This repo is intended to make it easy to contribute to the Drupal core and contrib projects.
Setting up, testing, and writing Drupal patches can be a confusing gauntlet to the uninitiated, lando/drupal-contributions this project automates as much of the process as possible.
The spin ups should be considered completely ephemeral as on every lando rebuild events will be fired to tear down the current code base and rewrite the database with a fresh install.
Using this repo gives you a .lando.yml file configured for Drupal contributions:
- Automatically grabs the Drupal source code and runs
composer installonlando rebuild -y - Automatically kills the source code and database on
lando rebuild -yso you can start fresh with each patch - Adds a
lando phpunitcommand to invoke PHPUnit tests - Adds a
lando sicommand to reinstall the site with fresh DB if you need one (without rebuilding) - Adds a
lando patch URLcommand to pull down and apply a patch from drupal.org - Adds a
lando revert PATCH_NAMEcommand should you need/want to revert a patch - Adds a
lando core-checkcoommand to check code standards and spelling - Adds a
lando create-patchcoommand to create a patch from the current branch

Let's step through how to spin up your contribution workflow. First clone down this repo:
git clone git@github.com:lando/drupal-contributions.git
cd drupal-contributions
This gets us the .lando.yml config and scripts to glue all the processes together.
Next rebuild the drupal-contributions app:
NOTE: Please note that we are using
rebuildand not thestartcommand. Rebuild has the events to trigger getting the Drupal source code and installation.
lando rebuild -y
This will pull in the drupal source code from the latest 9.x-dev branch, run composer install to get dependencies, install Drupal, and provide us with a one time login link (uli). You can update the version in the /config/drupal-branch.php file.
After rebuild completes you should see something similar to this:
___ __ __ __ __ ______
/ _ )___ ___ __ _ ___ / / ___ _/ /_____ _/ /__ _/ /_____ _/ / / /
/ _ / _ \/ _ \/ ' \(_-</ _ \/ _ `/ '_/ _ `/ / _ `/ '_/ _ `/_/_/_/
/____/\___/\___/_/_/_/___/_//_/\_,_/_/\_\\_,_/_/\_,_/_/\_\\_,_(_|_|_)
Your app has started up correctly.
Here are some vitals:
NAME drupal-contributions
LOCATION /home/gff/code/drupal-ops/drupal-contributions
SERVICES appserver, database
APPSERVER URLS https://localhost:33147
http://localhost:33148
http://drupal-contributions.lndo.site/
https://drupal-contributions.lndo.site/
and the web directory should be populated with the Drupal source code.
Now we are ready to find a Drupal core issue. Search the issue queue for a core 9.x issue that you want to test. Grab the URL of the latest patch and apply it to our drupal-contributions environment.
For example if you choose this issue: https://www.drupal.org/project/drupal/issues/3186076, the latest corresponding patch (as of 20 January 2021) is https://git.drupalcode.org/project/drupal/-/merge_requests/161.diff ("plain diff" link). To apply this patch:
lando patch https://git.drupalcode.org/project/drupal/-/merge_requests/161.diff
Note: Both Gitlab-patches with .diff suffix as well as the old style .patch files will work.
To revert the patch:
lando revert 161.diff
This way we can apply and revert as many times as we want/need to during our testing.
To test this issue, apply the patch as outlined above, clear caches, and visit for example /admin/structure/views/view/frontpage, and see that the "Tour" link has been turned blue, and the text extended to "Take a tour of this page".
The patch works!
We can now leave a comment on the issue saying that we tested the patch and it works as expected for us
At the moment, Lando + Drupal Contributions doesn't automate contrib module patch testing and creating. In the meantime, you can still use the drupal-contributions environment to test and create contrib module patches as you would otherwise. One simple method is to search the contrib module issue queue for an issue that you want to test. Grab the URL of the latest patch, and apply it the contrib module in our drupal-contributions environment.
For example, if you choose the geofield contrib module and this issue: https://www.drupal.org/project/geofield/issues/2770313, the latest corresponding patch (as of 2 June 2019) is https://www.drupal.org/files/issues/2019-06-02/geofield-add-GeometryType-storaging-2770313-26.patch. To apply this patch:
cd web/modules;
git clone https://git.drupalcode.org/project/geofield.git;
cd geofield;
wget https://www.drupal.org/files/issues/2019-06-02/geofield-add-GeometryType-storaging-2770313-26.patch;
git apply -v geofield-add-GeometryType-storaging-2770313-26.patch;
Note: Both Gitlab-patches with .diff suffix as well as the old style .patch files will work.
If the patch fails, try to figure out why. For example, run its phpunit tests:
lando phpunit --group geofield;
If you discover anything useful, leave a comment on the issue at drupal.org.
To revert the patch:
lando revert geofield-add-GeometryType-storaging-2770313-26.patch
This way we can apply and revert as many times as we want/need to during our testing.
If you are fixing a drupal.org core issue, you should enter the web folder, checkout a branch using the prescribed naming conventions ISSUE####-COMMENT#. Write your code. Commit your code. Check your code using lando core-check. Then you can utilize the lando create-patch to output the patch file based on your branch name.
lando core-check
This will run the same tests that the testbot runs before running the actual PHPUnit tests: spell check, CodeSniffer, etc. You can ignore reports that your files have permissions 664 instead of 644.
lando create-patch
This will output a patch file to /app/ISSUE####-COMMENT#.patch, which you can upload to the drupal.org issue.
For example, these are the steps required to create a core patch. This example creates a branch, updates the CHANGELOG.txt core file, commits the update and creates the patch.
cd web
git checkout -b 987654-new-patch
echo "TEST" >> core/CHANGELOG.txt
git add core/CHANGELOG.txt
git commit -m "Updates CHANGELOG.txt"
lando core-check
lando create-patch
To create a contrib module patch, for example Admin Toolbar, download it to the modules folder, following the instructions under Version control:
cd web/modules
git clone --branch 8.x-2.x https://git.drupalcode.org/project/admin_toolbar.git
Inside the contrib module folder, create a branch in the format ISSUE####-COMMENT#. For example:
cd admin_toolbar
git checkout -b 1234567-admin_toolbar-improved-paths
Make your changes.
...(code code code)...
Test your changes. For example:
cd ../drupal-contributions;
lando phpunit --group admin_toolbar;
// or run a single test
lando phpunit web/modules/admin_toolbar/tests/src/Functional/AdminToolbarAlterTest.php
When you are ready, add/commit the relevant changes and create the patch. For example:
git add this.php that.js
git commit -m "Your commit message"
// While still on your patch branch, git diff the module's dev branch and redirect its output to a file in the format ISSUE####-COMMENT#.patch. For example:
git diff 8.x-2.x > 1234567-admin_toolbar-improved-paths.patch
Verify your own contrib module patch against the module's dev branch. For example:
git checkout 8.x-2.x;
git apply -v 1234567-admin_toolbar-improved-paths.patch;
// Verify output of above command is:
Checking patch...
Applied patch...cleanly.
If the patch works, upload it to the drupal.org contrib module issue.
PHPUnit runs all the tests in Drupal 8 and above, to run tests with PHPUnit:
List all tests groups:
lando phpunit --list-groups
Run one group of tests, for example BigPipe:
lando phpunit --group big_pipe
Run multiple groups of tests:
lando phpunit --group Group1,Group2
Exclude a group of tests:
lando phpunit --exclude-group Groupname
Run a single test, the Drupal core password hashing API:
lando phpunit web/core/tests/Drupal/Tests/Core/Password/PasswordHashingTest.php
To run only core tests, run:
lando nightwatch --tag core
To skip running core tests, run:
lando nightwatch --skiptags core
To run a single test, run e.g:
lando nightwatch tests/Drupal/Nightwatch/Tests/exampleTest.js
Once you have the latest 9.x-dev branch you can keep it and sync it periodically and lando start's will keep that around. If you want to totally start fresh:
# destroys drupal-contributions app and removes /web
lando destroy -y
# Spin up a fresh checkout of Drupal source installed and ready
# for dev, patching, and testing.
lando rebuild -y
