The suite ran on in-memory SQLite, an engine production never uses: it hid
column lengths, MySQL-only syntax and type coercion (the identity bug fixed in
the previous commit passed CI that way). SQLite is gone:
- TestDb connects only to MariaDB/MySQL (XCVM_TEST_DB_DSN/_USER/_PASS; root over
the local socket, else 127.0.0.1:3306). Each instance gets a throwaway
schema, dropped with it, in the installer's sql_mode, with an explicit
connect timeout (a boot under test can zero default_socket_timeout).
- InstallSchema and the tests take the production DDL as is: the SQLite
reducers, the keys they re-added, the faked information_schema and the
sqliteCreateFunction() stand-ins are removed; test DDL is MySQL DDL.
- ReplicaBootTest, DbConnectRefusalTest and LazyDatabaseHandlerTest reach the
test server instead of SQLite files; RecordingFinalizer no longer swallows
an information_schema failure "for tests on SQLite".
- `make test-db` starts a throwaway mariadb:11.4 (tmpfs) for a machine without
a server; the CI PHPUnit job gets the same as a service.
The suite also runs on a panel host with the bundled PHP and its own php.ini:
tests reach the code through MAIN_HOME, not `<repo>/src`; repository checks
and process-isolated tests (ionCube Loader + OPcache CLI segfault on a script
read from stdin) are in the skip-on-panel group; xcvm_test_child_php() starts
a child that fakes \XC_VM without the real extension; Redis-down tests use
RedisManager::useConnector() instead of an eval'd \XC_VM.
Stale opt-in tests fixed on the way: the real-agent provisioning test answers
the agent-started check, the extension integration test sends the typed starts
and reads the binary signature raw, a fake producer starts as PHP_BINARY, and
the certbot test waits for the line its background command writes.
Three Phase 0 seams, each with the current database behaviour as its only
backend:
- StreamSource: the stream row, this node's streams_servers row and the
stream options a node reads before running a stream. The launcher
(live, VOD and LLOD starts), MonitorCommand, ProxyCommand, ScannerCommand
and live.php's fanout proxy hand-off ran these queries themselves.
- StreamRowMerge: MAIN's side of a node's runtime state. StreamStateWriter's
SQL backend now calls it; later it merges `stream.state` events keyed by
the reporting node. eventFields() keeps only runtime columns and redacts
the source URL.
- StreamCacheBuilder: the stream_<id> cache entry (columns, server rows,
the direct-source rule), extracted from cron:cache_engine so the R2
stream delta can build the same shape.
OndemandCommand's stop path also still wrote streams_servers and signals
with raw SQL. It now uses StreamStateWriter and SignalDispatcher, like the
rest.
