-c -> --checksum, -m -> --prune-empty-dirs, -M -> --remote-option,
-f -> --filter, -s -> --secluded-args, -p -> --perms, -T -> --temp-dir;
-a/--archive is now real rsync -rlptgoD (links+metadata+devices+specials).
FastSync's own flags moved to long-form-only or new shorts:
-j/--threads (multithreading), --preserve (metadata), --sendfile,
--chunk-serialization, --timeout, --ssh-port. Client-side only; the
wire config fields are unchanged (no PROTOCOL_VERSION bump). The server
keeps -p as its port. Docs (README, RSYNC_COMPAT summary 129->132) and
unit/integration tests updated. 37/37 unit, 400-pass integration.
- 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).
