[Python-Dev] is the concept of 'reference ownership' no long applicable in Python 3.4?
Hi, I noticed the following changes in the C API manuals from 3.3.5 (and earlier versions) to 3.4. I don't know if these changes are deliberate and imply that we C extension developers no longer need to care about 'reference ownership' because of some improvements in 3.4. Could anyone clarify it?

[Python-Dev] make a Windows installation package (.msi) for Python 3.3
To Python Windows Release Managers: My name is Jianfeng Mao and I am a software developer at the U2 group in Rocket Software (http://u2.rocketsoftware.com/). I am currently working on a project to embed a slightly customized Python interpreter in our product. For easy installation and setup, we hope to be able to do the standard Python installation during the installation of our software. Basically I want to create a .msi file that can be called to install the full Python if the user needs this new feature. Brian Curtin (br...@python.orgmailto:br...@python.org) pointed me to Tools/msi/msi.py for the Windows MSI builder. I tried to follow the instructions in the README but couldn't make it to work after a few twists and turns. Brian mentioned that few people needs to do this and only release managers handle the packaging of Python. I have listed the steps I have done in my attempt to create the .msi file. Please let me know if I have missed anything or done anything wrong. 1. hg clone http://hg.python.org/cpython 2. cd cpython 3. hg update 3.3 4. cd tools\buildbot, edit build.bat to change the configuration from Debug to Releaes; edit external.bat, change DEBUG=1 to DEBUG=0 5. go back to cpython\ and run tools\buildbot\build.bat 6. cd PC, then do 'nmake -f icons.mak' 7. cd ..\tools\msi 8. c:\python27\python msi.py WARNING: nm did not run successfully - libpythonXX.a not built cl /O2 /D WIN32 /D NDEBUG /D _WINDOWS /MT /W3 /c msisupport.c Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 16.00.40219.01 for 80x86 Copyright (C) Microsoft Corporation.

[Python-Dev] Any script to create the installation pacakge of Python 3.3.1 on Windows and *NIX?
To Python-Dev committers: I am working on a project to embed a slightly customized Python interpreter in our own software. For easy installation and setup, we want to be able to do the standard Python installation as part of the installation of our product. So far I have successfully customized and built Python 3.3.1 (including the subprojects) on Windows but I can't find anything in the source distribution to allow me package the binaries/modules etc into a MSI just like the one on the download page on python.org. So I am asking for information regarding how to package Python build for installation on both Windows and *NIX platforms. Your help will be greatly appreciated.
