a=openpgp; fpr=3BB639E56F861FA2E86505690FDD682D974CA72A Port straight to GTK 4 rather than GTK 3, since GTK 4 is where new development happens and GTK 3 is old itself now. GTK 4 drops GtkContainer, GdkScreen, and the gtk_main()/ gtk_dialog_run() family perf's GTK UI relied on. Containers get per-widget setters (gtk_box_append() and friends), monitor geometry comes from GdkMonitor instead of GdkScreen, and the main and error-dialog loops become explicit GMainLoops quit from the "close-request" and "response" signals. Widgets are visible by default now, so gtk_widget_show_all()/set_no_show_all() go away, and the remaining gtk_widget_show()/gtk_widget_hide() calls become gtk_widget_set_visible() (with a small wrapper where "response" needs to pass gtk_widget_hide() as a callback, since it no longer exists as a plain function). gtk_ui_progress__finish() skips destroying a progress dialog that was never created, since gtk_window_destroy() asserts on NULL where the old widget destroy tolerated it. Two spots the GTK 2 to GTK 3 port had missed (builtin-annotate.c, ui/gtk/setup.c still using HAVE_GTK2_SUPPORT and gtk_main_quit()) are fixed to match. Runtime fallout from the new signal-driven loops: the error dialog's nested loop hung if the parent window closed (GTK_DIALOG_DESTROY_WITH_PARENT destroys without emitting "response"); gtk_info_bar_get_content_area() is gone, breaking GTK_INFO_BAR_SUPPORT; the progress dialog's static widget pointers dangled after a manual close; perf_gtk__error() and the warning functions reused an exhausted va_list when vasprintf() failed. The error loop is tracked in a list instead of a single pointer, since perf_gtk__error() can be called re-entrantly (the dialog isn't modal) and a lone global leaked the outer loop when that happened. The list is only ever touched from the main thread: perf_gtk__error() updates it while handling a dialog, and SIGINT/SIGQUIT/SIGTERM are deferred to a GLib source via g_unix_signal_add() rather than calling perf_gtk__exit() straight out of a real signal handler, so quitting on those signals is serialized with the list update instead of racing it from signal-handler context. SIGSEGV/SIGFPE keep a real handler, since they're synchronous faults with no "later" to defer to, but it's pared down to reporting and reraising the default disposition (perf_gtk__fatal_signal()): there's no safe way to run GTK/GLib code from the faulting context. stdarg.h, stdio.h, and string.h are now included explicitly where used (util.c, hists.c, annotate.c) rather than relying on transitive includes, which musl doesn't guarantee. The gtk4-infobar feature check is dropped: GtkInfoBar has existed unconditionally since GTK 3.10, so the check can only ever pass, and it was failing outright here anyway since gtk_info_bar_new() is deprecated and the check treats deprecation warnings as errors. HAVE_GTK_INFO_BAR_SUPPORT and its statusbar-only fallback go away; the info bar is now built unconditionally.
