+// When a Context is created it performs the complicated steps necessary to

+// delayed until this initialization is complete.  They are then allow to
+// execute on any specified thread.  Once all references to the Context are
+// gone, then the steps necessary to release the QuotaManager are performed.
+// After initialization the Context holds a self reference, so it will stay
+// alive until one of three conditions occur:
+//
+//  1) The Manager will call Context::AllowToClose() when all of the actors
+//     have removed themselves as listener.  This means an idle context with
+//     no active DOM objects will close gracefully.
+//  2) The QuotaManager aborts all operations so it can delete the files.
+//     In this case the QuotaManager calls Client::AbortOperationsForLocks()
+//     which in turn cancels all existing Action objects and then marks the
+//     Manager as invalid.
+//  3) Browser shutdown occurs and the Manager calls Context::CancelAll().
+//
+// In either case, though, the Action objects must be destroyed first to
+// allow the Context to be destroyed.
+//
+// While the Context performs operations asynchronously on threads, all of
+// methods in its public interface must be called on the same thread
+// originally used to create the Context.

+// ## 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.

+// represent named Cache objects.  There are cases, however, where

+// has been run.

+//
+// There should be exactly one Manager object for each origin or app using the
+// Cache API.  This uniqueness is defined by the ManagerId equality operator.
+// The uniqueness is enforced by the Manager GetOrCreate() factory method.
+//
+// The life cycle of Manager objects is somewhat complex.  While code may
+// hold a strong reference to the Manager, it will invalidate itself once it
+// believes it has become completely idle.  This is currently determined when
+// all of the following conditions occur:
+//
+//  1) There are no more Manager::Listener objects registered with the Manager
+//     by performing a Cache or Storage operation.
+//  2) There are no more CacheId references noted via Manager::AddRefCacheId().
+//  3) There are no more BodyId references noted via Manager::AddRefBodyId().
+//
+// In order to keep your Manager alive you should perform an operation to set
+// 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.
+//
+// As an invariant, all Manager objects must cease all IO before shutdown.  This
+// is enforced by the Manager::Factory.  If content still holds references to
+// Cache DOM objects during shutdown, then all operations will begin rejecting.

+// This test is mainly to verify that we are able to recover from a situation

+// 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:
