A few choices stand out as thoughtful: + +- **Hierarchical layer model** (moments → vlasov → gyrokinetic → pkpm) with + per-layer SQLite DBs and uniform Lua/C discovery. Clean and scales. +- **On-the-fly C compilation** from the installed `share/Makefile`, with a local + `rt_arg_parse.h` overriding the installed copy, removes a whole + `make regression` step. +- **Cost-ordered scheduling** (cheapest-first) to shorten makespan under + `--jobs N`, with a robust cross-platform timeout layer: GNU `timeout` → + `gtimeout` → a Perl fork + `setpgrp` + `alarm` fallback that correctly kills + the entire process group (so a grandchild `gkeyll` launched by `sh` is reached). +- **Combined abs-AND-rel tolerance** in `compareFiles` — the correct way to + avoid false failures both near zero (tiny abs, huge rel) and at large + magnitudes (large abs, tiny rel). +- **Walking the *accepted* directory** (not the run dir) in `check_action`, so a + test that crashes before writing its last frame is flagged as missing rather + than silently skipped. A subtle, correct choice. + +## Issues — most serious first + +### 1. The step-cap mechanism has quietly turned the suite into a smoke test + +The numbers tell the story. Of 554 tracked tests in `test_costs.lua`: + +| num_steps cap | tests | +|--------------:|------:| +| 10 | 445 | +| 3 | 74 | +| 1 | 1 | +| 0 | 33 | + +So by default `run check` exercises essentially *no* time evolution. A bug that +manifests at step 500 — instability, slow drift, boundary accumulation, +conservation violation — cannot be caught. The accepted baselines are *also* +created under the same cap (`create` flows through `stepArgFor` too), so a +10-step state is compared against a 10-step baseline. + +This is a legitimate "make it run in 5 minutes" tradeoff (recent commits show +that was the explicit goal), but it is currently **invisible**: nothing in the +run summary says "this suite covers a median of 10 steps," and a reader would +reasonably assume `check` tests the physics. The coverage reduction lives in an +auto-generated file, not in the tests. + +### 2. `num_steps = 0` converts crashing tests into passing tests + +33 tests are pinned to `-s 0`. The code comment is explicit (runregression.lua +lines 469–479): a sim that aborts on its first step records 0, then runs zero +steps "so the test exits cleanly instead of failing." That means a test that +*crashes* is recorded as **green**: it compares initialization-only output +against an initialization-only baseline and reports pass. + +Most of these are `rt_gr_*` / `rt_vacuum_einstein_*` / `rt_mhd_ot` — exactly the +family flagged as still broken (`gr-moments-uninit-bugs`). This is a +reward-hacking-shaped hole: the harness reports health it does not have. At +minimum these should carry a distinct status (`SKIP-CRASHES` / xfail) and must +never be counted as `pass`. + +### 3. No process exit code reflects test failure + +Every `os.exit(1)` in the file is a config/parse error path. `run_action` +returns normally whether 0 or 500 tests fail. There is no +`os.exit(nfail > 0 and 1 or 0)`. For a regression harness this is the single +biggest *automation* gap — CI cannot gate on it without scraping the log or +querying SQLite. One-line fix, outsized value. + +### 4. Unit-test runners can false-pass and record nothing + +`runLuaUnitTest` / `runCxxUnitTest` only `log` PASS/FAIL — no DB row, no counter, +no exit code. Worse, `runCxxUnitTest` greps stdout for `"FAILED"`: a binary that +**segfaults and prints nothing** is treated as passed. `runLuaUnitTest` keys on +the substring `"PASSED"` with the same fragility. `rununit` therefore cannot +gate anything and can hide crashes. + +### 5. Unreadable output silently passes + +In `compareFiles`, when `arrayNewFromFile` fails it returns `true` ("skipping … +unsupported file format"). A `.gkyl` file that cannot be read counts as a pass. +A corrupt or truncated output should fail, not be waved through. + +### 6. Committed millisecond costs cause churn and aren't portable + +`test_costs.lua` conflates two very different things: + +- **`num_steps`** — genuine test configuration; belongs in the repo. +- **`cost`** — machine- and run-specific wall-clock floats. + +Every `run create` rewrites the cost column, so the file diffs on every run, on +every machine, and the ordering a fast workstation produces won't match a CI +box. The recent history ("Update costs…", "Update test_costs and a t_end") is +this churn. Split them: keep `num_steps` (and any xfail/skip flags) committed as +test config; push the cost cache into the per-layer DB or a gitignored local +file. + +### 7. Fixed batches leave cores idle; a worker pool would be strictly better + +`executeBatch` launches a window of `jobCount`, then `wait`s for *all* of them +before starting the next window. One slow test in a batch idles every freed core +until the barrier clears. The elaborate cost-sorting is largely a workaround for +this — a dynamic pool (start the next test the moment any slot frees) would beat +fixed batches and make cost-ordering far less load-bearing. + +### 8. A real shell-escaping bug in the Perl fallback + +`scriptPath:gsub("'", "\\'")` (line 377) is incorrect for POSIX single-quoted +strings — inside `'…'` a backslash does not escape the quote; the correct idiom +is `'\''`. Harmless today because paths are developer-controlled and +quote-free, but it is a latent landmine, and the broader pattern of +`'%s'`-quoting everywhere will break on any path containing a quote. + +## Features worth adding + +- **Exit code + machine-readable summary** (JSON/TAP). Unlocks CI gating; highest + leverage. +- **A `diff` subcommand.** The layout deliberately keeps `runs/` beside + `accepted/` "so the developer can diff," but there is no tooling to show + *which fields* diverged and by how much. The data is there; the command isn't. +- **In-test annotations via the existing `--!` magic comment.** That hook already + exists but only does `numProc`-skip. Let tests declare their own `tol`, + `timeout`, `run_to_completion` (never cap steps), and `xfail` — putting "what + is tested and why" *in the test* instead of scattered across `test_costs.lua`, + `ignore_*.lua`, and the 0-step hack (three separate, fragmented skip + mechanisms today). +- **A small set of "full-physics" tests that run uncapped.** Even 5–10 + long-running tests run to completion would restore confidence that the suite + catches late-emerging bugs, while keeping the 5-minute smoke pass for the bulk. +- **Baseline provenance.** Accepted `.gkyl` dirs carry no record of the + commit/build/num_steps that produced them, so you can `check` against stale + baselines and never know. A baseline manifest would catch this. +- **Flake handling.** History shows flaky tests are dealt with by *deletion* + ("remove rt_dg_5m_mom_beach_p2, since it sporadically fails"). A + retry-and-quarantine path would preserve coverage instead of dropping it. +- **MPI coverage.** `mpiExec` is configured but "not yet implemented," and + MPI-marked tests are skipped outright — domain-decomposition correctness, a + classic bug source in a physics code, is entirely uncovered. + +## Bottom line + +The architecture is solid and the engineering details (timeouts, process groups, +abs/rel tolerance, accepted-dir walking) show real care. The concerns cluster +around **integrity**: the step-cap and `num_steps = 0` mechanisms, added under +time pressure to hit a 5-minute target, have shifted the suite from "physics +regression" to "initialization smoke test" — and that shift is invisible in the +output, with 33 crashing tests reporting green. + +Prioritize: + +1. An honest status for the 0-step tests (never `pass`). +2. A real process exit code on failure. +3. Splitting machine-specific costs out of the committed file. + +All three are small changes that restore trust in what a green run actually means. diff --git a/vlasov/apps/vm_fluid_species.c b/vlasov/apps/vm_fluid_species.c index dea50dd085..c238958ef7 100644 --- a/vlasov/apps/vm_fluid_species.c +++ b/vlasov/apps/vm_fluid_species.c @@ -91,8 +91,8 @@ vm_fluid_species_euler_write(gkyl_vlasov_app *app, struct vm_fluid_species *f, snprintf(fileNm_prim, sizeof fileNm_prim, fmt_prim, app->name, f->info.name, frame);
