From dffbb9c4567e9d29d19964a83129e38dceab7055 Mon Sep 17 00:00:00 2001 From: Jeff Sharkey Date: Thu, 30 Jan 2014 15:01:39 -0800 Subject: Many improvements to download storage management. Change all data transfer to occur through FileDescriptors instead of relying on local files. This paves the way for downloading directly to content:// Uris in the future. Rewrite storage management logic to preflight download when size is known. If enough space is found, immediately reserve the space with fallocate(), advising the kernel block allocator to try giving us a contiguous block regions to reduce fragmentation. When preflighting on internal storage or emulated external storage, ask PackageManager to clear private app caches to free up space. Since we fallocate() the entire file, use the database as the source of truth for resume locations, which requires that we fsync() before each database update. Store in-progress downloads in separate directories to keep the OS from deleting out from under us. Clean up filename generation logic to break ties in this new dual-directory case. Clearer enforcement of successful download preconditions around content lengths and ETags. Move all database field mutations to clearer DownloadInfoDelta object, and write back through single code path. Catch and log uncaught exceptions from DownloadThread. Tests to verify new storage behaviors. Fixed existing test to reflect correct RFC behavior.
