Browse files Browse the repository at this point in the history
… IM engine. (#28104)

* Integration of ReportSchedulers into the ReadHandler and IM engine.

Also added a static report scheduler to use in all test relying on the IM engine, also added test flags in ReportScheduler replace ReadHandler timing flags

Refactored the TestReadInteraction to adopt correct behavior

* Restyled by clang-format

* Restyled by gn

* Moved namespaces into class to avoid namespace pollution

* Fix missing pragma once and copyright

* Update src/app/reporting/ReportScheduler.h

Co-authored-by: mkardous-silabs <[email protected]>

* Apply suggestions from code review

Co-authored-by: Boris Zbarsky <[email protected]>

* Removed OnIntervalsChanged, removed TestReadInteraction from ReportScheduler's friend class and refactored the tests to use wrapper functions, refactored tests for the removal of OnIntervalsChanged, removed reportscheduler nullptr check form controllers

* Restyled by clang-format

* Fix for the TimerDelegates

And also added a default Scheduler to controllers

* Restyled by clang-format

* Added a timer Context class to allow interface between timer delegates, ReadHandlerNodes and SynchronisedReport Scheduler

* Fix using InteractionModel... error

* Added Platform::Delete() for allocated TimerDelegate and ReportScheduler on controller

* Update src/app/ReadHandler.cpp

Co-authored-by: mkardous-silabs <[email protected]>

* Update src/app/TimerDelegates.h

Co-authored-by: Boris Zbarsky <[email protected]>

* Addressed PR comments, next step trying to reduce RAM bloat

* Restyled by clang-format

* Removed IntrusiveList from the report Scheduler

* Removed ReadHandlerNode's inheritance of IntrusiveListBase

* Restyled by clang-format

* Fix commented code and comment syntax

* Restyled by clang-format

* Update src/app/tests/TestReportScheduler.cpp

Co-authored-by: Boris Zbarsky <[email protected]>

* Added extra check on timerDelegate in DeviceController, removed logging causing failure in linux CI

* Restyled by clang-format
