[ANN] Daily Windows builds of Python 3.x
by Steve Dower 08 Aug '17

08 Aug '17

Hi all As part of a deal with Zach Ware at PyCon, I agreed that if he removed the Subversion dependency from our builds, I would set up daily Windows builds of Python. Zach did an excellent job, and so I am now following through on my half of the deal :) For a while I've been uploading the official releases to nuget.org. These packages can be installed with nuget.exe (latest version always available at https://aka.ms/nugetclidl), which is quickly becoming a standard tool in Microsoft's build toolsets. It's very much a CI-focused package manager, rather than a user-focused one, and CI on Windows was previously an area where it was difficult to use Python. See the official feed at https://www.nuget.org/packages/python, and related packages pythonx86, python2 and python2x86. For people looking for an official "no installer" version of Python for Windows, this is it. And since all the infrastructure was there already, I decided to publish daily builds in a similar way to myget.org: https://www.myget.org/feed/python/package/nuget/pythondaily To install the latest daily build, run nuget.exe with this command: nuget.exe pythondaily -Source https://www.myget.org/F/python/api/v3/index.json (Note that if you already have a "pythondaily" package in that directory, nuget will consider the requirement satisfied. As I said, it's meant for reproducible CI builds rather than users who want to update things in the least amount of keystrokes :) ) The sys.version string contains the short commit hash. Please include this string when reporting bugs in these builds. Also, only the amd64 Release build is available pre-built. >>> sys.version '3.7.0a0 (remotes/origin/master:733d0f63c, Aug 8 2017, 15:56:14) [MSC v.1900 64 bit (AMD64)]' Hopefully this is valuable for people who want to include daily builds in their own test runs or validate recent bug fixes. Cheers, Steve

[RELEASED] Python 3.5.4 is now available
by Larry Hastings 08 Aug '17

08 Aug '17

On behalf of the Python development community and the Python 3.5 release team, I'm pleased to announce the availability of Python 3.5.4. Python 3.5.4 is the final 3.5 release in "bug fix" mode. The Python 3.5 branch has now transitioned into "security fixes mode"; all future improvements in the 3.5 branch will be security fixes only, and no conventional bug fixes will be merged. You can find Python 3.5.4 here: https://www.python.org/downloads/release/python-354/ Python 3.4.7 final will be released later today. Happy Pythoning, //arry/

SQLObject 3.4.0
by Oleg Broytman 05 Aug '17

05 Aug '17

Hello! I'm pleased to announce version 3.4.0, the first stable release of branch 3.4 of SQLObject. What's new in SQLObject ======================= Contributor for this release is Dr. Neil Muller. Features -------- * Python 2.6 is no longer supported. The minimal supported version is Python 2.7. Drivers (work in progress) -------------------------- * Encode binary values for py-postgresql driver. This fixes the last remaining problems with the driver. * Encode binary values for PyGreSQL driver using the same encoding as for py-postgresql driver. This fixes the last remaining problems with the driver. Our own encoding is needed because unescape_bytea(escape_bytea()) is not idempotent. See the comment for PQunescapeBytea at https://www.postgresql.org/docs/9.6/static/libpq-exec.html: This conversion is not exactly the inverse of PQescapeBytea, because the string is not expected to be "escaped" when received from PQgetvalue. In particular this means there is no need for string quoting considerations. * List all drivers in extras_require in setup.py. Minor features -------------- * Use base64.b64encode/b64decode instead of deprecated encodestring/decodestring. Tests ----- * Fix a bug with sqlite-memory: rollback transaction and close connection. The solution was found by Dr. Neil Muller. * Use remove-old-files.py from ppu to cleanup pip cache at Travis and AppVeyor. * Add test_csvimport.py more as an example how to use load_csv from sqlobject.util.csvimport. 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. SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB). 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.python.org/pypi/SQLObject/3.4.0 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 http://phdru.name/ phd(a)phdru.name Programmers don't die, they just GOSUB without RETURN.

Vulture 0.22
by Jendrik Seipp 04 Aug '17

04 Aug '17

Vulture - Find dead code ======================== Vulture finds unused code in Python programs. This is useful for cleaning up and finding errors in large code bases. If you run Vulture on both your library and test suite you can find untested code. Due to Python's dynamic nature, static code analyzers like Vulture are likely to miss some dead code. Also, code that is only called implicitly may be reported as unused. Nonetheless, Vulture can be a very helpful tool for higher code quality. Download ======== https://github.com/jendrikseipp/vulture http://pypi.python.org/pypi/vulture Features ======== * fast: static code analysis * lightweight: only one module * tested: tests itself and has complete test coverage * complements pyflakes and has the same output syntax * supports Python 2.6, 2.7 and 3.x News ==== 0.22 (2017-08-04) ----------------- * Detect unreachable code after ``return``, ``break``, ``continue`` and ``raise`` (thanks @RJ722). * Parse all variable and attribute names in new format strings. * Extend ast whitelist. Cheers, Jendrik

For security reasons, we don't use a third party public installation as default but warn if `math-output` is set to MathJax without specifying a URL. See math-output_ for details. * docutils/writers/html4css1: - Respect automatic table column sizing. * docutils/writers/latex2e/__init__.py - Handle class arguments for block-level elements by wrapping them in a "DUclass" environment. This replaces the special handling for "epigraph" and "topic" elements. * docutils/writers/odf_odt: - Language option sets ODF document's default language - Image width, scale, ... set image size in generated ODF. * tools/ - New front-end ``rst2html4.py``. cheers
