* Added -forkautostatsport cmdline option that automatically sets a unique port for each forked child. Ports used will start at statsPort+1. * Improved statsport /exec listener so it returns a different error message when the exec callback isn't registered, the cmd itself was not processed by the exec or the cmd is missing the 'c=' param. Forking * Exposed ChildProcessIndex in ForkHelper [REVIEW] Brandon.Schaeffer, Brian.Bekich #ROBOMERGE-AUTHOR: louisphilippe.seguin #ROBOMERGE-SOURCE: CL 18770568 via CL 18770579 via CL 18770587 via CL 18774066 via CL 18774960 #ROBOMERGE-BOT: UE5 (Release-Engine-Test -> Main) (v903-18687472) [CL 18775041 by louisphilippe seguin in ue5-main branch]
