Walkthrough

This pull request improves how the DuckDB appender handles errors and unsigned 32-bit integer appending. The changelog is updated to reflect enhanced error messages for both append_uint16 and append_uint32. In the C extension, the function for appending uint32 is renamed and its error handling is streamlined by converting the operation result to a boolean. In the Ruby layer, a new public method is added to wrap this functionality, raising an error if the append operation fails.

Changes

File	Summary
CHANGELOG.md	Updated error message handling documentation for DuckDB::Appender#append_uint16 and extended the fix to include DuckDB::Appender#append_uint32.
ext/duckdb/appender.c	Renamed appender_append_uint32 to appender__append_uint32, changed the method from public to private, and simplified error handling by directly returning a boolean value.
lib/duckdb/appender.rb	Added a new public method append_uint32 to the Appender class that calls the private _append_uint32 and raises an error if appending fails.

Poem

I'm a bouncy coder rabbit, hopping through the code,
uint32 appended smoothly now in our humble abode.
Private C functions work with finesse behind the scene,
Ruby calls them gently, keeping operations sleek and clean.
With refined messages to guide each step on my road,
I nibble on these changes—oh, what an efficient mode!

CHANGELOG.md (1)

9-9: Improved error message handling for uint32 append operations

The changelog entry correctly documents the fix for error message handling in DuckDB::Appender#append_uint16 and DuckDB::Appender#append_uint32.

lib/duckdb/appender.rb (1)

247-266: LGTM! Good implementation of append_uint32

The implementation follows the established pattern used by other append methods in the class. It correctly calls the private _append_uint32 method and raises an appropriate error message if the operation fails.

Note that following the pattern from the retrieved learning about append_uint8, this method doesn't perform range checking for uint32 values (0 to 4,294,967,295), which maintains consistency with the library's design philosophy.

ext/duckdb/appender.c (3)

17-17: Naming convention aligned with other private methods

Good change to rename the function to follow the established pattern of using double underscore prefix for private methods.

---

190-198: Improved error handling consistency for append_uint32

The simplified error handling approach that directly returns the boolean result of the operation is consistent with how other similar methods work in this file. This improves overall code consistency and maintainability.

---

441-441: Method correctly moved to private API

Good change to register the method as private using rb_define_private_method, which aligns with the overall architecture where the Ruby wrapper (append_uint32) provides the public API that uses this private implementation.
