2005-10-03 Elijah Newren <newren@gmail.com> Truncate ridiculously long titles to avoid crashing or letting the pager crash. Based on patch from Ray, incorporating suggestions from Havoc and some extensions of my own. Fixes #315070. * src/display.c (set_utf8_string_hint, meta_display_open): * src/xprops.[ch] (meta_prop_set_utf8_string_hint): Move set_utf8_string_hint() to props.[ch], namespace it ("meta_prop_"), and make it public * src/tabpopup.c (utf8_strndup, meta_ui_tab_popup_new): * src/util.[ch] (meta_g_utf8_strndup): Move utf8_strndup() to util.[ch], namespace it ("meta_g_"), and make it public * src/display.c (meta_display_open): * src/display.h (struct _MetaDisplay): add net_wm_visible_name and net_wm_visible_icon_name atoms to the list of atoms we work with * src/window-props.c (set_window_title, set_icon_title): If title length is greater than 512, truncate it and set _NET_WM_VISIBLE_NAME or _NET_WM_VISIBLE_ICON_NAME accordingly
