FUNCTIONS
is_msg_valid
Check whether received message is valid in current state.
@param hash ref - message
@return valid - 1 @return invalid - 0
compare_given_state
Compare the current state to a given state name. Return -1 if the given state is earlier then the current, 1 if the current state is earlier then the given one and 0 if both are equal.
@param string - state name
@return current state is earlier - 1 @return given state is earlier - -1 @return states are equal - 0
get_current_timeout_span
Returns the time in seconds until the next timeout hits. When multiple timeouts are currently running (during test with multiple PRCs) the lowest of these timeouts is choosen. This value can be used for sleeping in reads.
@return int - timeout span in seconds
state_init
Initialize the state or reload it from database.
@param hash ref - initial state data (ignored in revive mode) @param bool - are we in revive mode?
@return success - 0 @return error - error string
update_installer_timeout
Update the timeout during installation.
@return success - (0, timeout span for next state change) @return error - (1, undef)
update_prc_timeout
Check and update timeouts for one PRC.
@param int - PRC number
@return success - new timeout @return error - undef
update_test_timeout
Update timeouts during test phase.
@return success - (1, new timeout) @return error - (0, undef)
update_keep_alive_timeout
Check whether keep-alive timeout has ended and if so, act accordingly.
@return success - (0, timeout span for next state change) @return error - (1, undef)
update_timeouts
Update the timeouts in $self->state_details structure.
@return success - (0, timeout span for next state change) @return error - (1, undef)
msg_takeoff
The reboot call was successfully executed, now update the state for waiting for the first message.
@param hash ref - message
@return success - (0, timeout span for next state change)
msg_start_install
Handle message start-install
@param hash ref - message
@return success - (0, timeout span for next state change) @return error - (1, undef)
msg_end_install
Handle message end-install
@param hash ref - message
@return success - (0, timeout span for next state change) @return error - (1, undef)
msg_error_install
Handle message error-install
@param hash ref - message
@return success - (0, timeout span for next state change) @return error - (1, undef)
msg_warn_install
Handle message error-install
@param hash ref - message
@return success - (0, timeout span for next state change) @return error - (1, undef)
msg_error_guest
Handle message error-guest
@param hash ref - message
@return success - (0, timeout span for next state change) @return error - (1, undef)
msg_start_guest
Handle message start-guest
@param hash ref - message
@return success - (0, timeout span for next state change) @return error - (1, undef)
msg_start_testing
Handle message start-testing
@param hash ref - message
@return success - (0, timeout span for next state change) @return error - (1, undef)
msg_end_testing
Handle message end-testing
@param hash ref - message
@return success - (0, timeout span for next state change) @return error - (1, undef)
msg_end_testprogram
Handle message end-testprogram
@param hash ref - message
@return success - (0, timeout span for next state change) @return error - (1, undef)
msg_error_testprogram
Handle message error-testprogram
@param hash ref - message
@return success - (0, timeout span for next state change) @return error - (1, undef)
msg_reboot
Handle message reboot
@param hash ref - message
@return success - (0, timeout span for next state change) @return error - (1, undef)
msg_quit
Handle message quit
@param hash ref - message
@return (1, undef)
msg_keep_alive
Handle message keep-alive. This function does not return anything because the caller ignores the return value anyway.
@param hash ref - message
next_state
Update state machine based on message.
@param Result class - message
@return success - 1 @return error - undef
Update the state based on a message received from caller. The function returns a timeout span value that is the lowest of all currently active timeouts. The given message can be empty. In this case only timeouts are checked and updated if needed.
