/**
* @brief
* Determine whether an "online" HTTP-based Internet reachability
This introduces a new 'OnlineCheckMode' configuration setting. This setting is intended to eventually deprecate 'EnableOnlineCheck' (long-term) and 'EnableOnlineToReadyTransition' (short-term). When asserted along with 'EnableOnlineCheck', 'EnableOnlineToReadyTransition' effects what can be thought of as a "continuous" online check mode, which is different from the "one-shot" online check more when 'EnableOnlineToReadyTransition' is not asserted but 'EnableOnlineCheck' is. Effectively, these two Booleans encode three online check modes: 1. None (!EnableOnlineCheck) 2. One-shot (EnableOnlineCheck && !EnableOnlineToReadyTransition) 3. Continuous (EnableOnlineCheck && EnableOnlineToReadyTransition) With this change, these three modes are all formalized. In "none" mode, as has been the case historically, there are no "online" HTTP-based Internet reachability checks. Any connected service and the manager state will terminate at the "ready" state and will not progress to "online". In "one-shot" mode, as has been the case historically, there is a single, one-shot "online" HTTP-based Internet reachability check for the default service. When the check succeeds, the associated service and the manager state will terminate at the "online" state. When the check fails, subsequent checks will be rescheduled according to "OnlineCheckIntervalStyle", "OnlineCheckInitialInterval", and "OnlineCheckMaxInterval" and will continue indefinitely until one succeeds or until the service is disconnected. In "continuous" mode, which is finalized with this change, there are ongoing "online" HTTP-based Internet reachability check for the default service. As with "one-shot" mode, when the first check succeeds, the associated service and the manager state will terminate at the "online" state. Thereafter, subsequent checks will be scheduled according to "OnlineCheckIntervalStyle" and "OnlineCheckMaxInterval". When the check fails, subsequent checks will be rescheduled according to "OnlineCheckIntervalStyle", "OnlineCheckInitialInterval", and "OnlineCheckMaxInterval". This is largely unchanged. However, what is new with this change is that when and if "OnlineCheckFailuresThreshold" is met, the service and manager state will be demoted to "ready" and the service will have its "Error" property set to "online-check-failed" while subsequent checks will continue. In the interim, if available, another service may be promoted to the default service and online checks will be initiated for it. When and if, for the demoted service, "OnlineCheckSuccessesThreshold" is met, the service "Error" property will be cleared and the service state promoted to "online", potentially causing it to become the default service again. --- src/connman.h | 9 ++++++++ src/main.c | 57 +++++++++++++++++++++++++++++++++++++++++++++++++++ src/service.c | 16 +++++++++++++++ 3 files changed, 82 insertions(+)
