'Retry as sudo' doesnt work

[paul0ss]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.95.3 x64
• OS Version: Kali Linux 6.11.2-amd64
• VS Code source: Microsoft Repository

Steps to Reproduce:

1. Open a file that is not writable by the user
2. Edit the file
3. Try to save it
4. Error pops up stating that not enough permissions
5. Retry as Sudo option appears
6. Enter password
7. Saving process freezes up

People discussing this issue here: #70403
Given information from the above-mentioned source I was able to debug the problem.

According to the developer the write a file with sudo goes through following process:

1. we write the desired contents into a temp file (here)
2. we import sudo-prompt (here)
3. we ask it to run "code --file-write tmpfile target"

After running VSCode with --verbose flag I have noticed the target file is not set:
[sudo-prompt] running command: "/usr/share/code/bin/code" --file-write "/home/paul0ss/.config/Code/code-elevated-DYqaVPH4"

This is probably the reason why the file write doesnt succeed but also doesnt throw any exception stating that permission was denied.

We changed the solution to only require 1 file, so the execution looks fine.

Are there more errors in the full logs?

No other errors. Here is bigger a snippet from the log beginning with the initial permission denied error:

PS: The Apparmor is turned off to cut off any third party interference and the bug was replicated on a fresh Kali install on another computer as well to exclude the possibility of the bug occurring in my specific environment.

Thanks, this line is relevant:

Curious when you try this again, can you check the contents of this file and if it exists on disk? It would have a different name each time you try, so you need to get it from the logs.
