cx_OracleTools 7.3
by Anthony Tuininga 26 Jan '06

26 Jan '06

What is cx_OracleDBATools? cx_OracleTools is a set of Python scripts that handle Oracle database development tasks in a cross platform manner and improve (in my opinion) on the tools that are available by default in an Oracle client installation. Those who use cx_Oracle (a Python interface driver for Oracle compatible with the DB API) may also be interested in this project, if only as examples. Binaries are provided for those who do not have a Python installation. Where do I get it? http://starship.python.net/crew/atuining What's new? 1) Added ExportXML and ImportXML utilities for importing and exporting data from an Oracle database as XML. 2) Added support in ExportData for limiting the number of rows exported and skipping some rows first. 3) Added support in CopyData for the case where all the columns on the target table form the primary key. 4) Added support for case sensitive tables and column names in CopyData. 5) Added option --report-point to CopyData which defaults to --commit-point. 6) Added options --log-file, --log-level and --log-prefix to all of the tools and removed --timestamp and --prefix on DbDebugger since the new options cover the functionality of the old ones. 7) Added options --suppress-owner-dir, --include-roles, --include-users, --no-related and --no-triggers to ExportObjects. 8) Added option --sort-by to DumpData to modify the query executed to include a sort clause. 9) Added option --only-if to DescribeSchema and ExportObjects which allows for filtering the objects described by a where clause against dba_objects. 10) DbDebugger now displays the time to the microsecond if desired. 11) GeneratePatch now makes sure that owner changes are displayed before displaying anything about the objects for that owner that are being patched. 12) GeneratePatch now produces consistent results by performing a sort before displaying any results. 13) Fixed bug in GeneratePatch parsing grants with the "with grant option" specified. 14) Fixed bug in DescribeObject where connect statements were being displayed.

cx_OracleDBATools 2.1
by Anthony Tuininga 26 Jan '06

26 Jan '06

What is cx_OracleDBATools? cx_OracleDBATools is a set of Python scripts that handle Oracle DBA tasks in a cross platform manner. These scripts are intended to work the same way on all platforms and hide the complexities involved in managing Oracle databases, especially on Windows. Binaries are provided for those who do not have a Python installation. Where do I get it? http://starship.python.net/crew/atuining What's new? 1) Added support for Oracle 10g. 2) Enhanced CreateDB to treat all unknown keys in each database type section of the configuration file and additional parameters after the SID on the command line as user specified parameters that will be used when doing the substitution in the template init.ora, template creation sql, and the template directory files. 3) Enhanced ExportControlFile to include the current archive log mode so when the control file is recreated, it will be the same. 4) Enhanced BackupDB to allow lower level compression by adding the --compress option. 5) Enhanced RestoreDB to display information about a backup file without having to restore the database by adding the options --info (prints summary information) and --list (lists all files in the backup). 6) Enhanced RestoreDB to allow the changing of ORACLE_HOME when restoring a database as a different SID. 7) Enhanced StartDB to allow restarting the database if it is already started by adding the options --restart and --shutdown-mode. 8) Enhanced RestoreDB to remove an existing database if desired by adding the options --replace-existing, --tnsentry and --sys-password. 9) Added simple script which examines the memory maps on Linux to determine how much shared/private/mapped memory is in use. The output of this script is still less than useful for the shared and mapped memory. 10) Stopped backing up temporary files since they can be rebuilt faster upon restore. 11) Fixed the problem of backing up the same directory twice under file systems that are not case sensitive. 12) Fixed parsing of the log_archive_dest parameter. 13) Removed restriction on the new directory being different from the old one when performing a restore so that restoring to the same location on a different machine is possible. 14) Put password in quotes in the templates so that it does not have to follow Oracle naming conventions. 15) Added parameter db_cache_size as another size parameter. 16) Split the template OracleControl.ini into files for Windows and files for Unix type machines.

ANN: ActivePython 2.4.2.10 is now available
by Trent Mick 24 Jan '06

24 Jan '06

I'm happy to announce that ActivePython 2.4.2.10 is now available for free download from: http://www.ActiveState.com/Products/ActivePython/ This release is a maintenance/update release for existing platforms and adds support for three new ones: Mac OS X/x86, Windows/x64 and Linux/x86_64. See below for a full list of supported platforms. Changes in this release include: - Add early support for Mac OS X for Intel platform (macosx-x86). Please see the "Mac OS X for Intel" section below for details. - Upgrade to PyWin32 build 207 on Windows/x86 - Upgrade Tkinter to Tcl/Tk 8.4.12 - Support for Windows/x64 (win64-x64). Note that PyWin32 has not been ported to 64-bit Windows so this build does not include PyWin32. - Support for Linux/x86_64 (linux-x86_64) - Fixed a problem on Mac OS X/PowerPC that unintentionally created a dependency on Fink (fink.sourceforge.net) for the "bz2" and "curses" extensions. (Thanks, Bob!) - The Windows "debug libraries" package now allows installation into non-ActivePython Python installations of the same version. This was requested by Dave Abrahams for the Boost folks (http://tinyurl.com/898zw). - Changed Intel 32-bit architecture platform name from "ix86" to "x86", changing package names for some ActivePython builds. Mac OS X for Intel ------------------ This is the first release of ActivePython for Mac OS X/Intel. It should be considered an early release. This build is not a universal build and there are a number of known issues: http://aspn.activestate.com/ASPN/docs/ActivePython/2.4/relnotes.html#KI_mac… I suspect that ultimately a universal Python build is the right answer, but details and issues around that should be discussed on the Python Mac mailing list: pythonmac-sig(a)python.org What is ActivePython? --------------------- ActivePython is ActiveState's quality-assured binary distribution of Python. Builds for AIX, HP-UX, Linux, Mac OS X, Solaris, and Windows are made freely available. ActivePython includes the Python core and core extensions (zlib 1.2.3, bzip2 1.0.2, bsddb 4.2.52, Tk 8.4.12, and Tix 8.1.4) and is fully compatible with other Python distributions of the same version. ActivePython also includes a wealth of Python documentation, including: - the core Python docs; - Andrew Kuchling's "What's New in Python" series; - the Non-Programmer's Tutorial for Python; - Mark Pilgrim's excellent "Dive into Python"; and - a snapshot of the Python FAQs, HOWTOs, and PEPs. An online version of the docs can be found here: http://aspn.activestate.com/ASPN/docs/ActivePython/2.4/welcome.html We would welcome any and all feedback to: ActivePython-feedback(a)ActiveState.com Please file bugs against ActivePython at: http://bugs.ActiveState.com/ActivePython On what platforms does ActivePython run? ---------------------------------------- ActivePython now includes installers for the following ten platforms: - AIX/PowerPC - HP-UX/PA-RISC - Linux/x86 - (new) Linux/x86_64: "x86_64" is also known as "AMD64" - Solaris/SPARC - Solaris/x86 - Mac OS X/PowerPC - (new) Mac OS X/x86: - (new) Windows/x64: "x64" is also known as "AMD64" - Windows/x86 Extra Bits ---------- ActivePython releases also include the following packages: - Windows "debug" package: Debug-built binaries for ActivePython users building debug versions of their binary Python extensions. - ActivePython24.chm: An MS compiled help collection of the full ActivePython documentation set. Linux users of applications such as xCHM might find this useful. This package is installed by default on Windows.

ANN: PyVISA 1.0 -- GPIB, USB, RS232 instrument control
by Torsten Bronger 24 Jan '06

24 Jan '06

Hallöchen! At http://pyvisa.sourceforge.net you can find information about the PyVISA package. It realises Python bindings for the VISA library functions, which enables you to control GPIB, USB, and RS232-serial measurement devices via Python. Today I released version 1.0. If you have v0.9.7 of last september already, you needn't download it because it contains only minor improvements in the documentation. However, since I've received a couple of positive reports about successful use of PyVISA (and no negatives), I finally dare to jump to 1.0 and declare it stable. Tschö, Torsten.

IPython 0.7.1 is out.
by Fernando Perez 24 Jan '06

24 Jan '06

Hi all, I have released IPython 0.7.1, which is mainly a bugfix release over 0.7.0. As expected in that release, given the large changes made, some problems inevitably appeared. I believe all regressions and known bugs have been fixed, along with some useful new features. This release marks the end of my tenure on the stable branch of ipython. Ville Vainio will continue as maintainer of the ipython trunk/, while I will continue working on the development branch of IPython (chainsaw). I will remain available on the list as usual, both to assist Ville as needed, and to discuss withe anyone interested. But I'll try to limit my time and effort spent on trunk to a minimum, so we can really advance the (fairly ambitious) chainsaw project. WHAT is IPython? ---------------- 1. An interactive shell superior to Python's default. IPython has many features for object introspection, system shell access, and its own special command system for adding functionality when working interactively. 2. An embeddable, ready to use interpreter for your own programs. IPython can be started with a single call from inside another program, providing access to the current namespace. 3. A flexible framework which can be used as the base environment for other systems with Python as the underlying language. 4. A shell for interactive usage of threaded graphical toolkits. IPython has support for interactive, non-blocking control of GTK, Qt and WX applications via special threading flags. The normal Python shell can only do this for Tkinter applications. Where to get it --------------- IPython's homepage is at: http://ipython.scipy.org and downloads are at: http://ipython.scipy.org/dist I've provided: - source downloads (.tar.gz) - RPMs (for Python 2.3 and 2.4, built under Fedora Core 3). - Python Eggs (http://peak.telecommunity.com/DevCenter/PythonEggs). - a native win32 installer for both Python 2.3 and 2.4. Fedora users should note that IPython is now officially part of the Extras repository, so they can get the update from there as well (though it may lag by a few days). Debian, Fink and BSD packages for this version should be coming soon, as the respective maintainers have the time to follow their packaging procedures. Many thanks to Jack Moffit, Norbert Tretkowski, Andrea Riciputi and Dryice Liu). The eggs included now are lighter, as they don't include documentation and other ancillary data. If you want a full ipython installation, use the source tarball or your distribution's favorite system. Many thanks to Enthought for their continued hosting support for IPython. Release notes ------------- As always, the full ChangeLog is at http://ipython.scipy.org/ChangeLog. The highlights of this release follow. - *FIXED: this wasn't really working right in 0.7.0* Support for input with empty lines. If you have auto-indent on, this means that you need to either hit enter _twice_, or add/remove a space to your last blank line, to indicate you're done entering input. These changes also allow us to provide copy/paste of code with blank lines. - *FIXED: this wasn't really working right in 0.7.0* Support for pasting multiline input even with autoindent on. The code will look wrong on screen, but it will be stored and executed correctly internally. Note that if you have blank lines in your code, these need to be indented like their surroundings (pure empty lines will make ipython assume you are finished with your input). This is a limitation also of the plain python interpreter, and can't really be fixed in a line-oriented system like ipython. - Fixed bug where macros were not working correctly in threaded shells. - Catch exceptions which can be triggered asynchronously by signal handlers. This fixes a rare and obscure problem, but which could crash ipython; reported by Colin Kingsley <tercel-AT-gentoo.org>. - Added new '-r' option to %hist, to see the raw input history (without conversions like %ls -> ipmagic("ls")). - Fix problems with GTK under win32 (excessive keyboard lag and cpu usage). - Added ipython.py script to root directory of download. This allows you to unpack ipython and execute it in-place, without needing to install it at all. - Improved handling of backslashes (\) in magics. This improves the usability of ipython especially under win32, which uses \ as a path separator (though it also benefits Unix for escaping characters in shell usage). - More autocall fixes (rare, but critical). - New IPython.ipapi module to begin exposing 'officially' IPython's public API. This should ease the task of those building systems on top of ipython. - New IPython.platutils module, exposing various platform-dependent utilities (such as terminal title control). - Implemented exception-based 'chain of command' for IPython's hooks. - Added Jason Orendorff's "path" module to IPython tree, http://www.jorendorff.com/articles/python/path/. You can get path objects conveniently through %sc, and !!, e.g.: sc files=ls for p in files.paths: # or files.p print p,p.mtime - Fix '%run -d' with Python 2.4 (pdb changed in Python 2.4). - Various other small fixes and enhancements. Enjoy, and as usual please report any problems. Regards, and thanks for all this time using IPython! Fernando.

PyWeek Challenge #2: write a game in a week
by Richard Jones 24 Jan '06

24 Jan '06

The date for the second PyWeek challenge has been set: Sunday 26th March to Sunday 2nd April (00:00UTC to 00:00UTC). The PyWeek challenge invites entrants to write a game in one week from scratch either as an individual or in a team. Entries must be developed in Python, during the challenge, and must incorporate some theme chosen at the start of the challenge. REGISTRATION IS NOT YET OPEN -- In order to reduce the number of unnecessary registrations, we will open the challenge for registration one month before the start date. See the competition timetable and rules at: http://www.pyweek.org/ PLANNING FOR THE CHALLENGE -- Make sure you have working versions of the libraries you're going to use. The rules page has a list of libraries and other resources. Make sure you can build packages to submit as your final submission (if you're going to use py2exe, make sure you know how to use it and that it works). If you don't have access to Linux, Windows or a Mac to test on, contact friends, family or other competitors to find someone who is able to test for you.

Myghty 1.0 Released
by Michael Bayer 23 Jan '06

23 Jan '06

Myghty 1.0 Released Myghty is a Python Server Page templating and web framework designed for large-scale, high availability websites and applications. Its conceptual design and template syntax is derived from HTML::Mason, the widely used mod_perl web application platform. Myghty serves as an excellent platform for developers to create custom web applications, as well as a base framework for webstacks (pre-architected web framework/persistence framework packages). Since its original release, Myghty has introduced many new concepts and features not found in Mason, including a rudimentary MVC framework, WSGI support, threading support and an open-ended rule-based URL resolution system. It receives favorable reviews for its ease of use, small footprint, quick and smooth operation, and great flexibility. Myghty is now embeddable in a large range of Python frameworks, including mod_python, Python Paste, generic WSGI applications, CherryPy, and Turbogears, and is the core template and controller system for the upcoming Pylons web framework. Version 1.0 introduces a license change to the MIT License, as well as some small feature releases, improved documentation and inline code docs, and a tweak here or there to support Pylons. It also represents a stabilization of all the features that have been developed thus far, including caching/session support with Memcached, rule-based resolver configuration, basic support for Python Paste, and the Module Components view/controller framework. Myghty is released under the MIT License. Documentation, examples and download links can be found at: http://www.myghty.org Michael Bayer mike(a)myghty.org <P><A HREF="http://www.myghty.org">Myghty 1.0</A> - A high performance Python Server Page templating framework derived from HTML::Mason.

rencode -- Reduced length encodings
by Connelly Barnes 23 Jan '06

23 Jan '06

A space-efficient serialization module based on bencode, which can be used to decode strings from untrusted sources. Works well for complex, heterogeneous data structures with many small elements. The encodings take considerably less space than bencode, gherkin, and Recipe 415503 for that use case, and this module is faster, too. Source (MIT license) is available from: http://barnesc.blogspot.com/2006/01/ rencode-reduced-length-encodings.html --------------------------------------------------------------------- Comparison of rencode with similar modules --------------------------------------------------------------------- Connelly Barnes, 2006-01-23. The following data structures were used: Case 1: range(100) Case 2: range(10000) Case 3: {192: [3.3492934923942394, 1.230030343242342, 9.4929349232349243, 9.4939349349394931, 4.342992349295949, 0.4309953949239393], 298: [6.3249093409490905, 2.439009234090990, 0.9139904909090434, 5.8795437823407908, 3.529098080909880, 4.5899843289893433]} All modules were modified to use 64-bit float encoding. Case 4: {'abc': 'abc0123', 'def': 'def0123', 'ghi': 'ghi0123', '0123456789': '0123456789'} Case 5: ' '*10000 --------------------------------------------------------------------- Results --------------------------------------------------------------------- The four modules rencode, bencode, gherkin and Recipe 415503 were used to encode each of the preceding data structures. The size of the encoded string and the number of calls per second to the encoding function (on a Windows 3.0 GHz Intel machine) are summarized: rencode bencode gherkin recipe Case 1: 170 392 511 505 bytes 19315.318 10002.625 6080.862 5170.539 calls/sec Case 2: 29842 58892 50011 50005 bytes 148.454 88.767 59.236 52.619 calls/sec Case 3: 117 N/A 149 143 bytes 51254.721 N/A 15470.597 17869.132 calls/sec Case 4: 59 70 121 115 bytes 118209.471 64589.227 20216.850 22516.589 calls/sec Case 5: 10006 10006 10011 10005 bytes 100186.770 100663.271 75245.603 102635.125 calls/sec The source code used to build this table is available at: http://oregonstate.edu/~barnesc/python/rencode_compare.py __________________________________________________ Do You Yahoo!?
