Here, we upgrade the Open edX platform from Ironwood to Juniper. This
upgrade does not come with many feature changes, but there are many
technical improvements under the hood:
- Upgrade from Python 2.7 to 3.5
- Upgrade from Mongodb v3.2 to v3.6
- Upgrade Ruby to 2.5.7
We took the opportunity to completely rething the way locally running
platforms should be accessed for testing purposes. It is no longer
possible to access a running platform from http://localhost and
http://studio.localhost. Instead, users should access
http://local.overhang.io and https://studio.local.overhang.io. This
drastically simplifies internal communication between Docker containers.
To upgrade, users should simply run:
tutor local quickstart
For Kubernetes platform, the upgrade process is outlined when running:
tutor k8s upgrade --from=ironwood
When running "python setup.py install" in CI, we were getting
"requests distribution was not found and is required by kubernetes"
errors. I can reproduce this issue locally. The error disappears after
the same command is run a second time.
This is a similar issue: https://github.com/pypa/setuptools/issues/498
The github-release is no longer maintained by aktau. We need to upgrade
because of Github authentication warnings. We also add a custom python
script for uploading assets to github. We thought it would be a simple
script, but instead we need to deal with deletion of existing assets and
releases, so we decide instead to keep relying on that 3rd-party script.
This is for supporting json-based plugins. The great thing about this
change is that it allows us to easily print plugin version numbers in
`plugins list`.
We are facing the following issues in CI:
$ ./dist/tutor --version
[5201] Failed to execute script pyi_rth_pkgres
Traceback (most recent call last):

Otherwise, tutor-openedx will be pulled from pypi during plugin install.
This was failing because the latest pypi release was not installing
correctly (see #261).
All existing plugins are added to the binary bundle, in their latest
version, so that users don't need to pip install tutor.
Also, the tutor MANIFEST.in file was removed to simplify the management
of package data.
Close #242.
Thus, we remove the -y/--yes options, which were kind of unintuitive,
and we add instead `-i/--interactive`. The quickstart commands remain
interactive by default, but can be silenced with `-I/--non-interactive`.
The "latest" tag is a pain to maintain: it's a tag that we delete and
re-create at every release. Whenever we delete it, the binaries become
unavailable on Github until they are re-generated. Thus, from now on, we
conform to good practices (as examplified by the
github.com/docker/compose) project and distribute only pinned release.
The "nightly" tag remains, for now, as it allows us to distribute beta
features. It may disappear in the future.
For some reason, the "nosetests" binary is not available on Mac OS in
Travis-ci. This is what we get when we try to install nose:
Requirement already satisfied: nose==1.3.7 in
/usr/local/Cellar/numpy/1.14.5/libexec/nose/lib/python3.6/site-packages
(from -r requirements/dev.txt (line 25)) (1.3.7)
Environment is no longer generated separately for each target, but only
once the configuration is saved.
Note that the environment is automatically updated during
re-configuration, based on a "version" file stored in the environment.
