I would like an svn account
by Victor Stinner 09 Jan '09

09 Jan '09

Hi, I already asked in September to get an svn account to be able to commit directly patches to trunk (or other branches like py3k). My query was rejected because I didn't know Python core enough (and maybe other reasons that I don't know). I helped to fix many issues using the bug tracker. The bigger patch was the bytes filename support for Python3, accepted by Guido (after a long review ;-)). Why an svn account instead of just using the amazing bug tracker? Just because there are not enough people to review/commit patches on the tracker and so there are more and more open issues (and so more and more lost patches) :-( I will be able to work faster using the svn. -- Victor Stinner aka haypo http://www.haypocalc.com/blog/

[patch 0/8] [RFC] cross compiling python 3.0
by Robert Schwebel 09 Jan '09

09 Jan '09

Embedded people have cross compiled python for quite some time now, with more or less success. These activities have taken place in various embedded build systems, such as PTXdist, OpenEmbedded and others. I suppose instead of wasting the time over and over again, without proper review by the Python core developers, I would like to find out if it is possible to get cross compilation support integrated in the upstream tree. This patch series reflects what we currently have in PTXdist. Please see it as an RFC. It is probably not perfect yet, but I would like to see some feedback from you Python guys out there. Do you see issues with these patches? Would it be possible in general to get something similar to this series into the Python mainline? Robert -- Pengutronix e.K. | Dipl.-Ing.

Decoder functions accept str in py3k
by Antoine Pitrou 09 Jan '09

09 Jan '09

Hello, I've just noticed that in py3k, the decoding functions in the codecs module accept str objects as well as bytes: # import codecs # c = codecs.getdecoder('utf8') # c('aa') ('aa', 2) # c('éé') ('éé', 4) # c = codecs.getdecoder('latin1') # c('aa') ('aa', 2) # c('éé') ('Ã©Ã©', 4) Is it a bug? Regards Antoine.

Needless assert in ceval.c?
by skip＠pobox.com 09 Jan '09

09 Jan '09

I realize assert() is compiled out except in debug builds, but the assert in the while loop following the fast_block_end label in ceval.c seems misleading. It looks like it should be hoisted out of the loop and only checked before entering the loop. There are no jumps into the loop. why is not assigned WHY_YIELD within the loop. If you assert before the loop once I think that will be sufficient and more clearly state the intent. fast_block_end: assert(why != WHY_YIELD); /* move the assert here */ while (why != WHY_NOT && f->f_iblock > 0) { PyTryBlock *b = PyFrame_BlockPop(f); /* get rid of the assert here */ if (b->b_type == SETUP_LOOP && why == WHY_CONTINUE) { ... } ... } /* unwind stack */ Reported to the tracker: http://bugs.python.org/issue4888 Skip

OSCON 2009: Call For Participation
by Aahz 09 Jan '09

09 Jan '09

The O'Reilly Open Source Convention has opened up the Call For Participation -- deadline for proposals is Tuesday Feb 3. OSCON will be held July 20-24 in San Jose, California. For more information, see http://conferences.oreilly.com/oscon http://en.oreilly.com/oscon2009/public/cfp/57 -- Aahz (aahz(a)pythoncraft.com) <*> http://www.pythoncraft.com/ "Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it." --Brian W. Kernighan

error in doc for fcntl module
by Mike Coleman 08 Jan '09

08 Jan '09

In the doc page for the fcntl module, the example below is given. This seems like an error, or at least very misleading, as the normal usage is to get the flags (F_GETFL), set or unset the bits you want to change, then set the flags (F_SETFL). A reader might think that the example below merely sets O_NDELAY, but it also stomps all of the other bits to zero. If someone can confirm my thinking, this ought to be changed. import struct, fcntl, os f = open(...) rv = fcntl.fcntl(f, fcntl.F_SETFL, os.O_NDELAY)

Is raising SystemError during relative import the best solution?
by Brett Cannon 08 Jan '09

08 Jan '09

So it turns out that if you try to do a relative import where a parent is not loaded, it raises a SystemError. This has been in there since Guido added package support back in the day. But this seems more like an ImportError than a SystemError to me. My guess is that the original purpose was to signify someone specified some relative import name without the proper stuff to make the name resolve to what it should be. But that to me is still an ImportError as the name came out wrong, not that the system did something incorrectly. So I would like to propose to remove the SystemError and make it an ImportError. Anyone object? -Brett

What's New in Python 2.6: no string exceptions
by Daniel Stutzbach 08 Jan '09

08 Jan '09

After reading "What's New in Python 2.6" and then upgrading, I quickly noticed an omission: string exceptions are no longer supported and raise a TypeError. It seems like this should be mentioned in the "Porting to Python 2.6" section at minimum, or perhaps more prominently since this change will break code in many small projects (e.g., code from Python 2.5's tutorial). Were any other previously-deprecated features removed for 2.6? Also, it might be nice if whatever tool tests the code in the tutorial would treat Deprecation warnings as hard errors, so new users don't learn features slated for possible removal. -- Daniel Stutzbach, Ph.D. President, Stutzbach Enterprises, LLC <http://stutzbachenterprises.com>

improvements for mmap
by Neal Becker 08 Jan '09

08 Jan '09

I'd like to suggest some improvements from mmap 1) mmap assign to slice only accepts a string. This is unfortunate, because AFAIK a string can only be created by copying data, and this is wasteful for large data transfers. mmap should accept any object supporting buffer protocol as well as string. 2) buffer (mmap_obj) gives a read_only buffer. There should be a way to make this read_write. 3) mmap_obj does not support weak ref.
