From 03b45a23a52eea25cce3e118c35562c5f2dcab63 Mon Sep 17 00:00:00 2001 From: Aleksandar Maksimovic Date: Wed, 24 Dec 2025 11:42:48 -0800 Subject: [PATCH] Prepare samples repo for connector sync Java pgjdbc changes: - Rename package from org.example to software.amazon.dsql.examples - Switch from Maven to Gradle build system (matching connector) - Add gradle wrapper for standalone builds - Update workflow to use Gradle - Update README to match connector Python asyncpg changes: - Add new python/asyncpg folder with examples from connector - Add integration test workflow for asyncpg This aligns the samples repo structure with the connector repos to enable automated syncing of examples. --- .github/workflows/java-pgjdbc-integ-tests.yml | 8 +- .../workflows/python-asyncpg-integ-tests.yml | 70 +++++ java/pgjdbc/README.md | 23 +- java/pgjdbc/build.gradle.kts | 13 +- java/pgjdbc/gradle/wrapper/gradle-wrapper.jar | Bin 0 -> 45457 bytes .../gradle/wrapper/gradle-wrapper.properties | 7 + java/pgjdbc/gradlew | 248 ++++++++++++++++++ java/pgjdbc/gradlew.bat | 93 +++++++ java/pgjdbc/pom.xml | 101 ------- java/pgjdbc/settings.gradle.kts | 4 +- .../dsql/examples}/ExamplePreferred.java | 7 +- .../dsql/examples}/alternatives/README.md | 2 +- .../ExampleWithNoConnectionPool.java | 7 +- .../ExampleWithNoConnector.java | 7 +- .../dsql/examples}/ExamplePreferredTest.java | 9 +- .../ExampleWithNoConnectionPoolTest.java | 7 +- .../ExampleWithNoConnectorTest.java | 7 +- python/asyncpg/README.md | 159 +++++++++++ python/asyncpg/pyproject.toml | 37 +++ python/asyncpg/requirements.txt | 4 + python/asyncpg/src/alternatives/README.md | 27 ++ python/asyncpg/src/alternatives/__init__.py | 0 .../no_connection_pool/__init__.py | 0 .../example_with_no_connection_pool.py | 95 +++++++ .../asyncpg/src/alternatives/pool/__init__.py | 0 ...mple_with_nonconcurrent_connection_pool.py | 58 ++++ python/asyncpg/src/example_preferred.py | 73 ++++++ .../test_example_with_no_connection_pool.py | 16 ++ ...mple_with_nonconcurrent_connection_pool.py | 16 ++ python/asyncpg/test/test_example_preferred.py | 16 ++ 30 files changed, 981 insertions(+), 133 deletions(-) create mode 100644 .github/workflows/python-asyncpg-integ-tests.yml create mode 100644 java/pgjdbc/gradle/wrapper/gradle-wrapper.jar create mode 100644 java/pgjdbc/gradle/wrapper/gradle-wrapper.properties create mode 100755 java/pgjdbc/gradlew create mode 100644 java/pgjdbc/gradlew.bat delete mode 100644 java/pgjdbc/pom.xml rename java/pgjdbc/src/main/java/{org/example => software/amazon/dsql/examples}/ExamplePreferred.java (97%) rename java/pgjdbc/src/main/java/{org/example => software/amazon/dsql/examples}/alternatives/README.md (87%) rename java/pgjdbc/src/main/java/{org/example => software/amazon/dsql/examples}/alternatives/no_connection_pool/ExampleWithNoConnectionPool.java (94%) rename java/pgjdbc/src/main/java/{org/example => software/amazon/dsql/examples}/alternatives/no_connection_pool/ExampleWithNoConnector.java (96%) rename java/pgjdbc/src/test/java/{org/example => software/amazon/dsql/examples}/ExamplePreferredTest.java (60%) rename java/pgjdbc/src/test/java/{org/example => software/amazon/dsql/examples}/alternatives/no_connection_pool/ExampleWithNoConnectionPoolTest.java (59%) rename java/pgjdbc/src/test/java/{org/example => software/amazon/dsql/examples}/alternatives/no_connection_pool/ExampleWithNoConnectorTest.java (58%) create mode 100644 python/asyncpg/README.md create mode 100644 python/asyncpg/pyproject.toml create mode 100644 python/asyncpg/requirements.txt create mode 100644 python/asyncpg/src/alternatives/README.md create mode 100644 python/asyncpg/src/alternatives/__init__.py create mode 100644 python/asyncpg/src/alternatives/no_connection_pool/__init__.py create mode 100644 python/asyncpg/src/alternatives/no_connection_pool/example_with_no_connection_pool.py create mode 100644 python/asyncpg/src/alternatives/pool/__init__.py create mode 100644 python/asyncpg/src/alternatives/pool/example_with_nonconcurrent_connection_pool.py create mode 100644 python/asyncpg/src/example_preferred.py create mode 100644 python/asyncpg/test/alternatives/no_connection_pool/test_example_with_no_connection_pool.py create mode 100644 python/asyncpg/test/alternatives/pool/test_example_with_nonconcurrent_connection_pool.py create mode 100644 python/asyncpg/test/test_example_preferred.py diff --git a/.github/workflows/java-pgjdbc-integ-tests.yml b/.github/workflows/java-pgjdbc-integ-tests.yml index 87706fd1..908c4a09 100644 --- a/.github/workflows/java-pgjdbc-integ-tests.yml +++ b/.github/workflows/java-pgjdbc-integ-tests.yml @@ -40,7 +40,7 @@ jobs: java-version: '17' distribution: 'corretto' architecture: x64 -
