Bug 192042 – [Win] listDirectory in FileSystemWin.cpp should not skip all directories

• Component: Platform
• Status: RESOLVED FIXED

[Christopher Reid]

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.

Does this allow us to unskip a test on Windows?

It appears so, all storage tests are currently skipped on wincairo and all indexeddb tests seem to fail that assert. I believe most indexeddb tests should be passing now, I'll run through storage tests and update the expectations.

The WinCairo bot seems to just be in bad shape. Guessing you compiled on wincairo so we can assume all is well.

Yeah, I'm not sure why WebKitTestRunner.exe would be in use on wincairo EWS
