From 773126e69b2703defb052a5f0a401b070f559ba9 Mon Sep 17 00:00:00 2001 From: Adam Basfop Cavendish Date: Tue, 15 Sep 2026 15:41:07 +0000 Subject: [PATCH] feat: persist workspace state and unify database publication Store service-owned database configuration, effective limits and recovery blockers in TOML under a fixed workspace layout. Restore healthy APIs on startup without registration replay, isolate failed databases, and never recreate missing registered Turso files. Replace public register/migrate/reload with publish and unregister. Validate target changes before adoption, drain requests before migration, apply one migration batch deadline, and atomically publish interfaces with their limits. Preserve configuration through shutdown and retain typed base36 operation IDs only in memory. Cover both backends, restart, configuration persistence faults, target switching and request cleanup. Group PostgreSQL-dependent library tests in postgres_tests modules so the verification script discovers both registry and diagnostic contracts without individual test names. Update HTTP/CLI documentation, runtime guidance and generated SDK examples. Download the pinned openapi-nexus 0.2.3 release binary rather than building it from source. The complete locked check script passes, including PostgreSQL and Turso SDK/restart contracts. --- .github/workflows/ci.yml | 10 +- .gitignore | 4 +- Cargo.lock | 62 + Cargo.toml | 2 + README.md | 17 +- docs/delivery.md | 24 +- docs/getting-started.md | 128 +- docs/http.md | 45 +- docs/interfaces.md | 3 +- docs/migrations.md | 80 +- docs/registry.md | 257 +-- examples/sdk/README.md | 16 +- examples/todolist/README.md | 3 +- scripts/check.sh | 2 + scripts/download-openapi-nexus.sh | 11 + scripts/e2e.py | 75 +- skills/sqlrest-runtime/SKILL.md | 69 +- skills/sqlrest-runtime/references/contract.md | 54 +- src/http.rs | 102 +- src/lib.rs | 1 + src/main.rs | 6 +- src/migration.rs | 10 +- src/postgres_driver.rs | 2 +- src/registry.rs | 1548 +++++++++++------ src/workspace.rs | 534 ++++++ tests/http_contract.rs | 207 +-- tests/migration_contract.rs | 202 ++- tests/registry_contract.rs | 844 ++++----- tests/registry_postgres.rs | 405 ++--- 29 files changed, 2856 insertions(+), 1867 deletions(-) create mode 100644 scripts/download-openapi-nexus.sh create mode 100644 src/workspace.rs diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 34bcbc9..3bfd2a8 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -34,15 +34,13 @@ jobs: run: | rustup toolchain install 1.98.0 --profile minimal --component rustfmt --component clippy sudo apt-get update -
