dianjifzm opened a new issue, #13743: URL: https://github.com/apache/dubbo/issues/13743
<!-- If you need to report a security issue please visit https://github.com/apache/dubbo/security/policy --> ### Environment * Dubbo version: 3.2.11 * Operating System version: Apple M2芯片 macOS 14.2.1 * Java version: OpenJDK 64-Bit Server VM (build 21.0.2+13-58, mixed mode, sharing) ### 复现方式1 ``` public static void main(String[] args) throws Exception { NetUtils.getLocalHost(); long l = System.currentTimeMillis(); NetUtils.getLocalHost(); System.out.println("use " + (System.currentTimeMillis() - l) + "ms"); System.out.println(); } ``` 多数情况下，第二次调用NetUtils.getLocalHost() 会使用极短时间，因为HOST_ADDRESS已经缓存了上次调用的结果 但是在Apple M2芯片 macOS 14.2.1 环境下，非root用户执行 InetAddress.isReachable 会一直返回false，这导致了HOST_ADDRESS赋值失败。 ### 复现方式2 因为几乎每行日志都使用了NetUtils.getLocalHost()，这最终导致了dubbo整体启动时间的大幅度上涨 下面日志是 root用户和普通用户调用FrameworkModel.defaultModel() 的区别（注意观察日志的时间戳） Java代码 ``` import org.apache.dubbo.rpc.model.FrameworkModel; public class FrameworkModelDemo { public static void main(String[] args) throws Exception { long l = System.currentTimeMillis(); FrameworkModel.defaultModel(); System.out.println("use " + (System.currentTimeMillis() - l) + "ms"); } } ``` 普通用户 ``` java -cp .:build:./target/dependency/* FrameworkModelDemo 2024-02-05 21:19:34.661 INFO org.apache.dubbo.rpc.model.FrameworkModel [<init>:86] [main] - [DUBBO] Dubbo Framework[1] is created, dubbo version: 3.2.11, current host: 127.0.0.1 2024-02-05 21:19:35.098 INFO org.apache.dubbo.common.resource.GlobalResourcesRepository [getExecutorService:96] [main] - [DUBBO] Creating global shared handler ..., dubbo version: 3.2.11, current host: 127.0.0.1 2024-02-05 21:19:35.569 INFO org.apache.dubbo.rpc.model.ApplicationModel [<init>:107] [main] - [DUBBO] Dubbo Application[1.0](unknown) is created, dubbo version: 3.2.11, current host: 127.0.0.1 2024-02-05 21:19:35.980 INFO org.apache.dubbo.rpc.model.ScopeModel [<init>:63] [main] - [DUBBO] Dubbo Module[1.0.0] is created, dubbo version: 3.2.11, current host: 127.0.0.1 2024-02-05 21:19:36.416 INFO org.apache.dubbo.config.context.AbstractConfigManager [initialize:143] [main] - [DUBBO] Config settings: {dubbo.config.mode=STRICT, dubbo.config.ignore-duplicated-interface=false}, dubbo version: 3.2.11, current host: 127.0.0.1 2024-02-05 21:19:36.828 INFO org.apache.dubbo.config.context.AbstractConfigManager [initialize:143] [main] - [DUBBO] Config settings: {dubbo.config.mode=STRICT, dubbo.config.ignore-duplicated-interface=false}, dubbo version: 3.2.11, current host: 127.0.0.1 2024-02-05 21:19:37.248 INFO org.apache.dubbo.common.utils.SerializeSecurityManager [setCheckSerializable:107] [main] - [DUBBO] Serialize check serializable: true, dubbo version: 3.2.11, current host: 127.0.0.1 2024-02-05 21:19:37.660 INFO org.apache.dubbo.common.utils.SerializeSecurityConfigurator [loadAllow:135] [main] - [DUBBO] Read serialize allow list from jar:file:/Users/fzming/workspace/demos/alibaba.com/dubbo3/performance_init_test/target/dependency/dubbo-3.2.11.jar!/security/serialize.allowlist, dubbo version: 3.2.11, current host: 127.0.0.1 2024-02-05 21:19:38.118 INFO org.apache.dubbo.common.utils.SerializeSecurityConfigurator [loadBlocked:159] [main] - [DUBBO] Read serialize blocked list from jar:file:/Users/fzming/workspace/demos/alibaba.com/dubbo3/performance_init_test/target/dependency/dubbo-3.2.11.jar!/security/serialize.blockedlist, dubbo version: 3.2.11, current host: 127.0.0.1 use 4077ms ``` root用户 ``` sudo java -cp .:build:./target/dependency/* FrameworkModelDemo 2024-02-05 21:20:36.077 INFO org.apache.dubbo.rpc.model.FrameworkModel [<init>:86] [main] - [DUBBO] Dubbo Framework[1] is created, dubbo version: 3.2.11, current host: 100.85.129.227 2024-02-05 21:20:36.087 INFO org.apache.dubbo.common.resource.GlobalResourcesRepository [getExecutorService:96] [main] - [DUBBO] Creating global shared handler ..., dubbo version: 3.2.11, current host: 100.85.129.227 2024-02-05 21:20:36.127 INFO org.apache.dubbo.rpc.model.ApplicationModel [<init>:107] [main] - [DUBBO] Dubbo Application[1.0](unknown) is created, dubbo version: 3.2.11, current host: 100.85.129.227 2024-02-05 21:20:36.128 INFO org.apache.dubbo.rpc.model.ScopeModel [<init>:63] [main] - [DUBBO] Dubbo Module[1.0.0] is created, dubbo version: 3.2.11, current host: 100.85.129.227 2024-02-05 21:20:36.139 INFO org.apache.dubbo.config.context.AbstractConfigManager [initialize:143] [main] - [DUBBO] Config settings: {dubbo.config.mode=STRICT, dubbo.config.ignore-duplicated-interface=false}, dubbo version: 3.2.11, current host: 100.85.129.227 2024-02-05 21:20:36.139 INFO org.apache.dubbo.config.context.AbstractConfigManager [initialize:143] [main] - [DUBBO] Config settings: {dubbo.config.mode=STRICT, dubbo.config.ignore-duplicated-interface=false}, dubbo version: 3.2.11, current host: 100.85.129.227 2024-02-05 21:20:36.144 INFO org.apache.dubbo.common.utils.SerializeSecurityManager [setCheckSerializable:107] [main] - [DUBBO] Serialize check serializable: true, dubbo version: 3.2.11, current host: 100.85.129.227 2024-02-05 21:20:36.144 INFO org.apache.dubbo.common.utils.SerializeSecurityConfigurator [loadAllow:135] [main] - [DUBBO] Read serialize allow list from jar:file:/Users/fzming/workspace/demos/alibaba.com/dubbo3/performance_init_test/target/dependency/dubbo-3.2.11.jar!/security/serialize.allowlist, dubbo version: 3.2.11, current host: 100.85.129.227 2024-02-05 21:20:36.166 INFO org.apache.dubbo.common.utils.SerializeSecurityConfigurator [loadBlocked:159] [main] - [DUBBO] Read serialize blocked list from jar:file:/Users/fzming/workspace/demos/alibaba.com/dubbo3/performance_init_test/target/dependency/dubbo-3.2.11.jar!/security/serialize.blockedlist, dubbo version: 3.2.11, current host: 100.85.129.227 use 284ms ``` -- This is an automated message from the Apache Git Service.
