Subject: [PATCH] session: remove "session-error" signal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This partially reverts commit de5cd71.
Problem with that commit is, that it practically renders
the "session-auth-*" signals from vnc session useless.
That's because gtk-vnc currently emits "vnc-error" before each
"vnc-auth-*" signal and the error callback in virt-viewer-app.c
calls virt_viewer_app_disconnected(), which in turn closes
the session.
As a consequence, virt-viewer never retries authentication
with vnc, it simply exits.
Since the last commit, vnc, similarly to spice, emits
"session-disconnected" with the appropriate error message. Thus
there's no need to maintain separate "session-error" signal
for now.
With vnc, this error message is shown to the user in a dialog,
if the disconnect happened during the init phase.
"session-auth-*" callbacks create their own dialogs, so
initialized must be set to TRUE to avoid having a dialog
displayed twice.
