[New-bugs-announce] [issue31451] PYTHONHOME is not absolutized

[Xiang Zhang]

New submission from Xiang Zhang:

I find that PYTHONHOME is not absolutized even after VM initialization. So sys.prefix will be "usr" if I execute `PYTHONHOME=usr python`.  This could lead to libraries like pip to fail if the current directory is changed, such as by `os.chdir`.

I am not sure this is a bug.  But I see PYTHONPATH is absolutized in site.py.  Maybe PYTHONHOME should be too? Or it's by design.
