Description

doctrine-retry-bundle was pinned to doctrine/doctrine-bundle ^2.1 and Symfony ^7.0|^6.4, which prevents consumers (the editor service) from moving to Symfony 8 — doctrine-bundle 2.x is incompatible with symfony/var-exporter 8.x. This bumps the bundle's dependency stack so it installs cleanly on Symfony 8:

• doctrine/doctrine-bundle → ^3.0, Symfony components → ^8.0|^7.4.
• Dev tooling: PHPUnit → ^13.0, keboola/coding-standard → ^16.0, added phpstan-doctrine and phpstan-symfony extensions.
• PHPUnit and PHPStan config updated for the new major versions (phpunit.xml.dist schema 13.0 / <source> element, phpstan.neon → phpstan.neon.dist); Rector/coding-standard pass applied to src/tests.
• Tests now load env via symfony/dotenv (optional .env.local) and validate the required TEST_DATABASE_* / TEST_PROXY_HOST variables in bootstrap.php; README documents the Toxiproxy-backed setup and the docker compose run one-liner.

No runtime behavior change — the retry driver logic is unchanged aside from a type-hint added for static analysis.

Justification

See the linked Linear issue: unblocks the Symfony 8 / Doctrine upgrade of the editor service.

Plans for Customer Communication

None.

Impact Analysis

Library-only change; affects consumers that depend on keboola/doctrine-retry-bundle. The minimum supported Symfony/doctrine-bundle versions move up (Symfony 7.4+, doctrine-bundle 3.x), so consumers still on Symfony 6.4 / doctrine-bundle 2.x cannot take the new release — this is intentional. No feature flag.

Deployment Plan

Release a tagged version.

Rollback Plan

Post-Release Support Plan

None.

Verdict: needs_human (risk 3/5) · profile ajda

This PR intentionally raises minimum supported versions in a platform-libraries shared library, making it a backward-incompatible change that needs human review.

Concerns:

• libs/doctrine-retry-bundle/composer.json: Production require bumped by a major version (doctrine-bundle 2→3, Symfony 7→8); major bumps are not auto-safe per policy.
• libs/doctrine-retry-bundle/composer.json: Intentional BC break for consumers on Symfony <7.4 / doctrine-bundle 2.x; platform-libraries BC breaks require human review.
