question re: default branch and release clone
by Chris Jerdonek Aug. 28, 2012

Aug. 28, 2012

Now that the 3.3 release clone has been created, can someone clarify what changes are allowed to go into the default branch? Is it the same policy as if the changes were going into the release clone directly (i.e. code freeze unless you have Georg's approval), or are future changes for 3.3.1 okay, or is the default branch for changes that would go into 3.4? If the policy is the same, when and how do we anticipate changing things for the default branch? Thanks, --Chris

Sphinx issue in What's New in Python 3.3 doc
by Victor Stinner Aug. 27, 2012

Aug. 27, 2012

Hi, In the first example of the "PEP 409: Suppressing exception context" section, I read "from None...". http://docs.python.org/dev/whatsnew/3.3.html#pep-409-suppressing-exception-… It's confusing because I don't remember what was the last choice for the PEP: None or ... :-) The reST "code" looks correct in Doc/whatsnew/3.3.rst: ... raise AttributeError(attr) from None ...

[RELEASED] Python 3.3.0 release candidate 1
by Georg Brandl Aug. 25, 2012

Aug. 25, 2012

On behalf of the Python development team, I'm delighted to announce the first release candidate of Python 3.3.0. This is a preview release, and its use is not recommended in production settings. Python 3.3 includes a range of improvements of the 3.x series, as well as easier porting between 2.x and 3.x. Major new features and changes in the 3.3 release series are: * PEP 380, syntax for delegating to a subgenerator ("yield from") * PEP 393, flexible string representation (doing away with the … [View More]

Snakebite build slaves and developer SSH/GPG public keys
by Trent Nelson Aug. 24, 2012

Aug. 24, 2012

Hi folks, I've set up a bunch of Snakebite build slaves over the past week. One of the original goals was to provide Python committers with full access to the slaves, which I'm still keen on providing. What's a nice simple way to achieve that in the interim? Here's what I was thinking: - Create a new hg repo: hg.python.org/keys. - Committers can push to it just like any other repo (i.e. same ssh/authz configuration as cpython). - Repo … [View More]is laid out as follows: keys/ <python username>/ ssh (ssh public key) gpg (gpg public key) - Prime the repo with the current .ssh/authorized_keys (presuming you still use the --tunnel-user facility?). That'll provide me with everything I need to set up the relevant .ssh/authorized_keys stuff on the Snakebite side. GPG keys will be handy if I ever need to send passwords over e-mail (which I'll probably have to do initially for those that want to RDP into the Windows slaves). Thoughts? As for the slaves, here's what's up and running now: - AMD64 Mountain Lion [SB] - AMD64 FreeBSD 8.2 [SB] - AMD64 FreeBSD 9.1 [SB] - AMD64 NetBSD 5.1.2 [SB] - AMD64 OpenBSD 5.1 [SB] - AMD64 DragonFlyBSD 3.0.2 [SB] - AMD64 Windows Server 2008 R2 SP1 [SB] - x86 NetBSD 5.1.2 [SB] - x86 OpenBSD 5.1 [SB] - x86 DragonFlyBSD 3.0.2 [SB] - x86 Windows Server 2003 R2 SP2 [SB] - x86 Windows Server 2008 R2 SP1 [SB] All the FreeBSD ones use ZFS, all the DragonFly ones use HAMMER. DragonFly, NetBSD and OpenBSD are currently reporting all sorts of weird and wonderful errors, which is partly why I want to set up ssh access sooner rather than later. Other slaves on the horizon (i.e. hardware is up, OS is installed): - Windows 8 x64 (w/ VS2010 and VS2012) - HP-UX 11iv2 PA-RISC - HP-UX 11iv3 Itanium (64GB RAM) - AIX 5.3 RS/6000 - AIX 6.1 RS/6000 - AIX 7.1 RS/6000 - Solaris 9 SPARC - Solaris 10 SPARC Nostalgia slaves that probably won't ever see green: - IRIX 6.5.33 MIPS - Tru64 5.1B Alpha If anyone wants ssh access now to the UNIX platforms in order to debug/test, feel free to e-mail me directly with your ssh public keys. For committers on other Python projects like Buildbot, Django and Twisted that may be reading this -- yes, the plan is to give you guys Snakebite access/slaves down the track too. I'll start looking into that after I've finished setting up the remaining slaves for Python. (Setting up a keys repo will definitely help (doesn't have to be hg -- feel free to use svn/git/whatever, just try and follow the same layout).) Regards, Trent "that-took-a-bit-longer-than-expected" Nelson. [View Less]

root@python doc cron job failure messages
by Terry Reedy Aug. 22, 2012

Aug. 22, 2012

root@python is indirectly trying to send doc cron job failure messages to the python-checkings list. headers below. They are caught and held for moderation since "Blind carbon copies or other implicit destinations are not allowed." I think it is a mistake to send these messages to checkins, which has enough checkins traffic already, but I do not know who is responsible to fix the situation. The last two examples: "home/docs/devguide/documenting.rst:773: WARNING: term not in glossary: … [View More]bytecode" "abort: error: Connection timed out" Headers: Return-Path: <docs(a)python.org> X-Original-To: python-checkins(a)python.org Delivered-To: python-checkins(a)mail.python.org Received: from albatross.python.org (localhost [127.0.0.1]) by mail.python.org (Postfix) with ESMTP id 3X2G3z3xCNzQjK; Wed, 22 Aug 2012 19:30:23 +0200 (CEST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=python.org; s=200901; t=1345656623; bh=conhuN6h+7FXE7LPMr0jHBM5W+Bs5Ld9a8QDgyfQyA4=; h=Date:Message-Id:From:To:Subject:Content-Type; b=lVY4n5KqDW1Qzzy4ngaHTMcO7wCbBlDQzSPWDqaNsUGwrBrcjtY1X8+hiDNsDxUA/ A/wYxK1w887LE2mbzqzONtg2zoUau0cvTvG52sg0aXHqWLidRNbvJZ3WxYeYSC1ph/ pK5u6M9JBd5a1HOiyiTOA5uTu6DWXATy04FTkjdM= X-Spam-Status: OK 0.009 X-Spam-Evidence: '*H*': 0.98; '*S*': 0.00; 'received:dinsdale.python.org': 0.03; 'error:': 0.05; 'subject:build': 0.07; 'subject: <': 0.09; 'message- id:@dinsdale.python.org': 0.16; 'subject:home': 0.16; 'timed': 0.16; 'from:addr:python.org': 0.17; 'subject:/': 0.28; 'connection': 0.30; 'received:python.org': 0.31; 'received:org': 0.36; 'subject:-': 0.40; 'header:Message-Id:1': 0.62; 'to:addr:docs': 0.68; 'subject:@': 0.81 Received: from localhost (HELO mail.python.org) (127.0.0.1) by albatross.python.org with SMTP; 22 Aug 2012 19:30:23 +0200 Received: from dinsdale.python.org (svn.python.org [IPv6:2001:888:2000:d::a4]) (using TLSv1 with cipher AES256-SHA (256/256 bits)) (No client certificate requested) by mail.python.org (Postfix) with ESMTPS; Wed, 22 Aug 2012 19:30:23 +0200 (CEST) Received: from docs by dinsdale.python.org with local (Exim 4.72) (envelope-from <docs(a)dinsdale.python.org>) id 1T4El5-0007tw-4K for docs(a)dinsdale.python.org; Wed, 22 Aug 2012 19:30:23 +0200 Date: Wed, 22 Aug 2012 19:30:23 +0200 Message-Id: <E1T4El5-0007tw-4K(a)dinsdale.python.org> From: root(a)python.org (Cron Daemon) To: docs(a)dinsdale.python.org Subject: Cron <docs@dinsdale> /home/docs/build-devguide Content-Type: text/plain; charset=UTF-8 X-Cron-Env: <SHELL=/bin/sh> X-Cron-Env: <HOME=/home/docs> X-Cron-Env: <PATH=/usr/bin:/bin> X-Cron-Env: <LOGNAME=docs> -- Terry Jan Reedy [View Less]

3.3 str timings
by Terry Reedy Aug. 21, 2012

Aug. 21, 2012

The issue came up in python-list about string operations being slower in 3.3. (The categorical claim is false as some things are actually faster.) Some things I understand, this one I do not. Win7-64, 3.3.0b2 versus 3.2.3 print(timeit("c in a", "c = '…'; a = 'a'*1000+c")) # ord(c) = 8230 # .6 in 3.2, 1.2 in 3.3 Why is searching for a two-byte char in a two-bytes per char string so much faster in 3.2? Is this worth a tracker issue (I searched and could not find one) or is there a known … [View More]

Jython roadmap
by "Juancarlo Añez (Apalala)" Aug. 21, 2012

Aug. 21, 2012

It seems that Jython is under the Python Foundation, but I can't find a roadmap, a plan, or instructions about how to contribute to it reaching 2.7 and 3.3. Are there any pages that describe the process? Thanks in advance, -- Juanca
