Doctrine Migrations Version Comparator Laravel Package

Getting Started

This package provides a comparator for Doctrine Migrations versions — the piece you need when you want to answer "is migration A before or after migration B?" programmatically instead of eyeballing timestamps in a directory listing.

Minimal steps:

1. composer require softspring/doctrine-migrations-version-comparator
2. If you are not using package auto-discovery, register the service provider in config/app.php.
3. Read src/ before the README — the surface area is small. Identify the comparator class (the thing implementing the version comparison) and any Doctrine config wiring/binding it ships with. That class is where 90% of your integration work will happen.
4. Try it interactively with php artisan tinker against two known migration class names from your database/migrations (or doctrine_migrations) directory. Confirm the ordering it returns matches the ordering Doctrine itself uses when running migrate.

First real use case: a deploy guard. Before running doctrine:migrations:migrate, compare the highest version already recorded in the doctrine_migration_versions table against the highest version present on disk to decide whether there is anything to do, or to gate a post-deploy step (cache warm, backfill, feature flag flip) on a specific migration having been passed.

Implementation Patterns

Comparator as a collaborator, not a string helper. Inject the comparator into your own application service rather than calling version_compare() inline. You then have one place to swap behaviour if your team moves between timestamped (Version20240512103000) and semantic version naming.

Deploy/CI gate. A small artisan command that returns a non-zero exit code when the shipped code contains migrations newer than the last applied version is the highest-leverage pattern. Wire it into your pipeline before the migrate step so a partially-deployed release fails loudly instead of silently running half a migration set.

Version-aware data migrations. Inside a data migration or seeder, compare the current migration version to a threshold and no-op if the threshold has not been crossed. This makes the migration safe to re-run in environments that were restored from a snapshot.

Ordering assertions in tests. In a feature test, assert that a specific migration sorts after a known baseline. That catches accidental renames and hand-edited version strings before they reach a shared environment, where Doctrine will happily skip or re-order them.

Binding the interface. If the package exposes an interface, bind it in a service provider and resolve it from the container everywhere. Keep the Doctrine-specific implementation out of your domain code — this is a build/deploy concern, not a business concern.

Pair with the Doctrine migrations configuration. Read the versions from the same source Doctrine reads them (doctrine_migrations table name, configured migration paths, configured namespace). If your comparator input comes from a stale cache or a different path than Doctrine's, the comparison is meaningless.

Gotchas and Tips

• v5.6.0 ships no changelog body. The release notes only link to a GitHub compare URL (v5.5.10...v5.6.0) with no migration guide, breaking-change callout, or feature summary. Read that diff before bumping: check the composer.json constraint changes, any renamed classes, and any change to how versions are compared. Treat 5.6.0 as unverified until you have run your own version-ordering assertion tests against it.
• Lexical ordering is not semantic ordering. Timestamp versions compare cleanly as strings; semantic versions (1.10.0 vs 1.9.0) do not. Confirm which convention the comparator applies to your format, and do not rely on it for versions from mixed naming schemes — Doctrine itself orders by namespace and name, not by "release significance".
• Cross-namespace comparisons are the classic footgun. Migrations from different namespaces/bundles do not necessarily share a monotonic ordering. If your gate compares across namespaces, you can get a truthful-but-useless answer.
• Table and path drift. Custom doctrine_migrations table names and non-default migration paths are the most common reason a comparator "returns the wrong thing". Verify what the comparator reads versus what Doctrine has configured.
• Config caching. If you add config for this, remember php artisan config:clear locally and that production config caches will not pick up a new key until a fresh deploy.
• Doctrine Migrations major-version API drift. Upgrading doctrine/migrations can change how Version objects are constructed and compared. Pin a compatible range in composer.json and let a test cover the comparison rather than discovering the drift in production.
• Debug with real data. Dump the actual strings being compared (dd($a, $b)) rather than the objects — most "it says A is before B" surprises are whitespace, case, or a truncated version string.
