[🚀 Feature]: Offline Mode in Selenium Manager

[titusfortner]

Feature and motivation

This would address issues like #11636 as well as some of the concerns people have raised around changes in perception of security considerations.

I think this should be managed in Rust instead of in each binding and the grid, since there is more functionality the Manager should be doing than just downloads. So that means it needs to be an environment variable.

Usage example

ENV["SELENIUM_MANAGER_DOWNLOADS_DISABLED"] = true

I made some comments in the original feature request (#11636).

Regarding the proposed environment variable proposed in this issue (SELENIUM_MANAGER_DOWNLOADS_DISABLED), sure, it can be implemented on the Rust side. But do you mean disable all downloads but keep using the cache?

To make it more compliant with the current implementation, maybe we can add a Selenium Manager flag called --disable-downloads to carry out that function. The use of envs is aligned with the proposal on #11690. In that case, the naming convention I proposed for that would convert the --disable-downloads flag to SE_DISABLE_DOWNLOADS.

The original reason/request (#11636) was made because we changed the original Grid behavior. We were downloading drivers and making them available by default. The original behavior was to detect the available drivers and build the stereotypes from there.

I made a fix in this commit 6cb3e2f

Aside of the Grid use case, no one has asked for this feature. So I believe we do not need this right now.

Hmm, yeah, I guess for bindings we just tell people to specify the location of the driver if you don't want to toggle selenium manager.

[titusfortner]

yeah, I'm going to close this as I think what Diego has done is good enough, can create a new issue if someone wants more.

[titusfortner]

I'm reopening this one. If we are going to move functionality for checking whether the driver is on PATH from the bindings to SM, we need users to be able to explicitly tell SM to accept what is on the machine without downloading. I think ENV is the right way to do this.
