Summary

  • Enable Alpine Linux in parallel::is_enabled — prior race conditions were resolved by later parallel hardening (8c7212d and follow-ups).
  • Add unit test test_parallel_enabled_on_alpine and extend existing tests to mock is_alpine.
  • Add Alpine CI matrix with parallel simple and parallel extended jobs so regressions surface immediately.

Test plan

  • ./bashunit tests/unit/parallel_test.sh — all green
  • ./bashunit --parallel tests/ on macOS — all green
  • Alpine Docker --parallel --simple tests/unit/ — 694 passed, 0 failed (9s vs 32s sequential; 3.5x speedup)
  • Alpine Docker --parallel tests/ — 926 passed, 0 failed (exit 0)
  • make sa && make lint pass
  • shfmt -d clean

Closes#370

fix(parallel): enable parallel test execution on Alpine Linux
ca892e3
Previous race conditions on Alpine were resolved by later parallel
hardening work (8c7212d and follow-ups). Enable Alpine in
`parallel::is_enabled`, update unit coverage, and add matrix CI jobs
running `--parallel --simple` and `--parallel` against the Alpine
container so regressions surface immediately.

fix(ci): drop coreutils from alpine job to match previous baseline
77d135b
Busybox stat already supports `-c`, so installing coreutils is not
required. Removing it also avoids exposing 7 extra acceptance tests
that rely on a GNU environment and were previously skipped under
busybox, which caused the upgrade test to break on Alpine CI.

Summary
  • Enable Alpine Linux in parallel::is_enabled — prior race conditions were resolved by later parallel hardening (8c7212d and follow-ups).
  • Add unit test test_parallel_enabled_on_alpine and extend existing tests to mock is_alpine.
  • Add Alpine CI matrix with parallel simple and parallel extended jobs so regressions surface immediately.
Test plan
  • ./bashunit tests/unit/parallel_test.sh — all green
  • ./bashunit --parallel tests/ on macOS — all green
  •  Alpine Docker --parallel --simple tests/unit/ — 694 passed, 0 failed (9s vs 32s sequential; 3.5x speedup)
  •  Alpine Docker --parallel tests/ — 926 passed, 0 failed (exit 0)
  • make sa && make lint pass
  • shfmt -d clean
Closes#370

fix(parallel): enable parallel test execution on Alpine Linux
ca892e3
Previous race conditions on Alpine were resolved by later parallel
hardening work (8c7212d and follow-ups). Enable Alpine in
`parallel::is_enabled`, update unit coverage, and add matrix CI jobs
running `--parallel --simple` and `--parallel` against the Alpine
container so regressions surface immediately.
Closes#370

fix(ci): drop coreutils from alpine job to match previous baseline
77d135b
Busybox stat already supports `-c`, so installing coreutils is not
required. Removing it also avoids exposing 7 extra acceptance tests
that rely on a GNU environment and were previously skipped under
busybox, which caused the upgrade test to break on Alpine CI.
