#12440: perl Purple::timeout_add multiplites calls to given subroutine (using
default plugin code from doxygen)

Reporter:  marcelser  |        Type:  defect     
  Status:  new        |   Component:  plugins    
 Version:  2.7.1      |    Keywords:  plugins bug
----------------------+-----------------------------------------------------
 It seems like the "timeout_add" Function in the "Purple" perl library has
 a bug. I used the "perl test plugin" from doxygen and added a timeout
 (also the code-snippet from doxygen), the plugin does nothing else then
 calling timeout_add each 5 seconds and printing a timeout message to the
 debug log. But what happens is the following:

 First time the timeout is reached the subroutine is called once (you see
 one "Timeout reached" line in the debug log. Then you re-enable the
 "timeout_add" function in the function itself.

 Seconds time the timeout is reached the subroutine is called twice (two
 log linges), re-enable again

 Third time the timeout is reached the subroutine is called four times
 (four log lines)

 and so on...

 The calls to the timeout function always duplicate themselves and at a
 certain point pidgin hangs (especially if you decrease the timeout value
 even more). I didn't find a solution to this problem, if you don't re-
 enable the timeout nothing happens after timeout is reached (like the
 documentation states its only called once), but if you re-enable it the
 number of calls are duplicated on every timeout.

 I've attached the "perl test plugin" from doxygen with the timeout code
 snippet also from doxygen. Just enable the plugin and watch the debug log.
