From 3ebe41af1827a536e36d926007e1c7dd967c571c Mon Sep 17 00:00:00 2001 From: Chris Michael Date: Tue, 17 Mar 2015 15:49:09 -0400 Subject: [PATCH] evas-wayland-shm: Refactor Evas Wayland Shm Engine (Fix T2201) Summary: This patch set fixes the issue of Evas wayland shm engine causing crashes when resizing efl apps in the E wayland compositor. It refactors the evas engine to wait for release events on buffers, and hooks into frame callbacks so that release events will get triggered at the appropriate time. @fix Signed-off-by: Chris Michael --- src/Makefile_Evas.am | 6 +- src/modules/evas/engines/wayland_shm/evas_engine.c | 253 +++++----- src/modules/evas/engines/wayland_shm/evas_engine.h | 85 +++- src/modules/evas/engines/wayland_shm/evas_outbuf.c | 515 +++++++++++++++++++++ src/modules/evas/engines/wayland_shm/evas_shm.c | 477 +++++++++++++++++++ 5 files changed, 1189 insertions(+), 147 deletions(-) create mode 100644 src/modules/evas/engines/wayland_shm/evas_outbuf.c create mode 100644 src/modules/evas/engines/wayland_shm/evas_shm.c diff --git a/src/Makefile_Evas.am b/src/Makefile_Evas.am index cb79b49..af00028 100644 --- a/src/Makefile_Evas.am +++ b/src/Makefile_Evas.am @@ -1179,10 +1179,8 @@ WAYLAND_SHM_SOURCES = \ modules/evas/engines/wayland_shm/Evas_Engine_Wayland_Shm.h \ modules/evas/engines/wayland_shm/evas_engine.c \ modules/evas/engines/wayland_shm/evas_engine.h \ -modules/evas/engines/wayland_shm/evas_swapbuf.c \ -modules/evas/engines/wayland_shm/evas_swapbuf.h \ -modules/evas/engines/wayland_shm/evas_swapper.c \ -modules/evas/engines/wayland_shm/evas_swapper.h +modules/evas/engines/wayland_shm/evas_shm.c \ +modules/evas/engines/wayland_shm/evas_outbuf.c if EVAS_STATIC_BUILD_WAYLAND_SHM lib_evas_libevas_la_SOURCES += $(WAYLAND_SHM_SOURCES) lib_evas_libevas_la_CPPFLAGS += @evas_engine_wayland_shm_cflags@ diff --git a/src/modules/evas/engines/wayland_shm/evas_engine.c b/src/modules/evas/engines/wayland_shm/evas_engine.c index 21f4ef3..fd97de6 100644 --- a/src/modules/evas/engines/wayland_shm/evas_engine.c +++ b/src/modules/evas/engines/wayland_shm/evas_engine.c @@ -1,171 +1,156 @@ #include "evas_common_private.h" #include "evas_private.h" -#include "Evas_Engine_Wayland_Shm.h" +#ifdef EVAS_CSERVE2 +# include "evas_cs2_private.h" +#endif + #include "evas_engine.h" -#include "evas_swapbuf.h" -/* local structures */ -typedef struct _Render_Engine Render_Engine;
