Changes for version 1.844 - 2019-08-14

  • Resolved MCE stalling when specifying max_retries with init_relay. Ditto for loop_timeout with init_relay on UNIX platforms. Thank you, Chris Denley.
  • Enhanced loop_timeout to handle workers dieing uncontrollably from any user_tasks (i.e. task_id >= 0). Previously, only task_id == 0.
  • Improved IPC on the Windows platform for edge case when a worker is awaiting input while the manager process is restarting a worker.
  • MCE, MCE::Child workers exit immediately upon receiving a SIGSEGV signal. This safeguards IPC from stalling inside the manager process.
  • Enhanced the _wait_one private function in MCE::Child.
  • Removed Prima from the list for auto-enabling the posix_exit option. Prima (since 1.52) is parallel safe during global cleanup.
  • Reached 100% Pod coverage.
