#19248 `from ..foo import *` glob imports are silently ignored by Rust parser Issue created by huonw Describe the bug The new Rust parser doesn't seem to understand a 'plain' parent import, like

from ..file1 import *

. It does understand

from ..file1 import func

, though. This reproducer constructs a directory structure like:

.
├── pants.toml
└── src
    └── a
        ├── BUILD
        ├── file1.py
        └── file2.py

where

file2.py

has

from .file1 import *

. It runs

pants peek src/a/file2.py

with both the python parser (which shows a dependency on

src/a/file1.py

) and with the Rust parser (which doesn't). Unlike #19173, there's no inference warnings either.
