From db2d654347e06fe7e40a498eee02e523936f4a53 Mon Sep 17 00:00:00 2001 From: Kaz Kylheku Date: Fri, 17 Mar 2017 06:47:48 -0700 Subject: trace: implement redefinition checks. The tracing module should warn when traced functions or methods are being redefined, and stop tracing the original methods. * eval.c (trace_check): New function. Calls sys:trace-redefined-check if the trace module has been loaded, otherwise does nothing. (op_defun, op_defmacro): Call trace_check to have a warning issued for a redefined traced function or macro. * eval.h (trace_check): Declared. * lisplib.c (trace_loaded): New global variable. (trace_instantiate): Flip trace_loaded to t. * lisplib.h (trace_loaded): Declared. * share/txr/stdlib/trace.tl (sys:trace-redefine-check): New function. Checks two situations: traced function or method is redefined (neither old nor new is traced any longer), and traced method is overridden (base method continues to be traced, override is not traced). * struct.c (static_slot_ensure): Do a trace check here, taking care of defmeth. --- lisplib.h | 1 + 1 file changed, 1 insertion(+) (limited to 'lisplib.h') diff --git a/lisplib.h b/lisplib.h index 57a98d6e..e54ec5c6 100644 --- a/lisplib.h +++ b/lisplib.h @@ -26,6 +26,7 @@ */ extern val dl_table; +extern val trace_loaded; void lisplib_init(void); val lisplib_try_load(val sym); void set_dlt_entries(val dlt, val *name, val fun); -- cgit v1.2.3
