#ifdef G_OS_WIN32

Add g_system_thread_set_name() implementation for W32 threads This works by using semi-documented[1] exception to tell the debugger that a thread needs to have its name changed. If this exception is not caught and handled by something, it will crash the process, so we need to set up our own handler in case there's no debugger attached or the debugger can't handle this type of exception. Since SEH is not supported by gcc on i686 (at the moment), we need to use VEH instead. For completeness the MSVC-oriented code still uses SEH, although there is no reason why it shouldn't work with the VEH variant used by MinGW. VEH handler has to be set up somewhere (g_thread_win32_init () works nicely) and removed once it's not needed (g_thread_win32_process_detach () is added expressly for that purpose). Note that g_thread_win32_process_detach() is only called when glib is unloaded by FreeLibrary(), not when glib-using process is terminating. This exception is known to work with WinDbg, and adding support for it into GDB proved to be feasible (GDB patch will be sent upstream, eventually).

W32: add std stream redirection envvar options This commit adds two W32-only environmental variable checks: * G_WIN32_ALLOC_CONSOLE, if set to 1, will force glib to create a new console if the process has no console by itself. This option is for GUI apps that are launched from GUI processes, in which case there's no console anywhere near them. * G_WIN32_ATTACH_CONSOLE, if set to a comma-separated list of standard stream names (stdint, stdout, stderr), will reopen a given std stream and tie it to the console (using existing console or parent console). This works either with the other option (to create a console), or if the app is launched from a console process (often the case for developers). The redirection is done with freopen(), dup() and dup2(). If everything goes well, C file descriptors 0, 1 or 2 will be bound to stdin, stdout and stderr respectively (only for streams listed in the envrionmental variable), and so will be stdio streams by the same names. With these it's possible to see the output of g_log*() functions when running GTK4 applications, which are linked as GUI applications, and thus do not get a console by default. https://bugzilla.gnome.org/show_bug.cgi?id=790857 Fixes issue #1304

W32: Add a simple exception handler Install a Vectored Exception Handler[0]. Its sole purpose is to catch some exceptions (access violations, stack overflows, illegal instructions and debug breaks - by default, but it can be made to catch any exception for which a code is known) and run a debugger in response. This allows W32 glib applications to be run without a debugger, but at the same time allows a debugger to be attached in case something happens. The debugger is run with a new console, unless an environment variable is set to allow it to inherit the console of the crashing process. The short list of handleable exceptions is there to ensure that this handler won't run a debugger to "handle" utility exceptions, such as the one that is used to communicate thread names to a debugger. The handler is installed to be called last, and shouldn't interfere with any user-installed handlers. There's nothing fancy about the way it runs a debugger (it doesn't even support unicode in paths), and it deliberately avoids using glib code. The handler will also print a bit of information about the exception that it caught, and even more information for well-known exceptions, such as access violation. The whole scheme is similar to AeDebug[1] and, in fact, the signal-event gdb command was originally implemented for this very purpose.

gwin32.c: Split out call to RtlGetVersion() Unfortunately, we may well be likely to need to call RtlGetVersion() via GetModuleHandle() + GetProcAddress(), so split out the call to RtlGetVersion() into a private function of its own, so that we can reuse the same code in other parts of GLib, so that we can: * Determine better in a more fine-tuned way to determine whether we are on Windows 10/11 and/or Server 2016/2019/2022, since we need to rely on the build number. * Just call RtlGetVersion() once, when needed, as that is all that is needed. We could re-use the same function once to compare what we got when we called RtlGetVersion() and do what is necessary there.

Fix process spawning with static build on Windows On Windows, process spawning needs an external helper exe which is found relatively to the glib DLL file. If glib has been built statically this file doesn't exist anymore and reference path is not the DLL path anymore but the current executable path. This patch searches for the helper exe taking as starting point the current executable path, relative 'bin', 'lib', 'glib' and 'gio' folders and then gets one level up until the root path. If this search doesn't give result then the helper exe is searched using the PATH variable.
