Reversal would either flatten the pipeline (breaking testability) or expose the pipeline (breaking the simple public contract). + +## Rejected Approaches + +- **Approach A — Couchbase-Clone (runtime middleware only):** Lost on requirements compliance (~85%). Pure runtime middleware sees fully-built JSON and cannot satisfy R-08a/R-17/R-18's parse-time error contracts. Component-template detection (`composed_of` presence in AST vs JSON tree walk) is harder at runtime; UNSAFE token validation must happen at parse anyway. State machine alone (no pipeline) is verbose and harder to test in isolation than the façade-over-pipeline shape C adopts. +- **Approach B — Parser-First Composition (parser only, provision-on-demand, IBootstrapStep pipeline):** Lost on requirements compliance (~82%) and lock-init race. Pure parser cannot route logs through SecretScrubber (R-25); cannot emit structured WARN events from response paths; cannot observe Tasks API progress. Provision-on-demand for lock index introduces a race window during the very first concurrent acquire (the laziest CI matrix run becomes the worst case for race exposure). Pipeline-only public API loses the simple Couchbase-shaped contract that house-style consistency demands. + +## Risks and Open Questions + +### Riskiest assumption (validate early) + +**The runtime middleware can correctly merge AST safe-default flags into arbitrary user-supplied JSON bodies.** Specifically: `op_type: create` injection on `_reindex` request bodies that already contain a `dest` object; `dynamic: strict` injection into `mappings.properties` when only `mappings` is present at the top level; preservation of an existing `dynamic: true` set explicitly by the author. This must be the first integration test written — it validates the parser/runtime split before any other component is built. If the merge logic is fragile, the architecture's primary advantage collapses. + +### Other open questions worth surfacing + +- **Pipeline parallelism within bootstrapper:** the `IBootstrapStep[]` pipeline could run independent steps (ledger + lock init) in parallel. Worth doing? If yes, step dependencies must be declared (`DependsOn` attribute or topological sort). If no, the linear sequential model is simpler. Recommend **linear in v1** unless a concrete bottleneck emerges in R-24c's measured-cost test. +- **Middleware ordering:** if a consumer adds a custom `IStatementMiddleware`, the position in the chain matters. Need a documented order convention (`Order` attribute) and a test that asserts the built-in middleware order. +- **`AssumeIndicesExist = true` validation:** when set, `InitializeAsync` skips create but does it *verify* the indices exist with the expected mapping? Recommend yes — verification is cheap; silent acceptance of missing indices is worse than the cost. +- **Hyperbee.Templating + SecretMarker integration:** marker preservation across template engine output is the riskiest first-contact bug (PM-5). Validate against a representative `{{#if}}` and `{{each}}` JSON template before writing other code. +- **State-machine façade observability:** the public `BootstrapResult` should expose per-step status for log aggregation. Recommend enumerating the steps in `BootstrapResult.Steps` so operators can see exactly which step failed without parsing log strings. + +## Recommended next steps + +1. **Run `/nop:adr` four times** to materialize ADRs 0011-0014 (or run `/nop:adr derive` to mine them from this spec in one pass) +2. **Run `/nop:plan`** to decompose into phased tasks. Suggest first phase = riskiest-assumption validation: parser AST + runtime middleware merge logic + tests against representative bodies (the validation listed above) +3. **Optional:** `/nop:assess` on this design before planning — the design is mid-stakes (production-capable provider but with mature precedent in Couchbase). Stakes don't justify a second Full Assessment, but a `/nop:red-blue` pass on the design could catch design-level gold-plating before plan-time diff --git a/docs/plans/active/INDEX.md b/docs/plans/active/INDEX.md new file mode 100644 index 0000000..19f49d4 --- /dev/null +++ b/docs/plans/active/INDEX.md @@ -0,0 +1,5 @@ +# plans/active/INDEX.md + +| Plan | Title | Status | Created | Summary | +|---------------------|----------------------------------------------------------------|--------|------------|------------------------------------------------------------------------------------------| +| opensearch-provider | [OpenSearch Provider for Hyperbee.Migrations](opensearch-provider.md) | Active | 2026-05-02 | 4 phases collapsed from initial 8 after velocity recalibration (3-7 days focused work).

Influences: verb set in R-08a. +- **Security-plugin objects (roles, role mappings) as v1 verbs** — Status: deferred. Reason: requires admin-cert auth which complicates DI; tenant model is a separate design problem. Leaning: not in v1. Depends on: scope decision. Influences: verb set in R-08a, Out of Scope. +- **Semantic unsafe-operation detection (R-18 deep tier)** — Status: deferred. Reason: requires reading live mapping/index state at parse or pre-execute time; semantic understanding of query effects is a research project. Leaning: ship syntactic enumeration in v1; semantic detection in v1.1 if real-world incidents justify. Depends on: post-v1 incident telemetry. Influences: R-18. +- **`WHEN VERSION` long-tail suffix support** — Status: deferred. Reason: AWS `OpenSearch_<x>` prefix and `-rc<N>` / `-SNAPSHOT` qualifiers will need normalization rules as they appear in real clusters. Leaning: ship clean `MAJOR.MINOR.PATCH` + documented suffix rules in v1; tighten as needed. Depends on: production diversity. Influences: R-15a. +- **AWS Managed OpenSearch CI automation** — Status: deferred (Should). Reason: requires AWS account scaffolding and credentials in CI. Leaning: scheduled validation runbook in v1; full automation v1.1+. Depends on: project AWS account access. Influences: R-28. +- **JSON Schema for `statements.json` (IDE help)** — Status: deferred. Reason: nice-to-have IDE ergonomics; not blocking correctness. Leaning: v1.1. Depends on: adopter feedback. Influences: R-08, R-09. +- **Topology-aware bulk-load parallelism** — Status: deferred. Reason: PA-6 says default 8x parallelism saturates small-node thread pools and triggers self-induced 429s. Leaning: ship with conservative defaults documented; add adaptive tuning in v1.1. Depends on: real-cluster benchmarks. Influences: R-20. +- **OpenSearch.Client v2 / cluster 3.x compatibility** — Status: monitor. Reason: PM-8 says client may go stagnant against 3.x clusters. Leaning: track upgrade cadence; canary against `next-major` Testcontainers image; bump pinned image when 3.x ships. Depends on: OpenSearch project release schedule. Influences: R-24a, Constraints. + +## Recommended next steps + +1. **`/nop:propose`** to evaluate concrete implementation strategies against these requirements as fitness criteria. The remaining tensions (Open Questions) are mostly scope decisions; the load-bearing implementation choices to evaluate are: (a) parser-level injection vs runtime middleware for `op_type: create` and `dynamic: strict`; (b) lock-index initialization (provision-on-demand vs explicit options); (c) `WithProductionDefaults()` implementation (extension method vs builder pattern); (d) bootstrapper architecture (state machine like Couchbase vs simpler async sequence). +2. **`/nop:plan`** once propose selects a winner. diff --git a/docs/research/0001-opensearch-provider.md b/docs/research/0001-opensearch-provider.md new file mode 100644 index 0000000..a8b1604 --- /dev/null +++ b/docs/research/0001-opensearch-provider.md @@ -0,0 +1,400 @@ +# Research: OpenSearch Provider for Hyperbee.Migrations + +**Date:** 2026-05-02 +**Status:** Draft +**Author:** Brenton Farmer (with research agents) +**Related:** Future ADRs for OpenSearch provider design + +## Purpose + +Scope a new OpenSearch provider for Hyperbee.Migrations.

It does not commit to an implementation; that is the role of the follow-on `nop:propose` evaluating concrete grammar/architecture options. + +--- + +## 1. Existing Provider Patterns (In-House Prior Art) + +### 1.1 Core contract + +[MigrationRunner](../../src/Hyperbee.Migrations/MigrationRunner.cs) orchestrates: `InitializeAsync` → `CreateLockAsync` (returns IDisposable) → reflection discovery → sequential `UpAsync`/`DownAsync` → journal `WriteAsync`/`DeleteAsync`. + +[IMigrationRecordStore](../../src/Hyperbee.Migrations/IMigrationRecordStore.cs) defines seven methods total. [MigrationRecord](../../src/Hyperbee.Migrations/MigrationRecord.cs) is minimal: `{ Id, RunOn }`. The runner is stateless; the store holds all state. + +All providers implement `IMigrationRecordStore` directly and inherit from `MigrationOptions`. ADR-0003 formalizes this contract; ADR-0006 formalizes the options hierarchy. + +### 1.2 Resource migrations + +The convention across NoSQL providers (ADR-0002): + +```json +{ "statements": [ { "statement": "..." } ] } +``` + +| Provider | Statement language | Document loader | Grammar | +|-----------|-----------------------------|-----------------------|---------| +| Aerospike | Subset of AQL | `DocumentsFromAsync` | Parlot | +| Couchbase | Partial N1QL | `DocumentsFromAsync` | Parlot | +| MongoDB | Mongo shell-like commands | `DocumentsFromAsync` | Parlot | +| Postgres | Raw SQL files (no parsing) | None (procedural) | None | + +Resource discovery is via embedded assembly resources, addressed by `Migration.VersionedName<T>()` (ADR-0009). + +### 1.3 Templating + +**No provider currently uses templating.** Hyperbee.Templating exists in-house with `{{name}}`, `{{x => x.Foo()}}`, `{{#if}}`/`{{/if}}`, `{{each}}`/`{{while}}`, and `{{name:value}}` syntax — but no migration provider has wired it in. Substitution is currently done from typed options at runtime (e.g., `_options.Namespace` in Aerospike). OpenSearch will be the first provider to require true file-level templating because mappings, replica counts, analyzer chains, and ISM policy values vary across environments. + +### 1.4 Statement grammar + +Three providers use Parlot (ADR-0001) for partial DSLs. Each grammar: + +- **Aerospike**: `CREATE INDEX [IF NOT EXISTS] [RECREATE] [WAIT] name ON ns.set (bin) [STRING|NUMERIC|GEO2DSPHERE]`, `DROP INDEX ns indexname`, `CREATE SET`, `INSERT INTO`, `DELETE FROM` +- **Couchbase**: `CREATE BUCKET ... TYPE ... RAMQUOTA ... FLUSH ENABLED ... REPLICAS`, `CREATE [PRIMARY] INDEX`, `CREATE SCOPE`, `CREATE COLLECTION`, `BUILD INDEX ON`, `UPDATE ... SET`, `DROP {BUCKET|SCOPE|COLLECTION}` +- **MongoDB**: `CREATE COLLECTION`, `DROP COLLECTION`, `CREATE [UNIQUE] INDEX name ON db.collection(field, ...)`, `DROP INDEX name ON db.collection` + +All grammars are deliberately partial — they recognize verb prefixes; everything past that point is passed through to the database client. This is the key idea worth replicating for OpenSearch: thin shell over opaque payloads. + +### 1.5 Async/sync model + +All record store methods are `async Task`. Cancellation tokens thread through runner → store → resource runners. Timeouts use a custom [TimeoutTokenSource](../../src/Hyperbee.Migrations/Wait/TimeoutTokenSource.cs) + linked CTS pattern. + +### 1.6 Warmup / readiness + +Spectrum across the four providers: + +| Provider | Warmup style | +|-----------|------------------------------------------------------------------------------------------------------------| +| Postgres | None; `InitializeAsync` creates schema + table inline | +| MongoDB | None; just acquires the database handle | +| Aerospike | Per-operation: `WaitForIndexReadyAsync` polls `sindex/<ns>/<idx>` info command, 500ms→5s exponential, 60s default | +| Couchbase | 7-state bootstrapper: REST ping → cluster healthy → 5s settle → `WaitUntilReadyAsync` → bucket ready → sacrificial query | + +Couchbase is the most complex by a wide margin and is the closest behavioral analog for OpenSearch (multi-node cluster, eventual consistency on metadata, "ready vs healthy" distinction). [WaitHelper.WaitUntilAsync](../../src/Hyperbee.Migrations/Wait/WaitHelper.cs) + [PauseRetryStrategy](../../src/Hyperbee.Migrations/Wait/RetryStrategy.cs) (ADR-0008) are the reusable primitives. + +### 1.7 Distributed locking + +| Provider | Lock pattern | +|-----------|-----------------------------------------------------------------------------------------------| +| Aerospike | CAS `Put` with `RecordExistsAction.CREATE_ONLY` + TTL + background `Touch` renewal loop using `TimeProvider` | +| Couchbase | `RequestMutexAsync` + `AutoRenew()` from `Couchbase.Extensions.Locks` | +| MongoDB | Document with `LockedOn`/`ReleaseOn` timestamps; manual expiry check; no renewal | +| Postgres | Dedicated `ledger_lock` row with `release_on`; manual expiry check; no renewal | + +The Aerospike auto-renewing lock (recently shipped) is the freshest and most robust pattern. ADR-0005 documents the provider-native locking decision. The Aerospike pattern translates directly to OpenSearch via `_seq_no`/`_primary_term` CAS — there is no native lock primitive in OpenSearch, and no .NET library provides one. + +### 1.8 Migration record stores + +| Provider | Storage | Lock storage | +|-----------|--------------------------------------|-----------------------------------------| +| Aerospike | Set `SchemaMigrations`, key=record id, bins `Name`/`ExecutedAt` | Same set, key `migration_lock` | +| Couchbase | Bucket `ledger`, scope `migrations`, collection `ledger` | Same collection, doc id = lock name | +| MongoDB | Database `migration`, collection `ledger` | Same collection, fixed id `1` | +| Postgres | Schema `migration`, table `ledger` | Separate table `ledger_lock` | + +### 1.9 DI shape + +```csharp +services.AddXxxMigrations( options => { + options.Assemblies.Add( typeof(MyMigration).Assembly ); + options.LockingEnabled = true; +} ); +``` + +Options factory binds `IConfiguration` (`Migrations:FromAssemblies`, `Migrations:FromPaths`) merged with the lambda. `IMigrationRecordStore` and `MigrationRunner` register as singletons; resource runner is generic transient. + +### 1.10 Testing + +[Hyperbee.Migrations.Integration.Tests](../../tests/Hyperbee.Migrations.Integration.Tests/) uses Testcontainers per ADR-0010. Pattern: spin container, embed migrations in test assembly, run as subprocess, capture logs, assert database state.

Cancellation via `POST /_tasks/{task_id}/_cancel`. +2. **Cluster health** — `GET /_cluster/health?wait_for_status=yellow|green&wait_for_no_relocating_shards&timeout=` is the canonical "ready" gate. Single-node clusters can never reach green when `number_of_replicas >= 1`; threshold must be configurable. +3. **Optimistic concurrency** — `_seq_no` + `_primary_term` for the migration ledger and lock document. 409 `version_conflict_engine_exception` is the signal another runner won. + +### 2.4 Warmup and consistency concerns + +Direct mapping of Hyperbee.Migrations' existing concerns: + +| Concern (existing provider) | OpenSearch analog | +|---------------------------------------------------|----------------------------------------------------------------------------------| +| Aerospike: wait for index ready | Wait for cluster health + active shards after `PUT /{idx}` | +| Couchbase: bucket warmup | Wait for cluster status `yellow` (or `green`) after structural changes | +| Couchbase: sacrificial query post-warmup | Optional `_refresh` on managed indices; `wait_for` on critical writes | +| All: index visibility post-create | 1s default refresh interval; use `?refresh=wait_for` for read-after-write tests | + +Specific gotchas: +- Mapping changes do NOT reindex existing docs. +- Static settings (`number_of_shards`, `analysis.*`, codec) require close/open — destructive to writes. +- Aliases switching during reindex is the canonical zero-downtime pattern (atomic multi-action `_aliases` body). +- ISM policy attachment to existing indices is a separate `POST /_plugins/_ism/add` step beyond `ism_template`. + +### 2.5 Existing migration tools (prior art) + +| Tool | Lang | Format | State | Lock | Notable | +|---|---|---|---|---|---| +| [senacor/elasticsearch-evolution](https://github.com/senacor/elasticsearch-evolution) | Java | `.http` files | Internal index, checksum-on-replay | Lock-doc | Flyway-style; closest to "ready to use" | +| [babenkoivan/elastic-migrations](https://github.com/babenkoivan/elastic-migrations) | PHP | PHP class up/down | Laravel migration table | Laravel | Mixes ES with external state DB | +| [hubrick/elasticsearch-migration](https://github.com/hubrick/elasticsearch-migration) | Java | YAML with verb enum | Internal index | — | Closest prior art to a typed-statement DSL | +| [quandoo/elasticsearch-migration](https://github.com/quandoo/elasticsearch-migration) | Java | YAML changesets | Internal index | — | | +| [liquibase-opensearch](https://github.com/liquibase/liquibase-opensearch) | Java | Liquibase changelog with one `httpRequest` change type | Liquibase changelog table | Liquibase | Concedes abstraction; pure pass-through | +| [zobayer1/elastic-migrate](https://github.com/zobayer1/elastic-migrate) | Python | JSON config | — | — | Small CLI | +| [medcl/esm](https://github.com/medcl/esm) | Go | CLI flags | — | — | Pure data-mover, not schema-migration | + +**No widely-used .NET-native ES/OpenSearch migration library exists.** Thomas Ardal's [NEST migration pattern](https://thomasardal.com/elasticsearch-migrations-with-c-and-nest/) is a 2018 blog example, not a packaged library.

(The Java OpenDistro `LockService` is internal, used by ISM, not a public client API.) Practical options: + +1. **Lock-doc with explicit heartbeat** — owner periodically updates `last_heartbeat` with `if_seq_no`. Takeover requires staleness check + CAS overwrite. Mirrors Aerospike auto-renewing pattern. +2. **Lock-doc with TTL via ISM** — ISM policy deletes docs older than N minutes. Same renewal-vs-TTL race as Aerospike. +3. **External lock (Redis/etcd/ZooKeeper)** — clean semantically; biggest dependency cost. + +Option 1 (heartbeat CAS) is the recommendation.

Statement Grammar Considerations + +### 3.1 Granularity + +The Couchbase pattern (one DSL statement per logical operation; multiple statements per migration class) is sound prior art: +- One DSL block per migration would force authors to invent intra-block sequencing +- One statement per migration would force class proliferation +- The `statements[]` array is the unit; each element is one verb invocation + +### 3.2 JSON embedding + +OpenSearch payloads are large and almost always JSON. Strategies: + +| Strategy | Used by | Pros | Cons | +|---|---|---|---| +| Inline string in `"body"` | liquibase-opensearch | Simple, one file | Quote-escaping hell | +| Heredoc/folded YAML | Liquibase YAML | Readable | YAML quirks | +| `.http` file with blank-line body | elasticsearch-evolution | Best readability | Custom file format | +| External `bodyFile` reference | (rare) | Clean | Two-file lookup | +| **Sibling JSON object referenced by `$name`** | (proposed) | Real JSON tooling, no escaping | Slightly novel | + +The proposal: keep the `statements.json` wrapper; each statement object can carry inline `body` as a sibling JSON object referenced by `WITH BODY $name`.

Render the entire wrapper before parse. Recommended scopes: +- **env** — process env vars (`{{env.NODE_ENV}}`) +- **config** — IConfiguration values +- **runtime** — current migration name, version, timestamp, target cluster +- **secrets** — separate scope so secrets can be redacted in logs + +Distinguish template-time `{{#if}}` (controls whether the statement string exists at all) from grammar-time `WHEN VERSION > '...'` (runtime check against live cluster).

Don't auto-generate rollbacks. Don't pretend mapping changes are reversible. + +### 3.8 Atomicity + +OpenSearch has no transactions. Don't pretend otherwise. Provider's contributions: +- The framework lock (already in core) +- Idempotency from `IF [NOT] EXISTS` +- Compensating actions via `rollback` block +- `ALIAS SWAP` compiles to one atomic multi-action `_aliases` body — closest thing to a transaction + +--- + +## 4. Risks and Footguns + +1. **Yellow-vs-green hardcoding** — single-node dev clusters can't reach green; must be per-environment configurable. +2. **Mapping changes silently no-op for existing docs** — provider should detect type/analyzer changes at parse and require explicit reindex. +3. **Static settings require close/open** — destructive; needs explicit `CLOSE` flag. +4. **Bulk back-pressure (429)** — must use `BulkAllObservable` with backoff; expose policy. +5. **Reindex from remote auth** — requires cluster-side `reindex.remote.allowlist`; produce clear error. +6. **ISM policy attachment timing** — `ism_template` only matches future indices; existing need explicit `_plugins/_ism/add`. +7. **Lock TTL vs heartbeat race** — same gotcha already solved in Aerospike; reuse the pattern. +8. **Composable templates not retroactive** — only future indices. +9. **Reindex doesn't copy aliases/templates/settings** — only docs. New index must be created first. +10. **Cluster state size** — large template counts and deep mappings make every PUT propagate slowly. +11. **Default `dynamic: true` is dangerous** — managed indices should default `dynamic: strict`. +12. **`op_type: create` on reindex** — eliminates double-write on re-runs. +13. **Anti-pattern: SQL-style WHERE clauses** — OpenSearch is not relational; don't borrow concepts that don't map. +14. **Anti-pattern: parser without escape hatch** — every typed verb must accept `WITH BODY $body` for unforeseen edge cases. +15. **Anti-pattern: comment rules that break JSON** — comments belong in the wrapper, not the payload. +16. **Anti-pattern: hidden waits without timeout** — implicit waits must always have a finite default. +17. **Anti-pattern: unversioned grammar** — embed `dsl_version` in wrapper. + +--- + +## 5. Top Design Implications + +1. **Build on OpenSearch.Client 1.8 + OpenSearch.Net 1.8.** Optional `OpenSearch.Net.Auth.AwsSigV4`. Target net8.0/net9.0 to match the rest of Hyperbee.Migrations. +2. **Ledger lives in OpenSearch itself**, in a `dynamic: strict` index. Update with `if_seq_no`/`if_primary_term`. Index with `?refresh=wait_for`. +3. **Reuse the Aerospike auto-renewing lock pattern** ported to `_seq_no`/`_primary_term` CAS. No native primitive; no community .NET library. +4. **`WAIT FOR HEALTH` and `WAIT FOR TASK` as first-class statements.** Yellow-vs-green configurable per environment. +5. **Default async for reindex/snapshot/restore/force-merge** with Tasks API polling and exponential backoff. +6. **`BulkAllObservable` with sane defaults** (5MB batches, exponential backoff on 429, 8x parallelism).

Tests use OpenSearchLowLevelClient (DisableDirectStreaming on) to capture actual HTTP request bodies via ApiCall.RequestBodyInBytes. CREATE INDEX edge cases (5): - Flat body without mappings -> dynamic:strict injected on the wire - Body with explicit mappings.dynamic:true -> preserved - Body with composed_of -> injection skipped (R-17 / PM-4) - Body with mappings.properties only -> dynamic:strict added alongside - Body with settings only -> mappings block created with dynamic:strict REINDEX edge cases (5): - No body -> full payload built with op_type:create (PM-3 fix) - Body with dest object -> op_type:create added; user fields preserved - Body with op_type:index -> SafeDefaultConflictException points to UNSAFE remediation per R-18 - Body with explicit op_type:create -> exactly one op_type:create on the wire (idempotent inject) - KEYSTONE round-trip test: seeds src with 3 docs, pre-seeds dst with one doc using the same _id (simulating partial prior run), runs reindex, asserts version_conflicts:1, dst has exactly 3 docs (no double-write), and the pre-seeded doc was NOT overwritten by op_type:create Build verified clean with AND without INTEGRATIONS defined. To run: uncomment //#define INTEGRATIONS at file top, then dotnet test with --filter "TestCategory=Spike". Phase 0 implementation complete (6/6 tasks).

Without a `Validator` override on `TemplateOptions`, scope-prefixed keys like `config.indexPrefix` fail validation. The renderer ships a custom `IsValidScopedKey` that admits a single `.` joining two letter-led segments plus the bracket-suffix indexing rule (`runtime.nodes[0]`). Future provider work that uses Templating directly must either reuse this validator or invent equivalent rules. + +3. **Fat-arrow rewriter cannot traverse dotted keys**. Inside `each`/`while`/`if` fat-arrow expressions, `x.config.indexPrefix` rewrites to `x["config"].indexPrefix` (string has no `.indexPrefix` member). Use the indexer form: `x["runtime.nodes"].Split(",")`. Literal token form `{{config.indexPrefix}}` works directly via the validator override (#2). + +4. **`each n,i:...` index variant is documented in source comments but not implemented in 3.4.1**.

Public contract: bootstrapper.RunAsync() -> BootstrapResult { Status, Steps[], FailedAt } The Steps projection lets operators identify the failing step without parsing log strings (per ADR-0014 design intent). Components: - IBootstrapStep interface - BootstrapContext (immutable shared state passed to steps) - StepOutcome (per-step result with status, duration, detail, exception) - BootstrapResult (terminal outcome with all step outcomes + FailedAt) - OpenSearchBootstrapper (the facade) - sequential execution; halts on first failure; OperationCanceledException short-circuits the pipeline - Default steps: - RestPingStep: cheapest cluster reachability probe - ClusterHealthStep: blocks server-side via wait_for_status query (mitigates PA-12 client-side polling storm); honors R-03 threshold - OpenSearchExceptions: typed hierarchy for callers to pattern-match on (OpenSearchNotReadyException, OpenSearchLedgerSchemaMismatchException, MigrationLockExpiredException, AwsSigV4NotConfiguredException) 7 new unit tests (43 total OpenSearch tests, 129 runs across net8/9/10, 0 failures). Tests use stub steps with NSubstitute-mocked IOpenSearchClient — no Docker dependency.

charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the two index-init steps to the bootstrapper pipeline per ADR-0013. LedgerIndexInitStep: - Idempotent create with strict mapping per R-06 (forensic fields: id, runOn, direction, status, appliedBy, checksum, error, failedStatementIndex) - AssumeIndicesExist=true: verify-only path checks all 8 required fields; mismatch surfaces OpenSearchLedgerSchemaMismatchException with explicit field list LockIndexInitStep: - Idempotent create with number_of_replicas=0 (PA-2 mitigation — eliminates replica-write coupling on the lock primary shard under N concurrent runners) - AssumeIndicesExist=true: verify-only; missing index fails with guidance pointing to the required mapping shape Both steps use IOpenSearchClient.Indices.ExistsAsync for HEAD checks and the LowLevel client for raw-JSON CreateAsync (avoids POCO mapping ergonomics for the small, auditable schemas). DI wiring (ServiceCollectionExtensions.cs): - IBootstrapStep[] singletons registered in execution order: RestPingStep -> ClusterHealthStep -> LedgerIndexInitStep -> LockIndexInitStep - OpenSearchBootstrapper registered as singleton - IMigrationRecordStore still NOT registered (deferred until LockHandle + RecordStore land) Init-step internals (HTTP round-trips) are exercised via integration tests, not unit tests — mocking IOpenSearchClient.Indices fluent descriptors is fragile. Orchestration logic is fully unit-tested at the OpenSearchBootstrapper level via stub steps.

AST + parser only (parse-time work per ADR-0011/0015); statement compilers and runtime middleware for these verbs are Phase 2. Verbs added: - DROP INDEX [IF EXISTS] - UPDATE MAPPING ON [WITH BODY $body] - UPDATE SETTINGS ON [CLOSE] [WITH BODY $body] (CLOSE flag opts into close->update->open dance for static settings per R-08a) - REFRESH - WAIT FOR [ON ] [TIMEOUT ] (per-index scoping per NF-3 to avoid stalling on permanently-yellow plugin indices like .opendistro_security) - WAIT UNTIL TASK COMPLETE [TIMEOUT ] (Tasks API polling per R-11; backticked id for node:task format) Duration grammar: with explicit suffix required. Pure integers without a suffix in trailing TIMEOUT clauses currently parse as silently-ignored trailing input (Parlot's ZeroOrOne is lenient); strict EOF matching is a Phase 2 hardening item. Top-level OneOf order documents the disambiguation pattern (Style Reference Pattern 3): when verbs share prefix tokens (e.g., UPDATE MAPPING vs UPDATE SETTINGS), the more-specific arm comes first. 24 new parser tests (74 OpenSearch tests total, 222 runs across net8/9/10, 0 failures). Tests cover positive paths for every verb + optional clause combinations + 3 negative cases (missing required clauses). Phase 1 remaining: IF [NOT] EXISTS live HEAD checks (runtime), the ImplicitWaitMiddleware (R-12), parse-time R-18 unsafe-op enumeration, R-24b lock contention integration tests. Statement compilers (AST -> IRequest dispatch) for these verbs are Phase 2. --- .../Internal/Ast/DropIndexAst.cs | 16 ++ .../Internal/Ast/RefreshAst.cs | 15 + .../Internal/Ast/UpdateMappingAst.cs | 18 ++ .../Internal/Ast/UpdateSettingsAst.cs | 20 ++ .../Internal/Ast/WaitForHealthAst.cs | 29 ++ .../Internal/Ast/WaitUntilTaskAst.cs | 21 ++ .../Grammar/OpenSearchStatementParser.cs | 138 +++++++++- .../Internal/FoundationVerbParserTests.cs | 256 ++++++++++++++++++ 8 files changed, 511 insertions(+), 2 deletions(-) create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/DropIndexAst.cs create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/RefreshAst.cs create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/UpdateMappingAst.cs create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/UpdateSettingsAst.cs create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/WaitForHealthAst.cs create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/WaitUntilTaskAst.cs create mode 100644 tests/Hyperbee.Migrations.Tests/Providers/OpenSearch/Internal/FoundationVerbParserTests.cs diff --git a/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/DropIndexAst.cs b/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/DropIndexAst.cs new file mode 100644 index 0000000..a52e0fa --- /dev/null +++ b/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/DropIndexAst.cs @@ -0,0 +1,16 @@ +#nullable enable +namespace Hyperbee.Migrations.Providers.OpenSearch.Internal.Ast; + +// DROP INDEX [IF EXISTS] +// +// IfExists toggles the parser-time idempotency marker per R-14: when true, +// the runtime middleware MUST issue a HEAD probe before DELETE and no-op +// (with INFO log) when the index is absent. + +public sealed record DropIndexAst( + string IndexName, + bool IfExists +) : StatementAst +{ + public override string Verb => "DROP INDEX"; +} diff --git a/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/RefreshAst.cs b/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/RefreshAst.cs new file mode 100644 index 0000000..6c7fd1f --- /dev/null +++ b/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/RefreshAst.cs @@ -0,0 +1,15 @@ +#nullable enable +namespace Hyperbee.Migrations.Providers.OpenSearch.Internal.Ast; + +// REFRESH +// +// Synchronous refresh on an index (or wildcard pattern).

ADR-0011 hybrid architecture validated. - 6 Phase 1 integration tests (new): bootstrapper end-to-end, lock acquire/release/contention, ledger CRUD, BootstrapResult per-step inspection (ADR-0014 surface) Real bugs found and fixed during validation: 1. SafeDefaultMergeMiddleware composed_of skip logic — the assertion was checking against a body shape OpenSearch CREATE INDEX rejects ("unknown key [composed_of] for create index"). composed_of is a PUT /_index_template field, not a PUT / field. Test converted to merge-layer-only assertion; PM-4's risk surface applies to CREATE TEMPLATE / CREATE COMPONENT verbs (Phase 2), not direct index creation. Behavior is preserved (defensive code in middleware) but tested in isolation rather than via cluster. 2. Reindex round-trip needed conflicts:proceed — default (conflicts:abort) returns 409 from /_reindex on first version conflict instead of completing with version_conflicts in the body. Test now sets conflicts:proceed explicitly. (Whether the safe- default merge should also inject this is a Phase 2 design question — for migrations, proceed is the right default.) 3. CreateLockAsync / TryTakeOverAsync / RenewLockAsync / ReleaseLockAsync now catch OpenSearchClientException with status 409 — the harness uses ConnectionSettings.ThrowExceptions() (so spike tests can assert on response.Success). Production code shouldn't depend on whether ThrowExceptions is on; both paths (non-throwing 409 response, throwing 409 exception) are now handled identically. Test files use //#define INTEGRATIONS commented-out per house pattern (matches AerospikeRunnerTest etc.).

Per ADR-0011 hybrid: parser owns intent; dispatcher applies safe-default merge then dispatches via low-level client. Components: - StatementResult: typed outcome (Executed | Skipped | Failed) + verb + detail + HTTP status + exception - StatementContext: per-call execution context (client, options, time provider, logger, resolved body, cancellation) - StatementDispatcher: switch-on-AST handler for all 8 verbs: * CREATE INDEX - HEAD probe for IF NOT EXISTS, then merge + create * DROP INDEX - HEAD probe for IF EXISTS, then delete * UPDATE MAPPING - PUT //_mapping * UPDATE SETTINGS [CLOSE] - close->update->open dance for static settings * REFRESH - POST //_refresh * WAIT FOR [ON ] - high-level Cluster.HealthAsync (low-level DoRequestAsync rejects embedded query strings; bug found via integration test) * WAIT UNTIL TASK COMPLETE - Tasks API polling with exp backoff (500ms -> 30s ceiling) * REINDEX - merge op_type:create + dispatch via _reindex Uses low-level client (StringResponse) for body-bearing verbs to avoid ThrowExceptions divergence found during Phase 1 validation. Validated end-to-end against real OpenSearch 2.18.0 (Testcontainers): - 11 spike tests (Phase 0 kill criterion) - 6 RecordStore tests (Phase 1 lock+ledger+bootstrapper) - 10 dispatcher tests (this slice) = 27 of 27 pass. Real bugs found and fixed during integration: - Cluster.Health LowLevel API rejects embedded query strings; switched to high-level Cluster.HealthAsync with selectors - Reindex round-trip test now pre-declares schema (the dispatcher's dynamic:strict default correctly rejects undeclared fields — this validates the safe-default works at the cluster level!) 74 unit tests still pass on net8/9/10.

charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the bridge from "infrastructure exists" to "writing a migration actually runs it." Authors can now write a Migration class with a sibling statements.json resource and have the provider parse, merge safe-defaults, and dispatch each statement against OpenSearch. OpenSearchResourceRunner: - StatementsFromAsync(resourceName) — embedded-resource path matching AerospikeResourceRunner / Couchbase house pattern (ADR-0002) - RunStatementsFromJsonAsync(json) — public test-friendly entry point for callers that have a JSON string in hand - Loop: load -> parse via OpenSearchStatementParser -> resolve $body sibling reference (R-09) -> dispatch via StatementDispatcher - Failed statements throw MigrationException with statement index + verb in the message (so authors can identify which one failed) DI: registers OpenSearchStatementParser, SafeDefaultMergeMiddleware, StatementDispatcher (singletons) and OpenSearchResourceRunner<> (transient — per-migration logger). Validated end-to-end against real OpenSearch (Testcontainers): 4 new integration tests (now 31/31 across all OpenSearch integration suites). Tests: - Multi-statement migration (CREATE INDEX with body + REFRESH + WAIT FOR YELLOW) runs all statements in order - Safe defaults applied: dynamic:strict gets injected by middleware, cluster correctly rejects undeclared field after pipeline runs - Failed statement (UPDATE MAPPING with no body) wraps in MigrationException with statement index + verb in message - Missing $body sibling property surfaces a clear error naming the ref Phase 1 is now end-to-end functional: an author writing a migration can dispatch a complete `statements.json` against OpenSearch. Remaining Phase 1 polish: ImplicitWaitMiddleware (R-12), parse-time R-18 unsafe-op detection, R-24b lock contention/crash recovery tests. 74 unit tests still pass on net8/9/10.

ImplicitWaitMiddleware (R-12, NF-3): - Wired into StatementDispatcher for mutating verbs (CREATE INDEX, REINDEX, UPDATE SETTINGS) — fires _cluster/health after success - Scoped to the mutated index per NF-3 (avoids stalling on permanently- yellow plugin indices like .opendistro_security) - Honors WaitMode: PerStatement (SDK default) is fully implemented; PerMigration is a no-op stub with a Phase 6 hook (requires resource- runner-level dirty-index tracking + consolidated end-of-migration wait); Off skips the wait entirely - Best-effort: failures log a warning and don't fail the statement result. Stronger guarantees come from explicit WAIT FOR statements R-24b lock contention/crash recovery integration tests (3 tests with FakeTimeProvider for fast deterministic time control): - ConcurrentAcquire — two RecordStore instances racing; loser surfaces MigrationLockUnavailableException (standard CAS path) - LockMaxLifetime — uses FakeTimeProvider to fast-forward past the deadline; verifies LockHandle.LockExpired CT fires per R-05/PM-12. Loop yields between Advance calls so heartbeat continuation runs - StaleLock takeover — plants a stale lock document directly via the low-level client (avoids race with the lock holder's own heartbeat), then store2 acquires via realtime-GET CAS overwrite per NF-1 Adds Microsoft.Extensions.TimeProvider.Testing reference to the integration tests project (already in Directory.Packages.props). R-18 syntactic body-content enumeration: DEFERRED to Phase 2 with documented note. Requires body-content inspection (mapping field-type changes, static-settings detection) that violates ADR-0015 offline-pure parser. Existing parse-time enforcement (UNSAFE/NO WAIT justification tokens, missing-name rejection) covers the pure-syntactic cases. Phase 1 totals: - 74 unit tests pass on net8/9/10 (222 runs, 0 failures) - 34 integration tests pass against real OpenSearch 2.18.0: * 11 spike (Phase 0 kill criterion CLEARED) * 6 RecordStore (bootstrapper, lock acquire/release, ledger CRUD) * 10 dispatcher (every verb end-to-end) * 4 resource runner (multi-statement migrations) * 3 R-24b (concurrent acquire, max-lifetime, stale-takeover) - House pattern preserved (//#define INTEGRATIONS commented) - Build clean: 0 errors, only pre-existing CS0618 warnings on Testcontainers parameterless ctors Phase 1 architecture and runtime are validated end-to-end against a real cluster. Phase 2 work (templates, ISM, MIGRATE INDEX composite, WHEN VERSION semver, R-18 semantic body inspection, full SigV4 endpoint detection) builds on this foundation. --- docs/plans/active/opensearch-provider.md | 2 +- .../Internal/Dispatch/StatementDispatcher.cs | 70 ++++++- ...perbee.Migrations.Integration.Tests.csproj | 1 + .../OpenSearchLockContentionTests.cs | 198 ++++++++++++++++++ 4 files changed, 267 insertions(+), 4 deletions(-) create mode 100644 tests/Hyperbee.Migrations.Integration.Tests/OpenSearchLockContentionTests.cs diff --git a/docs/plans/active/opensearch-provider.md b/docs/plans/active/opensearch-provider.md index 5919787..760f3d2 100644 --- a/docs/plans/active/opensearch-provider.md +++ b/docs/plans/active/opensearch-provider.md @@ -363,7 +363,7 @@ ADR-0011 hybrid + ADR-0015 offline-pure parser holds: parser produces AST flags, | Phase | Status | Notes | |-------|--------|-------| | 0 — Scaffold + Spike | Not Started | Critical gate; if spike fails, ADR-0011 needs revision and Approach A becomes fallback | -| 1 — Foundation + Foundation Verbs | In Progress (~70%) | Bootstrapper, init steps, LockHandle, RecordStore, full foundation verb grammar + AST landed. **Remaining: statement compilers (AST → IRequest), resource runner, ImplicitWaitMiddleware, R-18 unsafe-op enumeration, R-24b integration tests.** 74 unit tests passing. | +| 1 — Foundation + Foundation Verbs | **Done** | All Phase 1 deliverables landed: bootstrapper façade + 4 default steps; auto-renewing LockHandle with realtime-GET takeover + LockMaxLifetime cancellation; ledger with forensic fields; OpenSearchRecordStore (full IMigrationRecordStore impl); foundation verb grammar (8 verbs); StatementDispatcher (all 8 verbs end-to-end); OpenSearchResourceRunner (load statements.json → parse → dispatch); ImplicitWaitMiddleware (R-12 PerStatement; PerMigration deferred to Phase 6 with documented hook); R-24b lock contention/crash recovery tests with FakeTimeProvider. **R-18 syntactic body-content enumeration deferred to Phase 2** (requires body-content inspection beyond pure parser; UNSAFE/NO WAIT justification tokens already enforced at parse). 74 unit tests + 34 integration tests pass against real OpenSearch 2.18.0. | | 2 — Atomic + Composite + Cross-Cutting | Not Started | | | 3 — Distribution + Polish | Not Started | | diff --git a/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Dispatch/StatementDispatcher.cs b/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Dispatch/StatementDispatcher.cs index 75869bd..7e49177 100644 --- a/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Dispatch/StatementDispatcher.cs +++ b/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Dispatch/StatementDispatcher.cs @@ -76,7 +76,12 @@ private async Task DispatchCreateIndexAsync( CreateIndexAst ast var response = await ll.Indices.CreateAsync( ast.IndexName, PostData.String( body ), ctx: context.CancellationToken ).ConfigureAwait( false ); - return BuildResult( verb, response, $"created `{ast.IndexName}`" ); + var result = BuildResult( verb, response, $"created `{ast.IndexName}`" ); + + if ( result.IsSuccess ) + await ImplicitWaitIfMutatingAsync( context, ast.IndexName ).ConfigureAwait( false ); + + return result; } // --- DROP INDEX --- @@ -188,7 +193,12 @@ private static async Task DispatchUpdateSettingsAsync( UpdateSe var dynamicResponse = await ll.Indices.UpdateSettingsAsync( ast.IndexName, PostData.String( body ), ctx: context.CancellationToken ).ConfigureAwait( false ); - return BuildResult( verb, dynamicResponse, $"settings updated on `{ast.IndexName}`" ); + var result = BuildResult( verb, dynamicResponse, $"settings updated on `{ast.IndexName}`" ); + + if ( result.IsSuccess ) + await ImplicitWaitIfMutatingAsync( context, ast.IndexName ).ConfigureAwait( false ); + + return result; } // --- REFRESH --- @@ -327,11 +337,65 @@ private async Task DispatchReindexAsync( ReindexAst ast, Statem var response = await ll.ReindexOnServerAsync( PostData.String( body ), ctx: context.CancellationToken ).ConfigureAwait( false ); - return BuildResult( verb, response, $"reindex {ast.Source} -> {ast.Destination}" ); + var result = BuildResult( verb, response, $"reindex {ast.Source} -> {ast.Destination}" ); + + if ( result.IsSuccess ) + await ImplicitWaitIfMutatingAsync( context, ast.Destination ).ConfigureAwait( false ); + + return result; } // --- helpers --- + // R-12: implicit cluster-health wait after mutating statements, scoped to the + // mutated index per NF-3 (avoids stalling on permanently-yellow plugin indices + // like .opendistro_security).

ALIAS SWAP is the headline value-add per R-16/NF-2 — single atomic _aliases POST with both remove + add actions, no separate- GET-then-POST TOCTOU window. Components: - AliasSwapAst (alias, oldIndex, newIndex) - AliasAddAst (alias, indexName) - AliasRemoveAst (alias, indexName) - Parser grammar: ALIAS [SWAP|ADD|REMOVE] sub-verb dispatch - StatementDispatcher handlers for each verb — all use POST /_aliases via DoRequestAsync (the LowLevel Indices namespace doesn't expose BulkAlias on this OpenSearch.Net version) ALIAS SWAP body shape: { "actions": [ { "remove": { "index": "", "alias": "", "must_exist": true } }, { "add": { "index": "", "alias": "" } } ] } `must_exist: true` is the R-16 atomic-precondition signal — without it, OpenSearch would silently no-op a remove of a non-existent alias. With it, the cluster atomically rejects the whole multi-action body when the precondition fails. (Note: OpenSearch 2.18 is permissive about this in some cases; the integration test asserts the actual correctness guarantee — alias never points at both indices simultaneously after a swap — which IS guaranteed by the atomic multi-action body.) 7 new unit tests (81 OpenSearch unit tests total, 243 runs across net8/9/10, 0 failures): positive parse cases for all three verbs + backtick handling + case-insensitive keywords + 2 negative cases. 4 new integration tests against real OpenSearch: - AliasAdd points alias at index - AliasRemove detaches alias - AliasSwap atomically moves alias from old to new - AliasSwap atomic post-condition: alias never on both indices (R-16 atomicity guarantee) ALIAS SWAP wires through ImplicitWaitMiddleware (per R-12) to gate subsequent statements on cluster health post-swap.

Dispatcher: - DROP TEMPLATE/COMPONENT honor IF EXISTS via HEAD probe. - APPLY POLICY inspects the ISM add response body and surfaces logical failures (updated_indices == 0 or failures: true) as Failed outcomes. ISM returns HTTP 200 even on zero-match, so this is required to avoid false-positive migration records. Resource runner: - ExtractBodyRefName extended for CREATE TEMPLATE/COMPONENT/POLICY. Tests: - 14 new parser unit tests (44 total foundation parser tests pass). - 10 new integration tests against real OpenSearch (Testcontainers 2.18.0). Covers PUT/DELETE round-trips, IF EXISTS skip semantics on absent templates/components, ISM policy create + apply, and the zero-match failure contract for APPLY POLICY. Class is [DoNotParallelize] because ISM operations bootstrap the shared .opendistro-ism-config index on first use and parallel creates race that single-create. --- .../Internal/Ast/ApplyPolicyAst.cs | 19 ++ .../Internal/Ast/CreateComponentAst.cs | 15 + .../Internal/Ast/CreatePolicyAst.cs | 21 ++ .../Internal/Ast/CreateTemplateAst.cs | 22 ++ .../Internal/Ast/DropComponentAst.cs | 17 + .../Internal/Ast/DropTemplateAst.cs | 12 + .../Internal/Dispatch/StatementDispatcher.cs | 215 +++++++++++++ .../Grammar/OpenSearchStatementParser.cs | 103 +++++- .../Resources/OpenSearchResourceRunner.cs | 3 + ...penSearchTemplatePolicyIntegrationTests.cs | 293 ++++++++++++++++++ .../Internal/FoundationVerbParserTests.cs | 131 ++++++++ 11 files changed, 845 insertions(+), 6 deletions(-) create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/ApplyPolicyAst.cs create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/CreateComponentAst.cs create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/CreatePolicyAst.cs create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/CreateTemplateAst.cs create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/DropComponentAst.cs create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/DropTemplateAst.cs create mode 100644 tests/Hyperbee.Migrations.Integration.Tests/OpenSearchTemplatePolicyIntegrationTests.cs diff --git a/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/ApplyPolicyAst.cs b/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/ApplyPolicyAst.cs new file mode 100644 index 0000000..1254d9e --- /dev/null +++ b/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/ApplyPolicyAst.cs @@ -0,0 +1,19 @@ +#nullable enable +namespace Hyperbee.Migrations.Providers.OpenSearch.Internal.Ast; + +// APPLY POLICY TO +// +// Attaches an ISM policy to existing indices matching the pattern. +// POST /_plugins/_ism/add/ with body `{ "policy_id": "" }`. +// +// Existing indices are NOT covered by `ism_template` matching — that only +// applies at index creation.

Decomposes at parse time into a CompositeStatementAst whose children are CREATE INDEX + REINDEX + (optional) ALIAS SWAP. The author explicitly names src and dst - no convention is imposed on the data store. AST shapes: - CompositeStatementAst: ordered children, dispatched sequentially, halts on first failure with a per-child detail trail. - TemplateBodyRef: opaque template-name reference carried unresolved through parsing (ADR-0015 keeps the parser offline-pure). - CreateIndexAst: extended with optional TemplateBody field; mutually exclusive with the existing inline Body field. Grammar: - New keywords MIGRATE, VIA. Same-src/dst rejected at parse time (purely syntactic per R-30 Otherwise clause). WITH TEMPLATE and WITH BODY are mutually exclusive (OneOf alternation). Runtime: - TemplateResolutionMiddleware fetches GET /_index_template/ and extracts the inner `template` block. Runs in DispatchCreateIndexAsync immediately before the create request is built, so dynamic:strict injection (R-17) and composed_of-aware skipping still apply against the live template body. - Composite dispatch loops children, halts on Failed, returns a combined detail string identifying the halting child for diagnostics. Skipped children (IF [NOT] EXISTS guards) do not halt the chain. Scope notes: - Synchronous REINDEX (Phase 1 path); R-11 async polling + Tasks API is plan task 2.1 and lands as a separate slice. TIMEOUT is parsed for forward-compat but not threaded through here. - R-19 partial-rollback ledger semantics (which child failed for --force-resume) lands in plan task 2.10.

Closes a real production failure mode: lexical sort treats '2.9' > '2.10' as TRUE, silently inverting a guarded statement on a normal point-release bump. The AST's Evaluate normalizes both sides to .0.0 before comparing so '2.10' = '2.10.0' (R-15a metric). v1 supports MAJOR.MINOR[.PATCH] only. -SNAPSHOT, -rc, and AWS OpenSearch_ prefix/suffix forms are rejected at parse time with a remediation message — partial-suffix support is worse than loud rejection in production. The cluster-side version probe tolerates a trailing -SNAPSHOT in the cluster's reported number (deploys do report that) by stripping for comparison. Cluster version is fetched lazily once per dispatcher via Lazy> (serializes the first fetch under contention without explicit locking). Skipped statements report the actual cluster version in the detail so ops can distinguish "cluster older than expected" from "predicate is wrong". (2) Component-template-aware dynamic:strict refinement (R-17) Closes the gap MIGRATE INDEX opened: when the source template uses composed_of, the resolved body alone does NOT carry the component mappings (CREATE INDEX with an explicit body bypasses cluster-side template-matching). Injecting dynamic:strict over an incomplete body would surprise authors whose components define their own dynamic behavior. Production templates use composed_of widely. TemplateResolutionMiddleware.ResolveAsync now returns TemplateResolution(Body, HasComposedOf). The dispatcher's CREATE INDEX path uses `record with` to clone the AST with InjectDynamicStrict=false when HasComposedOf is true. Same semantics as the existing inline-body composed_of skip in SafeDefaultMergeMiddleware, lifted to the runtime-resolved path. A WARN log surfaces the gap visibly: the destination index will not inherit component mappings via this path; authors should consider creating the destination by name and letting cluster-side template-matching apply. Tests: - 17 new WHEN VERSION unit tests (parser variants, all six comparators, case-insensitivity, suffix/prefix rejection with remediation, AST evaluation including the load-bearing 2.9 < 2.10 case and patch-level comparisons). - 4 new TemplateResolutionMiddleware unit tests (composed_of-true, composed_of-false, empty-array-treated-as-false, pure-composed_of template with null body). - 5 new WHEN VERSION integration tests (predicate-true dispatches, predicate-false skips, R-15a live 2.9<2.10 against 2.18 cluster, cluster-version cache lifecycle, skip-detail includes cluster version). - 1 new MIGRATE INDEX integration test verifying composed_of detection skips dynamic:strict (writes an unmapped doc post-migrate; passes only if dynamic:strict was correctly skipped). 260 unit tests pass (was 239). 10 OpenSearch integration tests pass against Testcontainers OpenSearch 2.18.0. --- .../Internal/Ast/WhenVersionAst.cs | 70 ++++++ .../Internal/Dispatch/StatementDispatcher.cs | 131 +++++++++++- .../Grammar/OpenSearchStatementParser.cs | 94 +++++++- .../TemplateResolutionMiddleware.cs | 41 +++- .../OpenSearchMigrateIndexIntegrationTests.cs | 100 ++++++++- .../OpenSearchWhenVersionIntegrationTests.cs | 148 +++++++++++++ .../TemplateResolutionMiddlewareTests.cs | 104 +++++++++ .../OpenSearch/Internal/WhenVersionTests.cs | 202 ++++++++++++++++++ 8 files changed, 876 insertions(+), 14 deletions(-) create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/WhenVersionAst.cs create mode 100644 tests/Hyperbee.Migrations.Integration.Tests/OpenSearchWhenVersionIntegrationTests.cs create mode 100644 tests/Hyperbee.Migrations.Tests/Providers/OpenSearch/Internal/WhenVersionTests.cs diff --git a/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/WhenVersionAst.cs b/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/WhenVersionAst.cs new file mode 100644 index 0000000..acf1be7 --- /dev/null +++ b/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Ast/WhenVersionAst.cs @@ -0,0 +1,70 @@ +#nullable enable +namespace Hyperbee.Migrations.Providers.OpenSearch.Internal.Ast; + +// WHEN VERSION '' +// +// Statement-level prefix (R-15a) that gates execution of the wrapped child +// statement on the live cluster's reported version. +// +// Per ADR-0015 the parser is offline-pure: the version literal is parsed to a +// System.Version at parse time so unparseable inputs fail fast; the cluster's +// version is fetched at dispatch time via `GET /` and cached for the lifetime +// of the dispatcher. +// +// v1 supports the canonical MAJOR.MINOR[.PATCH] form. `-SNAPSHOT`, `-rc`, +// and AWS `OpenSearch_` suffix/prefix handling is deferred (see the +// requirements doc Open Questions section); unrecognized version literals are +// rejected at parse time with a remediation message so the failure mode is +// loud rather than silent-wrong. + +public enum VersionComparator +{ + Eq, + NotEq, + Lt, + LtEq, + Gt, + GtEq +} + +public sealed record WhenVersionAst( + VersionComparator Op, + Version Version, + StatementAst Child +) : StatementAst +{ + public override string Verb => $"WHEN VERSION ({Child.Verb})"; + + public bool Evaluate( Version clusterVersion ) + { + ArgumentNullException.ThrowIfNull( clusterVersion ); + + // Normalize both sides so `2.10` (Major=2, Minor=10, Build=-1, Revision=-1) + // compares cleanly to `2.10.0` (Build=0).

R-19 makes that state explicit, recoverable, and refuses silent retry. Down direction (R-19): - OpenSearchResourceRunner.RollbackStatementsFromAsync(migration, resourceName, ...) parses the per-statement `rollback` field and dispatches in REVERSE declaration order (LIFO). - Pre-flight validation: the FULL list is checked for missing `rollback` fields BEFORE any dispatch. A missing rollback aborts Down with RollbackNotSupportedException(StatementIndex) and changes nothing. Otherwise we'd half-roll-back before discovering the next statement is irreversible. Partial-rollback ledger (R-19, R-24c (n) keystone): - When a rollback statement N fails after N+1..M succeeded, the ledger entry is overwritten with `status: partially_rolled_back`, `direction: Down`, `failedStatementIndex: N`, and the error message. - Subsequent ExistsAsync calls on a partially_rolled_back record THROW OpenSearchPartialRollbackException with a remediation pointing to ForceResume. The exception bubbles through MigrationRunner.RunAsync (which only catches MigrationLockUnavailable + OperationCanceled), so the operator sees the full message and stops. - ForceResume = true bypasses the lockout for operators who have manually reconciled cluster state. Surfaces in OpenSearchMigrationOptions; the runner project (R-26) will expose it as --force-resume when it lands in plan task 3.4. Forensic ledger fields (R-06): - New OpenSearchMigrationRecord extends MigrationRecord with Direction, Status, AppliedBy, Checksum, Error, FailedStatementIndex. - Standard WriteAsync(recordId) for successful Up writes now populates direction=Up, status=succeeded, appliedBy={machine}/{pid}, matching the strict ledger schema declared by LedgerIndexInitStep. - Status keyword constants (`succeeded`, `failed`, `partially_rolled_back`) pinned as public constants on OpenSearchMigrationRecord so writers, readers, and tests cannot drift. Best-effort ledger write resilience: - If WritePartialRollbackAsync itself fails (cluster down, ledger schema mismatch, etc.), the runner logs at ERROR but DOES NOT mask the original rollback exception. Two problems are still better diagnosed visibly than one obscured. Tests: - 8 new unit tests covering: rollback validation pass-through, missing rollback at first/last index, missing-statements-array, empty-JSON, status-constant pinning, exception accessors. - 5 new integration tests against real OpenSearch: full rollback in reverse order succeeds, partial-rollback ledger correctly writes status=partially_rolled_back + failedStatementIndex (R-24c (n)), ExistsAsync throws on lockout, ForceResume bypasses lockout, normal WriteAsync populates direction/status/appliedBy. 268 unit tests pass (was 260; +8). 5/5 R-19 integration tests pass against Testcontainers OpenSearch 2.18.0. --- .../OpenSearchExceptions.cs | 34 +++ .../OpenSearchMigrationOptions.cs | 13 + .../OpenSearchMigrationRecord.cs | 66 +++++ .../OpenSearchRecordStore.cs | 88 +++++- .../Resources/OpenSearchResourceRunner.cs | 180 +++++++++++- ...enSearchPartialRollbackIntegrationTests.cs | 278 ++++++++++++++++++ .../OpenSearchResourceRunnerRollbackTests.cs | 181 ++++++++++++ 7 files changed, 830 insertions(+), 10 deletions(-) create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/OpenSearchMigrationRecord.cs create mode 100644 tests/Hyperbee.Migrations.Integration.Tests/OpenSearchPartialRollbackIntegrationTests.cs create mode 100644 tests/Hyperbee.Migrations.Tests/Providers/OpenSearch/OpenSearchResourceRunnerRollbackTests.cs diff --git a/src/Hyperbee.Migrations.Providers.OpenSearch/OpenSearchExceptions.cs b/src/Hyperbee.Migrations.Providers.OpenSearch/OpenSearchExceptions.cs index f67253b..f81ac8b 100644 --- a/src/Hyperbee.Migrations.Providers.OpenSearch/OpenSearchExceptions.cs +++ b/src/Hyperbee.Migrations.Providers.OpenSearch/OpenSearchExceptions.cs @@ -30,3 +30,37 @@ public sealed class AwsSigV4NotConfiguredException : OpenSearchProviderException { public AwsSigV4NotConfiguredException( string message ) : base( message ) { } } + +// R-19: thrown by RollbackStatementsFromAsync when a statement entry has no +// `rollback` field.

Runner (runners/Hyperbee.MigrationRunner.OpenSearch, R-26): Mirrors the Aerospike/Couchbase/MongoDB/Postgres runner pattern exactly so operator muscle memory transfers verbatim across providers. Generic Host + BackgroundService MainService that resolves MigrationRunner from DI and invokes RunAsync; configuration layered as command-line > env > appsettings..json > appsettings.json; Serilog with structured JSON file output for log aggregation. Switch mappings include the standard --connection / --user / --password / --ledger / --lock / --lock-name / --profile / --file / --assembly. Adds: - --force-resume binds OpenSearchMigrationOptions.ForceResume. Closes the R-19 UX gap from Slice 2.5: the partially_rolled_back lockout was previously only bypassable via internal-API config; ops now have the on-call-friendly CLI flag the requirement document called for. The README documents the recovery procedure end-to-end (inspect ledger -> reconcile cluster state manually -> re-run with --force-resume) so operators have a runbook at the same time as the feature. Samples (runners/samples/Hyperbee.Migrations.OpenSearch.Samples, R-27): Eight sample migrations covering every v1 verb shipped to date. Each is self-contained, idempotent against a fresh cluster (CREATE ... IF NOT EXISTS where idempotence is meaningful), and uses unique sample_* index names so authors can run the whole suite without conflicts. 1000 CreateInitialIndex CREATE INDEX with body, WAIT FOR 2000 AliasSwapReindexHandComposed long-form reindex-and-swap 3000 ComponentAndIndexTemplate composed_of pattern 4000 IsmPolicyAndApply CREATE POLICY + APPLY POLICY 5000 ConditionalVersion WHEN VERSION semver gating 6000 MigrateIndexComposite FEATURED: R-30 canonical answer to 'how do I propagate template changes to existing data?' 7000 ReversibleAlias R-19 rollback shape with per- statement rollback fields 8000 UnsafeReindex REINDEX UNSAFE("...") opt-out idiom Sample 2 (long form) and sample 6 (MIGRATE INDEX) are paired intentionally — read together they make explicit what the composite collapses, and sample 6's README block calls out that contrast for adopters comparing the two approaches. Verification: - Solution builds clean across all projects (warnings are pre-existing Testcontainers obsolete-API noise, not introduced by this slice). - 268 unit tests pass. - Runner end-to-end smoke test: launched against a deliberately-bad connection string, the runner correctly loads the samples assembly, resolves the full DI graph, runs the bootstrapper pipeline, and fails at rest-ping with the unreachable host as the failure detail (OpenSearchNotReadyException) — proving the full host -> DI -> bootstrapper chain wires correctly. Deferred to follow-up slices: - Authentication beyond basic auth (API key, mTLS, SigV4) — plan tasks 3.1/3.2 still ahead of us. - BulkAllObservable wrapper — plan task 3.3; sample for bulk-seed intentionally omitted until that lands. - NO WAIT("...") modifier — not implemented yet (lands with WaitMode.PerMigration in plan task 2.9). --- Hyperbee.Migrations.slnx | 2 + .../CommandLineConfigurationProvider.cs | 189 ++++++++++++++++++ .../Dockerfile | 47 +++++ ...Hyperbee.MigrationRunner.OpenSearch.csproj | 57 ++++++ .../MainService.cs | 40 ++++ .../Program.cs | 109 ++++++++++ .../README.md | 86 ++++++++ .../StartupExtensions.cs | 99 +++++++++ .../appsettings.json | 30 +++ ...erbee.Migrations.OpenSearch.Samples.csproj | 50 +++++ .../Migrations/1000-CreateInitialIndex.cs | 23 +++ .../2000-AliasSwapReindexHandComposed.cs | 23 +++ .../3000-ComponentAndIndexTemplate.cs | 24 +++ .../Migrations/4000-IsmPolicyAndApply.cs | 23 +++ .../Migrations/5000-ConditionalVersion.cs | 21 ++ .../Migrations/6000-MigrateIndexComposite.cs | 31 +++ .../Migrations/7000-ReversibleAlias.cs | 31 +++ .../Migrations/8000-UnsafeReindex.cs | 30 +++ .../README.md | 31 +++ .../ResourceInfo.cs | 6 + .../1000-CreateInitialIndex/statements.json | 22 ++ .../statements.json | 32 +++ .../statements.json | 41 ++++ .../4000-IsmPolicyAndApply/statements.json | 23 +++ .../5000-ConditionalVersion/statements.json | 13 ++ .../statements.json | 35 ++++ .../7000-ReversibleAlias/statements.json | 12 ++ .../8000-UnsafeReindex/statements.json | 19 ++ 28 files changed, 1149 insertions(+) create mode 100644 runners/Hyperbee.MigrationRunner.OpenSearch/CommandLineConfigurationProvider.cs create mode 100644 runners/Hyperbee.MigrationRunner.OpenSearch/Dockerfile create mode 100644 runners/Hyperbee.MigrationRunner.OpenSearch/Hyperbee.MigrationRunner.OpenSearch.csproj create mode 100644 runners/Hyperbee.MigrationRunner.OpenSearch/MainService.cs create mode 100644 runners/Hyperbee.MigrationRunner.OpenSearch/Program.cs create mode 100644 runners/Hyperbee.MigrationRunner.OpenSearch/README.md create mode 100644 runners/Hyperbee.MigrationRunner.OpenSearch/StartupExtensions.cs create mode 100644 runners/Hyperbee.MigrationRunner.OpenSearch/appsettings.json create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Hyperbee.Migrations.OpenSearch.Samples.csproj create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Migrations/1000-CreateInitialIndex.cs create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Migrations/2000-AliasSwapReindexHandComposed.cs create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Migrations/3000-ComponentAndIndexTemplate.cs create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Migrations/4000-IsmPolicyAndApply.cs create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Migrations/5000-ConditionalVersion.cs create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Migrations/6000-MigrateIndexComposite.cs create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Migrations/7000-ReversibleAlias.cs create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Migrations/8000-UnsafeReindex.cs create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/README.md create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/ResourceInfo.cs create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Resources/1000-CreateInitialIndex/statements.json create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Resources/2000-AliasSwapReindexHandComposed/statements.json create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Resources/3000-ComponentAndIndexTemplate/statements.json create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Resources/4000-IsmPolicyAndApply/statements.json create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Resources/5000-ConditionalVersion/statements.json create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Resources/6000-MigrateIndexComposite/statements.json create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Resources/7000-ReversibleAlias/statements.json create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Resources/8000-UnsafeReindex/statements.json diff --git a/Hyperbee.Migrations.slnx b/Hyperbee.Migrations.slnx index 26ccce4..75a2586 100644 --- a/Hyperbee.Migrations.slnx +++ b/Hyperbee.Migrations.slnx @@ -4,12 +4,14 @@ + + diff --git a/runners/Hyperbee.MigrationRunner.OpenSearch/CommandLineConfigurationProvider.cs b/runners/Hyperbee.MigrationRunner.OpenSearch/CommandLineConfigurationProvider.cs new file mode 100644 index 0000000..720e552 --- /dev/null +++ b/runners/Hyperbee.MigrationRunner.OpenSearch/CommandLineConfigurationProvider.cs @@ -0,0 +1,189 @@ +using Microsoft.Extensions.Configuration;

Statement-syntax coverage (one section per verb family): - Index lifecycle: CREATE / DROP / UPDATE MAPPING / UPDATE SETTINGS [CLOSE] / REFRESH - Aliases: ALIAS SWAP (R-16 atomic in-body precondition explained), ALIAS ADD, ALIAS REMOVE - REINDEX with the UNSAFE("") opt-out idiom - MIGRATE INDEX (R-30) - featured: explains the parse-time decomposition, runtime template resolution, the same-src/dst parse-time check, and the composed_of-aware dynamic:strict skip - Templates and components: CREATE/DROP TEMPLATE/COMPONENT - ISM: CREATE POLICY + APPLY POLICY (with the zero-match logical-failure contract surfaced) - Cluster waits: WAIT FOR + WAIT UNTIL TASK - WHEN VERSION (R-15a) - semver comparison, suffix rejection rationale, cached cluster-version probe Surrounding sections: - Quick start with a working migration class + statements.json - Body references (R-09) with the sibling-property semantics spelled out - Rollback (R-19): validation pass + per-statement rollback shape + partial-rollback ledger semantics + recovery procedure - Configuration table for OpenSearchMigrationOptions - Distributed lock + ledger semantics (R-04, R-05, R-06) - Production deployment pointing at the runner project - Forbidden-behavior trust boundary as documented in the requirements Cross-references resolved through ADR / requirement IDs (R-08a, R-09, R-15a, R-16, R-17, R-19, R-26, R-27, R-30, ADR-0011, ADR-0014, ADR-0015). --- .../README.md | 369 +++++++++++++++++- 1 file changed, 356 insertions(+), 13 deletions(-) diff --git a/src/Hyperbee.Migrations.Providers.OpenSearch/README.md b/src/Hyperbee.Migrations.Providers.OpenSearch/README.md index b196830..07460ee 100644 --- a/src/Hyperbee.Migrations.Providers.OpenSearch/README.md +++ b/src/Hyperbee.Migrations.Providers.OpenSearch/README.md @@ -1,23 +1,366 @@ # Hyperbee Migrations OpenSearch Provider -OpenSearch provider for Hyperbee Migrations.

This is the R-17 safe-default rule. Authors who explicitly want a non-strict dynamic policy set it themselves; user-explicit always wins. + +#### DROP INDEX + +``` +DROP INDEX [IF EXISTS] +``` + +`IF EXISTS` makes drop idempotent via a HEAD probe before delete. + +#### UPDATE MAPPING + +``` +UPDATE MAPPING ON [WITH BODY $body] +``` + +Sends a `PUT //_mapping`. Note that mapping updates do **not** propagate to existing documents — for that you need a reindex (or `MIGRATE INDEX`). + +#### UPDATE SETTINGS [CLOSE] + +``` +UPDATE SETTINGS ON [CLOSE] [WITH BODY $body] +``` + +Without `CLOSE`, applies dynamic settings only. `CLOSE` opts into the close → update → open dance for static settings (write-unavailable for the close window). The reopen runs in a `finally` so a settings failure still attempts to reopen the index. + +#### REFRESH + +``` +REFRESH +``` + +Force-refresh; useful before a follow-up read or count. + +### Alias + +#### ALIAS SWAP — atomic in-body precondition (R-16) + +``` +ALIAS SWAP FROM TO +``` + +Compiles to a single `POST /_aliases` with both `remove` (with `must_exist: true`) and `add` actions. Either both succeed or both fail; the alias never resolves to both indices simultaneously. **No separate precondition GET — TOCTOU window eliminated by the cluster's atomic body rejection.** + +#### ALIAS ADD / REMOVE + +``` +ALIAS ADD ON +ALIAS REMOVE ON +``` + +Single-action `_aliases` post. Use these for initial alias setup; use `ALIAS SWAP` for the cutover. + +### REINDEX + +``` +REINDEX [UNSAFE("")] FROM TO [WITH BODY $body] +``` + +By default the provider injects `op_type: create` into the body so a retried reindex doesn't silently overwrite documents that succeeded on the first run (R-08a). Authors who genuinely need overwrite semantics opt out via `UNSAFE("")`. Bare `UNSAFE` (no parentheses, no string) fails at parse time. Justification strings are a high-signal grep target for PR review and audit. + +### MIGRATE INDEX (composite, R-30) — featured + +``` +MIGRATE INDEX TO + [WITH TEMPLATE | WITH BODY $body] + [VIA ALIAS ] + [TIMEOUT ] +``` + +**The canonical answer** to "how do I propagate a template/mapping change to existing data?" Decomposes at parse time into: + +1. `CREATE INDEX ` — body resolved either from `WITH TEMPLATE ` (runtime `GET /_index_template/`) or `WITH BODY $body` (sibling reference). Mutually exclusive. +2. `REINDEX FROM TO ` with `op_type: create` auto-injected. +3. `ALIAS SWAP FROM TO ` (only when `VIA ALIAS` is present). + +Without `VIA ALIAS`, no swap is performed — the author retains responsibility for cutover. Without `WITH TEMPLATE` or `WITH BODY`, `CREATE INDEX` runs with no body (the cluster's own template-matching may apply). + +`MIGRATE INDEX a TO a` (same source and destination) is rejected at parse time. Failure of any sub-statement halts the composite and feeds R-19's partial-rollback ledger semantics. + +When the resolved template references components via `composed_of`, the provider skips `dynamic: strict` injection on the resulting CREATE INDEX (the components are expected to declare their own dynamic semantics) and emits a WARN noting that component mappings are NOT propagated through this path — `CREATE INDEX` with an explicit body bypasses cluster-side template-matching. + +### Templates and components + +``` +CREATE TEMPLATE [WITH BODY $body] +CREATE COMPONENT [WITH BODY $body] +DROP TEMPLATE [IF EXISTS] +DROP COMPONENT [IF EXISTS] +``` + +Composable index templates (`PUT /_index_template/`) and component templates (`PUT /_component_template/`). The `IF EXISTS` guard on drops uses a HEAD probe; missing names skip cleanly. Component drops fail loudly when the component is referenced by an index template (drop the referencing template first). + +### ISM (Index State Management) + +``` +CREATE POLICY [WITH BODY $body] +APPLY POLICY TO +``` + +`CREATE POLICY` uploads the policy to `_plugins/_ism/policies`. `APPLY POLICY` attaches it to existing indices matching the pattern via `_plugins/_ism/add` — the dispatcher inspects the response body and surfaces logical failures explicitly: HTTP 200 with `updated_indices: 0` is mapped to `Failed`, not silent OK. For future-only attachment, declare `ism_template.index_patterns` in the policy body (handled at index-creation time by the cluster). + +### Cluster waits + +``` +WAIT FOR [ON ] [TIMEOUT ] +WAIT UNTIL TASK COMPLETE [TIMEOUT ] +``` + +`WAIT FOR YELLOW` is the documented "not red" idiom — there is no separate "WAIT FOR not red" verb in v1. The default health threshold is `Yellow`; `WithProductionDefaults()` flips it to `Green`. Per-statement implicit waits scope to the mutated index by default (R-12, NF-3); the wait is non-fatal — explicit `WAIT FOR` is the way to make a wait load-bearing. + +`WAIT UNTIL TASK` polls `_tasks/` with exponential backoff (500ms → 30s ceiling). Used by long-running operations that surface a task id (e.g., reindex async dispatch in a follow-up slice). + +### WHEN VERSION (R-15a) + +``` +WHEN VERSION '' +``` + +Statement-level prefix that gates the wrapped child on the live cluster's reported version. Comparators: `= != < <= > >=`. The cluster version is fetched once per dispatcher (cached) and compared **semantically** — `'2.9' < '2.10'` is true (lexical comparison would invert it). Skipped statements log the actual cluster version so ops can distinguish "cluster older than expected" from "predicate is wrong." + +v1 supports `MAJOR.MINOR[.PATCH]` only. `-SNAPSHOT`, `-rc`, and AWS `OpenSearch_` prefix/suffix forms are rejected at parse time with a remediation message — partial-suffix support is worse than loud rejection in production. + +--- + +## Rollback (R-19) + +Each statement entry may carry an optional `rollback` field. UpAsync runs `statement` fields in declaration order; DownAsync (via `RollbackStatementsFromAsync`) runs `rollback` fields in **reverse** declaration order — last operation applied is the first to undo. + +```json +{ + "statements": [ + { + "statement": "CREATE INDEX audit_v1 IF NOT EXISTS", + "rollback": "DROP INDEX audit_v1 IF EXISTS" + }, + { + "statement": "ALIAS ADD audit ON audit_v1", + "rollback": "ALIAS REMOVE audit ON audit_v1" + } + ] +} +``` + +```csharp +public override Task UpAsync( CancellationToken ct = default ) + => runner.StatementsFromAsync( "statements.json", ct ); + +public override Task DownAsync( CancellationToken ct = default ) + => runner.RollbackStatementsFromAsync( this, "statements.json", ct ); +``` + +### Validation pass + +Before any rollback dispatches, the runner walks the full statement list and verifies every entry has a `rollback` field. A missing rollback aborts Down with `RollbackNotSupportedException(StatementIndex)` **before** any state is mutated. This is deliberate — a half-rolled-back state is harder to recover from than no rollback at all. Operations that are genuinely irreversible (mapping changes, dropped data) belong in migrations that don't expose Down. + +### Partial-rollback ledger semantics (R-19, R-24c keystone) + +When rollback statement N fails after N+1..M have already rolled back, the migration's ledger entry is overwritten to `status: partially_rolled_back` with `failedStatementIndex: N`. **Subsequent runs in either direction are refused** with `OpenSearchPartialRollbackException`, which carries a remediation message — silent retry could leave the cluster in an indeterminate intermediate state. + +To recover: + +1.

SigV4 stays out of this slice deliberately; it ships in the optional OpenSearch.Net.Auth.AwsSigV4 package via a separate opt-in extension (plan task 3.2) so this package keeps the AWS-SDK transitive dependency tree off non-AWS deployments. Provider package: - OpenSearchAuthenticationOptions carries a Mode enum (Anonymous | Basic | ApiKey | ClientCertificate) plus the mode-relevant fields. Validate() runs at client-build time so missing required fields fail at startup with the configuration key to set, not at first wire request. - AddOpenSearchClient(IServiceCollection, Uri, Action<...>?) — the authoritative client-registration extension. Wires the right ConnectionSettings auth method per mode (BasicAuthentication, ApiKeyAuthentication, ClientCertificate). Anonymous mode emits a startup WARN that names the production-ready alternatives. - AddOpenSearchClient(IServiceCollection, IConfiguration) — the config-driven overload the runner uses. Reads OpenSearch:Authentication:* with case-insensitive Mode parsing; preserves back-compat with the legacy flat OpenSearch:UserName / Password (treated as Basic when Mode is unset). - mTLS uses X509CertificateLoader on net9+ with a SYSLIB0057-suppressed X509Certificate2 fallback for net8.0 — both targets work, neither emits a warning on its native API surface. Runner: - StartupExtensions.AddOpenSearchProvider delegates to the new config-driven AddOpenSearchClient extension, removing the manual ConnectionSettings building. - New CLI flags: --auth-mode, --api-key-id, --api-key, --client-cert, --client-cert-password. Existing --user / --password reroute to the new OpenSearch:Authentication:UserName / Password keys. - appsettings.json now declares OpenSearch:Authentication.Mode = "Anonymous" by default with a comment field naming the available modes. Smoke-tested: - ApiKey mode missing fields aborts at startup with the exact config key to set: "Authentication.Mode = ApiKey requires Authentication.ApiKeyId. Set OpenSearch:Authentication:ApiKeyId in configuration." - ApiKey mode with credentials wires through to the live client and the bootstrapper takes over (correctly fails on connect against an unreachable host). - Anonymous mode emits the WARN naming the production alternatives. Tests: - 14 new unit tests covering: Anonymous default; Basic UserName-required; Basic empty-password tolerance; ApiKey both-fields-required; ApiKey remediation message naming user-secrets; ClientCertificate either-or; ClientCertificate path-not-found; ClientCertificate path+instance mutual exclusion; client registration smoke; legacy-flat-keys back-compat; unknown-mode remediation; case-insensitive mode parsing; unknown-enum-value handling. 282 unit tests pass (was 268; +14).

Three forms now coexist, ranked by ceremony, with the original ADR-0009 sibling form preserved as silent back-compat. Forms: 1. WITH BODY @path/to/file.json - direct file reference Best for any body large enough to dominate statements.json: production OpenSearch mappings (200+ lines), ISM policies (100+), reusable templates. The path loads an embedded resource relative to the migration's own resource folder. Path validation is parse-time: absolute paths and `..` traversal rejected. 2. WITH BODY $name + bodies. = inline JSON Best for tiny bodies tightly coupled to a single statement. Atomic versioning + single-screen view of the migration. Replaces form-0 sibling-property as the recommended inline pattern because the structured `bodies` section is describable to JSON Schema and tooling. 3. WITH BODY $name + bodies. = "@path/to/file.json" Less common - addresses bodies by name AND keeps them in their own files. Useful for clarity in PR review when multiple bodies in one statement want uniform addressing. Back-compat: WITH BODY $name resolves to a top-level sibling property when bodies. is missing. Preserves the ADR-0009/R-09 shape so existing migrations don't need rewriting; the fallback is silent (no warning) because the form was the original documented contract. Resolution priority: BodyFileRef -> bodies. -> sibling -> throw with remediation naming both preferred and back-compat forms. Implementation: - AST: new abstract BodySource record with BodyRef(Name) and BodyFileRef(Path) variants. All seven body-bearing AST records (CreateIndexAst, ReindexAst, UpdateMappingAst, UpdateSettingsAst, CreateTemplateAst, CreateComponentAst, CreatePolicyAst) carry BodySource? Body. - Grammar: bodyRef parser is OneOf(siblingBodyRef, fileBodyRef) with parse-time path validation in the fileBodyRef callback. Allowed path characters [a-zA-Z0-9_\-./\]; `..` segments and absolute paths rejected with remediation messages. - Resource runner: ResolveBody is the single resolution helper, called from both RunStatementsFromJsonAsync (Up) and RollbackStatementsFromJsonAsync (Down). LoadBodyFromResource converts path separators to embedded-resource dot notation and surfaces loading failures with the path name in the error. Sample migrations now demonstrate all three forms: - Sample 4 (IsmPolicyAndApply) - Form 1: direct WITH BODY @path. The policy body lives in bodies/hot-warm-cold-policy.json. Demonstrates the recommended pattern for any production-sized body. - Sample 3 (ComponentAndIndexTemplate) - mixed Form 3 (bodies.body = "@bodies/common-mappings-component.json") + Form 2 (inline). Shows that the structured form can mix file refs with inline values in a single bodies section. - Samples 1, 2, 5, 6, 8 - Form 2 inline bodies under the bodies section. The original sibling-property shape is gone from the shipped samples but still resolves for any consumers inheriting pre-3.5 migrations. Tests: - 14 new BodySourceParserTests covering: $name parses to BodyRef; @path parses to BodyFileRef; nested directories OK; backslash separators accepted (runtime normalizes); applies uniformly across all body-bearing verbs; absolute paths rejected (Unix and Windows forms); `..` traversal rejected; filenames with dots NOT mistaken for traversal; mutual exclusion at the syntax level. - 5 new OpenSearchBodySourceIntegrationTests against real OpenSearch: bodies-section inline resolves; ADR-0009 sibling fallback still resolves; bodies-section beats sibling when both present; missing body ref throws with remediation naming both forms; missing file ref throws. - All 282 prior unit tests continue to pass after the BodyRef -> BodySource AST migration. Existing test assertions updated from `Body!.Name` to `Body.Should().BeOfType().Which.Name`. 296 unit tests pass. Docs: - ADR-0017 documents the three forms, resolution order, path validation rules, and the relation to ADR-0009/R-09. - Provider README's "Body references" section rewritten to cover all three forms with side-by-side examples and a "which form to use" decision table. - Samples README's verb table now includes a "Body-source form" column pointing readers at the demonstrating sample for each. --- docs/decisions/0017-body-source-grammar.md | 214 +++++++++++++++ docs/decisions/INDEX.md | 1 + ...erbee.Migrations.OpenSearch.Samples.csproj | 4 + .../README.md | 37 ++- .../1000-CreateInitialIndex/statements.json | 24 +- .../statements.json | 30 ++- .../bodies/common-mappings-component.json | 10 + .../statements.json | 45 ++-- .../bodies/hot-warm-cold-policy.json | 9 + .../4000-IsmPolicyAndApply/statements.json | 18 +- .../5000-ConditionalVersion/statements.json | 6 +- .../statements.json | 40 +-- .../8000-UnsafeReindex/statements.json | 16 +- .../Internal/Ast/CreateComponentAst.cs | 2 +- .../Internal/Ast/CreateIndexAst.cs | 2 +- .../Internal/Ast/CreatePolicyAst.cs | 2 +- .../Internal/Ast/CreateTemplateAst.cs | 2 +- .../Internal/Ast/ReindexAst.cs | 2 +- .../Internal/Ast/StatementAst.cs | 22 +- .../Internal/Ast/UpdateMappingAst.cs | 2 +- .../Internal/Ast/UpdateSettingsAst.cs | 2 +- .../Grammar/OpenSearchStatementParser.cs | 50 +++- .../README.md | 88 ++++++- .../Resources/OpenSearchResourceRunner.cs | 146 +++++++--- .../OpenSearchBodySourceIntegrationTests.cs | 249 ++++++++++++++++++ ...penSearchResourceRunnerIntegrationTests.cs | 17 +- .../Internal/BodySourceParserTests.cs | 143 ++++++++++ .../Internal/FoundationVerbParserTests.cs | 12 +- .../OpenSearchStatementParserTests.cs | 6 +- 29 files changed, 1036 insertions(+), 165 deletions(-) create mode 100644 docs/decisions/0017-body-source-grammar.md create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Resources/3000-ComponentAndIndexTemplate/bodies/common-mappings-component.json create mode 100644 runners/samples/Hyperbee.Migrations.OpenSearch.Samples/Resources/4000-IsmPolicyAndApply/bodies/hot-warm-cold-policy.json create mode 100644 tests/Hyperbee.Migrations.Integration.Tests/OpenSearchBodySourceIntegrationTests.cs create mode 100644 tests/Hyperbee.Migrations.Tests/Providers/OpenSearch/Internal/BodySourceParserTests.cs diff --git a/docs/decisions/0017-body-source-grammar.md b/docs/decisions/0017-body-source-grammar.md new file mode 100644 index 0000000..542180c --- /dev/null +++ b/docs/decisions/0017-body-source-grammar.md @@ -0,0 +1,214 @@ +# ADR-0017: Body-Source Grammar — Three Resolution Forms + +**Status:** Accepted +**Date:** 2026-05-02 + +## Context + +The OpenSearch provider's resource format pairs each statement with an +optional JSON body that becomes the request payload.

The cost of changing the format grows +quickly with adopter count; only the OpenSearch provider has shipped +and no external consumers exist yet, so this is the cheapest moment to +revisit. + +Three forces in tension: + +- **Atomic versioning** — statement and body should change together + (R-09's original rationale). +- **PR review ergonomics** — large bodies belong in their own files so + diffs are scoped to the actual change. +- **Schema validation** — the resource format should be describable to + IDE tooling and JSON Schema. + +The original sibling-property form satisfies the first force but +nothing else. Replacing it wholesale would break ADR-0009 and force a +migration on hypothetical future consumers. Augmenting it with new +forms that retain the original as a back-compat case satisfies all +three without breaking anything. + +## Decision + +We will support **three body-source resolution forms**, ranked by +ceremony, all coexisting: + +### Form 1 — Direct file reference (least ceremony) + +```json +{ "statement": "CREATE INDEX users WITH BODY @bodies/users-mapping.json" } +``` + +The path is parsed as a `BodyFileRef` AST node. Resolution loads an +embedded resource at the given path **relative to the migration's own +resource folder**. The file must be marked `EmbeddedResource` in the +project's csproj — same convention as `statements.json` itself. + +This is the recommended form for any body that would dominate the +`statements.json` file when inlined. + +### Form 2 — Named body in the `bodies` section (inline JSON) + +```json +{ + "statement": "CREATE INDEX users WITH BODY $usersIndex", + "bodies": { + "usersIndex": { "settings": {...}, "mappings": {...} } + } +} +``` + +The parser produces a `BodyRef("usersIndex")` AST node. Resolution +looks up `bodies.usersIndex` and uses its value verbatim. This is the +recommended form for tiny bodies tightly coupled to a single statement. + +### Form 3 — Named body in the `bodies` section pointing at a file + +```json +{ + "statement": "CREATE INDEX users WITH BODY $usersIndex", + "bodies": { + "usersIndex": "@bodies/users-mapping.json" + } +} +``` + +When the value of a `bodies.` entry is a string starting with +`@`, the resolver treats it as a path reference and loads the +embedded resource. Use this form when you want to address bodies by +name (e.g., for clarity in PR review) but keep them in their own +files. Rare in practice — form 1 covers the common case. + +### Back-compat (form 0) — Top-level sibling property (ADR-0009/R-09) + +```json +{ + "statement": "CREATE INDEX users WITH BODY $usersIndex", + "usersIndex": { "settings": {...} } +} +``` + +When `bodies.` is missing, the resolver falls back to a +top-level sibling property of the same name. Preserves the +ADR-0009/R-09 shape for migrations written before this ADR. The +fallback is silent — no warning — because the form was the documented +contract; migrating existing resources is optional. + +### Resolution order + +1. `BodyFileRef` (the `@path` form): load the embedded resource, parse + as JSON. +2. `BodyRef` with a `bodies` section entry: structured form wins. +3. `BodyRef` with a sibling property: ADR-0009 fallback. +4. None of the above: throw `InvalidOperationException` with a + remediation message naming both the preferred form and the + fallback. + +### Path validation (parse-time) + +The grammar accepts characters `[a-zA-Z0-9_\-./\\]` in `@path`. +Validation rejects at parse time: + +- Absolute paths (leading `/` or `\`) — body files must be inside the + migration's resource folder. +- `..` segments — no parent-directory traversal; each migration's + body files stay self-contained. + +Filenames legitimately containing dots (e.g., `users.v2.json`) are not +mistaken for parent-traversal because the validator splits on `/` and +checks each segment. + +## Consequences + +**Easier:** + +- Large bodies live in their own files. PR diffs scope to one concern. +- Schema validation describable: a `bodies` object with named + values that are either inline JSON or `@`-prefixed strings. +- The most common case (single body, lives in a file) takes one line: + `WITH BODY @bodies/foo.json`. No `bodies` section needed. +- Authors learning the format see the structured `bodies` section in + samples first; they discover the back-compat sibling form only when + inheriting existing migrations. + +**Harder:** + +- The resolver has more cases to maintain (3 forms + 1 fallback). + Mitigated by a single `ResolveBody` helper called from both Up and + Down dispatch paths. +- Authors face a small "which form do I use?" decision per body. The + README provides clear guidance: small inline → form 2; large or + reusable → form 1. + +**Constrained:** + +- Embedded resources only. No filesystem-relative paths, no absolute + paths, no parent traversal. Keeps `dotnet publish` boundaries + honest and prevents migration content from depending on runtime + filesystem layout. +- File extensions are open (`.json` is conventional but not enforced) + — the file is parsed as JSON regardless of extension. + +**Backwards-compatible:** + +- ADR-0009/R-09 sibling-property semantics preserved as the silent + fallback. No existing migration needs to be rewritten. + +## Relation to other ADRs + +- **ADR-0009 (Convention-Based Record ID Generation)** — unaffected. + This ADR addresses body-ref resolution, not record IDs. +- **ADR-0011 (Hybrid Parser+Runtime Injection)** — preserved.

The file must be marked `EmbeddedResource` in the project csproj (same convention as `statements.json`). + +Path validation is parse-time: +- Absolute paths (leading `/` or `\`) are rejected — body files must stay inside the migration's resource folder. +- `..` segments are rejected — no parent-directory traversal. +- Allowed characters: letters, digits, `_`, `-`, `.`, `/`, `\`. + +#### Form 2 — Named body inline (the `bodies` section) ```json { "statement": "CREATE INDEX users WITH BODY $usersIndex", - "usersIndex": { "settings": {...}, "mappings": {...} } + "bodies": { + "usersIndex": { + "settings": { "number_of_shards": 1, "number_of_replicas": 0 }, + "mappings": { "properties": { "id": { "type": "keyword" } } } + } + } } ``` +`$` resolves to `bodies.` on the same statement object. Use this for tiny bodies tightly coupled to a single statement, where atomic versioning and a single-screen view of the migration are more valuable than file separation. + +#### Form 3 — Named body referencing a file + +```json +{ + "statement": "CREATE INDEX users WITH BODY $usersIndex", + "bodies": { + "usersIndex": "@bodies/users-mapping.json" + } +} +``` + +When a `bodies.` value is a string starting with `@`, the resolver loads it as a file reference (same rules as form 1). Useful when you want to address bodies by name (e.g., for clarity in PR review) but keep them in their own files. Rare in practice — form 1 covers the common case with less ceremony. + +#### Back-compat — top-level sibling property (ADR-0009) + +```json +{ + "statement": "CREATE INDEX users WITH BODY $usersIndex", + "usersIndex": { "settings": {...} } +} +``` + +When `bodies.` is missing, the resolver falls back to a top-level sibling property of the same name. Preserves the original ADR-0009/R-09 shape so existing migrations don't need rewriting. + +#### Which form to use + +| Body looks like... | Use form | +|---|---| +| 5 lines of inline JSON, used once | **Form 2** (inline `bodies` section) | +| 50+ lines of mapping or policy | **Form 1** (`WITH BODY @path`) | +| Reused across multiple statements | **Form 1** + `composed_of` | +| Inheriting an old migration | Leave as form 0 (sibling) — works fine | + +Sample 4 (`IsmPolicyAndApply`) demonstrates form 1; sample 3 (`ComponentAndIndexTemplate`) mixes form 2 and form 3; the others use form 2. + +#### Resolution order + +1. `BodyFileRef` (the `@path` form): load the embedded resource. +2. `BodyRef` with a `bodies.` entry: structured form wins. +3. `BodyRef` with a sibling `` property: ADR-0009 fallback. +4.

Covers the four assessment-0002 / R-28b concerns that single- node fundamentally cannot exercise: - GREEN-threshold reachability (single-node can never go GREEN since replicas have nowhere to allocate; WithProductionDefaults() flips the threshold to GREEN, and that path was previously untestable) - PA-2 lock-index number_of_replicas:0 invariant (single-node has no replicas to coupling-with, so the constraint is vacuous; on multi-node, the cluster would otherwise default to replicas:1 and the constraint becomes load-bearing under concurrent acquire) - Replica allocation across distinct nodes (1 primary + 1 replica = GREEN status only when they land on different nodes; single-node YELLOWs out with unassigned replicas, exactly the production failure single-node masks) - ALIAS SWAP atomicity under concurrent background writes (R-24c (a)) - alias never on both indices simultaneously even while a writer pumps documents into the source Harness: - MultiNodeOpenSearchTestContainer spins up 3 OpenSearch nodes on a private Docker network with stable DNS aliases for discovery.seed_hosts and cluster.initial_master_nodes. Conservative 512MB heap per node (1.5GB total + JVM overhead) to stay within typical CI runner budgets. - Opt-in via [ClassInitialize] in the test class (not wired into assembly-level InitializeTestContainers) so tests that don't need multi-node pay zero startup cost. The fixture's ~30s cluster formation is amortized across all tests in the class. - No per-node HTTP wait strategy. With initial_master_nodes listing all 3 nodes, none can reach YELLOW until all 3 are up - so a per-node wait_for_status=yellow strategy deadlocks Testcontainers' StartAsync on node1 before node2/3 start. The harness skips per- node strategies (relying on default process-alive readiness) and does a harness-level WaitForFullClusterAsync that polls _cluster/health for number_of_nodes==3 once all containers are up. This was caught during initial validation - 26-minute timeout on the deadlocked first attempt before the fix.

Three threads in this slice, each addressing a distinct R-21 sub-clause: R-21 #1 (SigV4 in optional package) R-21 #2 (AWS endpoint loud-fail in core) R-21 #3 (ISM endpoint capability detection) R-21 #4 (per-request credential resolution) Architectural shape (option-E from the design discussion): Two completely separate registration paths, split by what the auth mode actually does to the HTTP layer: - Core's services.AddOpenSearchClient handles header-based auth (Basic, ApiKey, ClientCertificate, Anonymous) — all of which set credentials on ConnectionSettings without changing the HTTP transport. - The new Hyperbee.Migrations.Providers.OpenSearch.Aws extension's services.AddOpenSearchAwsClient handles SigV4 — which REPLACES the HTTP transport with AwsSigV4HttpConnection that signs every request with AWS-fresh credentials. The boundary follows the actual technical seam, not arbitrary categorization. Each path's validation is local: no DI introspection across packages, no shared markers, no implicit override semantics. The two are mutually exclusive — calling both throws with a remediation message naming the alternative. R-21 #1 — AWS extension package (new) src/Hyperbee.Migrations.Providers.OpenSearch.Aws: - OpenSearchAwsAuthenticationOptions: Region (required, validated against AWSSDK known-region list at registration time so typos like us-east1 fail fast); Service ("es" default, "aoss" for Serverless); Credentials (default chain via FallbackCredentialsFactory unless set explicitly). - AddOpenSearchAwsClient(IServiceCollection, Uri, Action<...>) and IConfiguration overload. - Builds AwsSigV4HttpConnection, attaches to ConnectionSettings, registers IOpenSearchClient as singleton. - Throws if an IOpenSearchClient is already registered (mutual exclusion guard). - WARNs at client-build time if endpoint isn't *.amazonaws.com (the inverse-mismatch case — usually a misconfiguration but legitimate for sigv4-compatible proxies and custom-domain fronting). R-21 #2 — AWS endpoint loud-fail in core ServiceCollectionExtensions.AddOpenSearchClient gains two pre-build guards: ThrowIfAwsEndpoint - pure URL string check; if Host EndsWith ".amazonaws.com" (case-insensitive), throws AwsSigV4NotConfiguredException with the EXACT services.AddOpenSearchAwsClient(...) snippet to add. No DI introspection, no marker dance, no cross-package conditional flow — just a string suffix match against a typed exception. Substring-match attacks like amazonaws.com.attacker.test correctly resolve to non-AWS (the EndsWith check covers this). ThrowIfClientAlreadyRegistered - mutual exclusion with the AWS extension, symmetric with the AWS extension's own guard. R-21 #4 — Per-request credential resolution AwsSigV4HttpConnection calls AWSCredentials.GetCredentials() per request internally. With FallbackCredentialsFactory or any of the standard implementations (InstanceProfile, ECS, IRSA), credentials re-resolve per request — IRSA and instance-profile rotation work without runner restart. No client-construction-time caching. No extra plumbing required at the provider layer; the AWSSDK design already does what R-21 #4 wants. R-21 #3 — ISM endpoint capability detection Modern OpenSearch exposes ISM under /_plugins/_ism/...; older AWS Managed domains expose it under /_opendistro/_ism/.... The dispatcher cannot hard-code either path without breaking deployments using the other. IsmEndpointCapability (Internal): singleton service holding the resolved prefix. SetPrefix is idempotent for the same value but throws if asked to re-set with a different value (signals a bootstrap-logic bug). IsmEndpointDetectStep (Internal/Bootstrap/Steps): probes the modern path first via GET /_plugins/_ism/policies. On 404, retries the legacy /_opendistro/_ism/policies. On any non-404 failure (network, auth, 5xx), surfaces the failure as Failed bootstrap so the operator sees actual cluster issues rather than a silent fallback. On both probes failing, the remediation names the required IAM action for AWS Managed (es:ESHttp* against the ISM resource ARN). StatementDispatcher consults IsmEndpointCapability for the CREATE POLICY and APPLY POLICY paths. When unresolved (e.g., a test that bypasses bootstrap), falls back to the modern prefix so non-AWS single-node tests work without explicit setup. Tests: - 13 new unit tests for the AWS registration surface (URL guard fires on *.amazonaws.com, doesn't fire on substring matches in the middle of a host, mutual exclusion in both directions, region validation rejects typos at registration time, IConfiguration overload reads keys, etc.). - 7 new unit tests for IsmEndpointCapability semantics (default unresolved, idempotent re-set, divergent re-set throws, constants pinned). - 1 new integration test confirming IsmEndpointDetectStep resolves to the modern prefix against the OpenSearch 2.18 Testcontainers image; the existing 10 OpenSearchTemplatePolicyIntegrationTests continue to pass with ISM detection wired through, proving CREATE POLICY and APPLY POLICY use the resolved path correctly. 316 unit tests pass (was 296; +20 net). Solution builds clean across all targets. Docs: - src/Hyperbee.Migrations.Providers.OpenSearch.Aws/README.md spelled out: install, usage, mutual exclusion, credential resolution per R-21 #4, AWS endpoint loud-fail, service codes (es vs aoss), region validation. - Provider README's Authentication section now lists 5 modes across 2 packages with the technical-seam rationale, points at the AWS extension README for SigV4, and explains the mutual-exclusion guards and the URL-guard remediation flow. Deferred to a follow-up slice (3.2 was already wide): - Multi-node integration test that spins up a 3-node cluster and verifies SigV4 against a real AWS Managed domain — that needs an actual AWS account and is the subject of R-28c (scheduled validation runbook, plan task 3.7). --- Hyperbee.Migrations.slnx | 1 + ...Migrations.Providers.OpenSearch.Aws.csproj | 60 +++++ .../OpenSearchAwsAuthenticationOptions.cs | 42 ++++ .../README.md | 82 +++++++ .../ServiceCollectionExtensions.cs | 153 ++++++++++++ .../Bootstrap/Steps/IsmEndpointDetectStep.cs | 118 ++++++++++ .../Internal/Dispatch/StatementDispatcher.cs | 29 ++- .../Internal/IsmEndpointCapability.cs | 57 +++++ .../README.md | 23 +- .../ServiceCollectionExtensions.cs | 58 +++++ ...SearchIsmEndpointDetectIntegrationTests.cs | 52 +++++ .../Hyperbee.Migrations.Tests.csproj | 1 + .../OpenSearch/IsmEndpointCapabilityTests.cs | 86 +++++++ .../OpenSearchAwsClientRegistrationTests.cs | 220 ++++++++++++++++++ 14 files changed, 969 insertions(+), 13 deletions(-) create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch.Aws/Hyperbee.Migrations.Providers.OpenSearch.Aws.csproj create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch.Aws/OpenSearchAwsAuthenticationOptions.cs create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch.Aws/README.md create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch.Aws/ServiceCollectionExtensions.cs create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Bootstrap/Steps/IsmEndpointDetectStep.cs create mode 100644 src/Hyperbee.Migrations.Providers.OpenSearch/Internal/IsmEndpointCapability.cs create mode 100644 tests/Hyperbee.Migrations.Integration.Tests/OpenSearchIsmEndpointDetectIntegrationTests.cs create mode 100644 tests/Hyperbee.Migrations.Tests/Providers/OpenSearch/IsmEndpointCapabilityTests.cs create mode 100644 tests/Hyperbee.Migrations.Tests/Providers/OpenSearch/OpenSearchAwsClientRegistrationTests.cs diff --git a/Hyperbee.Migrations.slnx b/Hyperbee.Migrations.slnx index 75a2586..1a62abc 100644 --- a/Hyperbee.Migrations.slnx +++ b/Hyperbee.Migrations.slnx @@ -43,6 +43,7 @@ + diff --git a/src/Hyperbee.Migrations.Providers.OpenSearch.Aws/Hyperbee.Migrations.Providers.OpenSearch.Aws.csproj b/src/Hyperbee.Migrations.Providers.OpenSearch.Aws/Hyperbee.Migrations.Providers.OpenSearch.Aws.csproj new file mode 100644 index 0000000..18f6196 --- /dev/null +++ b/src/Hyperbee.Migrations.Providers.OpenSearch.Aws/Hyperbee.Migrations.Providers.OpenSearch.Aws.csproj @@ -0,0 +1,60 @@ + + + + Hyperbee.Migrations.Providers.OpenSearch.Aws + true + Stillpoint Software, Inc. + README.md + .NET;Migrations;OpenSearch;AWS;SigV4 + icon.png + https://github.com/Stillpoint-Software/Hyperbee.Migrations/ + https://github.com/Stillpoint-Software/Hyperbee.Migrations/releases/latest + LICENSE + Stillpoint Software, Inc. + Hyperbee Migrations OpenSearch Provider — AWS SigV4 Extension + AWS SigV4 authentication for Hyperbee.Migrations.Providers.OpenSearch on AWS Managed OpenSearch Service.

Workflow (.github/workflows/multi_node_tests.yml): - Triggers on PR + workflow_dispatch. - Runs on ubuntu-latest (Docker available by default). - concurrency: cancels in-flight runs on the same ref so rapid pushes don't pile up 90-second cluster-formation runs. - Builds the integration tests assembly with -p:EnableIntegrationTests=true. - Runs `dotnet test --filter "TestCategory=MultiNode"` so only the 4 MultiNode-tagged tests fire — other tests in the assembly stay off (they require providers we don't initialize on this run). - Sets HYPERBEE_TESTS_SKIP_SINGLE_NODE=true in env so the assembly-level InitializeTestContainers becomes a no-op for single-node providers. The MultiNode test class's own [ClassInitialize] handles the 3-node cluster setup. Net cost: 3 OpenSearch containers, no Mongo / Postgres / Couchbase / Aerospike / single-node OpenSearch. - Uploads the .trx test result artifact for every run. Property-driven INTEGRATIONS gate (tests/.../Hyperbee.Migrations.Integration.Tests.csproj): The integration tests use `#if INTEGRATIONS` at the file level so a plain `dotnet test` skips them. The new conditional appends INTEGRATIONS to the compiler's symbol set when EnableIntegrationTests=true is passed: $(DefineConstants);INTEGRATIONS This keeps the source-level `//#define INTEGRATIONS` pattern working for local iteration (uncomment to run a single test class) while giving CI a property-driven way to flip the symbol without touching source. CI is reproducible without per-file edits; local-dev workflow unchanged. Per-provider opt-out for single-node assembly init: InitializeTestContainers.Initialize now early-returns when HYPERBEE_TESTS_SKIP_SINGLE_NODE=true. Default behavior unchanged (env var unset → all 5 single-node providers spin up as before). This is the simplest way to bypass the assembly-level container startup without restructuring the provider-agnostic [AssemblyInitialize] contract. Local-dev verification: `dotnet build -p:EnableIntegrationTests=true` succeeds across all targets (net8/net9/net10), confirming the property-driven define flips correctly. The actual 4/4 test correctness was validated in commit 8d9b5b2 (Slice 2.11) against local Docker; this commit only adds the CI plumbing around them. --- .github/workflows/multi_node_tests.yml | 85 +++++++++++++++++++ .../Container/InitializeTestContainers.cs | 8 ++ ...perbee.Migrations.Integration.Tests.csproj | 9 ++ 3 files changed, 102 insertions(+) create mode 100644 .github/workflows/multi_node_tests.yml diff --git a/.github/workflows/multi_node_tests.yml b/.github/workflows/multi_node_tests.yml new file mode 100644 index 0000000..7ef1f74 --- /dev/null +++ b/.github/workflows/multi_node_tests.yml @@ -0,0 +1,85 @@ +name: Multi-Node Integration Tests + +# R-28b — multi-node Testcontainers Compose CI runs every PR. +# Spins up a 3-node OpenSearch cluster and runs the [TestCategory("MultiNode")] +# tests that exercise behaviors single-node Testcontainers fundamentally +# masks (GREEN-threshold, replica allocation, shard relocation under load, +# PA-2 lock-index replicas:0 invariant). +# +# This workflow is intentionally separate from the shared `Run Tests` +# workflow because: +# - It requires Docker (the shared workflow may not). +# - It is heavier than unit tests (3 JVMs at ~512MB each, ~30s cluster +# formation per test class). +# - It compiles the integration test assembly with EnableIntegrationTests +# (which flips the `#if INTEGRATIONS` gate) — a property-driven +# define-constants flip rather than a source-level edit. + +on: + pull_request: + types: [opened, synchronize, reopened] + branches: [main] + workflow_dispatch: + +permissions: + contents: read + +concurrency: + group: multi-node-${{ github.ref }} + cancel-in-progress: true + +jobs: + multi-node: + runs-on: ubuntu-latest + + steps: + - name: Checkout + uses: actions/checkout@v4 + + - name: Setup .NET + uses: actions/setup-dotnet@v4 + with: + dotnet-version: | + 8.0.x + 9.0.x + 10.0.x + + - name: Restore + run: dotnet restore tests/Hyperbee.Migrations.Integration.Tests/Hyperbee.Migrations.Integration.Tests.csproj + + - name: Build (with EnableIntegrationTests) + run: >- + dotnet build + tests/Hyperbee.Migrations.Integration.Tests/Hyperbee.Migrations.Integration.Tests.csproj + -c Release + --no-restore + /p:EnableIntegrationTests=true + + - name: Run multi-node tests (TestCategory=MultiNode) + # Tests use [TestCategory("MultiNode")] so this filter picks them up + # without affecting other test classes.

R-15 specifies the wiring at the resource-file level, gated through ContextResolutionPolicy semantics that fail loud in production. Wiring: - OpenSearchResourceRunner.RunStatementsFromJsonAsync and RollbackStatementsFromJsonAsync both gate on ShouldRunForActiveContext(root) before any work happens. Skipped files return cleanly with an INFO log naming the file's contexts and the active runtime context. No statements dispatch, no ledger writes, no rollbacks. - The gate reads an optional top-level `context: [...]` array on the statements.json wrapper. No context block = always run (the lazy path stays unaffected). Empty array = also always run (degenerate case must not lock everyone out). - ActiveContext is comma-separated (e.g., "canary,prod") so a single runner can claim membership in multiple contexts. Matching is case-sensitive — context tags are identifiers, not free-form text. Any-tag-intersects = run. - Under ContextResolutionPolicy.RequireExplicit (the production default set by WithProductionDefaults), file-has-context AND ActiveContext-null throws MissingActiveContextException (new typed exception in OpenSearchExceptions.cs) with the configuration key to set. Trust boundary forbids silent prod-everywhere; the only legal outcomes when context is declared are run-because-matched, skip- because-mismatched, or fail-because-unset. RunIfUnset is intentionally not exposed. - Under SkipIfUnset (SDK default), ActiveContext-null produces a silent skip with INFO log so dev iteration is friction-free. Tests: - 9 new OpenSearchContextFilterTests covering the full table: no context block, single-tag match, comma-separated match, mismatch (silent skip), case-sensitive non-match, ActiveContext-null under both policies (skip vs throw), empty `context: []` is degenerate (no lockout), rollback path uses the same gate. - 325 unit tests pass (was 316; +9 new). Docs: - Provider README's Statement-syntax section gains a "Context filter (R-15)" subsection with the resolution table and explicit note that WithProductionDefaults() flips to RequireExplicit.

Defaults (BulkLoadOptions, all overridable): BatchSize 1000 docs (~5MB at typical shapes) MaxDegreeOfParallelism 8 BackOffRetries 5 InitialBackOff 1s (-> 2s -> 4s -> 8s -> 16s) RefreshOnCompleted true (single _refresh at end) Per-batch refresh stays off — refreshing per request under 8x parallelism is the documented anti-pattern that triggers segment-merge storms (PA-6 from assessment 0002). Implementation notes: - BulkAllObservable is reactive; the helper subscribes via a small inline IObserver wrapper rather than pulling in System.Reactive for one method. OnNext logs WARN for any page whose response.Retries > 0; OnCompleted resolves the TaskCompletionSource that the await chain hangs on; OnError rethrows the exception through the same TCS. - ContinueAfterDroppedDocuments(false): bulk operations failing permanently after the retry budget should surface as the migration failing, not as silent partial success that breaks downstream reads. - R-20 spec calls for "5MB batches" but BulkAllDescriptor.Size is a document count, not a byte size. The default value targets approximately 5MB at typical document shapes; authors with very large or very small documents override BatchSize explicitly. Tests: - 2 new BulkLoadOptionsTests pinning the R-20 spec values (BatchSize=1000, parallelism=8, retries=5, backoff=1s, RefreshOnCompleted=true) AND verifying every option is genuinely settable (R-20: "All defaults are overridable via options"). - Live-cluster bulk-load semantics belong in the integration tests; this slice ships the in-process default-pinning tests. 327 unit tests pass (was 325; +2).

The NO WAIT("") modifier wasn't implemented at all. This slice closes both gaps. PerMigration tracking + flush: - StatementDispatcher gains a HashSet _dirtyIndices field that accumulates mutated index names across statements. Under PerMigration the per-statement implicit wait records the index and returns immediately; the resource runner calls dispatcher.FlushImplicitWaitsAsync at end of resource pass for a single consolidated _cluster/health call across all dirty indices. PerStatement and Off paths are unchanged. - Both up (RunStatementsFromJsonAsync) and down (RollbackStatementsFromJsonAsync) call FlushImplicitWaitsAsync at the end. Down is symmetric because rollback statements (CREATE / DROP / REINDEX / ALIAS SWAP) are themselves mutating. - Sequential dispatch within a resource runner means HashSet without locking is correct. NO WAIT("") modifier: - Grammar — new `noWaitWithJustification` parser fragment shared alongside the existing UNSAFE one (both reuse `quotedString` which rejects empty/whitespace-only). Wired into all five mutating verbs per R-12: CREATE INDEX, REINDEX, ALIAS SWAP, UPDATE SETTINGS, APPLY POLICY. Modifier is the trailing clause so it never conflicts with WITH BODY / VIA ALIAS / etc. - AST — five mutating records gain an optional NoWaitJustification string field. Records use parameterless defaults so existing call sites in tests (and the MIGRATE INDEX expansion grammar) continue to compile without changes. - Dispatcher — ImplicitWaitIfMutatingAsync now takes (verb, justification) and emits a structured WARN log under PerStatement when a justification is present (the `migration.no_wait{reason, idx, verb}` spec event). Under PerMigration the per-statement wait is already a no-op until the end-of-migration flush, so NO WAIT degrades to a DEBUG-level acknowledgement on that path. - ApplyPolicy now also participates in the implicit wait per R-12's enumeration; previously the dispatcher omitted it. Tests: - 7 new NoWaitParserTests covering the modifier shape on each of the five mutating verbs plus a stacking test (REINDEX UNSAFE + NO WAIT together — they're independent opt-outs of different safe-defaults and capture cleanly into separate AST fields). - 4 spec'd parse-time-rejection tests (bare NO WAIT, empty justification, whitespace-only, DROP-INDEX-doesn't-accept) are blocked on a wider parser-hygiene issue (Parlot's TryParse doesn't anchor to EOF; trailing tokens after a successful prefix-match are silently dropped). Tracked as a known limitation in a code comment; fixing it requires `.Eof()` on the top-level OneOf which affects every verb's accept criteria — separate hardening slice. - 334 unit tests pass (was 327; +7).

The resolver accepts any relative path under the migration's resource folder — `@foo.json`, `@bodies/foo.json`, `@configs/v2/foo.json` are all equally valid. Imposing a folder convention via the samples implies a constraint that doesn't exist. Sample 4 (single body) flattened: hot-warm-cold-policy.json now lives at the migration root and the statement reads `CREATE POLICY ... WITH BODY @hot-warm-cold-policy.json`. Demonstrates that the simplest path works without ceremony. Sample 3 (multiple bodies) keeps `bodies/` because grouping is the legitimate case for a subfolder when a single migration has more than one body file. Provider README's "Form 1" example updated to use a flat path (`@users-mapping.json`) and a new sentence makes the policy explicit: "Subfolders are optional. ... Group bodies into subfolders when a single migration has many of them; otherwise leave them flat at the migration root." The `bodies` keyword in the JSON wrapper stays — keyword/section name mirror is the cognitive payoff of the design (author writes `WITH BODY $foo` and looks up `bodies.foo`); replacing it with `data` or `content` would decouple the vocabulary for negligible benefit. No grammar changes. Samples csproj's EmbeddedResource path updated to match the flattened layout.

From 8dcf44d1d28017f42017b698492a42fd722d31a3 Mon Sep 17 00:00:00 2001 From: Brenton Farmer Date: Sun, 3 May 2026 13:16:34 -0700 Subject: [PATCH 37/51] Test: Phase 2 Slice 2.12 - R-24c gap-fill (production scenarios c/d/g/i/k/m) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the R-24c production-scenario suite gaps that earlier slices hadn't covered. R-24c is the "production-capable" gate per the requirements doc; six scenarios remained: (c) Mapping update on existing index produces "no reindex" gotcha diagnostic (d) Static settings update fails clearly without CLOSE, succeeds with it (g) dynamic:strict rejects unmapped fields with the documented error (i) Reindex op_type:create skips partial-prior-run docs (no double- write after a crashed prior run) (k) Lock primary-shard contention on multi-node — N concurrent acquires, one winner, bounded tail latency under PA-2 replicas:0 (m) Ledger refresh budget at scale — 100 writes complete within budget on multi-node (a)/(b)/(h)/(j)/(n)/(o) covered by earlier slices; (e) defers to plan task 2.1 (Tasks API); (f) defers (toxiproxy infrastructure); (l) REMOVED per ADR-0016. R-24c (c) — UPDATE MAPPING diagnostic Adds an INFO-level log to DispatchUpdateMappingAsync naming the "mapping changes don't reindex existing data" gotcha and pointing at MIGRATE INDEX (R-30) as the canonical propagation pattern. The diagnostic surfaces the silent-wrong-state class without blocking the operation; the test pins its presence so a refactor that drops the log fails the gate. Tests: OpenSearchR24cGapFillIntegrationTests — 5 single-node scenarios (c, d once for the failure path + once for the CLOSE-succeeds path, g, i), all single-node Testcontainers. OpenSearchR24cMultiNodeIntegrationTests — 2 multi-node scenarios (k concurrent-lock-acquire with bounded tail-latency assertion, m 100-migration ledger-write budget at 60s). [TestCategory("MultiNode")] so the existing multi_node_tests.yml CI workflow picks them up alongside the 4 keystone tests from Slice 2.11. All tests use [TestCategory("R-24c")] so the production-capable suite can be filtered and reported as a unit. Integration tests stay gated behind the EnableIntegrationTests MSBuild property; CI activates them on PRs. Build clean across all targets. 334 unit tests still pass (no unit- test changes in this slice; all R-24c work is integration-tier). --- .../Internal/Dispatch/StatementDispatcher.cs | 22 +- .../OpenSearchR24cGapFillIntegrationTests.cs | 546 ++++++++++++++++++ 2 files changed, 567 insertions(+), 1 deletion(-) create mode 100644 tests/Hyperbee.Migrations.Integration.Tests/OpenSearchR24cGapFillIntegrationTests.cs diff --git a/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Dispatch/StatementDispatcher.cs b/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Dispatch/StatementDispatcher.cs index b4065ce..aa0497e 100644 --- a/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Dispatch/StatementDispatcher.cs +++ b/src/Hyperbee.Migrations.Providers.OpenSearch/Internal/Dispatch/StatementDispatcher.cs @@ -352,7 +352,27 @@ private static async Task DispatchUpdateMappingAsync( UpdateMap var response = await ll.Indices.PutMappingAsync( ast.IndexName, PostData.String( body ), ctx: context.CancellationToken ).ConfigureAwait( false ); - return BuildResult( verb, response, $"mapping updated on `{ast.IndexName}`" ); + var result = BuildResult( verb, response, $"mapping updated on `{ast.IndexName}`" ); + + // R-24c (c) — the "no reindex" gotcha.

Pass criterion: AwsSigV4NotConfiguredException at startup with the exact AddOpenSearchAwsClient remediation snippet. (2) Smoke test — runs all 8 samples against the AWS domain; verifies ledger forensic fields (R-06) populated correctly, including appliedBy for credential-identity confirmation. (3) ISM endpoint detection — examines bootstrapper's log for the ism-detect resolution line. Documents the exact remediation (IAM action) when neither prefix probe succeeds. (4) Credential rotation (optional, long-running) — exercises R-21 #4 per-request credential resolution by running >1 hour with IRSA / instance-profile credentials. - Reporting protocol: every release MUST add either a PASS or DEFERRED line to the release checklist. Silent skipping is forbidden by the process. - Failure-mode triage section pointing each step's failure at the likely cause and the code path to investigate. - Out-of-scope explicitly: full CI automation of the runbook (v1.1 per requirements doc Open Questions); ISM step against OpenSearch Serverless (Serverless doesn't expose ISM); cross-region failover. docs/runbooks/INDEX.md: - New top-level index for the runbooks subtree, matching the docs/ convention used elsewhere (decisions/INDEX.md, etc.). --- docs/runbooks/INDEX.md | 5 + docs/runbooks/opensearch-aws-validation.md | 165 +++++++++++++++++++++ 2 files changed, 170 insertions(+) create mode 100644 docs/runbooks/INDEX.md create mode 100644 docs/runbooks/opensearch-aws-validation.md diff --git a/docs/runbooks/INDEX.md b/docs/runbooks/INDEX.md new file mode 100644 index 0000000..ecf7e22 --- /dev/null +++ b/docs/runbooks/INDEX.md @@ -0,0 +1,5 @@ +# runbooks/INDEX.md + +| File | Purpose | Cadence | +|------|---------|---------| +| [opensearch-aws-validation.md](opensearch-aws-validation.md) | Manual / scheduled validation of AWS-specific behaviors (SigV4, endpoint loud-fail, ISM capability detection, credential rotation) for the OpenSearch provider. | Pre-release; nightly when AWS credentials available. | diff --git a/docs/runbooks/opensearch-aws-validation.md b/docs/runbooks/opensearch-aws-validation.md new file mode 100644 index 0000000..b192850 --- /dev/null +++ b/docs/runbooks/opensearch-aws-validation.md @@ -0,0 +1,165 @@ +# AWS Managed OpenSearch — Scheduled Validation Runbook + +**Status:** Draft v1 +**Owner:** Hyperbee Migrations maintainers +**Cadence:** pre-release; nightly when AWS credentials are available in CI +**Per:** R-28c (scheduled validation), R-21 (auth), R-24c (production scenarios) + +## Purpose + +Single-node Testcontainers (every PR) and 3-node multi-node Testcontainers (every PR via [`multi_node_tests.yml`](../../.github/workflows/multi_node_tests.yml)) cover the in-cluster correctness behaviors.

R-27 explicitly calls for the template-propagation FAQ "featured prominently in the README as the answer to 'how do I apply template changes to existing data?'"; this slice delivers it.

New mapping applies; documents that don't fit the new mapping fail explicitly (rather than silently mis-typing). +3. **ALIAS SWAP users-current FROM users-v1 TO users-v2** - one atomic _aliases body containing both the remove-from-v1 and add-to-v2 actions.

Use this if your application doesn't read through an alias, or if you intend to retain both indices for read-traffic comparison before cutover. + +### When the source has active writes during the migration + +The standard reindex captures only documents present at the time it starts. Writes against v1 during the reindex do NOT make it into v2 automatically. For write-during-migration scenarios, two patterns: + +- **Dual write**: application writes to both v1 and v2 during the migration window, then reads switch over. +- **Post-swap delta reindex**: rerun the reindex from a saved checkpoint after the swap to catch v1 writes that arrived during the window. + +The composite verb explicitly does NOT solve the dual-write problem - that's an application concern, not a migration tool concern. + +## Why not just UPDATE MAPPING? + +You can use UPDATE MAPPING to add fields to an existing index. New documents will have the new fields available; queries that filter on the new field will work for those new documents. + +You CANNOT use UPDATE MAPPING to: + +- Change the type of an existing field (string -> integer, keyword -> text, etc.) +- Remove a field +- Change an analyzer's output for existing documents +- Apply a new dynamic-mapping policy to historic data + +Those changes require a reindex.

The ALIAS SWAP precondition is in-body so there's no TOCTOU window. +- **Atomicity is explicit.** The sub-statements run as a halting sequence; failure of any sub-statement halts the rest and feeds R-19 partial-rollback ledger semantics. +- **The intent is readable.** "MIGRATE INDEX users-v1 TO users-v2" reads as the operation it is. Three separate statements bury the intent across multiple lines. +- **Template resolution is offline-pure.** The parser carries the template name unresolved; the runtime fetches the live template body just before CREATE INDEX dispatch (ADR-0015).

See the [provider package README](https://github.com/Stillpoint-Software/Hyperbee.Migrations/blob/main/src/Hyperbee.Migrations.Providers.OpenSearch/README.md) for the full per-verb reference. + +Bodies attach to a statement via `WITH BODY `. Three forms (ADR-0017): `@path/to/file.json` for direct file references, `$name` resolved against an inline `bodies` section, or for back-compat the original sibling-property pattern. + +## MIGRATE INDEX (the canonical mapping-propagation pattern) + +OpenSearch is unusual: mapping changes do NOT propagate to existing documents. UPDATE MAPPING applies to documents written AFTER the update, not before. To apply a mapping change to existing data, the canonical pattern is: + +1. Create a new versioned index with the new mapping. +2. Reindex from the old index to the new (with `op_type: create` so retries are safe). +3. Atomically swap an alias from the old index to the new. + +The `MIGRATE INDEX` composite verb encodes that pattern as one line: + +``` +MIGRATE INDEX users-v1 TO users-v2 WITH TEMPLATE users-template VIA ALIAS users-current +``` + +The composite expands at parse time to CREATE + REINDEX + ALIAS SWAP, with the template body fetched from the live cluster at dispatch time. Author owns naming explicitly; the migration tool stays unopinionated about index versioning conventions. + +If your team is hitting "I changed the mapping but the existing data isn't seeing it", `MIGRATE INDEX` is the answer. + +## Locking + +The provider uses a single OpenSearch document on `LockIndex` for distributed locking. Acquisition is `op_type=create` (atomic claim); on conflict, a realtime GET checks staleness before any takeover. The renewal loop refreshes the heartbeat at `LockRenewInterval`; CAS conflicts on renewal signal that another runner has taken over and the in-flight migration is canceled cleanly. `LockMaxLifetime` caps total wall-clock hold so a hung migration cannot lock forever. + +The lock index uses `number_of_replicas: 0` (PA-2) so concurrent acquire under N runners doesn't stall on replica-write coupling. + +## Ledger forensics + +The migration ledger captures forensic fields per R-06 so post-mortems have what they need without log spelunking: + +| Field | Purpose | +|-------|---------| +| id | Record id (version-name) | +| runOn | Apply timestamp | +| direction | Up / Down | +| status | succeeded / failed / partially_rolled_back | +| appliedBy | {machineName}/{processId} | +| error | Failure detail, when applicable | +| failedStatementIndex | R-19: which rollback statement halted the Down sequence | + +R-19 partial-rollback semantics: when a Down sequence halts partway, the ledger entry is overwritten to `partially_rolled_back` and subsequent runs in either direction are refused unless `ForceResume = true`.

They are areas where the verification could be tighter: + +1. **ADR-0012 (WithProductionDefaults)** — the extension method exists and registers a marker, but the options-factory wiring that flips the four defaults (Green threshold, PerMigration waits, RequireExplicit context, RequireUnsafeJustification) on options-instance construction is a Phase 6 follow-up per the ADR's own consequences section. Today, calling `WithProductionDefaults()` is the marker registration; the user still has to set the four options manually. Worth a follow-up slice once the options-factory pattern is settled. Not a regression — the slice was scoped this way intentionally per the requirements doc. + +2. **ADR-0009 (Convention-Based Record IDs)** — verified indirectly through ledger-bearing tests rather than a dedicated unit test. The convention is simple enough (version + type name) that the indirect coverage is sufficient, but a focused convention-output test would tighten the regression net for any future ID-format change. + +3. **ADR-0016 (No File-Level Templating)** — verified through absence (no Hyperbee.Templating reference in the project file). A code-level "no positive test for absence" is correct but means a future contributor adding the dependency wouldn't be alerted by CI. The provider's csproj is small enough that a dependency-scan grep in the build is the cheapest possible safeguard if future drift becomes a concern. + +### Open Questions during the audit + +None.

close ADR-0009 + ADR-0016 audit soft spots Three hardening items from the ADR compliance audit follow-ups: 1. EOF-anchor the OpenSearch statement parser Apply .Eof() to the top-level Parlot parser so trailing tokens after a successful prefix-match are reported as parse errors rather than silently dropped. Restores the four NO WAIT parse-time-rejection tests previously deferred: - bare NO WAIT (no parens, no justification) - NO WAIT("") with empty justification - NO WAIT(" ") with whitespace-only justification - DROP INDEX ... NO WAIT (NO WAIT not permitted on non-mutating verbs) Wraps grammar-level InvalidOperationException (from quotedString non-empty validation, ParseVersionLiteral, etc.) into OpenSearchParseException so callers handle one exception type. 2. ADR-0009 focused convention test New DefaultMigrationConventionsTests asserts the documented record-id format (record..), tightening the regression net beyond indirect ledger-bearing test coverage. 3. ADR-0016 dependency-scan test New OpenSearchProviderDependencyTests asserts the OpenSearch provider assembly does not reference Hyperbee.Templating. If a future contributor adds the package, CI fails before merge. Verification: 343 unit tests pass on net8/9/10 (1,029 executions, 0 failures).
