From 5ebe1ab9b5f079ce4584e871460225a64e2a275a Mon Sep 17 00:00:00 2001 From: sjjian <921465802@qq.com> Date: Wed, 11 Mar 2026 10:10:41 +0000 Subject: [PATCH 01/25] feat(postgres): implement PostgresJdbcUrlParser for PG JDBC URL parsing Add PostgresJdbcUrlParser that implements JdbcUrlParser interface to parse PostgreSQL JDBC URLs. Uses string splitting (not regex) for parsing to reduce complexity. Features: - Parse standard URL: jdbc:postgresql://host:port/database - Extract schema from currentSchema parameter - Support default port 5432 when not specified - Parse multiple query parameters Includes comprehensive unit tests covering: - Standard URL parsing - URL without port (default 5432) - URL without parameters - URL with multiple parameters - currentSchema extraction - Special character handling - Null/invalid input handling Ref: AC-001.4, AC-001.5 --- .../postgres/PostgresJdbcUrlParser.java | 206 ++++++++++++++ .../postgres/PostgresJdbcUrlParserTest.java | 251 ++++++++++++++++++ 2 files changed, 457 insertions(+) create mode 100644 server/plugins/connect-plugin-postgres/src/main/java/com/oceanbase/odc/plugin/connect/postgres/PostgresJdbcUrlParser.java create mode 100644 server/plugins/connect-plugin-postgres/src/test/java/com/oceanbase/odc/plugin/connect/postgres/PostgresJdbcUrlParserTest.java diff --git a/server/plugins/connect-plugin-postgres/src/main/java/com/oceanbase/odc/plugin/connect/postgres/PostgresJdbcUrlParser.java b/server/plugins/connect-plugin-postgres/src/main/java/com/oceanbase/odc/plugin/connect/postgres/PostgresJdbcUrlParser.java new file mode 100644 index 0000000000..32f19af154 --- /dev/null +++ b/server/plugins/connect-plugin-postgres/src/main/java/com/oceanbase/odc/plugin/connect/postgres/PostgresJdbcUrlParser.java @@ -0,0 +1,206 @@ +/* + * Copyright (c) 2023 OceanBase. + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ +package com.oceanbase.odc.plugin.connect.postgres; + +import java.sql.SQLException; +import java.util.Collections; +import java.util.HashMap; +import java.util.List; +import java.util.Map; + +import com.oceanbase.odc.plugin.connect.api.HostAddress; +import com.oceanbase.odc.plugin.connect.api.JdbcUrlParser; + +import lombok.NonNull; +import lombok.extern.slf4j.Slf4j; + +/** + * PostgreSQL JDBC URL 解析器 + * + *

Original implementation skipped creating DB_SERVER_EXECUTE_SQL stage when executeMicroseconds is null, causing frontend to display '-' for DB duration. This fix adds fallback logic to use Execute stage time as approximate DB execution time, ensuring frontend can always display DB duration correctly. Fixes: E-002 PostgreSQL DB duration shows '-' Also benefits: SQLServer, Doris, MySQL(profiling=OFF), Oracle(exception) --- .../service/session/OdcStatementCallBack.java | 16 ++ .../OdcStatementCallBackTraceStageTest.java | 140 ++++++++++++++++++ 2 files changed, 156 insertions(+) create mode 100644 server/odc-service/src/test/java/com/oceanbase/odc/service/session/OdcStatementCallBackTraceStageTest.java diff --git a/server/odc-service/src/main/java/com/oceanbase/odc/service/session/OdcStatementCallBack.java b/server/odc-service/src/main/java/com/oceanbase/odc/service/session/OdcStatementCallBack.java index a1622dde8a..03ddd3c6c0 100644 --- a/server/odc-service/src/main/java/com/oceanbase/odc/service/session/OdcStatementCallBack.java +++ b/server/odc-service/src/main/java/com/oceanbase/odc/service/session/OdcStatementCallBack.java @@ -486,6 +486,22 @@ private SqlExecTime getTraceIdAndAndSetStage(Statement statement, TraceWatch tra private void setExecuteTraceStage(TraceWatch traceWatch, SqlExecTime executeDetails, StopWatch stopWatch) { if (executeDetails.getExecuteMicroseconds() == null) { + // Fallback: Use Execute stage time as approximate DB execution time + // This is useful for databases like PostgreSQL and SQLServer that don't provide + // built-in trace mechanism to get detailed execution time. + List executeStages = traceWatch.getByTaskName(SqlExecuteStages.EXECUTE); + if (executeStages != null && !executeStages.isEmpty()) { + long executeTimeMicros = executeStages.get(0).getTime(TimeUnit.MICROSECONDS); + try (EditableTraceStage dbServerExecute = + traceWatch.startEditableStage(SqlExecuteStages.DB_SERVER_EXECUTE_SQL)) { + dbServerExecute.setStartTime(executeStages.get(0).getStartTime(), TimeUnit.MICROSECONDS); + dbServerExecute.setTime(executeTimeMicros, TimeUnit.MICROSECONDS); + } + try (EditableTraceStage calculateDuration = + traceWatch.startEditableStage(SqlExecuteStages.CALCULATE_DURATION)) { + calculateDuration.adapt(stopWatch); + } + } return; } else if (executeDetails.getLastPacketSendTimestamp() == null || executeDetails.getLastPacketResponseTimestamp() == null) { diff --git a/server/odc-service/src/test/java/com/oceanbase/odc/service/session/OdcStatementCallBackTraceStageTest.java b/server/odc-service/src/test/java/com/oceanbase/odc/service/session/OdcStatementCallBackTraceStageTest.java new file mode 100644 index 0000000000..db32756232 --- /dev/null +++ b/server/odc-service/src/test/java/com/oceanbase/odc/service/session/OdcStatementCallBackTraceStageTest.java @@ -0,0 +1,140 @@ +/* + * Copyright (c) 2023 OceanBase. + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ +package com.oceanbase.odc.service.session; + +import java.io.IOException; +import java.util.List; +import java.util.concurrent.TimeUnit; + +import org.junit.Assert; +import org.junit.Test; + +import com.oceanbase.odc.common.util.TraceStage; +import com.oceanbase.odc.common.util.TraceWatch; +import com.oceanbase.odc.common.util.TraceWatch.EditableTraceStage; +import com.oceanbase.odc.core.sql.execute.SqlExecuteStages; + +/** + * Test case for the fallback logic when executeMicroseconds is null + * + *

The previous logic returned defaultSchema as catalog when it was non-empty and not "public", on the assumption that users sometimes put the database name in default_schema. That assumption breaks for the common case where default_schema is a real PG schema name (e.g. schema_a) and there is no PG database named schema_a, which triggers FATAL: database "schema_a" does not exist and blocks every sync / connection test for that datasource. Now we always fall back to OdcConstants.POSTGRESQL_DEFAULT_DATABASE ("postgres") when catalogName is blank. The front-end already keeps catalogName as a required field for PG datasource, so this is purely a defence-in-depth path for older imports and third-party callers. Unit test OBConsoleDataSourceFactoryTest is realigned: the customSchema_usesSchemaAsCatalog case is renamed to customSchema_fallsBackToPostgresDb to match the new contract; the other 11 cases (explicit catalog returns as-is; non-PG dialects untouched; etc.) continue to assert the previous behaviour. 2. DatabaseService.handleSyncException(): also clean connect_database on generic JDBC connection failure. The OceanBase-specific clauses (cluster not exist / No tenants found) were the only ones that triggered deleteDatabaseIfInstanceNotExists(). When PG syncing failed because the catalog did not exist (or the network was unreachable, or auth failed), the old database rows kept is_existed=1 and the user could not refresh the list from the UI. We add a third branch matching common JDBC connection failure markers (CannotGetJdbcConnectionException / "Failed to obtain JDBC Connection" / "FATAL: database") and reuse the same cleanup helper. Failed-reason stays UNKNOWN so the user sees the raw JDBC error in connect_sync_history but the stale database list is cleared.
