+// After initialization the Context holds a self reference, so it will stay

+// ## Firefox 57 Cache API v25/v26/v27 Schema Hack Info
+// ### Overview
+// In Firefox 57 we introduced Cache API schema version 26 and Quota Manager
+// schema v3 to support tracking padding for opaque responses. Unfortunately,
+// Firefox 57 is a big release that may potentially result in users downgrading
+// to Firefox 56 due to 57 retiring add-ons. These schema changes have the
+// unfortunate side-effect of causing QuotaManager and all its clients to break
+// if the user downgrades to 56. In order to avoid making a bad situation
+// worse, we're now retrofitting 57 so that Firefox 56 won't freak out.
+//
+// ### Implementation
+// We're introducing a new schema version 27 that uses an on-disk schema version
+// of v25. We differentiate v25 from v27 by the presence of the column added
+// by v26. This translates to:
+// - v25: on-disk schema=25, no "response_padding_size" column in table
+// "entries".
+// - v26: on-disk schema=26, yes "response_padding_size" column in table
+// "entries".
+// - v27: on-disk schema=25, yes "response_padding_size" column in table
+// "entries".
+//
+// ### Fallout
+// Firefox 57 is happy because it sees schema 27 and everything is as it
+// expects.
+//
+// Firefox 56 non-DEBUG build is fine/happy, but DEBUG builds will not be.
+// - Our QuotaClient will invoke `NS_WARNING("Unknown Cache file found!");`
+// at QuotaManager init time. This is harmless but annoying and potentially
+// misleading.
+// - The DEBUG-only Validate() call will error out whenever an attempt is made
+// to open a DOM Cache database because it will notice the schema is broken
+// and there is no attempt at recovery.
+//

+// There should be exactly one Manager object for each origin or app using the

+// The uniqueness is enforced by the Manager GetOrCreate() factory method.

+// The life cycle of Manager objects is somewhat complex. While code may

+// 3) There are no more BodyId references noted via Manager::AddRefBodyId().

+// a Listener, call AddRefCacheId(), or call AddRefBodyId().
+//
+// Even once a Manager becomes invalid, however, it may still continue to
+// exist. This is allowed so that any in-progress Actions can gracefully
+// complete.

+// The function returns a promise which will get resolved once all tests

+// This test is mainly to verify that we are able to recover from a situation
+// in which the padding file and the padding column are missing during origin
+// initialization. This was originally reported in bug 1425146 comment 39.
+// The situation can be described as follows:
+// 1. A profile is used in FF57. The storage version is 2.1. There's no cache
+// storage for http://www.mozilla.org
+// 2. The same profile is used in FF56. The storage version is still 2.1 which
+// doesn't prevent storage system from working since minor upgrades are
+// backwards-compatible. The cache storage for http://www.mozilla.org is
+// created with schema version 25 (without any padding stuff).
+// 3. The profile is used in FF57 again. Zero padding files for existing cache
+// storages are not created because storage is already at version 2.1.
+// Storage is being initialized and a missing padding file triggers padding
+// size computation from the cache database with schema version 25. Since
+// the computation happens before any real DOM cache operation, the database
+// is not upgraded to schema version 26, so the padding column is missing.

+ // the storage database:
+ // - storage/default/http+++www.mozilla.org/cache
+ // - create_cache.js

+ // The file create_cache.js in the package was run locally, specifically it
+ // was temporarily added to xpcshell.ini and then executed:
+ // mach xpcshell-test --interactive dom/cache/test/xpcshell/create_cache.js
+ // Note: it must be executed in FF56 and it only creates the directory
+ // "storage/default/chrome/cache" and the file "storage.sqlite". To make it
+ // become the profile in the test, additional manual steps are needed.
+ // 1. Create "http+++www.mozilla.org" folder under the ""storage/default".
+ // 2. Copy the "cache" folder under the "storage/default/chrome" to
+ // "storage/default/http+++www.mozilla.org".
+ // 3. Remove the folder "storage/default/chrome"
+ // 4. Remove the folder "storage/temporary".
