Package: gnome-keyring
Version: 3.18.2-1
Severity: normal
Hi,
When I start gnome-session (not sure if startx is important to
reproduce) by
$ startx
Current gnome-keyring has the race with org.gnome.SessionManager
initialization of gnome-session. Because dbus doesn't seem to make the
name available to others immediately.
The sequence of the race is:
gnome-session gnome-keyring
.SessionManager init
run autostart apps
start by autostart
call .SessionManager.Setenv
call .SessionManager.ClientPrivate
.SessionManager available
This race becomes the cause of random Setenv failure for SSH_AUTH_SOCK
for example like following.
** Message: couldn't register in session:
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name
org.gnome.SessionManager was not provided by any .service files
To fix this, the attached patch starts to watch .NameOwnerChanged before
calling .SessionManager. With this, if .SessionManager is not available
yet, callings are done via .NameOwnerChanged notification.
Then, after makes sure calling of .SessionManager was done, this
removes watch of .NameOwnerChanged.
