Just one point : you’ll have to reinitialize your password. Use “Lost password” feature.
One user entered dependencies in the project, effectively disabling the planning functionality.
He created a milestone. Then an activity with a successor link to that milestone. A sub-activity had the same milestone as a predecessor. This created a cycle via a parent.
When pressing the planning button - i get no response, probably there is a stack overflow message on the remote server. Using traceLog i was able to pinpoint the problem.
In model/PlanningElement in the function initializeFullList($list) there is a call to a recursive function self::getRecursivePredecessor($directPredecessors,...) which keeps running and probably running out of space.
What is the best idea and place to discover cycles in the planning structure?
(third trial to add my solution)
I added a check to the getRecursivePredecessor function in PlanningElement.php The added argument $visited keeps tabs on which $idPrec are already visited. Therefore it will prevent a stack overflow. It seems that the dependency check also used this function and wasn't able to discover a cycle due to the stack overflow.
Hi,
Great.
Tanks for the fix : it will ensure that planning will wotk on any cases.
On my side, I worked on fixing dependency loop control to avoid this use case.
Will be included in V5.3
