# Stack Maintainer Team Process | ||
|
||
## Purpose of this document | ||
|
||
This guide is intended to formalize the process by which the `Stack` maintainer | ||
team operates. We expect it'll evolve over time as experience makes clearer | ||
what works best in practice. | ||
|
||
Having a well-documented set of processes and responsibilities has been | ||
instrumental in effectively maintaining the `Stackage` project across a | ||
distributed team | ||
([see the `Stackage` curators' guide | ||
](https://github.com/commercialhaskell/stackage/blob/master/CURATORS.md)) | ||
and we hope to replicate that success here. | ||
|
||
|
||
## Goals | ||
|
||
The goals of the `Stack` maintainer team are to: | ||
|
||
- Ensure that incoming bug reports and feature requests are properly triaged, | ||
answered, and/or escalated. | ||
|
||
- Provide timely review of, and feedback on, incoming pull requests. | ||
|
||
- Set up clear channels of communication for users to make support requests. | ||
|
||
- Keep Stack up-to-date with its upstream dependencies, including new GHC and | ||
Cabal releases, and libraries Stack depends on. | ||
|
||
- Increase the [bus factor](https://en.wikipedia.org/wiki/Bus_factor) of the | ||
project, encouraging more people to contribute heavily to the codebase and | ||
take ownership of it. | ||
|
||
- Make it easy to improve the documentation and test coverage of the project. | ||
|
||
The sections below detail various activities by the `Stack` team to realize | ||
these goals. | ||
|
||
|
||
## Issue triage | ||
|
||
The maintainer team provides ongoing review and responses to newly-filed GitHub | ||
issues and pull requests. From experience, we find it's easiest to have a | ||
single person "on call" at any given time. Therefore, the team rotates shifts | ||
on a weekly basis. The "on call" triager is responsible for: | ||
|
||
- Reviewing incoming issues and pull requests on GitHub. | ||
|
||
- Answering questions he/she is able to. | ||
|
||
- Merging PRs he/she feels comfortable reviewing. | ||
|
||
- Closing out irrelevant/misplaced issues. | ||
|
||
- Pulling in another maintainer to assist if necessary. | ||
|
||
The goal of the triager role is to facilitate continual, smooth progress of | ||
`Stack`'s development and to provide triagers an opportunity to become more | ||
familiar with how the project runs. | ||
|
||
This is one path to getting a lot of experience with the codebase, plus great | ||
interaction with the rest of the maintainer team, without necessarily taking on | ||
major coding tasks. | ||
|
||
|
||
## Time commitment | ||
|
||
Someone considering joining the issue triager team may be wondering: | ||
|
||
> "How large of a time investment is necessary?" | ||
That’s a great question for anyone considering taking on this role. It’s | ||
frankly somewhat uncertain right now since we’re only getting started, but we | ||
can venture a reasonable guess: | ||
|
||
We currently average about one new issue per day. Assuming that each issue | ||
entails roughly ten-to-fifteen minutes of total interaction on the part of the | ||
triager (before passing it off to someone else, answering a support question, | ||
etc) that amounts to about one or two hours spent per week being on-call. | ||
|
||
Again, these estimates will evolve over time as we settle into an optimal | ||
process, but for now we anticipate growing the team to about eight members | ||
(which is the size of the `Stackage` team as well), each of whom is likely to | ||
spend about two hours in total on upkeep work every eight weeks. | ||
|
||
|
||
## Issue and pull request interaction guidelines | ||
|
||
These guidelines apply to all members of the maintainer team. | ||
|
||
- Be courteous. | ||
|
||
- Avoid leaving issues and PRs in an ambiguous state. By default, when you | ||
respond to an issue/PR, you’re taking responsibility for shepherding it to | ||
completion. Be explicit if you’re passing it to someone else, or asking the | ||
submitter for more info/updates/etc. | ||
|
||
- Use labels, assignees, and milestones wherever possible. | ||
|
||
- If you know you’ll be unable to answer for a significant period of time, say | ||
so. Even better: ask someone else to take over from you. | ||
|
||
|
||
## Assessing feature requests and enhancement PRs | ||
|
||
**NB: this section is very likely to evolve over time as well.** | ||
|
||
A frequent source of new GitHub issues is users who would like to propose some | ||
enhancement and/or change to how `Stack` currently operates. | ||
|
||
Some of these are both small and obviously beneficial, in which case the | ||
triager should feel empowered to "green light" the idea if it makes sense to do | ||
so. | ||
|
||
If the proposal is already in the form of an actionable PR the triager may | ||
review and merge at their discretion. | ||
|
||
Oftentimes though, the request is larger and more far-reaching in nature. | ||
|
||
Perhaps the requester is unaware of the extent to which his or her change would | ||
impact other people's workflows or related components in the code. Conversely, | ||
they may have a deep understanding of its implications and feel strongly that | ||
it would be a valuable improvement, whereas it's not so clear to the triager. | ||
|
||
Discerning which requests should be considered "small" and which warrant | ||
broader collaboration is admittedly an inexact science. Use your best judgment | ||
and don't sweat the occasional mistake if you approve something you thought was | ||
small but ultimately wasn't. | ||
|
||
In the case of medium-to-large sized feature requests, it's best to solicit | ||
feedback from at least one or two of the core `Stack` developers. You may use | ||
GitHub @mentions to draw the relevant contributors' attention to the issue in | ||
question. If you're not sure who's best to consult you should ask on | ||
`#stack-collaborators`. | ||
|
||
Try to be clear to the requester that you're opening the discussion up to more | ||
participants and that the proposal will require thoughtful consideration | ||
(probably a majority vote) before any decision is made. | ||
|
||
Also remember that busy schedules, lack of complete familiarity with a given | ||
subject, strong-yet-opposing opinions held by equally rational people, and many | ||
other factors often collude to halt forward progress in arriving at firm | ||
conclusions in such situations... If at all possible, try to keep things | ||
on-track and concrete. | ||
|
||
*Regardless of feature size, bear in mind that sometimes the best answer is a | ||
respectful "no".* | ||
|
||
*If feasible, propose alternative solutions or educate the user in preference to | ||
complicating `Stack` or accepting scope-creep.* | ||
|
||
With respect to assessing a PR's code, @snoyberg has outlined some | ||
[tips for successfully getting one's work merged | ||
](https://www.snoyman.com/blog/2017/06/how-to-send-me-a-pull-request) | ||
into his projects which may be helpful to `Stack` triagers when performing | ||
reviews, as well. | ||
|
||
|
||
## Real-time communications | ||
|
||
At present, the maintainer team mostly communicates via a rather quiet channel | ||
called [`#stack-collaborators`](../CONTRIBUTING/#slack-channel) on FP | ||
Complete's Slack workspace, although we may migrate to some other platform in | ||
the near future. | ||
|
||
|
||
## Dealing with support issues | ||
|
||
We encourage users to submit support requests via GitHub issues and try to | ||
consolidate our efforts in addressing questions there. Other platforms, such as | ||
Reddit, StackOverflow, et al, may be helpful as well but the `Stack` | ||
maintainers team makes no guarantees about regularly checking them. | ||
|
||
*We may decide to offload support questions elsewhere in the future, but for | ||
now the most important thing is to direct users to a single destination.* | ||
|
||
|
||
## Old issue closing policy | ||
|
||
We have yet to settle on a precise guide for closing out old issues, but, for | ||
now, if you happen across something that could easily be marked as resolved, | ||
please do so. |
