dennis zhuang b913be2af7 fix(promql): return range-vector results for instant queries (#9477)
* fix(promql): return range-vector results for instant queries

An instant query of a range selector or subquery (e.g. `up[5m]`) returned
the internal range arrays, which panicked when the frontend decoded them as
dictionaries. Plan such queries as the selected samples with their own
timestamps, and reject range-vector expressions in range queries like
Prometheus does.

* test(promql): keep encode_substrait on a valid range query

A range query of a range-vector expression now fails like in Prometheus.
Wrap the subquery in max_over_time so the case still encodes both
RangeManipulate nodes through substrait.

* fix(promql): plan wrapped range-vector roots and reject a zero subquery step

TQL EXPLAIN, ANALYZE and AS alias wrap the root in an extension, which the
range-vector path did not unwrap. A zero subquery step divided by zero.

* test(promql): cover wrapped range-vector roots and a zero subquery step

* fix(promql): default subquery step and reject range vectors in range queries

A root subquery without a step uses the one-minute default instead of
the query step. The HTTP range query endpoint rejects range-vector
expressions even when start equals end.

Setup tests for multiple storage backend

To run the integration test, please copy .env.example to .env in the project root folder and change the values on need.

Take s3 for example. You need to set your S3 bucket, access key id and secret key:

# Settings for s3 test
GT_S3_BUCKET=S3 bucket
GT_S3_REGION=S3 region
GT_S3_ACCESS_KEY_ID=S3 access key id
GT_S3_ACCESS_KEY=S3 secret access key

Run

Execute the following command in the project root folder:

cargo test integration

Test s3 storage:

cargo test s3

Test oss storage:

cargo test oss

Test azblob storage:

cargo test azblob

Setup tests with Kafka wal

To run the integration test, please copy .env.example to .env in the project root folder and change the values on need.

GT_KAFKA_ENDPOINTS = localhost:9092

Setup kafka standalone

cd tests-integration/fixtures

docker compose -f docker-compose.yml up kafka

Setup tests with etcd TLS

This guide explains how to set up and test TLS-enabled etcd connections in GreptimeDB integration tests.

Quick Start

TLS certificates are already at tests-integration/fixtures/etcd-tls-certs/.

  1. Start TLS-enabled etcd:

    cd tests-integration/fixtures
    docker compose up etcd-tls -d
    
  2. Start all services (including etcd-tls):

    cd tests-integration/fixtures
    docker compose up -d --wait
    

Certificate Details

The checked-in certificates include:

  • ca.crt - Certificate Authority certificate
  • server.crt / server-key.pem - Server certificate for etcd-tls service
  • client.crt / client-key.pem - Client certificate for connecting to etcd-tls

The server certificate includes SANs for localhost, etcd-tls, 127.0.0.1, and ::1.

Regenerating Certificates (Optional)

If you need to regenerate the etcd certificates:

# Regenerate certificates (overwrites existing ones)
./scripts/generate-etcd-tls-certs.sh

# Or generate in custom location
./scripts/generate-etcd-tls-certs.sh /path/to/cert/directory

If you need to regenerate the mysql and postgres certificates:

# Regenerate certificates (overwrites existing ones)
./scripts/generate_certs.sh

# Or generate in custom location
./scripts/generate_certs.sh /path/to/cert/directory

Note: The checked-in certificates are for testing purposes only and should never be used in production.
