Spambayes 1.0a3 Released
by Meyer, Tony 22 Jun '03

22 Jun '03

The (very!) long awaited third spambayes pre-release is now available. This includes significant improvements over the previous release, and is recommended for all users. Note that this is not a new binary release for the Outlook plugin, which will be released soon. This release includes the following versions of the various Spambayes applications: o SMTP Proxy: SpamBayes SMTP Proxy Alpha1, version 0.01 (May 2003) o POP3 Proxy: SpamBayes POP3 Proxy Beta1, version 0.1 (May 2003), using SpamBayes POP3 Proxy Web Interface Alpha2, version 0.02 o Lotus Notes Filter: SpamBayes Lotus Notes Filter Alpha1, version 0.01 (March 2003) o IMAP Filter: SpamBayes IMAP Filter Alpha1, version 0.01 (May 2003), using SpamBayes IMAP Filter Web Interface Alpha1, version 0.01 o Outlook: SpamBayes Outlook Addin Beta1, version 0.3 (June 2003) [But see above] o Hammie: SpamBayes command line tool (Hammie) Beta1, version 0.1 (January 2003) The major changes from the previous release are listed below. For more details, the reader is referred to the changelog, or for extreme details, to the check-ins archive. This is a rather long list, since it has been a long time since the previous release. Changes are broken into sections for each application, plus one that will probably only interest developers, and one for everything else. Any actions necessary to move to this release from the previous release are noted in the "Transition" section. New in Alpha Release 3 ====================== Outlook Plugin -------------- o The Outlook Plugin now works with bsddb[3] databases, and uses them rather than pickles, if available. o The Outlook Plugin now stores files in the "correct" windows directory. These will be automatically migrated. o Show all tokens in message when showing clues in Outlook plugin. o Fix a bug in the Outlook plugin test code. o Only create "Spam" field on mail items in Outlook plugin. o MAPI exceptions are better handled. o Errors when hotmail connector cannot save the message are suppressed. o Tokens are listed one per line in Show Clues. o Messages can be scored after training. o Plugin *may* now work correctly in non-English locales. o Databases are saved after any training operation. o Handle malformed messages better in the Outlook plugin. o In Outlook plugin, create our own toolbar, rather than using the standard one. o Use 'wait' cursor when incremental training in Outlook plugin. o In Outlook plugin, save config when dialog closes and not at shutdown. o Clean up toolbar images. o In Outlook plugin, no longer default to the "Inbox". o In Outlook plugin, when filtering, saving the spam score is no longer fatal. o 2 new [General] options - delete_as_spam_message_state and recover_from_spam_message_state. o Prevent "Deleted items", Outbox and Sent Items from appearing in the folder list. o Allow either spam or unsure messages to be marked as read as they are filtered. o Significant improvements to the toolbar. o Standardised name from "Anti-Spam" to "Spambayes" o Significant changes to configuration (moving from a pickle to .ini files). POP3 Proxy ---------- o The POP3 Proxy can now include the classification in the "To" or "Subject" headers, which allows Outlook Express users to perform filtering on the classification. o The POP3 Proxy can add an id (as a header or in the body) to track emails. This can be used with the SMTP Proxy, or to find a particular message from the web interface. o Added include_score option to (optionally) note the score of the message in a header. o Added level (thermostat) and evidence headers for pop3proxy. o Added pop3proxy_server to allow pop3proxy to run as a Windows service. o Improved configuration page for the user interface. o A "Show Clues" button next to each message in the "Review" page of the web interface. o Messages in the "unknown" cache are expired, just like those in the "ham" and "spam" caches. o Messages are expired (if old enough) each time a client connects to the proxy, rather than on the proxy startup. o pop3proxy_port, pop3proxy_server_name and pop3proxy_server_port options were removed (these were deprecated in Alpha 2). o If a file is removed from the cache (not by the proxy) this no longer causes an exception. o Messages received in quick succession (within the same second) may not have been visible in the "review" page; fixed this. o Added "Refresh" button to "Review" page. o Improved proxying of "STAT" POP3 command so that a guess at the message size is returned. o Web interface encourage browsers not to cache the pages. o Added an option to display who a message is to in the "Review" page. o A new option to correct for a much higher ratio of spam to ham (or vice-versa) is available via the interface page. Developer --------- o Added base message classes for use by all Spambayes applications - currently used by the IMAP filter and POP3 proxy. o Major rework of the configuration file loading and format of Options.py. o Test code moved out of pop3proxy.py. o Web interface code abstracted out of pop3proxy.py. o A version information repository for all applications. General ------- o A utility to dump the contents of a CDB database. o -c and -d options to mailsort.py o A basic filter for Lotus Notes. o A SMTP Proxy to allow training via forwarding/bouncing messages. o Various files to test "incremental training" (or "self training"). o Option to mkgraph to spit out counts *or* error rates, and n-day averages *or* cumulative. o Note when the subject charset is invalid (rather than raising an exception). o A filter for IMAP. o A script to test the effectiveness of following URLs in messages when insufficient clues are otherwise present. o 'Nonsense' HTML tags are stripped rather than replaced with a space (e.g. Wr<!$FS|i|R3$s80sA >inkle Reduc<!$FS|i|R3$s80sA >tion becomes "Wrinkle" and "Reduction" rather than "Wr", "inkle", "Reduc" and "tion"). o Decode numeric character entities so that your se<!XE>ptic system becomes "your septic system". o <p> and <br> tags are replaced with single blanks. o DB classifier keeps a list of "changed words" to prevent saves from updating *all* words. o DB classifier no longer caches hapaxes. o In muttrc, fix incorrect Spambayes header name. o Integrated code for the VM mailer into spambayes.el o In hammiefilter, make untrain mode work. Transition ========== o If you are using the Outlook Plugin and a recent bsddb or bsddb3 is available, you will need to do a full retrain. o If you had set the environment variable BAYESCUSTOMIZE to point to more than one configuration file, you will need to change the separator character from a space to the path separator for your platform (a semi-colon on windows, a colon on *nix and a newline on Mac OS9) o If your old configuration file used the pop3proxy_port, pop3proxy_server_name or pop3proxy_server_port options, these will no longer work. Copy the values in them and use the web interface to update your configuration file. o Your old configuration file more than likely includes deprecated settings. The old settings will still work for the moment, but you should take the time to update them. The "convert_config_file.py" script will convert the file for you, without loss of comments, and avoiding whitespace changes where possible. o If you are using POP3 proxy, you should use the web interface to set the location of the "message info" database (a full pathname is recommended). o If you are using POP3 proxy, it is recommended (but not required) that you do a full retrain to take advantage of the "message info" database. Reported Bugs Fixed =================== The following bugs tracked via the Sourceforge system were fixed: 677804, 642740, 685746, 693423, 696995, 696476, 697120, 698852, 700165, 704921, 707491, 725307, 725616, 725307, 725466, 726255, 728886, 715248, 733247, 737956, 737955, 706170, 737986, 743515, 749277 A url containing the details of these bugs can be made by appending the bug number to this url: http://sourceforge.net/tracker/index.php?func=detail&group_id=61702&atid =498103&aid= Feature Requests Added ====================== The following feature requests tracked via the Sourceforge system were fixed: 690928, 703283 A url containing the details of these feature requests can be made by appending the request number to this url: http://sourceforge.net/tracker/index.php?func=detail&group_id=61702&atid =498104&aid=

ANN:modeler __getattr__ for modules
by Wiktor Sadowski 20 Jun '03

20 Jun '03

modeler ====== Some posts on class-like attribute access for modules encourged me to get some code from my not-yet-released viz module and make it available as a standalone Python C extension module. Modeler enables dynamic attribute creation/access by simply adding a __gettattr__ function to a module. Modeler doesn't replace modules with class instances,actually it doesn't make any changes to modules. Some more details and modeler.pyd for Python2.2 can be found at: http://www.wiktorsadowski.com/Python Examples of simple module-class-factory and importing two or more modules from one dll : http://www.wiktorsadowski.com/Python/modsample.html As for the source code: I will try to make it available later this month. Have fun, Wiktor Sadowski add to site.py: import modeler =========== dynmodule.py ========== def __getattr__(thismod,name): if name in thismod.__dict__.keys(): return thismod.__dict__[name] else: # in more useful cases: #thismod.__dict__[name]=anAttr #return anAttr return "Default Attr" ====================================================== Python 2.2.2 (#37, Oct 14 2002, 17:02:34) [MSC 32 bit (Intel)] on win32 Type "copyright", "credits" or "license" for more information. >>> from dynmod import whatever1,whatever2 >>> whatever1 'Default Attr' >>> whatever2 'Default Attr' >>> import dynmod >>> dynmod.foo 'Default Attr' >>> dynmod.spam 'Default Attr' >>>

[ANN] wxPython 2.4.1.2
by Robin Dunn 20 Jun '03

20 Jun '03

Announcing ---------- I'm pleased to announce the 2.4.1.2 release of wxPython, now available for download at http://wxpython.org/download.php or http://sourceforge.net/project/showfiles.php?group_id=10718&release_id=1665… What is wxPython? ----------------- wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a Python extension module that wraps the popular wxWindows cross platform GUI library, which is written in C++. wxPython is a cross-platform toolkit. This means that the same program will usually run on multiple platforms without modifications. Currently supported platforms are 32-bit Microsoft Windows, most Linux or other unix-like systems, and Macintosh OS X. New with this release is an experimental build of wxPython using GTK+ 2.x for the underlying GUI platform and it is also built with UNICODE support turned on. The RPMs for this build were made on a Mandrake 9.1 system but should probably work on other distributions with very up to date libraries. If not, an SRPM is included that can be used to rebuild the RPM on your system. If you experiment with this build please send feedback to the wxPython-users mail list. The files are currently available only on the SourceForge download page, look for the wxPythonGTK2 files at the bottom: https://sourceforge.net/project/showfiles.php?group_id=10718&release_id=166… Changes in 2.4.1.2 ------------------ Added wxScrolledPanel from Will Sadkin Added SetShape method to top level windows (e.g. wxFrame.) Changed wxSWIG to not generate Python code using apply, (since it will be deprecated in the future) wxSWIG will use spam(*args, **kw) syntax instead. Also changed the generated __repr__ methods to be a bit more informative. Made the version number information more robust and uh, informative. Also added asserts to check that the major.minor versions of wxPython and wxWindows match. Added the new wx "renamer" package that will dynamically import from the wxPython package and rename wxFooBar --> FooBar. That means that people can do imports without "import *" and can use names like wx.Frame instead of wx.wxFrame. This is phase 1 of a full transition to the new namespace. Updated Scintilla to 1.52. I also changed it to use wxListCtrl instead of wxListBox for the AutoComplete window, added the ability to use custom bitmaps in the margin and in the AutoComplete windows, and worked out how to do proper clipping of child windows on wxGTK. Patrick O'Brien's PyCrust package has been renamed to Py and now includes several new tools. As part of the change the location of the pacakge has changed as well, it is now accessible as "from wxPython import py" (or "from wx import py" using the new namespace.) There are still some transition modules in the wxPython.lib.PyCrust package that will issue a warning and then import what is needed from the new package. These will be removed in a future release. Added __nonzero__ method to wxTreeItemId, wxBitmap, wxImage, wxFont, and most other classes that have an Ok or IsOK method. This allows code like "if obj: ..." to be the same as "if obj.IsOk(): ..." Toolbars on wxMac can now have controls on them. Added wxPython.lib.analogclock module based on samples that were passed back and forth on wxPython-users a while back. Added masked edit controls (wxPython.lib.maskededit) by Jeff Childers and Will Sadkin. Updated wxTimeCtrl to use MaskedEdit. When the __class__ of a dead object is replaced with _wxPyDeadObject the __del__ of the original class is now called first. Added wxTreeListCtrl. (Looks like a wxTreeCtrl embedded in a wxListCtrl, but actually is just giving multiple columns to a wxTreeCtrl.) Added wxFutureCall, a subclass of wxTimer that makes it easy to delay a call to any Python callable object. Added wxPy versions of wxPrintPreview, wxPreviewFrame, and wxPreviewControlBar so they can be derived from in Python and be able to override the C++ virtual methods. Simplified how the wxSizer methods are wrapped, changed the name of the "option" parameter to "proportion" to match the docs ("option" is still accepted for compatibility, but this will go away in a future release,) SetItemMinSize can now take a wxSize (or 2-tuple) parameter, and Spacers can be specified with a wxSize (or 2-tuple) parameter Added wxCursorFromBits. -- Robin Dunn Software Craftsman http://wxPython.org Java give you jitters? Relax with wxPython!

Hi all, Interested in what _Tim Couper_ has to say? Have a look at the fifth EuroPython2003 interview: http://www.europython.org/other/interviews/entries/tim_couper In previous note, we made the mistake by adding unintentionally a dot to the end of the url. Thanks to the several people who reported this. For those who didn't managed to read the interview because of this, here is the link without a dot: http://www.europython.org/other/interviews/entries/martijn_faassen For the EuroPython visitors: Since the first talks start at 9:00h and everybody has to pass the registration desk to pick up their badge, the doors will be open from 7.30h am, on the first day of the conference, ie 25 june 2003. Yes this early, so for the people who start the day very early, you know what you can do :-) See you within 6 days! Regards, EuroPython
