Now that the mypy bugs have been resolved, we are able to define more precisely
and cleanly the types of Actions and Filters.
Moreover, can now strongly type named actions and hooks (in consts.py). With
such a strong typing, we get early alerts of hooks called with incorrect
arguments, which is nothing short of awesome :)
This change breaks the hooks API by removing the `context=...` argument. The
reason for that is that we cannot insert arbitrary arguments between `P.args,
P.kwargs`: https://peps.python.org/pep-0612/#the-components-of-a-paramspec
> A function declared as def inner(a: A, b: B, *args: P.args, **kwargs:
> P.kwargs) -> R has type Callable[Concatenate[A, B, P], R]. Placing
> keyword-only parameters between the *args and **kwargs is forbidden.
Getting the documentation to build in nitpicky mode is quite difficult... We
need to add `nitpick_ignore` to the docs conf.py, otherwise sphinx complains
about many missing class references. This, despite upgrading almost all doc
requirements (except docutils).
We introduce a new filter to implement custom commands in arbitrary containers.
It becomes easy to write convenient ad-hoc commands that users will
then be able to run either on Kubernetes or locally using a documented CLI.
Pluggable jobs are declared as Click commands and are responsible for
parsing their own arguments. See the new CLI_DO_COMMANDS filter.

`quickstart` is being renamed to `launch` and deprecated in favor of
using `launch`. The `quickstart` function temporarily aliases to
`launch`. Further mentions of `quickstart` have been changed to
reference `launch` instead.
We are indicating that this change is breaking 💥 to encourage people to
migrate their scripts right away!
Currently there is no way for plugins to customize Kubernetes resources
defined in Tutor deployment manifests.
This change makes that possible by taking advantage of the strategic
merge patching mechanism in `kustomization.yml`.
Any resource definition in a `k8s-override` patch in a plugin will
override the resource defined by Tutor, provided that their names match.

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.

- 💥 [Feature] Upgrade to Nutmeg: (by @regisb)
- 💥 [Feature] Persistent grades are now enabled by default.
- [Bugfix] Remove edX references from bulk emails ([issue](https://github.com/openedx/build-test-release-wg/issues/100)).
- [Improvement] For Tutor Nightly (and only Nightly), official plugins are now installed from their nightly branches on GitHub instead of a version range on PyPI. This will allow Nightly users to install all official plugins by running ``pip install -e ".[full]"``.
- [Bugfix] Start MongoDB when running migrations, because a new data migration fails if MongoDB is not running
I noticed `pip uninstall -y tutor` will not uninstall the plugins, so I made this PR. I know it's ugly, but I don't find any other way of doing it. Let me know if there are better choices 😊
Now that Tutor is the official community installation for Open edX, it no
longer makes sense to host a forum that is separate from the general Open edX
forum. Moving conversations there will encourage cross-communication between
projects and maintainers. This change is part of a larger overhaul described in
this Tutor enhancement proposal (TEP):
https://discuss.overhang.io/t/tep-rethinking-the-tutor-maintainers-program/2724
In the future, plugin maintainers should point their users to the Open edX
forum as well. They are encouraged to create dedicated "tutor-pluginnname" tags
on the forum and to set their notification level to "watching".
The default user in the mysql container is 'mysql',
so the `mysql` command tries to use the 'mysql' MySQL user by default.
But, in the MySQL dump instructions,
we are providing the MySQL root user's password, so we need
to specify `MYSQL_ROOT_USERNAME` as the MySQL user when invoking `mysql`.
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
required that users provision using local producation
containers but then stop them and switch to dev containers:
* tutor local quickstart
* tutor local stop
* tutor dev start -d
Document the command and its improved workflow in

Previously, it was possible to override settings by defining the
TUTOR_EDX_PLATFORM_SETTINGS environment variable. But let's face it:
- It was not very well supported.
- It was poorly explained.
- It was not very useful.
- It causes unnecessary code complexity.
For these reasons, we drop that feature.
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.
PR #619 set the EDX_PLATFORM_VERSION build arg's default to
OPENEDX_COMMON_VERSION. While this works fine for setting a
non-default branch to run edx code from (say, "master"), it may break
if the user sets OPENEDX_COMMON_VERSION to a branch or tag name that
does not exist upstream in repositories *other than*
EDX_PLATFORM_REPOSITORY.
Thus, introduce a separate configuration parameter,
EDX_PLATFORM_VERSION, to match the build arg of the same name. Set its
default to OPENEDX_COMMON_VERSION.
This way, the user can deploy an arbitrarily-named fork of
edx-platform, while retaining the default OPENEDX_COMMON_VERSION
(like, for example "open-release/maple.3") for everything else.
The docs recommend commands like:
pip install tutor[full]
pip install -e ./tutor[full]
for installing Tutor. These work fine in bash. For zsh,
though, which is now the default on macOS, quotes are
needed, otherwise zsh will interpret the brackets as
special syntax:
pip install "tutor[full]"
pip install -e "./tutor[full]"
Caveat: I have not tested this myself since I don't
own a Mac, but I've read several issue reports to this
effect, such as:
https://github.com/pypa/pipenv/issues/2830#issuecomment-419593199
The full installation will include all the plugins that
come bundled with Tutor stable. This is made possible by
a recent change to Tutor Nightly
(https://github.com/overhangio/tutor/pull/626).
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.
I found the existing docs a bit light on the particulars
of how the YAML and Python plugin APIs relate. I was
able to figure it out (there's a nice congruence
between them) but I think these tweaks should it make
it more immediately obvious to readers how the Python
API is a essentially a superset of the YAML API that
allows for dynamic behavior.
because it only contains CLI reference information currently.
The folder structure implies that eventually there will be
more reference material, so the name of 'reference.rst'
was *not* changed to 'cli-reference.rst'.
