Summary

  • Create PlatformHelper utility class with 3 platform-aware SQL expression generators (getYearDiffExpression, getMonthExpression, getYearExpression) using IDBConnection::getDatabaseProvider()
  • Replace all 5 MySQL-specific SQL locations — TIMESTAMPDIFF/CURDATE in QueryService, LIKE on date columns in MemberMapper and LagerMapper — with portable equivalents
  • Declare pgsql and sqlite support in appinfo/info.xml alongside existing mysql
  • Add Docker infrastructure for PostgreSQL (port 8081) and SQLite (port 8082) with corresponding Makefile targets
  • Add CI pipeline (.gitea/workflows/database-portability.yml) with matrix testing across all three backends
  • Add test suites — PlatformHelper unit tests (13 tests) and DatabasePortability integration tests (13 tests), all passing

Security Review

  • PlatformHelper only accepts hardcoded column references (never user input)
  • No SQL injection vectors introduced — column names are string literals at all call sites
  • All existing parameterized queries remain parameterized
  • PHPDoc explicitly documents the security contract

Test Results

  • 210 related tests pass (PlatformHelper + QueryService + Mapper + DatabasePortability)
  • 26 new tests added, all passing
  • No regressions in existing test suite (29 pre-existing errors in FileLinkServiceTest are unrelated)

Closes #192

Replace 5 MySQL-specific SQL expressions with platform-aware equivalents
via a new PlatformHelper utility class that generates correct SQL for
MySQL, PostgreSQL, and SQLite using IDBConnection::getDatabaseProvider().

Core changes:
- Create lib/Db/PlatformHelper.php with getYearDiffExpression(),
  getMonthExpression(), and getYearExpression() methods
- Update QueryService.php to use PlatformHelper for age/duration filters
- Update MemberMapper.php to use month extraction instead of LIKE on dates
- Update LagerMapper.php to use year extraction instead of LIKE on dates
- Declare pgsql and sqlite support in appinfo/info.xml

Infrastructure:
- Add Docker Compose files for PostgreSQL and SQLite variants
- Add Makefile targets: deploy-postgres, deploy-sqlite, etc.
- Add Gitea Actions CI pipeline with matrix testing
- Add PlatformHelper unit tests and DatabasePortability test suite
