Hello, I am trying to reach Greg Ward to get a maintainer access to Distutils at PyPI, but his email address at python.net (and some other) doesn't work anymore. Anyone knows how to reach him ? Thanks Tarek -- Tarek Ziadé | Association AfPy | www.afpy.org Blog FR | http://programmation-python.org Blog EN | http://tarekziade.wordpress.com/

gdbinit and Gdb wrapper objects
by Larry (Laurence) Cotton Feb. 23, 2009

Feb. 23, 2009

Hi I am trying to use python gdb to debug a python process that is hanginig - it is a thread lock situation. I have been trying to use the gdbinit macros to help me in this, but when I attempt to access f->f_nlocals in a PyEval_EvalFrameEx object it informs There is no member named f_nlocals. Consequently pylocals does not work. 1) Does anyone have any idea why this might be happening ? 2) I have been unable to find any documentation (other than the gdbinit macros) about the make up of … [View More]

.pythonrc.py in man page
by Mitchell L Model Feb. 23, 2009

Feb. 23, 2009

The python man page, dated 2005 even in 3.1, has this curious entry: ~/.pythonrc.py User-specific initialization file loaded by the user module; not used by default or by most applications. 1. I couldn't figure out what the user module is. 2. I couldn't figure out what "not used by default or by most applications" meant: what would cause it to get loaded when python starts up? how would an application load it even if the user's environment didn't cause … [View More]

Tracker archeology
by Daniel (ajax) Diniz Feb. 22, 2009

Feb. 22, 2009

Hi all, For the past two days I've been doing some housekeeping *cough*spamming*cough* on the tracker, mostly on ancient and/or easy bugs. So far, ten bugs have been closed (thanks Antoine, Barry, Benjamin, Guilherme, Martin and Raymond). I nominated some other bugs (below) for closing and added a few simple patches, with a couple more pending feedback. If anyone is interested in being added as nosy for any category of bugs, let me know and I'll do that as I scan the tracker. Iff this kind … [View More]

Seeming unintended difference between list comprehensions and generator expressions...
by Josiah Carlson Feb. 22, 2009

Feb. 22, 2009

Recently I found the need to generate some constants inside a class body. What I discovered was a bit unintuitive, and may not be intended... In 2.5 and 2.6: >>> class foo: ... x = {} ... x.update((i, x.get(i, None)) for i in xrange(10)) ... Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<stdin>", line 3, in foo File "<stdin>", line 3, in <genexpr> NameError: global name 'x' is not defined >>> class … [View More]

code.interact() locals + globals?
by Rocky Bernstein Feb. 22, 2009

Feb. 22, 2009

I notice code.interact() in Python 2.6 has a parameter for locals but not globals. Should it? Ultimately, *exec* is used underneath so I don't see a technical reason why it couldn't add a global parameter. Also, although one could pass in a dictionary that is the merger or update() of locals() and globals(), this has a couple of downsides. First, if the intention is to allow update of local and global variables, combining the two into a single dictionary wreaks havoc. Even if one doesn't … [View More]
