New submission from Brian Curtin <cur...@acm.org>: When running 32-bit Python on a 64-bit version of Windows, therefore running the process in WOW64 mode, platform.machine returns a misleading value. When running in WOW64, the processor architecture is masked to appear as "x86" when the machine is actually "AMD64" (which you see on a 64-bit app on 64-bit OS).
The change involves looking at an environment variable only set on WOW64 processes to see the native architecture. See http://blogs.msdn.com/david.wang/archive/2006/03/26/HOWTO-Detect-Process-Bitness.aspx The patch does not include any test, as I'm not really sure how you could test this without using the change itself to figure out when it should be tested. Suggestions would be appreciated. ---------- components: Library (Lib), Windows files: arch_misrepresented.diff keywords: needs review, patch, patch messages: 98890 nosy: brian.curtin priority: normal severity: normal stage: patch review status: open title: 32-bit Python on 64-bit Windows reports incorrect architecture type: behavior versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2 Added file: http://bugs.python.org/file16143/arch_misrepresented.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7860> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
