polyglotSQL 0.1.2

Lighter Rust release profile (opt-level = "s", no LTO, 16 codegen units) to cut the cost of building from source: about half the compile time and roughly a quarter less peak memory for the largest crate. This targets the CRAN macOS x86_64 builders, which stopped the installation at their 30-minute limit, and the linux-arm64 check, where the compiler ran out of memory. On macOS and Linux the shared library now exports only its R entry point and leaves out local symbols, which keeps the installed size at the level of 0.1.1. The R API and results are unchanged.
On Linux and macOS the shared object no longer references the C library’s abort(). The Rust standard library calls it as a last resort (a failed memory allocation, a panic raised while another panic is being handled); those calls are now redirected at link time to a function that raises an R error instead, so compiled code can never terminate the R session. This removes the Found 'abort' NOTE of the CRAN linux-arm64 check. Ordinary Rust panics were already caught and turned into R errors.

polyglotSQL 0.1.1

Updated the embedded polyglot-sql engine from 0.6.2 to 0.12.0 (upstream changelog: https://github.com/tobilg/polyglot/blob/main/CHANGELOG.md). Highlights inherited by the R API: parser-depth protection enabled by default (deeply nested SQL now raises a polyglot_guard_error instead of risking a stack overflow); grouping, aggregate and window placement errors in semantic validation (E230-E232); sql_analyze() now reports scoped non-projection columnUses and propagates nullability and cast types through CTEs and derived tables; NULLS FIRST/NULLS LAST are preserved when formatting; 128-bit and unsigned integer types; name-aligned UNION BY NAME handling; many dialect fixes (DuckDB, Snowflake, ClickHouse, BigQuery, T-SQL).
sql_validate(semantic = TRUE) now also reports semantic correctness errors E230-E232 (ungrouped columns, misplaced aggregates and window functions), which invalidate the statement; quality hints remain warnings. Default syntax-only validation is unchanged.
Errors of the new upstream kinds invalid_input and column_resolution are surfaced as plain polyglot_error conditions.
macOS: the Rust build now uses the deployment target of R’s C compiler (including a -mmacos-version-min flag set in CC) instead of the version of the running system. This removes the ld warning “object file was built for newer ‘macOS’ version than being linked” seen in the CRAN M1mac checks.

Initial release, wrapping the polyglot-sql Rust crate 0.6.2.

Core: polyglot_version(), sql_dialects() (34 dialects with aliases).
Transpilation and formatting: sql_transpile(), sql_format(), sql_generate() with complexity guards and configurable handling of unsupported constructs.
Parsing and validation: sql_parse(), sql_tokenize(), sql_validate() (strict syntax, semantic warnings, schema-aware checks).
Analysis and lineage: sql_source_tables(), sql_lineage(), sql_analyze(), sql_optimize(), sql_diff(), sql_annotate_types(), sql_openlineage().
Classed error conditions (polyglot_error, polyglot_parse_error, polyglot_transpile_error, polyglot_validation_error, polyglot_guard_error, …); Rust failures never crash the R session.
Fully offline source builds via vendored crates (cargo vendor).
