This is part of a general effort to move all of Terraform's non-library
package surface under internal in order to reinforce that these are for
internal use within Terraform only.
If you were previously importing packages under this prefix into an
external codebase, you could pin to an earlier release tag as an interim
solution until you've make a plan to achieve the same functionality some
other way.
The upstream bug with opening a browser on Windows Subsystem for Linux
has been fixed, so this reverts our local patch for this. The approach
upstream adds fallback support for x-www-browser and www-browser if
xdg-open fails, and this fixes the problem on WSL.
This reverts commit 12e090ce48.
With the current implementation of terraform login, Windows Subsystem
for Linux fails to open a browser due to lack of support for xdg-open.
This commit reuses a fix from pkg/browser#8 which detects a WSL
environment and uses cmd.exe to open the URL instead.
For unit testing in particular we can't launch a real browser for testing,
so this indirection is primarily to allow us to substitute a mock when
testing a command that can launch a browser.
This includes a simple mock implementation that expects to interact with
a running web server directly.
