. completely rewrite waio - use IOCP, add several hardcore optimizations. now outperforms the AS SSD and ATTO benchmarks when writing . refactor file interface - use LIO_READ instead of 'r', allow access to file descriptor. . completely rewrite the IO wrapper. now much more simple, less CPU overhead, adds support for pre-issue/post-completion hooks and preallocation. io::Run defaults to simple synchronous IO; use io::Parameters to get asynchronous. . add alignment.h with constants and Align() function template (more efficient than round_up for compile-time constants) . add UniqueRange - similar to C++0x unique_ptr (emulated for C++03), plus a built-in size. avoids expensive thread-safe reference counting in shared_ptr. cleanup: - move fat_time functions into archive_zip - remove no longer needed io_align and block_cache - reduce dependencies in sysdep/compiler (move parts to code_annotation.h) - move IOCP into separate file (reused by waio) This was SVN commit r9350.
