Task priority in Plannings & Gants

Planning and Gantt will order the tasks considering the following criteria :

1) ‘Constrains’ / ‘Constrained by’ relationship

If task_A constrains task_B, then task_A has higher priority

CodevTT introduces two new relationships in MantisBT: “constrains” and “constrained by”. These have been introduced to set strong dependencies between tasks. The existing relationships (Duplicate of, Related to, Parent of, Child of) are not strict enough and may have been used by mantis users for other purposes (we do not want to change mantis users habbits).

2) A deadline is specified

A task having a deadline is higher priority to a task having no deadline defined

3) Deadline date

task_A with deadline on 2020-05-01 is higher priority than task_B wich deadline is 2020-05-15

If both tasks have a deadline defined, then the task with the earliest date has higher priority.

4) Status is 'feedback'

Tasks in feedback are lower priority

‘feedback’ is a special status, it is used to postpone a task for various reasons (missing information, waiting for acceptance, …), so a task in feedback cannot be completed and is therefore lower priority to any other status.

5) priority attribute

An ‘urgent’ task is higher priority than a ‘normal’ task

The mantis ‘priority’ attribute (low, normal, high, urgent, immediate) is used.

6) severity attribute

‘major’ is higher priority than ‘minor’

The mantis ‘severity’ attribute (…, tweak, minor, major, crash, block) is used.

7 ) Constrains vs not constraining

If task_A constrains nobody, and task_B constrains task_C, then IssueB is higher priority than task_A

To avoid being blocked, tasks constraining others must be acomplished as soon as possible.

8) The Lower the bug_id, the higher is the priority

If none of the previous criterion is conclusive, then tasks will be ordered by the mantis task id.
