Cygwin: FILE_OPEN_NO_RECALL is incompatible with FILE_DIRECTORY_FILE If FILE_DIRECTORY_FILE is given, FILE_OPEN_NO_RECALL is not allowed, otherwise NtCreateFile returns STATUS_INVALID_PARAMETER. Drop FILE_OPEN_NO_RECALL where FILE_DIRECTORY_FILE is specified.

Fixes:
------
- Fix regression in 3.5.3 which fails to open files for stat(2) if the
file is opened exclusively by another process.

Cygwin: globify: read full 32 bit character While commit 0321fb573654 ("Cygwin: glob: convert wchar_t to wint_t") switched the entire glob mechanism from wchar_t to wint_t, the globify function calling glob on a DOS command line did not catch up and only checked for the next character constituting a 16 bit wchar_t. This broke reading surrogate pairs from incoming DOS command lines if the string had to go through glob(3). Check for an entire 32 bit unicode char instead.

- Fix regression introduced in 3.5.0 when reading surrogate pairs (i.e.,
unicode chars >= 0x10000) from the DOS command line. Addresses:

Cygwin: pthread: Fix a race issue introduced by the commit 2c5433e5da82 To avoid race issues, pthread::once() uses pthread_mutex. This caused the handle leak which was fixed by the commit 2c5433e5da82. However, this fix introduced another race issue, i.e., the mutex may be used after it is destroyed. This patch fixes the issue. Special thanks to Bruno Haible for discussing how to fix this.

Cygwin: disable high-entropy VA for ldh If ldd is run against a DLL which links to the Cygwin DLL, ldh will end up loading the Cygwin DLL dynamically, much like cygcheck or strace.

Cygwin: pty: Avoid client deadlock when pty master stops to read. Previsouly, the following commands hangs: mintty -e timeout 1 dash -c 'yes aaaaaaaaaaaaaaaaaaaaaaaaa | cat' The mechanism is as follows. When the child process (timeout) is terminated, mintty seems to stop reading pty master even if yes or cat still alive. If the the pipe used to transfer output from pty slave to pty master is full due to lack of master reader, WriteFile() to the pipe is blocked. WriteFile() cannot be canceled by cygwin signal, therefore, pty slave hangs. This patch avoids hanging by checking pipe space before calling WriteFile() and prevents writing data more than space.

Cygwin: console: Fix conflict on shared names between sessions. Previously, shared names in the console were created using get_minor(). However, get_minor() was not unique to the console across sessions. This is because EnumWindows(), which is used to look for console windows, cannot enumerate windows across sessions. This causes conflict on the shared names between sessions (e.g. sessions of different users, different services, a service and a user session, etc.). With this patch, GetConsoleWindow() is used instead of get_minor(). GetConsoleWindow() has been used for the name of shared memory, which should be unique to each console.
