…thods (7.0)
Version 7.0 completes the refactoring started in 6.0 and adds the
observability features:
Breaking changes:
- Remove the query methods deprecated since 6.0 (getIterator, getScalar,
getAllFields, execute, executeAndGetId) from DbDriverInterface, the
PDO/OCI8 drivers and DatabaseRouter. DatabaseExecutor is now the
single API for executing queries and commands.
New features:
- Generic event mechanism on DatabaseExecutor
(DatabaseEventObserverInterface, addObserver/removeObserver) firing
BEFORE/AFTER_QUERY and BEFORE/AFTER_EXECUTE events, with no overhead
when no observer is attached.
- Journal package records INSERT, UPDATE and DELETE statements with the
row values before and after each operation:
- JournalRecorder watches all tables or a specific set, with
configurable primary keys
- JournalRestorer replays the journal in reverse to restore the
previous database state (functional test setUp/tearDown)
- Optional strict mode throws JournalException on statements that
cannot be journaled/restored instead of skipping them silently
Infrastructure:
- Pin the SQL Server image to 2022-latest in docker-compose.yml and CI:
the 2025 image (current 'latest') crashes on startup on hybrid CPUs
(Intel P/E-cores) with a topology assert. Rename the compose service
from mssql to sqlserver (matching CI), use MSSQL_SA_PASSWORD instead
of the deprecated SA_PASSWORD, and fix wait-for-db.sh reporting the
database as up when the health check timed out.
Includes tests, documentation (docs/observers.md, docs/journal.md,
removal notes across existing docs) and CHANGELOG-7.0.md.
