Shinnick). + - support a max_idle value of 0. + - support setting of idle timeout value (eio_set_idle_timeout). + - readdir: correctly handle malloc failures. + - readdir: new flags argument, can return inode + and possibly filetype, can sort in various ways. + - readdir: stop immediately when cancelled, do + not continue reading the directory. + - fix return value of eio_sendfile_sync. + - include sys/mman.h for msync. - added EIO_STACKSIZE. - added msync, mtouch support (untested). - added sync_file_range (untested). - fixed custom support. - use a more robust feed-add detection method. - "outbundled" from IO::AIO. + - eio_set_max_polltime did not properly convert time to ticks. + - tentatively support darwin in sendfile. + - fix freebsd/darwin sendfile. + - also use sendfile emulation for ENOTSUP and EOPNOTSUPP + error codes. + - add OS-independent EIO_MT_* and EIO_MS_* flag enums. + - add eio_statvfs/eio_fstatvfs. + - add eio_mlock/eio_mlockall and OS-independent MCL_* flag enums. + - no longer set errno to 0 before making syscalls, this only lures + people into the trap of believing errno shows success or failure. + - "fix" demo.c so that it works as non-root. + - suppoert utimes seperately from futimes, as some systems have + utimes but not futimes. + - use _POSIX_MEMLOCK_RANGE for mlock. + - do not (errornously) overwrite CFLAGS in configure.ac. + - mknod used int3 for dev_t (ยง2 bit), not offs (64 bit). + - fix memory corruption in eio_readdirx for the flags + combination EIO_READDIR_STAT_ORDER | EIO_READDIR_DIRS_FIRST. + - port to openbsd (another blatantly broken non-UNIX/POSIX platform). + - fix eio_custom prototype. + - work around a Linux (and likely FreeBSD and other kernels) bug + where sendfile would not transfer all the requested bytes on + large transfers, using a heuristic. + - use libecb, and apply lots of minor space optimisations. + - disable sendfile on darwin, broken as everything else. + - add realpath request and implementation. + - cancelled requests will still invoke their request callbacks. + - add fallocate. + - do not acquire any locks when forking. + - incorporated some mingw32 changes by traviscline. + - added syncfs support, using direct syscall. + - set thread name on linux (ps -L/Hcx, top, gdb). + - remove useless use of volatile variables. + - fix memory leak when reaping threads. + - use utime now uses nanosecond resolution on posix 2008 systems. + - allow taking advantage of posix 2008 xxxat functions and fdopendir + by implementing a working directory abstraction. + - make readahead emulation behave more like actual readahead by never failing.
