Each HAL could + * then be versioned (class HAL_V1, class HAL_V2, etc) and inherit from a base class HAL. + * Then the version number in this function could be used to decide which one to return + * (if any). + * + * IPACM does not need to talk directly back to the returned HAL class. The other methods that + * IPACM needs to call are covered by registering the event listeners. If IPACM did need to + * talk directly back to the HAL object, without HAL registering a callback, these methods would + * need to be defined in the HAL base class. + * + * This would slightly break backwards compatibility so it should be discouraged; however, the + * base class could define a sane default implementation and not require that the child class + * implement this new method. This "sane default implementation" might only be possible in the + * case of listening to async events; if IPACM needs to query something, then this would not + * be backwards compatible and should be done via registering a callback so that IPACM knows + * this version of HAL supports that functionality. + * + * The above statements assume that only one version of the HAL will be instantiated at a time. + * Yet, it seems possible that a HAL_V1 and HAL_V2 service could both be registered, extending + * support to both old and new client implementations. It would be difficult to multiplex + * information from both versions. Additionally, IPACM would be responsible for instantiating + * two HALs (makeIPAHAL(1, ...); makeIPAHAL(2, ...)) which makes signaling between HAL versions + * (see next paragraph) slightly more difficult but not impossible. + * + * If concurrent versions of HAL are required, there will likely need to only be one master. + * Whichever version of HAL receives a client first may be allowed to take over control while + * other versions would be required to return failures (ETRYAGAIN: another version in use) until + * that version of the client relinquishes control. This should work seemlessly because we + * currently have an assumption that only one client will be present in system image. + * Logically, that client will have only a single version (or if it supports multiple, it will + * always attempt the newest version of HAL before falling back) and therefore no version + * collisions could possibly occur. + * + * Dislaimer: + * ========== + * Supporting multiple versions of an interface, in the same code base, at runtime, comes with a + * significant carrying cost and overhead in the form of developer headaches. This should not + * be done lightly and should be extensively scoped before committing to the effort. + * + * Perhaps the notion of minor version could be introduced to bridge the gaps created above. + * For example, 1.x and 1.y could be ran concurrently and supported from the same IPACM code. + * Yet, a major version update, would not be backwards compatible.
