c833c0866f
From the Present extension specification: An event context is associated with a specific window; using an existing event context with a different window generates a Match error. If eventContext specifies an existing event context, then if eventMask is empty, PresentSelectInput deletes the specified context, otherwise the specified event context is changed to select a different set of events. If eventContext is an unused XID, then if eventMask is empty no operation is performed. Otherwise, a new event context is created selecting the specified events. Without this change, there's no way for a client to explicitly change or destroy an existing event mask entry. Trying to do so as specified above would just result in a protocol error. v2: (Keith Packard) * Use dixLookupResourceByType instead of walking window_priv->events * Return BadMatch if the existing event context is associated with a different window or client * Call LEGAL_NEW_RESOURCE again when creating a new event context * Drop invalid "leak fix" Signed-off-by: Michel Dänzer <michel.daenzer@amd.com> Signed-off-by: Keith Packard <keithp@keithp.com> Reviewed-by: Keith Packard <keithp@keithp.com> Reviewed-by: Kenneth Graunke <kenneth@whitecape.org> |
