[spice-gtk v2 1/7] gtk-session: prefer early check to agent connectivity

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Victor Toso <me@xxxxxxxxxxxxxx>

In case the agent is disconnected, we we don't need to create the
struct RunInfo, GMainLoop and add handlers to some signals.

Before this patch, spice_main_channel_clipboard_selection_request()
was always called even if agent was not connected, which would log
a critical message in agent_clipboard_request() and unnecessary call
to spice_channel_wakeup().

This patch also removes one goto and related cleanup label.

Changes in v2:
- Improved commit log based on a function call that is now avoided:
  spice_main_channel_clipboard_selection_request (Frediano)
