Bug when renaming file (notebook 6.4.12)

[jinzhen-lin]

Describe the bug In notebook 6.4.12，we cannot rename file sometimes.

To Reproduce Steps to reproduce the behavior:

1. Install notebook 6.4.12
2. Start notebook with root_dir="/home/foobar"
3. Create a directory named abc (or any name with length len(root_dir) - len("Untitled") - 1)
4. Create a notebook with default filename 'Untitled.ipynb'
5. Rename the notebook to any other filename

Then you should got the error message

File "/home/xxxxxxx/.miniconda3/lib/python3.8/site-packages/notebook/services/contents/filemanager.py",
line 579, in rename_file raise web.HTTPError(400, f'Cannot rename hidden file or directory {os_path!r}')
NameError: name 'os_path' is not defined

Expected behavior

Rename the file successfully.

According to the error message, I found a typo here (os_path is not defined, it should be old_path). .https://github.com/jupyter/notebook/blob/3e5b767ddbc3526729cadbc69fe472ffc3ec2e7e/notebook/services/contents/filemanager.py#L578-L579 And I notice that the result of is_hidden(old_path, self.root_dir) is true, this is because the result of "abc/Untitled.ipynb"[len("/home/foobar"):] is .ipynb and it is treated as a hidden file.

It seems that this bug is introduced by this commit https://github.com/jupyter/notebook/commit/f69eb96cff7149b38bca068f4b7faaa7baf55902 .

Same error. I have to rename it in the file folder after I close the jupyter notebook.

Hi， After I rename it, it will be fine. I continue to check the information. It may have the same name as a file in the system

notebook/services/contents/filemanager.py

There is an error on this file rename function (line 500+)

The only way how to solve this situation is to downgrade...

pip3 install --upgrade notebook=="6.4.11"

This problem also exists in version 6.5.2

@zyzand The latest release of Notebook, 6.5.3 should include the fix by @yacchin1205. Would you be able to upgrade to 6.5.3 and see if you still experience this issue?

It works after I upgrade to version 6.5.3. Thanks.
