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.

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: 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.

Cygwin: lockf: Make lockf() return ENOLCK when too many locks Previously, lockf() printed a warning message when the number of locks per file exceeds the limit (MAX_LOCKF_CNT). This patch makes lockf() return ENOLCK in that case rather than printing the warning message.

Cygwin: console: Inherit pcon hand over from parent pty There was a long-standing issue that pseudo console ownership could not hand over from the process whose ctty is /dev/cons* rather than /dev/pty*. This problem happens when a cygwin app starts non-cygwin app in a pty, then the non-cygwin app starts multiple cygwin apps, and the non-cygwin app ends before the second cygwin apps end. In this case, the stub process of the non-cygwin app hands over the ownership of pcon to one of the second cygwin apps, however, this app does not hand over the ownership of pcon to another second cygwin app. This is due to the fact that the hand-over feature is implemented only in fhandler_pty_slave but not in fhandler_console. With this patch, the second cygwin apps check if their console device is inside a pseudo console, and if so, it tries to hand over the ownership of the pseudo console to anther process that is attached to the same pseudo console.
