CI failures on MySQL/MariaDB since recent dependency updates

[dereuromark]

Description

Recent CI runs on PRs against 5.x branch are failing on MySQL and MariaDB tests, even though the 5.x branch itself was green as of Feb 25. These appear to be pre-existing issues unrelated to PR changes.

Failures

1. MariaDB: testMigrateAndRollback assertion failure

Failed asserting that two strings are equal.
--- Expected
+++ Actual
@@ @@
-'current_timestamp()'
+'CURRENT_TIMESTAMP'

/home/runner/work/migrations/migrations/tests/TestCase/MigrationsTest.php:228

The test at line 223-224 expects current_timestamp() (lowercase with parentheses) for MariaDB:

if ($driver instanceof Mysql && $driver->isMariadb()) {
    $expected = 'current_timestamp()';
}

But it's receiving CURRENT_TIMESTAMP (uppercase, no parentheses), suggesting either:

• isMariadb() is returning false (using MySQL default)
• MariaDB 11.8 changed to return the uppercase format

2. PHP 8.5: BakeMigrationDiffCommandTest errors

Error: Typed property Cake\Database\Schema\Column::$fixed must not be accessed before initialization

/vendor/cakephp/cakephp/src/Database/Schema/Column.php:530

This was reported in cakephp/cakephp#19308 and was related to cached table schema. It may be a cache clearing issue in the test environment.

Environment

• CI uses mariadb:11.8 Docker image
• PHP versions: 8.2, 8.3, 8.5
• CakePHP constraint: ^5.3.0 (currently resolves to 5.3.2)

Related

• PR Fix ci for mariadb #1024 fixed similar MariaDB collation issues but not this timestamp issue
• CakePHP issue #19308 about Column::$fixed initialization

Confirmed: 5.x branch is now failing

I triggered a manual CI run on the 5.x branch and it's now failing with the same errors:

Run: https://github.com/cakephp/migrations/actions/runs/22544260147

Failing jobs:

• ❌ testsuite-linux (8.2, mysql)
• ❌ testsuite-linux (8.3, mysql)
• ❌ testsuite-linux (8.5, mysql)
• ❌ testsuite-linux (8.3, mysql, false)
• ❌ testsuite-linux (8.2, mariadb)
• ❌ testsuite-linux (8.5, mariadb)

Passing jobs:

• ✅ All PostgreSQL tests
• ✅ All SQLite tests
• ✅ cs-stan (code style/static analysis)

This suggests a dependency update (likely CakePHP core) between Feb 25 and now introduced a breaking change that affects MySQL/MariaDB schema handling.
