PYTHONBREAKPOINT has been exposed as an environment variable in
the openedx Dockerfile available to be changed in config.yml. The docs have also been changed to recommend using
breakpoint and explaining how PYTHONBREAKPOINT can be modified to use a
custom debugger.

This issue was reported upstream here: https://github.com/celery/celery/issues/6302
It is caused by the `tty: true` statement, for some reason. It will be fixed in
Nutmeg, after celery is upgraded to 5.2.6.
Close #681.
- [Security] Apply logout redirect url security fix. (by @regisb)
- [Feature] Make it possible to force the rendering of a given template, even when the template path matches an ignore pattern. (by @regisb)
- 💥[Fix] Get rid of the `tutor config render` command, which is useless now that themes can be implemented as plugins. (by @regisb)
When rendering theme files in a plugin, the *.scss files are stored in a
"partials" subdirectory, which was ignored by the environment rendering logic.
To render these files, we move the path ignoring logic to a filter, which is a
list of regular expressions. Values in this filter can be overridden by another
filter.

- [Fix] Fix updates for the Caddy deployment in multi-node Kubernetes clusters (#660). Previously, Caddy configuration updates might fail if the Kubernetes cluster had more than one worker node. (by @fghaas)
When running multiple concurrent versions of a plugin there are sometimes
version conflicts that prevent the plugin from being loaded. Prior to v1, Tutor
was correctly ignoring plugins that could not be loaded. During the transition
to v1 we lost that feature because we only captured TutorErrors.
When a Pod associated with a Deployment is updated (for example, due
to a change to its ConfigMap, or an updated image reference),
Kubernetes uses a ReplicaSet to spin up a Pod with the new
configuration, and once it is up, it tears down the old one.
In case of the Caddy Deployment, this is complicated by the fact that
it uses a Persistent Volume Claim (PVC), whose corresponding volume
uses a Read/Write-Once (RWO) configuration. This means that it can
only be used by multiple Pods if all those Pods all run on the same
Kubernetes worker node.
In order to enable rolling upgrades for the Caddy Deployment, we need
to ensure that its replacement Pod is scheduled on the same node as
the original Pod.
Thus, add a pod affinity rule that will force exactly that behavior.
Reference:
https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/
The other Tutor services that use volumes (MySQL, Redis, Elasticsearch
and MongoDB) do not need this fix, since they all use the "Recreate"
deployment strategy: their Pods are all automatically torn down before
being replaced. This strategy is not needed for Caddy, and using a pod
affinity rule is less disruptive to the learner experience.
With this change, we want to better highlight the contributions of
developers to Tutor. We want to publicly acknowledge the positive impact
that individuals and companies have on the development of the platform.
to that end, each changelog entry can now be suffixed with the name of
the author (individual or company) who authored the change. These names
will find their way to the release notes for every release. Eventually,
we also want to spread these release notes more widely. For instance, we
could post new releases to the forum to notify the community of
important changes.
If you have contributed to Tutor in the past, feel free to open a PR and
append your name to the changes that you made. We will not be able to
update the release notes for every release out there, but your
contributions will be acknowledged from the changelog.
When mounting a directory in a dev-only container, such as the
"learning" mfe, docker-compose is failing because it is attempting to
run "docker-compose stop" in the local context -- which knows nothing
about the learning container.
To resolve this, we store tmp volumes either in the local or dev
docker-compose.yml, and load either one depending on the context.
- [Improvement] Add the `COMPOSE_PROJECT_STARTED` action and run `dev
stop` on `local start` (and vice versa).
- [Feature] Introduce `local/dev copyfrom` command to copy contents from
a container.
- [Bugfix] Fix a race condition that could prevent a newly provisioned
LMS container from starting due to a `FileExistsError` when creating
data folders.
- [Deprecation] Mark `tutor dev runserver` as deprecated in favor of
`tutor dev start`. Since `start` now supports bind-mounting and
breakpoint debugging, `runserver` is redundant and will be removed in a
future release.
- [Improvement] Allow breakpoint debugging when attached to a service
via `tutor dev start SERVICE`.
- [Security] Apply rate limiting security fix (see
[commit](b5723e416e)).
- [Feature] Introduce the ``-m/--mount`` option in ``local`` and ``dev``
commands to auto-magically bind-mount folders from the host.
- [Feature] Add `tutor dev quickstart` command, which is similar to
`tutor local quickstart`, except that it uses dev containers instead
of local production ones and includes some other small differences for
the convience of Open edX developers. This should remove some friction
from the Open edX development setup process, which previously required
that users provision using local producation containers (`tutor local
quickstart`) but then stop them and switch to dev containers (`tutor
local stop && tutor dev start -d`).
- 💥[Improvement] Make it possible to run `tutor k8s exec <command with
multiple arguments>` (#636). As a consequence, it is no longer
possible to run quoted commands: `tutor k8s exec "<some command>"`.
Instead, you should remove the quotes: `tutor k8s exec <some command>`.
- 💥[Deprecation] Drop support for the `TUTOR_EDX_PLATFORM_SETTINGS`
environment variable. It is now recommended to create a plugin
instead.
- 💥[Improvement] Complete overhaul of the plugin extension mechanism.
Tutor now has a hook-based Python API: actions can be triggered at
different points of the application life cycle and data can be modified
thanks to custom filters. The v0 plugin API is still supported, for
backward compatibility, but plugin developers are encouraged to migrate
their plugins to the new API. See the new plugin tutorial for more
information.
- [Improvement] Improved the output of `tutor plugins list`.
- [Feature] Add `tutor [dev|local|k8s] status` command, which provides
basic information about the platform's status.
Running `local start` while a dev platform is still running is a common sourse
of mistakes. Here we introduce a new action to automatically stop local and dev
projects whenever a project with a different name is started.
`copyfrom` copies data from a container to the local filesystem. It's similar
to bindmount, but less clunky, and more intuitive. Also, it plays along great
with `--mount`. Eventually we'll just get rid of the `bindmount` command and
the `--volume` option.
`tutor dev runserver` will be removed in a future release.
Developers are encouraged to use `tutor dev start` instead,
which is more flexible and provides a consistent interface
with `tutor local start`.
As part of this deprecation, we enable the `tty` and
`stdin_open` options on development docker-compose
services. This will allow developers to use `start`
for breakpoint debugging, which was previously only
availble via `runserver`. Several parallel PRs have
been merged in order to make the same change in the
development services of the official plugins.
Although `start` does not support the `--volume` option,
it supports a more-powerful `--mount` option. So, where
developers previously used:
tutor dev runserver --volume ...
to bind-mount host directories, they should now use:
tutor dev start --mount ...
Resolves https://github.com/overhangio/2u-tutor-adoption/issues/61
The `--mount` option is available both with `tutor local`
and `tutor dev` commands. It allows users to easily bind-mount containers from
the host to containers. Yes, I know, we already provide that possibility with
the `bindmount` command and the `--volume=/path/` option. But these suffer from
the following drawbacks:
- They are difficult to understand.
- The "bindmount" command name does not make much sense.
- It's not convenient to mount an arbitrary folder from the host to multiple
containers, such as the many lms/cms containers (web apps, celery workers and
job runners).
To address this situation, we now recommend to make use of --mount:
1. `--mount=service1[,service2,...]:/host/path:/container/path`: manually mount
`/host/path` to `/container/path` in container "service1" (and "service2").
2. `--mount=/host/path`: use the new v1 plugin API to discover plugins that
will detect this option and select the right containers in which to bind-mount
volumes. This is really nifty...

Add `tutor dev quickstart` command, which is equivalent to
`tutor local quickstart`, but uses dev containers instead
of local production ones and includes some other small
differences for the convience of Open edX developers.
This should remove some friction
from the Open edX development setup process, which previously

Fixes overhangio/2u-tutor-adoption#58
The entrypoint in the "openedx" Docker image was used only to define the
DJANGO_SETTINGS_MODULE environment variable, based on SERVICE_VARIANT and
SETTINGS. We ditch SETTINGS in favour of defining explicitely
DJANGO_SETTINGS_MODULE.
The problem with the Docker entrypoint is that it was bypassed whenever we ran
`tutor local exec` or `tutor k8s exec`. By removing it we make it simpler for
end-users to run manage.py commands in kubernetes.
This is a very large refactoring which aims at making Tutor both more
extendable and more generic. Historically, the Tutor plugin system was
designed as an ad-hoc solution to allow developers to modify their own
Open edX platforms without having to fork Tutor. The plugin API was
simple, but limited, because of its ad-hoc nature. As a consequence,
there were many things that plugin developers could not do, such as
extending different parts of the CLI or adding custom template filters.
Here, we refactor the whole codebase to make use of a generic plugin
system. This system was inspired by the Wordpress plugin API and the
Open edX "hooks and filters" API. The various components are added to a
small core thanks to a set of actions and filters. Actions are callback
functions that can be triggered at different points of the application
lifecycle. Filters are functions that modify some data. Both actions and
filters are collectively named as "hooks". Hooks can optionally be
created within a certain context, which makes it easier to keep track of
which application created which callback.
This new hooks system allows us to provide a Python API that developers
can use to extend their applications. The API reference is added to the
documentation, along with a new plugin development tutorial.
The plugin v0 API remains supported for backward compatibility of
existing plugins.
Done:
- Do not load commands from plugins which are not enabled.
- Load enabled plugins once on start.
- Implement contexts for actions and filters, which allow us to keep track of
the source of every hook.
- Migrate patches
- Migrate commands
- Migrate plugin detection
- Migrate templates_root
- Migrate config
- Migrate template environment globals and filters
- Migrate hooks to tasks
- Generate hook documentation
- Generate patch reference documentation
- Add the concept of action priority
Close #499.
Previously, the `k8s exec` command did not support unknown "--options". This
made it impossible to launch, say, a django shell in the lms container.
While implementing this feature we saw an opportunity to simplify the way jobs
are handled in the k8s commands.
Close #636.

- [Security] Apply SAML security fix.
- [Improvement] In addition to the Docker build arguments
`EDX_PLATFORM_REPOSITORY` and `NPM_REGISTRY`, also support two corresponding
and identically-named `config.yml` values serving the same purpose.
Previously, the only way for Tutor users to use a fork of edx-platform
or a custom NPM registry was to use build args during the image build.
This is suboptimal in the case of automatically building images from
CI pipelines, which may want to auto-detect when an image needs to be
rebuilt based on config.yml changes.
In addition, the EDX_PLATFORM_VERSION build argument can already be
set via a corresponding config.yml parameter (OPENEDX_COMMON_VERSION),
so it's reasonable to follow that precedent and also introduce
config.yml parameters to correspond with the EDX_PLATFORM_REPOSITORY
and NPM_REGISTRY build arguments.
Thus, introduce two new configuration parameters:
- EDX_PLATFORM_REPOSITORY
- NPM_REGISTRY
These parameters can now optionally be used instead of the
aforementioned build args.
