• Changes to ara::exec::ExecErrc
• Clarification on interaction between Platform Health Management and Execution Management

用語(terms)

Term	Description
Executable	Part of an Application. It consists of executable code (with exactly one entry point) created at integation time that can be deployed and installed on a Machine. An Application may consist of one or more Executables, each of which can be deployed to different Machines.process
Modelled Process	A Modelled Process is an instance of an Executable to be executed on a Machine and has a 1:1 association with the ARXML/Meta-Model element Process. This document also uses the term process (without the "modelled" prefix) to refer to the OS concept of a running process.
Reporting Process	A type of Modelled Process with an associated Executable where reportingBehavior is omitted ([TPS_MANI_01279]) or set to reportsExecutionState. A Reporting Process is expected to report its Execution State to Execution Management.
Non-reporting Process	A type of Modelled Process with an associated Executable where reportingBehavior set to doesNotReportExecutionState ([TPS_MANI_01279]). A Non-reporting Process is not expected to report its Execution State to Execution Management.
Companion Process	A type of Reporting Process that is associated with Non-reporting Process and used to determine when functionality expected from Non-reporting Process is available. Whenever functional dependencies on Non-reporting Processes exist, the integrator can configure proxy Execution Dependencies on the Companion Process and make the Companion Process kRunning reporting conditional on monitored Non-reporting Process.
Self-terminating Process	A type of Modelled Process that has terminationBehavior configured to processIsSelfTerminating. This type of Modelled Process is allowed to self initiate termination procedure (i.e. just terminate with exit status EXIT_SUCCESS), or wait for Execution Management to initiate termination procedure via SIGTERM.
Unexpected Self-termination	The event consumed by Execution Management when a Modelled Process terminates without justified reason, for example: - termination without prior request where terminationBehavior is configured to processIsNotSelfTerminating. - termination before reporting kRunning. Please note that every Unexpected Self-termination is also an Unexpected Termination, so requirements for the later apply here as well.
Unexpected Termination	The event consumed by Execution Management when a Modelled Process terminates with exit status other than 0 (EXIT_SUCCESS). Any kind of unhandled signal will result in an Unexpected Termination and thus a non 0 exit status.
Execution Dependency	Dependencies between Modelled Process instances can be configured to define a sequence for starting and terminating them.
Execution Management	The element of the AUTOSAR Adaptive Platform responsible for the ordered startup and shutdown of the AUTOSAR Adaptive Platform and Adaptive Applications.
State Management	The element defining modes of operation for AUTOSAR Adaptive Platform. It allows flexible definition of functions which are active on the platform at any given time.
Function Group	A Function Group is a set of Modelled Processes which need to be controlled consistently. Depending on the state of the Function Group, processes (related to the Modelled Processes) are started or terminated. Modelled Processes can belong to more than one Function Group State, but at exactly one Function Group (if a Modelled Process were allowed to be running at the same point in time in more than one Function Group then potential contradictions in the logic of the Function Group state transitions could cause errors, see Section 7.5.3). MachineFG is a Function Group with a predefined name, which is mainly used to control Machine lifecycle and processes of platform level Applications. Other Function Groups are sort of general purpose tools used (for example) to control processes of user level Applications.
Function Group State	The element of State Management that characterizes the current status of a set of (functionally coherent) user-level Applications. The set of Function Groups and their Function Group States are configured in the Execution Manifest.
Undefined Function Group State	Any state of a Function Group, which is not modelled. A Function Group is in an Undefined Function Group State during state transition, if a state transition failed or if an Unexpected Termination or Unexpected Self-termination happened.
Machine State	A state of Function Group "MachineFG" with some predefined states (Startup/Shutdown/Restart). This can term can refer to the current state ("The Machine State is ..."), to a specific state ("In Machine State Startup ..."), or to a set of states ("In Machine States Startup or Shutdown ...").
Time Determinism	The results of a calculation are guaranteed to be available before a given deadline.
Data Determinism	The results of a calculation only depend on the input data and are reproducible, assuming a given initial internal state.
Full Determinism	Combination of Time and Data Determinism. Communication Management
Execution Manifest	Manifest file to configure execution of an Adaptive Application. An Execution Manifest is created at integration time and deployed onto a Machine together with the Executable to which it is attached. It supports the integration of the Executable code and describes the configuration properties (startup parameters, resource group assignment etc.) of each process, i.e. started instance of that Executable.
Machine Manifest	Manifest file to configure a Machine. The Machine Manifest holds all configuration information which cannot be assigned to a specific Executable or process.
Operating System	Software responsible for managing processes on a Machine and for providing an interface to hardware resources.
ExecutionClient	Adaptive Application interface to Execution Management.
DeterministicClient	Adaptive Application interface to Execution Management to support control of the process-internal cycle, a deterministic worker pool, activation time stamps and random numbers.
StateClient	State Management interface to Execution Management to support Function Group State and Machine State management.
Platform Health Management	A Functional Cluster within the Adaptive Platform FoundationRecovery Action
Process State	Lifecycle state of a Modelled Process
Service Instance	Manifest Manifest file to configure Service usage of an Adaptive Application.
Trusted Platform	An execution platform supporting a continuous chain of trust from boot through to application. The trust chain ensures that all execution is both authenticated (that all code executed is from the claimed source) and subjected to integrity validation (that prevents tampered code/data from being executed).
DeterministicSyncMaster	A synchronization control point that receives the synchronization requests through a dedicated communication channel, for example ara::com, and sends the calculated cycle information for the next execution cycle to the connected DeterministicClients in the same domain.
Deterministic Random Numbers	A set of random numbers that follows a known sequence and thus the same set can be distributed (one at a time) to deterministic workers. Note that this does not mean that randomness is compromised as that relates to predictability of the sequence by an observer and not to the fact that the set is predefined.
