Subject Re: A proposal to move away from Jira-centric development
Date Tue, 16 Aug 2016 17:31:12 GMT
Back to the topic at hand.  First, let us establish that all of this stuff will be happening
“on the mailing lists”, all JIRA updates are sent to commits@ with the reply-to set to
dev@, so “JIRA” is still “on the list".

Now we just need to decide how we would like to best make use of these lists.  I propose that
we keep dev@ fairly low volume so that people don’t feel the need to filter it out of their
inbox, and thus possibly miss important discussions.
If someone cares so much about the name of the list where stuff happens, then I propose we
make dev-announce@ and if that happens we can replace commits@ with dev@ below and dev@ with
dev-announce@ and start forwarding some JIRA stuff to dev@…

In order to keep dev@ low volume (but higher than it currently is, as it has mostly been “no
volume” lately) I propose the following:

Someone has a major feature that they would like to discuss.  (Again this is just for major
features, not every day bug fixes etc)
1. Make a JIRA for the thing you want to discuss (aka post the thing to commits@)
2. Post link to JIRA with a short description to dev@
3. Have a discussion on the JIRA (aka commits@) about the new thing.
4. If there is some major change/question on the JIRA that people feel needs some extra discussion/involvement
email dev@ with question and link back to the JIRA
5. Have more discussions on the JIRA (aka commits@) about the new thing.
6. If something else comes up go back too step 4.
7. During this process of decision making keep the “Title” and “Description” fields
of the JIRA (aka commits@) up to date with what is actually happening in the ticket.
8. Once things settle down make sub tasks or follow on tickets for actually implementing things
linked to the initial ticket.

That would keep the dev@ list informed of what is going on in new feature proposals, and it
will keep discussions on JIRA tickets where they are easily referenced and kept in one place,
so it is easy to get to, and easy for.
