Do not use SHM if display name doesn't look local.
|
|
|
|
Verifying availability of SHM only by using response of SHM Attach is not
|
|
reliable. There is always small chance that when we are a remote client of X
|
|
server, we'll get shmid that is already in use by some local X client. In that
|
|
case X server can not recognize that it is not accessing our shared memory but
|
|
the one of the other client and will report success.
|
|
|
|
This adds check for display name equivalent to one that was in Qt4. Determining
|
|
whether the connection is local/remote from display name is not 100% reliable,
|
|
but worked fine for years in Qt4.
