Subject: [PATCH sugar v2] sl#2955: Ignore Buddy updates before receiving the initial Buddy list
Organization: Sugar Labs Foundation
Signed-off-by: Ajay Garg <ajay@activitycentral.com>
---
Note that this patch is to be applied in full, and not over version-1 patch.
jarabe.model.neighborhood._Account tracks buddies by setting up handlers
for Telepathy signals and requests initial state from Telepathy to
populate the Neighbourhood with Buddies and shared Activities. In order
to prevent a race condition between requesting initial (i.e. current)
state and updates to Buddies and shared Activities, the signal handlers
are connected before requesting (and receiving) the initial state.
However, this means that updates may arrive before the initial state,
i.e. before the corresponding Buddy is known to Sugar. That's perfectly
OK and we can simply ignore the update as the Buddy list we will receive
later on will already include the updated properties.
