Dear Brian and others, Thank you for your quick reply, Brian-san.Instead of forking two process, I've decided to fork only one process for sending an email,and using run_on_start and run_on_finish for the spinner. And the same problem still persists. Strange thing is that I added print "run_on_start" and print "run_on_finish" to each callback subroutines to make sure they are processed. They do, but spinners do not respond right.
In other code using Parallel::ForkManager, Spinner worked fine, it spin and stopped when I expected. but when forked to send an email, spinner gets grumpy all the sudden. I attached two test cases, one is a revised but problem still persists code, and other works sort of fine.
There is other problem I need your guide for. when I add hide() for spinner after stop(), spinner does not show at all. Have you had this problem??
Thank you again. Tsuyoshi On 2014年05月29日 12:04, Brian Manning wrote:
Your sample code uses Parallel::ForkManager, and uses the wait_all_children method to wait for the children to end processing. From the Parallel::ForkManager docs: -begin quote- wait_all_children You can call this method to wait for all the processes which have been forked. This is a blocking wait. -end quote- So you are calling a method that says it will block, hence your demo script is blocking. Instead of using "wait_all_children" (which blocks), I would look at using the "run_on_finish" callback method instead, and make the call to stop the spinner from that callback method.

Although a program forks, and one child process suppose to spin the spinner while other sends email, the spinner does not spin until the email is completely sent. How does you all usually handle this spinner thingy??? Am i on a right path?? I attached my test case. You need to add SMTP host name, your email address, and password. Thank you.
