Power Management
For devices which have remote power management (e.g. from one of the PDUs) we implement a standard power state monitoring and management component for the FSM. This needs to be enabled in the derived app constructor. To stay enabled, m_powerDevice and m_powerChannel must be not empty strings after the configuration. These could be set in the derived app defaults. If power management is enabled, then while power is off, appLogic will not be called. Instead a parrallel set of virtual functions is called, onPowerOff (to allow apps to perform cleanup) and whilePowerOff (to allow apps to keep variables updated, etc). Note that these could merely call appLogic if desired.

◆ execute()

template<bool _useINDI>

int MagAOX::app::MagAOXApp< _useINDI >::execute ( void )

virtualinherited

The execute method implementing the standard main loop. Should not normally be overridden.

Performs final startup steps. That is:

Verifies correct effective user-id by comparison to logs directory.
PID locking lockPID()
log thread startup by logThreadStart()
signal handling installation by setSigTermHandler()
appStartup() is called
INDI communications started by startINDI()
power state is checked, pausing if unknown (if being managed)

Errors in the above steps will cause a process exit.

Then commences the main event loop. Conditions on entry to the main loop:

PID locked
Log thread running
Signal handling installed
appStartup successful
INDI communications started successfully (if being used)
power state known (if being managed)

In the event loop, the power state is checked (if being managed). If power is off, then onPowerOff is called. If power is on, or power is not managed, appLogic is called. These methods are implemented in derived classes, and are called every m_loopPause interval.

If an error is returned by either onPowerOff or appLogic, or a signal is handled, then the shutdown is managed. This includes shutting down INDI, calling appShutdown, and unlocking the PID. The log thread will shutdown.

◆ stateLogged()

template<bool _useINDI>

int MagAOX::app::MagAOXApp< _useINDI >::stateLogged

inherited

Updates and returns the value of m_stateLogged. Will be 0 on first call after a state change, >0 afterwards.

This method exists to facilitate logging the reason for a state change once, but not logging it on subsequent event loops. Returns the current value upon entry, but updates before returning so that the next call returns the incremented value. Example usage:

if( connection_failed ) //some condition set this to true
{
   state( stateCodes::NOTCONNECTED );
   if(!stateLogged()) log<text_log>("Not connected");
}

In this example, the log entry is made the first time the state changes. If there are no changes to a different state in the mean time, then when the event loop gets here again and decides it is not connected, the log entry will not be made.

Returns: current value of m_stateLogged, that is the value before it is incremented.

inherited

Start a thread, using this class's privileges to set priority, etc.

The thread initialization synchronizer bool is set to true at the beginning of this function, then is set to false once all initialization is complete. The thread exec function should wait until this is false before doing anything except setting the pid. This is to avoid privilege escalation bugs.

The interface of the thread start function is:

static void impl::myThreadStart( impl * o )
{
   o->myThreadExec(); //A member function which actually executes the thread
}

where impl is the derived class, and mThreadStart and myThreadExec are members of impl.

Returns: 0 on success; -1 on error

Parameters

[out]	thrd	The thread object to start executing
	thrdInit	[in/out] The thread initilization synchronizer.
	tpid	[in/out] The thread pid to be filled in by thrdStart immediately upon call
	thProp	[in/out] The INDI property to publish the thread details
[in]	thrdPrio	The r/t priority to set for this thread
[in]	cpuset	the cpuset to place this thread on. Ignored if "".
[in]	thrdName	The name of the thread (just for logging)
[in]	thrdThis	The `this` pointer to pass to the thread starter function
