[issue27263] Tkinter sets the HOME environment variable, breaking scripts
Jarrod Petz added the comment: eryksun, now I understand this is a bit more challenging because tkinter is the underlying library doing this and it is shared by other apps. Though I still don't feel that just because its been like this since 1995 means it should stay this way. This is something which breaks other code following the python os.path.expanduser way(and probably other thing looking at the evitonmeny HOME). Not all people will try getting to the bottom of why, esspecially if they are a new user. It should just work. Would iy be possible for tkinter to allow the user/app to decide the behavior? Ie. Have a setting(s)/switch which allows the default behavior of setting and using HOME to be overiden. By doing that existing apps remain unchanged and apps like IDLE could change this behavior to whatever they want when they are ready. I think os.path.expanduser() behavior is by far more logical. Preference USERPROFILE if HOME is missing. USERPROFILE on windows is needed to even login. HOMEDRIVE/HOMEPATH is not. -- ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27263> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue27263] IDLE sets the HOME environment variable breaking scripts
Jarrod Petz added the comment: Worked around this by setting HOME to be USERPROFILE before IDLE starts Rather then change the system/user environment permanently. I edited the Idle script which the windows shortcut seems to run below. C:\Python35\Lib\idlelib\idle.pyw At the top of the script I added import os os.environ['HOME'] = os.environ['USERPROFILE'] -- ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27263> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue27263] IDLE sets the HOME environment variable breaking scripts
Jarrod Petz added the comment: It also makes things none deterministic. As when I am off the domain or my network drive H:\ is unavailable it works and uses USERPROFILE. -- ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27263> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue27263] IDLE sets the HOME environment variable breaking scripts
New submission from Jarrod Petz: It seems IDEL is setting the environment variable 'HOME' on windows. Specifically I am on windows 8.1 This is extremly annoying and bad as according the code and doco, os.path.expanduser will preference this variable above others such as USERPROFILE. https://docs.python.org/3/library/os.path.html#os.path.expanduser This is causing scripts/libraries and in my case the AWS SDK boto3/botocore modules to break. As they are looking for config files in the users home location using os.path resolution order which should be %USERPROFILE% in my case as I don't have HOME set. But because idle is setting HOME to what looks to be my HOMEPATH and HOMEDRIVE this is making the AWS SDK unable to pickup the credential files required. path = "~/.aws/credentials" print(os.path.expanduser(path)) Should be C:\Users\myUserName/.aws/credentials But is instead H:\/.aws/credentials Please stop IDLE from setting this environment variable. Running the same scripts with python.exe or pythonw.exe works fine. -- components: IDLE messages: 267761 nosy: Jarrod Petz priority: normal severity: normal status: open title: IDLE sets the HOME environment variable breaking scripts type: behavior versions: Python 3.5 ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27263> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
