NEW MAINTAINER for Pymacs
by François Pinard 24 Sep '04

24 Sep '04

Hello to everybody, and Emacs users in the Python community. The Pymacs project (described below) now has new maintainer: Syver Enstad <syver(a)inout.no>. I'm inviting Pymacs users to collaborate with Syver as nicely as they always did with me. Syver himself has always been known to me as a helpful, competent and enthusiastic Pymacs user. Future announcement or news, as well as any decision about Pymacs, will originate from Syver instead of me. Also, reports, questions or suggestions about Pymacs should ideally be sent directly to Syver. -------------------- Pymacs is a powerful tool which, once started from Emacs, allows both-way communication between Emacs Lisp and Python. Pymacs aims Python as an extension language for Emacs rather than the other way around, and this assymetry is reflected in some design choices. Within Emacs Lisp code, one may load and use Python modules. Python functions may themselves use Emacs services, and handle Emacs Lisp objects kept in Emacs Lisp space. See `http://pymacs.progiciels-bpi.ca' for more documentation, including the manual in HTML form. The canonical Pymacs distribution is available as `http://pymacs.progiciels-bpi.ca/archives/Pymacs.tar.gz'. Report problems and suggestions to Syver Enstad `mailto:syver@inout.no'. -- François Pinard http://www.iro.umontreal.ca/~pinard

cx_Freeze 3.0
by Anthony Tuininga 23 Sep '04

23 Sep '04

What is cx_Freeze? cx_Freeze is a set of utilities for freezing Python scripts into executables using many of the techniques found in Thomas Heller's py2exe, Gordon McMillan's Installer and the Freeze utility that ships with Python itself. Where do I get it? http://starship.python.net/crew/atuining http://www.computronix.com/utilities.shtml (it may be a few days before the second site is updated) What's new? 1) cx_Freeze now requires Python 2.3 or higher since it takes advantage of the ability of Python 2.3 and higher to import modules from zip files. This makes the freezing process considerably simpler and also allows for the execution of multiple frozen packages (such as found in COM servers or shared libraries) without requiring modification to the Python modules. 2) All external dependencies have been removed. cx_Freeze now only requires a standard Python distribution to do its work. 3) Added the ability to define the initialization scripts that cx_Freeze uses on startup of the frozen program. Previously, these scripts were written in C and could not easily be changed; now they are written in Python and can be found in the initscripts directory (and chosen with the new --init-script option to FreezePython). 4) The base executable ConsoleSetLibPath has been removed and replaced with the initscript ConsoleSetLibPath. 5) Removed base executables for Win32 services and Win32 COM servers. This functionality will be restored in the future but it is not currently in a state that is ready for release. If this functionality is required, please use py2exe or contact me for my work in progress. 6) The attribute sys.frozen is now set so that more recent pywin32 modules work as expected when frozen. 7) Added option --include-path to FreezePython to allow overriding of sys.path without modifying the environment variable PYTHONPATH. 8) Added option --target-dir/--install-dir to specify the directory in which the frozen executable and its dependencies will be placed. 9) Removed the option --shared-lib since it was used for building shared libraries and can be managed with the initscript SharedLib.py. 10) MakeFrozenBases.py now checks the platform specific include directory as requested by Michael Partridge. 11) Added option -O (or -OO) to FreezePython to set the optimization used when generating bytecode. 12) Improve the extension loader so that an ImportError is raised when the dynamic module is not located; otherwise an error about missing attributes is raised instead. 13) Extension loaders are only created when copying dependencies since the normal module should be loadable in the situation where a Python installation is available. 14) Allow for using a compiler other than gcc for building the frozen base executables by setting the environment variable CC. 15) Added support for replacing the paths in all frozen modules with something else (so that for example the path of the machine on which the freezing was done is not displayed in tracebacks) For those who used the betas over the past couple of months, here is what is new since 3.0 beta 3. 1) Ensure that ldd is only run on extension modules. 2) Allow for using a compiler other than gcc for building the frozen base executables by setting the environment variable CC. 3) Ensure that the import lock is not held while executing the main script; otherwise, attempts to import a module within a thread will hang that thread as noted by Roger Binns. 4) Added support for replacing the paths in all frozen modules with something else (so that for example the path of the machine on which the freezing was done is not displayed in tracebacks) -- Anthony Tuininga anthony(a)computronix.com Computronix Distinctive Software.

ANN: Logging Package v0.4.9.4 released
by vinay_sajip＠yahoo.co.uk 23 Sep '04

23 Sep '04

A new version of the Python logging package has been released. If you are using version 2.3 of later of Python, this release will not mean much to you - it is the same as recent checkins into Python CVS. However, this release fixes numerous bugs reported since the last independent release (0.4.9.2), and may be of interest to people using earlier versions of Python. What Does It Do? ================ The logging package offers the ability for any Python program to log events which occur during program execution. It's typically used to provide application diagnostics, warnings and error messages. In addition to capturing "what happened", "where it happened", "when it happened", "how important it is" and event specific data, you can configure, without changing the application source code, both the verbosity of logging and the routing of events to different destinations such as console, disk files, sockets, email addresses, Web servers, SOAP servers etc. etc. You can even change the configuration of a running program without stopping and restarting it! You can use the logging package in exception handlers, and it will include traceback information in the log. It's thread-safe, and very easy to use - just "import logging" and log away! Classes provided include: Logger - used to log messages for a particular area of an application. You can instantiate these wherever you want, there's no need to pass references to them around your application. You can log events based on importance levels of DEBUG (least important), INFO, WARN, ERROR, and CRITICAL (most important). You can define your own levels if the default levels don't meet your requirements. Handler - used to route events to particular destinations. Handlers included are: StreamHandler (for generalized streams, including console) FileHandler (for disk files - including log file rotation with size limits for log files) SocketHandler (for sending events to a TCP socket) DatagramHandler (for sending events to a UDP socket - faster, but less reliable than TCP) SMTPHandler (send events to arbitrary email addresses) HTTPHandler (send events to Web servers) SysLogHandler (send events to Unix syslog) MemoryHandler (batch up events and process them several at a time) NTEventLogHandler (send events to Windows NT event logs) There are also examples of XMLHandler and SOAPHandler in the distribution. Formatter - used to format events as text strings. Flexible "msg % arg_tuple" formatting is the basis for formatting, with flexible date/time formatting including ISO8601 and any strftime-based formats. Filter - used when filtering based on importance (DEBUG/INFO/WARNING/ERROR/CRITICAL) is not sufficient. The distribution includes examples of filters based on class matching, regular expression matching, value matching, and logger matching. In the unlikely event that you're daunted by all the apparent complexity, fear not. The package offers a simple function-based interface to allow very simple, almost casual use of the underlying features. In addition to the core logging functionality, you get the ability to configure logging using a ConfigParser-based text file format, a Tkinter-based GUI configurator which creates configuration files for you, and a simple network-based event receiver which receives events on TCP, UDP, HTTP and SOAP ports. This is suitable for testing and might perhaps serve as a model for your own event receivers. Also included are over 20 test scripts which serve both as test harnesses and examples of how to use the logging package. You can get more information from http://www.red-dove.com/python_logging.html There are "download" and "recent changes" links at the top of that page. API documentation is available at http://www.red-dove.com/logging/index.html As always, your feedback is most welcome (especially bug reports, patches and suggestions for improvement). Enjoy! Cheers Vinay Sajip Red Dove Consultants Ltd. Changes since the last independent release: =========================================== Added getLoggerClass() (thanks to Dave Wilson). Added exception handling in shutdown(). Sort globbed files in doRollover() in TimedRotatingFileHandler. Date formatting for SMTPHandler now uses email package where available. fileConfig() exception handling added for handler instantiation. Changed basicConfig() to add keyword arguments. Changes are backward-compatible. Refactored RotatingFileHandler to create a base class for rotating handlers. Added TimedRotatingFileHandler (thanks to Mark Davidson - minor changes have been made to the patch he supplied). Added error checking to log() to check that level is an integer, and raise a TypeError if not (as long as raiseExceptions is set). Fixed a bug in DatagramHandler.send() (thanks to Mario Aleppo and Enrico Sirola for pointing it out). Minor documentation corrections.

Pythonutils Update and Mailing List
by fuzzyman＠gmail.com 23 Sep '04

23 Sep '04

Yup.. another exciting new set of updates to the pythonutils scripts... ;-) Main Page - http://www.voidspace.org.uk/atlantibots/pythonutils.html Examples and small modules - http://www.voidspace.org.uk/atlantibots/recipebook.html Voidspace CGI Homepage - http://www.voidspace.xennos.com Pythonutils mailing list - http://voidspace.xennos.com/mailman/listinfo/pythonutils_voidspace.xennos.c… *NEW* auth_example Version 1.0.0 This is more of a tutorial than a script. It shows how to do basic authentication over http (a 401 error) using python. Several examples and explanation of what is happening at each stage. Useful for writing http clients or understanding http. Located at http://www.voidspace.org.uk/atlantibots/recipebook.html *NEW* Pythonutils Mailing List http://voidspace.xennos.com/mailman/listinfo/pythonutils_voidspace.xennos.c… For news about updates on all the Voidspace Python scripts and programs. This includes Nanagram, Dirwatcher, approx and ConfigObj et al. Also support, bugfixes and discussion. *UPDATE* approx Version 0.6.0 approx.py - cgiproxy for browsing in a restricted internet environment. Basic authentication works - including multiple users with multiple realms. Bug fixed in multiple user cookie support. Refactored to be cleaner and easier to work on. (Could still be better) Removed duplicate error handling code. In the event of errors (e.g. 404 error) the form to enter a URL is printed - making browsing easier... Reimplemented the POST method in a much simpler way - this way just proxies file uploads etc. (And imposes max file upload size) Added logging of requests - also for debugging. Some more helpful error messages and 'more correct' handling of unkown error codes. Proxying of request headers from the browser to the new request. *UPDATE* guestbook Version 1.1.1 guestbook.py - python guestbook with HTML templates. Email feature is now cross platform, not just for Linux servers. (Uses smtplib rather than sendmail). Attempting to fix a problem with carriage returns - odd. Changed license text. Various minor tinkerings.. Removed the need to have the script name in the template. Added the word poker to the list of banned words (to stop certain adverts). Added 'from_email' to the templates - which means this version of guestbook.py isn't compatible with an old template file. Added a work around so people won't notice (You *can* use old templates if you want to)... *UPDATE* http_test Version 1.3.0 http_test.py - script illustrating CGI environment and http. Useful for debugging. Online version as well. Will work with cookielib as well as ClientCookie. Will display an http error 'reason' if one exists... Print the form even in the event of errors. Will do basic authentication - stored username/passwords are valid for 2 minutes. *UPDATE* dataenc Version 1.1.5 dataenc.py - secure time limited logins over CGI and binary to ascii conversion. Increased speed in table_enc and table_dec. Version 1.1.4 Slight docs improvement. Slight speed improvement in binleave and binunleave. *UPDATE* ConfigObj Version 3.2.2 configobj.py and fullconfigobj.py - ultra simple config file reading and writing. Defined basestring for Python 2.2. (Thanks to Imre Andras Robert for uncovering this). *UPDATE* caseless Version 2.1.1 caseless.py - case insensitive dictionary, list and sort method. Defined sliceobj for versions of Python prior to 2.3 *NEW* in_test Version 1.0.0 in_test.py - view raw CGI POST data A simple test CGI that show several HTML forms and then displays the raw data posted to the CGI from the form. I created it for my own purposes - but someone else may find it useful to understand/view how the browser sends form data to a CGI. (Including file uploads). Online version at http://www.voidspace.xennos.com/index.html#in_test *REMINDER* Xennos Hosting Cheap web hosting including python 2.2 and mailman. Hosting packages from $1 a month. I've been with Xennos for nearly a year, on one of their cheaper packages, and am very pleased with the service. http://www.xennos.com Any of my Python CGIs (http://www.voidspace.xennos.com ) can be installed and used on a xennos account - great for creating/testing CGIs. (And no - I don't own any shares.... but it would be nice to see a few more python CGIs around - anyone fancy building a decent python forum CGI ?...) Regards, Fuzzy

Hello! Bookmarks Database and Internet Robot WHAT IS IT A set of classes, libraries, programs and plugins I use to manipulate my bookmarks.html. I like Mozilla, but I need more features. I want to extend Mozilla's "Check for updates" feature (Navigator4 called it "Update bookmarks"). WHAT'S NEW in version 3.4.0 (2004-09-23) Extended support for Mozilla; keywords in bookmarks. Updated to m_lib version 1.2. WHAT'S NEW in version 3.3.2 parse_html.py can now recode unicode entities in titles. WHAT'S NEW in version 3.3.0 Required Python 2.2. HTML parser. If the protocol is HTTP, and there is Content-Type header, and content type is text/html, the object is parsed to extract its title; if the Content-Type header has charset, or if the HTML has <META> with charset, the title is converted from the given charset to the default charset. The <HEADER> is also parsed to extract <META> tag with redirect, if any. WHAT'S NEW in version 3.0 Complete rewrite from scratch. Created mechanism for pluggable storage managers, writers (DB dumpers/exporters) and robots.

ANN: PyQt v3.13 Released
by Phil Thompson 23 Sep '04

23 Sep '04

Riverbank Computing is pleased to announce the release of PyQt v3.13 available from http://www.riverbankcomputing.co.uk/. Changes since the last release include support for the QUuid, QMetaObject and QMetaProperty classes. PyQt is a comprehensive set of Qt bindings for the Python programming language and supports the same platforms as Qt. Like Qt, PyQt is available under the GPL (for UNIX, Linux and MacOS/X), a commercial license (for Windows, UNIX, Linux and MacOS/X) and a free educational license (for Windows). PyQt is implemented as a set of 9 extension modules containing 300 classes and over 5,750 functions and methods. PyQt also includes bindings to QScintilla, the port to Qt of the Scintilla editor component. PyQt can be used either as a rapid prototyping tool, or as an alternative to C++ for developing large Qt applications. PyQt includes the pyuic utility which generates Python code to implement user interfaces created with Qt Designer in the same way that the uic utility generates C++ code. Third party tools are also available - such as eric3, a comprehensive IDE (including an editor, debugger, class browser, integration with Qt Designer, re-factoring tools, unit testing tools and integration with source code control systems). eric3 is written entirely using PyQt and is available from http://www.die-offenbachs.de/detlev/eric3.html.
