The 'arena' allocator does not take memory alignment into account, which
can result in crashes at -O3 with gcc 7.5 (presumably because of SSE
instructions).
This accounts for alignment issues, fixing the issue.
Also do various cleanup in lib/allocators.

This was SVN commit r24517.
replace array-of-pages data structure with demand-committed VM => allows
simple allocation of new resources without having to search for the
first free index. I suspect the cause of multiple reported bugs (refs
#860, #899, #915) was a race. Most issues are fixed, but the pool's
freelist also needs to be made thread-safe and lock-free. this has
performance and 64-bit portability implications, so I'll leave it for
later (Pool is due for some serious refactoring anyway).
please post a comment if this or similar issues persist.
This was SVN commit r9961.
lib_errors.cpp: replace with status.cpp, adapt to needs at work
wutil: fix runtime warning reported via feedback box
config: merge CONFIG_PARANOIA and !CONFIG_FINAL into
CONFIG_ENABLE_CHECKS
add openmp, pointer_typedefs.h
This was SVN commit r9410.
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.
major refactor of wfilesystem - remove gotos and workaround for FAT file
times
replace more round_up of constants with Align<>
remove old unused allocators (STL aligned, matrix, some shared_ptr)
move allocator utils into separate headers.
remove lockfree, wterminal
avoid testing __cplusplus
This was SVN commit r9361.
. 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.
mem_util: inline freelist functions to avoid needing an additional if()
in pool.cpp
pool: add comments clarifying the roles of PoolAllocator vs
RawPoolAllocator
wsdl: refactor (naming convention, determination of window style, reduce
forward decls)
This was SVN commit r7610.
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.
move all except user-specified config choices out of config.h and into
appropriate headers
CPU_IA32 -> ARCH_IA32
wsdl: disable use of ddraw (will soon be replaced by WMI)
use shared_ptr without namespace qualifier (it's in tr1)
debug_warn -> debug_assert(0)
LIB_API to allow building as DLL
smart pointers: reduce use of .get()
cache_adt: use map instead of hash_map (avoids needing a hashCompare
class). also remove spurious warning
code_annotation.h: better cassert implementation
move FPS measuring portion of timer.cpp into frequency_filter
move include of memory headers into mmgr.h (to avoid errors, we must
ensure they are included if mmgr is used)
posix_filesystem.h: move definition of mkdir to wfilesystem
stl: disable iterator checks in release mode
wmi: fix COM init bug, use smart pointers
wutil: add code to get DLL module handle (if compiled as such), add
WinScopedLock
timer: fix handling of raw ticks
This was SVN commit r5517.
