* qapi: Change munging of CamelCase enum valuesEric Blake2015-12-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When munging enum values, the fact that we were passing the entire prefix + value through camel_to_upper() meant that enum values spelled with CamelCase could be turned into CAMEL_CASE. However, this provides a potential collision (both OneTwo and One-Two would munge into ONE_TWO) for enum types, when the same two names are valid side-by-side as QAPI member names. By changing the generation of enum constants to always be prefix + '_' + c_name(value, False).upper(), and ensuring that there are no case collisions (in the next patches), we no longer have to worry about names that would be distinct as QAPI members but collide as variant tag names, without having to think about what munging the heuristics in camel_to_upper() will actually perform on an enum value. Making the change will affect enums that did not follow coding conventions, using 'CamelCase' rather than desired 'lower-case'. Thankfully, there are only two culprits: InputButton and ErrorClass. We already tweaked ErrorClass to make it an alias of QapiErrorClass, where only the alias needs changing rather than the whole tree. So the bulk of this change is modifying INPUT_BUTTON_WHEEL_UP to the new INPUT_BUTTON_WHEELUP (and likewise for WHEELDOWN). That part of this commit may later need reverting if we rename the enum constants from 'WheelUp' to 'wheel-up' as part of moving x-input-send-event to a stable interface; but at least we have documentation bread crumbs in place to remind us (commit 513e7cd), and it matches the fact that SDL constants are also spelled SDL_BUTTON_WHEELUP.

* qapi: Don't let implicit enum MAX member collideEric Blake2015-12-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we guarantee the user doesn't have any enum values beginning with a single underscore, we can use that for our own purposes. Renaming ENUM_MAX to ENUM__MAX makes it obvious that the sentinel is generated. This patch was mostly generated by applying a temporary patch: |diff --git a/scripts/qapi.py b/scripts/qapi.py |index e6d014b..b862ec9 100644 |--- a/scripts/qapi.py |+++ b/scripts/qapi.py |@@ -1570,6 +1570,7 @@ const char *const %(c_name)s_lookup[] = { | max_index = c_enum_const(name, 'MAX', prefix) | ret += mcgen(''' | [%(max_index)s] = NULL, |+// %(max_index)s | }; | ''', | max_index=max_index) then running: $ cat qapi-{types,event}.c tests/test-qapi-types.c | sed -n 's,^// \(.*\)MAX,s|\1MAX|\1_MAX|g,p' > list $ git grep -l _MAX | xargs sed -i -f list The only things not generated are the changes in scripts/qapi.py.

* sdl2: fix crash in handle_windowevent() when restoring the screen sizeAlberto Garcia2015-06-091-0/+4
| | | | | | | | | | | | | The Ctrl-Alt-u keyboard shortcut restores the screen to its original size. In the SDL2 UI this is done by destroying the window and creating a new one. The old window emits SDL_WINDOWEVENT_HIDDEN when it's destroyed, but trying to call SDL_GetWindowFromID() from that event's window ID returns a null pointer. handle_windowevent() assumes that the pointer is never null so it results in a crash.

* sdl2: Work around SDL2 SDL_ShowWindow() bugMax Reitz2014-12-171-0/+10
| | | | | | | | | | | | | | | | | | | Apparently it is possible for X to send an event to a hidden SDL2 window, leading to SDL2 believing it is now shown. SDL2 will pass the SDL_WINDOWEVENT_SHOWN message to the application without actually showing the window; the problem is that the next SDL_ShowWindow() will be a no-op because SDL2 assumes the window is already shown. The correct way to react to SDL_WINDOWEVENT_SHOWN would be to clear scon->hidden (analogous for SDL_WINDOWEVENT_HIDDEN). However, due to the window not actually being shown, this will somehow not be correct after all. Therefore, just hide the window on SDL_WINDOWEVENT_SHOWN if it is supposed to be hidden (and analogous for SDL_WINDOWEVENT_HIDDEN).

* sdl2: Use correct sdl2_console for window eventsMax Reitz2014-12-171-2/+4
| | | | | | | | | | | | | | SDL_PollEvent() polls events for all windows; therefore, sdl2_poll_events() will poll the events for all windows and not only for the one identified by the given sdl2_console. This should be considered in handle_windowevent(): The window affected by the event is not necessarily the one identified by the sdl2_console object given to sdl2_poll_events(), but the one identified by ev->window.windowID.

* ui/sdl2 : initial port to SDL 2.0 (v2.0)Dave Airlie2014-03-051-0/+829
I've ported the SDL1.2 code over, and rewritten it to use the SDL2 interface. The biggest changes were in the input handling, where SDL2 has done a major overhaul, and I've had to include a generated translation file to get from SDL2 codes back to qemu compatible ones. I'm still not sure how the keyboard layout code works in qemu, so there may be further work if someone can point me a test case that works with SDL1.2 and doesn't with SDL2. Some SDL env vars we used to set are no longer used by SDL2, Windows, OSX support is untested, I don't think we can link to SDL1.2 and SDL2 at the same time, so I felt using --with-sdlabi=2.0 to select the new code should be fine, like how gtk does it. v1.1: fix keys in text console v1.2: fix shutdown, cleanups a bit of code, support ARGB cursor v2.0: merge the SDL multihead patch into this, g_new the number of consoles needed, wrap DCL inside per-console structure.
