Date: Sat, 5 Apr 2008 19:54:28 -0700 From: "Chris Peterson" To: sdl@lists.libsdl.org Subject: [SDL] [PATCH] SDLMain.m: fix a bug and some warnings for Mac OS X Here are some small fixes for the src/main/macosx/SDLMain.m source file used by Mac OS X apps: 1. setupWorkingDirectory() called chdir() within an assert(), which gets compiled out in non-debug builds. 2. When some of gcc's optional warnings are enabled, it complains about some implicit casts and the use of #import in SDLMain.m.

Don't recreate the GL content in windib target if SDL_SetVideoMode() is being called in response to a window resize event...prevents loss of GL state and objects.

We probably want to still do this for fullscreen surfaces, since we may be clearing the edges of a centered video mode or garbage left over from a mode switch.

Date: Thu, 28 Feb 2008 22:54:29 +0100 From: Sylvain Beucler Subject: [SDL] SDL window resize and flicker I have a resizable SDL window, and when it's resized, the surface goes black _and_ is flushed to screen before I have a chance to redraw it. This causes flicker. The super-small attached patch fixes this issue by avoiding a SDL_Flip() right after the window resize. What do you think? This SDL_ClearSurface function is only called once in the code, in SDL_SetVideoMode, and as far as I can tell the patch doesn't introduce other changes than getting rid of the flicker.
Fri, 29 Feb 2008 13:55:44 +0000 * Added configure option --enable-screensaver, to allow enabling the screensaver by default. SDL-1.2
Sam Lantinga <slouken@libsdl.org> [Fri, 29 Feb 2008 13:55:44 +0000] rev 4139
* Added configure option --enable-screensaver, to allow enabling the screensaver by default. * Use XResetScreenSaver() instead of disabling screensaver entirely. Full discussion summary from Erik on the SDL mailing list: Current behaviour ================= SDL changes the user's display power management settings without permission from the user and without telling the user. The interface that it uses to do so is DPMSDisable/DPMSEnable, which should only ever be used by configuration utilities like KControl, never by normal application programs, let alone by the libraries that they use. Using an interface that is not at all intended for what SDL tries to achieve means that it will not work as it should. Firstly, the power management is completely disabled during the whole lifetime of the SDL program, not only when it should be. Secondly, it makes SDL non-reentrant, meaning that things will break when multiple SDL programs are clients of the same X server simultaneously. Thirdly, no cleanup mechanism ensures that the setting is restored if the client does not do that (for example if it crashes). In addition to that, this interface is broken on xorg, [http://bugs.freedesktop.org/show_bug.cgi?id=13962], so what SDL tries to do does not work at all on that implementation of the X Window System. (The reason that the DPMSEnable works in KControl is that it calls DPMSSetTimeout immediately after, [http://websvn.kde.org/tags/KDE/3.5.9/kdebase/kcontrol/energy/energy.cpp?annotate=774532#l343]). The problems that the current behaviour causes ============================================== 1. Information leak. When the user is away, someone might see what the user has on the display when the user counts on the screensaver preventing this. This does not even require physical access to the workstation, it is enough to see it from a distance. 2. Draining battery. An SDL program that runs on a laptop will quickly drain the battery while the user is away. The system will soon shut down and require recharging before being usable again, while it should in fact have consumed very little energy if the user's settings would have been obeyed. 3. Wasting energy. Even if battery issues are not considered, energy as such is wasted. 4. Display wear. The display may be worn out. The problems that the current behaviour tries to solve ====================================================== 1. Preventing screensaver while playing movies. Many SDL applications are media players. They have reasons to prevent screensavers from being activated while a movie is being played. When a user clicks on the play button it can be interpreted as saying "play this movie, but do not turn off the display while playing it, because I will watch it even though I do not interact with the system". 2. Preventing screensaver when some input bypasses X. Sometimes SDL uses input from another source than the X server, so that the X server is bypassed. This obviously breaks the screensaver handling. SDL tries to work around that. 3. Preventing screensaver when all input bypasses X. There is something called Direct Graphics Access mode, where a program takes control of both the display and the input devices from the X server. This obviously means that the X server can not handle the screensaver alone, since screensaver handling depends on input handling. SDL does not do what it should to help the X server to handle the screensaver. Nor does SDL take care of screeensaver handling itself. SDL simply disables the screensaver completely. How the problems should be solved ================================= The correct way for an application program to prevent the screensaver under X is to call XResetScreenSaver. This was recently discovered and implemented by the mplayer developers, [http://svn.mplayerhq.hu/mplayer?view=rev&revision=25637]. SDL needs to wrap this in an API call (SDL_ResetScreenSaver) and implement it for the other video targets (if they do not have a corresponding call, SDL should do what it takes on that particular target, for example sending fake key events). 1. When a movie is played, the player should reset the screensaver when the animation is advanced to a new frame. The same applies to anything similar, like slideshows. 2. When the X server is handling input, it must handle all input (keyboards, mice, gamepads, ...). This is necessary, not only to be able to handle the screensaver, but also so that it can send the events to the correct (the currently active) client. If there is an input device that the X server can not handle for some reason (such as lack of Plug and Play capability), the program that handles the device as a workaround must simulate what would happen if the X server would have handled the device, by calling XResetScreenSaver when input is received from the device. 3. When the X server is not handling the input, it depends on the program that does to call XResetScreenSaver whenever an input event occurs. Alternatively the program must handle the screensaver countdown internally and call XActivateScreenSaver.

Date: Tue, 05 Feb 2008 01:41:08 -0500 From: Mike Miscevic Subject: SDL and capslock/numlock Find attached a patch against SDL-1.2.13 for check of SDL_NO_LOCK_KEYS environment variable. This differs slightly from other patches I've seen in that it has 3 modes: Disable CAPS-LOCK and NUM-LOCK supression of down+up key events, suitable for games where the player needs these keys to do more than just toggle. A value of 1 will effect both CAPS-LOCK and NUM-LOCK. A value of 2 will effect only CAPS-LOCK. A value of 3 will effect only NUM-LOCK. All other values have no effect. This works for me and has been tested on: - Fedora 8 64-bit - SRCRPM SDL-1.2.13-1.fc8.src.rpm - Emeny Territory Quake Wars (ETQW), native 32-bit commercial game --Mike Miscevic
