[Notification] Notification Publishers not unregistered on componant "stop" when the se-notification service is unavailable

Details

  • Type: Bug Bug
  • Status: Resolved Resolved
  • Priority: Critical Critical
  • Resolution: Fixed
  • Affects Version/s: 5.0.3
  • Fix Version/s: 5.1.1
  • Component/s: Notifications
  • Security Level: Public
  • Description:
    Hide

    Usecase :

    • 1 petals instance with se-notification and se-kpi
    • 1 petals instance with components producing notifications
    • First, stop petals instance containing se-notif
    • Then, stop petals instance containing notification producers (components with notification property = "true")

    Producer never be unregistered. You could see that the "work/SavePublisherRegistrationRPs" directory of se-notif component contains publisher registrations.
    When you restart petals instances, an incoherant situation is obtained where notifications are duplicated because the same producer is registered twice.

Publisher that can't unregister on broker during component shutdown, mustn't re-register on broker at future startup (because registration is backuped by the broker) and must restore their previous state to be able to process notifications.

this issue is nearly fixed. the regiter publisher persisted file is always here after se-notif shutdown but linked side effects are fixed : subscritions and notifications aren't duplicated and so, flowstep parameters will also be ok in petals view.
See linked issues (PETALSCDK-25 and PETALSSENOTIF-7) for more information on fixed bugs.

On restart, the SE-Notification is sending a 'subscribe' message to the SE-KPI, but the SE-KPI does not handle this type of message, there is a problem in the recover process...
