Internal libraries

The internal libraries had been refactored. 

Now, almost all of them, have been moved under NMISNG: 

  • use NMIS; → Replaced by use NMISNG;
  • use func; → Replaced by use NMISNG::Util; 

Please, check the internal structure for other libraries. 

Database Access

As the new data backend has been moved from NMIS files to the mongo database, the node information access is different. 

Sys::ndinfo  has been replaced by  Sys::nmisng_node  and  Node::nmisng_node  can be accessed directly rather than accessing  Sys::nmisng_node

  • Sys::ndinfo->{system}  becomes hash returned by  Node::configuration()
    • Node::Configuration()->{roleType}  replaces  NMIS::loadLocalNodeTable()>{<a_node_name>} {role} 
    • Be warned that  Sys::ndinfo->{system}  key values often carry the strings "true" and "false" for boolean whereas  Node::configuration() returns hash key values will carry 0 and 1 for boolean.
      • Therefore one should always use Common::getBool() to evaluate key values.
    • Furthermore,  Node::configuration()  returns a clone copy each call, therefore it is advisable to set a variable if re-used:
  • Sys::ndinfo->{status}  becomes  Node::get_status_model_data()
    • NMIS8  ref(Sys::ndinfo->{status})  versus NMIS9  ref(Node::get_status_model_data)
      • NMIS8  Sys::ndinfo->{status}   was a hash of hashes, whereas
      • NMIS9  Node::get_status_model_data()   is an array of hashes.
    • NMIS8  Sys::ndinfo->{status}->{source}  is not a hashkey in  Node::get_status_model_data()
      • NMIS8  Sys::ndinfo->{status}  has entries either by 'source'  or by 'index', whereas
      • NMIS9  Node::get_status_model_data()  only has entries by 'index'
    • NMIS8 <object>->{<a_node>}->{active}  should be replaced by
      • Node::configuration→{active}
  • Sys::ndinfo->{sysUpTime}  is replaced by  Node::node_summary->{sysUpTimeSec}
