Video

  • cpearce landed FileBlockCache, which provides a temporary file you can do blocking reads from on any (non-main) thread, write to on the main thread with buffering so that the main thread doesn't block, and move blocks around on the main thread (with buffering and a helper thread so the main thread doesn't block). We're using this to avoid main-thread I/O from the media cache. May be useful elsewhere.
