Attention Bazaar mirror users
by Barry Warsaw Feb. 27, 2009

Feb. 27, 2009

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've just upgraded the Bazaar mirrors on code.python.org to use bzr 1.12. We now have the opportunity to upgrade the repository format for better performance. Because of the bzr-svn requirement, we need a "rich root" format. Upgrading to 1.9-rich-root could buy us some significant performance improvements, but it will require all clients to upgrade to at least bzr 1.9, which was released on November 7, 2008. I would like to do this upgrade. If you are currently using the Bazaar mirrors at code.python.org and upgrading your client to at least bzr 1.9 would be a hardship, please contact me. If I don't hear any objections by say Tuesday, I'll go ahead and do the repo upgrades. Thanks, Barry -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (Darwin) iQCVAwUBSZ7HwHEjvBPtnXfVAQIlxAQAk0ze8AHLY8aezrH35+Vv4tXloLy/FV1M GHF2QzLBaV45Hr4d3i8Os32eaSvhWyFbCGeBZtm3q3pOwPy9ST/tDdI0XBwjd0M1 FV1Pg3v97IYeI6Pa1HKz0sKxbygACiZ9iQWde3b85zXEhsaZfXo7RiendmMkYift Uvw0WWJZ1DU= =sCFZ -----END PGP SIGNATURE-----

Distutils in PEP 291
by Tarek Ziadé Feb. 27, 2009

Feb. 27, 2009

Hello, If no one objects, I would like to: - put Distutils back into PEP 291 for Python 2.3 compatibility - fix the two issues that prevent the current trunk to run with Python 2.3 to 2.5 (see http://bugs.python.org/issue5052 and the patch I worked on) Regards Tarek -- Tarek Ziadé | Association AfPy | www.afpy.org Blog FR | http://programmation-python.org Blog EN | http://tarekziade.wordpress.com/

A suggestion: Do proto-PEPs in Google Docs
by Stephen J. Turnbull Feb. 26, 2009

Feb. 26, 2009

[Aside to Guido: Oops, I think I accidentally sent you a contentless reply. Sorry!] As a suggestion, I think this is relevant to everybody who might be writing a PEP, so I'm cross-posting to Python-Dev. Probably no discussion is needed, but Reply-To is set to Python-Ideas. On Python-Ideas, Guido van Rossum writes: > On Thu, Feb 19, 2009 at 2:12 AM, Greg Ewing wrote: > > Fifth draft of the PEP. Re-worded a few things slightly > > to hopefully make the proposal a bit clearer up front. > > Wow, how I long for the days when we routinely put things like this > under revision control so its easy to compare versions. FWIW, Google Docs is almost there. Working with Brett et al on early drafts of PEP 0374 was easy and pleasant, and Google Docs gives control of access to the document to the editor, not the Subversion admin. The ability to make comments that are not visible to non-editors was nice. Now that it's in Subversion it's much less convenient for me (a non-committer). I actually have to *decide* to work on it, rather than simply raising a browser window, hitting "refresh" and fixing a typo or two (then back to "day job" work). The main problem with Google Docs is that is records a revision automatically every so often (good) but doesn't prune the automatic commits (possibly hard to do efficiently) OR mark user saves specially (easy to do). This lack of marking "important" revisions makes the diff functionality kind of tedious. I don't know how automatic the conversion to reST was, but the PEP in Subversion is a quite accurate conversion of the Google Doc version. Overall, I recommend use of Google Docs for "Python-Ideas" level of PEP drafts.

New curses module method addchstr, etc.
by Heracles Feb. 26, 2009

Feb. 26, 2009

Hello, I submitted my first patch recently for the curses color_set and wcolor_set functions. I am now working on addchstr, addchnstr, mvaddchstr, mvaddchnstr, mvwaddchstr, mvwaddchnstr, waddchstr and waddchnstr. I have implemented the non window specific methods as follows: /* Window.addchstr Inserted Steve Owens 2/25/2005 */ static PyObject * PyCursesWindow_AddChstr(PyCursesWindowObject *self, PyObject *args) { int x, y, n; PyStringObject *pS; switch (PyTuple_Size(args)) { case 1: if (!PyArg_ParseTuple(args, "S;(String) expected for waddchstr", &pS)) return NULL; return PyCursesCheckERR(waddchstr(self->win, (chtype*)PyString_AsString(pS)), "waddchstr"); case 2: if (!PyArg_ParseTuple(args, "Si;(String, int) expected for waddchnstr", &pS, &n)) return NULL; return PyCursesCheckERR(waddchnstr(self->win, (chtype*)PyString_AsString(pS), n), "waddchnstr"); case 3: if (!PyArg_ParseTuple(args,"iiS;(int, int, String) expected for mvwaddchstr", &y, &x, &pS)) return NULL; return PyCursesCheckERR(mvwaddchstr(self->win, y, x, (chtype*)PyString_AsString(pS)), "mvwaddchstr"); case 4: if (!PyArg_ParseTuple(args,"iiSi;(int, int, String, int) expected for mvwaddchnstr", &y, &x, &pS, &n)) return NULL; return PyCursesCheckERR(mvwaddchnstr(self->win, y, x, (chtype*)PyString_AsString(pS), n), "mvwaddchnstr"); default: PyErr_SetString(PyExc_TypeError, "addchstr requires 1 to 4 arguments"); } return NULL; } Now the thing is that when I make calls from python like so: curses.addchstr(5,10, "@ < Row 5, Col 10") curses.addchstr(8,10, "Below you should see ABCDEFG") curses.addchstr(9,10, "ABCDEFG") curses.addchstr(12,10, "Below you should see ABCD") curses.addchnstr(13,10, "ABCDEFGHI", 4) What prints out on the screen is gobledygook not the strings you would expect below. Any thoughts on how to correctly convert the PyStringObject arguments to chtype* pointers so that the ncurses library will be able to understand them? -- View this message in context: http://www.nabble.com/New-curses-module-method-addchstr%2C-etc.-tp22211983p… Sent from the Python - python-dev mailing list archive at Nabble.com.

Bug tracker house cleaning.
by Raymond Hettinger Feb. 26, 2009

Feb. 26, 2009

ISTM, that when closing duplicate bug reports, both should reference one another so that the combined threads don't get lost. Also, assigning bugs to people who haven't asked to handle them doesn't seem like it is actually cleaning-up anything. If something is assigned to someone, I usually assume they intend to work on it at some point. In contrast, unassigned means that no one is currently handling it. Just thought I would toss this out since the status of so many bugs/patches is being updated today. Raymond

PyCon 2009: Call for sprint projects
by Jacob Kaplan-Moss Feb. 26, 2009

Feb. 26, 2009

Python-related projects: join the PyCon Development Sprints! The development sprints are a key part of PyCon, a chance for the contributors to open-source projects to get together face-to-face for up to four days of intensive learning and development. Newbies sit at the same table as the gurus, go out for lunch and dinner together, and have a great time while advancing their project. Sprints are one of the best parts of PyCon; in 2008 over 250 sprinters came for at least one day! If your project would like to sprint at PyCon, now is the time to let us know. We'll collect your info and publish it so that participants will have time to make plans. We'll need to get the word out early so that folks who want to sprint have time to make travel arrangements. In the past, some have been reluctant to commit to sprinting: some may not know what sprinting is all about; others may think that they're not "qualified" to sprint. We're on an ongoing mission to change that perception: * We'll help promote your sprint. The PyCon website, the PyCon blog, the PyCon podcast, and press releases will be there for you. * PyCon attendees will be asked to commit to sprints on the registration form, which will include a list of sprints with links to further info. * We will be featuring a "How To Sprint" session on Sunday afternoon, followed by sprint-related tutorials, all for free. This is a great opportunity to introduce your project to prospective contributors. We'll have more details about this later. * Some sponsors are helping out with the sprints as well. There's also cost. Although the sprinting itself is free, sprints have associated time and hotel costs. We can't do anything about the time cost, but we may have some complimentary rooms and funding available for sprinters. We will have more to say on financial aid later. Those who want to lead a sprint should send the following information to pycon-organizers(a)python.org: * Project/sprint name * Project URL * The name and contact info (email and/or telephone) for the sprint leader(s) and other contributors who will attend the sprint * Instructions for accessing the project's code repository and documentation (or a URL) * Pointers to new contributor information (setup, etc.) * Any special requirements (projector? whiteboard? flux capacitor?) We will add this information to the PyCon website and set up a wiki page for you (or we can link to yours). Projects should provide a list of goals (bugs to fix, features to add, docs to write, etc.), especially some goals for beginners, to attract new sprinters. The more detail you put there, the more prepared your sprinters will be, and the more results you'll get. In 2008 there were sprints for Python, TurboGears, Pylons, Django, Jython, WSGI, PyGame, Bazaar, Trac, PyCon-Tech, OLPC, Orbited, PyPy, Grok, and many others. We would like to see all these and more! Sprints will start with an introductory session on Sunday, March 29; this session will begin immedately after PyCon's scheduled portion ends. The sprints themselves will run from Monday, March 30 through Thursday, April 2, 2009. You can find all these details and more at http://us.pycon.org/2009/sprints/. If you have any questions, feel free to contact me directly. Thank you very much, and happy coding! Jacob Kaplan-Moss <jacob(a)jacobian.org>

Shared ABCs for the IO implementation
by Antoine Pitrou Feb. 25, 2009

Feb. 25, 2009

Hello, I would like to know if both IO implementations (the C one and the Python one) should share their ABCs (IOBase, RawIOBase, etc.). It looks preferable to me but since I'm not very familiar with ABCs I'd like to be sure it's the good choice. (of course, the *implementations* won't be shared at all. Just the virtual inheritance information) Regards Antoine.
