Ignoring weekends!

[Robert Inder]

I have a handful of tickets which have start and end dates, and estimated hours.

The chart is ignoring/over-riding the start date to calculate its own. But in doing so, it ignores weekends.

So I have a ticket with start date 2012-01-09 and finish date 2012-02-17 and 150 hours estimated. But when I draw a chard with hoursPerDay=7, it shows up on the chart as end date 2012-02-17, start date 2010-01-27.

So the duration has been reduced to 22 days elapsed, which is 149 hours if you work seven days a week.

If I reduce "hoursPerDay" to 5, the start day is pushed to the 19th of January. 30 days at 5 hours per day, 7 days per week.

So contrary to what it says at ​http://trac-hacks.org/wiki/TracJsGanttPlugin this is taking no account weekends.

Robert.

Ooops! Forgot to change the Trac release. Sorry.

(In [11079]) Cleaner date adjustment using calendarOffset. Refs #9533, #9300, #9042, #9515.

Scheduler used to assume work week. Now let calendarOffset() do that.

Also, it seems rounding errors would creep in and some datetimes would have non-zero microseconds. This tests for beginning and end of day with a little delta.

I'm not 100% sure why this is necessary but the wrong things seemed to get updated if I didn't do this and give demonstrably wrong results.

(In [11142]) Correct end-of-day adjustments for ASAP and < 100% effort. Refs #9533, #9300.

When working forward to build an ASAP schedule, partial takes caused the tasks to shift forward more than their scheduled length.

If one resource can work 8 hours per day and another can only work 4, the second resource takes twice as long to complete the same task. But without this clean up, ALAP scheduling took an 8-hour task at 4 hours per day from the end of day 2 to the middle of day 1. With this change, if all available hours are used up, the rest of the day is consumed so that 8-hour task goes from the end of day 2 to the start of day 1.

The calendar-based scheduler handles weekends by default. Ambitious users can plug in their own calendar for other needs.
