. 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.
Use JSON in debug serializer output unless it fails due to e.g. cyclic
values, in which case use toSource.
Disable file stats code by default, since its output isn't used.
This was SVN commit r8975.
