feat(threads): implement phases 17 through 20 - #931
Merged
Conversation
Implement platform-thread ownership, runtime-family IDs, parent relationships, completion and error capture, one-shot join/detach transitions, and registry cleanup. Runtime snapshots created for managed threads retain the family registry without exposing the Perl threads API or changing Config flags. See dev/design/concurrency.md Phase 17.

Replace the detached harness stub with working create/new/async, identity, listing, state, join, detach, yield, and equality operations. The thread entry CODE reference and arguments share the runtime snapshot identity map; return values cross back through a new graph clone in the caller's context. Keep Config thread capability flags disabled until the activation phase. See dev/design/concurrency.md Phase 18.

Add a dedicated thread-exit unwind, retain uncaught errors for error(), run child-owned END queues before completion, support nested thread ownership, and clean joined or detached registry entries without unsafe Java thread stopping. Materialize lazy named subs before snapshots so child API calls do not retain parent-only compiler suppliers. The kill API remains an explicit no-op until a safe compatible mechanism is defined. See dev/design/concurrency.md Phase 19. Generated with [Codex](https://openai.com/codex) Co-Authored-By: Codex <223018245+openai-codex[bot]@users.noreply.github.com>
Implement threads::shared share, is_shared, and shared_clone plus real :shared attribute handling for scalar, array, and hash storage. Shared nodes retain identity across ithread graph clones, aggregates use synchronized backing collections, and scalar payloads provide cross-thread visibility. Reject blessed and tied storage in this first tranche; locks and condition variables remain Phase 21. Update the living design and attribute reference. See dev/design/concurrency.md Phase 20.

Rebase the phase 17-20 train onto the runtime fixes merged in PRs 927 and 930, then repair the remaining thread activation regressions. Keep lazy named subroutines lazy across runtime snapshots while rebinding their compiler suppliers to the source runtime and cloning the completed definition into the child. Avoid BEGIN-time compiler-lock deadlocks by retaining the detached stub boundary until ithreads are advertised. Also reject directory-only classpath resources from require, restoring the RT #24404 behavior after adding the threads/shared.pm resource directory.
