[ANN] Datatest 0.11.0 Released
by Shawn Brown Dec. 18, 2020

Dec. 18, 2020

I'm pleased to announce the release of Datatest version 0.11.0. Datatest implements a system of *validation* methods, *difference* classes, and *acceptance* context managers. It can be used directly in your own projects or as part of a testing framework like pytest or unittest. This is a large and long-awaited update. If you are upgrading from an older version of datatest, pay special attention to the installation steps below. HIGHLIGHTS INCLUDE: * Complete rewrite of Introduction, How-to, and Discussion docs: - https://datatest.readthedocs.io/ * Added extension accessors for tighter Pandas integration. * Added features for NumPy and Squint integration. * Fixed bug with `pytest-xdist` interoperability. * Modifies some user-facing APIs to improve usability. * Moved the query API into a separate project, **squint**: - https://pypi.org/project/squint/ * Moved `get_reader()` into a separate project, **get-reader**: - https://pypi.org/project/get-reader/ For more information see: - https://github.com/shawnbrown/datatest/blob/master/CHANGELOG LINKS: - PyPI: https://pypi.org/project/datatest/ - GitHub: https://github.com/shawnbrown/datatest - Docs: https://datatest.readthedocs.io/en/stable/ INSTALL OR UPDATE: The easiest way to install datatest is to use pip: `pip install datatest` If you aren't worried about supporting a codebase of older scripts, upgrade an existing installation with: `pip install --upgrade datatest` If you have an existing codebase of older datatest scripts, you should upgrade using the following steps: 1: Install datatest 0.10.0 first: `pip install --force-reinstall datatest==0.10.0` 2: Run your existing code and check for DeprecationWarnings. 3: Update the parts of your code that use deprecated features. 4: Once your code is running without DeprecationWarnings, install the latest version of datatest, 0.11.0: `pip install --upgrade datatest`

SQLObject 3.9.0
by Oleg Broytman Dec. 15, 2020

Dec. 15, 2020

Hello! I'm pleased to announce version 3.9.0, the first release of branch 3.9 of SQLObject. What's new in SQLObject ======================= Contributors for this release are: + Michael S. Root, Ameya Bapat - ``JSONCol``; + Jerry Nance - reported a bug with ``DateTime`` from ``Zope``. Features -------- * Add ``JSONCol``: a universal json column that converts simple Python objects (None, bool, int, float, long, dict, list, str/unicode to/from JSON using json.dumps/loads. A subclass of StringCol. Requires ``VARCHAR``/``TEXT`` columns at backends, doesn't work with ``JSON`` columns. * Extend/fix support for ``DateTime`` from ``Zope``. * Drop support for very old version of ``mxDateTime`` without ``mx.`` namespace. Drivers ------- * Support `mariadb <https://pypi.org/project/mariadb/>`_. CI -- * Run tests with Python 3.9 at Travis and AppVeyor. For a more complete list, please see the news: http://sqlobject.org/News.html What is SQLObject ================= SQLObject is an object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. It currently supports MySQL, PostgreSQL and SQLite; connections to other backends - Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB) - are lesser debugged). Python 2.7 or 3.4+ is required. Where is SQLObject ================== Site: http://sqlobject.org Development: http://sqlobject.org/devel/ Mailing list: https://lists.sourceforge.net/mailman/listinfo/sqlobject-discuss Download: https://pypi.org/project/SQLObject/3.9.0 News and changes: http://sqlobject.org/News.html StackOverflow: https://stackoverflow.com/questions/tagged/sqlobject Example ======= Create a simple class that wraps a table:: >>> from sqlobject import * >>> >>> sqlhub.processConnection = connectionForURI('sqlite:/:memory:') >>> >>> class Person(SQLObject): ... fname = StringCol() ... mi = StringCol(length=1, default=None) ... lname = StringCol() ... >>> Person.createTable() Use the object:: >>> p = Person(fname="John", lname="Doe") >>> p <Person 1 fname='John' mi=None lname='Doe'> >>> p.fname 'John' >>> p.mi = 'Q' >>> p2 = Person.get(1) >>> p2 <Person 1 fname='John' mi='Q' lname='Doe'> >>> p is p2 True Queries:: >>> p3 = Person.selectBy(lname="Doe")[0] >>> p3 <Person 1 fname='John' mi='Q' lname='Doe'> >>> pc = Person.select(Person.q.lname=="Doe").count() >>> pc 1 Oleg. -- Oleg Broytman https://phdru.name/ phd(a)phdru.name Programmers don't die, they just GOSUB without RETURN.

[ANN] Pycopy/pycopy-lib 3.4.0, a minimalist Python dialect
by Paul Sokolovsky Dec. 10, 2020

Dec. 10, 2020

Hello, Pycopy is a minimalist, lightweight, resource-efficient implementation of Python(-like) language. Pycopy to CPython is a similar thing as Scheme to Common Lisp. Executable sizes of 300-400KB, instant startup, no need to carry around large monolithic library consisting largely of legacy modules - some but not all of Pycopy's features. Project page: https://github.com/pfalcon/pycopy Now has website too: https://pycopy.github.io/ The 3.4.0 release implements initial version of "strict execution mode" support, which is roughly a way to enforce constantness at the runtime, the complete proposal was posted to the python-ideas mailing list: https://mail.python.org/archives/list/python-ideas@python.org/thread/KGN4Q2… Pycopy's standard library, pycopy-lib https://github.com/pfalcon/pycopy-lib , also sees continued development, in particular the "re" module compatibility with CPython was largely improved. Prebuilt binaries of this release are available at https://github.com/pfalcon/pycopy/releases/tag/v3.4.0 More details about Pycopy ------------------------- Pycopy strives to define a core language features suitable to easily develop efficient software, while allow for extensibility to a wider (and much more bloaty and less efficient) set of features for compatibility with existing software. Pycopy doesn't come with bulky hazardous lead-acid batteries. Instead, a set of a few core modules are included builtin: inspired, being a noticeable subset, and a little bit of extension, of the corresponding CPython modules. Also, clearly namespaced, to still allow room to implement fully compatible CPython modules. These new modules aren't intended to be an adhoc thing, just an alternative API with a constraint of minimality. Implementation of that API also exists for CPython (WIP), allowing Pycopy -> CPython forward compatibility. The rest is handled outside the core language, via a separate project, pycopy-lib: https://github.com/pfalcon/pycopy-lib , which strives to port CPython stdlib to Pycopy, while, where needed, provide more lightweight module variants and extensions. Pycopy is a full-stack project, with ecosystem including a web micro-framework, pure-Python Python parser, FFMPEG bindings, SDL bindings, LLVM bindings, etc.: https://github.com/topics/pycopy -- Best regards, Paul mailto:pmiscml@gmail.com

PyCA cryptography 3.3 released
by Paul Kehrer Dec. 9, 2020

Dec. 9, 2020

PyCA cryptography 3.3 has been released to PyPI. cryptography includes both high level recipes and low level interfaces to common cryptographic algorithms such as symmetric ciphers, asymmetric algorithms, message digests, X509, key derivation functions, and much more. We support Python 2.7, Python 3.6+, and PyPy. Please note that this is the final version that will support Python 2.7! Changelog (https://cryptography.io/en/latest/changelog/): * BACKWARDS INCOMPATIBLE: Support for Python 3.5 has been removed due to low usage and maintenance burden. * BACKWARDS INCOMPATIBLE: The GCM and AESGCM now require 64-bit to 1024-bit (8 byte to 128 byte) initialization vectors. This change is to conform with an upcoming OpenSSL release that will no longer support sizes outside this window. * BACKWARDS INCOMPATIBLE: When deserializing asymmetric keys we now raise ValueError rather than UnsupportedAlgorithm when an unsupported cipher is used. This change is to conform with an upcoming OpenSSL release that will no longer distinguish between error types. * BACKWARDS INCOMPATIBLE: We no longer allow loading of finite field Diffie-Hellman parameters of less than 512 bits in length. This change is to conform with an upcoming OpenSSL release that no longer supports smaller sizes. These keys were already wildly insecure and should not have been used in any application outside of testing. * Updated Windows, macOS, and manylinux wheels to be compiled with OpenSSL 1.1.1i. * Python 2 support is deprecated in cryptography. This is the last release that will support Python 2. * Added the recover_data_from_signature() function to RSAPublicKey for recovering the signed data from an RSA signature. -Paul Kehrer (reaperhulk)
