Chiefly, I don't want to overload "pyvenv.cfg" with new behavior that's unrelated to virtual environments. I also dislike the way this file is found. If the parent directory is "C:\Program Files", then I'm not worried about finding "C:\Program Files\pyvenv.cfg" when the interpreter tries to open it. But this pattern is not safe in general when installed to an arbitrary directory, or with a portable distribution. The presence of a "._pth" file (Windows only) beside the DLL or executable bypasses the search for "pyvenv.cfg", among other things. The embedded distribution includes a ._pth that locks it down. This is another reason to use a different file to configure defaults for -X settings such as "utf8", a file that's guaranteed to always be read. >> Add an option in the installed "python.cfg" to set the name of the >> organization and application. > > That would work for, e.g. pyinstaller (which I hope already ignores these > kinds if configuration. > > But not for, e.g. web applications that expect to use virtual environments > to isolate themselves. The idea to use the profile data directories %ProgramData% and %LocalAppData% was for symmetry with how this could be supported in POSIX, which doesn't use the application directory as Windows does. The application "python.cfg" (in the directory of the executable, including a virtual environment) can support a setting to isolate it from system and user "python.cfg" files. _______________________________________________ Python-ideas mailing list -- [email protected] To unsubscribe send an email to [email protected] https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/[email protected]/message/T42D2VDMQ7JY7WYP2W3ALFHZGUYXLPZF/ Code of Conduct: http://python.org/psf/codeofconduct/
