Triaging
==========
About
=====
The purpose of `issue triage process
<https://en.wikipedia.org/w/index.php?title=Software_bug&redirect=no#Bug_management>`_
is to make sure all the Invenio issues and tasks are well described, sorted out
according to priorities into timely milestones, and that they have well assigned
a responsible person to tackle them. The triage process is done collectively by
the representatives of various Invenio distributed teams. The triage team
members make sure of the big picture, cross-consider issues and tasks among
interested services, help to note down, understand, prioritise, and follow-upon
them.
Triaging team
=============
Invenio triaging team consists of persons who manipulate issues,
create labels, attribute assignments, follow up progress, and
collaboratively decide on milestones for various Invenio projects on
GitHub.
To enter a triaging team, the following conditions must be met:
1. The person is an established Invenio scrum master or developer who
knows well the wider project ecosystem. E.g. worked for more than
N1 years on the project OR maintained more than N2 modules OR
committed more than N3 lines of code to N4 different modules. (For
respectably large values of N.)
2. The person will use triaging rights for manipulating tickets only;
never for pushing code. Since GitHub ticket-manipulation rights
are indistinguishable from GitHub code-pushing rights, the persons
in the "Triagers" team should take extra care to avoid accidental
mishaps in this direction. (Such as doing ``git push myorigin
master -f`` and realising only afterwards that "oops myorigin was
wrongly set so now I have accidentally replaced the whole Invenio
canonical project commit history".) The code pushing is being done
by the "Integrators", not by the "Triagers".
3. The person will endorse social contract related to participation in
the collaborative consensual triaging and milestone decision-making
process. The triaging team will represent various Invenio
developer teams and services, participating together with the
release management team on decisions related to the roadmap
milestones and releases.
Triaging process
================
The process of triaging issues is being done continuously. This
usually means that labels are being attached to issues, assignments
are being decided, progress is being tracked, dependencies being
clarified, questions being answered, etc.
The triaging team meets regularly (say once every 1-2 weeks) to go
over the list of open issues for any catch-up, follow-up, and
re-classification of issues with respect to milestones.
Issue labels
============
The issues are attributed namespaced labels indicating the following
issue properties:
* type:
- `t_bug`: bug fix
- `t_enhancement`: new feature or improvement of existing feature
* priority:
- `p_blocker`: highest priority, e.g. breaks home page
- `p_critical`: higher priority, e.g. test case broken
- `p_major`: normal priority, used for most tickets
- `p_minor`: less priority, less visible user impact
- `p_trivial`: lowest priority, cosmetics
* component:
- `c_WebSearch`: search component
- `c_WebSubmit`: submit component
- etc
* status:
- `in_work`: developer works on the topical branch
- `in_review`: reviewer works on reviewing the work done
- `in_integration`: integrator works on checking interplay with other services
* resolution:
- `r_fixed`: issue fixed
- `r_invalid`: issue is not valid
- `r_wontfix`: issue will not be dealt with for one reason or another
- `r_duplicate`: issue is a duplicate of another issue
- `r_question`: issue is actually a user question
- `r_rfc`: issue is actually an open RFC
* branch:
- `maint-x.y`: issue applies to Invenio maint-x.y branch
- `master`: issue applies to Invenio master branch
- `next`: issue applies to Invenio next branch
- `pu`: issue applies to Invenio pu branch
* version:
- `v0.99.1`: issue was observed on version v0.99.1
- `v1.1.3`: issue was observed on version v1.1.3
- etc
The label types and values are coming from our Trac past and may be
amended e.g. to take into account new component names in Invenio v2.0.
Milestones and releases
=======================
Issues may be attributed milestones that are closely related with
feature-dependent and/or time-dependent release schedule of Invenio
releases.
There are two kinds of milestones: "release-oriented" milestones (say
v1.1.7) and "someday" milestones (say v1.1.x) for each given release
series (v1.1 in this case). The release-oriented milestones may have
dates attached to them; the someday milestone may not.
Typically, a new issue is given (a) the closest milestone in the given
release series if its urgency is high, or (b) a later milestone in the
given release series depending on the estimated amount of work and
available resources, or is (c) left in the catch-all someday milestone
out of which the issue can be later cherry-picked and moved to one of
the concrete release-oriented milestones depending on available
resources.
Example: after Invenio v1.4.0 is released, all incoming bug reports
for this version will go to the "someday" milestone for this release
series, i.e. to "v1.4.x". A new XSS vulnerability issue will go
straight to the next milestone "v1.4.1" because its release is urgent.
A typo in an English output phrase in the basket module will remain in
the someday milestone "v1.4.x" until it is picked for one of later
releases, say v1.4.7, depending on available resources in the basket
team.
The triaging team together with the release management team will
periodically review issues in a given release series and decide upon
the set of issues going into a concrete release-oriented milestone
(say these 15 issues for v1.4.1 milestone) after which the issue set
is freezed and a sprint may be co-organised to meet the target
deadline. Once all the issues have been solved, a new Invenio bug-fix
release v1.4.1 is published and the release-oriented triaging cycle
starts anew with v1.4.2.
(Note that someday milestones are usually more useful for new feature
releases; they might remain relatively empty for bug fix releases.)
