Summary
Complete PHP client implementation for RocketMQ, claiming production-ready status with all core features: standard/FIFO/scheduled/transaction message producers, SimpleConsumer, PushConsumer (concurrent + FIFO), priority messages, and lite consumer support. This is a massive PR (~35,600 lines).
Findings
-
[Warning] PR Size: At ~35,600 lines across 100+ files, this PR is far too large for effective code review. A thorough review of this scope is not feasible in a single pass. Consider splitting into multiple PRs by feature area:
- Core client infrastructure (gRPC connection, auth, config)
- Producer implementations (standard, FIFO, scheduled, transaction)
- Consumer implementations (SimpleConsumer, PushConsumer, LitePushConsumer)
- Tests and documentation
-
[Warning] Feature parity verification: The PR claims full feature parity with Java/Go/C++ clients. This needs verification against the protocol specification, especially for:
- Transaction message two-phase commit protocol
- FIFO message ordering guarantees
- Lite consumer partition assignment protocol
-
[Info] The PR includes unit tests, which is good for a feature of this size.
-
[Warning] gRPC protocol compliance: The PHP client must adhere to the same gRPC protocol as defined in the Proxy module of
apache/rocketmq. Any deviation could cause interoperability issues.
Suggestions
- Strongly recommend splitting into 3-4 smaller PRs for reviewability.
- Add integration tests that verify protocol compliance against a real RocketMQ Proxy.
- Consider having maintainers from the Java/Go client teams review for protocol consistency.
- Update the feature matrix in README only after all sub-PRs are merged and verified.

Thanks for the PHP client update. I found several correctness and CI issues that should be addressed before this can be merged. The main blockers are masked Windows test failures, startup paths that proceed without confirmed server state, and transaction/lite-consumer behavior that can report success while leaving required work undone.

This makes the Windows leg unable to fail: any PHPUnit failure is converted to success. If the gRPC extension has a known shutdown-only issue, please gate that workaround narrowly, for example by detecting that specific shutdown failure, or isolate/skip the affected tests, instead of appending exit 0 to the whole test command.

A settings stream error is treated as success here. Producer::start() and the consumer startup paths rely on syncSettings() to decide whether the client is ready, so this can mark the client running without server-accepted settings such as backoff, message type, assignment, or transaction callbacks. Please return failure/throw on stream error, and apply the same rule to the timeout path, unless every operation is guarded until settings are actually confirmed.

The builder-level LocalTransactionExecuter is never used here; only the per-call $executor is checked. A producer configured through ProducerBuilder::setLocalTransactionExecuter() will send the half message but never execute/commit/rollback the local transaction unless the caller passes another executor to this method. Please use $executor ?? $this->localTransactionExecuter.

Failures from SyncLiteSubscription are only logged, and the caller continues startup. This can leave the consumer running without server-side lite subscriptions or assignments. syncLiteSubscriptions() should return/throw on non-OK status and the startup path should fail rather than proceeding silently.

empty() rejects "0", which is a valid non-empty message body in PHP. This validator is stricter than MessageBuilder's null-only body check. Please use a strict empty-string check, such as $body === '' or strlen($body) === 0.

The generated enum values for these lite quota errors are 42901/42902, not 40901/40902. With the current mapping, server responses with LITE_TOPIC_QUOTA_EXCEEDED or LITE_SUBSCRIPTION_QUOTA_EXCEEDED will fall through to the generic 4xx exception path instead of the specific lite quota exceptions.

This convenience API bypasses the priority range validation that MessageBuilder::setPriority() applies (1..9). Invalid priorities can be sent directly through this method. Please reuse the same validation here or route through the builder method.

I found several correctness and interoperability issues that should be addressed before this PHP client is considered production-ready. Details are inline.
| if ($attempt > 1 && $candidateCount > 1) { | ||
| $queueIndex = IntMath::mod($attempt, $candidateCount); | ||
| $currentMessageQueue = $candidates[$queueIndex]; | ||
| $request = $this->wrapSendMessageRequest([$message], $currentMessageQueue); |
There was a problem hiding this comment.
This retry path always rebuilds the request with wrapSendMessageRequest(), even when the original request was created by wrapTransactionMessageRequest(). After a transient failure, a half message can therefore be retried as a normal, immediately visible message, and the result may no longer contain a valid transaction ID. TransactionTrait also records the endpoint of $messageQueue[0] instead of the queue that actually succeeded. Please preserve the original message type during retries and return/use the successful queue endpoint for transaction tracking.

| $computed = ''; | ||
| if ($digestType === \Apache\Rocketmq\V2\DigestType::CRC32) { | ||
| $computed = sprintf('%u', crc32($body)); |
There was a problem hiding this comment.
sprintf('%u', crc32($body)) produces a decimal checksum, while RocketMQ CRC32 digests use uppercase hexadecimal; Utilities::crc32CheckSum() already implements the expected format. In addition, processBody() currently verifies the digest after GZIP decompression, although the digest covers the encoded body bytes. As written, valid messages can be marked corrupted and NACKed. Please verify the raw body before decompression and reuse the existing checksum helper.

| private function makeKey(string $endpoints, array $options): string | ||
| { | ||
| $tlsFingerprint = 'insecure'; |
There was a problem hiding this comment.
The cache key does not include sslEnabled. When neither tlsCredentials nor pre-created credentials is provided, both the default TLS configuration and sslEnabled=false produce the same <endpoint>:insecure key. The channel created first is then reused for the other configuration, which can silently make a TLS client use a plaintext channel. Please include the resolved transport/TLS mode in the cache key.
| $command = new TelemetryCommand(); | ||
| $command->setSettings($settings); | ||

|
||
| $success = $this->telemetrySession->createStreamAndSync($command); |
There was a problem hiding this comment.
createStreamAndSync() only creates the telemetry stream and writes the Settings command; it does not wait for the server Settings response. Therefore the earlier syncSettings() timeout/error fix still does not protect PushConsumer startup, and consumption can begin without server-accepted settings or backoff values. Please use syncSettings() here, or otherwise wait for and validate the server response before marking startup successful.

| return; |
There was a problem hiding this comment.
An empty assignment set is a valid rebalance result, for example when all queues are reassigned to other consumers. Returning here keeps every existing ProcessQueue active, so this client continues fetching queues it no longer owns and may cause duplicate/competing consumption. Please allow the removal loop below to clear this topic's existing queues when the new assignment set is empty.

This is not compatible with Hashing.sipHash24() in Guava: Guava uses the fixed key bytes 00..0f, not an all-zero key, and SipHash input words are little-endian while readLong() currently places the first input byte in the most-significant position. Consequently, the same message group can map to different queues in PHP and the Java/Node clients, breaking cross-language FIFO ordering. Please use the standard key/byte order and add known SipHash vectors plus cross-client queue-selection tests.

This named suite explicitly excludes tests/integration, and the workflow never invokes RocketMQ PHP Integration Tests. The current telemetry timeout integration test already disagrees with the updated implementation, but CI cannot detect that regression. Please add a separate integration-test step/job (or run both suites) rather than reporting only the unit suite as the PHP build result.
…ebalance, digest and tx retry - SipHash24: align with Guava Hashing.sipHash24() (fixed key bytes 00..0f, little-endian input words); fix v2 init constant, rotl64 sign extension and add64 float overflow; add reference vectors and cross-client queue-selection tests - PushConsumer: empty assignment now clears the topic's process queues; startup uses syncSettings() to wait for server-accepted settings - RpcClientManager: channel cache key includes resolved TLS/transport mode so default-TLS never reuses a plaintext channel - MessageView: verify body digest on raw (encoded) bytes before GZIP decompression and reuse Utilities::crc32CheckSum() hex format - SendMessageHandler/TransactionTrait: retries preserve the transaction message type and the result reports the successful queue endpoint for transaction tracking - CI: run the PHP integration test suite in php_build workflow
…down workaround
With skipped tests PHPUnit prints 'OK, but incomplete, skipped, or risky
tests!' instead of 'OK (N tests ...)', so the integration suite's grep
never matched and the segfault-on-shutdown exit code 139 failed the step
even though all 108 tests passed. Accept both success formats; failures
and errors ('FAILURES!'/'ERRORS!') still propagate.
