It +creates surface-ids for desktop-surfaces depending on the configuration +provided in "weston.ini". For more please refer to the reference +implementation in this commit. + +The only public interface available is the "id_agent_module_init" +function. It is responsible for initialization of structs and reading +the configuration. + +In the reference "weston.ini" two types of configurations can be found: + +[desktop-app] is used to configure a particular application. Therefore +the desired surface-id must be provided. Moreover "app-title" is the +title that is provided by the desktop application (xdg-protocol). +"app-id" behaves accordingly. Although both parameters can be set, it +is not mandatory. Finally at least one has to be set. + +[desktop-app-default] enables the id-agent to generate generic +surface-ids for unconfigured applications, e.g. for development. This +tag is optional. To generate the id an interval starting from +"default-surface-id" to "default-surface-id-max" is used. The id is +incremented until the interval is exceeded. + +In the function "get_id" a surface-id is assigned by means of the +configuration. It can be adjusted, if another behavior is desired. +In this plugin the parameters, that are described above, are evaluated. + +To use these patches please also apply the dedicated patches for +weston: https://github.com/mtey/weston/tree/xdg_support_ivi_id_agent +Since libweston-desktop is used to introduce desktop-surface support, +xdg-protocol is supported. + +Signed-off-by: Michael Teyfel <mteyfel@de.adit-jv.com> +--- + ivi-id-agent-modules/ivi-id-agent/CMakeLists.txt | 69 ++++ + .../ivi-id-agent/src/ivi-id-agent.c | 381 +++++++++++++++++++++ + ivi-id-agent-modules/ivi-id-agent/weston.ini.in | 20 ++ + 3 files changed, 470 insertions(+) + create mode 100644 ivi-id-agent-modules/ivi-id-agent/CMakeLists.txt + create mode 100644 ivi-id-agent-modules/ivi-id-agent/src/ivi-id-agent.c + create mode 100644 ivi-id-agent-modules/ivi-id-agent/weston.ini.in + +diff --git a/ivi-id-agent-modules/ivi-id-agent/CMakeLists.txt b/ivi-id-agent-modules/ivi-id-agent/CMakeLists.txt +new file mode 100644 +index 0000000..2def105 +--- /dev/null ++++ b/ivi-id-agent-modules/ivi-id-agent/CMakeLists.txt +@@ -0,0 +1,69 @@ ++############################################################################### ++# ++# Copyright (C) 2017 Advanced Driver Information Technology Joint Venture GmbH ++# ++# ++# Licensed under the Apache License, Version 2.0 (the "License"); ++# you may not use this file except in compliance with the License. ++# You may obtain a copy of the License at ++# ++# http://www.apache.org/licenses/LICENSE-2.0 ++# ++# Unless required by applicable law or agreed to in writing, software ++# distributed under the License is distributed on an "AS IS" BASIS, ++# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. ++# See the License for the specific language governing permissions and ++# limitations under the License. ++# ++############################################################################### ++ ++cmake_minimum_required (VERSION 2.6) ++ ++project(ivi-id-agent) ++ ++find_package(PkgConfig REQUIRED) ++pkg_check_modules(WAYLAND_SERVER wayland-server REQUIRED) ++pkg_check_modules(WESTON weston>=2.0.0 REQUIRED) ++pkg_check_modules(PIXMAN pixman-1 REQUIRED) ++pkg_check_modules(LIBWESTON_DESKTOP libweston-desktop-2 REQUIRED) ++ ++find_package(Threads REQUIRED) ++ ++include_directories( ++ src ++ ${WAYLAND_SERVER_INCLUDE_DIRS} ++ ${WESTON_INCLUDE_DIRS} ++ ${PIXMAN_INCLUDE_DIRS} ++) ++ ++link_directories( ++ ${WAYLAND_SERVER_LIBRARY_DIRS} ++ ${PIXMAN_LIBRARY_DIRS} ++) ++ ++ ++add_library(${PROJECT_NAME} MODULE ++ src/ivi-id-agent.c ++) ++ ++set_target_properties(${PROJECT_NAME} PROPERTIES PREFIX "") ++ ++add_dependencies(${PROJECT_NAME} ++ ${WAYLAND_SERVER_LIBRARIES} ++ ${PIXMAN_LIBRARIES} ++) ++ ++set(LIBS ++ ${LIBS} ++ ${WAYLAND_SERVER_LIBRARIES} ++ ${LIBWESTON_DESKTOP_LIBRARIES} ++) ++ ++set(CMAKE_C_LDFLAGS "-module -avoid-version") ++ ++target_link_libraries(${PROJECT_NAME} ${LIBS}) ++ ++install ( ++ TARGETS ${PROJECT_NAME} ++ LIBRARY DESTINATION lib${LIB_SUFFIX}/weston ++) +diff --git a/ivi-id-agent-modules/ivi-id-agent/src/ivi-id-agent.c b/ivi-id-agent-modules/ivi-id-agent/src/ivi-id-agent.c +new file mode 100644 +index 0000000..9bc115d +--- /dev/null ++++ b/ivi-id-agent-modules/ivi-id-agent/src/ivi-id-agent.c +@@ -0,0 +1,381 @@ ++/* ++ * Copyright (C) 2017 Advanced Driver Information Technology Joint Venture GmbH ++ * ++ * Permission to use, copy, modify, distribute, and sell this software and ++ * its documentation for any purpose is hereby granted without fee, provided ++ * that the above copyright notice appear in all copies and that both that ++ * copyright notice and this permission notice appear in supporting ++ * documentation, and that the name of the copyright holders not be used in ++ * advertising or publicity pertaining to distribution of the software ++ * without specific, written prior permission.
