Issue: Using Git Bash for Windows (2.34.1-64) and Python 3.9.9, a git
path is incorrectly prepended to environment variables in Python code.
Sample Output of a simple Python script pulling an environment
variable - this is the expected output, where Python is given the
correct environment variables for both absolute directory paths and
non-directory paths - OS should not matter:
(gitfu-XXGUYdp7) C:\Users\Leland\code\gitfu>type foobar.py
from os import environ
from sys import stdout
stdout.write(f'environ: {environ["TEST_DIR_BROKEN"]}\n')
stdout.write(f'environ: {environ["TEST_DIR_WORKING"]}\n')
(gitfu-XXGUYdp7) C:\Users\Leland\code\gitfu>echo %TEST_DIR_BROKEN%
/foo/bar
(gitfu-XXGUYdp7) C:\Users\Leland\code\gitfu>echo %TEST_DIR_WORKING%
foo/bar
(gitfu-XXGUYdp7) C:\Users\Leland\code\gitfu>python foobar.py
environ: /foo/bar
environ: foo/bar
(gitfu-XXGUYdp7) C:\Users\Leland\code\gitfu>powershell Get-Command python.exe

Application python.exe
3.9.915... C:\Users\Leland\.virtualenvs\gitfu-XXGUYdp7\Scripts\python.exe
(gitfu-XXGUYdp7) C:\Users\Leland\code\gitfu>
Sample output when the same set of commands is run in git bash -
absolute path has been altered the relative path has not been:
$ cat foobar.py
from os import environ
from sys import stdout
stdout.write(f'environ: {environ["TEST_DIR_BROKEN"]}\n')
stdout.write(f'environ: {environ["TEST_DIR_WORKING"]}\n')
Leland@local MINGW64 ~/code/gitfu
$ echo $TEST_DIR_BROKEN
/foo/bar
Leland@local MINGW64 ~/code/gitfu
$ echo $TEST_DIR_WORKING
foo/bar
Leland@local MINGW64 ~/code/gitfu
$ python foobar.py
environ: C:/Users/Leland/AppData/Local/Programs/Git/foo/bar
environ: foo/bar
Leland@local MINGW64 ~/code/gitfu
$ which python
/c/Users/Leland/.virtualenvs/gitfu-XXGUYdp7/Scripts/python
Leland@local MINGW64 ~/code/gitfu
$
Is there anything else I'm missing on why the same Python script would
read environment variables differently than what is read from Git Bash
itself or why the exact same Python code reads the environment
variable correctly when run from a command prompt and not in Git Bash?
In both cases I am using the same Python virtual environment. Other
environment variables (e.g. non-absolute directory paths) appear to be
read correctly. I'm assuming that this is a git issue given the
