- Fix build with SDL <=2.0.3
SDL_GetGlobalMouseState was introduced in 2.0.4
(which doesn't support OSX 10.5 or older)
- Don't include execinfo.h on Mac OS X 10.4
This file isn't included in the 10.4 SDK
- Use custom typedef for PFNGLSTENCILOPSEPARATEPROC on OSX 10.4/10.5
because the system OpenGL headers for those versions don't have it
Added Sys_FreeClipboardData(char*) so I don't have to copy the string
from SDL_GetClipboardText() into a Mem_Alloc() buffer, but can just
do the right thing per platform, which in case of POSIX/SDL2 is
SDL_free().
SDL1.2 doesn't have clipboard support, otherwise I'd have removed all
platform-specific implementations and used SDL_Get/SetClipboardText()
everywhere (IIRC AROS only supports SDL1.2?)
idStr is used in both the main thread and the async sound thread, so
it should better be thread-safe.. idDynamicBlockAlloc is not.
Use realloc() and free() instead.
For some reason this caused a lot more crashes (due to inconsistencies
in the allocator's heap) with newer Linux distros (like XUbuntu 20.04)
and when using GCC9, while they rarely reproduced with GCC7 or on
XUbuntu 18.04
fixes#391
I'm gonna use it with libbacktrace - I'll need the path of the
executable before I can use idStr (and thus before I could call
Sys_GetPath(PATH_EXE, str)).
.. but only if the file exists.
It's ok if mods don't have their own DLL/.so, but if they do have one
and loading fails it's interesting why they failed (e.g. no access
rights, 64bit lib with 32bit executable or other way around, missing
symbols due to wrong libc version, ...)
The same should be done for Windows, but that's still TODO.
handling SIGTTIN/OU allows running Doom3 in the background (or even
sending it to the background with Ctrl-Z + bg) by disabling TTY input
(before it would get stuck when run in background without +set in_tty 0,
see #215)
While at it, I also added signal handlers for some common crash signals
(SIGILL, SIGABRT, SIGFPE, SIGSEGV) to print a backtrace before exiting
the game (partly based on Yamagi Quake II code).
Sometimes memory was allocated with new[] but freed with delete instead
of delete[], which is wrong.
And there were some small memory leaks, too.
Furtunately clang's AddressSanitizer detected all that so I could easily
fix it.
(There seem to be some more small memory leaks which are harder to fix,
though)
the problem was that the CVar was initialized from the commandline
*after* Posix_InitConsoleInput() is called, so it was too late.
common->StartupVariable() seems to be the right way to initialize a
CVar early.
Since we don't have our own signal handler anymore, those two
init functions can be merged into the existing Sys_Init(), which
is already called by common->Init().
This was only implemented with MSVC style asm.
Comments suggest that it was used to help catch invalid FOV calculations,
which were probably only happening with ancient compiler bugs.
New CVar "in_kbd" to set the layout for the keyboard. SDL 1.2
doesn't offer any way to determine it, and we need this feature
to use the same key for toggling the console independent of the
keyboard layout.
The old "in_nograb" from the Linux backend is still supported.
Don't include the lazy precompiled.h everywhere, only what's
required for the compilation unit.
platform.h needs to be included instead to provide all essential
defines and types.
All includes use the relative path to the neo or the game
specific root.
Move all idlib related includes from idlib/Lib.h to precompiled.h.
precompiled.h still exists for the MFC stuff in tools/.
Add some missing header guards.
Thread return types are different between platforms, and its
probably not a good idea to return something of a different size,
cast the callback and expect it to not crash.
