Some of our tests look for the number of CPU's in the environment they're running on and then split the tests to run in parallel. We could do that for xt/perltidy.t too and save time when running those tests locally.
Created attachment 189714 [details] [review] Bug 41273: Parallelize test execution for improved performance This patch adds parallel processing to xt/perltidy.t using Parallel::ForkManager, following the same pattern as xt/pl_valid.t and xt/tt_tidy.t. Changes: - Uses Parallel::ForkManager to process files concurrently - Auto-detects CPU count via Sys::CPU (respects KOHA_PROVE_CPUS env var) - Preserves working directory context in forked child processes - Maintains correct failure tracking in %results hash Performance improvement: ~N× speedup on N-core systems (e.g., 8× faster on 8-core, 16× faster on 16-core machines) Test plan: 1. Clear incremental test cache (if needed): docker exec kohadev-koha bash -c 'rm -rf /tmp/koha-ci-results/perltidy*' 2. Run test: docker exec kohadev-koha bash -c 'KOHA_PROVE_CPUS=8 prove xt/perltidy.t' 3. Verify all 3138 tests pass 4. Verify test completes significantly faster than before
