Branch activity is siloed: no overview of whats happening in a project

[Martin Pool]

Since launchpad knows about all commits across all (registered) branches, it would be good to show this as an indication of overall activity. This could come up on eg code.launchpad.net/bzr (along with some branches) or in a portlet (with a "more" link)

UPDATE: Related to bug 79041.

A simple formule could be "number of new unique revisions found by the branch scanner (date_created, not date) in the ancestry of all branches of the product/project)".

The "unique revision" bit is important, so branches that just pull from another branch do not contribute to the sum.

The "in the ancestry" bit is important, so a merge of several revisions from a branch Launchpad does not know about counts all the merged revisions.

The use of Revision.date_created instead of Revision.date is important to prevent revisions with bad dates from skewing this statistic. Since this statistic is measured over a period of time >> mirror interval, it would not be affected by the time-discrete nature of the branch scanning.

To clarify: I was talking about actually showing the text of a few
revisions, not just a count of them -- much as we show the most recent
bugs.

Okay. So something like:

 * Consider only mainline revisions of branches in this product/project (ignore revisions merged from a branch launchpad does not know about).
 * Filter out revisions where where date_created < date, and sort revisions by date (as in bug 79041).
 * Link to a branch that has this revision in its mainline.

This is now available through the revision feeds for the project. Is this sufficient for your use case?

[Björn Tillenius (bjornt)]

I would find this information useful, and I don't use feeds, so please show it in the web ui.

[Martin Pool (mbp)]

Also, the feed would be more discoverable if it was linked from a page showing similar information. At the moment that feed points back to the project code homepage which is a bit odd.

[Tim Penhey (thumper)]

Martin, can you come up with a pretty page for this?

It would use the same source as the revision feed, but formatted nicely for a project.
