From 3ed85813325329b71751e494f3fc9903946cea5e Mon Sep 17 00:00:00 2001 From: JJ Fullmer <7743340+darksidemilk@users.noreply.github.com> Date: Wed, 19 Aug 2026 11:52:34 -0600 Subject: [PATCH] Execute the schema, rather than only reading it tests/schema-portable-collation.test.php checks the two schema files textually and rejects a collation outside a portable allowlist. That catches the shape of GH-1147, but only the shape: it cannot catch a statement that is well-formed, names nothing unusual and still will not run on MariaDB 10.5, and it cannot see what the schema RESOLVES to once a server has applied its own defaults, which is the whole of GH-1152. It is textual by design, and its docblock says why -- commons/schema.php "calls self::$DB->query() at file scope and cannot be included without a database". So this test supplies the database. TWO SCRATCH DATABASES, BECAUSE THERE ARE TWO ROUTES The steps in commons/schema.php reach a server one way and the manifest's `create` strings reach it another, so they get one database each. The first replays the indexed steps in order, which is the fresh-install path: SchemaUpdaterPage::update() slices the step array from self::$mySchema, and that is 0 on a new database, so a fresh install really does execute every step from the beginning. The second runs commons/schema-expected.php's `create` strings into an EMPTY database -- the reconciler path. An empty one specifically: run against the first, every table already exists and CREATE TABLE IF NOT EXISTS may short-circuit without the server ever resolving the collation names, which would leave the GH-1147 guard looking like it passed when nothing was checked. Each is then asserted twice: every statement executed (GH-1147), and every resulting table shares one collation (GH-1152). HOW schema.php IS LOADED WITHOUT THE APPLICATION It is include'd from inside SchemaUpdaterPage::update() and expects that method's context -- $this->schema[], self::$DB, self::getClass(). It carries no `namespace`, since the real classes reach it through class_alias into the global namespace, so global stubs are what it resolves against. Two of its dependencies are discovered rather than listed, so that adding either to schema.php cannot quietly break this test. Constants are found by tokenising the file and given placeholders; they only ever reach INSERT statements seeding default settings, and only DDL is executed, so the values do not matter -- DATABASE_NAME and FOG_SCHEMA are set for real because they do. Unknown classes are manufactured by an autoloader whose every call answers null, which is what an empty database looks like to the introspection schema.php performs while building its array. Empty is the correct answer there: a fresh install is exactly the state being modelled, and DatabaseManager::getColumns() returning nothing is why the conditional ALTERs are included, same as on a real one. Measured on this branch, the collection yields 340 indexed steps, 658 string statements, 278 of them DDL, 74 CREATE TABLE, and 9 closures. WHAT IT DOES NOT COVER The closure steps are not executed. They are data migrations that need the full application and emit no DDL. Stated in the docblock rather than left to be discovered: this covers the schema's structure, not its data. Without FOG_TEST_DSN it prints SKIP and exits 0, so `sh tests/run-all.sh` on a machine with no database still reports a green suite -- the convention secureboot-authvars.test.sh already uses for absent efitools. With a DSN set but pdo_mysql missing it FAILS instead, deliberately: a DSN was provided, so skipping would report a pass for a check that never ran. The runner picks it up through its existing *.test.php glob; nothing to register. ALSO, THE JOB NAME .github/workflows/tests.yml declared a bare `suite:`, and the job key is what GitHub puts in the middle of a called workflow's check name, so every check read "Tests / suite / tests (PHP 7.4)". Named `fogproject`, because fog-workflows hosts fog-plugins-tests.yml alongside fogproject-tests.yml and which project's suite is running is the useful thing for that segment to say. This does change the reported check name. Safe because working-1.6 has neither branch protection nor a ruleset requiring status checks -- verified through the API rather than assumed. The workflow itself keeps the name `Tests`.
