[E-devel] strange bug with Ecore and timers

[Mathieu SCHROETER]

Hello,

I've a strange bug with Ecore when I will add a timer after the
ecore_main_loop_begin (); when this main_loop is in a pthread.

I use the last Ecore snapshot 0.9.9.041 and the bug can be reproduced
with the file source attached to this email.

For compile, just : gcc buggy_timer.c -lecore -lpthread -o buggy_timer

Without change in the source, the output is :

 wait 5 sec
 create timer 2


In this case, a timer2 is created ~5 seconds after the
ecore_main_loop_begin (); and never start. The ecore_main_loop_begin ();
is called from a pthread and it seems to be the problem.
After the "create timer 2", each second the text "TIMER 2" must
appear but it doesn't work.

If you uncomment the lines 52 and 53. Then timer1 is created
before ecore_main_loop_begin (); and in this case, after 5 seconds
in this example, the timer2 is created too.. and the output is :

 create timer 1
 wait 5 sec
 TIMER 1
 TIMER 1
 TIMER 1
 TIMER 1
 create timer 2
 TIMER 1
 TIMER 2
 TIMER 1
 TIMER 2
 TIMER 1
 TIMER 2
 TIMER 1
 TIMER 2
 TIMER 1
etc,..


This output is okay.. Just a thing is strange in this case too, CTRL+C
break the loop but the program is not killed.

I don't understand the bugs.


And if I put de main_loop_begin in the pthread, it is just because I
use Ecore in a library.

  while (1)
    sleep (100000);

  ecore_shutdown ();
  return 0;
}
