What's new:
|
|
-----------
|
|
|
|
- Add 24 bit color support using xterm compatibility mode in Windows 10
|
|
1703 or later. Add fake 24 bit color support for legacy console,
|
|
which uses the nearest color from 16 system colors.
|
|
|
|
- Support pseudo console in PTY. Pseudo console is a new feature
|
|
in Windows 10 1809, which provides console APIs on virtual
|
|
terminal. With this patch, native console applications can work
|
|
in PTYs such as mintty, ssh, gnu screen or tmux.
|
|
|
|
- New APIs: sched_getaffinity, sched_setaffinity, pthread_getaffinity_np,
|
|
pthread_setaffinity_np, plus CPU_SET macros.
|
|
|
|
- New APIs: dbm_clearerr, dbm_close, dbm_delete, dbm_dirfno, dbm_error,
|
|
dbm_fetch, dbm_firstkey, dbm_nextkey, dbm_open, dbm_store.

- If a SA_SIGINFO signal handler changes the ucontext_t pointed to by
|
|
the third parameter, follow it after returning from the handler.
|
|
|
|
- Eliminate a header file name collision with <X11/XLocale.h> on case
|
|
insensitive filesystems by reverting <xlocale.h> back to <sys/_locale.h>.
|
|
|
|
- Allow times(2) to have a NULL argument, as on Linux.

Bug Fixes
|
|
---------
|
|
|
|
- Fix select() on console in canonical mode. Return after one line is
|
|
completed, instead of when only one key is typed.
|
|
|
|
- Make console I/O functions thread-safe.
|
|
|
|
- Define missing MSG_EOR. It's unsupported by the underlying Winsock
|
|
layer so using it in send(2), sendto(2), or sendmsg(2) will return -1
|
|
with errno set to EOPNOTSUPP and recvmsg(2) will never return it.
|
|
|
|
- Fix a timerfd deadlock.
