the old debug_assert always ran and tested the expression, which slows
down release builds. wrapping them in #ifndef NDEBUG is clumsy. the new
ASSERT behaves like assert and ENSURE like the old debug_assert. Let's
change any time-critical but not-super-important ENSURE to ASSERT to
speed up release builds. (already done in bits.h and unique_range.h)
This was SVN commit r9362.
. 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.
CAS: uintptr_t->intptr_t to allow use of both cpu_CAS and cpu_AtomicAdd
topology: remove non-thread safe caching, expose ApicIds, use ModuleInit
x86_x64: use ModuleInit instead of unsafe static flags; zero-init regs
instead of just setting ecx
ModuleInitState now holds the LibError returned by the init callback (so
that the second init doesn't appear to succeed despite the first
failing)
wnuma: cleanup, add ACPI SLIT relative distance detection
This was SVN commit r7741.
also rename wchar -> utf8 to avoid conflict with <wchar.h> (requires
rebuild of workspace)
(unfortunately copying history fails to "502 bad gateway"; had to delete
old + add new independently)
This was SVN commit r7340.
also improved filtering of the frame delta times.
while at it, improved interface of whrt backends to avoid leaking
implementation details.
This was SVN commit r6401.
