From 0eece87d98721ae162465b47e0a7424fdf78586c Mon Sep 17 00:00:00 2001 From: Barbatos Date: Thu, 13 Aug 2026 11:29:21 +0800 Subject: [PATCH 01/21] chore(p2p): add libp2p v2.2.9 source as p2p module Vendors tronprotocol/libp2p tag v2.2.9 (c564f263d310d7a964035d3b597634aba6bda86d) into a local `p2p` Gradle module, ahead of switching `common` off the external io.github.tronprotocol:libp2p Maven artifact. The source in this commit is byte-identical to `git archive v2.2.9 src/main`, so a reviewer can diff it directly against the upstream tag and confirm nothing was altered on the way in. Everything we change about it lands in the next commit, separately and for exactly that reason. Two arrangements differ from the upstream layout: - The example code moves out of src/main into its own `example` sourceSet. It still compiles, so an API change in main surfaces here too, but it is not packaged into p2p.jar and is not run as tests. - Generated protobuf sources are gitignored and rebuilt by :p2p:generateProto, so they stay out of the diff. p2p tracks rootProject.grpcVersion rather than pinning libp2p's own gRPC version, so the module cannot drift from the Netty the rest of the build resolves. --- p2p/.gitignore | 2 + p2p/build.gradle | 157 ++++++ .../org/tron/p2p/example/DnsExample1.java | 110 ++++ .../org/tron/p2p/example/DnsExample2.java | 170 ++++++

Kept separate so commit 1 stays diffable against the upstream tag. - log. -> logger. (158 call sites). The root lombok.config sets lombok.log.fieldName=logger, so @Slf4j generates `logger`, not `log`. - Math. -> StrictMath. (6 sites). CI enforces a check-math rule that rejects java.lang.Math anywhere in the tree, to keep arithmetic deterministic across JVMs and architectures. - BasicThreadFactory.builder() -> new BasicThreadFactory.Builder() (13 sites). builder() needs commons-lang3 3.12+; the project pins 3.4 globally. Rewriting to the 3.0 API keeps that pin rather than forcing a silent global upgrade. - toLowerCase()/toUpperCase() -> Locale.ROOT (4 sites). The root build enables errorprone StringCaseLocaleUsage as ERROR on every subproject except protocol and errorprone, so this is compile-forced. It is the one change here that is not purely cosmetic: behaviour is identical for ASCII but differs under a Turkish locale. Matches the project's own idiom in Args.java:1273. Formatting: google-java-format over the 9 vendored org/web3j/** files, which came in AOSP 4-space style, plus import reordering and hand fixes for the remainder. This takes :p2p:checkstyleMain from 605 violations to 0. No functional change beyond the Locale.ROOT note above. --- .../org/tron/p2p/example/DnsExample1.java | 1 - .../org/tron/p2p/example/DnsExample2.java | 1 - .../java/org/tron/p2p/example/StartApp.java | 41 +- .../main/java/org/tron/p2p/P2pService.java | 4 +- .../java/org/tron/p2p/base/Parameter.java | 11 +- .../java/org/tron/p2p/connection/Channel.java | 18 +- .../tron/p2p/connection/ChannelManager.java | 27 +- .../business/detect/NodeDetectService.java | 8 +- .../connection/business/detect/NodeStat.java | 3 +- .../business/handshake/HandshakeService.java | 6 +- .../business/keepalive/KeepAliveService.java | 4 +- .../business/pool/ConnPoolService.java | 29 +- .../business/upgrade/UpgradeController.java | 4 +- .../p2p/connection/message/MessageType.java | 1 + .../message/handshake/HelloMessage.java | 6 +- .../p2p/connection/socket/MessageHandler.java | 4 +- .../socket/P2pChannelInitializer.java | 8 +- .../P2pProtobufVarint32FrameDecoder.java | 2 +- .../p2p/connection/socket/PeerClient.java | 6 +- .../p2p/connection/socket/PeerServer.java | 15 +- .../tron/p2p/discover/DiscoverService.java | 3 +- .../main/java/org/tron/p2p/discover/Node.java | 6 +- .../p2p/discover/message/MessageType.java | 1 + .../discover/protocol/kad/DiscoverTask.java | 10 +- .../p2p/discover/protocol/kad/KadService.java | 4 +- .../discover/protocol/kad/NodeHandler.java | 4 +- .../protocol/kad/table/NodeEntry.java | 2 +- .../protocol/kad/table/NodeTable.java | 6 +- .../p2p/discover/socket/DiscoverServer.java | 16 +- .../p2p/discover/socket/MessageHandler.java | 10 +- .../p2p/discover/socket/P2pPacketDecoder.java | 12 +- .../java/org/tron/p2p/dns/DnsManager.java | 8 +- .../main/java/org/tron/p2p/dns/DnsNode.java | 1 - .../org/tron/p2p/dns/lookup/LookUpTxt.java | 32 +- .../java/org/tron/p2p/dns/sync/Client.java | 12 +- .../org/tron/p2p/dns/sync/ClientTree.java | 16 +- .../org/tron/p2p/dns/sync/RandomIterator.java | 20 +- .../org/tron/p2p/dns/sync/SubtreeSync.java | 1 - .../java/org/tron/p2p/dns/tree/Algorithm.java | 1 - .../org/tron/p2p/dns/tree/BranchEntry.java | 3 +- .../java/org/tron/p2p/dns/tree/LinkEntry.java | 1 - .../org/tron/p2p/dns/tree/NodesEntry.java | 1 - .../java/org/tron/p2p/dns/tree/RootEntry.java | 5 +- .../main/java/org/tron/p2p/dns/tree/Tree.java | 8 +- .../org/tron/p2p/dns/update/AliClient.java | 42 +- .../org/tron/p2p/dns/update/AwsClient.java | 43 +- .../java/org/tron/p2p/dns/update/Publish.java | 1 - .../tron/p2p/dns/update/PublishConfig.java | 1 - .../tron/p2p/dns/update/PublishService.java | 38 +- .../java/org/tron/p2p/stats/TrafficStats.java | 3 +- .../java/org/tron/p2p/utils/ByteArray.java | 2 +- .../main/java/org/tron/p2p/utils/NetUtil.java | 32 +- .../java/org/tron/p2p/utils/ProtoUtil.java | 1 - .../java/org/web3j/crypto/ECDSASignature.java | 85 +-- .../main/java/org/web3j/crypto/ECKeyPair.java | 166 +++-- p2p/src/main/java/org/web3j/crypto/Hash.java | 209 +++--- p2p/src/main/java/org/web3j/crypto/Sign.java | 597 +++++++++--------- .../exceptions/MessageDecodingException.java | 24 +- .../exceptions/MessageEncodingException.java | 24 +- .../main/java/org/web3j/utils/Assertions.java | 32 +- .../main/java/org/web3j/utils/Numeric.java | 356 +++++------ .../main/java/org/web3j/utils/Strings.java | 71 ++- 62 files changed, 1065 insertions(+), 1044 deletions(-) diff --git a/p2p/src/example/java/org/tron/p2p/example/DnsExample1.java b/p2p/src/example/java/org/tron/p2p/example/DnsExample1.java index 09b563101d1..eacd859ae33 100644 --- a/p2p/src/example/java/org/tron/p2p/example/DnsExample1.java +++ b/p2p/src/example/java/org/tron/p2p/example/DnsExample1.java @@ -1,6 +1,5 @@ package org.tron.p2p.example;

The dom4j exclusion tail (jaxen, stax-api, msv, xsdlib, relaxngDatatype, pull-parser, xpp3) that used to sit on the libp2p dependency here does not disappear: it arrives via the Aliyun and Route53 SDKs, which are now p2p's own dependencies. The exclusions move with them, into a configurations.configureEach block in p2p/build.gradle. Dropping them would silently re-admit artifacts the project has excluded for years. Removing a dependency also removes it as a version requester, so every version the libp2p POM declared was checked against what :p2p now declares. All twelve match, except two deliberate differences: - commons-lang3: libp2p declared 3.18.0 at runtime scope, which won conflict resolution against the root's 3.4 and put 3.18.0 on :framework:runtimeClasspath. :p2p now declares 3.18.0 for the same reason. Pinning the root's 3.4 here -- which is what the module needs to *compile*, since the source uses the 3.0-compatible `new BasicThreadFactory.Builder()` -- would have shipped a 2015 release and reintroduced CVE-2025-48924. - grpc-netty: libp2p pinned 1.81.0; :p2p tracks rootProject.grpcVersion (1.83.0) so it cannot drift from the Netty the rest of the build resolves. Adding a project to the dependency graph also needs three task-dependency edges that an external jar did not, each of which Gradle reported as an implicit_dependency and answered by disabling execution optimizations: - framework's buildFullNodeJar and plugins' binaryRelease both zip up runtimeClasspath and maintain a hand-written dependsOn list of project jars. :common now exposes p2p via `api`, so p2p-1.0.0.jar is on both classpaths; without the edge a parallel build could assemble the shipped fat jar before :p2p:jar exists. - p2p's own processExampleResources reads src/example/resources, which the protobuf plugin claims as an output of generateExampleProto because generatedFilesBaseDir points at $projectDir/src. verification-metadata.xml gains three components that resolve once p2p compiles in-tree: bcutil-jdk18on:1.84, gson:2.9.0 and gson-parent:2.9.0. Checksums were taken from Maven Central and cross-checked against the published .sha1. gson 2.9.0 is older than the 2.14.0 used elsewhere, and that is fine: it only appears on :p2p's isolated compile classpath. :framework's runtimeClasspath still resolves gson:2.9.0 -> 2.14.0. Verified with :framework:dependencies and :framework:dependencyInsight on runtimeClasspath: `project :p2p` present, no external libp2p artifact, gson at 2.14.0 and commons-lang3 at 3.18.0 -- the same versions the node shipped before. A full build reports zero implicit_dependency warnings. --- common/build.gradle | 18 +----------------- framework/build.gradle | 8 +++++++- gradle/verification-metadata.xml | 21 +++++++++++++++++++++ p2p/build.gradle | 28 +++++++++++++++++++++++++--- plugins/build.gradle | 5 ++++- 5 files changed, 58 insertions(+), 22 deletions(-) diff --git a/common/build.gradle b/common/build.gradle index 14d3eb4e637..fbab0385d7c 100644 --- a/common/build.gradle +++ b/common/build.gradle @@ -21,23 +21,7 @@ dependencies { api 'org.aspectj:aspectjrt:1.9.8' api 'org.aspectj:aspectjweaver:1.9.8' api 'org.aspectj:aspectjtools:1.9.8' - api group: 'io.github.tronprotocol', name: 'libp2p', version: '2.2.9',{ - exclude group: 'io.grpc', module: 'grpc-context' - exclude group: 'io.grpc', module: 'grpc-core' - exclude group: 'io.grpc', module: 'grpc-netty' - exclude group: 'com.google.protobuf', module: 'protobuf-java' - exclude group: 'com.google.protobuf', module: 'protobuf-java-util' - // https://github.com/dom4j/dom4j/pull/116 - // https://github.com/gradle/gradle/issues/13656 - // https://github.com/dom4j/dom4j/issues/99 - exclude group: 'jaxen', module: 'jaxen' - exclude group: 'javax.xml.stream', module: 'stax-api' - exclude group: 'net.java.dev.msv', module: 'xsdlib' - exclude group: 'pull-parser', module: 'pull-parser' - exclude group: 'xpp3', module: 'xpp3' - exclude group: 'org.bouncycastle', module: 'bcprov-jdk18on' - exclude group: 'org.bouncycastle', module: 'bcutil-jdk18on' - } + api project(":p2p") api project(":protocol") api project(":platform") } diff --git a/framework/build.gradle b/framework/build.gradle index 8255fc30d18..9127940af44 100644 --- a/framework/build.gradle +++ b/framework/build.gradle @@ -187,8 +187,14 @@ def binaryRelease(taskName, jarName, mainClass) { } // explicit_dependency + // :p2p is included because :common now exposes it via `api project(":p2p")`, + // so p2p-1.0.0.jar is on runtimeClasspath and gets zipped into the fat jar. + // Without it Gradle reports an implicit_dependency and disables execution + // optimizations, and a parallel build could assemble FullNode.jar before + // :p2p:jar has been written. dependsOn (project(':actuator').jar, project(':consensus').jar, project(':chainbase').jar, - project(':crypto').jar, project(':common').jar, project(':protocol').jar, project(':platform').jar) + project(':crypto').jar, project(':common').jar, project(':protocol').jar, + project(':platform').jar, project(':p2p').jar) from { configurations.runtimeClasspath.collect { diff --git a/gradle/verification-metadata.xml b/gradle/verification-metadata.xml index 6a3e641d5d6..d603780e242 100644 --- a/gradle/verification-metadata.xml +++ b/gradle/verification-metadata.xml @@ -448,6 +448,14 @@ + + + + + + + + @@ -463,6 +471,11 @@ + + + + + @@ -1985,6 +1998,14 @@ + + + + + + + + diff --git a/p2p/build.gradle b/p2p/build.gradle index b9dba1dad64..f49cce2d4db 100644 --- a/p2p/build.gradle +++ b/p2p/build.gradle @@ -119,9 +119,22 @@ dependencies { exclude group: 'xpp3', module: 'xpp3' } - // commons-lang3: root provides 3.4 as 'implementation' (not on compile classpath). - // Re-declare here so p2p can compile.

Package names are preserved. None of the four rewrites from the previous commit applied: the test sources use none of those patterns. Build wiring: - The AWS Route53 and Aliyun SDKs plus dnsjava are added as testImplementation. They are implementation-scope in :p2p and so are not transitively visible here, but the DNS tests need them. - Those SDKs drag in the same dom4j tail that :p2p excludes module-wide. Without mirroring the exclusions, dependency verification fails on 9 artifacts. They are mirrored scoped to test configurations only, leaving the main runtime classpath untouched. - :framework:jacocoTestReport now includes p2p's class and source dirs. :p2p has no test sourceSet, so :p2p:jacocoTestReport emits nothing, and this report covered framework's classes only, leaving p2p at zero packages despite being exercised by these tests. Generated protobuf code is excluded, matching the checkstyle exclusion. Moving these into framework's test JVM changes their isolation requirements: the task uses forkEvery = 100, so up to 100 classes share a process, whereas in libp2p's own module each ran alone (and its CI never ran tests at all). Three places leaked process-wide state and now clean up after themselves: - ConnPoolServiceTest and SocketTest call ChannelManager.close(), which latches a static isShutdown that init() never clears. Left set, every later test that starts p2p gets a PeerClient whose connect() returns null and a ConnPoolService that skips reconnection -- an order-dependent failure that is painful to diagnose. Both teardowns reset it. - HandshakeServiceTest saves and restores Parameter.handlerList instead of clearing it, since that is the registry P2pService.register() appends to. - DnsManagerTest restores DnsManager's statics rather than leaving them pointing at mocks from a finished class. Four upstream tests were unreliable by construction rather than merely flaky: - NetUtilTest.testGetIP called three public IP-echo services and asserted all three returned the same string. That needs the network and assumes a single egress address. It now runs against a loopback HttpServer, which exercises the same fetch/parse/validate path deterministically and reaches the rejection branches too. - NetUtilTest.testGetLanIP compared getLanIP() against the source address the kernel picks for a socket to www.baidu.com. Those are different definitions -- interface enumeration versus the routing table -- and disagree on any multi-homed host. It now asserts the contract getLanIP() actually has, and needs no network. - NetUtilTest.testExternalIp dereferenced a result that is null when every IP-echo service fails. It now assumes a result before asserting the address is routable. - ConnPoolServiceTest.getNodes_orderByUpdateTimeDesc asserted the returned list was ordered by updateTime. getNodes() sorts, truncates to max(limit * 10, 50) candidates, then calls Collections.shuffle() -- with two nodes that assertion is a coin flip. It now asserts membership, and a new test covers the descending sort where it is observable: above the candidate bound. NodeHandlerTest also loses an unused org.checkerframework import that does not resolve on this classpath. Eight test classes are added for code the upstream suite did not reach: ByteArray, PublishService config validation and static-node publishing, the varint32 frame decoder that fronts every channel pipeline, AwsClient's change computation, AliClient's request/retry/pagination logic, HandshakeService's accept and reject branches, DnsManager's node filtering, Channel's value semantics, and the DisconnectCode to DisconnectReason mapping. Where a collaborator is genuinely external -- the Aliyun SDK, process-wide ChannelManager state -- it is mocked, so the logic under test is real and only the transport is faked. This takes p2p from 35% line coverage on the upstream tests alone to 60.90% (2142/3517), clearing the >60% changed-line gate. What is still uncovered needs a live connection: ConnPoolService.onConnect/onDisconnect/onMessage, NodeDetectService, PeerClient, Channel.init/send. Upstream's SocketTest for exactly that is entirely commented out, so it would take integration tests with real channels rather than more unit tests. Two pre-existing libp2p defects surfaced while writing these and are reported in the PR description rather than fixed here, since this PR claims no functional change: RootEntry.java:67 and Algorithm.java:121 both throw unchecked exceptions that escape a catch(DnsException) written to tolerate unparseable input, so one malformed TXT record aborts the whole publish or collection. ---

The types arrive three hops away, through :common -> :crypto -> :chainbase, because common exposes p2p with `api project(":p2p")`. That export is not a mistake and is not removable here: CommonParameter publishes `P2pConfig p2pConfig` and `PublishConfig dnsPublishConfig` as public @Getter fields, so p2p types are part of :common's own API surface. Narrowing it to `implementation` would break every caller of getP2pConfig(). Actually de-coupling the graph means moving those fields out of CommonParameter, which is a functional refactor and out of scope for this PR. What is fixable now is the undeclared direct use. Declare it, so framework does not depend on an unrelated module's export choice for code it uses itself. api rather than implementation, because framework re-exports p2p types itself: P2pEventHandlerImpl extends org.tron.p2p.P2pEventHandler, HelloMessage.getFrom() returns org.tron.p2p.discover.Node, PeerManager.add/remove take org.tron.p2p.connection.Channel, and Args.loadDnsPublishConfig returns PublishConfig. implementation would compile today only because the transitive api chain still supplies those types to consumers -- the moment that chain is narrowed, it breaks.

The test still passed, but only because Node.equals compares getIdString(): the surviving farNode satisfies closest.contains(nearNode). Nothing the method claims to check was actually checked -- the comment "nearnode's distance is 252, far's is 255, others' are 253" was never exercised. Give each node its own array. Those three distances now hold: with the home id all zeros, distance is 256 minus the leading zero bits of the id, so 0x0F -> 252, 0x11 -> 253, 0x46 -> 255. Also assert what the trailing comment already promised but never verified -- that the farthest node is excluded, and that the result is capped at BUCKET_SIZE. Confirmed both bite: restoring the shared array makes the test fail on the new assertion. Unrelated and pre-existing: this class cannot run on its own, because it reads Parameter.p2pConfig without setting it and depends on another test class having initialised it. Verified against the unmodified branch -- running the class alone fails there too.

The cause is precise -- this PR wires p2p's classes into :framework:jacocoTestReport, which adds 16,568 instructions at 60.91% to the repo-wide denominator. Excluding p2p the PR sits at 79.70%, a delta of +0.04, so every point of the drop comes from vendored code now being counted. This is the first batch of tests aimed at that gap, covering the parts that are pure logic and need no live connection: - org/web3j/utils: Numeric, Strings, Assertions, and both message exceptions - org/web3j/crypto: Hash digests, Sign sign/recover round trips, ECKeyPair value semantics, ECDSASignature canonicalisation - UpgradeController: the per-peer compression negotiation, both legacy paths - kad discovery messages: ping/pong/find-node/neighbours through their own bytes - StatusMessage, P2pDisconnectMessage - TrafficStats and StatsManager - AwsClient batching: the 32000-byte and 1000-change Route53 limits, UPSERT counting double, makeDeletionChanges, isSubdomain - MessageHandler: every P2pException to DisconnectReason branch - P2pService: the public entry point, which had no test at all Two pre-existing test defects surfaced and are fixed here because they made coverage depend on fork scheduling rather than on what the tests assert: - ConnPoolServiceTest and SocketTest both bound fixed ports (10000, 10001).

Seeding the below-threshold case had to go through describeDomainRecords rather than the serverNodes field: deploy() calls collectRecords first, which overwrites that set from the DNS response.

It tested the opposite of its name. Replaced with two tests that build the Endpoint proto directly, one missing its address and one missing its node id, and assert both are rejected. - AliClientDeployTest.deployClearsServerNodesAfterwards could not fail: collectRecords() reassigns serverNodes on the way into deploy(), so the planted value was gone regardless. Rewritten to assert what is actually worth pinning -- a stale cached node does not survive the round trip. - SignTest asserted the public key rendered to at most 128 hex chars, which a truncated key also satisfies. Now asserts the exact 64-byte length, on the zero-padded form since toHexStringNoPrefix drops leading zeros. Two were global-state leaks that would have made later tests in the same fork depend on this one: - P2pServiceTest registered a handler for type 0x7A into Parameter.handlerMap and handlerList and never removed it. Both registries are now snapshotted and restored. - ChannelCoreTest calls close(), which bans the peer address for DEFAULT_BAN_TIME in a process-wide cache. A leftover ban on 127.0.0.1 would make any later test see a recently-disconnected peer. The cache is now cleared around each test. The sixth comment, that StatusMessageTest rewrites Parameter.p2pConfig and clears ChannelManager.channels, is accurate but describes how every p2p test in this tree already works, including the ones that predate this branch. Left alone rather than diverging one file from the convention.

That reading does not hold up: chainbase and consensus have no tests at all, and actuator has one -- so they are not evidence of a convention. The two modules that do have their own tests, common (13 files) and plugins (19), keep them in the module. Moving them here also deletes two workarounds that only existed because :p2p had no test sourceSet: - framework/build.gradle re-declared route53, alidns and dnsjava as testImplementation, because they are implementation-scope in :p2p and so invisible to another module's test classpath. It also had to mirror the dom4j exclusion tail onto every test configuration to keep dependency verification passing. In :p2p, testImplementation extends implementation, so both blocks are unnecessary -- the relocated tests compiled first try without them. - :framework:jacocoTestReport had p2p's class and source dirs bolted on with additionalClassDirs/additionalSourceDirs, because :p2p:jacocoTestReport produced nothing without exec data. :p2p now reports for itself. CI collects **/build/reports/jacoco/test/jacocoTestReport.xml across every module, so it is picked up with no wiring at all; the protos exclusion moves into the module's own report block. Coverage is unchanged by the move: 78.88% instruction, 78.12% line, the same figures the combined report produced. Three tests used framework's PublicMethod.chooseRandomPort. :p2p cannot depend on :framework -- that is a cycle -- so the same few lines live in p2p/src/test/java/org/tron/p2p/utils/TestPort. Separate test tasks also let Gradle run :p2p:test and :framework:test in parallel. 345 tests, 0 failures, 3 skipped. :p2p:checkstyleMain and :p2p:checkstyleTest both clean. --- framework/build.gradle

Each ended in a `while (true)` loop, bound a fixed port and pointed at live seed nodes, so nothing they demonstrated was checked -- and cubic found real defects sitting in them: `TestMessage` is not serializable so `ByteArray.fromObject` returns null and `Channel.send` closes the channel, and `DnsExample1` carried a signing private key in copyable code. Porting them line by line would produce three slow, network-dependent, port-bound tests. What is worth pinning is the contract they advertised: those configuration shapes are still accepted and still mean what the comments said. External embedders copy them, so a renamed setter or tightened validation is a breaking change even though nothing in this repo calls them. `ExampleUsageTest` covers all three shapes -- the connection-tuning surface, the register/start/query/close lifecycle on a free port with discovery off, the duplicate-message-type rejection, the AwsRoute53 publish config, and the discovery-off + tree-urls sync config. The signing key moves into the test as a fixture; it is upstream's well-known test key, already used by AlgorithmTest, and an embedder has to supply their own. `StartApp` moves to `src/main/java` and stays, as the entry point for debugging the module without starting java-tron. Moving it out of the exempt sourceSet subjects it to the project's checkstyle for the first time: three over-long lines, wrapped. It also carried a real bug. `--trust-ips` is declared as `ip[,ip[...]]` but resolved the whole comma-separated value as a single hostname, so with more than one address none of the listed peers became trusted. It now splits and resolves each, skipping and logging any that do not resolve. The `example` sourceSet and all of its build wiring are gone: the sourceSet block, the two extendsFrom configurations, the checkstyle opt-out, the encoding override, the Lombok wiring, and the `processExampleResources` task edge that only existed because `generatedFilesBaseDir` points into `src/`. 351 tests, 0 failures, 3 skipped. `:p2p:build` clean. --- p2p/build.gradle | 42 ---- .../org/tron/p2p/example/DnsExample1.java | 109 --------- .../org/tron/p2p/example/DnsExample2.java | 169 ------------- .../org/tron/p2p/example/ImportUsing.java | 201 ---------------- .../java/org/tron/p2p/example/StartApp.java | 33 ++- .../tron/p2p/example/ExampleUsageTest.java | 224 ++++++++++++++++++ 6 files changed, 250 insertions(+), 528 deletions(-) delete mode 100644 p2p/src/example/java/org/tron/p2p/example/DnsExample1.java delete mode 100644 p2p/src/example/java/org/tron/p2p/example/DnsExample2.java delete mode 100644 p2p/src/example/java/org/tron/p2p/example/ImportUsing.java rename p2p/src/{example => main}/java/org/tron/p2p/example/StartApp.java (93%) create mode 100644 p2p/src/test/java/org/tron/p2p/example/ExampleUsageTest.java diff --git a/p2p/build.gradle b/p2p/build.gradle index 773a495f450..a9a4ae3bc26 100644 --- a/p2p/build.gradle +++ b/p2p/build.gradle @@ -2,10 +2,6 @@ apply plugin: 'com.google.protobuf' apply plugin: 'checkstyle' // Unit tests live in src/test/java/, alongside the code they cover. -// -// Reference code for using p2p as a library lives in src/example/java/.

It is argument parsing, option declarations and a main() that starts services and blocks: not module logic, and not code the node runs. `org/tron/p2p/example/**` is now excluded from this module's report alongside `**/protos/**`, which keeps the measured surface the same as before the move rather than hiding newly counted logic. The two parsing helpers it does own are real logic, and one of them shipped the `--trust-ips` bug fixed in the previous commit, so they are package-private now and `StartAppArgsTest` covers them: comma splitting, whitespace, unresolvable entries, and the bracketed-IPv6 form of `parseInetSocketAddressList`. The exclusion does not take regression protection with it. **Coverage that stopped being attributed.** :framework's own tests execute p2p code, and while p2p's classes hung off :framework:jacocoTestReport that was counted. :p2p:jacocoTestReport now reads framework's exec data too, so it keeps being counted. Worth noting it recovers only 70 instructions, not the ~700 the earlier measurements suggested -- the tests added in this PR already cover most of what framework's tests were reaching. The fileTree is empty when :framework:test has not run, so :p2p:build alone still works. p2p instruction coverage: 79.32% (12,625/15,917), against 78.88% on the last run that passed the gate. --- p2p/build.gradle | 23 +++++- .../java/org/tron/p2p/example/StartApp.java | 6 +- .../tron/p2p/example/StartAppArgsTest.java | 71 +++++++++++++++++++ 3 files changed, 97 insertions(+), 3 deletions(-) create mode 100644 p2p/src/test/java/org/tron/p2p/example/StartAppArgsTest.java diff --git a/p2p/build.gradle b/p2p/build.gradle index b9ddcc74f2d..070ed29a71d 100644 --- a/p2p/build.gradle +++ b/p2p/build.gradle @@ -153,9 +153,30 @@ jacocoTestReport { html.required = false } // Generated protobuf code, matching the checkstyle exclusion above. + // + // org/tron/p2p/example holds StartApp, the standalone CLI entry point for + // driving this module without java-tron.

That is worse than declaring nothing -- it advertises support that cannot work. I had only verified the `-cp` form documented in the README, not `java -jar` itself. The plain jar drops `Main-Class` again and now fails honestly with "no main manifest attribute". `buildStandaloneJar` produces `p2p-standalone.jar` with the runtime classpath bundled, following :framework's FullNode.jar and :plugins' Toolkit.jar -- same `artifacts { archives(...) }` wiring, the same `-PbinaryRelease=false` opt-out, and the same exclusions for Bouncy Castle's signatures and dnsjava's resolver SPI. Verified by running it: `java -jar p2p/build/libs/p2p-standalone.jar --help` prints the help. The `printRuntimeClasspath` helper is gone; it existed only to work around the thin jar. **The README still read as upstream's.** Four source links pointed at github.com/tronprotocol/libp2p and the prose described libp2p as a standalone project. Links are module-relative now, the prose talks about this module, and the header states the provenance once and explains which of the two jars to use. The one remaining upstream link is that attribution. **Duplicated versions.** `protobufVersion` 3.25.8 was declared in both :protocol and :p2p; checkstyle 8.7 sat in a local `versions` map in :framework and :plugins and as a literal in :p2p. Both move to the root `ext` beside `grpcVersion` and `nettyVersion`, and all four modules reference them, so the duplication is removed rather than relocated. Resolution is unchanged: `protobuf-java:3.25.8` on :p2p's compile classpath. --- build.gradle | 4 +++ framework/build.gradle | 6 ++-- p2p/README.md | 73 ++++++++++++++++++++++++------------------ p2p/build.gradle | 49 +++++++++++++++++++++------- plugins/build.gradle | 6 ++-- protocol/build.gradle | 7 ++-- 6 files changed, 90 insertions(+), 55 deletions(-) diff --git a/build.gradle b/build.gradle index 039e04d9e12..a03474d6785 100644 --- a/build.gradle +++ b/build.gradle @@ -14,6 +14,10 @@ ext { // grpcVersion above — keeping it here makes that coupling visible instead of // leaving two literals to drift apart. nettyVersion = "4.2.15.Final" + // Shared by :protocol and :p2p, which both generate from .proto files. + protobufVersion = "3.25.8" + // Shared by :framework, :plugins and :p2p. + checkstyleVersion = "8.7" } allprojects { diff --git a/framework/build.gradle b/framework/build.gradle index 385f638d630..8edd6714f95 100644 --- a/framework/build.gradle +++ b/framework/build.gradle @@ -11,9 +11,7 @@ apply plugin: 'checkstyle' mainClassName = 'org.tron.program.FullNode' -def versions = [ - checkstyle: '8.7', -] + @@ -82,7 +80,7 @@ dependencies { check.dependsOn 'lint' checkstyle { - toolVersion = "${versions.checkstyle}" + toolVersion = "${rootProject.checkstyleVersion}" configFile = file("config/checkstyle/checkStyleAll.xml") maxWarnings = 0 } diff --git a/p2p/README.md b/p2p/README.md index da694a44729..a94c4587bd1 100644 --- a/p2p/README.md +++ b/p2p/README.md @@ -1,29 +1,40 @@ -> **Vendored module.** This is `tronprotocol/libp2p` v2.2.9 living inside -> java-tron as the `:p2p` Gradle module. java-tron consumes it as a project -> dependency, not as a published artifact — `:common` exposes it via -> `api project(":p2p")`.
