From 05f201552c5115060e2e7862bc541e234b0a6059 Mon Sep 17 00:00:00 2001 From: Feng Zhang Date: Sun, 3 Aug 2025 23:27:13 -0700 Subject: [PATCH 1/8] Expose ProllyTree SQL API to Python MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Summary This PR adds complete SQL functionality to the ProllyTree Python bindings, allowing users to execute SQL queries on the versioned key-value store through a new ProllySQLStore class. Changes Core Implementation - Added ProllySQLStore Python class (src/python.rs) - Full SQL query execution via GlueSQL - Multiple output formats: dict, tuples, JSON, CSV - Helper methods for common operations (create_table, insert, select) - Transaction support with commit functionality Python Module Updates - Updated python/prollytree/__init__.py - Conditionally exports ProllySQLStore when SQL feature is available - Graceful fallback when SQL support is not compiled Build System Enhancements - Enhanced python/build_python.sh - Added --with-sql flag to build with SQL support - Added --all-features flag for complete feature set - Added --help documentation - Automatic SQL functionality testing when built with SQL feature - Updated pyproject.toml - Added SQL feature to default maturin build configuration - Allows override via command-line flags Storage Layer - Added current_commit() method (src/git/versioned_store.rs) - Enables retrieving the current HEAD commit ID - Required for SQL commit operations Documentation & Examples - Created comprehensive SQL example (python/examples/sql_example.py) - Demonstrates table creation, data insertion, and querying - Shows all output formats (dict, tuples, JSON, CSV) - Examples of JOINs, GROUP BY, subqueries - UPDATE and DELETE operations - Added SQL test suite (python/tests/test_sql.py) - Tests for all SQL operations - Output format validation - Complex query testing - Static method testing API Usage from prollytree import ProllySQLStore # Initialize store (requires git repository) store = ProllySQLStore(path) # Create table store.create_table("users", [("id", "INTEGER"), ("name", "TEXT")]) # Insert data store.insert("users", [[1, "Alice"], [2, "Bob"]]) # Query with different formats results = store.execute("SELECT * FROM users") # Returns list of dicts labels, rows = store.execute("SELECT * FROM users", format="tuples") json_str = store.execute("SELECT * FROM users", format="json") csv_str = store.execute("SELECT * FROM users", format="csv") # Helper methods store.select("users", columns=["name"], where_clause="id > 1") # Execute multiple queries store.execute_many([query1, query2, query3]) # Commit changes store.commit("Added user data") Building with SQL Support # Build with SQL support ./python/build_python.sh --with-sql # Build and install ./python/build_python.sh --with-sql --install # Run example python3 python/examples/sql_example.py Testing - โœ… All SQL operations tested and working - โœ… Example script runs successfully - โœ… Multiple output formats validated - โœ… Complex queries (JOIN, GROUP BY) functional Breaking Changes None - SQL support is optional and doesn't affect existing functionality. Notes - SQL functionality requires git repository initialization - Based on GlueSQL, some SQL features may have limitations (e.g., no DISTINCT support) - Performance is optimized for versioned operations rather than pure SQL speed --- pyproject.toml | 3 +- python/build_python.sh | 93 +++++++- python/examples/sql_example.py | 230 +++++++++++++++++++ python/prollytree/__init__.py | 9 +- python/tests/test_sql.py | 264 ++++++++++++++++++++++ src/git/versioned_store.rs | 14 ++ src/python.rs | 395 ++++++++++++++++++++++++++++++++- 7 files changed, 1002 insertions(+), 6 deletions(-) create mode 100644 python/examples/sql_example.py create mode 100644 python/tests/test_sql.py diff --git a/pyproject.toml b/pyproject.toml index a325dfa..0248617 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -39,6 +39,7 @@ Repository = "https://github.com/zhangfengcdt/prollytree.git" "Bug Tracker" = "https://github.com/zhangfengcdt/prollytree/issues" [tool.maturin] -features = ["python"] +# Default features - can be overridden with --features flag +features = ["python", "sql"] module-name = "prollytree" python-source = "python" diff --git a/python/build_python.sh b/python/build_python.sh index 318bb13..90d32d7 100755 --- a/python/build_python.sh +++ b/python/build_python.sh @@ -13,9 +13,38 @@ # limitations under the License. # Build script for ProllyTree Python bindings +# +# Usage: +# ./build_python.sh # Build with default Python bindings +# ./build_python.sh --with-sql # Build with SQL support +# ./build_python.sh --all-features # Build with all features (Python + SQL) +# ./build_python.sh --features "python sql" # Specify features explicitly +# ./build_python.sh --install # Build and install the package +# ./build_python.sh --with-sql --install # Build with SQL and install set -e +# Show help if requested +if [[ "$1" == "--help" || "$1" == "-h" ]];
