- Replace --dist=loadgroup (a no-op: it only groups by xdist_group marks) with
--dist=load, and make module teardowns remove only their own SOURCE_DIR/DEST_DIR
(never the shared worker-keyed TEST_DATA_DIR) so interleaved modules can't wipe
each other's fixtures. Add a session-scoped cleanup of the per-worker dir.
(loadfile grouped the whole test_features.py module onto one worker and slowed
the full suite to 761s vs 224s with load.)
- Mark the two setpriv privilege tests with a 'setpriv' marker and run the full
merge suite as -m "not setpriv", so the dev/main gate can't go red on the
env-dependent /root-traversal tests regardless of the runner uid.
- Add a TLS basic test to the ci subset, add workflow_dispatch for on-demand full
runs, and fix trailing newlines.
- Measured: smoke -m ci = 28 passed/39s; full -n4 = 280 passed/11 skipped/1 xpassed
in 224s (was 860s serial).
- Add pytest-xdist to the CI Dockerfile (image -> v10).
- Worker-isolate TEST_DATA_DIR (PYTEST_XDIST_WORKER) so concurrent xdist
workers never collide on shared-filesystem fixtures.
- Register a 'ci' marker and tag a fast representative subset of integration
tests (basic TCP, incremental, compression, delete, basis, append).
- ci.yaml: lint + build + unit + the marked subset (-n4) on every PR; the
full integration suite plus sanitizer/fuzz/coverage/valgrind run only on
push to dev/main.
- Integration step runtime drops from ~860s (serial) to ~230s (-n4); the PR
gate lands well under ~3 minutes.
