Scratchy 0.5 - Report Generator and Log Parser for Apache access logs
by stuff＠nonpoint.mailzilla.net June 30, 2003

June 30, 2003

http://scratchy.sourceforge.net Features new to this version: * bar charts will be produced (requires gdchart module. See Docs on Scratchy website for more information) * a main summary page is now created for easier navigation * some bug fixes About Scratchy Scratchy is a set of scripts to parse Apache web server log files and extract useful information. From this data, Scratchy will create HTML reports so that website administrators can easily view the information and determine trends and their typical audience. Scratchy began as a proof-of-concept which allowed me to compile stats about my personal website. As time progressed I continually added features and improvements and I felt that it was now at a point that it would be useful to others. Why Scratchy? Well, the name of the project of course comes from the Simpsons "Itchy and Scratchy Show". The functionality that the project aims to supply is a complete log parsing and report generating tool. Also, there seemed to be a need for such a project in Python. I have seen some other Apache log parsers but they were developed in other languages (such as Perl, C, etc). One goal of this project is for it to be extensible, to that tune, most of the report appearance can be easily modified by tweaking a single config file. What information does Scratchy report? # Accessed web pages # hosts accessing your website # operating systems # browsers # search engines # robots # file types accessed # errors # a trace of pages accessed by each ip address (if enabled). http://scratchy.sourceforge.net

ANN: pyUnRAR 0.1
by Jimmy Retzlaff June 30, 2003

June 30, 2003

pyUnRAR is a ctypes based wrapper around the free UnRAR.dll. It enables reading and unpacking of archives created with the RAR/WinRAR archivers. There is a low-level interface which is very similar to the C interface provided by UnRAR.dll. There is also a high-level interface which makes some common operations easier. pyUnRAR requires Microsoft Windows, Python 2.2 or higher, and ctypes 0.6.2. pyUnRAR is available at: http://www.averdevelopment.com/python/ This is the initial public release of pyUnRAR. I'd appreciate any feedback. Jimmy

ANN: dnspython 1.0.0
by Bob Halley June 30, 2003

June 30, 2003

dnspython 1.0.0, the first non-development version of dnspython, has been released. Here's the README file: dnspython INTRODUCTION dnspython is a DNS toolkit for Python. It supports almost all record types. It can be used for queries, zone transfers, and dynamic updates. It supports TSIG authenticated messages and EDNS0. dnspython provides both high and low level access to DNS. The high level classes perform queries for data of a given name, type, and class, and return an answer set. The low level classes allow direct manipulation of DNS zones, messages, names, and records. To see a few of the ways dnspython can be used, look in the examples/ directory. dnspython originated at Nominum where it was developed to facilitate the testing of DNS software. Nominum has generously allowed it to be open sourced under a BSD-style license, and helps support its future development by continuing to employ the author :). ABOUT THIS RELEASE This is dnspython 1.0.0, the first non-development version of dnspython. New in this release: The Name and Rdata classes now use rich comparisons. If a resolver's cache attribute is set to an instance of dns.resolver.Cache, the resolver will cache an answer for the DNS lifetime of the answer. dns.resolver.Answer instances now have an "expiration" attribute. This release fixes all known bugs from 1.0.0b3. See the ChangeLog file for more detailed information on changes since the prior release. REQUIREMENTS Python 2.2 or later. INSTALLATION To build and install dnspython, type python setup.py install HOME PAGE For the latest in releases, documentation, and information, visit the dnspython home page at http://www.dnspython.org/ DOCUMENTATION Documentation is sparse at the moment.

RELEASED: Python 2.3b2
by Barry Warsaw June 30, 2003

June 30, 2003

Python 2.3b2 is the second beta release of Python 2.3. There have be a slew of fixes since the first beta, and a few new "features". Our goal is to have a final Python 2.3 release by early August, so we encourage lots of testing for this beta. Highlights since beta 1 include: - IDLEfork has been merged in and now replaces the old IDLE. - The Windows installer now ships with Tcl/Tk 8.4.3. - list.index() has grown optional `start' and `end' arguments. - A new C-only API function PyThreadState_SetAsyncExc() which can be used to interrupt threads by sending them exceptions. - Python programs can enter the interactive prompt at program exit by setting the PYTHONINSPECT environment variable. - Many new doctest improvements, including the ability to write doctest based unit tests. - New and improved documentation for writing new types in C that participate in cyclic garbage collection. There is at least one known bug: we have seen crashes on both Windows and Linux with certain interactions between test_logging and test_bsddb3. We intend to fix this for the next release. For more highlights, see http://www.python.org/2.3/highlights.html Other new stuff since Python 2.2: - Many new and improved library modules, e.g. sets, heapq, datetime, textwrap, optparse, logging, bsddb, bz2, tarfile, ossaudiodev, and a new random number generator based on the highly acclaimed Mersenne Twister algorithm (with a period of 2**19937-1!). - New builtin enumerate(): an iterator yielding (index, item) pairs. - Extended slices, e.g. "hello"[::-1] returns "olleh". - Universal newlines mode for reading files (converts \r, \n and \r\n all into \n). - Source code encoding declarations. (PEP 263) - Import from zip files. (PEP 273 and PEP 302) - FutureWarning issued for "unsigned" operations on ints. (PEP 237) - Faster list.sort() is now stable. - Unicode filenames on Windows. - Karatsuba long multiplication (running time O(N**1.58) instead of O(N**2)). If you have an important Python application, we strongly recommend that you try it out with a beta release and report any incompatibilities or other problems you may encounter, so that they can be fixed before the final release. To report problems, use the SourceForge bug tracker: http://sourceforge.net/tracker/?group_id=5470&atid=105470 Enjoy, -Barry

by Gregarius June 29, 2003

June 29, 2003

Pyrex 0.8.1 is now available: http://www.cosc.canterbury.ac.nz/~greg/python/Pyrex/ This release fixes some breakage in 0.8 that resulted in mangled names being used for some declarations in external header files. The distutils extension has also been modified slightly to stop it from attempting to compile the generated C file if the Pyrex compiler reports errors. What is Pyrex? -------------- Pyrex is a new language for writing Python extension modules. It lets you freely mix operations on Python and C data, with all Python reference counting and error checking handled automatically.

ctypes 0.6.2 released
by Thomas Heller June 26, 2003

June 26, 2003

Overview ctypes is a ffi (Foreign Function Interface) package for Python. It allows to call functions exposed from dlls/shared libraries and has extensive facilities to create, access and manipulate simple and complicated C data types transparently from Python - in other words: wrap libraries in pure Python. ctypes runs on Windows, MacOS X, Linux, Solaris, the latter three require that your machine is supported by libffi. On Windows, ctypes contains (the beginning of) a COM framework mainly targetted to use and implement custom COM interfaces. Changes in version 0.6.2 Fixed a bug which prevented callback functions to return data types other than integers. They can now also return pointers, floats, and doubles. It is now possible to pass structures and unions to function calls *by value*. Currently this works only on Windows. A lot of changes to the COM package, but all this is still work in progress and unstable, and it has to be properly documented.
