Category: Appender Group: v1.1.x >Status: Closed >Resolution: Fixed Priority: 5 Private: No Submitted By: Christian Rüegg (rueegg) Assigned to: Václav Zeman (wilx) Summary: Unnamed semaphores are not supported on Mac OS X Initial Comment: use named semaphores. See: http://stackoverflow.com/questions/1413785/sem-init-on-os-x ---------------------------------------------------------------------- >Comment By: Václav Zeman (wilx) Date: 2012-09-19 01:34 Message: Thank you for the bug report and testing. ---------------------------------------------------------------------- Comment By: Christian Rüegg (rueegg) Date: 2012-09-19 01:08 Message: Compiles fine and seems to run. ;-) Thanks ---------------------------------------------------------------------- Comment By: Václav Zeman (wilx) Date: 2012-09-18 12:54 Message: Thank you. I have attached a diff that fixes both of the problems that you have reported today. I have reimplemented Semaphore using named POSIX semaphores for MacOS X. Please try it and tell me if it works well for you. ---------------------------------------------------------------------- Comment By: Christian Rüegg (rueegg) Date: 2012-09-18 06:29 Message: Named semaphores seem to work in my quick test. Except I had problems on app exit (crash in log thread).
