Stellt plattformweite C++-Basistypen, fehlersichere Ergebnistypen und deterministische Speicherpools bereit.

Das Modul core stellt die plattformweiten Basistypen, PMR-Speicherpools und asynchronen Synchronisationsprimitive Future und Promise für die AUTOSAR Adaptive Platform bereit (SWArchitecture S. 60, [SWS_CORE_00326]). Zur Erfüllung strenger Sicherheits- und Echtzeitanforderungen ersetzt der Summentyp Result<T, E> klassische Exceptions durch deterministische Rückgabewerte ([SWS_CORE_00751]). Bei irreparablen Systemfehlern gewährleistet die Fail-Fast-Funktion Abort() den unverzüglichen, kontrollierten Prozessabbruch ([SWS_CORE_00052]).

Das Modul core fungiert als Basis-Funktionscluster der AUTOSAR Adaptive Platform und stellt einheitliche Datenstrukturen, asynchrone Kommunikationsprimitive und Speichermanagement-Mechanismen für alle Plattformdienste und Anwendungen bereit (SWArchitecture S. 60). Um deterministische Abläufe und funktionale Sicherheit in POSIX-Betriebssystemumgebungen zu garantieren, ersetzt core konventionelle C++-Exceptions durch den typensicheren Ergebnistyp Result<T, E> und kontrolliert dynamische Speicherzuweisungen über polymorphe Allokatoren ([SWS_CORE_00041], [SWS_CORE_00751]).

Für die nebenläufige Synchronisation implementiert core das Zusammenspiel von Future und Promise ([SWS_CORE_00326], [SWS_CORE_00344]). Während der Erzeuger den Berechnungsstatus oder Fehler über das Promise bereitstellt, erlaubt Future dem Konsumenten sowohl zeitüberwachte Abfragen via wait_for() als auch reaktive Weiterleitungen mittels then() ([SWS_CORE_00329], [SWS_CORE_00331], TimeSynchronization S. 90).

Zur Vermeidung von Fragmentierung stellt das Modul Pool-Ressourcen wie SynchronizedPoolResource und UnsynchronizedPoolResource bereit, die Allokationen auf Chunks fester Größe beschränken ([SWS_CORE_00030], [SWS_CORE_00067], SWArchitecture S. 61). Tritt ein unüberwindbarer Fehlerzustand ein, erzwingt die Plattform über Abort() unter vorangehender Ausführung eines registrierten AbortHandler die sofortige Fail-Fast-Terminierung des Prozesses ([SWS_CORE_00051], [SWS_CORE_00052]).

Systemrolle und architektonische Basis von ara::core

Das Modul core bildet das fundamentale Fundament der AUTOSAR Adaptive Platform und stellt grundlegende Typdefinitionen, Speicherverwaltungsmechanismen sowie Basisschnittstellen für alle funktionalen Cluster und Adaptive Applications bereit (SWArchitecture S. 60). Im Gegensatz zu anwendungsspezifischen Diensten ist core prozesslokal ausgelegt und definiert die wesentlichen Abstraktionen, um portable, deterministische und ressourceneffiziente C++-Software innerhalb von POSIX-Betriebssystemumgebungen zu realisieren (SWArchitecture S. 36).

Architektonisch fungiert das Modul als standardisierte Schnittstelle zwischen den hardwarenahen Betriebssystemfunktionen und den höheren Schichten der Adaptive Platform (SWArchitecture S. 60). Hierbei adressiert core zentrale Anforderungen an funktionale Sicherheit (ASIL) und Echtzeitfähigkeit, indem es dynamische Speicherallokationen kontrollierbar macht und auf den flächendeckenden Einsatz von C++-Exceptions im regulären Kontrollfluss verzichtet ([SWS_CORE_00052], [SWS_CORE_00751]). Die Bereitstellung plattformweiter Basistypen verhindert proprietäre Insellösungen zwischen Middleware-Komponenten wie ara::com oder ara::ts (ARAComAPI S. 46, TimeSynchronization S. 90).

Asynchrone Kontroll- und Datenflüsse über Future und Promise

Für die nebenläufige und entkoppelte Interaktion implementiert ara::core das Erzeuger-Verbraucher-Muster mittels Promise und Future ([SWS_CORE_00326], [SWS_CORE_00341]). Ein Promise repräsentiert die schreibende Schnittstelle, über die ein asynchroner Worker oder ein Kommunikations-Skeleton das Ergebnis oder einen Fehler hinterlegt ([SWS_CORE_00345], [SWS_CORE_00353]). Das konsumierende Gegenstück bildet Future, welches den gemeinsamen Zustand (Shared State) überwacht und den typsicheren Zugriff auf den Rückgabewert kapselt (ARAComAPI S. 46, ARAComAPI S. 59).

Um ein Blockieren von Client-Threads zu vermeiden, stellt Future neben der synchronen, blockierenden Abfragefunktion get() ([SWS_CORE_00326]) zeitbeschränkte Warteoperationen bereit: wait_for() und wait_until() liefern einen Statusindikator vom Typ FutureStatus zurück ([SWS_CORE_00329], [SWS_CORE_00330], ARAComAPI S. 1). Über die Methode then() können Callbacks registriert werden, die bei Eintreffen des Ergebnisses automatisch ausgeführt werden; wahlweise lässt sich hierbei ein anwenderspezifischer Executor einbinden, um die Ausführung auf bestimmte Thread-Pools zu steuern ([SWS_CORE_00024], [SWS_CORE_00331], [SWS_CORE_00337]). Kopiervorgänge sind für Future und Promise explizit unterbunden, um exklusive Besitzverhältnisse sicherzustellen ([SWS_CORE_00334], [SWS_CORE_00350]).

Deterministisches Fehlermanagement: Result, ErrorCode und ErrorDomain

Ein Kernaspekt der sicherheitsgerichteten Programmierung in der Adaptive Platform ist die strikte Vermeidung unkontrollierter Exceptions im regulären Betrieb. ara::core::Result<T, E> fungiert als typensichere Summentyp-Kapselung, die entweder einen Erfolgs-Nutzlastwert vom Typ T oder ein Fehlerobjekt vom Typ E enthält ([SWS_CORE_00721], [SWS_CORE_00723], [SWS_CORE_00751]). Spezialisierungen existieren sowohl für Referenztypen Result<T&, E> als auch für rückgabewertlose Operationen Result<void, E> ([SWS_CORE_00821], [SWS_CORE_00908]).

Der enthaltene Zustand wird über HasValue() oder den expliziten Konvertierungsoperator operator bool() geprüft ([SWS_CORE_00751], [SWS_CORE_00752]). Der Zugriff auf Nutzdaten erfolgt über Value() oder operator*(), während Fehler über Error() abgefragt werden ([SWS_CORE_00755], [SWS_CORE_00757]). Zur funktionalen Weiterverarbeitung und Fehlerfortpflanzung stellt Result Methoden wie Bind(), ValueOr() und Resolve() bereit ([SWS_CORE_00761], [SWS_CORE_00768]). Fehler werden über ErrorCode modelliert, welcher einen numerischen Fehlercode CodeType mit einer eindeutigen Domänenkennung ErrorDomain sowie optionalen Diagnose-Zusatzdaten SupportDataType verknüpft ([SWS_CORE_00121], [SWS_CORE_00122], [SWS_CORE_00512]). Die Methode ValueOrThrow() existiert als Brücke für Umgebungen mit aktivierter Ausnahmebehandlung, löst jedoch im Fehlerfall die mit der Domäne verknüpfte Exception aus ([SWS_CORE_00154], [SWS_CORE_00766]).

Polymorphe Speicherverwaltung über Pool-Ressourcen

Dynamische Allokation auf dem Standard-Heap birgt Risiken bezüglich Nicht-Determinismus und Speicherfragmentierung. ara::core integriert daher ein Speichermanagement auf Basis polymorpher Speicherressourcen (PMR), angelehnt an das C++-NVI-Muster (Non-Virtual Interface) (SWArchitecture S. 61). Die Basisklasse MemoryResource deklariert die öffentlichen Schnittstellen allocate() und deallocate(), welche intern die rein virtuellen Methoden do_allocate() und do_deallocate() ansteuern ([SWS_CORE_00041], [SWS_CORE_00061]).

Für echtzeitkritische Allokationsmuster stehen spezialisierte Pool-Ressourcen zur Verfügung: SynchronizedPoolResource bietet threadsichere Allokationen aus vorkonfigurierten Chunks und Blockgrößen über PoolOptions ([SWS_CORE_00027], [SWS_CORE_00030]). Für strikt thread-lokale Verarbeitungsphasen ohne Synchronisations-Overhead dient UnsynchronizedPoolResource ([SWS_CORE_00046], [SWS_CORE_00067]). Über release() kann der gesamte allokierte Speicherbereich in einem einzigen Schritt an die vorgeschaltete upstream_resource() zurückgegeben werden, was Speicherlecks bei phasenorientierten Arbeitsabläufen wirksam unterbindet ([SWS_CORE_00037], [SWS_CORE_00038], [SWS_CORE_00065]).

Fundamentale Utility- und Container-Typen (Optional, Array, Vector, Map)

Zur Vermeidung von undefiniertem Verhalten und zur Sicherstellung klarer Semantik normiert core elementare Container und Hilfstypen. ara::core::Optional<T> repräsentiert Werte, die vorhanden sein können oder nicht, ohne auf unsichere Null-Pointer zurückgreifen zu müssen ([SWS_CORE_01103], [SWS_CORE_01104], ARAComAPI S. 1). Der Zustand wird über has_value() oder operator bool() abgefragt, während Zugriffe über value(), value_or() oder operator*() erfolgen ([SWS_CORE_01128], [SWS_CORE_01129], [SWS_CORE_01130], [SWS_CORE_01134]). Spezielle Referenzüberladungen Optional<T&> gestatten das sichere Halten optionaler Referenzen ([SWS_CORE_01151], [SWS_CORE_01167]).

Für Datenstrukturen mit fester Größe stellt das Modul Array<T, N> bereit, das direkte Indizierung über operator[], bereichsüberprüften Zugriff mittels at() sowie Standard-Iteratoren unterstützt ([SWS_CORE_01250], [SWS_CORE_01265], [SWS_CORE_01273]). Vergleichsoperatoren sind nach strikten Codierrichtlinien mit bool-Rückgaben und Exception-Sicherheit implementiert ([SWS_CORE_01290], CPP14Guidelines S. 241). Dynamisch wachsende Sequenzen und assoziative Container werden durch Vector<T, Allocator> und Map<Key, T, Compare, Allocator> abgedeckt ([SWS_CORE_01318], [SWS_CORE_01428]). Beide Typen akzeptieren konfigurierbare Allokatoren, sodass Allokationen nahtlos über die polymorphen MemoryResource-Pools abgewickelt werden können ([SWS_CORE_00066], [SWS_CORE_01303], [SWS_CORE_01406]).

Verhalten im Fehlerfall und Fail-Fast-Terminierung

Kann ein Prozess einen schwerwiegenden Fehlerzustand nicht sicher kompensieren, greift das Fail-Fast-Prinzip der Adaptive Platform (SWArchitecture S. 60). Über die Schnittstelle Abort() wird die unmittelbare, unkonditionierte Terminierung des laufenden Prozesses herbeigeführt ([SWS_CORE_00052]). Die Funktion ist als [[noreturn]] und noexcept deklariert, um sicherzustellen, dass keine Stack-Unwinding-Routinen oder Destruktoren inkorrekte Folgezustände erzeugen ([SWS_CORE_00052], SWArchitecture S. 36).

Um vor dem Beenden flüchtige Diagnoseinformationen zu sichern oder letzte Notfall-Logging-Aktionen auszuführen, können Anwendungen über SetAbortHandler() oder AddAbortHandler() anwenderspezifische Rückruffunktionen registrieren ([SWS_CORE_00050], [SWS_CORE_00051], [SWS_CORE_00054]). Ein registrierter Abort-Handler muss der Signatur void() noexcept genügen ([SWS_CORE_00053]). Nach Ausführung des Handlers erzwingt die Plattform die endgültige Beendigung des Prozesses, sodass kein Weiterlaufen in undefiniertem Speicherzustand möglich ist (SWArchitecture S. 60).

Weiterführende Detailbelege

Die Spezifikation von core im Release R25-11 stützt sich auf eine Reihe normativer Festlegungen und Architekturmodelle. Für das Prozess-Lifecycle- und Notaus-Verhalten sind Initialize(), Deinitialize() sowie Abort() und SetAbortHandler() konstitutiv ([SWS_CORE_00051], [SWS_CORE_00052], SWArchitecture S. 60). Das asynchrone Kommunikationsmodell stützt sich maßgeblich auf Future ([SWS_CORE_00326], [SWS_CORE_00329]) und Promise ([SWS_CORE_00344], [SWS_CORE_00345]), deren Zusammenspiel in anwendungsnahen Clustern wie ara::com und ara::ts verifiziert wird (ARAComAPI S. 46, TimeSynchronization S. 90).

Das fehlerfreie Daten- und Speichermanagement wird durch die Spezifikationen zu Result ([SWS_CORE_00751], [SWS_CORE_00766]), ErrorCode ([SWS_CORE_00512]) und den PMR-Speicherklassen SynchronizedPoolResource sowie UnsynchronizedPoolResource normiert ([SWS_CORE_00030], [SWS_CORE_00046], SWArchitecture S. 61). Ergänzend definieren Container- und Vergleichsrichtlinien die deterministische Datenhaltung in sicherheitskritischen Gesamtsystemen ([SWS_CORE_01103], [SWS_CORE_01250], [SWS_CORE_01318], CPP14Guidelines S. 241).
