            Bug ID: 192042
           Summary: [Win] listDirectory in FileSystemWin.cpp should not
                    skip all directories
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Platform
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: chris.reid at sony.com

ASSERT(diskUsage >= databaseFileSize); is failing in SQLiteIDBBackingStore.cpp with mozilla's indexdb demo https://mdn.mozillademos.org/en-US/docs/Web/API/IndexedDB_API/Using_IndexedDB$samples/Full_IndexedDB_example?revision=1436833

SQLiteIDBBackingStore.cpp:
>    uint64_t diskUsage = 0;
>    for (auto& directory : FileSystem::listDirectory(m_absoluteDatabaseDirectory, "*")) {
>        for (auto& file : FileSystem::listDirectory(directory, "*.sqlite3"_s))
>            diskUsage += SQLiteFileSystem::getDatabaseFileSize(file);
>    }
>    ASSERT(diskUsage >= databaseFileSize);

FileSystem::listDirectory(m_absoluteDatabaseDirectory, "*") doesn't return anything because windows' listDirectory implementation never returns any child directories.
So diskUsage is always 0 for this case.
