rJSmin 1.0.8
by André Malo Feb. 12, 2014

Feb. 12, 2014

Hello World, I'm pleased to announce version 1.0.8 of rJSmin. About rJSmin ============ rJSmin is a javascript minifier written in python. The minifier is based on the semantics of jsmin.c by Douglas Crockford. The module is a re-implementation aiming for speed, so it can be used at runtime (rather than during a preprocessing step). Usually it produces the same results as the original jsmin.c. It differs in the following ways: - there is no error detection: unterminated string, regex and comment literals are treated as regular javascript code and minified as such. - Control characters inside string and regex literals are left untouched; they are not converted to spaces (nor to \n) - Newline characters are not allowed inside string and regex literals, except for line continuations in string literals (ECMA-5). - "return /regex/" is recognized correctly. - "+ +" and "- -" sequences are not collapsed to "++" or "--" - Newlines before ! operators are removed more sensibly - Comments starting with an exclamation mark ('!') can be kept optionally - rJSmin does not handle streams, but only complete strings. (However, the module provides a "streamy" interface). About Release 1.0.8 =================== This release adds the capability to keep comments starting with an exclamation mark (/*! bang comments */). Support for Python 3.4 was added. The benchmarks were updated. Supported Python Versions ========================= * Python 2.4 - 2.7 * Python 3.1 - 3.4 * PyPy 1.9, 2.0 * Jython 2.5, 2.7 (Python only) License ======= rJSmin is available under the terms and conditions of the "Apache License, Version 2.0." Links ===== * Homepage + Documentation: http://opensource.perlig.de/rjsmin/ * PyPI: https://pypi.python.org/pypi/rjsmin * Github: https://github.com/ndparker/rjsmin * License: http://www.apache.org/licenses/LICENSE-2.0 André "nd" Malo

ANN: eGenix mxODBC Connect 2.0.4 - Python ODBC Database Interface
by eGenix Team: M.-A. Lemburg Feb. 12, 2014

Feb. 12, 2014

________________________________________________________________________ ANNOUNCING eGenix.com mxODBC Connect Python ODBC Database Interface Version 2.0.4 mxODBC Connect is our commercially supported client-server product for connecting Python applications to relational databases in a truly platform independent way. This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-mxODBC-Connect-2.0.4-GA.html ________________________________________________________________________ INTRODUCTION The mxODBC Connect Database Interface for Python allows users to easily connect Python applications to all major databases on the market today in a highly portable, convenient and secure way. Python Database Connectivity the Easy Way ----------------------------------------- Unlike our mxODBC Python extension, mxODBC Connect is designed as client-server application, so you no longer need to find production quality ODBC drivers for all the platforms you target with your Python application. Instead you use an easy to install royalty-free Python client library which connects directly to the mxODBC Connect database server over the network. This makes mxODBC Connect a great basis for writing cross-platform multi-tier database applications and utilities in Python, especially if you run applications that need to communicate with databases such as MS SQL Server and MS Access, Oracle Database, IBM DB2 and Informix, Sybase ASE and Sybase Anywhere, MySQL, PostgreSQL, SAP MaxDB and many more, that run on Windows or Linux machines. Ideal for Database Driven Client Applications --------------------------------------------- By removing the need to install and configure ODBC drivers on the client side and dealing with complicated network setups for each set of drivers, mxODBC Connect greatly simplifies deployment of database driven client applications, while at the same time making the network communication between client and database server more efficient and more secure. For more information, please have a look at the mxODBC Connect product page, in particular, the full list of available features. For more information, please see the product page: http://www.egenix.com/products/python/mxODBCConnect/ ________________________________________________________________________ NEWS The 2.0.4 release of mxODBC Connect includes the following enhancements and fixes: Security Enhancements --------------------- * Upgraded client and server to the most recent eGenix pyOpenSSL Distribution 0.13.3.1.0.1.6. See http://egenix.com/go52 for details. * Authentication errors are now reported with the SYSTEM_ERROR log level, making them visible using the default server side log level setting. Server Enhancements ------------------- * Updated the server to use eGenix mxODBC 3.2.3 for database connectivity. See http://egenix.com/go45 for details. * Added new server connection configuration setting connection_cursortype which allows modifying the default cursor type (using the new connection.cursortype attribute value; see http://egenix.com/go42) without having to modify the client side applications. The setting can be applied on a per connection basis for enhanced flexibility. * The mxODBC DataDirect subpackage is now built against the current DataDirect ODBC manager version 7.1.2. Client Enhancements ------------------- * Fixed a problem with the .warningformat attribute not working as expected on cursors and connections. Performance Enhancements ------------------------ * MS SQL Server performance can be much enhanced, and increased to levels beyond that of mxODBC Connect 2.0.2 and previous releases, by adjusting the default cursor type to forward-only cursors instead of static cursors. mxODBC Connect 2.0.4 makes this possible without having to change client side applications by modifying the server-config.ini file as follows: [Connection_Example] ... # Use the faster forward-only cursors on this connection connection_cursortype = SQL.CURSOR_FORWARD_ONLY The performance increase compared to mxODBC Connect 2.0.2 is enormous: from 2-3x faster executes/fetches for average queries, up to 300x faster for simple cases. In mxODBC Connect 2.1, we will switch to using forward-only cursors per default for all database backends. * IBM DB2 can benefit from the same performance enhancements using forward-only cursors. The effect is a lot smaller, but still noticeable: up to 2x faster executes/fetches with forward-only cursors, compared to mxODBC Connect 2.0.2. For the full set of changes, please check the mxODBC Connect change log: http://www.egenix.com/products/python/mxODBCConnect/changelog.html mxODBC Connect 2.0 Highlights ----------------------------- mxODBC Connect 2.0 was released on 2012-08-20. These are the most important highlights: * mxODBC Connect Server now uses mxODBC 3.2 internally and makes its API available in the mxODBC Connect Client. This is a major step forward from the mxODBC 3.0 version used in mxODBC Connect Server 1.0. * We've added native Windows x64 builds. * mxODBC Connect Client now integrates directly with gevent, allowing client applications to run asynchronous tasks while performing remote database queries. Please see the release announcement for full details: http://www.egenix.com/company/news/eGenix-mxODBC-Connect-2.0.0-GA.html ________________________________________________________________________ UPGRADING You are encouraged to upgrade to this latest mxODBC Connect release. When upgrading, please always upgrade both the server and the client installations to the same version - even for patch level releases. Customers who have purchased mxODBC Connect 2.0 licenses can continue to use their licenses with this patch level release.

ANN: A new version (0.3.6) of python-gnupg has been released.
by Vinay Sajip Feb. 6, 2014

Feb. 6, 2014

A new version of the Python module which wraps GnuPG has been released. What Changed? ============= This is an enhancement and bug-fix release, but the bug-fixes include some security improvements, so all users are encouraged to upgrade. See the project website ( http://code.google.com/p/python-gnupg/ ) for more information. Summary: Enabled fast random tests on gpg as well as gpg2. Avoided deleting temporary file to preserve its permissions. Avoided writing passphrase to log. Added export-minimal and armor options when exporting keys. Added verify_data() method to allow verification of signatures in memory. Regularised end-of-line characters in ths source code. Rectified problems with earlier fix for shell injection. The current version passes all tests on Windows (CPython 2.4, 2.5, 2.6, 3.1, 2.7 and Jython 2.5.1) and Ubuntu (CPython 2.4, 2.5, 2.6, 2.7, 3.0, 3.1, 3.2). On Windows, GnuPG 1.4.11 has been used for the tests. 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...(a)gamma.com>']}, { ... 'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A', 'keyid': '0C5FEFA7A921FC4A', 'length': '1024', ... 'uids': ['', 'Danny Davis (A test user) <danny.da...(a)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' For more information, visit http://code.google.com/p/python-gnupg/ - as always, your feedback is most welcome (especially bug reports, patches and suggestions for improvement). Enjoy! Cheers Vinay Sajip Red Dove Consultants Ltd.
