Latest revision as of 21:57, 13 June 2007
The following code when added to Eventum 1.7.1 will provide a new 'report' in the reporting interface that outputs open issues according to a simple keyword search. The output is formatted in the syntax of TaskJuggler so that you can then play with planning, prioritizing, scheduling these issues using TaskJuggler.
WARNING: Beta quality.
The code is a working prototype, but there are surely improvements to be made. There is no sanitization of user input. The idea with this release is to get more eyeballs early to enlist more ideas and release improvements often. Of course, one next step is to see what if anything needs to change to make this work in version 2.0 of Eventum.
This code still needs to be authorized for release to MySQL according to their contribution guidelines.

/**
* Returns the date when 'work' began. Defined as the event when the issue was first "assigned" to someone.
*
* In Eventum, this is actually referred to normally as 'user_associated', however
* there are also other history types like auto assignments, remote assignments, and round-robin assignments that
* are event types we care about.
*
* Since we can assign multiple persons simultaneously (resulting in multiple records), we only need the first event to get the date.
*
* In all the history types, there are many that we could confuse with a user being assigned to an issue if we only
* relied on a string match for %associated% or %assigned%
* email_associated, email_disassociated, issue_all_unassociated, issue_associated, issue_auto_assigned, issue_unassociated,
* remote_assigned, rr_issue_assigned, scm_checkin_associated, user_all_unassociated, user_associated, user_unassociated
* In other words, this will NOT work ((htt_name LIKE '%associated%') OR (htt_name LIKE '%assigned%'))
* @see class.issue.php for details about assignment events.
* Issue bulk update can create an assignment event, but the history log will only show 'bulk update' so this is not
* fine-grained enough for this to really work. Should fix this in eventum's logging or otherwise build a more reliable way to
* record when an issue 'starts'.
*
* @param integer $issue_id The ID of the issue
* @return date $start The start date used in the TaskJuggler report

<p>
The scheduler in TaskJuggler looks for dependencies or start dates plus the amount of effort to figure out when things are
going to happen. Since we do not always have estimates of how much work is involved, nor do the historical start dates of when an issue was created correspond to relevant scheduling dates, we're forced to use 'guesstimates' for effort.
</p>
<p>
TaskJuggler schedules things ASAP (or ALAP, but that's not recommended practice - <a href="http://www.taskjuggler.org/manual/property_scheduling.html">see the manual: scheduling</a>) based on dependencies, start dates, work effort and resource availability. Since there is no way to nest tasks in Eventum, we must make all tasks depend on a pre-defined milestone. So, that means starting off your project file with something like the following.
{literal}
<pre>
task start "kickoff" {
milestone
start 2006-06-07
}
</pre>
{/literal}
Then, once you have a visual and all the numbers sliced five different ways, you can adjust from there in determining priorities, dependencies and do "what-if" scenarios to determine a good project plan.
