MicroPython 1.3.7 released
by Paul Sokolovsky 08 Dec '14

08 Dec '14

Hello, MicroPython is a Python3 language implementation which scales down to run on microcontrollers with tens of Ks of RAM and few hundreds of Ks of code size. Besides microcontrollers, it's also useful for small embedded Linux systems, where storage space is limited, for embedding as a scripting engine into standalone applications, where quick startup time is needed, etc. http://micropython.org/ https://github.com/micropython/micropython It went several months since the original announcement of MicroPython 1.0 (https://mail.python.org/pipermail/python-list/2014-June/672994.html), there were number of releases in the meantime, but we were too busy implementing new features, so this announcement provides just high-level overview of changes: * Basic Unicode support added (thanks to Chris Angelico for driving the effort) * More functionality of standard types and functions are implemented (for example, MicroPython can run subset of http.client module functionality from CPython3 stdlib). * Highly optimized for code size implementations of important Python modules are added. There offer subset of functionality and prefixed with "u". For example, ure, uheapq, uzlib, uhashlib, ubinascii are provided. * Lots of microcontroller hardware bindings added and generalized. Besides core interpreter, there's also good progress on modules and applications: * MicroPython standard library project, https://github.com/micropython/micropython-lib , an effort to port/develop as much as possible Python stdlib modules to MicroPython, has good progress, with few dozens of modules available on PyPI already (pip-micropython wrapper is provided to install them). * An asyncio subset implementation, dubbed "uasyncio", is available and should be stable enough. * Proof of concept web microframework, "picoweb", based on uasyncio is being developed: https://github.com/pfalcon/picoweb * Lots of other projects available on github. Reference implementation of MicroPython runs on a microcontroller board with 1Mb Flash and 128Kb RAM, which should offer good platform for people interested in microcontroller usage (more info: http://micropython.org/). MicroPython can also be easily built and supported on Linux, MacOSX, and Windows systems (more info: https://github.com/micropython/micropython) -- Best regards, Paul mailto:pmiscml@gmail.com

ANN: A new version (0.3.7) of python-gnupg has been released.
by Vinay Sajip 07 Dec '14

07 Dec '14

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 [1] for more information. Brief summary: * Added an 'output' keyword parameter to the 'sign' and 'sign_file' methods, to allow writing the signature to a file. * Allowed specifying 'True' for the 'sign' keyword parameter, which allows use of the default key for signing and avoids having to specify a key id when it's desired to use the default. * Used a uniform approach with subprocess on Windows and POSIX: shell=True is not used on either. * When signing/verifying, the status is updated to reflect any expired or revoked keys or signatures. * Handled 'NOTATION_NAME' and 'NOTATION_DATA' during verification. * Fixed #1, #16, #18, #20: Quoting approach changed, since now shell=False. * Fixed #14: Handled 'NEED_PASSPHRASE_PIN' message. * Fixed #8: Added a scan_keys method to allow scanning of keys without the need to import into a keyring. * Fixed #5: Added '0x' prefix when searching for keys. * Fixed #4: Handled 'PROGRESS' message during encryption. * Fixed #3: Changed default encoding to Latin-1. * Fixed #2: Raised ValueError if no recipients were specified for an asymmetric encryption request. * Handled 'UNEXPECTED' message during verification. * Replaced old range(len(X)) idiom with enumerate(). * Refactored ``ListKeys`` / ``SearchKeys`` classes to maximise use of common functions. * Fixed GC94: Added ``export-minimal`` and ``armor`` options when exporting keys. This addition was inadvertently left out of 0.3.6. This release [2] has been signed with my code signing key: Vinay Sajip (CODE SIGNING KEY) <vinay_sajip(a)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.

ANN: 'tsshbatch' Server Automation Tool Version 1.204 Released
by Tim Daneliuk 05 Dec '14

05 Dec '14

'tsshbatch' Version 1.204 is now released and available for download at: http://www.tundraware.com/Software/tsshbatch This is a major update with many bug fixes and improvements. Existing users will want to update sooner rather than later. The last public release was 1.177. --------------------------------------------------------------------- What Is 'tsshbatch'? -------------------- 'tsshbatch' is a server automation tool to enable you to issue commands to many servers without having to log into each one separately. When writing scripts, this overcomes the 'ssh' limitation of not being able to specify the password on the command line. 'tsshbatch' also understands basic 'sudo' syntax and can be used to access a server, 'sudo' a command, and then exit. 'tsshbatch' thus allows you to write complex, hands-off scripts that issue commands to many servers without the tedium of manual login and 'sudo' promotion. System administrators, especially, will find this helpful when working in large server farms. 'tsshbatch' is written in Python and requires the 'paramiko library. It has been tested on various Linux and FreeBSD variants. WHATSNEW For 'tsshbatch' 1.204 (Thu Dec 4 17:49:30 CST 2014) ---------------------------------------------------------------------- [NEW FEATURES] - Added the following builtin variables: __DATE__ # Date in YYYYMMDD format __DATETIME__ # Date and time in YYYYMMDDHHMMSS format __HOSTNAME__ # Full name of current host as passed to program __HOSTNUM__ # Count of host being processed, starting at 1 __HOSTSHORT__ # Leftmost component of hostname as passed to program __TIME__ # Time in HHMMSS format - Added an "execution variable". This runs a command of your choosing (on the local machine) and assigns the results to a user-defined variable. - Added -E to redirect all stderr output to stdout instead, - Added -T timeout option (default is 15 sec). - Added -a to allow program to continue after file transfer error. - Added -l logging option. Defaults to /dev/null. This fixes the error that was previously being reported: "No handlers could be found for logger "paramiko.transport" - Added -q for "quieter" output. [CHANGES] - File transfers now properly preserve the file's permissions. - Changed hostname separator from ':' to '-' when using the -G command. - The <HOSTNAME> and <HOSTSHORT> builtins have been replaced with the new builtins described above. - Error messages now more consistent and clear. - Test mode now expands variable references to their values for all variables except the builtins above (which are only evaluated at runtime). - Documentation has been rewritten and improved considerably. [BUG FIXES] - Fixed bug that prevented the proper dereferencing of __HOSTNAME|SHORT__ (formerly <HOSTNAME|SHORT>) in file transfer specifications. - Fixed bug that prevented variable substitution in hostnames. - Fixed bug that prevented '.define' variables from being substituted in file transfer specifications. - Fixed bug that only recognized sudo invocations if they were the first statement on a command line. All instances of the string "sudo " will now force sudo password prompting and processing. That string is ignored if it appears inside single- or double quotes. - Fixed a bug that intermittently occurred during password-based auth sessions because ssh-agent and key searching were still being used. - Fixed error reporting blowout when key-exchange auth fails. ---------------------------------------------------------------------------- Tim Daneliuk tundra(a)tundraware.com PGP Key: http://www.tundraware.com/PGP/ -- ---------------------------------------------------------------------------- Tim Daneliuk tundra(a)tundraware.com PGP Key: http://www.tundraware.com/PGP/

ANN: eGenix mxODBC Connect 2.1.2 - Python Database Interface
by eGenix Team: M.-A. Lemburg 02 Dec '14

02 Dec '14

________________________________________________________________________ ANNOUNCING eGenix.com mxODBC Connect Python Database Interface Version 2.1.2 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-2.1.2-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 mxODBC Connect 2.1.2 is a patch level release of our successful mxODBC Connect product. In the last patch level release 2.1.1, we had put a lot of emphasis on enhancing the TLS/SSL setup of the mxODBC Connect product: https://cms.egenix.com/company/news/eGenix-mxODBC-Connect-2.1.1-GA.html In this release, we are fixing a pip installation problem, that occurred with the mxODBC Connect Client on a few platforms, as well as a some other minor issues we found: Security Enhancements --------------------- * OpenSSL cipher string list updated to explicitly disallow use of low security or export ciphers. mxODBC Connect Enhancements --------------------------- * Fixed a problem that could cause the mxODBC Connect Client to not install correctly with pip. * Successfully tested against Python 2.7.9, which will come with a new ssl module. * Fixed the package version number to show the correct release version. * Fixed OpenSSL warnings in the Unix installer and scripts. For the full set of changes, including those of the 2.1 series of mxODBC Connect, please check the mxODBC Connect change log: http://www.egenix.com/products/python/mxODBCConnect/changelog.html ________________________________________________________________________ UPGRADING You are encouraged to upgrade to this latest mxODBC Connect release.
