`poetry run` exits on KeyboardInterrupt

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Arch Linux
• Poetry version: 0.11.4

Issue

KeyboardInterrupt is not properly handled when executing with poetry run. If a python script attempts to catch a KeyboardInterrupt exception, instead of it being handled, the entire poetry run ... command exists completely.

Here is an example of running the python interpreter.

$ python
>>> try:
...     while True:
...         pass
... except KeyboardInterrupt:
...     print('hello')
...
^Chello
>>> print('I am still in the interpreter')

poetry run python
>>> try:
...     while True:
...         pass
... except KeyboardInterrupt:
...     print('hello')
...
^Chello
$ echo 'I am back to the shell'

Even worse is the way this affects poetry scripts. Completely exiting the script instead of handling the KeyboardInterrupt exception. pyproject.toml

[tool.poetry.scripts]
script = 'script:main'

script.py

def main():
    try:
        while True:
            pass
    except KeyboardInterrupt:
        print('Never reached when executed using `poetry run script`')

$ poetry run script
^C

This does not happen when the package is installed with pip and the script is executed.

$ poetry build
$ pip install dist/project.whl
$ script
^CNever reached when executed using `poetry run script`

In my experience closing tickets due to being untouched usually just means a valid ticket wasn’t addressed for a long time. I’m glad to hear that this case is an exception and that stale [bot] might go away.
