ANN: cssutils 0.9.7b1
by Christof 30 May '10

30 May '10

what is it ---------- A Python package to parse and build CSS Cascading Style Sheets. (Not a renderer though!) about this release ------------------ 0.9.7b1 is a beta release but quite stable now I guess... main changes ------------ 0.9.7b1 optimizes handling speed of CSSVariables *a lot*... changes + **API CHANGE**: Child objects like the ``cssRules`` of a ``CSSStyleSheet`` or ``CSSMediaRule`` are no longer kept after resetting the complete contents of an object (setting ``cssText``). This should not be expected anyway but if you relied on something like the following please beware:: sheet = cssutils.parseString('a { color: red}') initial_rules = sheet.cssRules sheet.cssText = 'b { color: green}' # true until 0.9.6a6: assert sheet.cssRules == initial_rules, but now: assert sheet.cssRules != initial_rules + **IMPROVEMENT**: Massive speed improvement of handling of CSSVariables of a stylesheet which due to naive implementation was unbelievable slow when using a lot of vars... Should now scale a lot better, about factor 5-20 depending of amount of variables used. + IMPROVEMENT: Fair amount of refactoring resulting in a bit speed improvement generally too + CHANGE: If a CSS variable should be resolved (``cssutils.ser.prefs.resolveVariables == true``) but no value can be found a WARNING is logged now. Should be an ERROR actually but as currently lots of "fake" errors are reported would probably hurt more than help. A future release might improve this. + BUGFIX: Syntax of value of CSS Fonts Module Level 3 ``src`` property now validates if local font name is given with a quoted name, e.g.: ``src: local('Yanone Kaffeesatz')`` license ------- cssutils is published under the LGPL version 3 or later, see http://cthedot.de/cssutils/ If you have other licensing needs please let me know. download -------- For download options see http://cthedot.de/cssutils/ cssutils needs Python 2.4 or higher or Jython 2.5 and higher (tested with Python 2.6.5(x64), 2.5.4(x32), 2.4.4(x32) and Jython 2.5.1 on Win7 64 only) Bug reports (via Google code), comments, etc are very much appreciated! Thanks. Christof

ANN: esky 0.7.0
by Ryan Kelly 28 May '10

28 May '10

Hi All, I'm pleased to announce the latest release of esky, an auto-update framework for frozen python apps. New features include: * ability to escalate to root privileges when necessary * better safety guarantees on Windows XP and lower * better support for py2exe with different bundle_files options More details below for those who are interested. Cheers, Ryan ------------------------------- esky: keep frozen apps fresh Esky is an auto-update framework for frozen Python applications. It provides a simple API through which apps can find, fetch and install updates, and a bootstrapping mechanism that keeps the app safe in the face of failed or partial updates. Esky is currently capable of freezing apps with bbfreeze, cxfreeze, py2exe and py2app. The latest version is v0.7.0, with the following major changes: * Renamed "esky.helper" to "esky.sudo" along with much refactoring: * @esky.use_helper_app is now @esky.allow_from_sudo() and is used to declare a type signature. * Esky.helper_app is now Esky.sudo_proxy and is always an instance of esky.sudo.SudoProxy. * added Esky.drop_root() method to drop root privileges. * implemented multiple safeguards against malicious input when running with root privileges. * Cause all scripts to automagically call esky.run_startup_hooks() on startup. Currently this: * detects the --esky-spawn-sudo option, runs sudo helper. * detects the --esky-spawn-cleanup option, runs cleanup helper. * Have Esky.auto_update() call Esky.cleanup() automatically (mostly so it can immediately drop any root privileges it has acquired). * Use a separate file "esky-lockfile.txt" for version locking. This will help protect against strange behaviour when fcntl.flock is simulated using fcntl.lockf (which released the lock when *any* handle to the file is closed). * Try to load correctly if executed from a temporary backup file (e.g. running from "prog.old.exe" instead of "prog.exe"). * Allow direct overwriting of existing bootstrap files on win32 (instead of renaming the old version out of the way) but only in very special circumstances: * currently only for executables where the icon or version info has changed but the rest of the exe has not. * may require spawning a new copy of the process at shutdown, to overwrite any in-use bootstrap exes (use Esky.cleanup_at_exit) * Several improvements to py2exe support: * implemented "optimize" and "unbuffered" settings in the custom bootstrap code. * more robust support for the various bundle_files options.

PyUseCase 3.3 : GUI testing for PyGTK and Tkinter
by Geoff Bache 27 May '10

27 May '10

Hi all, Tkinter support has matured a fair amount with support added for three new widget types (Canvas, Checkbutton and Listbox). There has also been work done on the PyGTK side with a couple of new widget types supported (TextView, SpinButton) and quite a few bugfixes. See ChangeLog in the download for full details. Regards, Geoff Bache A bit more detail: PyUseCase is an unconventional GUI testing tool for PyGTK and Tkinter, along with a framework for testing Python GUIs in general. Instead of recording GUI mechanics directly, it asks the user for descriptive names and hence builds up a "domain language" along with a "UI map file" that translates this language into actions on the current GUI widgets. The point is to reduce coupling, allow very expressive tests, and ensure that GUI changes mean changing the UI map file but not all the tests. Instead of an "assertion" mechanism, it auto-generates a log of the GUI appearance and changes to it. The point is then to use that as a baseline for text-based testing, using e.g. TextTest. It also includes support for instrumenting code so that "waits" can be recorded, making it far easier for a tester to record correctly synchronized tests without having to explicitly plan for this.

asciitable 0.2.4: an extensible ASCII table reader
by Tald 27 May '10

27 May '10

I'm pleased to announce the release of version 0.2.4 of the asciitable module. Please see the project home page or PyPI for download and documentation: http://cxc.harvard.edu/contrib/asciitable/ At the top level asciitable looks like many other ASCII table readers since it provides a default read() function with a long list of parameters to accommodate the many variations possible in commonly encountered ASCII table formats. But unlike other monolithic table reader implementations, asciitable is based on a modular and extensible class structure. Formats that cannot be handled by the existing hooks in the read() function can be accomodated by modifying the underlying class methods as needed. Asciitable can read a wide range of ASCII table formats via built-in Extension Reader Classes (derived from base class elements): * Basic: basic table with customizable delimiters and header configurations * Cds: CDS format table (also Vizier and ApJ machine readable tables) * CommentedHeader: column names given in a line that begins with the comment character * Daophot: table from the IRAF DAOphot package * Ipac: IPAC format table * NoHeader: basic table with no header where columns are auto-named * Rdb: tab-separated values with an extra line after the column definition line * Tab: tab-separated values Copyright: Smithsonian Astrophysical Observatory (2010) Author: Tom Aldcroft (aldcroft(a)head.cfa.harvard.edu) License: BSD (3-clause)

StarCluster 0.91 Released - Scientific Computing on Amazon EC2
by Justin Riley 27 May '10

27 May '10

Hi All, The next version, 0.91, of StarCluster (http://web.mit.edu/starcluster) has been released. StarCluster is a utility for creating and managing scientific computing clusters hosted on Amazon's Elastic Compute Cloud (EC2). StarCluster utilizes Amazon's EC2 web service to create and destroy clusters of Linux virtual machines on demand. New in this version: -------------------- * support for launching and managing multiple clusters on EC2 * added "listclusters" command for showing all active clusters on EC2 * support for attaching and NFS-sharing multiple EBS volumes * added createimage and createvolume commands for easily creating new AMIs and EBS volumes for use with StarCluster * experimental support for launching clusters using spot instances * added support for StarCluster "plugins" that provide the ability to perform additional configuration/setup routines on top of StarCluster's default cluster configuration * added "listpublic" command for listing all available public StarCluser AMIs that can be used with StarCluster * bash/zsh command line completion for StarCluster's command line interface Download -------- StarCluster is available on PyPI (http://pypi.python.org/pypi/StarCluster) and also on the website: http://web.mit.edu/starcluster You will find the docs as well as links to the StarCluster mailing list on the website. Learn More ------------- For those that are interested in learning more there is an article about StarCluster on www.hpcinthecloud.com http://www.hpcinthecloud.com/features/StarCluster-Brings-HPC-to-the-Amazon-… There is also a screencast of installing, configuring, launching, and terminating an HPC cluster on Amazon EC2: http://www.hpcinthecloud.com/blogs/MITs-StarCluster-An-Update-with-Screenca… StarCluster Description (From PYPI): StarCluster is a utility for creating and managing computing clusters hosted on Amazon's Elastic Compute Cloud (EC2). StarCluster utilizes Amazon's EC2 web service to create and destroy clusters of Linux virtual machines configured for scientific computing on demand. To get started, the user creates a simple configuration file with their AWS account details and a few cluster preferences (e.g. number of machines, machine type, ssh keypairs, etc). After creating the configuration file and running StarCluster's "start" command, a cluster of Linux machines configured with the Sun Grid Engine queuing system, an NFS-shared /home directory, and OpenMPI with password-less ssh is created and ready to go out-of-the-box. Running StarCluster's "stop" command will shutdown the cluster and stop paying for service. This allows the user to only pay for what they use. StarCluster can also utilize Amazon's Elastic Block Storage (EBS) volumes to provide persistent data storage for a cluster. EBS volumes allow you to store large amounts of data in the Amazon cloud and are also easy to back-up and replicate in the cloud. StarCluster will mount and NFS-share any volumes specified in the config. StarCluster's "createvolume" command provides the ability to automatically create, format, and partition new EBS volumes for use with StarCluster. StarCluster provides a Ubuntu-based Amazon Machine Image (AMI) in 32bit and 64bit architectures. The AMI contains an optimized NumPy/SciPy/Atlas/Blas/Lapack installation compiled for the larger Amazon EC2 instance types. The AMI also comes with Sun Grid Engine (SGE) and OpenMPI compiled with SGE support. The public AMI can easily be customized by launching a single instance of the public AMI, installing additional software on the instance, and then using StarCluster's "createimage" command to completely automate the process of creating a new AMI from an EC2 instance.
