# Regression test: clicking a pane's name in a second (#{P:}) status line to
|
|
# make it active must not retransmit images in other panes of the same
|
|
# window.
|
|
#
|
|
# The default MouseDown1Status binding is "switch-client -t=". When status
|
|
# is set to 2 or more, the second status line's default format lists each
|
|
# pane individually with a "pane" mouse range, so clicking a pane name there
|
|
# resolves that binding's target to a specific pane rather than a session or
|
|
# window - but switch-client still runs through server_client_set_session()
|
|
# (server-client.c), which used to call server_redraw_client() (forcing a
|
|
# full CLIENT_REDRAWWINDOW pass, wiping and retransmitting every image in
|
|
# the window) unconditionally, even though neither the client's session nor
|
|
# its current window actually changed - only the active pane within the
|
|
# already-current window did, which window_set_active_pane() and
|
|
# window_redraw_active_switch() already handle narrowly on their own.
|
|
#
|
|
# This is checked by counting DCS (\033P) sequences in the client's raw
|
|
# output while an inactive pane's own image (never touched by the click) is
|
|
# present: with the fix, none should appear.
