RELEASED Python 2.6a2 and 3.0a4
by Barry Warsaw 05 Apr '08

05 Apr '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On behalf of the Python development team and the Python community, I'm happy to announce the second alpha release of Python 2.6, and the fourth alpha release of Python 3.0. Please note that these are alpha releases, and as such are not suitable for production environments. We continue to strive for a high degree of quality, but there are still some known problems and the feature sets have not been finalized. These alphas are being released to solicit feedback and hopefully discover bugs, as well as allowing you to determine how changes in 2.6 and 3.0 might impact you. If you find things broken or incorrect, please submit a bug report at http://bugs.python.org For more information and downloadable distributions, see the Python 2.6 web site: http://www.python.org/download/releases/2.6/ and the Python 3.0 web site: http://www.python.org/download/releases/3.0/ We are planning one more alpha release of each version, followed by two beta releases, with the final releases planned for August 2008. See PEP 361 for release details: http://www.python.org/dev/peps/pep-0361/ Enjoy, - -Barry Barry Warsaw barry(a)python.org Python 2.6/3.0 Release Manager (on behalf of the entire python-dev team) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) iQCVAwUBR/WImHEjvBPtnXfVAQJmoQP+MzqNDI+Xt8zua/FE7Ca4TVXoIIy2uoOm I1i3+vmevZ9vtAb9hcGwfEgPY4LSwb9Js4KnJJWMPaMuFJK4NgGoiMdj+t42zDbQ bEzfBUOCoVkejLRxIQnWeJf1Hu8JocYyCHIRffv57/QdKpHuiSs8aE8GIT3STo3o I88H5NY1GgI= =WT2z -----END PGP SIGNATURE-----

Python source code on Bazaar vcs
by Barry Warsaw 04 Apr '08

04 Apr '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm happy to announce that we now have available for public consumption, the Python source code for 2.5, 2.6 and 3.0 available under the Bazaar distributed version control system. The current Subversion repository is still the master copy of the source code. We have not made a decision to move to Bazaar officially, nor have we made a decision to even move off of Subversion. We're making these branches available exactly so that you, the Python developer community, can kick the tires and see if it makes sense to move to a different vcs. Nothing will happen until after the Python 2.6/3.0 releases anyway. All the gory details are documented here: http://www.python.org/dev/bazaar These branches are available both for core Python developers with commit privileges, and the wider world of developers without commit privileges. It's this latter group that I think will find the most compelling immediate benefit from using Bazaar, because they will no longer need to maintain their own changes using a mass of patch files. For more information on Bazaar in general, see: http://bazaar-vcs.org You will probably be most interested in the Bazaar mirrors of the Subversion master repository. We have a cron job that updates Bazaar from Subversion every 15 minutes. It is also possible to push changes made in your Bazaar branches into the Subversion master, so you can keep reasonably up-to-date and interact with the Python source code solely via Bazaar. Please let me know if you have any questions or anything in the docs referenced above aren't clear. I know I need to document the Bazaar- >Subversion workflow in more detail. Huge thanks go out especially to Thomas Wouters who sprinted with me yesterday on getting the whole infrastructure up and running. Thanks also to Martin v. Loewis, Sean Reifschneider, and the folks here at Pycon from the Bazaar project, Ian, Andrew, John, and Edwin. Enjoy, - -Barry -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) iQCVAwUBR+K+H3EjvBPtnXfVAQL6bwP/d0XKx0mRPgzdOD6zCPwwRl8y2kxWV9Vl zVwN07cK8IlwMa9M470MsERuXuD8hmeXnPgnrUcrX9HciwldmY8C33t0f8GaOk1J iD4Od1midlIaJJiMd+JcFk9NbX3Rwc4HMj3s8jKjjdlGrFe77ei9DCZ/HMl/iG5K fyyjXo4HLEE= =Gcjq -----END PGP SIGNATURE-----

Annotations support in python
by Heshan Suriyaarachchi 04 Apr '08

04 Apr '08

Hi, I need to work with annotations as it is said in [1]. Currently I am using python 2.5.1. I would like to know whether the next release of python will support this feature. If the next version support this feature I would like to know when are you planning to release it. I used the __future__ module but I could not get the annotations with it.

When you say rebuild, I assume you mean the change I made to the pythoncore project's pre-link step to call kill_python.exe, and not to the post-build step of kill_python that runs itself? Personally, when I'm doing development, if I've got the pcbuild\python_d.exe console open, it's usually to test one liners, I'm not using it to do anything important. If I forget to close it before I kick off a build, it's annoying running into errors at the link stage, I'd certainly prefer the build system to kill off anything that'll inhibit a successful link before actually linking. > > What do others that do Windows development think? I don't have a problem changing the build behaviour if the approach I've taken is generally disliked. I agree with Christian: in interactive sessions, the F7 key should not kill my running testsuite... I prefer the linker errors. Please do this only for buildbot builds! Or maybe have it controlled by an enviroment variable. -- Amaury Forgeot d'Arc

xmlrpclib and dates before 1900
by Ralf Schmitt 04 Apr '08

04 Apr '08

Hi all, anyone care to take a look at: http://bugs.python.org/issue2014 It's about xmlrpclib not being able to send datetime objects with dates before 1900. I would like to see this go in and would also like to work on http://bugs.python.org/issue1745722 (xmlrpc wsgi support). But this only makes sense if someone also commits it... Regards, - Ralf

Tools\buildbot\kill_python.c can't be helping our cause
by Trent Nelson 03 Apr '08

03 Apr '08

Looking into some of the recent Windows buildbot failures, I see things like this: sqlite3 : error PRJ0008 : Could not delete file 'c:\buildbot\trunk.heller-windows-amd64\build\PCbuild\amd64\sqlite3_d.dll'. build-amd64.bat doesn't go through the kill_python.c hoopla, so I figure the above error is being caused by the fact that an erroneous/stalled python_d.exe from a previous run is still open. I was looking at modifying kill_python.c to accept an 'x64' argument if we want to kill amd64\python_d.exe instead of the usual 32-bit exe, however, this caught my attention: if ((strstr(path, "pcbuild\\python_d.exe") != NULL) || (strstr(path, "\\build\\python.exe") != NULL)) { printf("Terminating %s (pid %d)\n", path, pids[i]); if (!TerminateProcess(hProcess, 1)) { printf("Termination failed: %d\n", GetLastError()); return 1; } return 0; That'll kill the first python_d.exe instance it finds matching the given path; given that our buildbots run trunk/release25-maint/py3k in parallel, it seems as though it wouldn't be hard for us to get into a situation where kill_python.exe ends up killing the wrong python_d.exe (i.e. trunk checkin, trunk builds, starts testing, py3k checkin, calls kill_python.exe, kills trunk's python_d.exe that was in the middle of testing). That can't be helping our cause, unless I'm missing something... Unless anyone advises otherwise, I'll start on a patch. Trent.

FW: [issue2513] 64bit cross compilation on windows
by Mark Hammond 03 Apr '08

03 Apr '08

FYI, I've uploaded a patch that provides for cross-compilation on Windows between 32 and 64 bit platforms - all comments invited! Thanks, Mark -----Original Message----- From: Mark Hammond [mailto:report@bugs.python.org] Sent: Sunday, 30 March 2008 6:01 PM To: mhammond(a)users.sourceforge.net Subject: [issue2513] 64bit cross compilation on windows New submission from Mark Hammond <mhammond(a)users.sourceforge.net>: I've taken the liberty of adding Trent, Christian and Martin to the nosy list as I know they are actively, if reluctantly interested in this. This patch allows the distutils to cross-compile on Windows. It has been tested on x86 and amd64 platforms, with both platforms successfully able to natively and cross-compile extension modules and create binary distributions. To cross-compile, specify '--plat-name' to the build command (valid values are 'win32', 'win-amd64' and 'win-ia64'). This option name was chosen to be consistent with the bdist_dumb command. I've included the docs I added below (which are also in the patch), but note that as with native compilation using distutils, it's not necessary to set any environment variables or do anything else special with your environment to make this work. The patch also adds a x64 target for the 'bdist_wininst' target, which it creates as distutils/command/wininst-9.0-amd64.exe. This executable is necessary even for bdist_wininst to work natively on x64, but is still included here for simplicity. To assist with testing, I've also added a distutils setup.py script to the PC/example_nt directory. This is capable of creating bdist_wininst executables for both native and cross platforms; 'setup.py build --platname=win-amd64 bdist_wininst' will create an amd64 installer on an x86 machine. The patch has not been tested with a Visual Studio environment without cross-compile tools installed - it will obviously fail, but its not clear how ugly this failure will be. Below is the text I added to docs/distutils/builtdist.rst: Cross-compiling on Windows ===================== Starting with Python 2.6, distutils is capable of cross-compiling between Windows platforms. In practice, this means that with the correct tools installed, you can use a 32bit version of Windows to create 64bit extensions and vice-versa. To build for an alternate platform, specify the :option:`--plat-name` option to the build command. Valid values are currently 'win32', 'win-amd64' and 'win-ia64'. For example, on a 32bit version of Windows, you could execute:: python setup.py build --plat-name=win-amd64 to build a 64bit version of your extension. The Windows Installers also support this option, so the command:: python setup.py build --plat-name=win-amd64 bdist_wininst would create a 64bit installation executable on your 32bit version of Windows. Note that by default, Visual Studio 2008 does not install 64bit compilers or tools. You may need to reexecute the Visual Studio setup process and select these tools. ---------- assignee: mhammond components: Distutils files: windows-cross-compile.patch keywords: 64bit, patch messages: 64743 nosy: Trent.Nelson, ctheune, loewis, mhammond severity: normal status: open title: 64bit cross compilation on windows type: feature request versions: Python 2.6 Added file: http://bugs.python.org/file9900/windows-cross-compile.patch __________________________________ Tracker <report(a)bugs.python.org> <http://bugs.python.org/issue2513> __________________________________
