See the discussion here: https://github.com/overhangio/tutor/pull/984
And the upstream PR here: https://github.com/openedx/edx-platform/pull/34210
The tl;dr is that the Redis course structure cache was growing without
bounds. While the upstream fix should resolve that issue, we decided
that Tutor should have a maxmemory limit and an eviction policy set for
operational safety.
Thus, Redis now has a 4gb maxmemory. If you need more memory on your
instance, you should implement the "redis-conf" patch.
To manually expire existing keys, run:
tutor local run cms ./manage.py cms shell -c "from django.core.cache import caches; c = caches['course_structure_cache']; [c.expire(key, 604800) for key in c.keys('*')]"
The LMS was overriding CMS_BASE properly, but Studio (CMS) configuration
was not. That meant that Studio's CMS_BASE in dev mode was using the
devstack default of localhost:18010 (because this is what's defined in
edx-platform). This in turn broke parts of Studio that use this value,
such as the XBlock v2 API (/api/xblock/v2).
This commit derives the value of the CMS_BASE Django setting from
Tutor's CMS_HOST config value, in the same way that the LMS does it.
This fix is for a rather serious issue that affects users who upgrade
from Olive to Palm. The client mysql charset and collation was
incorrectly set to utf8mb4, while the server stil runs utf8mb3. Only
users who run the mysql container are affected.
To resolve this issue, we explicitely configure the client to use the
utf8mb3 charset/collation.
Important note: users who have somehow managed to upgrade from olive to
Palm before may find themselves in an undefined state. They might have
to fix their mysql data manually. Same thing for users who launched Palm
from scratch; although, according to my preliinary tests, they should be
able to downgrade their connection from utf8mb4 to utf8mb3 without
issue.
In addition, we upgrade to mysql 8.1.0. Among many other fixes, this
avoids a server restart after the upgrade:
> An in-place upgrade from MySQL 5.7 to MySQL 8.0, without a server
> restart, could result in unexpected errors when executing queries on
> tables. This fix eliminates the need to restart the server between the
> upgrade and queries. (Bug #35410528)

Close #887.
It was useless to create a *-permissions job for every application.
Instead, we create a single "permissions" service. It can be extended
via the "docker-compose-permissions-command" patch.
Among other changes: ORA2 file uploads were stored in a folder named
"SET-ME-PLEASE (ex. bucket-name)" (sigh). With this change, the folder
should be automatically renamed to "openedxuploads". This issue has been
occuring since June 2019... (sigh²)
Close #707
Users want to be able to override the request `max_size` to upload
larger files. But they will not be able to if the patch is placed after
the `request` directive. So we move the patch statement before the
directive. Also, we wrap the `request_body` directives within `handle`
statements. If not, then different sizes are not managed properly.
To override the max upload size in the cms, add the following to the
"caddyfile-cms" patch:
handle_path /import/* {
request_body {
max_size 500MB
}
}
See discussion:
https://discuss.openedx.org/t/how-to-update-caddyfile-using-tutor-plugin/8944
The LMS and CMS were producing lots of logs similar to:
cms_1 | 2023-01-17 15:30:11,359 INFO 7 [openedx.core.djangoapps.cors_csrf.helpers] [user 7] [ip 31.223.46.44] helpers.py:64 - Origin 'https://studio.demo.openedx.overhang.io' was not in `CORS_ORIGIN_WHITELIST`; full referer was 'https://studio.demo.openedx.overhang.io/learning/course/course-v1:edX+DemoX+Demo_Course/home' and requested host was 'studio.demo.openedx.overhang.io'; CORS_ORIGIN_ALLOW_ALL=False
These warnings are produced by openedx.core.djangoapps.cors_csrf.helpers. I
don't think they indicate any problem, but they pollute the logs. They are
resolved by adding the "http(s)://<lms/cms host>" to CORS_ORIGIN_WHITELIST in
production, so we did just that.
When a user registers, they receive a confirmation email. This email contained
two links to "https://example.com/..." urls. This was caused by the fact that
the default site, indicated by SITE_ID=1, was example.com. We resolve this
issue by setting instead SITE_ID=2, which should point to the site with the LMS
domain name.
This is a potentially breaking change for platforms that have manually set to 1
the id of the LMS site in the database. These platforms should now set
SITE_ID=1 via a plugin.
Alternatives we have considered include modifying the id field of the LMS site
in the database. Unfortunately such a change would have important consequences,
as the site ID is used as a foreign key for other models.
Note that non-https sites still include https links in the registration emails.
This is because the "https" scheme is hardcoded by the "ensure_url_is_absolute"
utility function. So there is nothing we can do about this without making
changes upstream.
Close #572.
In development, login via the authn mfe was broken because of explicit
enterprise integration:
requests.exceptions.ConnectionError: HTTPConnectionPool(host='localhost', port=18000): Max retries exceeded with url: /enterprise/api/v1/enterprise-learner/?username=regis (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fd4c02b8a90>: Failed to establish a new connection: [Errno 111] Connection refused'))
See: https://discuss.overhang.io/t/tutor-login-fail-in-new-version/3083
This change builds upon a previously proposed PR:
https://github.com/overhangio/tutor/pull/437
There was another long conversation about this topic here:
https://github.com/overhangio/tutor-forum/pull/10#issuecomment-1314799915
We could have supported the MongoDB auth/replica set/ssl parameters as part of
the MongoDB host URI, but then this URI is not supported in the forum plugin,
which uses an old version of the mongoid client. We were hoping that the client
would have been upgraded by now, but it's not been upgraded for a long time.
The changes introduced here are 100% backward-compatible. The forum plugin will
have to be updated to take into account the new parameters.
The ENABLE_CORS_HEADERS feature flag is already true for the LMS.
Instead of duplicating it for Studio via yaml settings, make this a
common Django setting to both LMS and CMS and all their environments.
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).
Compressing assests would lead to readuce transfer size.
As testing with frontend-app-learning/Olive, the network traffic
before was about ~4MB, after this it became ~1MB.
This change was suggested by Google Lighthouse[1], there are of
course more suggestion but this was one the easiest and one of most
impactful.

info.

The pymongo dependency for edx-platform was updated (3.10.1 to 3.12.3)
in https://github.com/openedx/edx-platform/pull/30569
This caused the following error when running the edx-platform database
migration split_modulestore_django.0002_data_migration as part of
`tutor dev quickstart`:
pymongo.errors.ServerSelectionTimeoutError: client is configured to
connect to a replica set named '' but this node belongs to a set named
'None', Timeout: 30s, Topology Description: <TopologyDescription id:
62bdbaf182687350acf1aeec, topology_type: Single, servers:
[<ServerDescription ('mongodb', 27017) server_type: Unknown, rtt:
None, error=ConfigurationError("client is configured to connect to a
replica set named '' but this node belongs to a set named 'None'")>]>
This commit explicitly sets replicaSet to None to indicate that it's a
standalone MongoDB instance. I also had to remove the CONTENTSTORE entry
from auth.yml because edx-platform's devstack.py assumes it has a
non-null value (set in common.py), and devstack.py executes before
tutor's development.py can set this replicaSet value.
Incorrect format of cms.yml config file was causing the following error on course import:

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 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).

- 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.

When nginx was removed in favour of caddy, we decided that plugin
implementations of the "caddyfile" patch should make use of the "port" local
variable. However, local variables are not available from inside plugin
patches, which are rendered outside of the context of the parent templates.
For a more extensive description of the problem, see:
https://github.com/overhangio/tutor-mfe/pull/23#issuecomment-964016190
We still want to make it easy for developers to decide what should the port be
for caddy hosts. To do so, we make use of environment variables that are passed
at runtime to the caddy container.
Thus, a regular plugin patch should look like this:
{{ PLUGIN_HOST }}{$default_site_port} {
import proxy "myplugin:8000"
}
Forum is an optional feature, and as such it deserves its own plugin. Starting

passed to the registration email renderer. That was caused by the
LazyStaticAbsoluteUrl object created to address missing logo in registration
email. To make sure that this object is serializable by
edx_ace.serialization.MessageEncoder, we add a trivial .to_json() method to the
LazyStaticAbsoluteUrl class.
This error could (at first) not be reproduced in development, because
AUTOMATIC_AUTH_FOR_TESTING is set to true in devstack settings.
It should be unnecessary to build a custom openedx-dev Docker image. All tests
can run from within the dev Docker image, with a couple additional environment
variables.
Previously, the logo included in emails was loaded from edX' CDN. Here, we make
sure that the logo is actually the same as the site logo. Because the logo may
be theme-specific, we need to compute the logo url at runtime, and use a
lazily-evaluated string.
Close #447.
As described in issue #284, tutor does not come with codejail enabled out of
the box. Actually, we don't even have a working plugin, yet. To prevent users
from running unsafe code, we explicitely disable python-evaluated input by
disabling the "python" interpreter. This might break some courses; thus, this
is a non-backward compatible change.
