* Implement last opened functionality Fixes https://github.com/cdr/code-server/issues/4619 * Fix test temp dirs not being cleaned up * Mock logger everywhere This suppresses all the error and debug output we generate which makes it hard to actually find which test has failed. It also gives us a standard way to test logging for the few places we do that. * Use separate data directories for unit test instances Exactly as we do for the e2e tests. * Add integration tests for vscode route * Make settings use --user-data-dir Without this test instances step on each other feet and they also clobber your own non-test settings. * Make redirects consistent They will preserve the trailing slash if there is one. * Remove compilation check If you do a regular non-watch build there are no compilation stats so this bricks VS Code in CI when running the unit tests. I am not sure how best to fix this for the case where you have a build that has not been packaged yet so I just removed it for now and added a message to check if VS Code is compiling when in dev mode. * Update code-server update endpoint name
