Offline mode no longer works in Chrome 118.0.5993.70

[SteveLauC]

Env

• Chrome: Version 118.0.5993.70 (Official Build) unknown (64-bit)

• Rust Search Extension: 1.12.0

• Host: Fedora 38 Workstation/GNOME 44.5

• Rust:

  $ rustup -V
  rustup 1.26.0 (5af9b9484 2023-04-05)
  info: This is the version for the rustup toolchain manager, not the rustc compiler.
  info: The currently active `rustc` version is `rustc 1.73.0 (cc66ad468 2023-10-03)`

Erroneous Behavior

Choose the entry I want to check, press enter, nothing happens

Steps to reproduce

1. Enable the offline mode with the following path

   file:///home/steve/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/share/doc/rust/html/
   

   the path should be right:

   $ rustup doc --std --path
   /home/steve/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/share/doc/rust/html/std/index.html

2. Open a new tab

3. input rs, the a space

4. input Vec, choose std::vec::Vec, press the enter button

Workaround I have tried

1. Restart chrome
2. Reinstall the extension

Thanks for the feedback. Chrome has restricted access to local file URLs since 118.0, see the announcement and workaround here: https://developer.chrome.com/docs/extensions/whatsnew/#changes-to-file-scheme

Thanks for the response!

Per the announcement, you need to explicitly enable this in

chrome://extensions => extension details

But I didn't find it on that page :(, please see the screenshot below:

Neither for me to find that setting. 🥲 Maybe you can change to this workaround: https://rust.extension.sh/faq/#why-local-file-rust-doc-not-work-properly-on-firefox

Get it, I don't want to spawn a server just for serving local file accesses so I think I will just use the online doc for the moment, thanks for looking into the issue!

In the post provided by the Chrome announcement I found this potential solution:

I ended up adding "optional_host_permissions": [ "file:///*" ]
This way the "Allow access to file URLs" is shown, navigation works, but I don't actually get read permission.

Maybe we can give it a try?
