Exception in script in ~/.ipython/profile_default/startup causes other scripts to not execute

~/.ipython/profile_default/startup/a.py と b.py で失敗を再現し、その後、kernel の startup-script 実行のエントリポイントを追跡してください。Jupyter notebook で動作を確認してください。後のスクリプトは、前のスクリプトで例外が発生した後も実行されるべきであり、失敗したスクリプトはエラーを示す何らかの表示を生成するべきです。

Summary

If one of the files in your ~/.ipython/profile_default/startup throws an exception, then any other file that executes later (i.e. is lexicographically higher, because startup scripts are executed in lexicographical order) will not be executed.

To reproduce

1. Run these commands:

echo 'raise Exception' > ~/.ipython/profile_default/startup/a.py
echo 'x = 123' > ~/.ipython/profile_default/startup/b.py

2. Open a Jupyter notebook, type x into a cell, and press enter

Expected behavior

It outputs 123. Ideally it also shows some information indicating that a.py failed to run.

Actual behavior

It shows NameError: name 'x' is not defined. It also doesn't give any indication that a.py (or b.py) failed to run.

System configuration

Kernel version:

Python 3.11.6 (main, Oct  2 2023, 20:46:14) [Clang 14.0.3 (clang-1403.0.22.14.1)]
Type 'copyright', 'credits' or 'license' for more information
IPython 8.16.1 -- An enhanced Interactive Python. Type '?' for help.

Python packages:

$ python3 -m pip show ipykernel | grep Version
Version: 6.25.2

OS version: macOS 13.3.1

Notes

If you run

mv ~/.ipython/profile_default/startup/{a,c}.py

then it will successfully define x (because b.py runs before c.py).
