Matching multiple regexes
by MRAB March 3, 2010

March 3, 2010

I've thought of a possible additional feature for my regex module and I'm looking for opinions. Occasionally there's a question about matching multiple regexes and someone might suggest combining them into one regex using "|". The feature would be to allow regex.compile, etc, to accept a list or tuple of regex strings. These would be combined into a single regex internally. The match object would get a new attribute .index which would give the index of the regex string which matched. An … [View More]

Deprecation warnings in Python 2.7
by Florent Xicluna March 3, 2010

March 3, 2010

Hello, I would like to open a discussion on the meaning of deprecation warnings in 2.7. I assume, but I may be wrong, that 2.7 will be the last version in the 2.x branch. With this assumption, we should not find many things deprecated in 2.7 final. On the other hand, the list of py3k deprecation warnings is increasing a lot. And more users will probably start to move from 2.7 to the 3.1 release. While working on ticket #7092 and #7849, we started to discuss some proposals to simplify the … [View More]

PEP 3188: Implementation Questions
by Meador Inge March 3, 2010

March 3, 2010

Hi All, Recently some discussion began in the issue 3132 thread ( http://bugs.python.org/issue3132) regarding implementation of the new struct string syntax for PEP 3118. Mark Dickinson suggested that I bring the discussion on over to Python Dev. Below is a summary of the questions\comments from the thread. Unpacking a long-double =================== 1. Should this return a Decimal object or a ctypes 'long double'? 2. Using ctypes 'long double' is easier to implement, but precision is … [View More]

ElementTree.tostring() returning str by default in Py3.2
by Stefan Behnel March 3, 2010

March 3, 2010

Hi, I just noticed that the xml.etree.ElementTree.tostring() function in Py3.2 returns a str object by default, unless an encoding is specified. This is a backwards incompatible change compared to ET 1.2. For one, it breaks tons of tests in lxml's compatibility test suite. Previously, the default encoding was 'ASCII', and tostring() was guaranteed to always return a byte string. According to svn blame, this was changed by GvR in rev. 56841. Is there any reasoning behind this? Stefan

Packaging JIT-less versions of Python
by Collin Winter March 3, 2010

March 3, 2010

Hey packaging guys, We recently committed a change to Unladen Swallow [1] that moves all the JIT infrastructure into a Python extension module. The theory [2] behind this patch was that this would make it easier for downstream packagers to ship a JIT-less Python package, with the JIT compiler available via an optional add-on package. Some questions for you, so we're not shooting blind here: - Have you guys thought about how a JIT-enabled Python 3 installation would be packaged by your … [View More]

Python and Windows 2000
by "Martin v. Löwis" March 2, 2010

March 2, 2010

I don't recall whether we have already decided about continued support for Windows 2000. If not, I'd like to propose that we phase out that support: the Windows 2.7 installer should display a warning; 3.2 will stop supporting Windows 2000. Opinions? Regards, Martin

Status of PEP 381
by Jacob Kaplan-Moss March 1, 2010

March 1, 2010

Hey folks -- Can someone point me to some information on what's going on with PEP 381 (PyPI mirroring)? There's a bunch of XXX'd material, and it doesn't appear that pypi.python.org implements the statistics or providing parts. I'd be willing -- happy, actually -- to fill in the missing pieces, but only if I'm not stepping on anyone's toes. I'd also need some help adding code to pypi.python.org if that's a necessary part -- I'm not very good at finding my way around that codebase. Thanks, Jacob

Who needs to be added to python-committers?
by Brett Cannon March 1, 2010

March 1, 2010

Any people who have commit privileges not subscribed to python-committers? We have gained some new people recently so I just want to make sure everyone is subscribed to the list. Also, anyone have an email address for Hirokazu Yamamoto? His mailbox is full so Mailman unsubscribed him. -Brett

Draft PEP on RSON configuration file format
by Patrick Maupin March 1, 2010

March 1, 2010

All: Finding .ini configuration files too limiting, JSON and XML to hard to manually edit, and YAML too complex to parse quickly, I have started work on a new configuration file parser. I call the new format RSON (for "Readable Serial Object Notation"), and it is designed to be a superset of JSON. I would love for it to be considered valuable enough to be a part of the standard library, but even if that does not come to pass, I would be very interested in feedback to help me polish the … [View More]
