feat: add quarkus-morphium extension as optional module

[Bardioc1977]

Hi Stephan,

Glad #266 landed! Here comes the second building block of the modularization: quarkus-morphium, the Quarkus CDI extension for Morphium.

What this PR does

Four submodules (runtime, deployment, testing, integration-tests), three of them published:

• CDI producer for Morphium, type-safe runtime configuration via @ConfigMapping (quarkus.morphium.*)
• @MorphiumTransactional with CDI transaction events (MorphiumTransactionEvent), including automatic detection when Azure CosmosDB doesn't support multi-document transactions
• Liveness/readiness/startup health checks via SmallRye Health
• Dev Services (auto-started MongoDB container, optionally as a single-node replica set)
• Dev UI card with live connection info
• Build-time generated Jakarta Data @Repository implementations via Gizmo bytecode (no runtime reflection, no dynamic proxies)
• GraalVM native-image support (automatic reflection registration for every @Entity/@Embedded class)
• MorphiumId JSON serialization as its canonical 24-character hex string (Jackson + JSON-B)
• MongoDB-backed migration runner with a distributed lock

groupId change

The extension previously published under io.quarkiverse.morphium, but it doesn't actually live in the Quarkiverse organization (no response from the maintainers on a namespace request). Maven coordinates now follow Morphium's own groupId, de.caluga:quarkus-morphium, with lockstep versioning to the reactor. Existing users of io.quarkiverse.morphium:quarkus-morphium:1.2.0 need to change the groupId to de.caluga and the version to the adopted Morphium version (currently 6.3.x) — no package renames, no API changes, only the Maven coordinates move.

Optionality

The core is unchanged (git diff --stat against develop confirms morphium-core, poppydb, morphium-jakarta-data are untouched). The core dependency tree is free of Quarkus/Testcontainers. -DskipExtensions builds only core + PoppyDB + morphium-jakarta-data. The Quarkus BOM import stays in the module POM (quarkus-morphium/pom.xml); only the version property (quarkus.version) lives centrally in the parent, so a Quarkus upgrade is a one-line change — if the BOM import itself moved to the parent, every core build would have to resolve ~400 Quarkus coordinates despite the core having no Quarkus dependency.

Docker and integration tests

integration-tests uses Testcontainers for real MongoDB instances. Without a running Docker daemon, the affected test class skips itself (via a DockerClientFactory.instance().isDockerAvailable() check), keeping the build green. The integration-tests module is not published to Central.

Extension conformance

A 30-point audit against the official Quarkus extension guidelines (naming scheme, build-step registration, deployment-artifact parity, quarkus-extension.yaml completeness) found 21 fully met, 5 partially met, and 3 violated points — all 3 violations were fixed before this PR (see "Community review" below).

Community review before this PR

As with #266, a review PR against my own fork ran first (CodeRabbit skipped it due to file count, GitHub Copilot found four real bugs): a missing build-step registration that would have silently disabled most extension features, a wrong native-image resource path (old groupId), Dev Services still starting a container despite an explicit InMemDriver, and a doc line showing a Jakarta Data 1.1 annotation that doesn't exist yet in the 1.0.0 version used here. All four fixed and covered by regression tests.

Verification

• Extension modules in isolation: 40 tests green
• integration-tests: 242/242 tests green (Docker via Testcontainers)
• Full 9-module reactor: BUILD SUCCESS
• Full core test suite: identical, already-known pre-existing flakes from feat: add morphium-jakarta-data as optional module #266 (messaging timing, Byte Buddy/JDK 25, no local Mongo server) — no regression

What's next

spring-boot-morphium as the third and final building block follows as a separate PR once this one is merged.

Open questions for you

• Should the Antora docs (quarkus-morphium/docs/) be published anywhere, or is the new MkDocs overview page (docs/quarkus-extension.md) enough?
• Extension status: preview or stable?
• Is a Docker requirement for parts of CI acceptable from your side?

Pull request overview

This PR adds quarkus-morphium as a new optional Quarkus CDI extension module within the Morphium reactor, keeping core artifacts extension-free while providing Quarkus integration features (config mapping, Dev Services, health checks, Dev UI, Jakarta Data repository generation, native-image support).

Changes:

• Adds the new multi-submodule quarkus-morphium extension (runtime/deployment/testing + non-published integration-tests) with Quarkus runtime features, build steps, and extensive integration tests.
• Updates the reactor/release tooling to publish the new Quarkus extension artifacts and include the intermediate quarkus-morphium-parent POM in the Central bundle.
• Extends project documentation (MkDocs + Antora) and changelog to describe the new optional module and its usage.

Thanks Copilot! All 4 findings confirmed and fixed:

1. antora.yml: fixed the stray page-toclevels: 3@ typo.
2. health-checks.adoc: corrected the note — quarkus-smallrye-health is deliberately optional, not transitive; added the explicit-dependency instruction.
3. SslConfig.java: fixed the Javadoc example to use the actual quarkus.morphium.ssl.x509-username property key.
4. MorphiumDevUIProcessor: updated the Dev UI card link from the old archived standalone repo to this one.

Also checked for the same bug classes elsewhere in the module (other x509-username references, other repo links) — no further instances found.

There are at least two correctness issues that can cause unintended behavior (Dev Services starting despite atlas-url configuration, and enum-state migration queries that may not match stored values).

• state is stored as the ChangeState enum (see recordExecution(...).setState(state)), but the query compares it to a string (EXECUTED.name()). In Morphium, enum queries are typically performed using the enum constant itself; using the string risks returning 0 executed migrations (and re-running already executed migrations) depending on enum mapping.
  quarkus-morphium/deployment/src/main/java/de/caluga/morphium/quarkus/deployment/MorphiumDevServicesProcessor.java:75
• Dev Services are skipped only when quarkus.morphium.hosts is configured, but Morphium also supports quarkus.morphium.atlas-url as an alternative connection source. If an app sets atlas-url (and leaves hosts unset), this processor will still start a MongoDB container unnecessarily and inject host overrides that the runtime will ignore (since atlasUrl takes precedence).

        if (ConfigUtils.isPropertyNonEmpty("quarkus.morphium.hosts")) {
            log.debug("Morphium connection settings already configured – skipping Dev Services");
            return null;

Thanks for the second pass!

Dev Services + atlas-url: confirmed and fixed. Now also skips Dev Services when quarkus.morphium.atlas-url is set, matching the existing hosts check.

Enum-state migration query: verified, but this one is actually correct as-is — no change made. MorphiumMigrationRunner stores the ChangeState enum on a typed field (private ChangeState state), and Morphium's ObjectMapperImpl.serializeEnum() stores typed enum fields as the plain name() string (only untyped/Object-declared fields get the {class_name, name} wrapper). On the query side, MongoFieldImpl.checkValue() converts any Enum argument passed to .eq() via ((Enum) val).name() before building the filter — so .eq(EXECUTED.name()) and .eq(EXECUTED) produce byte-for-byte identical queries here. Happy to point at the exact lines if useful (ObjectMapperImpl.java serializeEnum(), MongoFieldImpl.java checkValue()).

quarkus-morphium/runtime/src/main/resources-filtered/META-INF/morphium-version.properties:2

• morphium.version is populated from ${morphium.version}, but there is no morphium.version Maven property in the reactor. With resource filtering this will typically end up as the literal string ${morphium.version} in the JAR, so MorphiumVersion.morphiumVersion() will report an incorrect value (and the startup log line in MorphiumProducer will be wrong). Since this module is lockstep-versioned with Morphium core, ${project.version} should be used here (or alternatively define a morphium.version property in the parent).
  quarkus-morphium/runtime/src/main/java/de/caluga/morphium/quarkus/MorphiumRuntimeConfig.java:39
• The example application.properties snippet contains quarkus.morphium.******, which is not a valid property key and reads like a placeholder that was meant to demonstrate setting the password. This makes the docs misleading for users copy/pasting the snippet.

Thanks for the third pass!

morphium.version placeholder: confirmed and fixed. ${morphium.version} referenced a Maven property that doesn't exist anywhere in the reactor — with resource filtering that left the literal placeholder string in the built JAR instead of a real version. Since this module is lockstep-versioned with Morphium core, it now uses ${project.version}, the same expression extension.version in the same file already uses. Added MorphiumVersionTest to catch a regression here.

Example password in MorphiumRuntimeConfig Javadoc: confirmed and fixed. Replaced with the changeit placeholder already used elsewhere in this codebase's SSL/keystore examples, to avoid reading like a real credential.

🟡 Changes recommended

The new Quarkus test modules depend on io.quarkus:quarkus-junit, which is likely the wrong artifactId (should be quarkus-junit5) and can break Maven resolution/builds.

• This test claims to cover an entity without @Version, but it uses ItemEntity, which is versioned. That makes the DisplayName/comments misleading and reduces the value of the test signal.

Hi Heiko,

first of all: impressive work again — clean module split, the Gizmo layer delegating to the shared morphium-jakarta-data bridges is exactly the right design, and the test discipline is well above average. Before this can go in, though, a deep review (Claude did the heavy lifting here, working through all 134 files — the findings below were verified against the actual code) turned up a number of issues that I'd like to see addressed.

This review is based on the current head including your Copilot-round fixes (c23ba60d…10bc8700) — the ${morphium.version} placeholder and the atlas-url Dev Services skip are already resolved and not listed below. One note on Copilot's latest pass: the quarkus-junit finding is a false positive — io.quarkus:quarkus-junit exists on Central and is managed by quarkus-bom 3.32.3 (your green test runs confirm resolution works), so no change needed there.

Quick answers to your questions first:

1. Antora docs: your call — I'd suggest publishing them under the existing gh-pages setup so they're reachable; the MkDocs overview page alone feels a bit thin for an extension this size.
2. Extension status: let's stay with preview for the first release (which is what quarkus-extension.yaml currently says anyway) — given the findings below that's also the honest label. We can promote to stable in a follow-up release.
3. Docker in CI: not a concern for me. I'm personally not a Docker fan, but if it works for you, it works for me — see finding 7 though, the no-Docker fallback currently doesn't do what the PR description claims.

Merge blockers

1. quarkus.morphium.read-preference is silently ignored. MorphiumProducer.java:290 calls driverSettings().setDefaultReadPreferenceType(String) — a dead field in core that nothing consumes. The actual read path uses getDefaultReadPreference(), which defaults to ReadPreference.nearest(). So every app on a replica set reads with NEAREST instead of the documented default primary (stale reads out of the box), and no setting changes that. Fix: cfg.setDefaultReadPreferenceType(...) (which parses + sets) or build a ReadPreference and call setDefaultReadPreference(...).

2. Gizmo generation produces broken classes for legal Jakarta Data signatures (MorphiumDataProcessor.java):

   • Non-void @Delete methods (long removeByStatus(...) — allowed by spec): the method descriptor uses the declared return type but both branches emit returnVoid() → VerifyError at class load, i.e. app startup crash.
   • short/byte/char parameters: boxPrimitive/unboxPrimitive fall through the default branch → VerifyError as well.
   • Abstract methods the processor can't handle are silently skipped → AbstractMethodError on first production call. These should fail the build instead.

3. Silently wrong query results:

   • @Find parameters without @By are dropped entirely — @Find List<Book> byAuthor(String author) returns all books. The @Query path already implements the parameter-name fallback (Jakarta Data §4.6.1, -parameters is enabled); the @Find path omits it.
   • Sort/Order/PageRequest/Limit on derived findBy* methods are ignored (wrong ordering), and Page returns run into a ClassCastException via returnsSingle.

4. Transaction context can leak onto Quarkus worker-pool threads (MorphiumTransactionalInterceptor): catch (Exception) misses Errors, and a failing abort (primary stepdown — getPrimaryConnection throws before the clearTransactionContext() finally) leaves the ThreadLocal context set. The next request on that thread "joins" a dead transaction → silent data loss. Needs catch (Throwable) plus defensive context clearing. (Root cause of the abort case is arguably in morphium-core; happy to take that part there.)

5. Commit retry can double-apply a transaction. A transient error thrown by the commit itself (e.g. code 251 after failover where the server actually committed but the reply was lost) retries the whole business method → all inserts applied twice. Drivers retry only the commit for exactly this reason, never the statements.

6. Migration lock mutual exclusion breaks after the 60s TTL. The lock is never renewed during execution — a migration running longer than the TTL lets a second instance atomically steal the lock and run the same still-running change unit concurrently. A heartbeat extending expires_at (owner-guarded) is needed. Also: a held lock currently fails startup immediately instead of waiting — in a k8s rollout with 3 replicas, two pods crash-loop until the migration finishes. (The lock acquisition itself is genuinely TOCTOU-free — verified down through the writer/wire layers. Nice.)

7. The advertised Docker-skip doesn't work. The assumeTrue(isDockerAvailable()) in MorphiumTransactionalTest sits in @BeforeAll, but QuarkusTestExtension boots the app (and Dev Services start the container — MorphiumDevServicesProcessor.java:103 has no Docker guard at all; compare Quarkus' own DevServicesMongoProcessor, which gates on DockerStatusBuildItem) before user @BeforeAll runs. Without Docker the build goes red instead of skipping. The check belongs in the processor (skip Dev Services with a warning) and/or a JUnit ExecutionCondition.

8. @MorphiumTransactional on async/reactive methods commits too early. For Uni/CompletionStage returns (or the doXxxAsync repository methods, which run on morphium's async pool) the interceptor commits before the actual DB work happens on another thread. Should at least fail fast on async return types.

9. Docs document a property that doesn't exist: quarkus.morphium.create-indexes (in configuration.adoc and README) — the real property is index-check. This also breaks the "all quarkus.morphium.* properties are unchanged" migration promise for 1.2.0 users. The configuration.adoc "documents every available property" claim misses 10 properties (including the whole migration.* group).

Should-fix (can be follow-up issues)

• MorphiumBlockingCallDetector observes StartupEvent and dereferences the Morphium proxy → forced blocking connect (with the full retry ladder) on the boot thread; defeats lazy init and the startup health check. Rolling deploy with Mongo briefly unreachable → CrashLoopBackOff.
• Liveness check is coupled to driver.isConnected() — a Mongo outage makes k8s restart every pod in a loop. DB connectivity belongs in readiness only (which already does it right, citing the Quarkus MongoDB extension precedent itself).
• index-check=create-on-write-new-col leaves core's WARN_ON_STARTUP ClassGraph scan active → native-image crash; the one gap in the otherwise careful index-check matrix.
• Dev Services skip logic is a blacklist (everything except PooledDriver skips) — SingleMongoConnectDriver users lose Dev Services. Should be an InMemDriver whitelist.
• The default Dev Services path (replica-set container) has zero automated coverage — all integration tests run InMem with Dev Services disabled.
• MorphiumStartupCheckTest tests a copy of the formula, not the production class — flipping || to && in MorphiumStartupCheck wouldn't fail any test.
• Partial credentials (username without password) silently connect unauthenticated; malformed MorphiumId in a JSON body yields HTTP 500 instead of 400; (int) cast of cache.global-valid-time can overflow.
• Empty-transaction tolerance depends on the exact server error string "Cannot start a transaction" (untested); BEFORE_COMMIT fires once per retry attempt (duplicate outbox side effects); CosmosDB detection is fail-open with a dead UnsupportedOperationException catch.
• Migration polish: client-clock skew shortens the effective lock TTL; a failing rollback is only logged (not suppressed into the thrown exception, changelog stays FAILED); order compared as plain string ("10" < "2"); the idempotency requirement for change units is undocumented.
• Native image: custom @Entity(nameProvider=...) classes aren't registered for reflection; subclasses of annotated base classes escape the Jandex scan (annotations aren't @Inherited, core resolves via hierarchy walk).
• Docs drift: SNAPSHOT versions hardcoded in antora.yml/attributes.adoc/README (release.sh only touches poms); testing.adoc shows morphium.* without the quarkus. prefix; gaps/JAKARTA-DATA.md is stale.
• pom.xml note: -DskipExtensions also skips morphium-jakarta-data (same profile), so it's "core + PoppyDB only" — the PR text says otherwise.

Verified as correct (so you don't re-check)

Core untouched (zero diff hunks in morphium-core), no Quarkus/Testcontainers in the core tree, BOM placement as described (3.32.3 resolves everything), all 5 @BuildStep classes registered, no io.quarkiverse coordinates left, integration-tests doubly excluded from publishing, release.sh sane (bash -n, module/artifact registries complete), Dev UI leaks no credentials (Atlas URL sanitized), all Gizmo call-site descriptors match the real bridge signatures, driver names match core's @Driver annotations, health checks are cheap per probe, and the STATIC_INIT/RUNTIME_INIT migration ordering via the marker build item is correct.

Happy to discuss any of these — and thanks again, the overall shape of this is very good.

[sboesebeck]

Hi Heiko,

good news first: I've reviewed the A/B fix commits (0b5fab493, 89b40b71c, 55b21f018) — both fixes are correct and well-tested. The mutation-verified commit-retry test and the delete/count tests asserting actual database state are exactly the kind of coverage this needed. 👍

I'd like to get the release out, so here's the deal: you don't need to work through the whole remaining list before merge. Only two items left on the merge path, both one-liners:

1. renewLock() must abort on n == 0. The update result already carries n (same as acquireLock() reads) — when the renewal matches 0 documents the lock was stolen, and continuing to run the remaining change units means two instances migrating concurrently. Throwing there turns the last remaining silent-corruption path into a loud failure. (The full in-flight heartbeat can wait — with this abort in place, the TTL-vs-longest-unit contract from the config Javadoc is an acceptable, documented limitation for preview.)

2. CREATE_ON_WRITE_NEW_COL needs setIndexCheck(NO_CHECK). As per my earlier comment: the branch currently leaves core's default WARN_ON_STARTUP active (CollectionCheckSettings.java:9), and the Morphium constructor then runs the live ClassGraph scan (Morphium.java:575-577) — native-image crash for that mode. One line, same as the other switch branches.

Everything else moves to follow-up issues after the merge — none of it is silent-corruption class anymore:

• Migration lock in-flight heartbeat + the wait test's lock _id (morphium_migration_lock vs migration_lock — it currently acquires a different document and never exercises the wait loop) + a real renewal test with a contender
• Private interface methods failing the build (Jandex isDefault() is public && !static && !abstract — skip anything non-abstract instead); same for abstract toString()/equals()/hashCode() redeclarations; inherited abstract methods from super-interfaces escaping the check
• One new, minor finding from the A-fix review: on SingleMongoConnectDriver a failed commit leaves the context set (it clears only after a successful execute()), so the retry's morphium.setTransaction(txContext) throws IllegalArgumentException("Transaction already in progress!") — retry never happens and the original error is masked. No data loss (the subsequent abort works), but guard it with if (attempt > 0 && morphium.getTransaction() == null).
• The CosmosDB comment from 2cce8e29b documenting the UOE "safety net" (dead code, see my earlier comment) should be corrected whenever you touch that file next
• try/catch + log around MorphiumBlockingCallDetector.registerListener(), a unit test for the new build-time Limit/PageRequest rejection, @Delete with boolean/Integer/Long returns → build-time error instead of VerifyError

Ship the two one-liners and I'll approve. If you want, collect the follow-up list into issues after the merge — happy to review those at whatever pace.

I want to include the modules into the 6.3.0 release. and because of some production issues, we need the fix rather earlier than later. Hence I'd like to release soon (today / tomorrow)

[sboesebeck]

Hi Heiko,

reviewed 43dbc2224 and 87b44e0dc. The detector redesign is the structurally right solution (static registerOn() after the connect — can't ever cause one; and it obsoletes my try/catch remark, no thread left to die), the ExecutionCondition is the correct gating mechanism, and codegen items 1–3 check out including the synthetic-index tests. But item 4 introduces a new silent regression, same failure class as the one it fixes:

Entity-parameter @Delete lifecycle methods are now silent no-ops. The parameter-name fallback in generateDeleteAnnotatedMethod marks every named parameter as a condition — and this reactor compiles with -parameters everywhere, so parameters always have names. The canonical Jakarta Data lifecycle pattern:

@Delete
void remove(CustomerEntity customer);

now takes the condition branch with conditionsSpec = "customer:0" instead of the entity branch (doDelete). Chain from there: executeAnnotatedDeleteCounted → resolveMongoField(entityClass, "customer") → getMongoFieldName throws → fallback returns the raw name (QueryExecutor.resolveMongoField, the catch returns javaFieldName) → query {customer: <entity object>} → matches nothing → query.delete() removes 0 documents and the method returns normally. Deletes nothing, looks like success. The else branch ("Single entity parameter → delegate to doDelete") is effectively unreachable now — it only triggers when parameter names are absent, which never happens in this build.

(Standard CrudRepository.delete(entity) is unaffected — that goes through the CRUD_METHODS path — it's specifically custom @Delete-annotated methods with an entity parameter. There's no integration test for that pattern, which is why the suite stayed green; the new deployment test only covers a String-typed condition param.)

Suggested fix: apply the name-fallback only to parameters whose type is not the entity type (or a List/collection of it) — an entity-typed parameter is a lifecycle delete by spec, regardless of its name. While you're there, generateDeleteAnnotatedMethod is the one generator that doesn't receive entityFields — passing it in would let you validate fallback names at build time exactly like the @Find path does, so a typo'd parameter name fails the build instead of silently matching nothing. Plus one integration test with an entity-parameter @Delete method.

And a gentle reminder since the comments may have crossed mid-work: the two one-liners from my 16:25 comment (renewLock() abort on n == 0, setIndexCheck(NO_CHECK) in the CREATE_ON_WRITE_NEW_COL branch) are still pending — those two plus this entity-delete fix are the complete remaining merge path. Everything else stays follow-up as agreed.

[Bardioc1977]

Thanks for the deep re-review — the two regressions my own fix wave introduced were exactly the kind of thing I'd rather hear now than after a merge. Status per item:

A — commit retry was a no-op and converted data loss into reported success

Confirmed and fixed. You were right about the mechanism: PooledDriver.commitTransaction() clears the context in its finally block even when the commit command failed, so safeCommit() saw getTransaction() == null on the retry and returned as success. Code 251 got the right answer by accident; code 112 silently lost every write.

safeCommitWithRetry() now snapshots the context before the first attempt and re-installs it via morphium.setTransaction() before each retry, so the retry actually re-issues the commit. I left the core-side PooledDriver change to you as agreed.

Also added the test coverage that was missing entirely for this path. This needed Mockito (test scope, version from the inherited Quarkus BOM) — hand-faking MorphiumDriver for one method wasn't maintainable. Two tests: a fake driver that mimics PooledDriver exactly (clears the context in a finally even when throwing), first commit throws 112, second succeeds, asserting commitTransaction() is invoked twice; plus code 11000 asserting it is not retried and propagates.

Test quality verified by mutation, not by passing: commenting out setTransaction(txContext) turns the first test red with expected: 2 but was: 1 — exactly the silent-success path. Restored and re-verified green.

One note: Mockito's inline mock maker cannot instrument Morphium on JDK 25 (ByteBuddy retransform failure), so these tests need JDK 21. I installed it locally but did not commit a .tool-versions pin — that's your call, not mine.

B — deleteBy/countBy/existsBy with a dynamic parameter

Confirmed, including that it's a real regression (that signature did delete before, the argument was just ignored). Root cause exactly as you described: the new 12-arg overload builds its own query and never consults descriptor.prefix().

Non-FIND prefixes now delegate to QueryExecutor.execute(). A dynamic Sort/Order on a non-FIND prefix is accepted and ignored (no result list to reorder). Limit/PageRequest on countBy/existsBy/deleteBy is rejected at build time instead — "the 3rd page of a delete" has no sensible definition, and neither countAll() nor query.delete() has a skip/limit-bounded variant, so failing the build beats silently dropping a parameter someone wrote expecting it to work. If you'd rather have it silently ignored for compatibility, say so and I'll change it.

Tests: the delete test asserts the actual document count before (3) and after (1) plus that findByStatus("OPEN") is empty — not just a plausible return value. Count and exists assert the long/boolean that previously threw ClassCastException. Gap I'm aware of: the build-time rejection itself has no automated test yet; that needs a synthetic-Jandex-index unit test in the deployment module, since a deliberately failing build can't be asserted green from integration-tests.

Blocker 2 residuals — all four fixed

• Private interface methods breaking the build (my own fix's fault — thanks for catching it, that's broken legal user code): guard now skips everything non-abstract via isAbstract() instead of isDefault(), plus an explicit skip for abstract toString/equals/hashCode redeclarations.
• @Delete returning boolean/Integer/Long: now a build-time error with a clear message instead of a VerifyError at class load.
• Methods inherited from a custom super-interface: the scan now walks interfaceTypes() recursively, with the four standard Jakarta Data interfaces treated as hierarchy dead-ends so their CRUD methods aren't misreported, and a visited-set against diamond inheritance.
• @By fallback missing in generateDeleteAnnotatedMethod: same parameter-name fallback as the @Find path now applies.

19/19 deployment-module tests green. Unit tests for these four are still outstanding — flagging that rather than implying coverage.

Blocker 6 — migration lock

renewLock() now inspects n and aborts the run on n == 0, and I corrected that inaccurate comment about subsequent writes being no-ops.

The wait test's lock-id bug was real and embarrassing — it would have stayed green with acquireLockWithWait() deleted entirely (it seeded "morphium_migration_lock" while the runner uses "migration_lock", so the polling loop was never exercised). It now references the real constant through an accessor instead of a copy-pasted literal, so renaming the constant can't blind it again.

For the in-flight steal I went with the real heartbeat rather than documenting the constraint away: a daemon thread renews the lock while a single change unit is still running, terminated in a finally, owner-guarded, with the failure surfaced instead of swallowed. Docs updated accordingly (the TTL now only needs to exceed the heartbeat interval, not the runtime of any unit).

Writing the tests for this surfaced two things worth telling you about.

A real bug in the heartbeat itself: HEARTBEAT_TICKS_PER_TTL = 3 was capped by a hard one-second floor, so with a small lockTtlSeconds the first tick fired after the TTL had already expired — the heartbeat was structurally ineffective for small TTLs, not just in tests. Fixed in the production code (floor lowered to 200ms), not by loosening the tests.

And something in morphium-core you may want to look at, since it's your side: InMemDriver lets any contender steal a still-valid lock, which means acquireLock() is not actually atomic against the in-memory driver. An upsert:true update whose filter matches nothing (because expires_at is still in the future) takes the upsert branch and seeds a document from the equality predicates only — correct, matching MongoDB. But that document then goes through storeInternal(), which treats an already-existing _id as a replace (remove(previous) + insert) rather than raising a duplicate key error. A real server would fail that upsert with E11000; insertInternal() does implement the 11000 path correctly, but the upsert never reaches it. Observed empirically first (upserted=true, n=1 against a lock whose expires_at was still in the future), then confirmed in the driver source.

That has two consequences. It's why the original lockIsRenewedBetweenMigrations could never prove anything, and it's why the obvious "a contender tries to take over and must fail" test is impossible against InMemDriver — I had to rewrite both tests to prove renewal positively instead (read the lock document mid-run, assert owner is unchanged and expires_at has moved past what the original TTL would have given). The test code documents why.

Both tests are mutation-proofed, and that turned out to matter: the first version of the between-units test stayed green with renewLock() disabled — I'd repeated exactly the mistake you called out. Cause: at a 1s TTL the heartbeat ticks every ~333ms, so with 800ms change units the heartbeat was silently renewing the lock and masking the missing between-units call. Raising that test's TTL to 6s makes the heartbeat interval (2s) longer than any single unit, which genuinely isolates the two mechanisms. Now disabling renewLock() reddens only the between-units test, and disabling the heartbeat reddens only the in-flight test — each with its own assertion, the other 8 staying green.

I have not touched morphium-core for this — flagging it rather than fixing it in a Quarkus PR.

Blocker 7 — Docker guard

Two changes. The detector no longer dereferences the Morphium proxy at all: it's not a CDI bean anymore, the StartupEvent observer and its background thread are gone, and the listener is registered from MorphiumProducer.buildMorphium() right after the connect succeeds — so it is now structurally impossible for the detector to cause a connect, rather than merely unlikely. Plus a JUnit ExecutionCondition calling DockerClientFactory.instance().isDockerAvailable() directly, which JUnit evaluates before QuarkusTestExtension boots, replacing the @BeforeAll check.

What I could not prove, and I'd rather say so than claim it: I couldn't produce a genuinely Docker-less run on this machine. Three attempts, each traced to its cause:

1. DOCKER_HOST — ignored; Testcontainers' UnixSocketClientProviderStrategy checks a hardcoded /var/run/docker.sock.
2. TESTCONTAINERS_DOCKER_SOCKET_OVERRIDE — works in isolation (isDockerAvailable() → false), but Quarkus's own guard uses ContainerRuntimeUtil.detectContainerRuntime(), i.e. the docker binary, so DockerStatusBuildItem still correctly reported available and Dev Services still tried to start a container.
3. -Dquarkus-local-container-runtime=UNAVAILABLE — also ineffective: ~/.testcontainers.properties pins the socket strategy and overrides the env var.

Which surfaces something you may care about independently: the project has two different Docker detections that can disagree — Quarkus's binary check versus Testcontainers' socket check. That's very likely also why @EnabledIfDockerAvailable misbehaved under Quarkus test classloading in the first place. If you have a working way to simulate "no Docker" on a machine that has it, I'll happily run the proof; otherwise this needs verifying on a genuinely Docker-less machine or in CI.

Smaller items

• Multi now rejected alongside Uni. While testing it I found the pre-existing Uni detection had no test at all — only CompletionStage was covered. Both are covered now, via classes defined at runtime with those exact FQNs (ByteBuddy, already on the test classpath) rather than a stub source file in the io.smallrye.mutiny package, which would have collided as a duplicate class the moment Mutiny becomes a real dependency.
• ssl.tls-configuration-name documented; a sweep confirmed the other eight ssl.* properties were already there.
• You're right that the blocker 4 commit message and the code disagree about AFTER_ROLLBACK firing for Errors. The code is deliberate (Errors propagate without a lifecycle event); the message is wrong. Noted for the message, no code change.

All six items are pushed. Final verification: full reactor clean build green, 254/254 integration tests green (0 failures, 0 errors, 0 skipped), 59/59 runtime-module and 23/23 deployment-module unit tests green.

Three things I'd flag as genuinely open rather than done:

• the build-time rejection of Limit/PageRequest on non-FIND prefixes has no automated test yet (needs a synthetic-Jandex unit test in the deployment module),
• the Docker-less run is unverified on this machine for the reasons above,
• the InMemDriver upsert/replace behaviour is yours to decide on.

And two questions back at you: whether you want a .tool-versions JDK pin committed, and whether the Limit-on-delete rejection should be a build error as I've implemented it or a silent ignore for compatibility.

[Bardioc1977]

Hi Stephan,

sorry, our AI agents were told to automatically process incoming reviews and therefore they completed everything, even though you suggested to postpone some minor fixes. However, now almost everything you mentioned has been sorted out with one question regarding InMemoryDriver Support status.

Hope its fine, that we did not stop the agent once you suggested a split in major and minor findings.

Hi Heiko,

yeah, sometimes AI agents go rogue — so you need to keep an eye on them 😉 Quick status check on the current head (83dafb862) — two of the blockers from the review round above still look unresolved to me:

1. CREATE_ON_WRITE_NEW_COL still doesn't call setIndexCheck(NO_CHECK), unlike the other three branches — core's default (WARN_ON_STARTUP) stays active and the constructor runs the live ClassGraph scan, so this mode still crashes under native-image.

morphium/quarkus-morphium/runtime/src/main/java/de/caluga/morphium/quarkus/MorphiumProducer.java

Lines 384 to 398 in 83dafb8

	switch (effectiveIndexCheck) {
	case CREATE_ON_STARTUP:
	// Disable Morphium-internal creation — Producer.ensureIndices() handles it
	cfg.collectionCheckSettings().setIndexCheck(CollectionCheckSettings.IndexCheck.NO_CHECK);
	break;
	case WARN_ON_STARTUP:
	cfg.collectionCheckSettings().setIndexCheck(CollectionCheckSettings.IndexCheck.WARN_ON_STARTUP);
	break;
	case CREATE_ON_WRITE_NEW_COL:
	cfg.setAutoIndexAndCappedCreationOnWrite(true);
	break;
	case NO_CHECK:
	cfg.collectionCheckSettings().setIndexCheck(CollectionCheckSettings.IndexCheck.NO_CHECK);
	break;
	}

2. Entity-parameter @Delete methods are still routed through the @By-condition path — the parameter-name fallback in the loop below doesn't check whether the parameter type is the entity type, so @Delete void remove(CustomerEntity customer) builds {customer: <entity>} as a query, matches nothing, and query.delete() silently removes 0 rows while returning normally.

morphium/quarkus-morphium/deployment/src/main/java/de/caluga/morphium/quarkus/deployment/MorphiumDataProcessor.java

	// Without this fallback, a @Delete method relying on parameter names alone gets

	if (methodParamName != null) {
	fieldName = methodParamName;
	}
	}
	if (fieldName != null) {
	hasByParams = true;
	if (conditionsSpec.length() > 0) conditionsSpec.append(",");
	conditionsSpec.append(fieldName).append(":").append(i);

	String[] paramTypeNames = new String[method.parametersCount()];
	for (int i = 0; i < method.parametersCount(); i++) {
	paramTypeNames[i] = toDescriptorName(method.parameterType(i));

Everything else from the review round looks addressed. Let me know if I'm looking at a stale view of these two.

[Bardioc1977]

You were right on the second one, and it was mine. On the first one I still think it's a false positive — but my earlier reasoning for that was wrong, so let me redo it properly.

2. Entity-parameter @Delete — confirmed, fixed

Exactly as you describe, and it came straight out of my own @By fallback fix. The fallback checked only whether a parameter has a name, never what its type is, so @Delete void remove(CustomerEntity customer) got claimed as a condition, built {customer: <entity>}, matched nothing, and query.delete() removed zero rows while returning normally. It worked correctly before I touched it.

The fallback now applies only when the parameter type isn't the entity itself, an array of it, or a List/Collection/Iterable of it. An explicit @By is still always honoured even on an entity-typed parameter — that's a deliberate opt-in.

I also made the mixed case (entity parameter and conditions in one method) a build-time error. The Delete javadoc in jakarta.data-api 1.0.1 defines either exactly one entity/List<E>/E[] lifecycle parameter or condition parameters, not both, so there's no semantics to implement and guessing one seemed worse than failing loudly. Say the word if you'd rather have it accepted with defined behaviour.

Tests: 4 unit tests over a synthetic Jandex index (isEntityParameter across all type shapes plus negatives, entity-parameter delete is not a condition delete, both cases asserted side by side, and the mixed-case rejection), plus an integration test asserting the actual document count before and after the call with a per-customer cross-check — the test that would have caught this in the first place.

I mutation-proofed it instead of trusting the green run, and that was instructive: with the type check disabled the build fails, because remove(OrderEntity) is then misread as a condition parameter and trips the new mixed-case rejection. The two guards compose, so even a broken type check can't resurrect the silent-delete path.

One thing I did not do: the entity branch still only handles a single entity via doDelete(Object), not List<E>/E[] via doDeleteAll(List). That gap predates this bug (it was there before my fallback too), so I left it out rather than bundling an unrelated feature into a regression fix. Happy to add it if you want it in this PR.

1. CREATE_ON_WRITE_NEW_COL — still a false positive, but my old argument was wrong

I owe you a correction here. When I dismissed this the first time I claimed setAutoIndexAndCappedCreationOnWrite(true) overrides the index check to NO_CHECK. That's simply false — MorphiumConfig line 509-511 sets it to CREATE_ON_WRITE_NEW_COL. So my reasoning was wrong even though I landed on the right answer, which is exactly the kind of thing that deserves being called out.

The actual reason no setIndexCheck(NO_CHECK) is needed: the ClassGraph scan lives in checkIndices(), and its only startup call site is guarded to two modes specifically —

Morphium.java:575-576:

if (!...getIndexCheck().equals(IndexCheck.NO_CHECK) && (...equals(IndexCheck.CREATE_ON_STARTUP) ||
        ...equals(IndexCheck.WARN_ON_STARTUP))) {
    Map<Class<?>, List<IndexDescription>> missing = checkIndices(...);   // line 577, the scan

CREATE_ON_WRITE_NEW_COL isn't in that condition, so the scan never runs and the constructor never touches ClassGraph. Core's default WARN_ON_STARTUP doesn't stay active either — setAutoIndexAndCappedCreationOnWrite(true) has already replaced it with CREATE_ON_WRITE_NEW_COL by then. The index/capped creation for this mode happens later on the write path via ensureIndicesFor, which uses plain reflection through AnnotationAndReflectionHelper, not ClassGraph.

So the branch looks asymmetric next to the other three, and I understand why it reads as an oversight, but the asymmetry is load-bearing: adding setIndexCheck(NO_CHECK) there would overwrite the very value that makes the mode work.

If you'd still prefer it explicit, the honest version would be a comment on that branch explaining why it deliberately doesn't set the check — I'm glad to add that, since this is now the second time the branch has looked wrong to a reader.

Also in this push

Three findings from the Copilot review that finally came through (its earlier attempts were erroring out server-side):

• A test named "Entity without @Version" used ItemEntity, which has @Version, and asserted getVersion() == 2 — it verified the opposite of its name. There's now a real UnversionedEntity, and the test proves the actual behaviour: a concurrent client updates the document in between and the stale reference still stores instead of throwing VersionMismatchException.
• Two tests in MorphiumStartupCheckTest asserted an identical condition; removed the duplicate (the remaining four already cover all boolean combinations).
• MongoDBStartable recompiled the same regex per call; hoisted to a constant.

Two Copilot suggestions I deliberately declined: switching MorphiumTransactionEvent to Throwable would change a public API for a case that intentionally fires no event (Errors propagate without a lifecycle event, as we discussed), and the missing license header on StatusStats matches existing practice in that module.

Head is now 7bbe7c790. Clean reactor build green, 255/255 integration tests, 27/27 deployment and 58 runtime unit tests.

Hi Heiko,

good progress on the latest wave — the entity-parameter @Delete fix (f81e5881) is correct: isEntityParameter() keeps the fallback off entity-typed params, the build-time rejection for mixing entity + @By params is a nice touch, and the boolean/Integer/Long VerifyError guard came along for free. Migration lock and the Copilot cleanup wave (7bbe7c79) look good too.

One item left: CREATE_ON_WRITE_NEW_COL still doesn't call setIndexCheck(NO_CHECK) — same spot as before.

You were right, and I was wrong twice — in two different ways. Fixed in 6137e09f8, and here's the full chain, because the interesting part is what I kept missing.

Where I went wrong

First dismissal: I claimed setAutoIndexAndCappedCreationOnWrite(true) overrides the index check to NO_CHECK. Plainly false — MorphiumConfig lines 509-511 set both the index check and the capped check to CREATE_ON_WRITE_NEW_COL.

Second dismissal: I then verified that checkIndices()' ClassGraph scan is gated to CREATE_ON_STARTUP/WARN_ON_STARTUP (Morphium.java:575-576) and concluded there was no scan. That gating is real — but there is a second scan I never looked at:

// Morphium.java:529 — no mode gate at all
var capped = checkCapped();

checkCapped() (line 3354) scans at line 3358 via ClassGraphCache.getClassesWithAnnotation(Capped.class). The switch below it treats CREATE_ON_WRITE_NEW_COL as a no-op, but by then the scan has already run. The root cause of my blindness: that setter writes two values, and I only ever followed the index one.

What tracing it fully changed

Following the chain to the end does shift the severity, and I want to be straight about that rather than overstate the fix: buildMorphium() already pre-registers the build-time @Capped list into ClassGraphCache before the Morphium constructor runs, and getClassesWithAnnotation() returns a pre-registered entry without scanning — including an empty one, and cappedClassNames defaults to Collections.emptyList(), never null. So the scan was in practice already unreachable and native images were not actually crashing here.

That doesn't make your point wrong, it makes it a latent one: the branch leaves both checks on CREATE_ON_WRITE_NEW_COL and relies entirely on that pre-registration ordering holding. Fixing it is cheap and removes the dependency.

The fix

Both checks are now forced to NO_CHECK when ImageMode.current() is NATIVE_RUN — note both, since disabling only setIndexCheck as you suggested would have left checkCapped() reachable. A native run can't create collections on the fly anyway, so nothing of value is disabled, and the branch is symmetric with the other three again.

The JVM path is deliberately untouched. There the scan is a startup cost, not fatal, and switching it off would defeat the entire purpose of the mode for every JVM user. If you'd rather have it off there too for startup time, that's your call.

The comment now spells all of this out — cause, why the pre-registration already covers it, and why the guard is still there — so the branch doesn't read as an oversight a fourth time.

Five unit tests, including a JVM counter-test asserting both checks stay on CREATE_ON_WRITE_NEW_COL, so the fix can't silently break the mode. Mutation-proofed: disabling the native guard reddens exactly the native test on its own assertion, the other four stay green.

Verification

Clean reactor build green, 63/63 runtime tests (58 + 5 new), 27/27 deployment, 255/255 integration — 0 failures, 0 errors, 0 skipped.

Thanks for pushing on this three times instead of letting it go. Two of my "verified false positive" calls in this PR turned out to be incomplete analysis, which is a good argument for you keeping the sceptical eye on the ones I'm still claiming.

[sboesebeck]

Hi Heiko,

all three blockers are cleanly resolved now, and the CREATE_ON_WRITE_NEW_COL fix went further than what was actually asked for — catching the checkCapped() gap most people (myself included) would have missed, and backing it with a mutation-proofed test so it can't regress silently. That's exactly the kind of thoroughness this extension deserves.

Genuinely impressed by this whole PR: a clean module split, careful attention to native-image and Dev Services edge cases, and — maybe the best part — you took a deep, occasionally uncomfortably thorough review completely in stride, fixed everything properly instead of the fast/shallow version, and even called out where the review itself had gaps. That's a rare combination. Thank you for the effort and the patience.

Merging now. Really looking forward to quarkus-morphium shipping in 6.3.0 — and to spring-boot-morphium after it.

[Bardioc1977]

Hi Stephan,

please hold back releasing 6.3.0 - We've come up with a regression in two of our applications when switching to the 6.3.0-SNAPSHOT. As far as I see its a very old bug. A fix is on the way.

[sboesebeck]

yes - I was running the whole test suite anyways and found a flaky test I want to investigate. I will post an announcement before creating the release! 😉

I let Copilot do its first round on our fork:
