dbb8069df5 Cygwin: check_dir_not_empty: Avoid leaving the allocated buffer.
The pointer pfni gets allocated the buffer at the begin,
and is used in the NtQueryDirectoryFile call before the loops.
In the loop the pointer pfni is also used as iterator.
Therefore it holds no longer the initial buffer at the call
to NtQueryDirectoryFile in the while conditition at the bottom.

1e8c92e21d Cygwin: Change pthread_sigqueue() to accept thread id
Change the first parameter of pthread_sigqueue() to be a thread id rather
than a thread pointer. The change is to match the Linux implementation of
this function.

The user-visible function prototype is changed in include/pthread.h.
The pthread_sigqueue() function is modified to work with a passed-in thread
id rather than an indirect thread pointer as before.  (It used to be
"pthread_t *thread", i.e., class pthread **.)  The release note for Cygwin
3.5.5 is updated.

04f386e9af 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.

ae181b0ff1 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.

f9cc21dc00 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.

If the parent process has already used pread() or pwrite(), these

fix_after_fork() is called to invalidate the prw_handle.  This issue

f78009cb1c 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.

84d77e5918 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.
