Bumping the `OPENEDX_COMMON_VERSION` in the master branch usually
creates a conflict when we merge the change in the nightly branch. To
avoid this conflict, we add some logic to the `OPENEDX_COMMON_VERSION`.
This change should be invisible for most users.
This partially addresses issue #936.
MySQL 8 defaults to a binlog expiry period of 2592000 seconds
(30 days), which for Tutor/Open edX purposes can be considered
excessive.
On the one hand, it is unlikely that a MySQL server configured for
Tutor uses MySQL replication at all (considering that up until Tutor
15 and MySQL 5.7, the binlog was disabled by default, rendering
replication impossible). Even if it does, a replica lagging more than
two days behind the primary server would be unacceptable.
Likewise, it is unlikely that an Open edX database is backed up less
than once a day, thus is is unlikely that Open edX admins would
benefit from the ability to do point-in-time restore over a 30-day
period.
On the other hand, having a 30-day binlog expiry period can
considerably increase the storage space requirements for the MySQL
container, particularly on busy Open edX platforms. When left
unchecked, this can even cause the MySQL container to run into "No
space left on device" situations, disabling the MySQL database
altogether. Thus, the MySQL default settings are likely to be a net
disadvantage for Open edX admins.
Finally, all of the above considerations apply only if the Open edX
administrator has chosen to run their own MySQL and not opted for a
DBaaS solution like AWS RDS.
Thus, it should be acceptable to run with a reduced binlog expiry
period of 3 days (rather than 30) by default.
Therefore, inject the --binlog-expire-logs-seconds=259200 argument
into the Tutor-generated command to start mysqld.

On macOS, building the "openedx-dev" Docker image resulted in an image that required more than 600 GB of disk space. This was due to the `adduser` command which was called with a user ID of 2x10⁹ (on macOS only). This resulted in a very large /var/log/faillog file, hence the image size.

On Oct. 10, py2neo package was abruptly removed from pypi, GitHub, and
the py2neo website now displays just a super funny meme: https://py2neo.org/
Yes, we should get rid of that dependency, but we are still supposed to
support existing users. So we install py2neo from our fork.
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.
Pound keys were interpreted as comments. This is annoying when we want
to parse html color codes, such as in:
$ tutor config save --set "INDIGO_PRIMARY_COLOR=#225522"
$ tutor config printvalue INDIGO_PRIMARY_COLOR
null
Close #866.
This is a follow-up fix to #819, where the corresponding change was
added to the mysqld invocation in the "tutor local" (that is,
docker-compose) deployment method, but omitted from its "tutor k8s"
equivalent.
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)

`tutor ... do settheme default` is meant to revert to the
default theme. However, in its current implementation, it
creates SiteTheme objects pointing to a theme named "default",
which doesn't exist, resulting in errors like:
Theme dirs:
[Path('/openedx/themes')]]
Traceback (most recent call last):
File "/openedx/edx-platform/openedx/core/djangoapps/theming/helpers.py", line 204, in get_current_theme
themes_base_dir=get_theme_base_dir(site_theme.theme_dir_name),
File "/openedx/edx-platform/openedx/core/djangoapps/theming/helpers.py", line 242, in get_theme_base_dir
raise ValueError(
ValueError: Theme 'default' not found in any of the following themes dirs,
This works from the perspective of the user, because a missing theme is
treated as the default theme. However, the errors are unneccesary &
confusing.
By simply deleting & not recreating SiteTheme objects instead,
we are able to revert to the default theme while keeping the
logs clear of theming errors.
Manual configuration via the `MOUNTS` setting was inconvenient. We
(re)introduce a new(ish) `tutor mounts` command. Old timers will perhaps
remember that we used to have a `tutor bindmount` command. Well, it's
back! But better and different.
