- For example, by splitting changes to be backported into a separate commit
|
||||
from those which should not be backported, or splitting out changes which
|
||||
are more likely to cause conflicts when cherry-picked
|
||||
* Backports should be done as soon as a fix lands on the unstable branch,
|
||||
rather than waiting until when the next stable release is due and then
|
||||
backporting multiple changes from the unstable branch at once. This gives
|
||||
more opportunity for backported changes to be tested, and reduces the chance
|
||||
of backporting the wrong thing, or missing a backport.
|
||||
* These rules are not entirely prescriptive: there may be situations where
|
||||
maintainers agree that a backport is necessary even if it breaks some of
|
||||
these rules, due to the balance of fixing a critical bug vs keeping things

Issue and merge request management policy
|
||||
===
|
||||
|
||||
Aims
|
||||
---
|
||||
|
||||
* Finding duplicates and related issues and merge requests should be easy when
|
||||
triaging new ones, or when looking back at the history of a particular piece
|
||||
of code
|
||||
* GLib co-maintainers and other interested people should be able to subscribe
|
||||
to notifications for specific parts of GLib without receiving notifications
|
||||
for all activity on GLib
|
||||
* Issues and merge requests which are planned to be in a specific release
|
||||
should not be accidentally left out of that release
|
||||
* GLib co-maintainers should be able to easily see how much work is left to do
|
||||
before a release is ready
|
||||
* Users and developers should have some idea of whether an issue or merge
|
||||
request is being actively worked on, the timescale for its completion, and
|
||||
who’s working on it
|
||||
|
||||
Issue triage
|
||||
---
|
||||
|
||||
* Issues should be triaged shortly after they are filed. Triage should:
|
||||
- Add labels to categorise the issue, even if it’s about to be closed (this
|
||||
helps with finding related closed issues in future)
|
||||
- Close them immediately if they are a duplicate of an existing issue
|
||||
(`/duplicate #issue`)
|
||||
- Or if they are out of scope, such as a user support question (which should
|
||||
be on https://discourse.gnome.org)
|
||||
- Ask the user for necessary debug information if the issue is valid, a bug,
|
||||
and not enough information has been provided — extracting debug information
|
||||
from users is often time-critical because they can only reproduce an issue
|
||||
under certain conditions, or they lose interest and move on
|
||||
- Assign the issue to an upcoming milestone if it seems urgent
|
||||
* Note that triaging an issue does *not* commit the triager to working on the
|
||||
issue
|
||||
* If an issue is likely to affect a stable release (as well as the unstable
|
||||
`main` branch), assign it to the next micro release milestone for that stable
|
||||
release — the merge request for the fix will be assigned to the next `main`
|
||||
micro release, and its backport to the next stable micro release
|
||||
|
||||
Merge request triage
|
||||
---
|
||||
|
||||
* Merge requests should be triaged shortly after they are filed. Triage should
|
||||
proceed as for issues, including labels and milestones
|
||||
* The milestone for a merge request is the release it is intended to be
|
||||
included in, and it should match the target branch of the merge request
|
||||
- It’s important to add milestones to merge requests, as they then show up on
|
||||
the milestone page and highlight that the release is not yet ready until
|
||||
they’re all merged
|
||||
- This prevents releases accidentally being made without containing all the
|
||||
fixes they’re supposed to
|
||||
* The ‘assignee’ of the merge request is the person who is working on it,
|
||||
responding to review feedback
|
||||
* The ‘reviewer’ of the merge request is the GLib co-maintainer who is actively
|
||||
reviewing it
|
||||
* Don’t assign someone else as the reviewer or assignee of a merge request
|
||||
unless they have said they are willing to do it, otherwise it gives a false
|
||||
impression that their time is allocated for doing the work
|
||||
- You may assign someone else as a reviewer or assignee when closing or
|
||||
merging a merge request, though, if that helps document who has done the
|
||||
work so they can be appropriately attributed
|
||||
|
||||
Labelling issues and merge requests
|
||||
---
|
||||
|
||||
GLib has a huge number of labels available, one per component of the library
|
||||
plus several orthogonal labels. The use of labels allows for:
|
||||
* Easy searching for related issues and duplicates, by filtering on label
|
||||
* Co-maintainers of GLib to subscribe to issue and merge request notifications
|
||||
for a set of labels limited to their interests, meaning they don’t have to
|
||||
subscribe to the full fire hydrant of GLib notifications just to maintain one
|
||||
or two components
|
||||
* High-level prioritization of work, such as prioritizing crashes over new
|
||||
features
|
||||
* Tracking issues and merge requests through the release lifecycle, so that
|
||||
(for example) API additions can be done before the API freeze, and merge
|
||||
requests approved during a code freeze can all be landed when the freeze ends
|
||||
|
||||
To subscribe to a specific label, go to
|
||||
[the labels page](https://gitlab.gnome.org/GNOME/glib/-/labels) and use the
|
||||
subscription selector next to the labels you’re interested in.
|
||||
|
||||
Several labels are worth highlighting:
|
||||
* Security: Time-critical security issues, which should typically be marked
|
||||
as confidential.
|
||||
* Merge After Freeze: Merge requests which have been accepted, but which can’t
|
||||
be merged yet as GLib is in
|
||||
[code freeze](https://wiki.gnome.org/ReleasePlanning/Freezes). All MRs tagged
|
||||
like this will be merged en-masse when the freeze ends.
|
||||
* Needs Information: Issues which are blocked due to needing more information
|
||||
from the reporter. These can be closed after 4 weeks if the reporter does not
|
||||
respond.
|
||||
* Not GNOME / Out of Scope: Issues which were closed due to not being within
|
||||
the scope of GLib.
|
||||
* Newcomers: Issues which are suitable for being taken on by newcomers to GLib.
|
||||
When labelling an issue as such, please make sure that the issue title is
|
||||
clear, and the description (or a comment) clearly explains what needs to be
|
||||
done to fix the issue, to give newcomers the best chance of successfully
|
||||
submitting a fix.
|
||||
* Translation / I18N: Issues which relate to translatable strings or other
|
||||
internationalization or localization problems. Adding this label may cause
|
||||
the translation team to be looped into an issue or merge request.
|
||||
* API deprecation: Issues or merge requests which deprecate GLib API, and hence
|
||||
can only land in an unstable release outside an
|
||||
[API freeze](https://wiki.gnome.org/ReleasePlanning/Freezes).
|
||||
* New API: Issues or merge requests which add new GLib API, and hence can only
|
||||
land in an unstable release outside an
|
||||
[API freeze](https://wiki.gnome.org/ReleasePlanning/Freezes).
|
||||
* Intermittent: Issues (such as test failures) which can only be reproduced
|
||||
intermittently.
|
||||
* Test failure: Issues which revolve around a unit test failing. Typically
|
||||
these are opened after a CI run has failed, and are useful for tracking how
|
||||
often a particular failure happens.
|
||||
* Test missing: Merge requests which need a unit test to be written before they
|
||||
can be merged.
|
||||
|
||||
Merge request review
|
||||
---
|
||||
|
||||
* Assign yourself as the ‘reviewer’ of a merge request when you start review;
|
||||
this helps with tracking notifications, and lets the assignee of the merge
|
||||
request know whether you are providing a comprehensive review or just some
|
||||
drive-by comments
|
||||
* Review the merge request at a high level first: is the change needed, does
|
||||
it make sense, is it structured correctly; then look at the detail of memory
|
||||
management, typos, etc.
|
||||
- If a merge request is large or contains multiple unrelated changes, it is
|
||||
best to ask the author to split it into multiple parallel merge requests.
|
||||
This prevents review comments on one part of the merge request from blocking
|
||||
merging the rest, and allows the reviewer’s time to be split into smaller
|
||||
and more manageable chunks.
|
||||
* Submit all your comments as a single review (rather than adding multiple
|
||||
single comments) to avoid spamming subscribers with multiple notifications.
|
||||
* CC in additional reviewers if their second opinion or domain expertise are
|
||||
needed.
|
||||
* Follow the review through multiple cycles of updates and re-review with an
|
||||
aim to getting the merge request landed — a merge request which gets one
|
||||
round of review and which is then forgotten about is as useful as a merge
|
||||
request which gets no review at all.
|
||||
* While it is useful to highlight related areas of the code needing work that
|
||||
you spot while doing a review, it is not the responsibility of the author of
|
||||
a merge request to fix things outside the scope of their merge request.
|
||||
Reviews which increase the scope of work for a merge request make it much
|
||||
less likely that the merge request will land quickly, which reduces the
|
||||
effective usefulness of the contribution. This wears down contributors and
|
||||
reviewers, as they don’t see closure on what they’ve put time into. It is
|
||||
better to file additional issues for follow-up or related work.
|
||||
* If you cannot follow through a merge request to completion, unassign yourself
|
||||
as the reviewer to make this clear to everybody.
|
||||
* Once a merge request lands, a backport might need to be created for the most
|
||||
recent stable GLib branch (see the [backport policy](./backports.md). It is
|
||||
the responsibility of the maintainers to do this, not the responsibility of
|
||||
the merge request author.
