/** * The following functions are used to access the directory padding file. The * directory padding file lives in DOM Cache base directory * (e.g. foo.com/cache/.padding). It is used to keep the current overall padding * size for an origin, so that the QuotaManager doesn't need to access the * database when getting quota clients' usage. * * For the directory padding file, it's only accessed on Quota IO thread * (for getting current usage) and Cache IO threads (for tracking padding size * change). Besides, the padding file is protected by a mutex lock held by * CacheQuotaClient. * * Each padding file should only take 8 bytes (int64_t) to record the overall * padding size. Besides, we use the temporary padding file to indicate if the * previous action is completed successfully. If the temporary file exists, it * represents that the previous action is failed and the content of padding file * cannot be trusted, and we need to restore the padding file from the database.
