La fonction get_ping_from_temp_log avait une complexité cyclomatique de 15.
|
||||
|
||||
Modifications:
|
||||
Ligne 51 et 53 (anciennement 54 et 56):
|
||||
Retirer la verification if, car peut importe ce qu'il se passe, p_reg ne peut pas être null, la fonction ce serait arretée
|
||||
Ligne 73,74 et 75 (anciennement 116, 117 et 118):
|
||||
Retirer encore du code mort, car la verification est inutile, avant de déplacer le while, read_line était forcemment null à ce moment.
|
||||
Le while a été segmenté en une fonction find_ping() à part, qui prend en paramètre ce dont il a besoin et retourne ping.
|
||||
|
||||
Tous ces changements on fait passer la complexité cyclomatique de get_ping_from_temp_log de 15, à 5. find_ping() quand a lui est également à 8.
