Test process:

Two test users:

User 1. Tempy (the user exists in the openifre database .)

User 2, tempn (the user does not exist in the Database)

Operation:

User Tempy adds user tempn as a friend on the spark client.

No matter how many times the user exits and logs on to Tempy, tempn is always in the friends list of Tempy.

The user (Tempy) must manually delete the friend (tempn ).

We recommend that you do not store user data that does not exist in the database.

Cause:

The ofroster list in the database keeps saving Tempy's friend data for adding tempn: sub = 0 (none ),

Repair suggestions:

When a friend is added, the server first checks whether the user in the database exists. If the user does not exist, an error message is returned.
