Prebuilt kernel fallback: KernelBuilder::from_builtin_minimal() produces valid bzImage without Docker 5. Prebuilt eBPF fallback: EbpfCompiler::from_precompiled() produces valid BPF ELF without clang; Launcher::check_requirements()/dry_run() for QEMU detection README examples added to all 3 packages: - crates/rvf/README.md: Proof of Operations section - npm/packages/rvf/README.md: 7 real-world examples - npm/packages/ruvector/README.md: Working cognitive container examples 830 tests passing, workspace compiles cleanly.

Extract vector dimensions from column atttypmod instead of hardcoding 128, which caused corrupted indexes for non-128-dim embeddings (#171, #164) - Add page boundary checks in read_vector/read_neighbors to prevent segfaults on large tables with >100K rows (#164) - Use BinaryHeap::into_sorted_vec() for deterministic result ordering instead of into_iter() which yields arbitrary order (#171) - Handle non-kNN scans (COUNT, WHERE IS NOT NULL) gracefully by returning false from hnsw_gettuple when no ORDER BY operator is present (#152) Agent/SPARQL fixes: - Fix SQL type mismatch: ruvector_list_agents() and ruvector_find_agents_by_capability() now use RETURNS TABLE(...) matching the Rust TableIterator signatures instead of RETURNS SETOF jsonb (#167) - Add empty query validation to ruvector_sparql() and ruvector_sparql_json() to prevent panics on invalid input (#167) - Change workspace panic profile from "abort" to "unwind" so pgrx can convert Rust panics to PostgreSQL errors instead of killing the backend (#167) Security: - Bump lru dependency from 0.12 to 0.16 in ruvector-graph, ruvector-cli, and ruvLLM to resolve GHSA-xpfx-fvgv-hgqp Stacked Borrows violation (#148) Version bumps: workspace 2.0.3, ruvector-postgres 2.0.2 Co-Authored-By: claude-flow --- Cargo.toml | 4 +- crates/ruvector-cli/Cargo.toml | 2 +- crates/ruvector-graph/Cargo.toml | 2 +- crates/ruvector-postgres/Cargo.toml | 2 +- .../ruvector-postgres/sql/ruvector--2.0.0.sql | 4 +- .../ruvector-postgres/src/graph/operators.rs | 10 +++ crates/ruvector-postgres/src/index/hnsw_am.rs | 86 +++++++++++++++++-- examples/ruvLLM/Cargo.toml | 2 +- 8 files changed, 98 insertions(+), 14 deletions(-) diff --git a/Cargo.toml b/Cargo.toml index 8e860c176..1b433989a 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -99,7 +99,7 @@ members = [ resolver = "2" [workspace.package] -version = "2.0.2" +version = "2.0.3" edition = "2021" rust-version = "1.77" license = "MIT" @@ -171,7 +171,7 @@ opt-level = 3 lto = "fat" codegen-units = 1 strip = true -panic = "abort" +panic = "unwind" [profile.bench] inherits = "release" diff --git a/crates/ruvector-cli/Cargo.toml b/crates/ruvector-cli/Cargo.toml index 85f9d2ed2..fd17e4426 100644 --- a/crates/ruvector-cli/Cargo.toml +++ b/crates/ruvector-cli/Cargo.toml @@ -31,7 +31,7 @@ tokio-postgres = { version = "0.7", optional = true } deadpool-postgres = { version = "0.14", optional = true } # LRU cache for performance optimization -lru = "0.12" +lru = "0.16" # Compression for storage flate2 = "1.0" diff --git a/crates/ruvector-graph/Cargo.toml b/crates/ruvector-graph/Cargo.toml index 92bb24320..3fa13e2ca 100644 --- a/crates/ruvector-graph/Cargo.toml +++ b/crates/ruvector-graph/Cargo.toml @@ -69,7 +69,7 @@ pest_derive = { version = "2.7", optional = true } lalrpop-util = { version = "0.21", optional = true } # Cache -lru = "0.12" +lru = "0.16" moka = { version = "0.12", features = ["future"], optional = true } # Compression (for storage optimization, optional for WASM) diff --git a/crates/ruvector-postgres/Cargo.toml b/crates/ruvector-postgres/Cargo.toml index a49d8b84a..7506f822e 100644 --- a/crates/ruvector-postgres/Cargo.toml +++ b/crates/ruvector-postgres/Cargo.toml @@ -1,6 +1,6 @@ [package] name = "ruvector-postgres" -version = "2.0.1" +version = "2.0.2" edition = "2021" license = "MIT" description = "High-performance PostgreSQL vector database extension v2 -
