If an event handler/filter created a recursive main loop (just called
ecore_main_loop_begin()), then this recursive main loop should
continue to process events/handlers/filters from there and on, thus
event_current/event_filter_current/event_handler_current were
added. When going back from recursion, the current iterator should be
updated properly.
The following test case used to crash but not anymore:
#include <Ecore.h>
#include <Eina.h>
static int _log_dom;
#define INF(...) EINA_LOG_DOM_INFO(_log_dom, __VA_ARGS__)
static Ecore_Event_Handler *handle;
static int cb2(void *data, int type, void *event)
{
INF("cb2 - delete cb1 handle");
ecore_event_handler_del(handle);
ecore_main_loop_quit(); /* quits inner main loop */
return 0;
}
static int cb1(void *data, int type, void *event)
{
Ecore_Event *e;
INF("cb1: begin");
INF(" add cb2");
type = ecore_event_type_new();
ecore_event_handler_add(type, cb2, NULL);
e = ecore_event_add(type, NULL, NULL, NULL);
INF(" add event to trigger cb2: event=%p", e);
INF(" inner main loop begin (recurse)");
ecore_main_loop_begin(); /* will it crash due
* ecore_event_handler_del(handle) inside
* cb2()? It used to!
*/
INF("cb1: end");
ecore_main_loop_quit(); /* quits outer main loop */
return 0;
}
int main(void)
{
Ecore_Event *e;
int type;
ecore_init();
_log_dom = eina_log_domain_register("test", EINA_COLOR_CYAN);
/*
* Creating a new main loop from inside an event callback, and inside
* this new (inner) main loop deleting the caller callback used to
* crash since the handle would be effectively free()d, but when the
* recursion is over the pointer would be used.
*/
type = ecore_event_type_new();
INF("main: begin");
handle = ecore_event_handler_add(type, cb1, NULL);
e = ecore_event_add(type, NULL, NULL, NULL);
INF(" add event to trigger cb1: event=%p", e);
