Problem

S3 client settings such as s3.client.default.disable_chunked_encoding were defined
but not consistently registered, causing OpenSearch to fail with unknown setting
errors during startup.

Solution

  • Introduce S3ClientSettings.getAllClientSettings() as a single source of truth
  • Update S3RepositoryPlugin to rely on it instead of maintaining a duplicate list
  • Ensure all client settings are registered, including disable_chunked_encoding

Testing

  • ./gradlew :plugins:repository-s3:test

Summary by CodeRabbit

  • Bug Fixes

    • Fixed missing registration of S3 repository client settings that could cause unknown-setting errors when configuring S3 repositories.
  • New Features

    • Added a consolidated accessor exposing all S3 client settings for centralized configuration.
  • Tests

    • Added a verification test ensuring all S3 client settings are consistently registered.
  • Documentation

    • Updated changelog entries related to S3 settings and networking notes.

✏️ Tip: You can customize this high-level summary in your review settings.

📝 Walkthrough

Walkthrough

Added a new accessor S3ClientSettings.getAllClientSettings() returning all S3 client Setting constants; updated S3RepositoryPlugin.getSettings() to use that accessor and append repository-level settings; added a unit test verifying the accessor; updated CHANGELOG.

Changes

Cohort / File(s) Summary
Settings centralization
plugins/repository-s3/src/main/java/org/opensearch/repositories/s3/S3ClientSettings.java
Added static Collection<Setting<?>> getAllClientSettings() which returns a fixed list of all S3 client Setting<?> constants (access keys, session token, endpoint/protocol, proxy_*, timeouts, connection limits, retries, signer/region/role/identity settings, legacy flags, etc.).
Plugin settings composition
plugins/repository-s3/src/main/java/org/opensearch/repositories/s3/S3RepositoryPlugin.java
Reworked getSettings() to build a mutable list: add all entries from S3ClientSettings.getAllClientSettings() then append repository-level settings (changed internal construction and ordering).
Unit test
plugins/repository-s3/src/test/java/org/opensearch/repositories/s3/S3ClientSettingsTests.java
Added testGetAllClientSettings() which reflects over static Setting fields in S3ClientSettings and asserts equality with getAllClientSettings() output.
Changelog
CHANGELOG.md
Added an Unreleased Fixed entry: "Fix missing registration of repository-s3 client settings to prevent unknown setting errors".

97-111: Well-designed test that will catch the missing settings bug.

This reflection-based test correctly validates that getAllClientSettings() returns all declared static Setting fields. When run, it will fail due to the 7 missing settings in getAllClientSettings().

Consider adding a descriptive message to the assertion to help diagnose failures:

🔎 Optional: add assertion message
     assertEquals(
+        "getAllClientSettings() must return all static Setting fields declared in S3ClientSettings",
         Set.copyOf(reflectedSettings),

Learning: In the OpenSearch ReactorNetty4 secure HTTP transport tests (plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ssl/SecureReactorNetty4HttpServerTransportTests.java), URI limit validation has been moved from the protocol layer to the transport layer, making it protocol-agnostic. The random protocol selection in ReactorHttpClient.https(settings) is intentional to ensure all tests validate correct behavior across HTTP/1.1, HTTP/2, and HTTP/3.

55-55: Wildcard import is acceptable for internal consistency.

This change aligns with the pattern used elsewhere in the codebase, though explicit imports are generally preferred for clarity.

plugins/repository-s3/src/main/java/org/opensearch/repositories/s3/S3RepositoryPlugin.java (1)

346-366: Clean refactor delegating to S3ClientSettings.getAllClientSettings().

The separation of client-level and repository-level settings improves maintainability. However, this will only work correctly once the missing settings in getAllClientSettings() are added.
