cx_Oracle 4.2
What is cx_Oracle? cx_Oracle is a Python extension module that allows access to Oracle and conforms to the Python database API 2.0 specifications with a few exceptions. Where do I get it? http://starship.python.net/crew/atuining What's new? 1) Added support for parsing an Oracle statement as requested by Patrick Blackwill. 2) Added support for BFILEs at the request of Matthew Cahn. 3) Added support for binding decimal.Decimal objects to cursors. 4) Added support for reading from NCLOBs as requested by Chris Dunscombe. 5) Added connection attributes encoding and nencoding which return the IANA character set name for the character set and national character set in use by the client. 6) Rework module initialization to use the techniques recommended by the Python documentation as one user was experiencing random segfaults due to the use of the module dictionary after the initialization was complete. 7) Removed support for the OPT_Threading attribute. Use the threaded keyword when creating connections and session pools instead. 8) Removed support for the OPT_NumbersAsStrings attribute. Use the numbersAsStrings attribute on cursors instead. 9) Use type long rather than type int in order to support long integers on 64-bit machines as reported by Uwe Hoffmann. 10) Add cursor attribute bindarraysize which is defaulted to 1 and is used to determine the size of the arrays created for bind variables. 11) Added repr() methods to provide something a little more useful than the standard type name and memory address. 12) Added keyword argument support to the functions that imply such in the documentation as requested by Harald Armin Massa. 13) Treat an empty dictionary passed through to cursor.execute() as keyword arguments the same as if no keyword arguments were specified at all, as requested by Fabien Grumelard. 14) Fixed memory leak when a LOB read would fail. 15) Set the LDFLAGS value in the environment rather than directly in the setup.py file in order to satisfy those who wish to enable the use of debugging symbols. 16) Use __DATE__ and __TIME__ to determine the date and time of the build rather than passing it through directly. 17) Use Oracle types and add casts to reduce warnings as requested by Amaury Forgeot d'Arc. 18) Fixed typo in error message. -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
ctypes 0.9.9.9 released
ctypes 0.9.9.9 released - July 21, 2006 === Overview ctypes is an advanced ffi (Foreign Function Interface) package for Python 2.3 and higher. ctypes allows to call functions exposed from dlls/shared libraries and has extensive facilities to create, access and manipulate simple and complicated C data types in Python - in other words: wrap libraries in pure Python. It is even possible to implement C callback functions in pure Python. ctypes runs on Windows, Windows CE, MacOS X, Linux, Solaris, FreeBSD, OpenBSD. It may also run on other systems, provided that libffi supports this platform. Changes in 0.9.9.9 Index checking on 1-sized arrays was reintroduced, so they can no longer be used as variable sized data. Assigning None to pointer type structure fields possible overwrote wrong fields. Fixed a segfault when ctypes.wintypes were imported on non-Windows machines. Accept any integer or long value in the ctypes.c_void_p constructor. It is now possible to use custom objects in the ctypes foreign function argtypes sequence as long as they provide a from_param method, no longer is it required that the object is a ctypes type. ctypes can now be built with MingW on Windows, but it will not catch access violations then since MingW does no structured exception handling. Sync the darwin/x86 port libffi with the copy in PyObjC. This fixes a number of bugs in that port. The most annoying ones were due to some subtle differences between the document ABI and the actual implementation :-( Release the GIL during COM method calls, to avoid deadlocks in Python coded COM objects. Changes in 0.9.9.7 Fixes for 64-bit big endian machines. It is now possible to read and write any index of pointer instances (up to 0.9.9.6, reading was allowed for any index, but writing only for index zero). Support for unnamed (anonymous) structure fields has been added, the field names must be listed in the '_anonymous_' class variable. Fields of unnamed structure fields can be accessed directly from the parent structure. Enabled darwin/x86 support for libffi (Bob Ippolito and Ronald Oussuren). Added support for variable sized data structures: array types with exactly 1 element don't do bounds checking any more, and a resize function can resize the internal memory buffer of ctypes instances. Fixed a bug with certain array or structure types that contained more than 256 elements. Changes in 0.9.9.6 The most important change is that the old way to load libraries has been restored: cdll.LoadLibrary(path), and CDLL(path) work again. For details see the changelog in CVS and in the source distribution. It was a mistake to change that in the 0.9.9.3 release - I apologize for any confusion and additional work this has caused or will cause. New module ctypes.util which contains a cross-platform find_library function. Sized integer types (c_int8, c_int16, and so on) have been added by integrating a patch from Joe Wreschnig. Also c_size_t, which corresonds to the 'size_t' C type has been added. Two long standing bugs with pointers have been fixed. Thanks to Axel Seibert for pushing me to the first, and thanks to Armin Rigo for finding the second one. The ctypes.decorator module has been removed completely, so the 'cdecl' and 'stdcall' symbols are no longer available. The code generator has been removed completely. It will probably be made available as a separate project later. The samples directory has been removed because it was completely out-of-date. The .zip and .tar.gz source distributions no longer contain different file sets. The development in CVS now takes place in the HEAD again, the 'branch_1_0' branch is no longer used. Changes in 0.9.9.3 Windows The ctypes.com package is no longer included and supported. It is replaced by the comtypes package which will be released separately. ctypes has been ported to Windows CE by Luke Dunstan. Other platforms Hye-Shik Chang has written a new build system for libffi which should remove possible licensing issues. All platforms The library loading code has been rewritten by Andreas Degert, there are now sophisticated methods to find shared libraries. On OS X, this uses files from Bob Ippolito's macholib. See the manual for details. Finally I started to write the manual, it is available online: http://tinyurl.com/7bpg4 New 'errcheck' protocol to check the return values of foreign functions, suggested by Mike Fletcher. Lots of bug fixes, especially for 64-bit platforms. Improved performance when
cx_Freeze 3.0.3
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 What's new? 1) In Common.c, used MAXPATHLEN defined in the Python OS independent include file rather than the PATH_MAX define which is OS dependent and is notavailable on IRIX as noted by Andrew Jones. 2) In the initscript ConsoleSetLibPath.py, added lines from initscript Console.py that should have been there since the only difference between that script and this one is the automatic re-execution of the executable. 3) Added an explicit import encodings to the initscripts in order to handle Unicode encodings a little better. Thanks to Ralf Schmitt for pointing out the problem and its solution. 4) Generated a meaningful name for the extension loader script so that it is clear which particular extension module is being loaded when an exception is being raised. 5) In MakeFrozenBases.py, use distutils to figure out a few more platform-dependent linker flags as suggested by Ralf Schmitt. -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
Ann: Crunchy Frog 0.6
Crunchy Frog (version 0.6) has been released. Crunchy Frog is an application that transforms an html-based Python tutorial into an interactive session within a browser window. The interactive embedded objects include: * a Python interpreter; * a simple code editor, whose input can be executed by Python; * a special doctest mode for the code editor; * a graphics canvas which can be drawn upon using a simple api. * simple sounds can be generated and played with all of the above. A comprehensive set of examples are included in the package, as well as two standard Python tutorials (mini-sorting HowTo, and regular expression HowTo) which have been adapted for use with Crunchy Frog. Requirements: Python 2.4+ (it might work, but has not been tested with earlier versions) Elementtree; (a link is provided in the included docs) Firefox 1.5+ The website address is http://crunchy.sourceforge.net The files can be downloaded from http://sourceforge.net/project/showfiles.php?group_id=169458 André and Johannes -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
Ophelia 0.1
The first release of Ophelia, 0.1, has just been tagged. From README.txt: = Ophelia creates XHTML pages from templates written in TAL, the Zope Template Attribute Language. It is designed to reduce code repetition to zero. At present, Ophelia contains a request handler for the Apache2 web server. Static content -- Consider Ophelia as SSI on drugs. It's not fundamentally different, just a lot friendlier and more capable. Use Ophelia for sites where you basically write your HTML yourself, except that you need write the recurring stuff only once. Reducing repetition to zero comes at a price: your site must follow a pattern for Ophelia to combine your templates the right way. Consider your site's layout to be hierarchical: there's a common look to all your pages, sections have certain characteristics, and each page has unique content. It's crucial to Ophelia that this hierarchy reflects in the file system organization of your documents; how templates are nested is deduced from their places in the hierarchy of directories. Dynamic content --- Ophelia makes the Python language available for including dynamic content. Each template file may include a Python script. Python scripts and templates contributing to a page share a common set of variables to modify and use. Ophelia's content model is very simple and works best if each content object you publish is its own view: the page it is represented on. If you get content from external resources anyway (e.g. a database or a version control repository), it's still OK to use Ophelia even with multiple views per content object as long as an object's views doesn't depend on the object's type or even the object itself. Trying to use Ophelia on a more complex site will lead to an ugly entanglement of logic and presentation. Don't use Ophelia for sites that are actually web interfaces to applications, content management systems and the like. = To use Ophelia, you need - Apache2 - Python 2.3 or better - mod_python 3.1 or better - the zope package from Zope3 Ophelia is released under the Zope Public License, version 2.1. You can access the source code repository at https://svn.thomas-lotze.de/repos/public/Ophelia/, browse it using ViewCVS at http://svn.thomas-lotze.de/svn-public/Ophelia/, and download the 0.1 release from http://svn.thomas-lotze.de/svn-public/Ophelia/tags/Ophelia-0.1.tar.gz. Ophelia is currently used to deliver its author's private web site. -- Thomas -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
