Rietveld integration problem?
by Vinay Sajip May 9, 2012

May 9, 2012

I recently added an issue http://bugs.python.org/issue14712 to track PEP 405 integration. The code is in my sandbox repo, and I've created a patch using the "Create Patch" button on the tracker. The diff has been created, but I don't seem to see a "review" link to Rietveld. The issue is on Rietveld but for some reason the patch set hasn't attached to it. An earlier version of the patch (which I've since unlinked) had the same problem - even after several days, the "review" link never appeared.… [View More]

c/ElementTree XML serialisation
by Alex Leach May 9, 2012

May 9, 2012

Hi, I was just reading through the ElementTree source code, in order to figure out how I might override the serialisation on the text nodes of <script> and <style> elements. It doesn't appear I can do that with Element instances though. I'm making an SVG generating tool, and because SVG uses the XML namespace, [c]ElementTree serialises 'script' Elements like any other XML Element. However, if I was using the HTML namespace instead, I wouldn't suffer from this, because of the … [View More]

Debian wheezy, amd64: make not finding files for bz2 and other packages
by Edward C. Jones May 8, 2012

May 8, 2012

I use up-to-date Debian testing (wheezy), amd64 architecture. I have made a "clone" of the developmental version of Python 3.3. "make -s -j3" prints: ==== ... Python build finished, but the necessary bits to build these modules were not found: _bz2 _curses _curses_panel _dbm _gdbm _lzma _sqlite3 _ssl readline zlib To find the necessary bits, look in setup.py in detect_modules() for the module's name.

PEP 405 (pyvenv) and system Python upgrades
by Carl Meyer May 8, 2012

May 8, 2012

Hi all, The recent virtualenv breakage in Python 2.6.8 and 2.7.3 reveals an issue that deserves to be explicitly addressed in PEP 405: what happens when the system Python underlying a venv gets an in-place bugfix upgrade. If the bugfix includes a simultaneous change to the interpreter and standard library such that the older interpreter will not work with the newer standard library, all venvs created from that Python installation will be broken until the new interpreter is copied into … [View More]

Python 3.3 cannot find BeautifulSoup but Python 3.2 can
by Edward C. Jones May 8, 2012

May 8, 2012

I use up-to-date Debian testing (wheezy), amd64 architecture. I compiled and installed Python 3.3.0 alpha 3 using "altinstall". Debian wheezy comes with python3.2 (and 2.6 and 2.7). I installed the Debian package python3-bs4 (BeautifulSoup). I also downloaded a "clone" developmental copy of 3.3. Python3.3a3 cannot find module bs4. Neither can the "clone". Python3.2 can find the module. Here is a session with the "clone": > ./python Python 3.3.0a3+ (default:10ccbb90a8e9, May 6 … [View More]

Assigning copyright...
by stefan brunthaler May 7, 2012

May 7, 2012

Hi, I only had little time to spend for my open sourcing efforts, which is why I could not get back to python-dev any time earlier... Yesterday I forward-ported my patches to revision 76549 (13c30fe3f427), which only took 25mins or so (primarly due to the small changes necessary to Python itself and the stability of that parts.) Thanks to a colleague of mine (Per Larsen) I reimplemented some of the more ugly parts of the code generator, too. Guido's answer from the last thread was that I … [View More]

May 7, 2012

On behalf of the Python development team, I'm happy to announce the third alpha release of Python 3.3.0. This is a preview release, and its use is not recommended in production settings.

Major new features and changes in the 3.3 release series are: * PEP 380, Syntax for Delegating to a Subgenerator ("yield from") * PEP 393, Flexible String Representation (doing away with the … [View More]
