SQLObject 3.4.0
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.

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.

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
>>> p.fname
'John'
>>> p.mi = 'Q'
>>> p2 = Person.get(1)
>>> p2
>>> p is p2
True
Queries::
>>> p3 = Person.selectBy(lname="Doe")[0]
>>> p3
>>> pc = Person.select(Person.q.lname=="Doe").count()
>>> pc
1

Vulture 0.22
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.

PyCA cryptography 2.0.3 released
PyCA cryptography 2.0.3 has been released to PyPI. cryptography includes both high level recipes and low level interfaces to common cryptographic algorithms such as symmetric ciphers, message digests, and key derivation functions. We support Python 2.6-2.7, Python 3.4+, and PyPy. This release fixes an issue with weak linking symbols when compiling on macOS versions older than 10.12. There are no other changes. -Paul Kehrer (reaperhulk) -- https://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/
docutils 0.14 released
RELEASE-NOTES * docutils/docs/ref/docutils.dtd: - Enable validation of Docutils XML documents against the DTD: * docutils/parsers/rst/: - Added functionality: escaped whitespace in URI contexts. - Consistent handling of all whitespace characters in inline markup recognition. (May break documents that relied on some whitespace characters (NBSP, ...) *not* to be recognized as whitespace.) * docutils/utils/smartquotes.py: - Update quote definitions for et, fi, fr, ro, sv, tr, uk. - Add quote definitions for hr, hsb, hu, lv, sh, sl, sr. - Differentiate apostrophe from closing single quote (if possible). - Add command line interface for stand-alone use (requires 2.7). * docutils/writers/_html_base: - Provide default title in metadata. - The MathJax CDN shut down on April 30, 2017. 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 -- https://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/
