Round2 init state use #10662

Pull request overview

Moves getInputs for schedules and curves to init_state
Reverted the previous method of calling init_state from process_idf because some of the unit tests read the idf snippet and act on that without calling the corresponding getInput. I figured it was not a good idea to automatically call getInputs when a developer might want to do something different. This should make it easier to move things to init_state because it won't affect existing unit tests.
Reverted a lot of the unit test changes from the previous init-state effort.
This may also mean I have to go back and add back in all the if (state.dataFluidProperties->GetInputFlag) call getFluidProperitesData occurrences that I removed on the previous effort. I didn't do that here but it may be necessary for unit testing, not sure yet.
Add a new warning counter for warning or severe errors encountered during input processing. Also include this count in ResultsFramework.
Report Curve objects that are not accessed for simulation purposes. If any curve is used in the simulation all curves are marked as used. This was improved to actually report curves that are not used.

The only change needed to allow curve manager getInput to be called more than once. It will likely not be called more than once but if it does it will give the same answer.

Probably better to set a flag and make sure the body is not called twice.

Well, the outer getInput call does protect from the second call. If a unit test calls the root function multiple times it would need to give the same answer. I think I did this before removing init_state from the unit test fixture (last thing I did) so maybe I can fix this and not have to change any unit tests. I'll just move that flag down into GetCurveInputData.

if (state.dataCurveManager->GetCurvesInputFlag) { GetCurveInput(state); GetPressureSystemInput(state); state.dataCurveManager->GetCurvesInputFlag = false; } void GetCurveInput(EnergyPlusData &state) { // wrapper for GetInput to allow unit testing when fatal inputs are detected - follow pattern from GetSetPointManagerInputs() bool GetInputErrorsFound = false; GetCurveInputData(state, GetInputErrorsFound); state.dataCurveManager->GetCurvesInputFlag = false; if (GetInputErrorsFound) { ShowFatalError(state, "GetCurveInput: Errors found in getting Curve Objects. Preceding condition(s) cause termination."); } } void GetCurveInputData(EnergyPlusData &state, bool &ErrorsFound)

There is a general practice in EnergyPlus of "protecting functions from bad inputs or bad calling contexts". This is actually counter-productive because it hides bad uses of the function. It's better programming to assert good inputs and good context (to the extent possible) within a function and then use those to progressively clean up the calling contexts.

hmm, why did I have to leave this here when FluidProperties is called in the fixture? Maybe this unit test needed something else now in init_state?

Oh, that's right. If the unit test does not have an idf snippet then process_idf will not be called and default fluids will not be set up yet. So this is correct.

Now that Timestep is processed in process_idf the time stamp is the first time step of the simulation. Before, NumTimeStepInHour = 0, now it is non-zero and Timestep defaults to 4.

This diff in IndoorLivingWall is disturbing. There is in fact 1 curve in this input file that is unused. But "unused" here means it was never read in because there are no other objects in this example file that have a curve object name input and therefore the curves are never read in. In this branch, moving GetCurveInput to init_state means the curves are read in and there is no unused object message in the error file. More disturbing is that if any curve name was an object input then all curves would be read in, marked as used, and even if a dangling curve object was in the input file it would not show as an unused input object. This branch shows that a different method for determining an unused object is necessary. Debugging this I noticed that if an object is "read" using getObjectItem it is marked as used, when in fact my interpretation of "used" is if it is actually accessed by another object. If all object's getInput are moved to init_state then all objects will be marked as "used". Moving markObjectAsUsed from getObjectItem to getObjectIndex (e.g., GetFanIndex) might be one way to go (probably some effort needed to make sure all parent objects call for an index of child objects).

-   ************* There are 1 unused objects in input.
-   ************* Use Output:Diagnostics,DisplayUnusedObjects; to see them.

ScheduleManager uses the "actually accessed" method in GetScheduleIndex and accurately reports unused schedules:

int GetScheduleIndex(EnergyPlusData &state, std::string const &ScheduleName)

    if (state.dataScheduleMgr->NumSchedules > 0) {
        GetScheduleIndex = Util::FindItemInList(ScheduleName, state.dataScheduleMgr->Schedule({1, state.dataScheduleMgr->NumSchedules}));
        if (GetScheduleIndex > 0) {
            if (!state.dataScheduleMgr->Schedule(GetScheduleIndex).Used) {
                state.dataScheduleMgr->Schedule(GetScheduleIndex).Used = true; <------- marks it as actually used

and has it's own ReportOrphanedSchedule function:

void ReportOrphanSchedules(EnergyPlusData &state)
{

for (Item = 1; Item <= state.dataScheduleMgr->NumSchedules; ++Item) {
    if (state.dataScheduleMgr->Schedule(Item).Used) continue;
    if (NeedOrphanMessage && state.dataGlobal->DisplayUnusedSchedules) {
        ShowWarningError(state, "The following schedule names are \"Unused Schedules\".  These schedules are in the idf");
        ShowContinueError(state, " file but are never obtained by the simulation and therefore are NOT used.");

getObjectItem removes an object from the unusedInputs list just because it was read in. This change puts that curve back in the list and waits for a call to getCurveIndex before removing the curve from the unusedInputs list. This change was prompted by IndoorLivingWall not showing the unused curve warning in this branch. Now curves shown as unused are actually not used in the simulation (i.e., if I have 10 curves in the input and only use 1 then 9 curves are unused).

We should probably change GetObjectItem to not do this at some point.
