Cygwin: document the recent FIFO changes
2019-03-28 02:10:18 +08:00
What's new:
-----------
Cygwin: Add console patches to release notes Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2019-04-01 01:36:23 +08:00
- 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.
Cygwin: Implement sched_[gs]etaffinity() This patch set implements the Linux syscalls sched_getaffinity, sched_setaffinity, pthread_getaffinity_np, and pthread_setaffinity_np. Linux has a straightforward view of the cpu sets used in affinity masks. They are simply long (1024-bit) bit masks. This code emulates that view while internally dealing with Windows' distribution of available CPUs among processor groups.
2019-06-24 05:51:06 +08:00
- New APIs: sched_getaffinity, sched_setaffinity, pthread_getaffinity_np,
Cygwin: Implement CPU_SET(3) macros This patch supplies an implementation of the CPU_SET(3) processor affinity macros as documented on the relevant Linux man page. There is a mostly superset implementation of cpusets under newlib's libc/sys/RTEMS/include/sys that has Linux and FreeBSD compatibility and is built on top of FreeBSD bitsets. This Cygwin implementation and the RTEMS one could be combined if desired at some future point.

dbm_fetch, dbm_firstkey, dbm_nextkey, dbm_open, dbm_store.

Cygwin: add latest signal handling fixes to release notes Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2019-04-07 00:03:22 +08:00
- If a SA_SIGINFO signal handler changes the ucontext_t pointed to by
the third parameter, follow it after returning from the handler.
Rename <xlocale.h> back to <sys/_locale.h> libX11 provides <X11/Xlocale.h>. The build of libX11 itself adds include/X11 to the compiler's include path. This results in a name collision with /usr/include/xlocale.h on case-insensitive filesystems. Commit 90e35b1eb3df renamed sys/_locale.h to xlocale.h in March 2017 under the assumption that we should provide the locale_t type in the same file as on Linux, FreeBSD, and Darwin. A few weeks later (June 2017), glibc removed the xlocale.h file in favor of bits/types/locale_t.h, which shouldn't be included directly anyway. For reference and the reasoning, see https://sourceware.org/git/?p=glibc.git;a=commit;h=f0be25b6336d Given the above, revert 90e35b1eb3df4070e68afc5e7060665214d586be and fix additional usage of xlocale.h.
2019-06-13 04:31:14 +08:00
- Eliminate a header file name collision with <X11/XLocale.h> on case
insensitive filesystems by reverting <xlocale.h> back to <sys/_locale.h>.

Bug Fixes
---------
Cygwin: Add console patches to release notes Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2019-04-01 01:36:23 +08:00
- 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.
Cygwin: define MSG_EOR and refuse in send(2) Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2019-04-26 00:49:32 +08:00
- 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.
Cygwin: timerfd: avoid a deadlock Add a function timerfd_tracker::enter_critical_section_cancelable, which is like enter_critical_section but honors a cancel event. Call this when a timer expires while the timerfd thread is in its inner loop. This avoids a deadlock if timerfd_tracker::dtor has entered its critical section and is trying to cancel the thread. See https://cygwin.com/ml/cygwin/2019-06/msg00096.html.

Cygwin: sigpending: don't report pending signals for other threads The sigpending mechanism failed to check if the pending signal was a process-wide signal, or a signal for the curent thread. Fix that by adding a matching conditional to wait_sig's __SIGPENDING code. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2019-07-12 23:18:48 +08:00
- Fix sigpending() incorrectly returning signals for unrelated threads.
