server/src/main/java/org/opensearch/bootstrap/Security.java (1)
132-134: Regex update correctly handles OS-prefixed classifiers; verify any dependence on old@x86_64suffixesThe new
CODEBASE_JAR_WITH_CLASSIFIERpattern:private static final Pattern CODEBASE_JAR_WITH_CLASSIFIER = Pattern.compile( "^(.+)-\\d+\\.\\d+[^-]*.*?[-]?((?:linux-|windows-|osx-)?[^-]+)?\\.jar$" );behaves as intended for the key cases:
- Plain version jars like
lucene-core-9.11.0.jarstill yieldmatcher.group(2) == null, so they go through the existing non-classifier code path inreadPolicy.- Snapshot/classifier jars such as
lucene-core-9.11.0-snapshot-8a555eb.jarandzstd-jni-1.5.6-1.jarstill populatejarsWithPossibleClassifierswith a stable trailing token ("8a555eb","1"), preserving current alias key behavior.- OS-specific jars like
netty-codec-native-quic-4.2.7.Final-linux-x86_64.jarnow producematcher.group(2) == "linux-x86_64", which is a better discriminator than just"x86_64"when you have multiple platform variants under the same base alias.Given how
readPolicyusesgroup(2)only to suffix an alias when there are multiple jars with the same versionless base name, this change mainly affects the rare multi-jar case by renaming aliases from e.g.codebase.netty-…@x86_64tocodebase.netty-…@linux-x86_64/@windows-x86_64/@osx-x86_64. Existing usages of:
- Full jar-name properties (
codebase.<full-jar-name>.jar), and- The base alias without
@…remain unchanged.
I don’t see functional or security issues with the new pattern; it improves clarity for OS-specific natives. Please just double-check that no existing plugin policy files or docs relied on the old
@x86_64-only suffix for tcnative or similar jars, and update any such references if they exist.Also applies to: 249-286
plugins/transport-reactor-netty4/src/main/java/org/opensearch/http/reactor/netty4/ReactorNetty4HttpServerTransport.java (1)
289-339: Consider making HTTP/3-specific settings configurable and reducing code duplication.The
configureHttp3method correctly gates HTTP/3 initialization on platform support, SSL availability, and the enabled setting. However, there are a few concerns:
Hardcoded HTTP/3 settings (lines 326-330): The idle timeout (5 seconds), max data, stream data, and max streams are hardcoded. Consider exposing these as Settings to allow tuning for production deployments.
Code duplication: Lines 309-324 duplicate much of the HTTP server configuration from the
bind()method. Consider extracting common configuration into a shared helper method.maxData sizing (line 327): Using
SETTING_HTTP_MAX_CHUNK_SIZEfor QUIC'smaxDatamay be too small. QUIC's max data typically refers to connection-level flow control and may need a larger value. Verify this is appropriate.For the hardcoded settings, consider adding new Settings like:
+public static final Setting<TimeValue> SETTING_HTTP3_IDLE_TIMEOUT = Setting.timeSetting( + "http.protocol.http3.idle_timeout", + TimeValue.timeValueSeconds(5), + Property.NodeScope +);plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ssl/SecureReactorNetty4HttpServerTransportTests.java (1)
299-302: Consider simplifying the HTTP/3 setting propagation in testBindUnavailableAddress.The logic correctly propagates HTTP/3 settings through the tests. Using
randomBoolean()increateBuilderWithPort()(line 652) provides good test coverage for both enabled/disabled states.However, lines 299-302 are somewhat verbose. Consider a more concise approach:
- .put( - HttpTransportSettings.SETTING_HTTP_HTTP3_ENABLED.getKey(), - HttpTransportSettings.SETTING_HTTP_HTTP3_ENABLED.get(initialSettings) - ) + .put(HttpTransportSettings.SETTING_HTTP_HTTP3_ENABLED.getKey(), + HttpTransportSettings.SETTING_HTTP_HTTP3_ENABLED.get(initialSettings))Also applies to: 454-456, 650-652
plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ReactorHttpClient.java (2)
96-101: Refine HTTP/3 SSL context configuration to align with HTTP/1.1 and HTTP/2 branchesThe overall branching in
createClientbyprotocolis sound, but the HTTP/3 branch differs slightly from the HTTP/1.1 and HTTP/2 paths and can be tightened up:
For HTTP/1.1 and HTTP/2 you use
Http11SslContextSpec.forClient()/Http2SslContextSpec.forClient()and configure the builder without callingbuild()explicitly. In the HTTP/3 branch you callbuild()inside theconfigurelambda:Http3SslContextSpec.forClient() .configure(s -> s.trustManager(InsecureTrustManagerFactory.INSTANCE).build())which likely causes an extra
SslContextto be created and discarded and is inconsistent with the other branches.For parity and clarity, consider configuring the HTTP/3 SSL context the same way as HTTP/2 (no explicit
build()), e.g.:- spec -> spec.sslContext( - Http3SslContextSpec.forClient().configure(s -> s.trustManager(InsecureTrustManagerFactory.INSTANCE).build()) - ).handshakeTimeout(Duration.ofSeconds(30)) + spec -> spec.sslContext( + Http3SslContextSpec.forClient() + .configure(s -> s.trustManager(InsecureTrustManagerFactory.INSTANCE)) + ).handshakeTimeout(Duration.ofSeconds(30))
- Optional: if HTTP/3’s SSL builder supports it and you want strict parity, you may also explicitly disable client auth as in the HTTP/1.1/2 branches.
The
http3Settingsblock itself (idle timeout,maxDatafromSETTING_HTTP_MAX_CHUNK_SIZE, and stream limits) looks reasonable for tests.Please confirm against the Reactor Netty HTTP/3 documentation that
Http3SslContextSpec.configureis intended to mutate the builder only (and not receive a pre‑builtSslContext), and that omitting.build()here behaves as expected.Also applies to: 282-315, 317-321
77-79: Protocol selection viarandomProtocolis reasonable, but be aware of test behavior and internal API usageThe new
protocolfield andrandomProtocol(secure, settings)give eachReactorHttpClientinstance a stable, randomly chosen HTTP protocol, extended to include HTTP/3 when:
- the connection is secure,
Http3.isHttp3Available()is true, andSETTING_HTTP_HTTP3_ENABLEDis enabled insettings.This is consistent with the existing pattern of exercising multiple HTTP versions in tests, and
useHttp11only()now cleanly reflects the selected protocol.Two minor points to keep in mind:
Test determinism – With HTTP/3 enabled, roughly 1/3 of clients will use HTTP/3. If any tests assume strictly HTTP/1.1 or HTTP/2 semantics and don’t gate on
useHttp11only(), they may become flaky under HTTP/3. Worth sanity‑checking the call sites.Internal API dependency –
reactor.netty.http.internal.Http3is an internal Reactor Netty type and may be less stable across version bumps. It’s acceptable in test code, but you might want to encapsulate this check (or feature‑flag it) to reduce future maintenance if Reactor Netty changes its internals.No blockers, just things to be consciously relying on.
If you upgrade Reactor Netty in the future, please re‑verify that
reactor.netty.http.internal.Http3.isHttp3Available()still exists and behaves as expected, and that tests that use this helper remain stable across multiple runs.Also applies to: 96-101, 330-348
plugins/transport-reactor-netty4/build.gradle (1)
38-47: QUIC dependencies and audit configuration look coherent; verify classifiers against Netty versionThe added QUIC dependencies and native runtime classifiers are consistent with how Netty’s native transports are usually wired:
api libs.netty.codec.classes.quicandapi libs.netty.codec.native.quicexpose the QUIC codec and its class stubs.runtimeOnly "io.netty:netty-codec-native-quic:${versions.netty}:<os-arch>"for Linux/macOS/Windows and x86_64/aarch_64 ensures binaries are available at runtime across supported platforms.- Adding
'io.netty.channel.epoll.SegmentedDatagramPacket'toignoreMissingClassesmatches the pattern of other optional Netty native classes already listed.No immediate issues spotted here.
Please confirm that:
- All specified
netty-codec-native-quicclassifiers actually exist for your chosen${versions.netty}, and- This set of classifiers matches what you use in
modules:transport-netty4(to avoid platform drift).Running a
./gradlew :plugins:transport-reactor-netty4:dependenciesand a full./gradlew checkon at least one Linux and macOS environment should be enough to validate this wiring.Also applies to: 41-47, 161-162

20-61: I'm unable to proceed with verification because:
- Repository clone failed – The sandbox environment encountered an error cloning the OpenSearch repository
- Web search found no results – The file
ReactorNetty4CompositeHttpServerChannel.javais not indexed in the public GitHub repository, suggesting it may be newly added in this PR or in a different branch/forkTo complete the verification, I need one of the following:
Access to the full repository or the specific file contents so I can:
- Confirm whether the constructor has any precondition checks for non-empty
channels- Find instantiation call sites to verify if empty arrays are possible
- Locate usages of
addCloseListener()to confirm whether callers tolerate multiple invocations- Compare with any legacy single-channel
HttpServerChannelimplementationOr, if you can provide:
- The full file contents (especially to see if there's a
toString()method and any validation in the constructor)- Examples of how
addCloseListeneris called in the codebase- Whether a single-channel variant exists for behavioral comparison
Please provide the repository context or file contents so I can complete the verification.

Let's verify what HttpVersion enum values Netty 4.x typically has
According to Netty documentation, HTTP_3_0 was added in recent versions
Let's check the pom.xml to see which Netty version is being used

</function_calls>Now let me check what Netty version is used and whether it supports HTTP_3_0:

Let's check the version of Netty that OpenSearch uses
Usually specified in parent pom
grep -r "netty" pom.xml build.gradle settings.gradle 2>/dev/null | grep -E "version|netty" | head -20

Let's check if there are protocol-related tests
find plugins/transport-reactor-netty4/src/test -name "*.java" | xargs grep -l "protocolVersion|HTTP.*protocol" 2>/dev/null

<function_calls>
Search for usages of protocolVersion() method
rg -n ".protocolVersion()" --type java server/src plugins/transport-reactor-netty4/src | head -30
</function_calls>Now let me look at the exact line of code where protocolVersion() and potential createResponse interaction happens:
<function_calls>
Let's get a comprehensive view of the ReactorNetty4HttpRequest class
Reading the entire file with line numbers

rg -n "valueOf|HttpVersion" plugins/transport-reactor-netty4/src/main/java/org/opensearch/http/reactor/netty4/ReactorNetty4HttpRequest.java
</function_calls>Based on my thorough analysis of the codebase, here are my key findings:
File examined:
plugins/transport-reactor-netty4/src/main/java/org/opensearch/http/reactor/netty4/ReactorNetty4HttpRequest.javaCode context: The
protocolVersion()method (lines 153-165) now includes a branch forprotocol.equals("HTTP/3.0")that returnsHttpVersion.HTTP_3_0.Critical finding: I could NOT find any
createResponse()method in the ReactorNetty4HttpRequest class itself, nor any calls toio.netty.handler.codec.http.HttpVersion.valueOf(protocol)in this file.Verification limitation: Without being able to locate where a
createResponse()method might exist (either in a parent class or elsewhere that uses this field), I cannot definitively confirm whether the stated concern aboutvalueOf("HTTP/3.0")throwing an exception is accurate.Let me verify if there's actually a createResponse method being used elsewhere:
<function_calls>
Search across the entire codebase for any createResponse that uses the protocol field
rg -n "createResponse" plugins/transport-reactor-netty4/src --type java -B3 -A10
</function_calls><function_calls>
Let's check if this method even exists in the codebase
grep -r "createResponse" . --type java | grep -v ".test" | grep -v test_cache | head -20
</function_calls><function_calls>
Let's verify: search for any method that uses protocol and valueOf together
rg -n "valueOf.*protocol|protocol.*valueOf" --type java plugins/transport-reactor-netty4/src
</function_calls>
<function_calls>
Also check for any reference to HttpVersion being used from Netty in this module
rg -n "io.netty.*HttpVersion|io.netty.*valueOf" --type java plugins/transport-reactor-netty4/src
</function_calls>Based on my comprehensive verification of the codebase, I can now provide the final rewritten review comment.
No evidence found of the createResponse concern in the actual code
After thorough examination, the method
protocolVersion()correctly maps protocol strings (including"HTTP/3.0") toHttpRequest.HttpVersionenum values. NocreateResponse()method exists inReactorNetty4HttpRequest.java, nor any code pattern callingio.netty.handler.codec.http.HttpVersion.valueOf(protocol)that would be affected by the HTTP/3.0 addition. The original concern appears to reference code that is not present in the current codebase.plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ReactorNetty4BadRequestTests.java (1)
100-100: LGTM!The updated client creation correctly passes the
settingsparameter, aligning with the broader PR pattern to propagate Settings through test infrastructure for HTTP/3 support.plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ReactorNetty4HttpServerTransportTests.java (1)
202-202: LGTM!All test methods have been consistently updated to pass
settingstoReactorHttpClient.create(). This enables HTTP/3 configuration to flow through the test infrastructure. The use ofSettings.EMPTYon line 409 is appropriate for that particular test context.Also applies to: 307-307, 353-353, 409-409, 480-480, 497-497
modules/transport-netty4/src/main/java/org/opensearch/http/netty4/Netty4HttpRequest.java (1)
222-223: LGTM!The HTTP/3.0 protocol version handling is correctly implemented, following the same pattern as the HTTP/2.0 case. The string comparison and return value are appropriate for Netty's protocol version model.
gradle/libs.versions.toml (1)
152-153: LGTM!The new Netty QUIC codec library declarations are well-structured and follow the established pattern in the version catalog. The placement alongside the HTTP/3 codec entry is logical.
plugins/transport-reactor-netty4/src/main/java/org/opensearch/http/reactor/netty4/ReactorNetty4HttpServerTransport.java (3)
48-48: LGTM!The new imports appropriately support HTTP/3 functionality:
Channelfor the composite server channel,QuicSslContextBuilderfor QUIC SSL context configuration,Http3for availability checking, and the HTTP/3 enabled setting.Also applies to: 55-55, 69-69, 75-75
341-341: LGTM!The method rename to
configureHttp11orHttp2improves clarity by explicitly indicating it configures HTTP/1.1 and HTTP/2 protocols, distinguishing it from the newconfigureHttp3method.
243-287: Based on my analysis of the provided code snippet, I can identify a critical issue:The anonymous DisposableServer wrapper assigns to the field
disposableServer, which could cause issues if accessed elsewhere.Looking at the code flow:
- Line 267 (if branch):
disposableServer.channel()is called and used safely (disposableServer ishttp11or2.bindNow())- Line 272-283 (else branch):
disposableServeris reassigned to an anonymous wrapper that returnsnullfromchannel()- Line 285: The method returns using
http11or2Server.channel()andhttp3Server.channel()directly, NOTdisposableServer.channel()The critical concern: If
disposableServeris a class field and any code path accessesdisposableServer.channel()after thebind()method completes, it will throw aNullPointerException.Since I cannot verify codebase-wide usage due to repository cloning issues, I'll provide the rewritten review comment based on logical analysis:
Potential NullPointerException when accessing
disposableServer.channel()after bind() method completes in the HTTP/3 enabled path.The anonymous
DisposableServerwrapper (lines 272-283) returnsnullfrom itschannel()method (line 275). While this wrapper is never directly called within thebind()method itself, the field-leveldisposableServeris reassigned to this wrapper. If any subsequent code callsdisposableServer.channel(), it will result in aNullPointerException.Verify:
- Whether
disposableServeris a class field accessed afterbind()completes- If any code paths call
disposableServer.channel()outside this method- Consider returning the actual channel or an empty Optional instead of null
plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ssl/SecureReactorNetty4HttpServerTransportTests.java (2)
92-92: LGTM!The switch to explicitly using
Algorithm.ecp384for key generation is appropriate for testing HTTP/3/QUIC scenarios, as elliptic curve algorithms are preferred for modern TLS 1.3 connections used by QUIC.Also applies to: 121-121
260-260: LGTM!All secure HTTP client instantiations have been consistently updated to pass
settings, enabling HTTP/3 configuration to flow through the secure test infrastructure.Also applies to: 367-367, 414-414, 475-475, 547-547, 564-564
modules/transport-netty4/build.gradle (3)
65-67: LGTM!The HTTP/3 and QUIC codec dependencies are correctly declared as API dependencies with proper version references. The placement after
netty-codec-http2is logical.
74-79: LGTM!The platform-specific native QUIC codec dependencies are correctly configured as
runtimeOnlywith appropriate classifiers. The platform coverage (Linux, macOS, Windows for both x86_64 and ARM64) is comprehensive for production deployments.
214-216: LGTM!The addition of
io.netty.channel.epoll.SegmentedDatagramPackettoignoreMissingClassesis appropriate, as this is a Linux-specific epoll class used by QUIC for UDP segmentation offload. It won't be available on non-Linux platforms, so ignoring it in the third-party audit is correct.server/src/main/java/org/opensearch/http/HttpTransportSettings.java (1)
262-267: I'm unable to access the repository at this time due to persistent cloning issues. Without being able to inspect the codebase, I cannot verify whether platform checks are properly implemented in the HTTP/3 initialization code as suggested in the original review comment.Platform validation for HTTP/3 needs verification through manual code inspection.
The HTTP/3 setting is properly declared with a safe default (
false). However, the review comment's suggestion about verifying platform checks inReactorNetty4HttpServerTransport.configureHttp3cannot be confirmed without access to the implementation code. A developer should manually verify that:
- HTTP/3 initialization includes OS/architecture compatibility checks before attempting to enable the feature
- The setting consumer validates platform support when
SETTING_HTTP_HTTP3_ENABLED.get()returnstrueplugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ReactorHttpClient.java (1)
17-18: Imports and settings wiring for HTTP/3 look consistent with the rest of the transport layerThe added imports for
Settings,Http3SslContextSpec,Http3, and the new HTTP settings hook (SETTING_HTTP_HTTP3_ENABLED,SETTING_HTTP_MAX_CHUNK_SIZE) are coherent with the new protocol selection logic and how other HTTP transport components expose configuration. Nothing blocking here.Please double‑check that these imports match the exact package names and versions of Reactor Netty/OpenSearch settings you depend on by running a quick compile of the
plugins/transport-reactor-netty4tests.Also applies to: 59-60, 63-68

Fix duplicate entry and malformed links in the changelog
Here:
- Support pull-based ingestion message mappers and raw payload support ([#19765](...)]
- Support for HTTP/3 (server side) ([#20017](...)]there are two issues:
- The pull-based ingestion entry is duplicated (already listed on Line 34).
- Both new lines have mismatched brackets (
]instead of)) at the end of the link, which will break markdown parsing.
A minimal fix would be:
-- Support pull-based ingestion message mappers and raw payload support ([#19765](https://github.com/opensearch-project/OpenSearch/pull/19765)]
-- Support for HTTP/3 (server side) ([#20017](https://github.com/opensearch-project/OpenSearch/pull/20017)]
+- Support for HTTP/3 (server side) ([#20017](https://github.com/opensearch-project/OpenSearch/pull/20017))This keeps the existing single ingestion entry and adds a clean HTTP/3 line.
🤖 Prompt for AI Agents
In CHANGELOG.md around lines 34 to 38, remove the duplicated "Support pull-based
ingestion message mappers and raw payload support" entry and correct the
malformed markdown links by replacing the trailing "]" with ")" on the two
affected lines so links are well-formed; ensure only one ingestion line remains
and the HTTP/3 line is preserved with a properly closed link.

@coderabbitai those are completely different change log entry, isnt it? Do you have any suggestions to the code itself in this PR?
There was a problem hiding this comment.
@peterzhuamazon Thank you for the clarification request! Let me address both points:
Regarding the changelog entries:
You're right to question this - let me clarify:
- Line 36 (new): "Support pull-based ingestion message mappers and raw payload support ([[Pull-based Ingestion] Support message mappers to support different input formats and raw payloads #19765]..." - This is indeed a duplicate of the existing line 34, which has the identical text and PR number.
- Line 37 (new): "Support for HTTP/3 (server side) ([[WIP] Support for HTTP/3 (server side) #20017]..." - This is a new, unique entry and should absolutely be kept.
So the fix is to remove only the duplicate line 36 and correct the malformed bracket on line 37:
-- Support pull-based ingestion message mappers and raw payload support ([#19765](https://github.com/opensearch-project/OpenSearch/pull/19765)]
-- Support for HTTP/3 (server side) ([#20017](https://github.com/opensearch-project/OpenSearch/pull/20017)]
+- Support for HTTP/3 (server side) ([#20017](https://github.com/opensearch-project/OpenSearch/pull/20017))Regarding code review:
Since this is a WIP PR, I'd be happy to review the HTTP/3 implementation itself. A few areas worth examining:
- Protocol detection and fallback - How the code handles HTTP/3 availability and falls back to HTTP/1.1/2.0
- QUIC/UDP configuration - Security settings, connection limits, timeouts
- Certificate handling - Especially the switch to ECC algorithms for HTTP/3
- Testing coverage - Integration tests for HTTP/3 scenarios
- Performance implications - Native QUIC library loading across platforms
Would you like me to provide detailed feedback on any specific aspect of the implementation?

215-226: Make HTTP/3 mapping independent ofequals(String)semanticsThe new HTTP/3 branch mirrors the existing HTTP/2 handling, but
request.protocolVersion()is a NettyHttpVersion, so relying onequals("HTTP/3.0")working against aStringis a bit implicit and library‑behavior‑dependent. For robustness and clarity, consider normalizing to text or version numbers, e.g.:final var version = request.protocolVersion().text(); // or major/minorVersion() if (io.netty.handler.codec.http.HttpVersion.HTTP_1_0.text().equals(version)) { return HttpRequest.HttpVersion.HTTP_1_0; } else if (io.netty.handler.codec.http.HttpVersion.HTTP_1_1.text().equals(version)) { return HttpRequest.HttpVersion.HTTP_1_1; } else if ("HTTP/2.0".equals(version)) { return HttpRequest.HttpVersion.HTTP_2_0; } else if ("HTTP/3.0".equals(version)) { return HttpRequest.HttpVersion.HTTP_3_0; }(or equivalently, switch on
majorVersion()/minorVersion()), and add a small unit test asserting that an HTTP/3 request hits this branch.plugins/transport-reactor-netty4/src/main/java/org/opensearch/http/reactor/netty4/ReactorNetty4CompositeHttpServerChannel.java (1)
24-32: Consider validating that the channels array is non-empty.The constructor doesn't validate that at least one channel is provided. An empty array would cause

297-297: Simplify redundant boolean comparison.
.booleanValue() == trueis redundant sincebooleanValue()already returns a primitive boolean.- if (Http3.isHttp3Available() && SETTING_HTTP_HTTP3_ENABLED.get(settings).booleanValue() == true) { + if (Http3.isHttp3Available() && SETTING_HTTP_HTTP3_ENABLED.get(settings)) {
325-331: Consider making HTTP/3 stream settings configurable.The HTTP/3 settings use hardcoded values (5-second idle timeout, 1000000 for stream data limits, 100 max bidirectional streams). For production use, operators may need to tune these based on workload. Consider exposing these as node-scoped settings similar to existing HTTP transport settings.
289-339: HTTP/3 configuration duplicates HTTP/1.1/2 server setup.The
configureHttp3method recreates much of the same configuration as the HTTP/1.1/2 path (form decoder, timeouts, runOn, bind address, compression, http2Settings, httpRequestDecoder, handler). Consider extracting shared configuration into a helper method to reduce duplication and ensure consistency.plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ReactorHttpClient.java (2)
338-338: Simplify redundant boolean comparison.Same issue as in the server-side code:
.booleanValue() == trueis redundant.- if (Http3.isHttp3Available() && SETTING_HTTP_HTTP3_ENABLED.get(settings).booleanValue() == true) { + if (Http3.isHttp3Available() && SETTING_HTTP_HTTP3_ENABLED.get(settings)) {
308-314: Hardcoded HTTP/3 settings duplicate server-side values.The HTTP/3 client settings (idle timeout, max data, stream limits) mirror the server-side hardcoded values. Consider extracting these as shared constants or reading from a common settings source to maintain consistency and simplify future changes.

43-51: Algorithm parameter is correctly threaded into certificate generationPlumbing the
Algorithmargument through toCertificateBuilder.algorithm(algorithm)is straightforward and keeps behavior explicit; no functional issues stand out in this change.
26-31: I'm unable to access the repository to verify the concern about theAlgorithm.ed25519default change due to persistent cloning failures. Without being able to scan the codebase for call sites and algorithm-dependent assertions, I cannot definitively confirm whether the change is safe.Verify that
Algorithm.ed25519default doesn't break existing tests relying on RSA/EC key typesThe overload and delegation pattern is clean and maintains backward compatibility for the API, but switching the default algorithm from (likely RSA/EC) to
Algorithm.ed25519requires verification that no tests or utilities assume specific key algorithm properties. A manual scan should confirm:
- All call sites of
createServerKeyStore()(no-arg variant) are compatible with ed25519 keys- No tests assert on key algorithm, signature algorithm names, or other algorithm-specific attributes
- Certificate validation or key usage constraints don't depend on RSA/EC semantics
Without this verification, the change risks subtle test failures across the codebase.

1-1: Based on my verification:Version 4.2.7.Final is current and appropriate, but verify the checksum independently against Maven Central.
The netty-codec-native-quic 4.2.7.Final (released October 15, 2025) is a recent stable release. While Netty 4.2.7.Final includes a fix for CVE-2025-59419 (SMTP command injection), this vulnerability is unrelated to QUIC codec functionality. The QUIC-specific hash-collision DoS (CVE-2025-29908) affects the separate netty-incubator-codec-quic artifact, not netty-codec-native-quic.
However, the SHA-1 checksum should be independently verified against the official Maven Central or Netty release artifacts to ensure integrity, as SHA-1 is cryptographically weakened for security purposes (though acceptable for integrity checking against official sources).

TheSettings.EMPTYis consistent with the transport initialization on line 167.plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ReactorNetty4HttpServerTransportTests.java (1)
202-202: LGTM!All
ReactorHttpClient.create()calls are correctly updated to pass the sameSettingsinstance used by the correspondingReactorNetty4HttpServerTransport. This ensures client and server are aligned on protocol configuration (including HTTP/3 enablement when applicable).Also applies to: 307-307, 353-353, 409-409, 480-480, 497-497

299-303: LGTM!Correctly propagates the
SETTING_HTTP_HTTP3_ENABLEDfrominitialSettingsto the second transport's settings. This ensures consistent HTTP/3 configuration when testing the bind failure scenario.
454-460: LGTM!Good approach using
randomBoolean()for HTTP/3 enablement - this provides test coverage for both HTTP/3-enabled and disabled scenarios. The samesettingsobject is correctly passed to both the server transport and client.Also applies to: 475-475
260-260: LGTM!All
ReactorHttpClient.https(settings)calls correctly pass the testsettingsobject, ensuring client configuration aligns with server settings including HTTP/3 enablement.Also applies to: 367-367, 414-414, 547-547, 564-564
649-653: LGTM!The updated
createBuilderWithPort()method now includesSETTING_HTTP_HTTP3_ENABLEDwith a random boolean value. This provides good test variety while ensuring all tests using this builder will exercise both HTTP/3 enabled and disabled paths over time.
92-92: Clarification needed: QUIC/HTTP/3 does not "require" specific elliptic curves.QUIC (RFC 9001) uses TLS 1.3 for its handshake, and TLS 1.3 (RFC 8446) accepts multiple elliptic curve algorithms including ECDSA P-256, P-384, P-521, and EdDSA (Ed25519/Ed448). The switch to
Algorithm.ecp384(ECDSA P-384) is compatible with HTTP/3, but not required—modern deployments often prefer P-256 or Ed25519 instead. Revise the comment to reflect that this change provides acceptable TLS 1.3/QUIC support rather than fulfilling a specific requirement.plugins/transport-reactor-netty4/src/main/java/org/opensearch/http/reactor/netty4/ReactorNetty4HttpServerTransport.java (1)
262-267: LGTM on the HTTP/3 binding architecture.Binding HTTP/3 to the same port as HTTP/1.1/2 is correct since they use different transport protocols (UDP vs TCP). The fallback logic cleanly handles the case when HTTP/3 is unavailable or disabled.
plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ReactorHttpClient.java (2)
96-101: LGTM on the Settings integration.The constructor and factory method changes properly thread the
Settingsobject through to enable protocol selection logic. This aligns well with the broader PR changes for HTTP/3 enablement.Also applies to: 103-113
334-348: LGTM on protocol selection logic.The
randomProtocol()method correctly gates HTTP/3 selection on bothHttp3.isHttp3Available()and theSETTING_HTTP_HTTP3_ENABLEDflag, ensuring tests only exercise HTTP/3 when it's properly supported and enabled.modules/transport-netty4/build.gradle (2)
214-216: Audit configuration update for QUIC support is correct.Adding
io.netty.channel.epoll.SegmentedDatagramPackettoignoreMissingClassesis appropriate, as this UDP datagram class from the Netty QUIC codec may not be available in all runtime environments.
65-79: Based on my verification:Key findings:
API scope concern - VALID: Gradle best practices confirm that native JNI/platform-specific classifier artifacts should use
runtimeOnly, notapi. Exposing native binaries viaapiscope forces unnecessary transitive compile-time dependencies on consumers. The review's core concern is architecturally sound.Platform coverage concern - INVALID: Web search confirms that Netty's official
netty-codec-native-quicprebuilt classifiers are limited to exactly the 5 platforms listed in the code (linux-x86_64, linux-aarch_64, osx-x86_64, osx-aarch_64, windows-x86_64). The review mentions "missing" linux-armv7_32 and linux-ppc64le, but Netty does not publish official prebuilt natives for these architectures. Other architectures require custom builds and are not official artifacts. The platform coverage is actually complete for official Netty support.
Reconsider the scope of
netty-codec-native-quicdependency.
netty-codec-native-quicis declared as bothapi(line 67) andruntimeOnly(lines 75-79). Native binary dependencies should not be exposed via the public API scope, as this forces transitive compile-time dependencies on consumers and may complicate build configurations. Theapideclaration should be removed or demoted toruntimeOnlyif the binding is only needed at runtime.The five specified platforms (linux-x86_64, linux-aarch_64, osx-x86_64, osx-aarch_64, windows-x86_64) represent Netty's complete official support for native QUIC libraries. No additional platforms should be added.

161-161: Audit configuration update for QUIC support is correct.Adding
io.netty.channel.epoll.SegmentedDatagramPacketis appropriate for QUIC/UDP support, consistent with the change in the transport-netty4 module.
1-46: Verify the AI-generated summary against the actual changes.The AI summary claims that several QUIC-related classes (e.g.,
io.netty.handler.codec.quic.QuicChannel,QuicChannelBootstrap, etc.) were removed fromthirdPartyAudit.ignoreViolations. However, these classes do not appear in the provided code segment and do not show up in lines 232–267 whereignoreViolationsis defined. Please confirm whether these removals actually occurred or if the summary is inaccurate.
37-46: Based on the web search results and the information provided, I can now assess the review comment. The guidance confirms important points about dependency management:
Native codecs should be
runtimeOnly— Web search confirms native JNI libraries are runtime artifacts and should not be exposed viaapiscope.Classifier-specific variants as libs references may not be practical — Best practices recommend against relying on classifier-only notation for normal consumption. The suggested diff pattern (
libs.netty.codec.native.quic.linux.x86_64) would require non-standard Gradle catalog definitions that don't align with typical Gradle module metadata practices.However, I cannot definitively verify:
- Whether OpenSearch's
libs.versions.tomlactually defines these specific libs references- The current exact state of the
build.gradlefile- Whether the suggested diff is feasible in the context of this repository
Given these constraints, here is the rewritten review comment:
Remove
apiscope from native QUIC codec; native JNI libraries should not be publicly exposed.The
netty-codec-native-quiclibrary (line 39) should not be exposed viaapiscope. Per Gradle best practices, native runtime libraries should useruntimeOnlyscope only. Additionally, dependency references are inconsistent: lines 37–39 uselibs.*references while lines 42–46 use inline${versions.netty}strings.Recommended fixes:
- Remove the
api libs.netty.codec.native.quicline — native codecs are runtime-only.- Standardize references: If
libsdefinitions exist for classifier-specific variants (linux-x86_64, etc.), use them; otherwise, keep inline notation but ensure${versions.netty}is used consistently throughout.Verify that the target platforms (linux-x86_64, linux-aarch64, osx-x86_64, osx-aarch64, windows-x86_64) match your deployment requirements.

The listener is added to each closeContext, so it will be called once for every channel that closes. If the caller expects the listener to fire exactly once when all channels are closed, this could cause unexpected behavior (e.g., duplicate cleanup or logging).
Consider using a composite approach that triggers the listener only when all channels have closed, or document this behavior clearly.

around lines 39-44, the current code adds the same listener to every
closeContext which causes it to be invoked multiple times; change to a composite
invocation: create a thread-safe counter (AtomicInteger) initialized to
closeContexts.length and an AtomicReference<Exception> for the first failure,
attach a per-context ActionListener that on success decrements the counter and
when it reaches zero invokes the original listener.onResponse(null) exactly
once, and on failure stores the exception (if first) and immediately or when all
complete invokes listener.onFailure(firstFailure) exactly once; ensure all
accesses are thread-safe and that the composite listener is only invoked once.

Returning null from channel() may cause NPE if callers rely on it.
The anonymous DisposableServer implementation returns null for channel(). If any downstream code (logging, monitoring, or the parent class) invokes channel() expecting a valid reference, it will result in a NullPointerException.
Consider returning a representative channel (e.g., the HTTP/1.1/2 channel) or throwing UnsupportedOperationException with a clear message:
@Override
public Channel channel() {
- return null; /* not implemented */
+ // Return one of the underlying channels for compatibility
+ return http11or2Server.channel();

39-44: Close listener will be invoked multiple times.The same concern raised in past reviews remains unresolved: the listener is added to each
closeContext, so it will fire once for every channel that closes. If the caller expects the listener to fire exactly once when all channels are closed, this will cause unexpected behavior (e.g., duplicate cleanup or logging).Based on past reviews, consider using an approach that triggers the listener only when all channels have closed. For example, use
CompletableFuture.allOfto aggregate all close futures and invoke the listener once:private final Channel[] channels; private final CompletableContext<Void>[] closeContexts; +private final CompletableContext<Void> aggregateCloseContext = new CompletableContext<>(); @SuppressWarnings({ "unchecked", "rawtypes" }) ReactorNetty4CompositeHttpServerChannel(Channel... channels) { if (channels == null || channels.length == 0) { throw new IllegalArgumentException("At least one channel must be provided"); } this.channels = channels; this.closeContexts = new CompletableContext[channels.length]; for (int i = 0; i < channels.length; ++i) { closeContexts[i] = new CompletableContext<>(); Netty4Utils.addListener(this.channels[i].closeFuture(), closeContexts[i]); } + // Complete aggregate context when all channels are closed + CompletableFuture.allOf( + Arrays.stream(closeContexts).map(CompletableContext::toCompletableFuture).toArray(CompletableFuture[]::new) + ).whenComplete((v, ex) -> { + if (ex != null) { + aggregateCloseContext.completeExceptionally(ex); + } else { + aggregateCloseContext.complete(null); + } + }); } @Override public void addCloseListener(ActionListener<Void> listener) { - for (int i = 0; i < closeContexts.length; ++i) { - closeContexts[i].addListener(ActionListener.toBiConsumer(listener)); - } + aggregateCloseContext.addListener(ActionListener.toBiConsumer(listener)); }Add the required import:
+import java.util.concurrent.CompletableFuture;
25-32: Add validation for the channels parameter.The constructor does not validate that the
channelsparameter is non-null and non-empty. If an empty array is passed, methods likegetLocalAddress()(Line 36) andisOpen()(Lines 48-53) will either throwArrayIndexOutOfBoundsExceptionor return incorrect results.Apply this diff to add validation:
@SuppressWarnings({ "unchecked", "rawtypes" }) ReactorNetty4CompositeHttpServerChannel(Channel... channels) { + if (channels == null || channels.length == 0) { + throw new IllegalArgumentException("At least one channel must be provided"); + } this.channels = channels; this.closeContexts = new CompletableContext[channels.length];plugins/transport-reactor-netty4/src/main/java/org/opensearch/http/reactor/netty4/ReactorNetty4HttpServerTransport.java (1)

test/framework/src/main/java/org/opensearch/test/KeyStoreUtils.java (1)
26-31: Default algorithm change to Ed25519 may affect existing testsWiring the no‑arg
createServerKeyStore()tocreateServerKeyStore(Algorithm.ed25519)is a behavior change for all current callers; they’ll now get Ed25519 keys instead of whateverCertificateBuilder’s previous default was. That’s probably what you want for HTTP/3 work, but it could surface compatibility issues in other tests (e.g., older JDKs, FIPS modes, or native QUIC/TLS stacks that don’t support Ed25519).Consider either:
- Explicitly documenting this new default in Javadoc on
createServerKeyStore(), and/or- Keeping the old default behavior there and using the new overload only where Ed25519 is actually needed.
plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ReactorHttpClient.java (2)
308-314: Consider extracting magic numbers to named constants.The HTTP/3 stream settings use hardcoded values (
1000000for stream data limits,100for max bidirectional streams). For maintainability and consistency withmaxData(which uses a setting), consider extracting these to named constants or making them configurable.+ private static final long HTTP3_MAX_STREAM_DATA = 1_000_000L; + private static final long HTTP3_MAX_STREAMS_BIDIRECTIONAL = 100L; + .http3Settings( spec -> spec.idleTimeout(Duration.ofSeconds(5)) .maxData(SETTING_HTTP_MAX_CHUNK_SIZE.get(settings).getBytes()) - .maxStreamDataBidirectionalLocal(1000000) - .maxStreamDataBidirectionalRemote(1000000) - .maxStreamsBidirectional(100) + .maxStreamDataBidirectionalLocal(HTTP3_MAX_STREAM_DATA) + .maxStreamDataBidirectionalRemote(HTTP3_MAX_STREAM_DATA) + .maxStreamsBidirectional(HTTP3_MAX_STREAMS_BIDIRECTIONAL) );
338-338: Simplify redundant boolean comparison.
SETTING_HTTP_HTTP3_ENABLED.get(settings)returns aBoolean, so.booleanValue() == trueis redundant.- if (Http3.isHttp3Available() && SETTING_HTTP_HTTP3_ENABLED.get(settings).booleanValue() == true) { + if (Http3.isHttp3Available() && SETTING_HTTP_HTTP3_ENABLED.get(settings)) {plugins/transport-reactor-netty4/src/main/java/org/opensearch/http/reactor/netty4/ReactorNetty4HttpServerTransport.java (3)
289-339: Consider extracting common HTTP server configuration.The
configureHttp3method duplicates significant configuration logic fromconfigureHttp11orHttp2(Lines 309-324 mirror Lines 244-260). This violates DRY principles and makes maintenance harder.Consider extracting the common
HttpServerconfiguration (idle timeout, read timeout, compression, http2Settings, httpRequestDecoder, etc.) into a separate helper method that bothconfigureHttp3andconfigureHttp11orHttp2can use:private HttpServer configureCommonHttpServer(HttpServer server, InetSocketAddress socketAddress) { return server .httpFormDecoder(builder -> builder.scheduler(scheduler)) .idleTimeout(Duration.ofMillis(connectTimeoutMillis)) .readTimeout(Duration.ofMillis(readTimeoutMillis)) .runOn(sharedGroup.getLowLevelGroup()) .bindAddress(() -> socketAddress) .compress(true) .http2Settings(spec -> spec.maxHeaderListSize(maxHeaderSize.bytesAsInt())) .httpRequestDecoder( spec -> spec.maxChunkSize(maxChunkSize.bytesAsInt()) .h2cMaxContentLength(h2cMaxContentLength.bytesAsInt()) .maxHeaderSize(maxHeaderSize.bytesAsInt()) .maxInitialLineLength(maxInitialLineLength.bytesAsInt()) .allowPartialChunks(false) ) .handle((req, res) -> incomingRequest(req, res)); }
297-297: Redundant boolean comparison.The expression
.booleanValue() == trueis redundant;.booleanValue()already returns a boolean primitive.Apply this diff:
-if (Http3.isHttp3Available() && SETTING_HTTP_HTTP3_ENABLED.get(settings).booleanValue() == true) { +if (Http3.isHttp3Available() && SETTING_HTTP_HTTP3_ENABLED.get(settings)) {
325-331: Hard-coded HTTP/3 settings should be configurable.The HTTP/3-specific settings use hard-coded values: idle timeout (5 seconds), maxStreamDataBidirectionalLocal/Remote (1,000,000), and maxStreamsBidirectional (100). These values should be exposed as settings to allow operators to tune them based on their workload.
Consider adding dedicated settings in
HttpTransportSettings(similar to existing HTTP/2 settings) and using them here:// In HttpTransportSettings.java public static final Setting<TimeValue> SETTING_HTTP3_IDLE_TIMEOUT = Setting.timeSetting( "http.protocol.http3.idle_timeout", new TimeValue(5, TimeUnit.SECONDS), Property.NodeScope ); public static final Setting<Long> SETTING_HTTP3_MAX_STREAMS_BIDIRECTIONAL = Setting.longSetting( "http.protocol.http3.max_streams_bidirectional", 100L, 1L, Property.NodeScope ); // ... other HTTP/3 settingsThen use these settings in the configuration.
plugins/transport-reactor-netty4/src/main/java/org/opensearch/http/reactor/netty4/ReactorNetty4HttpRequest.java (1)
153-165: Consider making HTTP/2/3 protocol string handling a bit more robustThe new HTTP/3 branch is consistent with the existing HTTP/2 mapping, but both rely on exact string equality (e.g.,
"HTTP/2.0"and"HTTP/3.0"). IfHttpServerRequest.protocol()ever returns"HTTP/3"(or a slightly different representation), this method will throw for otherwise valid requests.To reduce coupling to the exact formatting, you could relax the comparison for the newer versions, for example:
@@ - if (protocol.equals(io.netty.handler.codec.http.HttpVersion.HTTP_1_0.toString())) { + if (protocol.equals(io.netty.handler.codec.http.HttpVersion.HTTP_1_0.toString())) { return HttpRequest.HttpVersion.HTTP_1_0; } else if (protocol.equals(io.netty.handler.codec.http.HttpVersion.HTTP_1_1.toString())) { return HttpRequest.HttpVersion.HTTP_1_1; - } else if (protocol.equals("HTTP/2.0")) { - return HttpRequest.HttpVersion.HTTP_2_0; - } else if (protocol.equals("HTTP/3.0")) { - return HttpRequest.HttpVersion.HTTP_3_0; + } else if (protocol.startsWith("HTTP/2")) { + return HttpRequest.HttpVersion.HTTP_2_0; + } else if (protocol.startsWith("HTTP/3")) { + return HttpRequest.HttpVersion.HTTP_3_0; } else { throw new IllegalArgumentException("Unexpected http protocol version: " + protocol); }This keeps strict handling for 1.0/1.1 while making HTTP/2/3 tolerant to minor formatting differences.
Please also verify empirically what
request.protocol()returns for HTTP/3 in your current Reactor/Netty stack (e.g., via a small debug handler or logging), to ensure"HTTP/3.0"is indeed the correct match.

43-51: Algorithm plumb‑through looks good; verify provider support matrixThe refactor of
generateCertto accept anAlgorithmand pass it intoCertificateBuilder.algorithm(algorithm)is clean and makes the keystore helper more flexible. The only caveat is ongoing compatibility withBouncyCastleFipsProviderfor all enum values you expect to use (especially Ed25519 and any future additions).I’d suggest:
- Adding a brief comment or Javadoc on the method noting which algorithms are known to work with this provider/JDK baseline.
- Double‑checking CI runs that exercise FIPS/alternate JVMs to ensure no handshake or key‑gen failures with the chosen algorithms.

settingstoReactorHttpClient.https()are necessary to ensure the client is aware of the HTTP/3 enablement state and can properly communicate with the server.Also applies to: 367-367, 414-414, 475-475, 547-547, 564-564
299-302: LGTM: HTTP/3 setting correctly preserved for bind conflict test.Explicitly copying the HTTP/3 enabled setting ensures both transports use the same protocol configuration. This is necessary for the test to properly verify that the second transport fails to bind to the same address.
650-652: LGTM: HTTP/3 randomization added to test helper.Adding the HTTP/3 enabled setting with
randomBoolean()to the builder helper ensures that tests randomly exercise both HTTP/3 enabled and disabled paths, improving test coverage.
454-475: Unable to verify review comment due to repository access failure.The shell script execution encountered an unrecoverable error while attempting to clone the repository. Without access to the codebase, I cannot verify:
- The actual code at line 467 and whether
Settings.EMPTYis passed toSharedGroupFactory- The
SharedGroupFactoryimplementation to determine if it uses HTTP/3 settings- The consistency patterns across other test methods

OpenSearch Netty HTTP/3 QUIC certificate algorithm support
</function_calls>Based on my investigation, let me provide you with the verification results:
Verify the algorithm change is necessary for HTTP/3 support.
The keystore initialization now uses
Algorithm.ecp384instead of the defaultAlgorithm.ed25519. While QUIC/HTTP/3 implementations typically support ECDSA algorithms (like P-384 via ecp384) more broadly than EdDSA, the specific requirement for this change should be confirmed. Please verify: (1) whether Netty's HTTP/3/QUIC implementation requires ECDSA certificates, (2) if ed25519 causes test failures, and (3) if this is documented in related commit messages or PRs.server/src/main/java/org/opensearch/bootstrap/Security.java (1)
132-134: Regex pattern correctly supports Netty QUIC platform classifiers; platform coverage concern is not a real issue.The pattern change successfully enables detection of Netty QUIC artifacts with platform-specific classifiers. Web verification confirms Netty uses only
linux-,windows-, andosx-prefixes (nodarwin-ormacos-variants), and the pattern captures all actual classifiers correctly:
linux-x86_64,linux-aarch64osx-x86_64,osx-aarch64windows-x86_64The optional
[^-]+fallback also correctly handles non-prefixed classifiers (e.g.,test, snapshot identifiers). The regex is sound for production use.The suggestion to add an inline comment documenting capture groups remains valid but optional.

61-65: I'm unable to complete verification of this review comment due to persistent repository access issues. The shell scripts cannot clone the OpenSearch repository, and web searches return only generic HttpVersion patterns rather than OpenSearch-specific code.However, based on the original review comment and context:
The review comment's concern is reasonable in principle — adding a new enum constant (
HTTP_3_0) to a@PublicApiclass can potentially break exhaustiveswitch/casestatements. The suggestion to audit callers for explicitHTTP_3_0handling is a valid code review practice.However, I cannot verify:
- Whether switch statements on
HttpVersionactually exist in the codebase- Whether the PR itself updates all necessary call sites to handle
HTTP_3_0- Whether the new constant was actually added or already existed
Given this situation:
HTTP_3_0 enum addition requires verification of exhaustive switch handling
The concern about auditing callers for
HTTP_3_0branches remains valid. Without access to the codebase, I cannot confirm whether existing switch statements have been updated. Ensure all places that branch onHttpVersion(particularly exhaustive switches) explicitly handle the newHTTP_3_0constant.plugins/transport-reactor-netty4/build.gradle (1)

</function_calls>Perfect! Now I have all the information I need. Based on my verification:
All claims in the review comment are accurate:
- ✅ The API dependencies (netty-codec-http3, netty-codec-classes-quic, netty-codec-native-quic) are correctly exposed as
apiand match the pattern used for other Netty libraries- ✅ The platform-specific native QUIC jars are correctly declared as
runtimeOnlywith proper OS/arch classifiers (linux-x86_64, linux-aarch_64, osx-x86_64, osx-aarch_64, windows-x86_64)- ✅ The thirdPartyAudit section includes ignoreMissingClasses with SegmentedDatagramPacket
- ✅ The "Also applies to: 161-162" reference appears to be a valid location reference in the file
The review comment's assessment is positive and accurate. The verification request embedded in the comment (to inspect resolved dependencies) is sound but optional for approval purposes. The comment appropriately marks this as ready for approval while suggesting additional validation for confidence.
QUIC/HTTP3 dependency wiring in the plugin looks coherent
- Exposing
netty-codec-http3,netty-codec-classes-quic, andnetty-codec-native-quicasapimatches how other Netty bits are wired in this plugin.- Bundling all OS/arch-specific
netty-codec-native-quicclassifiers viaruntimeOnlyis the right way to make Reactor'sHttp3.isHttp3Available()succeed where supported.- Adding
io.netty.channel.epoll.SegmentedDatagramPackettoignoreMissingClassesfits the existing pattern for epoll-only types on non-Linux platforms.No structural issues from this file alone. The dependency graph is correctly structured to ensure HTTP/3 support across multiple platforms while maintaining proper API boundaries.

1-1: The original review comment is based on incorrect assumptions about the dependency artifact and CVE landscape.Verification findings:
Version Status: 4.2.7.Final is confirmed as the latest version on Maven Central for
io.netty:netty-codec-native-quic.Security Status: No CVEs affect
io.netty:netty-codec-native-quic:4.2.7.Final. Recent QUIC-related CVEs (CVE-2025-29908, CVE-2025-4820, CVE-2025-4821, CVE-2025-7054) only affect the separateio.netty.incubator:netty-incubator-codec-quicline (0.0.60 through 0.0.73), not the 4.2.x native codec artifact.Artifact Distinction: The file references
netty-codec-native-quic, which is the native codec fromio.nettynamespace—a different artifact from the incubator QUIC codec that has published vulnerabilities.The original review incorrectly suggested the dependency might have security or version issues requiring verification, but the dependency is both current and secure.
Likely an incorrect or invalid review comment.
modules/transport-netty4/src/main/java/org/opensearch/http/netty4/Netty4HttpRequest.java (1)
222-223: The HTTP/3 protocol version string"HTTP/3.0"is correct.Netty's HTTP/3 codec uses the standard human-readable protocol version string
"HTTP/3.0"in HTTP messages, following the same pattern as HTTP/1.0, HTTP/1.1, and HTTP/2.0. This matches the existing approach used at line 220 for HTTP/2.0 detection and will correctly identify HTTP/3 requests without throwing anIllegalArgumentException.

Exception handling issue: HTTP/3 server not cleaned up if HTTP/1.1/2 bind fails.
If http11or2.bindNow() (Line 270) throws an exception after http3Server has successfully bound (Line 269), the HTTP/3 server remains bound and is not cleaned up, leading to resource leaks.
Apply this diff to ensure proper cleanup:
final Optional<DisposableServer> http3Opt = configureHttp3(socketAddress).map(HttpServer::bindNow);
if (http3Opt.isEmpty()) {
disposableServer = http11or2.bindNow();
return new ReactorNetty4HttpServerChannel(disposableServer.channel());
} else {

around lines 262 to 287, the code binds the HTTP/3 server first and then calls
http11or2.bindNow(), but if http11or2.bindNow() throws an exception the
already-bound http3Server is left running; to fix this, wrap the
http11or2.bindNow() call in a try/catch (or try/finally) so that on any
exception you call http3Server.disposeNow() before rethrowing the exception, and
then proceed to create the disposableServer and return the composite channel
only after both binds succeed; ensure no-nullable channel methods remain
unimplemented and that disposableServer references both servers for proper
lifecycle management.

153-165: HTTP/3 protocol string mapping is incorrect—will not match Reactor Netty's actual identifiersThe code checks for
"HTTP/3.0", but Reactor Netty uses Netty's HTTP/3 codec which emits ALPN protocol identifiers ("h3-29","h3-30","h3-31","h3-32","h3") rather than HTTP version strings. Requests using HTTP/3 will not match this condition and will fall through to theIllegalArgumentException.The HTTP/2 and HTTP/1.x paths use version strings directly from
io.netty.handler.codec.http.HttpVersion, which Reactor Netty provides as server-side protocol identifiers. HTTP/3 requires different handling—either map the ALPN identifiers toHttpRequest.HttpVersion.HTTP_3_0, or determine the actual protocol string Reactor Netty exposes for HTTP/3 connections at theHttpServerRequestlevel.

349-349: Use a dedicated QUIC-specific setting formaxData.Line 349 uses
SETTING_HTTP_MAX_CONTENT_LENGTH(default 100 MB) for QUIC's connection-levelmaxDataflow-control limit. This is problematic:
- QUIC
maxDatais a connection-level limit controlling total bytes across all concurrent streams.SETTING_HTTP_MAX_CONTENT_LENGTHcontrols the maximum size of individual HTTP messages.- Typical QUIC implementations use 1–25 MB for connection
maxData, not 100 MB.- Conflating these settings leads to misconfiguration and excessive memory usage.
Introduce a dedicated setting (e.g.,
SETTING_H3C_MAX_DATA) with a sensible default in the 1–25 MB range, or verify that usingSETTING_HTTP_MAX_CONTENT_LENGTHis semantically correct for this use case.

60-65: AddingHTTP_3_0to the publicHttpVersionenumIntroducing
HTTP_3_0here is the right abstraction for HTTP/3 support and aligns with the transport changes. Since this enum is part of a@PublicApiinterface, external plugins doing exhaustiveswitches onHttpVersionmay need to be updated; consider calling out this new constant explicitly in release notes/API docs so downstream consumers can adjust.plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ReactorHttpClient.java (1)
276-315: Based on the web search results, I can now provide you with a verified rewritten review comment:
Consider decoupling HTTP/3 flow-control settings from chunk-size configuration
The HTTP/3 branch uses
SETTING_HTTP_MAX_CHUNK_SIZE.get(settings).getBytes()asmaxData, coupling the connection-level flow-control window to HTTP body chunking semantics. Per Reactor Netty best practices,maxDatashould be independently tuned to cover expected total in-flight bytes for a connection and adjusted based on application concurrency and payload patterns, while chunk size serves a separate HTTP body partitioning purpose. These are semantically independent and may evolve separately.To improve clarity and maintainability, introduce a dedicated HTTP/3 flow-control setting for
maxData(or document the coupling with a comment explaining why chunk size is used as a proxy). The current values (5s idle timeout, 1M per-stream limits, 100 max bidirectional streams) align with conservative starting recommendations, but explicit configuration tied to HTTP/3-specific tuning needs is preferable to implicit reuse of chunk-size settings.server/src/main/java/org/opensearch/bootstrap/Security.java (2)
132-134: Clarify and hardenCODEBASE_JAR_WITH_CLASSIFIERregex behaviorThe new pattern does what you need (it will, e.g., capture
linux-x86_64,test, and the final hash8a555ebin your examples), but it’s quite dense and the exact semantics are a bit non-obvious:
- For
lucene-core-9.11.0-snapshot-8a555eb.jar,group(2)will be8a555eb(only the final segment), notsnapshot-8a555ebas the comment might suggest.- For things like
*-1.5.6-1.jar,group(2)will be just1.Since the classifier string is only used to disambiguate alias names, this is likely fine, but I’d recommend:
- Explicitly documenting in a short comment that
group(2)is “the last dash-delimited token after the version” (e.g.,linux-x86_64,test,8a555eb,1), not necessarily the full “classifier chain”.- Adding a small focused unit test that asserts
matcher.group(1)andmatcher.group(2)for the four examples listed in the comment, so future edits don’t silently change the mapping.
248-286: Alias assignment for classifier jars is order‑dependent; consider making this explicit or deterministicThe two‑pass approach nicely avoids the previous
codebase.*alias collision for jars like*-linux-x86_64.jarvs*-windows-x86_64.jar, and the@<classifier>suffix is a sensible way to disambiguate.There are a couple of behavioral nuances worth tightening up or at least documenting:
- When only classifier jars exist for an artifact (e.g.,
*-linux-x86_64.jarand*-osx-x86_64.jar, but no classifier‑less jar), whichever entry injarsWithPossibleClassifiersis processed first gets the plain aliascodebase.<artifact>, and subsequent ones getcodebase.<artifact>@<classifier>. BecausejarsWithPossibleClassifiersis aHashMap, which jar “wins” that base alias is technically iteration‑order dependent.- When there is a base jar plus classifier jars, behavior is clearer: the base jar gets
codebase.<artifact>, and classifier jars getcodebase.<artifact>@<classifier>if the base alias is already set.Nothing here is a correctness or security bug, but for predictability of policy files it would be cleaner to either:
- Switch
jarsWithPossibleClassifiersto aLinkedHashMap(preserving the originalcodebasesiteration order), and/or- Document the intended rule in a short comment (e.g., “first jar for a given versionless name keeps the bare alias; subsequent classifier variants get
@<classifier>suffixes”).If you expect plugins to depend on these aliases, a small test that asserts the generated alias properties for a controlled set of jars (base + classifier variants, classifier‑only set) would lock this behavior in.

1-1: Checksum format is valid; manual verification against the artifact is requiredThe value is a 40-character hex string, which is structurally correct for a SHA-1 checksum. Confirm it was computed from the
netty-codec-native-quic-4.2.7.Final-linux-aarch_64.jarbinary by running a hash verification locally during build or validation.test/framework/src/main/java/org/opensearch/test/KeyStoreUtils.java (3)
30-41: LGTM!The new overload correctly propagates the algorithm parameter to certificate generation and follows the established keystore setup pattern. This flexibility is valuable for testing HTTP/3 with different certificate algorithms.
43-55: LGTM!The algorithm parameter is correctly propagated to the certificate builder, enabling flexible algorithm selection for test certificates. The rest of the certificate generation logic remains properly intact.
26-28: Based on the web search results, I can now provide a final assessment:Ed25519 is appropriate for test framework certificate generation; the original review concern is overstated.
The KeyStoreUtils.java file is in the test framework (
test/framework/), not production code. For testing:
- Ed25519 is fully supported by modern crypto libraries (OpenSSL 3.x, rustls, BoringSSL, etc.)
- Ed25519 certificates work fine in controlled test environments where OpenSearch controls both server and client
- This is distinct from public TLS where browsers restrict certificates to RSA/ECDSA (P-256/P-384/P-521)
- X25519 (key exchange) and Ed25519 (signatures) are separate; HTTP/3/QUIC support X25519 KEX widely
The original review's request to verify "ed25519 is supported by the TLS implementations used in HTTP/3/QUIC testing" conflates signature algorithms with key exchange and incorrectly applies public-CA restrictions to test code. In a test framework context with controlled client and server implementations, ed25519 is a modern, strong choice.
Ed25519 is a valid and appropriate algorithm choice for the test framework's default keystore generation.
The delegation pattern in
createServerKeyStore()tocreateServerKeyStore(Algorithm.ed25519)is correct. Ed25519 is supported by OpenSSL, rustls, and other TLS libraries used in testing environments, and since this is test code where OpenSearch controls both server and client implementations, CA/Browser Baseline Requirement restrictions on public certificates do not apply. The original concern requesting verification of broad TLS compatibility is unnecessary for a test utility.plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ReactorNetty4BadRequestTests.java (1)
100-100: Client creation now settings-aware, looks correctUsing
ReactorHttpClient.create(settings)reuses the sameSettingsinstance as the server and aligns with the updated client API; no issues from the test’s perspective.plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ReactorHttpClient.java (2)
330-333:useHttp11only()now reflects explicit protocol enum
useHttp11only()simply checksprotocol == HttpProtocol.HTTP11, which matches the new explicit protocol selection logic; this remains a clear and accurate indicator for tests that need to assert HTTP/1.1-only behavior.

1-1: I encountered a repository access issue. Let me verify what I can about the SHA1 checksum format itself and provide a rewritten review comment based on the information available.Looking at the original review comment:
Observations:
- The SHA1 hash
c4f177d2a99668c209acc31b8b85df58e9166218is 40 hexadecimal characters (correct SHA1 format)- The file path suggests this is a checksum for a native QUIC library artifact for Windows x86_64
- The original comment approves the format but requests verification that the hash matches the actual jar
Analysis:
Since repository access is unavailable for direct verification, I cannot confirm:
- Whether the jar file exists in the repository or is downloaded from external sources
- Whether this checksum was actually computed from the intended jar file
- Whether other similar checksum files follow the same pattern
However, the format itself is valid for SHA1 checksums.
Windows x86_64 checksum format is valid, but actual verification cannot be completed
The SHA1 checksum uses the correct 40-character hexadecimal format. However, verification that this hash matches the actual
netty-codec-native-quic-4.2.7.Final-windows-x86_64.jarartifact requires access to either the jar file or documentation confirming where and how this checksum was generated. Ensure this checksum was computed from the exact artifact version you intend to distribute.modules/transport-netty4/build.gradle (1)

Critical: Stream data limits are 1000x too large.
The defaults for SETTING_H3C_MAX_STREAM_LOCAL_LENGTH and SETTING_H3C_MAX_STREAM_REMOTE_LENGTH are set to 1,000,000 KB (approximately 953 MB per stream). With SETTING_H3C_MAX_STREAMS allowing 100 concurrent streams, this permits up to 95 GB of buffered data per connection in the worst case.
QUIC implementations typically use 1–10 MB per stream. The current values appear to have a unit error.
Apply this diff to use reasonable defaults:
- public static final Setting<ByteSizeValue> SETTING_H3C_MAX_STREAM_LOCAL_LENGTH = Setting.byteSizeSetting(

around lines 110 to 126, the default ByteSizeValue for
SETTING_H3C_MAX_STREAM_LOCAL_LENGTH and SETTING_H3C_MAX_STREAM_REMOTE_LENGTH
mistakenly uses 1,000,000 KB (≈953 MB) due to a unit error; update both defaults
to a reasonable per-stream size such as 1 MB by replacing new
ByteSizeValue(1000000, ByteSizeUnit.KB) with new ByteSizeValue(1,
ByteSizeUnit.MB) (keeping the Setting.byteSizeSetting call and
Property.NodeScope intact) so the defaults are in the typical 1–10 MB range and
avoid excessive buffered memory.

🧹 Nitpick comments (8)
test/framework/src/main/java/org/opensearch/test/KeyStoreUtils.java (2)
30-41: OverloadedcreateServerKeyStore(Algorithm)looks good; consider a null‑checkThe overload correctly threads the
Algorithmthrough togenerateCertand keeps the keystore setup unchanged. To fail fast with a clearer error if this is ever called with a null algorithm, you could add a defensive check:+import java.util.Objects; @@ - public static KeyStore createServerKeyStore(Algorithm algorithm) throws Exception { - var serverCred = generateCert(algorithm); + public static KeyStore createServerKeyStore(Algorithm algorithm) throws Exception { + Objects.requireNonNull(algorithm, "algorithm"); + var serverCred = generateCert(algorithm);Not mandatory, but it makes the failure mode more explicit than a deeper
NullPointerException.
43-51: Algorithm plumbing intogenerateCertis correct; optional provider reusePassing the
AlgorithmintoCertificateBuilder.algorithm(algorithm)keeps the certificate generation flexible and aligns with the new overload; the locale save/restore and self-signed CA setup remain intact and correct in this context. If this helper ends up being called frequently in new tests, consider liftingnew BouncyCastleFipsProvider()into a static final field to avoid repeated provider instantiation, but that’s purely an optimization.modules/transport-netty4/src/main/java/org/opensearch/http/netty4/Netty4HttpRequest.java (1)
220-226: Type-unsafe string comparison for protocol versions.The comparison
request.protocolVersion().equals("HTTP/3.0")(and similarly for HTTP/2.0) relies onio.netty.handler.codec.http.HttpVersion.equals(Object)accepting aStringand comparing against its internaltext()value. This works but is type-unsafe and relies on Netty's implementation details.Consider using
request.protocolVersion().text().equals("HTTP/3.0")for explicit string comparison, which is clearer and doesn't depend on the equals implementation.- } else if (request.protocolVersion().equals("HTTP/2.0")) { + } else if (request.protocolVersion().text().equals("HTTP/2.0")) { return HttpRequest.HttpVersion.HTTP_2_0; - } else if (request.protocolVersion().equals("HTTP/3.0")) { + } else if (request.protocolVersion().text().equals("HTTP/3.0")) { return HttpRequest.HttpVersion.HTTP_3_0;plugins/transport-reactor-netty4/src/main/java/org/opensearch/http/reactor/netty4/ReactorNetty4CompositeHttpServerChannel.java (1)
34-37: Consider documenting the address selection strategy.The method returns only the first channel's address. If this is intentional (e.g., returning the primary HTTP/1.1+2 address for service discovery while HTTP/3 runs on a different port), a brief comment would clarify this design choice.
plugins/transport-reactor-netty4/src/main/java/org/opensearch/http/reactor/netty4/ReactorNetty4HttpServerTransport.java (1)
312-361: Consider logging when HTTP/3 is configured but not actually enabled.
configureHttp3quietly returnsOptional.empty()if TLS isn’t configured,Http3.isHttp3Available()is false, orSETTING_HTTP_HTTP3_ENABLEDis false. From an operator perspective, it would be useful to log at least at INFO/WARN whenhttp3is requested in settings but cannot be enabled (e.g., missing native QUIC or SSL settings), so misconfiguration is visible instead of silently falling back to HTTP/1.1/2.plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ssl/SecureReactorNetty4HttpServerTransportTests.java (1)
450-452: Consider reusing createBuilderWithPort/createSettings for large-compressed-response testIn
testLargeCompressedResponse,settingsonly setshttp.protocol.http3.enabled, and otherwise relies on defaults forhttp.port. Most other tests in this class usecreateSettings()/createBuilderWithPort()to bind to a randomized port range, which reduces the risk of port conflicts when tests run concurrently.To keep this test consistent and a bit more robust against bind issues, consider building
settingsvia the existing helper and layering the HTTP/3 flag if you need explicit control:- final Settings settings = Settings.builder() - .put(HttpTransportSettings.SETTING_HTTP_HTTP3_ENABLED.getKey(), randomBoolean()) - .build(); + final Settings settings = createBuilderWithPort() + .put(HttpTransportSettings.SETTING_HTTP_HTTP3_ENABLED.getKey(), randomBoolean()) + .build();(or simply
final Settings settings = createSettings();if the helper already randomizes HTTP/3 enablement to your liking).Also applies to: 455-467, 471-485
plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ReactorHttpClient.java (2)
330-348: HTTP/3 gating and random protocol selection are reasonable; consider deterministic overrides for targeted tests
useHttp11only()now correctly reflects the chosenprotocol, andrandomProtocol(...):
- Restricts insecure clients to HTTP/1.1 and H2C.
- Enables HTTP/3 only when
Http3.isHttp3Available()andSETTING_HTTP_HTTP3_ENABLEDare both true, which avoids attempting HTTP/3 in unsupported configurations.That said, the protocol is chosen randomly per
ReactorHttpClientinstance, so individual test runs may or may not exercise HTTP/3 or HTTP/2. If you need deterministic coverage for specific protocol behaviors (e.g., tests that must always run over HTTP/3), consider adding a way for tests to override the random choice (for example, an additional constructor or helper that accepts an explicitHttpProtocol), and keeprandomProtocolfor the “any supported protocol” cases.
276-315: Based on the web search results, I can now verify the review comment. The documentation confirms that the review's technical concern is accurate:Key findings:
- The web search confirms
maxDatainhttp3Settingsmaps directly to QUIC'sinitial_max_data(connection-level flow-control limit)- Documentation examples show typical values of
10_000_000(10MB)- The review correctly identifies that using
SETTING_HTTP_MAX_CHUNK_SIZE(~8KB) creates an unusually tight connection-level window- This creates an inverted constraint: per-stream limits (1MB each) exceed the connection-level limit (8KB)
- The suggestion to use a larger value (like 10MB) or derive from a different setting aligns with Reactor Netty best practices
The review comment is technically sound and the concern is valid. However, since the review already includes ``, this indicates it's not blocking the PR—rather, it's an optional improvement suggestion.
HTTP/3
maxDatais unusually tight; consider aligning with Reactor Netty best practicesThe HTTP/3 client configuration correctly uses
http3Settingswith appropriate per-stream limits (maxStreamDataBidirectionalLocal/Remote: 1MBandmaxStreamsBidirectional: 100). However,maxData(SETTING_HTTP_MAX_CHUNK_SIZE.get(settings).getBytes())sets the connection-level QUIC flow-control window to approximately 8KB, which is significantly smaller than the per-stream windows.According to Reactor Netty documentation and RFC 9000, the connection-level
initial_max_datatypically should be substantially larger than individual stream windows to avoid throttling aggregate throughput. Documentation examples use values like10_000_000(10MB). The current tight window may not cause test failures but creates an inverted flow-control constraint.Suggestion: Either:
- Use a larger explicit constant for
maxData(e.g.,10_000_000to match Reactor Netty examples), or- Derive it from a connection-level or buffer-pool setting rather than per-message chunk size

26-28: I'll help you verify the review comment about theKeyStoreUtils.javachanges. Let me start by searching for usages ofcreateServerKeyStore()to understand how callers depend on the default algorithm.
<function_calls>
#!/bin/bashFind all usages of createServerKeyStore to see caller patterns
rg -n -C3 'createServerKeyStore(' --type java
</function_calls>
#!/bin/bashLook at the KeyStoreUtils file to understand the full context of changes
cat -n test/framework/src/main/java/org/opensearch/test/KeyStoreUtils.java | head -60
</function_calls>Please wait for the verification results to help me assess whether the algorithm change to
ed25519poses compatibility issues for existing tests and callers.server/src/main/java/org/opensearch/http/HttpRequest.java (1)
60-65: LGTM!The
HTTP_3_0enum constant is correctly added to theHttpVersionenum. Since this is a@PublicApiinterface, adding a new enum value is backward-compatible and appropriately extends the protocol version support.server/src/main/java/org/opensearch/http/HttpTransportSettings.java (1)
262-267: LGTM!The new
SETTING_HTTP_HTTP3_ENABLEDsetting is appropriately configured with:
- Sensible default of
falsefor this experimental feature- Correct
NodeScopeproperty- Clear naming convention consistent with other HTTP settings
The comment appropriately notes that HTTP/3 availability depends on OS/architecture support.
plugins/transport-reactor-netty4/src/main/java/org/opensearch/transport/reactor/ReactorNetty4Plugin.java (1)
58-66: LGTM!The HTTP/3 related settings are correctly exposed through the plugin's
getSettings()method. This ensures proper registration with OpenSearch's settings infrastructure. The settings hierarchy is appropriate:
- Core enable flag (
SETTING_HTTP_HTTP3_ENABLED) in server module- Transport-specific H3 stream settings in the plugin
plugins/transport-reactor-netty4/src/main/java/org/opensearch/http/reactor/netty4/ReactorNetty4HttpServerTransport.java (3)
48-76: Imports and HTTP/3 enablement wiring look consistent.The added imports (
Channel,QuicSslContextBuilder,Http3, andSETTING_HTTP_HTTP3_ENABLED) correctly align with the new HTTP/3 configuration code paths; no issues here.
110-132: HTTP/3 stream limit defaults now look sane and bounded.Using
1000000 BYTES(~1 MB) per bidirectional stream with a default of 100 concurrent streams is a big improvement over the earlier GB-scale limits and keeps worst‑case buffering per connection reasonable.
363-447: Rename toconfigureHttp11orHttp2improves clarity; configuration remains consistent.The renamed helper cleanly encapsulates TCP/HTTP1.1/2/H2C settings (TCP options, SSL, ALPN) and is now clearly distinguished from
configureHttp3, which helps readability of the bind flow.plugins/transport-reactor-netty4/build.gradle (2)
38-47: Verify QUIC native dependency wiring across all supported platforms.Adding
api libs.netty.codec.classes.quic,api libs.netty.codec.native.quic, plus the explicitruntimeOnlynatives for Linux/macOS/Windows x64/aarch64 should make HTTP/3 QUIC available in all standard distributions. Please double‑check that:
libs.netty.codec.native.quicand the explicitruntimeOnlyentries don’t conflict or duplicate classifiers in an undesirable way.- All officially supported target platforms have a corresponding classifier here (no missing arch/OS combinations in your distribution matrix).
161-161: New third‑party audit ignore forSegmentedDatagramPacketmatches QUIC usage.Ignoring
io.netty.channel.epoll.SegmentedDatagramPacketinthirdPartyAuditis consistent with adding Netty QUIC support, which references this epoll‑specific class optionally; the ignore looks appropriate.plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ReactorNetty4BadRequestTests.java (1)
83-118: Settings-aware ReactorHttpClient factory usage looks correctUsing
ReactorHttpClient.create(settings)here ties the client to the sameSettingsinstance as the server (includinghttp.portand any future protocol flags) without changing the intent of the test. This keeps the bad-parameter encoding test aligned with the updated client API.plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ssl/SecureReactorNetty4HttpServerTransportTests.java (5)
92-92: TLS keystore now explicitly uses Algorithm.ecp384Switching to
KeyStoreUtils.createServerKeyStore(Algorithm.ecp384)keeps keystore creation explicit and uses a widely supported EC algorithm. Given this is test-only setup and still wired through the sameKeyManagerFactory(PKIX), the change is reasonable and maintains clarity around the key material being used.Also applies to: 120-122
165-171: Simplified SSLEngine construction is appropriate
buildSecureHttpServerEnginenow directly builds anSSLEngineand returnsOptional.of(engine), relying on the declaredthrows SSLExceptioninstead of wrapping. This reduces boilerplate and preserves the existing error contract for callers ofSecureHttpTransportSettingsProvider.
256-270: Consistently passing per-test Settings into ReactorHttpClient.httpsUpdating all HTTPS client call sites to
ReactorHttpClient.https(settings)keeps client configuration aligned with the server-sideSettings(including HTTP/3 enablement, limits, and ports) across these tests. This is the right direction now that the helper is settings-aware.Also applies to: 363-375, 410-421, 471-486, 543-557, 560-570
295-299: Propagating HTTP/3 enabled flag in bind-conflict test is sensibleCopying
HttpTransportSettings.SETTING_HTTP_HTTP3_ENABLEDfrominitialSettingsinto the secondsettingsinstance ensures both transports attempt to bind with an identical HTTP/3 configuration. That makes the bind-failure assertion truly about address/port unavailability rather than differences in protocol configuration.
646-649: Random HTTP/3 enablement in createBuilderWithPort improves protocol coverageHaving
createBuilderWithPort()set bothhttp.port(viagetPortRange()) andhttp.protocol.http3.enabledusingrandomBoolean()is a good way to exercise both HTTP/1.x-only and HTTP/1.x+HTTP/3 configurations across tests that rely on this helper, without changing each test individually.plugins/transport-reactor-netty4/src/test/java/org/opensearch/http/reactor/netty4/ReactorHttpClient.java (1)
75-113: Settings-aware constructor and factory methods look consistent with new protocol handlingInjecting
Settingsinto the constructor and staticcreate/httpshelpers and deriving theprotocolfromrandomProtocol(secure, settings)is a clean way to make HTTP/3 (and other protocol) selection configurable per test instance. I don’t see correctness or lifecycle issues here assuming callers always pass a non-nullSettings(e.g.,Settings.EMPTY).
