Subject: [PATCH] session: remove "session-error" signal
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8

|
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.
