- [Bugfix] Fix authentication in development due to missing SameSite policy on session ID cookie.
- [Bugfix] Display properly themed favicon.ico image in LMS, Studio and microfrontends.
- [Bugfix] Fix "LazyStaticAbsoluteUrl is not JSON serializable" error when sending bulk emails.
- [Bugfix] Fix `tutor local importdemocourse` fails when platform is not up.
In development, it was no longer possible to authenticate to the lms. Ater
signing in, the session ID could not be dropped, and thus the user was not
signed in, although no error was logged -- just a warning in the browser
console.
This problem was caused by the fact that the SameSite policy was set to "None"
in development.
Previously, we were redirecting all /*favicon.ico requests to the default
favicon. This meant that the favicon might not necessarily be correctly themed,
most notably in MFEs. Here, we resolve this issue by redirecting to the
theme-agnostic theming/asset/* url. Also, we restrict the overly generic regexp
for favicon url matching. We verified that we did not miss any url by running
the following command on the demo server:
tutor local logs caddy | grep --only-matching "host.*favicon.ico" | sort | uniq
The LazyStaticAbsoluteUrl object was breaking bulk emails again with the
following stacktrace:
2022-01-11 13:50:10,591 ERROR 12 [celery.app.trace] [user None] [ip None] trace.py:255 - Task lms.djangoapps.instructor_task.tasks.send_bulk_course_email[26b93357-018a-408f-b3f7-b69722447c5b] raised unexpected: EncodeError(TypeError('Object of type LazyStaticAbsoluteUrl is not JSON serializable'))

The point of that lazy object was to link to the lms logo even when a custom
theme was enabled. Luckily, we no longer need this lazy evaluation because we
now have theme-agnostic urls that point to static asset (see
https://github.com/openedx/edx-platform/pull/29461).

upgrading.
- [Bugfix] During upgrade, make sure that environment is up-to-date
prior to prompting to rebuild the custom images.
- [Bugfix] Fix ownership of mysql data, in particular when upgrading a
Kubernetes cluster to Maple.
- [Bugfix] Ensure that ``tutor k8s upgrade`` is run during ``tutor k8s
quickstart``, when necessary.
- 💥[Bugfix] By default, detect the current version during ``tutor
k8s/local upgrade``.
- [Bugfix] Fix upgrading from Lilac to Maple on Kubernetes by deleting
deployments and services.
`upgrade` had several issues, which are summarized here:
https://discuss.overhang.io/t/confusing-instructions-during-upgrade/2281/7
- The docs say that you should run quickstart, but what most people will see is
the big command tutor local upgrade --from=lilac verbatim paragraph.
- The local upgrade command should be very explicit about the fact that users
need to run quickstart.
- Maybe the name of the local upgrade command should be improved.
- When upgrading tutor from one major release to the next, there should be a
more explicit warning to inform users of what they are doing (see this other
conversation 1)
- We should tell people that they almost certainly need to enable the tutor and
the mfe plugins, if they are not enabled during upgrade.
- A link to all of the breaking changes from the changelog should be
prominently displayed during upgrade.
- The docs should emphasize that upgrading from one major release to the next
is potentially a risky endeavor and that downgrading is not possible. The docs
should also link to the changelog.
This commit has grown slightly beyond the intended scope, but the changes should be mostly positive.
In theory, we can assign ownership of mysql data to just any user. But in
Lilac, mysql was running with user 999. When upgrading to Maple, on Kubernetes,
the fsGroupChangePolicy was causing a change of the data *group* (to 1000) but
not of the user. This was causing a crash with the following error:
[ERROR] InnoDB: The error means mysqld does not have the access rights to the directory.
When upgrading from Lilac, all services break with the following error:
Service "***" is invalid: spec.ports[0].nodePort: Forbidden: may not be used when `type` is 'ClusterIP'
Upgrading deployments fails as well:
Deployment.apps "***" is invalid: spec.selector: Invalid value: v1.LabelSelector{MatchLabels:map[string]string{"app.kubernetes.io/instance":"openedx-********", "app.kubernetes.io/managed-by":"tutor", "app.kubernetes.io/name":"***", "app.kubernetes.io/part-of":"openedx"}, MatchExpressions:[]v1.LabelSelectorRequirement(nil)}: field is immutable
That's because deployments and services need to be deleted as part of the Maple
upgrade. So that's what we do as part of `tutor k8s upgrade --from=lilac`. And
we take the opportunity to:
1. Run upgrade as part of quickstart, when necessary.
2. Default to lilac during `tutor k8s upgrade`.
Close #551.
- [Security] Upgrade Django to 3.2.11 in edx-platform.
- [Security] Prevent non-staff users from searching usernames by email by
abusing the logout url.
Without this patch, it is possible to search for account info including
username by using the email of a learner. This fix disallows searching using
email by regular users and restricts this feature to only staff and superusers.
- A shared cookie domain between lms and cms is no longer recommended:
https://github.com/edx/edx-platform/blob/master/docs/guides/studio_oauth.rst
- refactor: clean mounted data folder in lms/cms. In Lilac, the
bind-mounted lms/data and cms/data folders are a mess because new
folders are created there for every new course organisation. These
folders are empty. As far as we know they are useless... With this
change we move these folders to a dedicated "modulestore" subdirectory;
which corresponds better to the initial intent of the fs_root setting.
- fix: frontend failure during login to the lms. See:
https://github.com/openedx/build-test-release-wg/issues/104
- feat: move all forum-related code to a dedicated plugin. Forum is an
optional feature, and as such it deserves its own plugin. Starting from
Maple, users will be able to install the forum from
https://github.com/overhangio/tutor-forum/
- migrate from DCS_* session cookie settings to SESSION_*. That's
because edx-platform no longer depends on django-cookies-samesite. Close
https://github.com/openedx/build-test-release-wg/issues/110
- get rid of tons of deprecation warnings in the lms/cms
- feat: make it possible to point to themed assets. Cherry-picking this
change makes it possible to point to themed assets with a theme-agnostic
url, notably from MFEs.
- Install all official plugins as part of the `tutor[full]` package.
- Don't print error messages about loading plugins during autocompletion.
- Prompt for image building when upgrading from one release to the next.
- Add `tutor local start --skip-build` option to skip building Docker images.
Close #450.
Close #545.
This introduces quite a few changes to make it easier to run Caddy as a load
balancer in Kubernetes:
- Make it possible to start/stop a selection of resources with ``tutor k8s
start/stop [names...]``.
- Make it easy to deploy an independent LoadBalancer by converting the caddy
service to a NodePort when ``ENABLE_WEB_PROXY=false``.
- Add a ``app.kubernetes.io/component: loadbalancer`` label to the LoadBalancer
service.
- Add ``app.kubernetes.io/name`` labels to all services.
- Preserve the LoadBalancer service in ``tutor k8s stop`` commands.
- Wait for the caddy deployment to be ready before running initialisation jobs.
Close #532.
On some providers (notably: DigitalOcean) NodePort services are not exposed to
the outside world. But this is not what the Kubernetes spec describes:
https://kubernetes.io/docs/concepts/services-networking/service/#publishing-services-service-types
Thus, there is a risk that NodePort services are exposed to the outside world
in some context. To avoid this, we convert all NodePort to ClusterIP resources.
Previously, configuration management was very confusing because we kept mixing
"base" and "defaults" configuration:
- It was difficult to make the difference between core settings that were
necessary (e.g: passwords) as opposed to others that could simply be
defaulted to.
- The order of settings in config.yml mattered: config entries that depended on
other needed to be defined later. As a consequence, Tutor was not compatible
with Python 3.5, where dict entries are not sorted.
Python 3.5 has reached end of life in September 3.5. Anyway, Tutor was not
compatible because some dev dependencies, such as astroid 2.8.3, are no longer
available in 3.5.
This means that we can now start using many python 3.6 niceties, such as
f-strings \o/
Through the commonLabels directive in kustomization.yml, all resources
get a label named "app.kubernetes.io/version", which is being set to
the Tutor version at the time of initial deployment.
When the user then subsequently progresses to a new Tutor version,
Kubernetes attempts to update this label — but for Deployment,
ReplicaSet, and DaemonSet resources, this is no longer allowed as of
https://github.com/kubernetes/kubernetes/issues/50808. This causes
"tutor k8s start" (at the "kubectl apply --kustomize" step) to break
with errors such as:
Deployment.apps "redis" is invalid: spec.selector: Invalid value: v1.LabelSelector{MatchLabels:map[string]string{"app.kubernetes.io/instance":"openedx-JIONBLbtByCGUYgHgr4tDWu1", "app.kubernetes.io/managed-by":"tutor", "app.kubernetes.io/name":"redis", "app.kubernetes.io/part-of":"openedx", "app.kubernetes.io/version":"12.1.7"}, MatchExpressions:[]v1.LabelSelectorRequirement(nil)}: field is immutable
Simply removing the app.kubernetes.io/version label from
kustomization.yml will permanently fix this issue for newly created
Kubernetes deployments, which will "survive" any future Tutor version
changes thereafter.
However, *existing* production Open edX deployments will need to throw
the affected Deployments away, and re-create them.
Also, add the Tutor version as a resource annotation instead, using
the commonAnnotations directive.
