sdk%feat: extend `TypeId` to support arguments, harden CodeQL lockfile enforcement, drop all dependencies from `dash-pow`, minor cleanups and doc fixes by kwvg · Pull Request #27 · dashpay/base-sdk

kwvg · 2026-08-16T20:44:52Z

Motivation

base-sdk#22 and base-sdk#25 introduced types that take in type arguments (BlsScheme), which revealed a limitation in the way TypeId was implemented, since it didn't have a concept of arguments, which had to be worked around then by manually computing the xxHash32 of a good-enough identifier and in some cases, sharing it.

Sharing TypeIds goes against the point of having an identifier to distinguish between types to identify what the following bytes encode. At the time, it was considered fine since the operational types were using dlgt_codec! to the bag byte so their wire layout should be identical but tracking all dlgt_codec! uses and whether a reused TypeId is "valid" is just asking for problems in the future.

So, this pull request gets rid of that altogether by implementing type argument support and dropping the old hardcoded IDs and prohibiting manual derives (the method used to supply custom IDs) as the current collision detection code in dash-dev doesn't factor that in.

Additionally, in preparation for future pull requests which offer binds to some base-sdk crates, this pull request also prunes the dependencies required by dash-pow and other crates to shave off the dependency tree for that specific crate. Later pull requests will further work to segment and prune the dependency tree so that FFI bind crates only include code paths that are actually interfacable.

Additional Information

The emitted impl now carries a synthesized where clause adding P: TypeId for every type parameter, on top of whatever predicates the type already declared.
derive(TypeId) now rejects two shapes at compile time
- const parameters, as all instantiations would share the same ID.
- Type parameters whose only bound is TypeId, unbounded types stuff the table and increase collision risk due to sheer volume, TypeId is meant for types that have a plausible wire representation.

Two paths were escaping the CodeQL pack lockfile

codeql database create could pull GitHub's default query pack
The bare suite reference codeql/rust-queries:codeql-suites/${name}.qls resolves to the latest version.

Because of this, we encountered failures when running CodeQL locally (see below). This has since been resolved.

Breaking Changes

dash_pow::hash returns [u8; 32] instead of dash_num::Hash256. Callers intending to preserve the newtype must construct it manually (e.g. Hash256::from(dash_pow::hash(&buf))).
TypeId has moved from dash_types::codec::TypeId to dash_types::type_id::TypeId and the TypeId and Unencodable derive macro re-exports have moved from the dash_types crate root to dash_types::type_id.

Removed

dash_pkc::worker::{par_verify, par_map, par_reduce, init}
dash_pkc::bls::schemes::BlsSchemeId::{PK_TYPE_ID, SK_TYPE_ID, SIG_TYPE_ID}
dash_pow::worker::{par_hash, init}

📝 Walkthrough

Walkthrough

Changes

The change centralizes TypeId support, adds generic collision scanning, changes proof-of-work APIs to byte arrays, removes Rayon-based worker modules, updates BLS fixtures, and revises dependency and static-analysis configuration.

TypeId infrastructure

Layer / File(s)	Summary
TypeId contract and generic derivation `pkgs/types/`, `pkgs/types/marker/`	Adds the public `type_id` module, order-sensitive ID mixing, generic derive support, and related tests.
Build-time collision scanning `pkgs/dev/*`	Scans generic derives and trait implementations, expands valid parameter combinations, and checks ID collisions.
TypeId adoption `pkgs/pkc/src/bls/`, `pkgs/p2p_core/`, `pkgs/primitives/`, `pkgs/script/`, `pkgs/num/*`	Moves imports to `type_id` and replaces manual BLS TypeId implementations with derives.
BLS test fixtures `pkgs/pkc/src/bls/*`	Uses shared `RSEED` and message fixtures and adds `MSG_8BADFOOD`.

Proof-of-work API

Layer / File(s)	Summary
Hash output conversion `pkgs/pow/src/*`	Hash functions return `[u8; 64]`, and the top-level hash function returns `[u8; 32]`.
Utilities and validation `pkgs/pow/src/util/`, `pkgs/pow/tests/`, `contrib/samples/solver/solver.rs`	Hex helpers, tests, and the solver use raw arrays or convert them to `Hash256` where required.
Parallel worker removal `pkgs/pow/bench/*`, `pkgs/pow/src/worker.rs`, `pkgs/pkc/src/worker.rs`	Removes parallel hashing and verification workers and their benchmarks.

Tooling and configuration

Layer / File(s)	Summary
Dependency wiring `pkgs/*/Cargo.toml`, `README.md`	Updates crate features, removes obsolete dependencies, and renames the documented `k256` feature to `ecdsa`.
Static analysis `contrib/codeql/*`, `contrib/lint/lint_codeql.py`, `contrib/semgrep/workspace.yml`	Pins CodeQL suite resolution and adds detection for manual TypeId implementations.
Documentation graph `README.md`, `docs/zen/index.md`	Shares the crate dependency graph through a README snippet with updated Mermaid configuration.

Walkthrough

The codebase now defines TypeId in dash_types::type_id, derives IDs for generic types, and validates collisions during the development build. Proof-of-work functions return fixed-size byte arrays. Rayon worker support and related benchmarks were removed. Dependency, documentation, CodeQL, and Semgrep configuration were updated.

Inline comments:
In `@contrib/semgrep/workspace.yml`:
- Line 236: Update the TypeId alias detection regex in the pattern-regex rule to
accept underscore-prefixed aliases as well as regular Rust identifiers after as.
Add a regression fixture covering a use path::TypeId as _TypeId declaration and
a macro-generated impl _TypeId case.
- Around line 234-235: Update the TypeId implementation detection rule around
the existing pattern-regex so it token-awarely finds impl tokens inside one-line
macro_rules! bodies, including after an opening brace, while excluding comments
and string contents; preserve the existing exclusions and add a regression
fixture covering this macro case.
- Around line 231-232: Update the structural pattern for the TYPE_ID
implementation in the relevant Semgrep ERROR rule to require the trait being
implemented is TypeId, while retaining the existing regex branch for qualified
TypeId paths. Add a negative fixture covering an unrelated trait with a TYPE_ID
constant and verify it is not reported.

In `@pkgs/dev/build.rs`:
- Around line 116-130: Update implementors so each candidate type is included
only when it appears in plain and has an implementation for every non-TypeId
trait in bounds, rather than matching any single bound. Preserve the existing
sorting and deduplication behavior.

In `@pkgs/pkc/src/bls/schemes.rs`:
- Around line 9-12: The BlsSchemeId change must preserve the public API and
existing TypeId constants: retain PK_TYPE_ID, SK_TYPE_ID, and SIG_TYPE_ID for
external implementors and consumers, and ensure existing BLS scheme identifiers
such as BlsPkBytes remain unchanged. Avoid deriving replacement IDs unless the
full breaking migration is explicitly implemented.

In `@pkgs/pow/Cargo.toml`:
- Around line 9-13: Remove the stale optional rayon dependency from the package
manifest and eliminate any implicit or explicit rayon feature, including
references used by all-features resolution. Preserve the existing std, full,
aes_hw, and simd feature definitions.

In `@pkgs/script/Cargo.toml`:
- Line 22: Update the dash-pkc dependency declaration to explicitly enable the
ecdsa feature while retaining default-features = false, so the unconditional
dash_pkc::ecdsa::EcdsaPkBytes usage in addrs.rs remains available.
