From 8dffc770e905b1c89827cda8ab3264991720be09 Mon Sep 17 00:00:00 2001 From: rasmusjen Date: Wed, 19 Aug 2026 07:07:29 +0200 Subject: [PATCH 1/9] chore: clean up refactor residue and tooling inconsistencies Housekeeping found during a structural audit, all left over from the migration away from the monolithic eddypro_batch_processor.py script. - Remove tests/.coverage, a binary coverage artifact that was tracked in git despite .gitignore listing .coverage. Add **/ patterns so nested coverage and mypy caches are ignored too. - Drop src/__init__.py. It made `src` itself an importable package, which is wrong under a src-layout with hatchling, and its docstring still described the package as "refactoring from monolithic script". - Remove the mypy and bandit `src/eddypro_batch_processor\.py` exclusions from pre-commit; that path is the old monolith and no longer exists, so the exclusions were dead. - Stop running both `ruff format --check` and `black --check` in CI. The two formatters can disagree and the build had no tiebreaker; black is what pre-commit enforces, so keep black and use ruff for linting only. - Derive __version__ from importlib.metadata. pyproject declared 0.3.0 while __init__.py hardcoded 0.1.0; deriving it makes the skew impossible to reintroduce. - Rewrite requirements.txt to match pyproject. It pinned requests, urllib3, certifi, idna and charset-normalizer (none of which are imported anywhere) while omitting tqdm and pandas, which are real dependencies. - Drop shebangs from ecmd.py and scenarios.py; these modules are imported, never executed directly.

Only the scenarios.py version is used in production. The ini_tools copy was dead outside its own tests, but because both were tested the suite actively enshrined two incompatible suffix formats, so a future caller picking the wrong import would have silently produced mismatched output directory names. Delete the ini_tools copy and its tests; scenarios.generate_scenario_suffix remains the single implementation.

From ead27b90fe35c5df8eb96f309485a7be32792dda Mon Sep 17 00:00:00 2001 From: rasmusjen Date: Wed, 19 Aug 2026 07:08:54 +0200 Subject: [PATCH 3/9] fix(monitor): sample the real process tree and emit usable metrics The monitor reported 0.0 for CPU and disk I/O on every run. Verified against a real 2.7-hour GL-ZaF run (18,818 samples): process_cpu_percent min/max/mean all 0.0, process_io_read_bytes and write_bytes all 0.0, and process_memory_rss averaging 4.9 MB. Root cause: the monitor was pointed at a single PID, which (see the following commit for the launch-side fix) was the cmd.exe wrapper rather than EddyPro. 4.9 MB RSS is cmd.exe's footprint exactly. Changes: - Sample a process TREE. Every sample re-walks root.children(recursive=True) and aggregates CPU, RSS and I/O across it, so EddyPro workers spawned mid-run are picked up. - Add attach_process(), so a caller can start the monitor and then point it at a subprocess. This replaces the stop_monitoring()/start_monitoring(pid) dance, which wrote a one-sample CSV and summary JSON before overwriting them at the real stop. - Prime cpu_percent() both system-wide and per process. The first call after construction always returns 0.0 because there is no previous measurement to diff against, so the first sample was guaranteed meaningless. - Derive disk RATES. psutil's counters are monotonic since boot, so the old output reported since-boot totals and then took min/max/mean/p95 over them, which is not a meaningful statistic. Now emits read_mb/write_mb (cumulative since monitoring started) plus read_mb_per_s, write_mb_per_s, read_iops and write_iops derived from deltas over the ACTUAL elapsed time between samples, not the nominal interval, which drifts. - Never disable monitoring on a transient error. A single AccessDenied used to null self._process permanently, silently dropping all process columns for the remainder of the run. Errors are now handled per process. - Emit a fixed canonical column set (METRICS_FIELDNAMES) whose first columns are exactly what report.py reads, so the CSV is never ragged. - Report CPU two ways: cpu_percent normalised by core count (comparable with system_cpu_percent, and the right basis for "is the machine saturated"), and cpu_percent_of_core un-normalised, where 100 means one core fully busy. EddyPro is largely single-threaded, so the latter is what reveals a pegged core on a many-core machine. - Guard _samples with a lock (sampler thread vs CSV writer) and raise the join timeout above one sampling period. - Fix the "Duration: 0.00s" log line, which read summary["duration_seconds"] when the value lives under summary["timing"]. - Hold cumulative totals after the tree exits rather than resetting them to zero, so read_mb/write_mb stay monotonic as consumers chart them. Verified on a real subprocess: 96.3% of one core, real RSS, 716 MB read and ~200 MB/s sustained, where every one of those figures was previously 0.0.

From bfedc05f1328bd4997df78b496604436d43bd7af Mon Sep 17 00:00:00 2001 From: rasmusjen Date: Wed, 19 Aug 2026 07:09:31 +0200 Subject: [PATCH 4/9] feat(analysis): add bottleneck classification and fix the run manifest Adds the analysis layer described in docs/plan/PERFORMANCE_ANALYSIS_DESIGN.md and repairs the manifest defects found alongside it. New src/eddypro_batch_processor/analysis.py: - BottleneckAnalyzer digests a metrics CSV into mean/max/p95 per resource and classifies the run as CPU, MEMORY, DISK_THROUGHPUT, DISK_IOPS or NONE, with a RED/YELLOW/GREEN status per resource and a plain-language explanation. - Sustained load (p95) drives the verdict rather than peaks. A saturated CPU outranks a busy disk; a busy disk paired with an idle CPU means the run was waiting on storage. - Thresholds are tunable via a performance_thresholds config block. Defaults assume a mechanical disk and should be raised for NVMe. - Stdlib only, no pandas, so the reporting path stays import-light. report.py, charts: - load_metrics_from_csv read cpu_percent/memory_mb/read_mb/write_mb while the monitor wrote system_cpu_percent/process_memory_rss in bytes. Every lookup missed and defaulted to 0, so the HTML charts were flat zero lines regardless of what had been sampled. This was known issue #3. Coercion is now per field so one blank cell cannot abandon the rest of the row. - Add a Performance Health Check table (traffic lights + primary bottleneck) and a Per-Year Results table to the HTML report. report.py, manifest: - config_checksum used str(hash(json.dumps(...))). Python's hash() is salted per process by PYTHONHASHSEED, so the SAME config produced a DIFFERENT checksum on every run, making the field useless for comparing runs. Now a real SHA256 over the canonicalised config. A correct sha256 helper already existed in this module but was never called outside tests. - Write the manifest atomically (tmp file + os.replace). It was written straight to the destination, so a crash mid-write left truncated JSON that had already destroyed the previous good manifest. cmd_status already caught JSONDecodeError, i.e. the code anticipated corruption instead of preventing it. - Archive a per-run copy under manifests/run_manifest_{run_id}.json, since the canonical filename is fixed and consecutive runs overwrote each other's provenance. - Add manifest_schema_version, a status field, a years[] array carrying per-year outcome including failures, and an errors[] list. - Add get_provenance()/get_git_provenance() recording git SHA, dirty flag, branch, tool version, argv and the EddyPro executable path plus checksum. README and REPORTING.md have long claimed git SHA and EddyPro version were captured; the provenance parameter existed but no caller ever passed it, so the key never appeared in any manifest.

Launch path (the root cause of the all-zero metrics): - run_subprocess_with_monitoring now takes an argv list and runs WITHOUT shell=True. Under a shell on Windows, Popen spawns `cmd.exe /c ...`, so Popen.pid is the wrapper's PID and EddyPro is only its child. That PID was handed to the monitor, which therefore sampled an idle shell for the entire run. Everything downstream of this was measuring cmd.exe. - Use monitor.attach_process() instead of stop/restart, so the metrics files are written once at the end rather than truncated at the start. Monitoring toggle (implements docs/plan/MONITORING_TOGGLE_IMPLEMENTATION_PLAN): - New monitoring_enabled config key, default true, threaded through run_eddypro_with_monitoring, run_single_scenario and run_scenario_batch. When false no monitor is created and no metrics files are written. - New --monitor/--no-monitor flags on both run and scenarios. - validation.py type-checks the key and only requires a positive metrics_interval_seconds when monitoring is actually enabled. - Fix an override bug while here: --metrics-interval defaulted to 0.5, which is truthy, so `if args.metrics_interval:` always fired and metrics_interval_seconds from config.yaml was silently overwritten on every run. The default is now None and scenarios honours config too. Multiprocessing (previously validated and advertised but never applied): - Extract the per-year body into module-level process_year(), which takes a plain dict so it is picklable, and dispatch years over a ProcessPoolExecutor when multiprocessing is enabled. Worker count is capped by max_processes, the number of years, and os.cpu_count(). - Results are reordered deterministically; completion order is not stable. - process_year never raises: failures become records, so one bad year cannot abort the run and, crucially, stays visible in the manifest. - Output streaming is suppressed while running in parallel, since interleaved stdout from several EddyPro processes is unreadable. Output still reaches the log file. - Workers re-establish logging, which a fresh process does not inherit. Manifest and reporting: - Report generation no longer sits behind `if years_processed:`. A run in which every year failed is exactly the run whose manifest matters most, and previously produced no manifest at all. - Per-year records, run-level errors, provenance and the bottleneck summary are passed into the manifest; timestamps are UTC with an offset instead of naive local time. - scenarios now generates the per-scenario and aggregate HTML reports that docs/SCENARIOS.md promised, and emits scenario_name (prefixed with the year, so entries stay unambiguous across years) from both the run and scenarios paths. cmd_status read scenario_name while scenarios wrote only scenario_index/scenario_suffix, so every scenario showed as "unknown". - A failing scenario now leaves a manifest behind. The error metadata was built in the exception handler and then discarded, because the only json.dump was on the success path. - cmd_status read manifest["outputs"] when the key is "output_dirs", so the Output Directories section never rendered. It now also prints the per-year table and the bottleneck verdict. - Add a global --version flag, which README already told users to run, and --reports-dir on scenarios, which docs/SCENARIOS.md already documented. tests/test_analysis.py adds an intentionally un-mocked test that runs a real workload under the real monitor. Every existing monitor test mocks psutil wholesale, which is why this class of bug survived in CI; that test asserts CPU and disk figures are non-zero and would fail if the shell=True regression returned.

Covers the .venv (a stale second venv/ also exists, which is a live footgun), the test and lint commands, the module map, and the domain rules that matter most here: EddyPro runs take hours so never launch one speculatively, and never write to data/, logs/, D:/L0_raw/ or D:/L1_processed/, which hold irreplaceable field data. Defers to copilot-instructions.md for code-quality rules rather than duplicating them. - Skills: git-commit (deliberate staging, Conventional Commits matching this repo's history, never --no-verify, never stage config/config.yaml or data), git-branch-pr (branch naming, never commit to main, rebase vs merge, gh pr create with the repo template, CI green before merge, --force-with-lease only), and release (bump pyproject only, since __version__ is now derived). - Hooks, wired in .claude/settings.json: - pretooluse_guard.py blocks force-push, any push to main, commits on main, --no-verify, reset --hard, clean -fdx, filter-branch, staging protected paths, and Edit/Write under the protected data directories. Chained commands are split and checked segment by segment, and matching is on git subcommand boundaries so `echo "my data is fine"` is not a false positive. - posttooluse_format.py runs black and ruff --fix on just the edited file and reports anything left over as advisory feedback. Verified with 15 payload cases covering each blocked operation, the allowed counterparts, and the false-positive case.

New docs/MULTI_YEAR_RUNS.md, the headline addition. Opens by distinguishing the two concepts, because they were conflated throughout: a multi-year run applies the SAME settings across several years, while a scenario run applies several combinations of EddyPro processing parameters to the same years. Then a fully worked GL-Dsk 2020-2025 example given both as a config file (new examples/multi_year_config.yaml) and as pure CLI, plus dry-run guidance, the --no-monitor variant, what lands where, how to read the bottleneck table, and the caveats (years are independent, a failed year is skipped and the run continues, reports_dir defaults to the first year's output directory). Corrections, each verified against the source: - README and REPORTING.md claimed provenance capture of git SHA and EddyPro version. Nothing invoked git and the provenance parameter was never passed. Now accurate for what is actually recorded; no input-checksum claims. - REPORTING.md described config_checksum as "SHA256 of config file content". It was str(hash(...)). Now describes what is really computed. - USAGE.md showed sample output with checkmark and cross glyphs; the code emits ASCII [PASS]/[FAIL]/-. - CONFIG.md said years run in parallel with multiprocessing, then contradicted itself 100 lines later by admitting it was not implemented. Multiprocessing is now real, so the contradiction is removed. - CONFIG.md and ARCHITECTURE.md claimed plotly falls back to SVG with a warning; the code only logs at debug and renders without charts. - README linked docs/plan/IMPROVEMENT_PLAN.md, which lives under plan/implemented/. - KNOWN_ISSUES_AND_TODO.md rewritten: issues 3-6 are fixed by this branch; issues 1, 2 and 7 remain and are stated accurately. De-duplication: the full config example appeared five times with divergent values. config/config.yaml.example is now the single source of truth and the others show a short excerpt and link to it. Scenario CLI examples are owned by docs/SCENARIOS.md. Also documents the new monitoring_enabled and performance_thresholds keys, the --monitor/--no-monitor, --version and scenarios --reports-dir flags, and moves the two now-implemented plans into docs/plan/implemented/. All relative links checked and resolving; all documented CLI invocations verified to parse; all example configs verified to validate.

The two had drifted years apart: CI was resolving ruff 0.16.3 and black 26.5.1, so the hooks passed locally and the same code failed in CI. Two concrete breakages, both of which also affect main: - ruff promoted PLR0917 (too many positional arguments) out of preview. It fires 7 times, on functions that already existed before this branch. Added to the ignore list next to PLR0913, which is ignored for exactly the same reason: these are configuration-heavy functions in scientific code, and they are keyword-called at every call site. - black's 26.x stable style changed how it wraps parenthesized assignments and multiline string arguments. black 23 and black 26 reformat the same code in opposite directions, so with the old pins the two would have fought forever. Fixes: - Bound ruff and black in the dev extra so CI cannot silently pick up a formatter release that disagrees with the hooks. - Bump the pre-commit revs to the same versions CI now installs, so local and CI agree by construction, and switch to the non-deprecated `ruff-check` hook id. - Reformat under black 26.5.1. mypy is deliberately left at 1.8.0 in pre-commit: the CI mypy step is `continue-on-error`, so it cannot break the build, and bumping to 2.x is a larger change than belongs in this branch. Verified by installing ruff 0.16.3 and black 26.5.1 locally and running both checks, rather than by pushing and waiting for CI.

That holds on Windows but not on Linux, where io_counters().read_bytes counts only bytes actually fetched from the storage layer: the burner reads back a file it just wrote, which is served from the page cache, so zero reads is the correct reading rather than a monitoring failure. Assert on combined read+write instead, for both the cumulative totals and the derived rates. Writes are fsync'd, so the combined figure is non-zero on every platform. The CPU and memory assertions are unchanged and already passed on the Linux runners; those are the ones that actually guard against the monitor being pointed at a shell wrapper instead of the real workload.
