refactor(catalog): share Glue table lookup between get_table and has_table

test(sql): check ADBC writes with independent reads Read the written tables back with Python's sqlite3 module and a direct SQLAlchemy query, and check stored column types and NULLs, so Daft's own read path can't hide a write mistake.

fix(sql): address review on ADBC reads - Drop SQLAlchemy-only SQLite URL options (e.g. timeout) instead of passing them into the ADBC filename, and keep SQLite URI options such as mode=ro on a file: URI. - Honour backend="connectorx" for queries with a schema (the MIN/MAX partition bounds query) and cast the result, instead of falling back to SQLAlchemy. - Move the sys import in tests to the top of the file.

fix(iceberg): match the spec for decimal bucket, string truncate and pre-1970 hour transforms (#7649) ## Changes Made Three Iceberg partition transforms diverged from the spec, so Daft wrote rows to the wrong partitions and pruned away matching files in tables written by other engines: - `bucket` on decimals now hashes the minimal two's-complement bytes with room for the sign bit, as Java's `BigInteger.toByteArray()`. Negatives, zero, and values like `1.28` were hashed wrongly. - `truncate` on strings counts code points (`substring_by_char`) instead of bytes, which failed on non-ASCII values. - `hour` uses floor division, so timestamps before 1970 map to negative hours. `test_partitioning_hours` asserted the old truncating results; it now expects the spec values, which PyIceberg also returns. The Rust decimal hash test computed its expectation with the same algorithm as the code under test; it now checks fixed byte encodings. ## Related Issues Closes #7648 ## AI Disclosure AI-assisted implementation.

fix(sql): normalize SQL function names at registration (#7449) ## Changes Made The SQL IOConfig constructors were unreachable under every spelling: ```python daft.sql("SELECT * FROM read_parquet('f.parquet', io_config := S3Config(region_name => 'us-west-2'))") # Function `s3config` not found ``` `modules::config` registers `S3Config`, `HTTPConfig`, `AzureConfig`, `GCSConfig` and `TosConfig` in mixed case, but lookup lowercases the name before the `HashMap` get. `add_fn` now lowercases the key. Other modules already register lowercase names, so only these five keys change (`list_sql_functions()` shows `s3config`). Once reachable, `HTTPConfig` still rejected four of its six documented arguments: `parse_function_args` whitelisted only `user_agent` and `bearer_token`, while `retry_initial_backoff_ms`, `connect_timeout_ms`, `read_timeout_ms` and `num_tries` are read and advertised. The whitelist now matches. ## Testing Parametrized over `S3Config`/`s3config`/`S3CONFIG`, plus one `HTTPConfig` case per retry/timeout argument; each asserts the value reaches the plan's IO config and fails on `main`. native `tests/sql` 452 passed, new cases pass on ray, pre-commit clean. ## AI usage disclosure Written with an AI coding assistant. I reviewed the full diff and confirmed the tests fail without the fix. ## Related Issues Closes #7447. The `default_io_config` fallback is #7551.

fix(paimon): read catalog options from pypaimon Options objects (#7667) Fixes #7653 ### Root cause `read_paimon` read `table.file_io.properties` as a dict (`catalog_options.get("warehouse", "")`). Since pypaimon 1.4.1 that attribute is an `Options` object whose `get` takes a `ConfigOption`, so every read raised `AttributeError: 'str' object has no attribute 'key'`. ### Fix New helper `_get_catalog_options(table)` returns a plain dict, going through `Options.to_map()` when present and still accepting a dict (older pypaimon) or a missing `file_io`. `read_paimon` uses it for both the IO config inference and the `warehouse` passed to the scan. ### Test `test_get_catalog_options_accepts_options_object` covers an `Options`-like object, a plain dict, `None` and a missing `file_io`. The end-to-end `read_paimon` tests in `tests/io/paimon` run in CI against the pinned `pypaimon==1.3.1`, so they keep covering the dict path but do not reach the `Options` path; the new unit test is what covers it. ### Disclosure This change was prepared with the assistance of Claude, an AI coding agent. The helper's logic was exercised in isolation; the full paimon test suite was not run for this change. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Sonnet 5.5 <noreply@anthropic.com>
