/**
* The goal of this test is to prove that orphaned files are cleaned up during
* origin initialization. A file is orphaned when there's a file with zero size
* in the $dbName.files/journals directory and the file table in the database
* contains no records for given id. A file can become orphaned when we didn't
* have a chance to remove the file from disk during shutdown or the app just
* crashed.

// - storage/permanent/chrome

// The file create_db.js in the package was run locally, specifically it was
// temporarily added to xpcshell.ini and then executed:
// mach xpcshell-test --interactive dom/indexedDB/test/unit/create_db.js
// Note: to make it become the profile in the test, additional manual steps
// are needed.
// 1. Remove the file "storage/ls-archive.sqlite".
