Cygwin: console: Disable cons_master_thread in win32-input-mode When win32-input-mode (which is supported by Windows Termainal) is set by "\033[?9001h", cons_master_thread does not work properly and consumes larger and larger memory space. This is because sending event by WriteConsoleInput() is translated into the sequence that is used by win32-input-mode. Due to this behaviour, write-back of the INPUT_RECORDs does not work as expected. With this patch, cons_master_thread is disabled on win32-input-mode where the signal keys such as Ctrl-C, Ctrl-Z etc. never comes.

Cygwin: pipe: Fix a regression that raw_write() slows down After the commit 7f3c22532577, writing to pipe extremely slows down. This is because cygwait(select_sem, 10, cw_cancel) is called even when write operation is already completed. With this patch, the cygwait() is called only if the write operation is not completed. Addresses: https://cygwin.com/pipermail/cygwin/2024-August/256398.html Fixes: 7f3c22532577 ("Cygwin: pipe: handle signals explicitely in raw_write") Reported-by: Jim Reisert AD1C <jjreisert@alum.mit.edu> Reviewed-by: Corinna Vinschen <corinna@vinschen.de> Signed-off-by: Takashi Yano <takashi.yano@nifty.ne.jp> (cherry picked from commit f78009cb1ccf84cc343cf2441c76196461d87532)

cygwin: pread/pwrite: prevent EBADF error after fork() If the parent process has already used pread() or pwrite(), these functions fail with EBADF if used on the inherited fd. Ensure that fix_after_fork() is called to invalidate the prw_handle. This issue has been detected by 'stress-ng --pseek 1'.

Cygwin: timer_delete: Fix return value timer_delete() always returned failure. This issue has been detected by 'stress-ng --hrtimers 1'. Fixes: 229ea3f23c015 ("Cygwin: posix timers: reimplement using OS timer") Signed-off-by: Christian Franke <christian.franke@t-online.de>

- Fix timer_delete() return value which always indicated failure.
Cygwin: lockf: Fix adding a new lock over multiple locks Previously, adding a new lock by lockf() over multiple existing locks failed. This is due to a bug that lf_setlock() tries to create a lock that has already been created. This patch fixes the issue. Addresses: https://cygwin.com/pipermail/cygwin/2024-October/256528.html Fixes: a998dd705576 ("* flock.cc: Implement all advisory file locking here.")
