New `sched_apply_job_rusage()` (schedobj.c) stores the report ON the job (ownership transferred), replacing any prior via the generated `free_JobRusages_ptr`; returns `-ENOENT` unknown / `-EINVAL` NULL. The dequeue `JOB_RUSAGE` case calls it and NULLs `req->u.job_rusage.rusages` on success so the killer doesn't double-free; `kill_sched_job` (was a no-op stub) now releases `job->rusages`. NOTE: used the generated capnp deep-freer `free_JobRusages_ptr` (NOT a hand-rolled freer — it correctly frees pids/pgids/usages incl. resname per the capnp allocation model; an earlier hand-rolled `free_job_rusages` was removed). 4 new white-box tests (store / replace-frees-prior / -ENOENT / -EINVAL): sched_job_update_test 7/7. - 5.8 (bug-765 remediation, gap G-3, done 2026-06-18): `sched_pend_update_killer` now frees all five previously-leaked op payloads with the exact generated deep-freers — `free_QueueConf_ptr` (xce_queue_t), `free_Resource_ptr[]`+free(arr) (xce_resource_t), `free_ResourceVal_ptr[]`+free(arr) (xce_resval_t), `free_ResValList_ptr` (xce_resval_list_t), `free_JobRusages_ptr` (xce_job_rusages_t). Safe because: ownership is transferred (notify `sched_handle_notify` and dataset `sched_handle_dataset` nullify their pointers on enqueue), `makeResource` constructs a fresh instance via `makeInstance` (no alias), and the dequeue copies values (no alias). VERIFY NOTE: the JOB_RUSAGE killer path interacts with 5.5's ownership; the other four killer frees are review-verified (type-exact generated freers + confirmed transfer/non-alias) but NOT runtime-ASAN-exercised — those notify/dataset ops are not emitted to the scheduler in production today (research R-3 dormant paths) and constructing capnp payloads for a dequeue test is a follow-up. regression sched_test 15/15; no bad-free/double-free under ASAN. - G-7 (bug-765 doc drift, resolved 2026-06-18, DOC-ONLY): the scheduler-op name lookup is `static sched_op_name(xce_sched_op_t)` in `scheduler.c`, NOT `xce_sched_op_name` in `lib/helper`. RESOLUTION = fix the docs (code is correct): `xce_sched_op_t` is a scheduler-only type (`scheduler.h`) and `src/lib` has zero scheduler-header dependencies, so placing the helper in lib/helper would be a layering inversion. Only `xce_notify_event_name(int)` (lib-level) belongs in lib/helper. Updated Task 1 (intro + 1.1/1.3 + 5.7 + 9.1) and design.md Component 8/9 + file table + risks to reflect the scheduler-layer placement. No code change (kept `sched_op_name` in origin per user direction). +- G-6 (bug-765 test debt, addressed 2026-06-18): converted the falsely-`[x]` Task 9 tests into REAL tests via two new white-box executables (registered as meson tests under `--suite scheduler`, leaks-off per convention): `testsuite/test_handlers.c` (`#include "../src/handler.c"`; `enq_pend_update` + handlers are static → self-contained, only `sched_init_config` stubbed) covers 9.2 + 9.3 (6 tests); `testsuite/test_job_update.c` (`#include "../src/schedobj.c"`) covers 9.4 (job in-place), 9.5 (queue in-place — replaces the old local-stub test), 9.7 (rusage) — 10 tests. Suite: sched_test 15/15 + sched_job_update_test 10/10 + sched_handlers_test 6/6, all GREEN, ASAN-clean. REMAINING (honest): 9.6 dequeue worker-resvals APPLY is PARTIAL — enqueue tested, apply is a dormant path (R-3); 9.8 is a documented compile-time symbol-absence guarantee; 9.9 stays gated (log-capture infra); 9.2 `-ENOMEM` calloc-fault path not injected. These are low-value/dormant; the correctness-critical handler + applier paths are now genuinely covered. diff --git a/src/scheduler/testsuite/meson.build b/src/scheduler/testsuite/meson.build index 87bc722a..c438d630 100644 --- a/src/scheduler/testsuite/meson.build +++ b/src/scheduler/testsuite/meson.build @@ -20,3 +20,21 @@ sched_job_update_test = executable('sched_job_update_test', include_directories:[incdir], dependencies: [scheduler_test_deps], install: false) + +# White-box test for the notify/dataset enqueue handlers.
