You may have missed "if not_a_console(hStdout): real_stdout = False". not_a_console uses GetFileType and GetConsoleMode to check whether that handle is directed to something other than a console. > But is it always the case? The technique used here for detecting a console is almost the same as the code for IsConsoleRedirected at http://blogs.msdn.com/b/michkap/archive/2010/05/07/10008232.aspx , or in WriteLineRight at http://blogs.msdn.com/b/michkap/archive/2010/04/07/9989346.aspx (I got it from that blog, can't remember exactly which page). [This code will give a false positive in the strange corner case that stdout/stderr is redirected to a console *input* handle. It might be better to use GetConsoleScreenBufferInfo instead of GetConsoleMode, as suggested by http://stackoverflow.com/questions/3648711/detect-nul-file-descriptor-isatty-is-bogus/3650507#3650507 .] > What about pythonw.exe? I just tested that, using pythonw run from cmd.exe with stdout redirected to a file; it works as intended. It also works (for both console and non-console cases) when the handles are inherited from a parent process. Incidentally, what's the earliest supported Windows version for Py3k? I see that http://www.python.org/download/windows/ mentions Windows ME. I can fairly easily make it fall back to never using WriteConsoleW on Windows ME, if that's necessary. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue1602> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
