Browsing through excluded_paths causes "noisy" logs to show

[grios-stratio]

Description

When configuring the excluded_paths and browsing in the Jupyter lab UI through the excluded paths, the jupyter server logs show a somewhat noisy (since it includes the traceback) message, like this:

2024-07-04 12:32:34 WARNING - 0 handlers write_error:774 wrote error: 'Not Found'
    Traceback (most recent call last):
      File "/home/grios/miniconda3/envs/analytic-4.0/lib/python3.9/site-packages/tornado/web.py", line 1769, in _execute
        result = await result  # type: ignore
      File "/home/grios/miniconda3/envs/analytic-4.0/lib/python3.9/site-packages/jupyterlab_git/handlers.py", line 57, in prepare
        raise tornado.web.HTTPError(404)
    tornado.web.HTTPError: HTTP 404: Not Found

It seems this is caused because the git handler is raising a web.HTTPError(404) in the prepare method:

jupyterlab-git/jupyterlab_git/handlers.py

Lines 41 to 51 in 6cfb33d

	async def prepare(self):
	"""Check if the path should be skipped"""
	await ensure_async(super().prepare())
	path = self.path_kwargs.get("path")
	if path is not None:
	excluded_paths = self.git.excluded_paths
	for excluded_path in excluded_paths:
	if fnmatch.fnmatchcase(path, excluded_path):
	raise tornado.web.HTTPError(404)

and the base APIHandler of jupyter_server logs the error with its traceback in the write_error:
https://github.com/jupyter-server/jupyter_server/blob/f2d40f692c29e155349b179d57a454e7f23ea898/jupyter_server/base/handlers.py#L774.

Some time ago (#1165) an error was not raised there and we only had in the logs the less-intrusive message.

2024-07-04 12:32:34 WARNING - 0 log log_request:99 404 POST /git/somepath/show_prefix?1720089154189 (9157f51ccdb94089b5aade51e22a1a68@127.0.0.1) 4.48ms referer=http://localhost:8888/lab/workspaces/auto-B

It would be nice if it no log message was logged (I think the perfect solution would be for the frontend to not make the request in the first place for the excluded paths) or for the message to be less noisy (not raising web.HTTPError? overriding write_error in the handler? 🤔 )

Reproduce

1. Configure the c.JupyterLabGit.excluded_paths = ["/somepath", "/somepath/*] in jupyter_server_config.py
2. Launch jupyterlab
3. Create (if does not exists) a folder in called "somepath" in the workspace.
4. Browse in the JupyterLab UI through folders inside somepath and the "noisy" log message should appear.

Expected behavior

No log message shown (or at least no traceback)
