Category: puredata Group: None Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: print character 123 freezes gui
Initial Comment: On WinXP and Miller's pd039_test7 typing '{' (ascii 123) after print in an object box hangs the gui, apparently because the tcl is waiting for a closing '}' before proceeding.
In the source code, dopost() in s_print.c, it looks like four characters are escaped: '', '{', '}', and ';'. But if they are escaped they should not freeze the gui...
static void dopost(const char *s) { ... if (c == '' || c == '{' || c == '}' || c == ';') <- if it's a dangerous character for tcl upbuf[ptout++] = ''; <- add a backslash before the dangerous character upbuf[ptout] = s[ptin]; <- then put the character ... sys_vgui("pdtk_post {%s}\n", upbuf); <- then send it to tcl interpreter
If I try entering them in a print box I get different results. '' and '}' are rejected: }: dropped : dropped ';' is accepted '{' freezes the gui.
In g_editor.c:
void canvas_key(t_canvas *x, t_symbol *s, int ac, t_atom *av) {
... if (keynum == '' || keynum == '{' || keynum == '}') <-a dangerous character { post("%c: dropped", (int)keynum); <-should be dropped, but for '{' this doesn't get printed return; } ...dopost() is called from post() so '{' is causing trouble even when it is escaped with a backslash.
