1.7.2

Release Notes: Version 1.7.2

This release focuses on refactoring the SQLite module, particularly for Android, to improve code maintainability and streamline internal logic by leveraging the shared implementation of the QueryExecutor interface.

🛠 Refactorings & Improvements

• SQLite (Android) Optimization: Removed redundant overrides of execute and fetchAll from SQLite.Connection and SQLite.Transaction classes. These methods now correctly rely on the base implementation provided by the QueryExecutor interface.
• SQLite Result Set Handling: Enhanced the conversion logic from Android's Cursor to ResultSet. Improved handling of NULL values and provided more robust type mapping for common SQLite field types (Integer, Float, String, Blob).
• Code Cleanup: Removed unused imports and redundant internal functions in the sqlx4k-sqlite module for better performance and clarity.

1.6.0

Release Notes - Version 1.6.0

This release introduces significant improvements to connection pooling, enhanced native prepared statement support across all drivers, and more robust SQL parameter handling.

🚀 Features & Enhancements

• Enhanced Connection Pooling & Transactions:
  • Improved semaphore handling to prevent race conditions during connection acquisition.
  • Enhanced error safety and robustness when closing transactions.
• Native Prepared Statement Support:
  • Added full native prepared statement support for SQLite, MySQL, and PostgreSQL.
  • Expanded type handling within prepared statements, including support for byte parameters and longArray expansion.
• Typed Null Parameters:
  • Introduced TypedNull wrapper to allow specifying explicit type information for null parameters.
  • Added bindNull methods to the Statement API for both positional and named parameters.
• SQL Guards:
  • Added an EmptyCollection guard to prevent and gracefully handle empty list bindings in SQL statements.
• Refactored SQL Parsing:
  • Improved SQL parsing logic by extracting it into a reusable scanSql utility, ensuring more robust parameter detection and extraction.
• PostgreSQL Driver Optimizations:
  • Streamlined initialization logic and improved type cast handling for named parameters.
• PGMQ Updates:
  • Added lastReadAt property to Message to track read timestamps.
  • Switched MessageRowMapper to use column names for better reliability.

🛠 Bug Fixes

• Removed unnecessary exception handling in execute methods for MySQL and PostgreSQL drivers to allow for cleaner error propagation.
• Fixed an issue where empty named parameters in PostgreSQL were incorrectly handled during type casting.

📦 Dependency Updates

• Kotlin: Updated to 2.3.10.
• SQLite JDBC: Updated org.xerial:sqlite-jdbc from 3.51.1.0 to 3.51.2.0.

Release Notes for Version 1.5.16

This release focuses on significant internal refactoring of the Foreign Function Interface (FFI) layer, simplifying the project structure by removing redundant header files and modularizing dialect-specific logic.

🚀 Key Improvements & Refactoring

• FFI Layer Simplification:
  • Removed sqlx4k.h and its associated .def file in favor of a more streamlined native interop approach.
  • Simplified FFI logic within MultiplatformLibConventions to reduce build-logic complexity.
  • Modularized FFI logic across different database dialects (MySQL, PostgreSQL, SQLite).
• Unified Native Callbacks:
  • Implemented a unified fn callback system across all supported dialects, improving consistency in how native results are handled.
  • Refactored dialect-specific implementations (MySQL.kt, PostgreSQL.kt, SQLite.kt) to utilize the new modularized FFI structure.
• Code Quality & Maintenance:
  • Removed redundant imports and cleaned up unused native utility functions (DriverNativeUtils.kt).
  • Added auto-generated stubs for key structs like Ptr and Sqlx4kResult to ensure better type safety and interop stability.

🛠 Build & Infrastructure

• Updated MultiplatformLibConventions plugin to handle cinterop more dynamically based on the target platform and project name.
• Refined sqlx4k/build.gradle.kts to align with the new plugin structure.

  • Updated package names to sqlx4k.mysql, sqlx4k.postgresql, and sqlx4k.sqlite.
• Optimization: Updated Rust Cargo.toml to optimize release profiles (opt-level = 3, codegen-units = 1) and enabled dynamic linking for dialect-specific builds to prevent symbol duplication.
