I'm happy to announce a new version of python-can has been released to PyPi. It can be installed using `pip install python-can` (of course). This has been cooking in a development branch for a few months with plenty of changes and bug fixes. Documentation has been updated quite substantially, a virtual interface has been added and a consistent filtering api has been added. In particular a special thanks to Christian Sandberg who has made major contributions to this release. Note the 1.6 version plans to drop the implementation of the J1939 protocol to better focus on CAN.
