Hi All,
When I move the next sample in RHEL6.5(glib2-2.22.5-7.el6) and
Ubuntu14.04(libglib2.0-0:amd64 2.40.0-2), movement is different.
* Sample : test2.c
{{{
#include <stdio.h>
#include <stdlib.h>
#include <glib.h>
#include <sys/times.h>
guint t1, t2, t3;
gboolean timer_func2(gpointer data){
printf("TIMER EXPIRE!2\n");
fflush(stdout);
return FALSE;
}
gboolean timer_func1(gpointer data){
clock_t ret;
struct tms buff;
ret = times(&buff);
printf("TIMER EXPIRE!1 %d\n", (int)ret);
fflush(stdout);
return FALSE;
}
gboolean timer_func3(gpointer data){
printf("TIMER EXPIRE 3!\n");
fflush(stdout);
printf("remove timer1!\n");
fflush(stdout);
g_source_remove(t1);
printf("remove timer2!\n");
fflush(stdout);
g_source_remove(t2);
printf("remove timer3!\n");
fflush(stdout);
g_source_remove(t3);
return FALSE;
}
int main(int argc, char** argv){
GMainLoop *m;
clock_t ret;
struct tms buff;
gint64 t;
m = g_main_new(FALSE);
t1 = g_timeout_add(1000, timer_func1, NULL);
t2 = g_timeout_add(60000, timer_func2, NULL);
t3 = g_timeout_add(5000, timer_func3, NULL);
ret = times(&buff);
printf("START! %d\n", (int)ret);
g_main_run(m);
}
}}}
* Result
---- RHEL6.5(glib2-2.22.5-7.el6) ----

root@a1be102:~# ./test2
START! 1718163089
TIMER EXPIRE!1 1718163189

remove timer1!
(process:1410): GLib-CRITICAL **: Source ID 1 was not found when attempting to
remove it
remove timer2!
remove timer3!
These problems seem to be due to a correction of next glib somehow or other.
* https://github.com/GNOME/glib/commit/393503ba5bdc7c09cd46b716aaf3d2c63a6c7f9c
In g_source_remove() until before change, the deletion of the timer which
practice completed is possible, but g_source_remove() after the change causes
an error.
Under this influence, we get the following crit error in the environment of
Pacemaker using a new version of glib.
lrmd[1632]: error: crm_abort: crm_glib_handler: Forked child 1840 to
record non-fatal assert at logging.c:73 : Source ID 51 was not found when
attempting to remove it
lrmd[1632]: crit: crm_glib_handler: GLib: Source ID 51 was not found
when attempting to remove it
It seems that some kind of coping is necessary in Pacemaker when I think about
next.
* Distribution using a new version of glib including Ubuntu.
* Version up of future glib of RHEL.
A similar problem is reported in the ML.
