feat: add compile-time i18n for log and exception messages#17613
Merged
Conversation
Add Maven-based compile-time internationalization infrastructure that
switches between English and Chinese message constants via profile,
with zero runtime overhead (javac inlines static final String constants).
Build commands:
mvn clean package -DskipTests # English (default)
mvn clean package -DskipTests -Pwith-zh-locale # Chinese
Infrastructure:
- Add i18n.locale property (default: en) and with-zh-locale profile
- Configure build-helper-maven-plugin to add src/main/i18n/${i18n.locale}
as additional source directory
Message constant classes (25 en + 25 zh = 50 files):
- node-commons: AuthMessages, ClientMessages, CommonMessages,
ConfigMessages, PathMessages, PipeMessages, QueryMessages,
SchemaMessages, ServiceMessages, UtilMessages
- datanode: StorageEngineMessages, DataNodeQueryMessages,
DataNodePipeMessages, DataNodeSchemaMessages, DataNodeMiscMessages
- confignode: ConfigNodeMessages, ManagerMessages, ProcedureMessages
- consensus: ConsensusMessages, IoTConsensusMessages,
IoTConsensusV2Messages, RatisMessages
- session: SessionMessages
- cli: CliMessages
- jdbc: JdbcMessages
4635 hardcoded strings replaced with compile-time constants across
7 modules.

Add compile-time i18n message constants for service-rpc, calc-commons, library-udf, udf-api, metrics/interface, metrics/core, subscription, isession, mqtt, rest, pipe-api, and trigger-api modules.
…sus, confignode, session, and partial node-commons/datanode
…ssages - Replace ~230 hardcoded strings with i18n constants across all target modules - Modules covered: datanode, confignode, node-commons, consensus, calc-commons - Add Chinese translations for all new constants in zh locale files - Add CI compile check for Chinese locale build - Update README/README_ZH/CLAUDE.md with Chinese build instructions - Both EN and ZH locale compilation verified
Apply fixes from code review of ty/chinese i18n PR: - Remove unused PipeMessages.PATH_TRAVERSAL_DETECTED (P0: EN/ZH inconsistency) - Replace prefix/suffix fragment concatenation with String.format in CalcMessages, JdbcMessages, DataNodeQueryMessages so single-placeholder format strings are used end-to-end - Rename short/ambiguous constants: DataNodeQueryMessages.VS -> TYPE_MISMATCH_FMT; drop the OF/EXISTS fragments in favour of SOURCE_HANDLE_FOR_PLAN_NODE_EXISTS_FMT - Shorten three 70+ char constant names in confignode (Manager/Procedure messages) - Remove unused SessionMessages.REDIRECT_TWICE_EXCEPTION/REDIRECT_TWICE_SUFFIX; move local REDIRECT_TWICE/REDIRECT_TWICE_RETRY out of Session.java and split into REDIRECT_TWICE_LOG[_WITH_SQL] / REDIRECT_TWICE_MSG[_WITH_SQL] pairs
