From 44719412cb1fa17355aef9d5610d0a1fc167624f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Esteban=20Zim=C3=A1nyi?= Date: Mon, 31 Aug 2026 00:13:57 +0200 Subject: [PATCH 1/3] Run the conformance job against a MobilityDB built from master The conformance job builds MobilityDB from master source and runs the Annex A tests that need data against it. Master is what this tier is written against: a job pinned to a release measures a MobilityDB the project no longer develops, so a defect already fixed upstream reads as a live one and blocks work that is not blocked, and deleting a temporal value whose span covers a whole composing sequence segfaults the backend on 1.3.0 and answers correctly on master. Naming a version somebody can install is a reason to also run a release, never a reason to develop against one. A published image is not the source either. The mobilitydb/mobilitydb tags are built by MobilityDB/MobilityDB-docker, a separate repository on its own schedule, so what a tag carries is that repository's packaging rather than the source under test: 18-3.6-master fails to load the library on a missing libgdal.so.39, and 17-3.5-master exits its own entrypoint because the pointcloud extension it asks for is not available. The build recipe is MobilityDB's own .github/workflows/pgversion.yml, and its apt hardening is taken from the checkout rather than copied, so the job follows the project's build as it changes. The families stay at their defaults, which is the surface the routes reach, and loading the extension is a step of its own so that a database which cannot carry MobilityDB says so before the fixture runs. --- .github/workflows/go.yml | 105 ++++++++++++++++++++++++++++++++------- 1 file changed, 87 insertions(+), 18 deletions(-) diff --git a/.github/workflows/go.yml b/.github/workflows/go.yml index e340997..b936743 100644 --- a/.github/workflows/go.yml +++ b/.github/workflows/go.yml @@ -43,35 +43,104 @@ jobs: # The Annex A tests that read or write data, against a database.

Each lifecycle creates its own subject and removes it, so the fixture the read-side tests assert against is untouched, and each parameter assertion is that the answer MOVES: a parameter read and not acted on cannot be told from one ignored. `atsDischargedBy` names, per abstract test needing a backend, the live test that discharges it, and the registry reports that name rather than an unconditional "awaits its live assertion" — which reports a row a named group already asserts as outstanding, so the tier's own coverage report understates its conformance. The map is built from what a test CALLS: the temporal-property lifecycle posts to the plural route, so it discharges tproperties-post-success and not the singular tproperty-post-success. `TestATSEveryLiveRowIsDischarged` keeps every row carrying an entry that names a test the suite declares. --- ats_live_test.go | 164 ++++++++++++++++++++++++++++++++++++++++++++++ ats_part1_test.go | 76 ++++++++++++++++++++- 2 files changed, 239 insertions(+), 1 deletion(-) diff --git a/ats_live_test.go b/ats_live_test.go index e1ab1e3..02c2b83 100644 --- a/ats_live_test.go +++ b/ats_live_test.go @@ -19,6 +19,7 @@ import ( "net/http" "net/http/httptest" "os" + "strconv" "strings" "testing" ) @@ -259,3 +260,166 @@ func TestATSLiveSubTemporalValue(t *testing.T) { rec.Code, rec.Body.String()) } } + +// /conf/movingfeatures/features-post-success, mf-delete-success, +// tgsequence-post-success and tpgeometry-delete-success: the moving-feature +// lifecycle, on a feature this test creates so the fixture is untouched. +func TestATSLiveFeatureLifecycle(t *testing.T) { + mux, done := atsLiveMux(t) + defer done() + const items = "/collections/conformance/items" + + // A trajectory disjoint in time from the fixture's, so a merge into it cannot + // collide and the 409 the tier answers on overlap is not what is measured here. + const tg = `{"type":"MovingPoint","coordinates":[[575000,6220000],[576000,6220500]],` + + `"datetimes":["2026-03-01T08:00:00Z","2026-03-01T08:10:00Z"],"interpolation":"Linear"}` + rec := atsDo(t, mux, "POST", items, + `{"properties":{"mmsi":999999,"name":"ats_feature"},"temporalGeometry":`+tg+`}`) + if !oneOf(rec.Code, 201, 202) { + t.Fatalf("POST %s = %d, want 201 or 202 (%s)", items, rec.Code, rec.Body.String()) + } + fid := atsCreatedID(t, rec) + defer atsDo(t, mux, "DELETE", items+"/"+fid, "") + + if rec := atsDo(t, mux, "GET", items+"/"+fid, ""); rec.Code != 200 { + t.Fatalf("the created feature reads %d, want 200 (%s)", rec.Code, rec.Body.String()) + } + + // A second sequence, later again, so the feature carries two and the delete + // below has one to remove while leaving the feature readable. + const tg2 = `{"type":"MovingPoint","coordinates":[[577000,6221000],[578000,6221500]],` + + `"datetimes":["2026-03-01T09:00:00Z","2026-03-01T09:10:00Z"],"interpolation":"Linear"}` + rec = atsDo(t, mux, "POST", items+"/"+fid+"/tgsequence", tg2) + if !oneOf(rec.Code, 201, 202) { + t.Fatalf("POST tgsequence = %d, want 201 or 202 (%s)", rec.Code, rec.Body.String()) + } + + rec = atsDo(t, mux, "DELETE", items+"/"+fid+"/tgsequence/2", "") + if !oneOf(rec.Code, 200, 202, 204) { + t.Errorf("DELETE tgsequence/2 = %d, want 200, 202 or 204 (%s)", rec.Code, rec.Body.String()) + } + + rec = atsDo(t, mux, "DELETE", items+"/"+fid, "") + if !oneOf(rec.Code, 200, 202, 204) { + t.Errorf("DELETE %s/%s = %d, want 200, 202 or 204 (%s)", items, fid, rec.Code, rec.Body.String()) + } + if rec := atsDo(t, mux, "GET", items+"/"+fid, ""); rec.Code != 404 { + t.Errorf("the deleted feature answers %d, want 404", rec.Code) + } +} + +// atsCreatedID reads the identifier a creation answers with, so a lifecycle +// removes what it made rather than guessing at an id the fixture may reuse. +func atsCreatedID(t *testing.T, rec *httptest.ResponseRecorder) string { + t.Helper() + var doc map[string]any + if err := json.Unmarshal(rec.Body.Bytes(), &doc); err != nil { + t.Fatalf("the creation response is not JSON: %v (%s)", err, rec.Body.String()) + } + for _, k := range []string{"id", "fid", "featureId"} { + switch v := doc[k].(type) { + case string: + return v + case float64: + return strconv.FormatFloat(v, 'f', -1, 64) + } + } + t.Fatalf("the creation response names no identifier: %s", rec.Body.String()) + return "" +} + +// /conf/movingfeatures/tproperty-post-success and tpvalue-delete-success: values +// appended to a property this test creates, and one of them removed. +func TestATSLiveTemporalPropertyValues(t *testing.T) { + mux, done := atsLiveMux(t) + defer done() + const base = "/collections/conformance/items/1/tproperties" + const name = "ats_values" + defer atsDo(t, mux, "DELETE", base+"/"+name, "") + + rec := atsDo(t, mux, "POST", base, + `[{"name":"`+name+`","type":"TReal","form":"http://www.opengis.net/def/uom/UCUM/0/m",`+ + `"description":"added by the conformance suite",`+ + `"datetimes":["2026-01-01T08:00:00+00","2026-01-01T08:10:00+00"],`+ + `"values":[1.0,2.0],"interpolation":"Linear"}]`) + if !oneOf(rec.Code, 200, 201, 202) { + t.Fatalf("POST %s = %d, want 201 or 202 (%s)", base, rec.Code, rec.Body.String()) + } + + // Appending to the property itself, which is the singular route the plural one + // above does not exercise.
