ACE VERSION: 6.3.0
(this bug still exists in version 6.4.0)
Our test codes looks like this:
after a while , we found dead-lock occurs at line 4.
I check the code and found that :
purge_pending_notifications can only purge message in notify queue
messages in pipe can not be purged
so calling notify() after purge_pending_notifications() can always leads one message be write to pipe
So when I keep calling like this , soon buffer of pipe will full and notify() will be blocked , then dead-lock occurs
we are using this two interfaces building important functions of our application
we will appreciate it if this bug being fixed soon
poor English, sorry!
