ANN: pullparser 0.0.2b released
by jjl＠pobox.com 23 Dec '03

23 Dec '03

http://wwwsearch.sourceforge.net/pullparser This is the first beta release (and probably the last). Changes since 0.0.1a: * Renamed .tag_iter() to .tags(), and allowed it to take multiple name arguments. * .get_text() and .get_compressed_text() now no longer raise NoMoreTagsError, but return "" instead, which is both more convenient and makes the endcase saner. * Made a tarball package with setup.py etc. Requires Python 2.2. A simple "pull API" for HTML parsing, after Perl's HTML::TokeParser. Many simple HTML parsing tasks are simpler this way than with the HTMLParser module. pullparser.PullParser is a subclass of HTMLParser.HTMLParser. Example: import pullparser, sys f = file(sys.argv[1]) p = pullparser.PullParser(f) if p.get_tag("title"): title = p.get_compressed_text() print "Title: %s" % title John

ANN: mechanize 0.0.1a released
by jjl＠pobox.com 23 Dec '03

23 Dec '03

http://wwwsearch.sourceforge.net/mechanize This is the initial alpha release. In terms of features, it's pretty complete already. It seems to work pretty well, and there's a working example in the tarball. The base class of mechanize.Browser, mechanize.UserAgent is a bit dodgy, though. Requires Python 2.2, ClientCookie 0.4.12 (note version!), ClientForm 0.1.x and pullparser 0.2.b. Stateful programmatic web browsing, after Andy Lester's Perl module WWW::Mechanize. Example: import re from mechanize import Browser b = Browser() b.open("http://www.example.com/") # follow second link with element text matching regular expression response = b.follow_link(text_regex=re.compile(r"cheese\s*shop"), nr=1) # Browser passes through unknown attributes (including methods) # first to the selected HTMLForm (from ClientForm), then to the last response. # Here we use the former (the method here is __setitem__). b["cheeses"] = ["mozzarella", "caerphilly"] response2 = b.submit() # submit current form response3 = b.back() # back to cheese shop response4 = b.reload() for link in b.forms(): print form # .links() optionally accepts the keyword args of .follow_/.find_link() for link in b.links(url_regex=re.compile("python.org")): print link John

RELEASED TMDA 1.0 final (anti-spam system)
by Jason R. Mastaler 22 Dec '03

22 Dec '03

After nearly three years of collaborative hacking, TMDA 1.0 has been released. This release is highly stable, and is in production level use at many locations. TMDA is a pure-python open source anti-spam system and local mail delivery agent for Unix and Unix-like systems. TMDA fights spam using a combination of whitelists, blacklists, challenge/response system, and tagged addresses, which are special-purpose e-mail addresses such as time-dependent addresses, and addresses which only accept certain kinds of communication. For more information on TMDA, including downloading and installation instructions, please visit one of the following mirror sites: http://www.us.tmda.net/ http://www.de.tmda.net/ http://www.au.tmda.net/ Enjoy.

python.org news
by Guido van Rossum 19 Dec '03

19 Dec '03

There's good news and bad news about python.org. The good news is that the PSF is now the official, proud owner of the domain, after a successful transfer from CNRI, which has taken good care of it for many years. Nothing will change operationally, with one exception mentioned below. The bad news comes in two flavors. First of all, a glitch during the transfer (probably my own fault, although I'd like to blame Network Solutions' confusing UI) temporarily specified the wrong DNS server for the domain. This was fixed soon afterwards, but unfortunately the wrong setting propagated quickly to DNS servers over the world, and the fix seems to be propagating more slowly. Therefore mail to and from python.org has been having a hard time, and you may be having trouble accessing the python.org webserver. I hope it'll clear up in the next 24 fours. The other bad news is that the Ultraseek-based Python search service at search.python.org is no longer available. The machine was operated by CNRI on an old Sparc, and it was ready for retirement; we've put it out to pasture to punctuate the domain transfer. Fortunately, Google can be used to search the python.org website just as well; the search page at http://python.org/search/ has had a specialized link to Google for a long time, and that's now the one to use. (You can also do this yourself by simply adding site:python.org to your query on google.com.) Finally, I'd like to remind everyone of a domain that *does* continue to work glitch-free: http://pycon.org, the website for PyCon DC 2004. There are even two specialized subdomains: http://submit.pycon.org/ for speakers (you have until January 15 to submit proposals for presentations, tutorials, and so on!), and http://dc2004reg.pycon.org/ for registration -- the early bird rate is valid until January 31! --Guido van Rossum (home page: http://www.python.org/~guido/)

RELEASED Python 2.3.3 (final)
by Anthony Baxter 19 Dec '03

19 Dec '03

On behalf of the Python development team and the Python community, I'm happy to announce the release of Python 2.3.3 (final). Python 2.3.3 is a bug-fix release of Python 2.3. A couple of serious bugs related to weakrefs and the cyclic garbage collector have been fixed, along with a number of bugs in the standard library. See the release notes on the web page for more details. For more information on Python 2.3.3, including download links for various platforms, release notes, and known issues, please see http://www.python.org/2.3.3 Highlights of this new release include: - A couple of serious bugs in the interactions of weakrefs and cyclic GC have been squashed. - At shutdown, the second call to the cyclic garbage collector has been removed. This caused more problems than it solved. - The xml.parsers.expat module now provides Expat 1.95.7. - Bug #823328: urllib2's HTTP Digest Auth support works again. - See http://www.python.org/2.3.3/NEWS.html for other bugfixes. Highlights of the previous major Python release (2.3) are available from the Python 2.3 page, at http://www.python.org/2.3/highlights.html Enjoy the new release, Anthony Anthony Baxter anthony(a)python.org Python 2.3.x Release Manager (on behalf of the entire python-dev team)

cx_OracleTools 7.2
by Anthony Tuininga 18 Dec '03

18 Dec '03

What is it? 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 http://www.computronix.com/utilities.shtml (it may be a few days before the second site is updated) What's new? 1) Added new tools ExportColumn and ImportColumn for exporting (importing) CLOB and BLOB columns from (into) an Oracle database. 2) Include package used for debugging. 3) When using DescribeObject, check if the object with the given name matches an object in the database, including case. If the object cannot be found, check for an object in the database by converting the argument to uppercase. Finally, if the name is not found and is not qualified with a schema owner, search the public synonyms for one by that name and describe that object instead. 4) Added feedback to DbDebugger indicating on what database the connection has been established and on what pipe name the debugger is listening. 5) Added optional argument to specify a filename into which to put the output created by DescribeObject. This is of particular use on Windows which doesn't handle redirection very well, particularly in GUI programs. -- Anthony Tuininga anthony(a)computronix.com Computronix Distinctive Software.
