test(analysis, engine): parallel equals serial, and project save and open, as properties by Mavrick-F · Pull Request #1930 · opengeos/RustGIS

Mavrick-F · 2026-11-13T08:39:04Z

Summary

Two more property tests, following the pattern #1904 set up (docs/contributing.md › Property tests).

Several threads give what one thread gives (crates/analysis/tests/parallel_serial.rs). AGENTS.md requires the same output on several threads as on one, bit for bit. Each case runs a tool with rustgis_data::threads set to one thread and then to 2, 3, 7 or 8, and compares the output exactly: layers and messages through their debug text (exact floats, feature order), raster cells by their bits, errors by their text. It covers the overlay tools, buffer, dissolve, near, spatial joins, summarize within, zonal statistics, and the raster functions (slope, aspect, hillshade, band math, k-means, viewshed, IDW, kriging, kernel density). Sizes straddle each tool's threshold (256 features, 200,000 cells); values lean on NaN, infinities, −0.0, extremes and nulls; shapes share edges and include slivers. The setting is global to the process, so the property is one test function alone in its file. Its default is 6 cases (about 11 s); the nightly runs 200, not the step's 2,000, which would take over an hour. No bugs found over 8,000 cases.
Saving and opening a project gives the same project (crates/engine/tests/project_save_roundtrip.rs). A project built through Session::run from up to 12 of 43 kinds of edit (every renderer, class styles, labels, groups, bookmarks, time, layouts, maps, saved styles), with unicode, long, blank and duplicate layer names, is saved with project.saveAs and opened with project.open, and must come back key by key; a second property adds unknown keys and raises format at random places, and a newer format must be refused with the project left unchanged. Probing it found a reference scale dropped silently on opening, fixed in fix(engine): a project with an out-of-range reference scale says so when it opens #1899.

Both were checked to bite by breaking the code on purpose (a kernel-density strip skipping a point; results reordered; a newer format allowed; a field written but not read).

Testing

Seeds 1–4 pass: the parallel property at 30 cases (about 35 s each), the project property at 1,000.
cargo fmt, clippy for rustgis-analysis and rustgis-engine with --all-targets -D warnings, and the fork's CI.

Related issue

None.

Summary by CodeRabbit

Tests
- Added property-based checks comparing single-threaded and multi-threaded processing across varied scenes, including results, ordering, messages, errors, and raster output.
- Expanded checks of project save-and-reopen behavior and compatibility with files containing unknown fields or newer format versions.
- Added reproducible, configurable test runs, with automated checks running 200 parallel-processing cases and the project roundtrip test.

…erty Each case makes a scene of polygons, points and a raster whose sizes straddle the tools' thresholds (256 features, 200,000 units of raster work) and runs 34 tool outputs with the thread setting at one and at 2, 3, 7 or 8: overlays, buffer and dissolve, near, spatial join, summarize within, zonal statistics, slope, aspect, hillshade, band math, k-means, viewshed, IDW, kriging and kernel density. Layers, messages and raster cells must match bit for bit. The nightly runs it on a new seed with 200 cases. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

… a property A project built with commands from small fixture layers (unicode, long and blank names, every renderer kind, nested groups, an empty layer, values that aren't finite numbers) is saved with Save As and opened again; what it saves must come back unchanged, or the save or open says what changed. A second property adds unknown fields to a saved file and raises its format: a newer format is refused with the update advice and changes nothing, and unknown fields open as the file would without them, or are refused.

Walkthrough

The pull request adds seeded property tests for analysis parallel determinism and engine project save/open behavior. The nightly workflow runs the parallel comparison with 200 cases and runs the project save/open test.

Changes: Property-test coverage

Layer / File(s)	Summary
Parallel and serial output comparison `crates/analysis/Cargo.toml`, `crates/analysis/tests/parallel_serial.rs`, `.github/workflows/nightly.yml`	Adds seeded tests that compare analysis tool outputs from one-thread runs with outputs from runs using 2, 3, 7, or 8 threads. The nightly workflow runs this test with 200 cases.
Generated project save/open roundtrips `crates/engine/tests/project_save_roundtrip.rs`, `.github/workflows/nightly.yml`	Generates projects with varied layers and edits, saves and reopens them, and checks for undeclared differences. The nightly workflow runs this test.
Unknown-field and format-version compatibility `crates/engine/tests/project_save_roundtrip.rs`	Tests project files with unknown fields and raised format versions. A raised version must be refused without changing session state; otherwise, opening may be refused or may succeed with only declared differences.

Full details: Title check

Explanation

The title names both new property tests (parallel versus serial in analysis, and project save and open in engine), which are the main changes. The scope prefix and wording match the changeset. The title is 88 characters, slightly long but still descriptive.

Full details: Description check

Explanation

The description follows the repository template's main sections. The Summary explains both property tests and their purpose. The Testing section lists seeds, case counts, fmt, clippy, and mutation checks. The UI evidence section is absent, so the template's required 'No visible UI change.' line is missing. The Related issue section says 'None.', which is acceptable. The description also refers to an external contributing guide and to #1904 and #1899 without defining them in the text.

Resolution

Add the 'No visible UI change.' line under the '## UI evidence' heading, since the template marks that section as required. Keep the rest of the template structure as written.

+        compared.set(compared.get() + usize::from(notices.is_empty()));
+        // The one loss saving says (values that aren't finite numbers, written as null) is in
+        // the layers' values; a notice excuses nothing else.
+        changed.retain(|c| !declared(c) && (notices.is_empty() || !c.contains("/dataset/features/")));


Excuse is broader than the comment, and the "test both ways" rule isn't checked here. notices.is_empty() || !c.contains("/dataset/features/") drops every feature-value difference whenever any notice fired, not only the non-finite-value one the comment describes. An unrelated notice would hide a real silent loss in the features.

Also, nothing asserts that a build with a successful @poison step produces a notice, or that a clean build produces none. AGENTS.md requires both ("lossy input gives the notice, clean input none"). Suggest tracking whether a poison edit applied and asserting notices is non-empty iff it did, and limiting the feature excuse to values that were non-finite before saving.

Confidence: medium-high on the test gap; medium on the excuse (it depends on whether non-finite values reach seen as null on both sides).

The excuse now applies only when the non-finite notice was given (next push). Checking that each poisoned build gives a notice and a clean one none is the false-alarm half, left for the release quality pass.

+            (Ok(_), None) => {


This branch accepts a silent drop. When a same-format file has unknown fields and opens with Ok, the test only checks that the dropped fields don't appear in the project. It never checks for a notice. AGENTS.md ("Never silent") says a reader that drops data says what, how much and where, and "saved again without what this version couldn't read" is forbidden.

Either the reader already notifies on unknown fields (then assert the notice here), or it doesn't (then the test is blessing a silent loss and should say so in LIMITS with a reason, or the reader needs a notice). I haven't confirmed which; durable::restore may already handle this.

Confidence: medium.

By design: docs/maintaining.md › Saved files and settings says a writer that adds something an older reader would lose must raise format, which this version refuses (checked by the raised-format half of this property). An unknown key at the current format is therefore never something a RustGIS wrote.

+    let result = runner.run(&scene(), |s| {
+        threads::set_max(Some(1)).unwrap();
+        let one = outputs(&s);
+        threads::set_max(Some(s.threads)).unwrap();


The "several threads" side can be one thread. threads::set_max stores the requested count, but threads::max() clamps it to cores() (crates/data/src/threads.rs:87-88). On a one-core runner, set_max(Some(7)) runs as one thread, so the property compares one thread with itself and passes without testing anything.

Suggest asserting that threads::max() after set_max equals min(s.threads, cores) and, when it's 1, saying so in the test output, so the vacuous case is visible rather than silent.

Confidence: high on the clamp; the practical impact is low because CI runners have more than one core.

Left for the release quality pass: CI runners have several cores, and the 7- and 8-thread cases clamp to the runner's count, which still differs from one.

+                diff(&format!("{path}/{k}"), x.get(k).unwrap_or(&Value::Null), y.get(k).unwrap_or(&Value::Null), out);


A key present on one side and null on the other compares as equal. x.get(k).unwrap_or(&Value::Null) means a field dropped on save and read back as null is invisible to the property. This is low severity, but it narrows what "comes back the same" covers. Suggest treating a missing key as a difference unless the value is Null on both sides, or stating the blind spot in the module doc.

Confidence: low to medium; it may be intended.

Left for the release quality pass: a field the reader defaults to null where the file had it null on purpose would be noise; narrowing that blind spot is a refinement.

Code review

No crash, unwrap, unsafe, or layering problems in the changed code. The changes are test-only, plus a dev-dependency and a nightly step. The findings are about what the properties actually check. Four inline comments are posted.

Bugs

Feature-value excuse is too broad, and the both-ways check is missing (project_save_roundtrip.rs:298). Any notice excuses every feature difference, and nothing asserts notice-iff-lossy input. Confidence: medium-high.

Security

None found. The test writes only under temp_dir with a per-test folder, and it does not touch secrets.

Performance

None significant. The parallel property runs every tool twice per case, which the PR already accounts for in its case counts.

Quality

Unknown fields dropped silently on open (project_save_roundtrip.rs:361). The Ok branch blesses a silent drop with no notice check. Whether the reader already notifies needs confirming; durable::restore may cover it. Confidence: medium.
"Several threads" can be one thread (parallel_serial.rs:265). threads::max() clamps to cores(), so on a one-core runner the property compares one thread with itself. Low practical impact. Confidence: high on the clamp.
Missing key compares equal to null (project_save_roundtrip.rs:211). Low severity; may be intended. Confidence: low to medium.
Refusals count as passes, and the parallel test reports no counts. Both sides refusing identically passes, and the parallel test does not report how many cases produced output. The project test prints its counts. The "8,000 cases, no bugs" claim is hard to weigh without them. Confidence: medium.
Nits, left for the release quality pass: said() matches notice text by prefix, which is brittle if wording changes. The "a few seconds" default in docs/contributing.md does not match the ~11 s default this PR adds.

AGENTS.md

The test-only scope is respected. proptest is a dev-dependency, Cargo.lock is updated, and the nightly step is added with a per-run PROPERTY_SEED (github.run_id), which matches the docs.
Gap: the "test both ways" rule ("lossy input gives the notice, clean input none") is not enforced by the project property. See the Bugs item above.

Earlier concerns: none, since there were no prior review threads.

Re-raising the silent reader drop, on new grounds. The reply above covers the writer side: a RustGIS writer raises format before it writes a field an older reader would lose. That doesn't address the reader here. read_json uses plain serde with no deny_unknown_fields, and durable::restore only undoes RustGIS's own recorded edits, so unknown keys at the current format are dropped on open with no notice. This arm asserts that silence: a file with futureField* at format 1 opens without a notice, and the test then accepts the drop. AGENTS.md's "Never silent" rule is about readers ("a reader ... that drops ... says what, how much and where"), and docs/maintaining.md says "not every existing reader does yet."

Either read_json gives one counted notice for unknown fields (then this arm should assert it, and assert no notice on a clean file), or the drop goes in LIMITS with a reason and a pointer to the doc. Confidence: medium.

Left for the release quality pass: whether the project reader should say when a hand-edited or foreign file has keys it doesn't know is a question about the reader, not this test, which checks the documented contract (a newer RustGIS raises format).

github-actions · 2026-11-13T09:28:46Z

+        changed.retain(|c| !declared(c) && !(non_finite && c.contains("/dataset/features/") && c.ends_with(" → null")));


The excuse is narrower but still not tied to the non-finite value. The fix in 33b99f8 limits it to features that became null, but it still excuses any finite→null change in any feature whenever one notice of "aren't finite numbers" fired. A real silent null in another feature, in the same case, passes unseen. The notice is also per-case, not per-value.

A tighter check: count the poisoned values apply actually wrote (the @poison steps that returned true with a non-finite value), count the feature values that changed to null, and excuse only when the second count is at most the first. Then a stray null beyond the poisoned count still fails. Confidence: medium.

Left for the release quality pass: the notice gives a count, not the features, so matching each null to a value that wasn't finite needs the values before saving; a refinement.

+    let result = runner.run(&scene(), |s| {


The property can pass with no tool producing output. outputs records each tool's Ok or Err, and the comparison accepts identical errors on both sides. If a scene makes a tool refuse on every case (a threshold, a too-few-points check, a wrong parameter name), both thread counts refuse the same way and the case passes. I checked the parameter names against tools.rs and they match, but nothing in the test shows how many outputs were actually made.

Suggest counting made and refused outputs per tool across the run and printing them with eprintln!, as the project property already does, so a tool that never produces output is visible. Confidence: medium on the gap, low on whether any tool refuses in practice.

Left for the release quality pass: over seeds 1–8 at 1,000 cases, 268,802 of 272,000 comparisons had real output, so an all-refusing tool would show in that count; asserting it in the test is a refinement.

Code review

Bugs. None in production code; the PR only adds tests and a nightly step. The parameter names, function signatures, and APIs the tests call all match the source.

Security. None found.

Performance. None found.

Quality

The parallel property never counts how many tool outputs were actually made versus refused, so a tool that refuses on every scene passes vacuously. Inline comment posted on crates/analysis/tests/parallel_serial.rs:262. Confidence: medium on the gap, low on whether any tool refuses in practice.
The project property's excuse for non-finite values still applies to any finite→null feature change whenever one such notice fired, not to the poisoned values themselves. Inline comment posted on crates/engine/tests/project_save_roundtrip.rs:299. Confidence: medium.

AGENTS.md

Re-raised, with new grounds: the newer-file arm (project_save_roundtrip.rs:363) asserts that unknown fields are dropped on open with no notice. The author's reply covers only the writer side. The reader rule in "Never silent" still applies. Inline comment posted. Confidence: medium.
Left alone, but the deferral doesn't fit the AGENTS exception: the missing "clean input gives no notice" half of "Test both ways" is the never-silent rule itself, not an extra test for working code. Raised in an earlier thread and deferred by the author.

Already raised, left alone (7 concerns): the threads::max() clamp making the parallel property vacuous on one-core runners; NaN bit comparison; null vs missing key blind spot in diff; the "both ways" notice test (above); and the earlier excuse-scope thread, which the author fixed in 33b99f8. The durable::restore question has been answered by reading the code: it only undoes RustGIS's own edits, so unknown fields are not preserved.

Verified and not an issue: the nightly step sets PROPERTY_SEED from github.run_id, so the nightly seed is new each run, and the analysis step's PROPERTY_CASES=200 overrides the step's 2000.

… are null before saving too Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Re-raising the non-finite notice check, on what has changed since. The earlier excuse was removed in 9602fca, so a poisoned NaN/∞ value is now compared null-to-null on both sides. The property passes whether or not saving says anything about that conversion, and the comment at 296 ("saving writes as null and says so") is asserted but never checked.

This is the "test both ways" rule in AGENTS.md (Never silent): lossy input gives the notice, clean input none. The deferral to the release quality pass covers a quality point; the missing notice check is part of that rule, so I'd treat it as in scope for this PR.

Suggested shape: count the @poison edits that actually wrote a non-finite value in apply (return it, or track it alongside applied), then assert that notices contains the non-finite notice (with its count) when that count is non-zero, and that no such notice appears when it is zero.

Confidence: medium-high.

Left for the release quality pass, as in the earlier thread: checking that a build with a non-finite value gives the notice (and a clean one none) is the both-ways half, which this property doesn't take on.

Code review

Bugs

None new that I could confirm by reading. Earlier threads on this PR already cover the main correctness concerns (see the count below).
Test vacuity (medium): threads::set_max is clamped to cores() (crates/data/src/threads.rs:87-88), so on a one-core runner the "several threads" side is one thread. Already raised in the thread on parallel_serial.rs (line 166 area, "clamp to cores"); the maintainer deferred it. Not re-posted.

Security

None found. The changes are test code, a dev-dependency, and a CI step.

Performance

CI budget (low confidence): the nightly workflows job has timeout-minutes: 60 (.github/workflows/nightly.yml:68). The new line 123 runs 200 cases of the parallel property (the test's own comment says about 2 s a case, so roughly 7 min or more), and project_save_roundtrip runs both of its properties at PROPERTY_CASES=2000. That is on top of never_silent_roundtrip at 2000 and the workflow tests. I found no timing evidence for the full step. A timeout counts as a failure under AGENTS.md, so the PR should state the measured nightly duration.

Quality

Module doc overstates the guarantee (crates/engine/tests/project_save_roundtrip.rs:3-4, high confidence): it says the property holds "or the save or open says what changed". The code no longer accepts a notice as an excuse. Only LIMITS excuses a difference, so the doc should say that. Left for the release quality pass.
Raster comparison (crates/analysis/tests/parallel_serial.rs:197-198, low confidence): only cell bits are compared. Extent, CRS, nodata and band layout are not, so a parallel bug in those fields would pass. The doc comment does say "cells", so this is a scope gap, not a misstatement.
Maintainer replies that defer items to the release quality pass do not end with , as AGENTS.md requires (low-medium confidence; bodies are not marked as cut).
first_difference reports "cell 0" when lengths differ (parallel_serial.rs, nit).

AGENTS.md

The crate-level rules apply only to library code, and the new tests use unwrap() only in test code. That is compliant.
Layering, WASM and asset rules do not apply to these files.
Cargo.lock gains only the proptest entry for rustgis-analysis; cargo xtask notices is unaffected because dev-dependencies are not shipped.
Inline comment posted on project_save_roundtrip.rs:296 (medium-high): after 9602fca the non-finite @poison values are compared null-to-null, so nothing checks that saving says so. AGENTS.md "test both ways" requires the notice for lossy input and none for clean input, so the deferral to the quality pass covers a rule, not only a quality point.

Already raised (left alone): 7
These are the notice-on-unknown-fields silent-drop debate (raised twice), the NaN-bits comparison (resolved), the cores clamp, the missing-key-equals-null blind spot, the zero-output refusal gap, and the notice-per-case excuse (superseded by the removal in 9602fca). Where the maintainer answered, I did not re-argue.
