[New-bugs-announce] [issue8955] import doesn't notice changes to working directory

[James]

New submission from James <purpleidea at gmail.com>:

Attempting to change the working directory and then import based on that change has no effect. Import seems impossible. Attached is tarball example. As seen below, bar1.py can import foo from src, however bar2.py bar3.py and bar4.py cannot, despite their respective scripts changing their cwd. Below is results of a terminal session. Thanks in advance.

james at hostname:~$ tree import_bug/
import_bug/
|-- bar1.py
|-- __init__.py
|-- src
|   |-- foo.py
|   `-- __init__.py
`-- test
    |-- bar2.py
    |-- bar3.py
    |-- bar4.py
    |-- bar5.py
    `-- __init__.py
