gix-parallel v0.50.0

on GitHub

Changed (BREAKING)

• centralize plumbing thread-safety configuration

  Plumbing crates share the threading primitives and algorithms selected by
  gix-parallel/parallel. Their forwarding-only parallel features duplicate
  that switch and obscure Cargo's feature unification. Remove those features
  from gix-attributes, gix-filter, gix-index, gix-odb, gix-pathspec,
  gix-ref, gix-status, gix-worktree, and gix-worktree-state.

  Breaking change: callers using the removed features must enable
  gix-parallel/parallel directly. Keep gix/parallel as the porcelain switch,
  forwarding to gix-parallel/parallel and the distinct gix-pack/parallel.

  Tree streaming always spawns a producer thread, so gix-worktree-stream
  enables gix-parallel/parallel directly and documents its effect on other
  crates through feature unification. Make gix/worktree-stream also enable
  gix/parallel, including through worktree-archive, so locally gated code
  and shared thread-safe types agree. Likewise, select thread-safe types for
  gix-testtools' shared fixture-exclusion cache explicitly.

  Move thread-safety assertions and the object-database concurrency regression
  into test targets requiring gix-parallel/parallel. Collect worker handles
  before releasing the barrier and use at least two workers, ensuring the
  regression actually exercises concurrent access. Replace the reference-store
  fixture with a direct Send + Sync assertion.

  Avoid enabling parallelism indirectly through test-helper defaults where
  serial coverage is intended. Update just unit-tests to exercise serial
  plumbing and explicitly selected threaded targets, including SHA-256 object
  lookup coverage, and remove the unused worktree forwarding dependency.

  Also replace the disconnected-branch ASCII graph snapshot with a
  git rev-list disjoint --not main comparison. This retains Git reference
  coverage without depending on version-specific graph layout.

Other (BREAKING)

• specialize gix-features for parallel execution

  The gix-parallel crate is mostly copy-paste from gix-features, but
  most tests are newly generated.

  gix-features once coordinated several alternative implementations.
  Serial versus threaded execution is its remaining shared implementation
  policy; tracing, hashing, compression, and filesystem operations already
  have their own owners.

  Move progress, interruption, byte pipes, decoding, iterator chunks, and
  cache diagnostics into gix-utils. Keep utilities that add dependencies
  behind feature toggles, including interrupt for typed cancellation via
  gix-error. Use crc32fast directly in gix-pack and gix-odb.

  Rename the remaining crate to gix-parallel and expose its computation
  helpers, reducers, and shared ownership primitives at the crate root.
  Replace gix::features and gix::threading with the existing owner exports,
  including gix::parallel and gix::utils, and adapt all workspace callers.

  Expose both progress formatting choices individually on gix, retaining
  comfort as their bundle. Forward tracing directly to gix-trace and
  cache diagnostics to gix-utils. Update documentation, feature checks,
  the pack fuzz harness, and package-size checks for the new ownership.
