Ensure the topolgy of the IAS is a-cyclic #70

Closed acaproni closed 6 years ago

acaproni commented 6 years ago

One of the constraint of the IAS is that the graph of all the nodes must be a-cyclic. The DASU, at startup, ensures that the topolofy of its ASCEs is a-cyclic but there is nothing checking that the whole topology of the IAS is a-cyclic.

The test could be done at startup by the Supervisor with a fail fast policy. But it should be possible to check the configuration independently for example by the GUIs to configure the CDB or by the alarm system administrator.

The cdbChecker has been added to the Extras module. It checks and report many problems in the CDB, including the check of cycles.

To run execute: iasCdbChecker -j PATH -x WARN PATH is teh path of the folder that contains the CDB. -x allows to set the log level of the messages produced by the tool. It can be very verbose at INFO and DEBUG level. But a level of WARN prints few important lines only.
