What's New in v0.3.4

Complete C API for embedding Stoolap in any language that can call C functions. Feature-gated with --features ffi.

Opaque handle API with step-based iteration, per-handle error storage, and panic-safe catch_unwind boundaries
Bulk fetch API (stoolap_rows_fetch_all) transfers entire result sets in a single packed binary buffer, eliminating per-row FFI overhead
Prepared statements with pre-compiled plans that bypass cache lookup on every execution
Transaction support with isolation level control (begin, commit, rollback)
Parameter binding for both positional ($1, $2) and named (:key) parameters
Full C header (include/stoolap.h) with documented binary format spec

:::c StoolapDb *db = stoolap_open(":memory:"); stoolap_exec(db, "CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT)");

StoolapStmt *stmt = stoolap_prepare(db, "INSERT INTO users VALUES ($1, $2)"); StoolapValue params[] = { stoolap_int(1), stoolap_text("Alice") }; stoolap_stmt_execute(stmt, params, 2);

GENERATE_SERIES for integer, float, and timestamp types
LIMIT pushdown, WHERE range clamping, JOIN support, and EXPLAIN integration
TVF infrastructure (parser, AST, executor, registry) for future functions

:::sql SELECT * FROM GENERATE_SERIES(1, 10); SELECT * FROM GENERATE_SERIES('2026-01-01', '2026-12-31', '1 month'); SELECT g.value, t.name FROM GENERATE_SERIES(1, 5) g JOIN tasks t ON t.id = g.value;

Mixed OR hybrid optimization for queries with both indexed and non-indexed OR branches (index lookup + filtered scan with dedup)
Relaxed multi-column index prefix rule to allow single-column prefix matching
Trailing range scan on composite indexes after equality prefix
BETWEEN decomposition to range comparisons for index use
Subquery index probe safety guard with outer refs or nested subqueries
Aggregation guard to prevent fast-path optimizations on aggregate queries

Documentation page with features overview, installation guide, quick tour, and keyboard shortcuts
Responsive dark/light mode screenshots on docs site and README

Fix undefined behavior in FFI bulk fetch buffer deallocation: into_boxed_slice() guarantees len == capacity for safe Vec::from_raw_parts reconstruction
Fix CowHashMap Stacked Borrows violation in drop and backward-shift deletion
Fix I64Map Stacked Borrows violation in backward-shift deletion
Fix CowBTree Stacked Borrows violations across all node pointer accesses
Fix CompactArc Stacked Borrows violation: derive data pointer via raw arithmetic instead of Deref
Restore Expression::Case match arm in process_where_subqueries accidentally deleted by mutation testing
Fix qualified outer column resolution in expression compiler to prevent incorrect binding when inner row shadows outer column names
Fix parser handling of consecutive semicolons (SELECT 1;;)
Reject bare expression statements in prepare() to catch typos like SELECTX at prepare time

14 FFI aggregate function tests (COUNT, SUM, AVG, MIN, MAX, GROUP BY, HAVING, JOINs, subqueries)
67 unit tests for outer reference detection covering all match arms
13 integration tests for correlated subquery outer reference paths
MVCC TransactionRegistry unit tests
sqllogictest suite with comprehensive .slt test files
Failpoint infrastructure for I/O error injection testing
Nightly CI: mutation testing (24 shards), Miri rotation (5 module groups), stress tests, sanitizers
TSAN inline suppression for CompactArc false positive
