What's New text on future maintenance
by A.M. Kuchling 10 May '10

10 May '10

FYI: I've just added the text below to the "What's New" document for 2.7. I wanted to describe how 2.7 will probably be maintained, but didn't want to write anything that sounded like an iron-clad guarantee of a maintenance timespan. Does this text seem like a reasonable set of statements? --amk Python 2.7 is intended to be the last major release in the 2.x series. Though more major releases have not been absolutely ruled out, the Python maintainers are planning to focus their efforts on Python 3.x. This means that 2.7 will remain in place for a long time, running production systems that have not been ported to Python 3.x. Two consequences of the long-term significance of 2.7 are: * It's very likely the 2.7 release will have a longer period of maintenance compared to earlier 2.x versions. Python 2.7 will continue to be maintained while the transition to 3.x is in progress, and that transition will itself be lengthy. Most 2.x versions are maintained for about 4 years, from the first to the last bugfix release; patchlevel releases for Python 2.7 will probably be made for at least 6 years. * Because 2.7 will be running production applications, a policy decision was made to silence warnings only of interest to developers by default. Silencing :exc:`DeprecationWarning` and its descendants prevents users from seeing warnings triggered by an application. (Carried out in :issue:`7319`.) You can re-enable display of :exc:`DeprecationWarning` messages by running Python with the :option:`-Wdefault` (short form: :option:`-Wd`) switch, or you can add ``warnings.simplefilter('default')`` to your code.

Re: [Python-Dev] Running Clang 2.7's static analyzer over the code base
by Brett Cannon 10 May '10

10 May '10

I'll just do a single entry saying that the static analyzer was used and not list the files. And in reply to Benjamin's question about the whitespace, I guess it actually doesn't matter. More important to clean up in py3k.

[RELEASED] Python 2.7 beta 2
by Benjamin Peterson 09 May '10

09 May '10

On behalf of the Python development team, I'm elated to announce the second beta release of Python 2.7. Python 2.7 is scheduled (by Guido and Python-dev) to be the last major version in the 2.x series. 2.7 will have an extended period of bugfix maintenance. 2.7 includes many features that were first released in Python 3.1. The faster io module, the new nested with statement syntax, improved float repr, set literals, dictionary views, and the memoryview object have been backported from 3.1. Other features include an ordered dictionary implementation, unittests improvements, a new sysconfig module, and support for ttk Tile in Tkinter. For a more extensive list of changes in 2.7, see http://doc.python.org/dev/whatsnew/2.7.html or Misc/NEWS in the Python distribution. To download Python 2.7 visit: http://www.python.org/download/releases/2.7/ While this is a development release and is thus not suitable for production use, we encourage Python application and library developers to test the release with their code and report any bugs they encounter to: http://bugs.python.org/ 2.7 documentation can be found at: http://docs.python.org/2.7/ Enjoy! -- Benjamin Peterson 2.7 Release Manager benjamin at python.org (on behalf of the entire python-dev team and 2.7's contributors)

Did I miss the decision to untabify all of the C code?
by Eric Smith 09 May '10

09 May '10

It looks like we're moving ahead with removing tabs. Was there consensus on this? Last I saw Antoine had written a script that might do what we want, but hadn't been thoroughly tested. Now I've seen a few checkins for files that have been run through the script. What gives? And why do this so close to 2.7? I don't think it will cause any problems, but it's hard to review commits to ensure they have no changes when there's a rush of large commits near a release. Eric.

Parallel test execution on buildbot
by exarkun＠twistedmatrix.com 09 May '10

09 May '10

Hi all, Has anyone considered using regrtest's -j option in the buildbot configuration to speed up the test runs? Antoine Pitrou pointed out that even for single CPU slaves, this could be a win due to the number of tests that spend time sleeping or waiting on I/O. And on slaves with multiple CPUs it would clearly be even better. eg, I don't know what hardware is actually in the Solaris slave (bot loewis-sun), but if it has the full 4 UltraSPARCs that it could, then running with -j4 or -j5 there might bring its runtime down from nearly 100 minutes to 20 or 25 - competitive with some of the more reasonable slaves.

bugs.python.org intermittently not working.
by Terry Reedy 08 May '10

08 May '10

Saturday eve (us, eastern). Last night I had intermittent problems with bugs.python.org: issues not being fetched, submissions not being recorded. David Abrahams reported 'bugs.python.org seems to be down' is his urlparse thread. Right not, I have a fetch and submission 'loading' for over a minute, after fetching an issue a minute before. The new beta2 page came up with no problems. The submission just stopped with Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request POST /issue8641. Reason: Error reading from remote server Apache/2.2.9 (Debian) mod_python/3.3.1 Python/2.5.2 mod_ssl/2.2.9 OpenSSL/0.9.8g Server at bugs.python.org Port 80

audience-instructors for Teach Me Python Bugfixing needed
by Catherine Devlin 07 May '10

07 May '10

Hey, everybody... I'm Catherine, a database administrator who makes up excuses to write Python instead. I'm not actually here as a core developer, but as somebody who hopes to become a developer and recruit some more, which brings me to my question: Who lives close enough to Ohio to make it to PyOhio this summer? I want to use PyOhio to create new Python devs (including myself), but I need some existing ones to seed the process. I need a few veterans (3?) who can commit to come to PyOhio and take part as audience/instructors in a "Teach Me [Python core / standard library] Bugfixing" session. (See http://catherinedevlin.blogspot.com/2010/04/bugfixing-at-pyohio.html.) The PyOhio Call for Proposals is up May 10 so I'd better find you quick! I'm pretty much ignorant enough to lead a Teach Me session. In a Teach Me session, the person at the projector *doesn't* know the material. Instead, she asks the audience questions ("How do I find a bug to work on?"), and they talk her through it. It's based on Teach Me Twisted, a mind-blowing session Steve Holden led at PyCon 2008 ( http://catherinedevlin.blogspot.com/2008/03/teach-me-twisted.html). I think it's a fantastic way to teach, but it depends on some veterans being in the audience. There are folks in the greater Python community eager to get hold of a video of such a session... if we do this well, it could become an important tool in keeping the quality of core Python code high. And all I need from you, my audience-instructors, is a promise to show up (no preparation necessary). Can you make it? Can you pass the appeal on to others you know of? Thanks! Hope to see you in July! -- - Catherine http://catherinedevlin.blogspot.com/ *** PyOhio 2010 * July 31 - Aug 1 * Columbus, OH * pyohio.org ***
