This version of Drupal 11.x (11.3.x) is broken.
Although Drupal 11.3.x is supposed to work with PHP 8.1+, it's not working here with PHP 8.3.23 We can see that if we ddev launch /core/install.php we'll get an error.
Use git bisect to find out when PHP 8.3.23 stopped working.
- Check out the repo,
git clone https://github.com/rfay/git-bisect-example ddev config --php-version=8.3(Gets current default DDEV PHP, 8.3.23 as of 7/2024)ddev composer installddev launchwill fail withYour PHP installation is too oldddev config --php-version=8.4andddev restartand try again. It works.- Set it back with
ddev config --php-version=8.3andddev restart.
You know that Drupal 11.2.0 installed fine with any PHP 8.3, but it doesn't with the current version here.
Use git bisect to find out what went wrong.
git bisect start
git bisect bad # We know it's bad right here
git checkout 11.2.0
ddev launch # Should work
git bisect good # so we mark it goodContinue with git bisect good or git bisect bad using ddev launch to check whether the install will work, until it finds the bad commit.
You can go a step farther and automate the check. For example,
curl -s https://git-bisect-example.ddev.site/core/install.php | grep -q "<title>Choose language" >/dev/null
will return bash "carview.php?tsp=true" or 0 when it's working, so can be used instead of manually hitting ddev launch and verifying it.
So with this script in ~/tmp/check-installable.sh and the script set to executable, you can find the answer much more quickly. (The script can't be in the repository because we're checking over various checkouts of various revisions of the repository.)
#!/bin/bash
sleep 1
ddev mutagen sync >/dev/null 2>&1 # make sure the git checkout has propagated if mutagen enabled
echo "Result of ddev mutagen sync: $?"
sleep 1
ddev composer install --no-interaction >/dev/null 2>&1
echo "Result of composer install: $?"
curl -sfL https://git-bisect-example.ddev.site/core/install.php | grep "<title>Choose language" >/dev/null
rv=$?
#sleep 1
echo "Result of curl-grep is $rv"
exit $rvgit bisect reset
git bisect start 11.x 11.2.0 # git bisect <bad> <good>
git bisect run ~/tmp/check-installable.shCaveats:
- At each point in the bisect, git has checked out fresh code. You may need to take action to make that code completely usable. As a demonstration this script does a
ddev composer installfor example, so thevendordir and related files are up-to-date related to the code being executed. - In some situations you might have to load a fresh database at each point, or a
drush si, or take whatever action is required to set the site to the initial state you're interested in. We don't have to do that in this example becauseinstall.phpis not dependent on a lot of things. - On macOS and Windows, Mutagen is enabled in DDEV by default, and we are making massive changes with each git checkout that
git bisectdoes. It can take mutagen a moment to sync all those changes. As a result, the script adds addev mutagen syncto ensure that the sync is complete before we execute our test.
