When all actions succeed control is granted, if one fail control acces is denied. - - Actions can either be: - + Invocation to an other binding API, either internal or external (eg: a policy service, Alsa UCM, ...) - + C routines from a user provider plugin (eg: policy routine, proprietary code, ...) - + Lua script function. Lua provides access to every AGL appfw functionalities and can be extended from C user provided plugins. - -## Installation - - Controler is a native part of AGL Advance Audio Framework but may be used independently with any other service or application binder. - - Dependencies: the only dependencies are audio-common for JSON-WRAP and Filescan-utils capabilities. - - Controler relies on Lua-5.3, when not needed Lua might be removed at compilation time. - -## Config - -Configuration is loaded dynamically during startup time. The controller scans CONTROL_CONFIG_PATH for a file corresponding to pattern -"onload-bindername-xxxxx.json". When controller runs within AAAA binder it searches for "onload-audio-xxxx.json". First file found in the path the loaded -any other files corresponding to the same pather are ignored and only generate a warning. - -Each bloc in the configuration file are defined with - * label: must be provided is used either for debugging or as input for the action (eg: signal name, control name, ...) - * info: optional used for documentation purpose only - -Note by default controller config search path is defined at compilation time, but path might be overloaded with CONTROL_CONFIG_PATH -environment variable. Setenv 'CONTROL_ONLOAD_PROFILE'=xxxx to overload 'onload-default-profile' initialisation sequence. - -### Config is organised in 4 sections: - - * metadata - * onload defines the set of action to be executed at startup time - * control defines the set of controls with corresponding actions - * event define the set of actions to be executed when receiving a given signal - -### Metadata - -As today matadata is only used for documentation purpose. - * label + version mandatory - * info optional - -### OnLoad section - -Defines startup time configuration. Onload may provide multiple initialisation profiles, each with a different label. - * label is mandatory. Label is used to select onload profile at initialisation through DispatchOneOnLoad("onload-label") API; - * info is optional - * plugin provides optional unique plugin name. Plugin should follow "onload-bindername-xxxxx.ctlso" patern - and are search into CONTROL_PLUGIN_PATH. When defined controller will execute user provided function context=CTLP_ONLOAD(label,version,info). - The context returned by this routine is provided back to any C routines call later by the controller. Note that Lua2C function - are prefix in Lua script with plugin label (eg: MyPlug: in following config sample) - * lua2c list of Lua commands shipped with provided plugin. - * require list of binding that should be initialised before the controller starts. Note that some listed requirer binding might be absent, - nevertheless any present binding from this list will be started before controller binding, missing ones generate a warning. - * action the list of action to execute during loadtime. Any failure in action will prevent controller binding from starting. - -### Control section - -Defines a list of controls that are accessible through (api="control", verb="request", control="control-label"). - - * label mandatory - * info optional - * permissions Cynara needed privileges to request this control (same as AppFw-V2) - * action the list of actions - -### Event section - -Defines a list of actions to be executed on event reception. Even can do anything a controller can (change state, -send back signal, ...) eg: if a controller subscribes to vehicule speed, then speed-event may ajust master-volume to speed. - - * label mandatory - * info optional - * action the list of actions - -### Actions Categories - -Controler support tree categories of actions. Each action return a status status where 0=success and 1=failure. - * AppFw API, Provides a generic model to request other bindings. Requested binding can be local (eg: ALSA/UCM) or - external (eg: vehicle signalling). - * api provides requested binding API name - * verb provides verb to requested binding - * args optionally provides a jsonc object for targeted binding API. Note that 'args' are statically defined - in JSON configuration file. Controler client may also provided its own arguments from the query list. Targeted - binding receives both arguments defined in the config file and the argument provided by controller client. - * C-API, when defined in the onload section, the plugin may provided C native API with CTLP-CAPI(apiname, label, args, query, context). - Plugin may also create Lua command with CTLP-Lua2C(LuaFuncName, label, args, query, context). Where args+query are JSONC object - and context the value return from CTLP_ONLOAD function. Any missing value is set to NULL. - * Lua-API, when compiled with Lua option, the controller support action defined directly in Lua script. During "onload" phase the - controller search in CONTROL_Lua_PATH file with pattern "onload-bindername-xxxx.lua". Any file corresponding to this pattern - is automatically loaded. Any function defined in those Lua script can be called through a controller action. Lua functions receive - three parameters (label, args, query). - -Note: Lua added functions systematically prefix. AGL standard AppFw functions are prefixed with AGL: (eg: AGL:notice(), AGL_success(), ...). -User Lua functions added though the plugin and CTLP_Lua2C are prefix with plugin label (eg: MyPlug:HelloWorld1). - -### Avaliable Application Framework Commands - -Each Lua AppFw commands should be prefixed by AFB: - - * AFB:notice ("format", arg1,... argn) LUA table are print directly as json string with '%s'. - AFB:error, AFB:warning, AFB:info, AFB:debug work on the same model. Printed message are limited to 512 characters. - - * AFB:service ('API', 'VERB', {query}, "Lua_Callback_Name", {context}) asynchronous call to an other binding. When empty query/context should be set to '{}' - and not to 'nil'. When 'nil' Lua does not send 'NULL' value but remove arguments to calling stack. WARNING:"Callback" - is the name of the callback as a string and not a pointer to the callback. (If someone as a solution to fix this, please - let me known). Callback is call as LUA "function Alsa_Get_Hal_CB (error, result, context)" where: - * error is a Boolean - * result is the full answer from AppFw (do not forget to extract response) - * context is a copy of the Lua table pas as argument (warning it's a copy not a pointer to original table) - - * error,result=AFB:servsync('API', 'VERB', {query}) Save as previous but for synchronous call. Note that Lua accept multiple - return. AFB:servsync return both the error message and the response as a Lua table. Like for AFB:service user should not - forget to extract response from result. - - * AFB:success(request, response) request is the opaque handle pass when Lua is called from (api="control", verb="docall"). - Response is a Lua table that will be return to client. - - * AFB:fail(request, response) same as for success. Note that LUA generate automatically the error code from Lua function name. - The response is tranformed to a json string before being return to client. - - * EventHandle=AFB:evtmake("MyEventName") Create an event and return the handle as an opaque handle. Note that due to a limitation - of json_object this opaque handle cannot be passed as argument in a callback context. - - * AFB:subscribe(request, MyEventHandle) Subscribe a given client to previously created event. - - * AFB:evtpush (MyEventHandle, MyEventData) Push an event to every subscribed client. MyEventData is a Lua table that will be - send as a json object to corresponding clients. - - * timerHandle=AFB:timerset (MyTimer, "Timer_Test_CB", context) Initialise a timer from MyTimer Lua table. This table should contend 3 elements: - MyTimer={[l"abel"]="MyTimerName", ["delay"]=timeoutInMs, ["count"]=nBOfCycles}. Note that is count==0 then timer is cycle - infinitively. Context is a standard Lua table. This function return an opaque handle to be use to further control the timer. - - * AFB:timerclear(timerHandle) Kill an existing timer. Return an error when timer does not exit. - - * MyTimer=AFB:timerget(timerHandle) Return Label, Delay and Count of an active timer. Return an error when timerHandle does not - point on an active timer. - -Note: Except for function call during binding initialisation period. Lua call are protected and should return clean message - even when improperly used. If you find bug please report. - -### Adding Lua command from User Plugin - -User Plugin is optional and may provide either native C-action accessible directly from controller actions as defined in -JSON config file, or alternatively may provide at set of Lua commands usable inside any script (onload, control,event). A simple -plugin that provide both natice C API and Lua commands is provided as example (see ctl-plugin-sample.c). Technically a -plugin is a simple sharelibrary and any code fitting in sharelib might be used as a plugin. Developer should nevertheless -not forget that except when no-concurrency flag was at binding construction time, any binding should to be thread safe. - -A plugin must be declare with CTLP_REGISTER("MyCtlSamplePlugin"). This entry point defines a special structure that is check -at plugin load time by the controller. Then you have an optional init routine declare with CTLP_ONLOAD(label, version, info). -This init routine receives controller onload profile as selected by DispatchOnLoad("profile"). The init routine may create -a plugin context that is later one presented to every plugin API this for both LUA and native C ones. Then each: - - * C API declare with CTLP_CAPI (MyCFunction, label, argsJ, queryJ, context) {your code}. Where: - * MyFunction is your function - * Label is a string containing the name of your function - * ArgsJ a json_object containing the argument attach the this control in JSON config file. - * context your C context as return from CTLP_ONLOAD - - * Lua API declarewith TLP_LUA2C (MyLuaCFunction, label, argsJ, context) {your code}. Where - * MyLuaCFunction is both the name of your C function and Lua command - * Label your function name as a string - * Args the arguments passed this time from Lua script and not from Json config file. - * Query is not provided as LuaC function are called from a script and not directly from controller action list. - -Warning: Lua samples use with controller enforce strict mode. As a result every variables should be declare either as -local or as global. Unfortunately "luac" is not smart enough to handle strict mode at build time and errors only appear -at run time. Because of this strict mode every global variables (which include functions) should be prefix by '_'. -Note that LUA require an initialisation value for every variables and declaring something like "local myvar" wont -allocate "myvar" - -### Debugging Facilities - -Controler Lua script are check for syntax from CMAKE template with Luac. When needed to go further an developer API allow to -execute directly Lua command within controller context from Rest/Ws (api=control, verb=lua_doscript). DoScript API takes two -other optional arguments func=xxxx where xxxx is the function to execute within Lua script and args a JSON object to provide -input parameter. When funcname is not given by default the controller try to execute middle filename doscript-xxxx-????.lua. - -When executed from controller Lua script may use any AppFw Apis as well as any L2C user defined commands in plugin. - -### Running as Standalone Controller - -Controller is a standard binding and can then be started independently of AAAA. When started with from build repository with -``` -afb-daemon --port=1234 --workdir=. --roothttp=../htdocs --tracereq=common --token= --verbose --binding=./Controller-afb/afb-control-afb.so -``` - -Afb-Daemon only load controller bindings without search for the other binding. In this case the name of the process is not change -to afb-audio and controller binding will search for a configuration file name 'onload-daemon-xxx.json'. This model can be used -to implement for testing purpose or simply to act as the glue in between a UI and other binder/services. - -## Config Sample - -Here after a simple configuration sample. - -``` -{ -
