Soft Due Date plugin

This is the Soft Due Date plugin for Trac. It implements automatic setting of a soft due-date field for every ticket based on its Priority.

Known issues

• The soft due date is only set when a ticket is created/modified, so making this plugin useful after installing it on an active Trac installation requires a trivial change to all tickets.
• The soft due date ticket field can be set when creating/modifying a ticket, but the value to which it will be set is ignored.
• The soft due date can only be based on the priority at the moment.
• The priority-to-time-offset is currently hard-coded in the source, while it should be changeable using the administrator interface.

Installation

Before you can use this module, you need to install the DateFieldPlugin module. Then, add a soft_due_date field to the configuration file:

[ticket-custom]
soft_due_date = text
soft_due_date.date = true
soft_due_date.date_empty = true
soft_due_date.label = Soft Due Date
soft_due_date.value =

In order to add the new soft due-date field to a Trac ticket report, change your report query to something like this:

SELECT id AS ticket, summary, [...],
  c.value AS soft_due_date
FROM ticket t
LEFT JOIN ticket_custom c ON t.id = c.ticket AND c.name = 'soft_due_date'

To sort the table by soft due date:

ORDER BY date(c.value) ASC

Or, to sort the table keeping every unset soft_due_date at the bottom:

ORDER BY case when date(c.value) then date(c.value)
  else date("9999-12-31") end ASC, created, [...]

It can also be used next to a configurable due_date field, after you added it to the configuration file just like the soft_due_date field:

SELECT id AS ticket, summary, [...],
  c.value AS soft_due_date,
  d.value AS due_date
FROM ticket t
LEFT JOIN ticket_custom c ON t.id = c.ticket AND c.name = 'soft_due_date'
LEFT JOIN ticket_custom d ON t.id = d.ticket AND d.name = 'due_date'
ORDER BY min(
  case when date(c.value) then date(c.value) else date("9999-12-31") end,
  case when date(d.value) then date(d.value) else date("9999-12-31") end
) ASC, created, [...]
