remove the disk cache
remove trim_cache disk job
remove zero-storage
mark default_storage_constructor as deprecated
remove storage_interface
remove file_pool and default_storage_constructor. update connection_tester to use disk_io_thread.
only ftruncate files once
optimize hashing, by running sha1 directly on the memory mapped file
use boost-multi_index in file_view_pool
remove flush_piece and flush_hashed, simplify job-fence logic, remove prep_read_job_impl
support noatime
split out mmap implementation into a .cpp file
support hashing of content in part files. wraps up new disk storage
remove flush_piece disk job
separate out store_buffer into its own class
pass session_settings into storage operations instead of assigning a pointer in the storage object
use unordered_map in store_buffer
add fopen-based disk io back-end for non-64 bit systems or systems without mmap
factor out open_mode_t into its own header
first stab at windows memory mapped files support
build all of boost for autotools
remove flag in async_read callback handler
remove old open_mode_t, preadv/readv and coalesce buffers
support sparse and no_cache file flags in mmap
Remove use of overlapped I/O because we're no longer doing any scatter/gather syscalls the use of overlapped is an unnecessary complication.
don't explicitly specify global read and write. On MINGW we need to use libtorrent::read and libtorrent::write instead of the MINGW provided ::read and ::write.
If the underlying file is empty then m_mapping is expected to be null.
It is the caller's responsibilty to notice that the region's size is
zero and not dereference it in that case.
Otherwise there is no good way for users of default_storage::open_file
to determine that the opened file is empty.
