Support custom milestone ordering.

[otavio@…]

Should be interesting if roadmap module support ordering using some code to handle alfa, beta, pre and so on.

For example:

1.0 alfa
1.0 pre
1.0

[cmlenz]

I don't think we can possibly support all different naming conventions for milestones. Note that some projects may not use terms like alpha or beta at all.

Currently, milestones are ordered primarily by date, and second alphabetically by name. It may make sense to support manual ordering of milestones so that the admin could simply say at what position a particular milestone should appear relative to the other ones. ​JIRA supports that, for example.

[cmlenz]

Not for 0.9.

I think you may want to include this in some milestone, particularly in light of how the Roadmap looks since the addition of the 0.10 - 0.12 milestones. They appear to be scheduled before 0.9.4 which I'm fairly certain is not the intent.

I'm suggesting 0.10 should be the target milestone for this, but I certainly have no idea if that is realistic

Natural sort ordering for milestone names?

(as in source:trunk/trac/versioncontrol/web_ui/browser.py@latest#L33​)

[cboos]

Use natural ordering for Milestones in the roadmap view

[cboos]

See attachment:natural_order_sort_for_milestones.diff​

That could be also ported to 0.9-stable, in order to
correctly show Trac's own milestones, for the next upgrade.

Nice patch :-)

Please check in, and I'd be +1 on porting to 0.9-stable.

[cmlenz]

Hold on, actually that breaks the ordering by due date.

The ordering should ideally be:

1. completed date (already completed first, completed earlier first)
2. due date (due date set first, due date earlier first)
3. name (natural order)

in that order.

[cmlenz]

See also #2209.

Note that the due date sorting is already performed in the SQL query.

[cboos]

Updated patch in order to take the completed and due date into account.

[cboos]

See updated patch (attachment:natural_order_sort_for_milestones.2.diff​).

I think this would also partially do what's requested in #2209
(what's left to be done would be the ordering in the query listing).

But in the meantime you can already check the Roadmap's ordering
for correctness.

[cmlenz]

This should be moved to the Milestone class so that the ordering is consistent.

sort milestones using DSU idiom

[cboos]

Finalized version of the patch committed as r2758 and r2759.

(would be nice to be able to set two milestones, btw)

[mgood]

Using "sorted" with the "key" parameter in Python 2.4, or the "decorate-sort-undecorate" (DSU) idiom in earlier versions is a cleaner and faster way to sort values than using comparators. I've added a patch to do the milestone natual-ordering using the built-in sorted, or a small compatibility method to simulate it using DSU. It still needs ported to the browser ordering, but that's a little more convoluted, so I'll have to revisit it after work.

[cboos]

Updated mgood's patch so that it applies on top of r2758

[mgood]

added the DSU idiom in [2760] and [2761]
