From bd52b4d5ad36c3ea336d28066522fb6f02fcb3ce Mon Sep 17 00:00:00 2001 From: Patrick Lee Scott Date: Fri, 4 Sep 2026 22:48:45 -0500 Subject: [PATCH 01/69] feat!: fence aggregate snapshot projections by source version Add explicit aggregate_snapshot projection authoring, atomic source fences in memory/SQLite/PostgreSQL, tombstone-aware late confirmation, and adapter regression proofs. BREAKING CHANGE: ProjectionRecordMetadata gains source_snapshot. Existing unversioned read-model rows require an explicit rebuild before opting into source-snapshot semantics. Apply framework migration 0005 before using SQL-backed stores. --- README.md | 58 ++ migrations/inventory.json | 12 + .../0005_projection_source_snapshots.sql | 3 + .../0005_projection_source_snapshots.sql | 3 + src/command_ledger/tests.rs | 1 + src/graphql/protocol/tests.rs | 1 + .../projection_protocol/direct_projection.rs | 5 + .../projection_protocol/state_impl.rs | 26 +- .../projection_protocol/store_impl.rs | 6 + src/lib.rs | 16 +- src/projection/executor.rs | 97 +++- src/projection/mod.rs | 3 + src/projection/placement.rs | 6 + src/projection/plan.rs | 8 + src/projection/program.rs | 32 ++ src/projection/source_snapshot_tests.rs | 503 ++++++++++++++++++ src/projection_protocol.rs | 6 +- src/projection_protocol/source_snapshot.rs | 99 ++++ src/projection_protocol/store/commit.rs | 8 + src/projection_protocol/store/identity.rs | 19 +- src/projection_protocol/store/query.rs | 2 + src/projection_protocol/store/replay.rs | 1 + src/projection_protocol/store/tests.rs | 1 + src/projection_protocol/workspace.rs | 33 +- src/sqlx_repo/projection_protocol/reads.rs | 38 +- .../projection_protocol/store_impl.rs | 8 +- src/sqlx_repo/projection_protocol/writes.rs | 58 +- src/sqlx_repo/repo/backend.rs | 18 +- tests/fixtures/source_snapshot_delete.graphql | 3 + tests/fixtures/source_snapshot_save.graphql | 3 + 30 files changed, 1020 insertions(+), 57 deletions(-) create mode 100644 migrations/postgres/0005_projection_source_snapshots.sql create mode 100644 migrations/sqlite/0005_projection_source_snapshots.sql create mode 100644 src/projection/source_snapshot_tests.rs create mode 100644 src/projection_protocol/source_snapshot.rs create mode 100644 tests/fixtures/source_snapshot_delete.graphql create mode 100644 tests/fixtures/source_snapshot_save.graphql diff --git a/README.md b/README.md index 1a8b209ea..b75315d00 100644 --- a/README.md +++ b/README.md @@ -267,6 +267,64 @@ mutation SaveTodo { } ``` +#### Full-state projections and out-of-order events + +Broker delivery order is not necessarily aggregate commit order.

A late snapshot +cannot overwrite a newer row or resurrect a deleted one. Even deletion before +creation leaves a durable tombstone. A newer snapshot can recreate the row. +Source fences, physical rows, row revisions, broker checkpoints and causal +observations commit atomically in the memory, SQLite and PostgreSQL adapters. +A stale input confirms the current row revision without generating a fake row +update; a concurrent change makes that confirmation retry through the normal +projection conflict path. + +Use this only for complete replacement snapshots with stable row keys. Every +affected key must be owned by one aggregate stream; joins, counters, partial +patches and relationship side effects need their own ordering/fold semantics. +This mode rejects delta operations, expression partitions and direct placement. +Different aggregate streams cannot take over an existing fenced key. Matching +source versions with conflicting occurrence content fail closed. + +Migration `0005_projection_source_snapshots` persists the fence alongside each +record, including tombstones; compaction does not remove it. Enabling this on +an existing unversioned projection requires an explicit read-model rebuild +from retained canonical events. Merely changing the projection version or epoch +does not infer a source version for existing rows. The normal ordered-delivery +contract and transport identity checks still apply; this is not a replacement +for reliable broker delivery or an incremental-event reorder buffer. + +Custom program factories can use `ProjectionProgram::with_source_snapshots()`; +the policy is part of the canonical program identity. Browser optimism continues +to use the same mutation program, and authoritative confirmation uses committed +row revisions rather than comparing browser timestamps. + Handlers stay thin: most Todo commands are `portable_command!` — shard, invoke one domain method, commit Eventual. `todo.create` keeps a `handle:` escape hatch when the body needs extra checks. diff --git a/migrations/inventory.json b/migrations/inventory.json index 1580c1173..f241a8742 100644 --- a/migrations/inventory.json +++ b/migrations/inventory.json @@ -48,6 +48,18 @@ "path": "migrations/postgres/0004_command_ledger_atomic_state.sql", "sha256": "bc49ca9c58a294b7c5876c9fcde8a14a8b6110594a06c48b37720d320a22d97e" } + }, + { + "version": 5, + "description": "projection source snapshots", + "sqlite": { + "path": "migrations/sqlite/0005_projection_source_snapshots.sql", + "sha256": "2cb605be4ec190d9b3f156bdbbeb83a76e5f1f37287a8a7f3c2653dafbede442" + }, + "postgres": { + "path": "migrations/postgres/0005_projection_source_snapshots.sql", + "sha256": "2cb605be4ec190d9b3f156bdbbeb83a76e5f1f37287a8a7f3c2653dafbede442" + } } ] } diff --git a/migrations/postgres/0005_projection_source_snapshots.sql b/migrations/postgres/0005_projection_source_snapshots.sql new file mode 100644 index 000000000..2d7f5b4a1 --- /dev/null +++ b/migrations/postgres/0005_projection_source_snapshots.sql @@ -0,0 +1,3 @@ +-- Fences survive deletion, process restart and change-log compaction. +-- NULL denotes a delivery-ordered (not source-snapshot) projection. +ALTER TABLE projection_records ADD COLUMN source_snapshot TEXT;

Return them from CellDispatchResult and stop the Worker response path scanning retained outbox messages. BREAKING CHANGE: successful cell command replay payloads now contain the result and projection inputs. Old stored successful receipts require explicit handling; no legacy replay fallback is provided. The public HTTP envelope is unchanged. Regression: restart with events and receipts but no outbox history; replay the same result and nonempty evidence without new events or publication. All 787 SQLite-feature library tests pass; celld Worker wasm check passes. Physical outbox deletion and SQL cell activation remain pending. --- src/microsvc/cell_host/causal.rs | 42 ++++++++++--- src/microsvc/cell_host/tests.rs | 100 ++++++++++++++++++++++++++++++- src/microsvc/cell_host/wire.rs | 6 +- src/microsvc/service/routes.rs | 15 ++++- tests/celld/README.md | 13 ++++ tests/celld/worker/src/lib.rs | 26 ++------ 6 files changed, 170 insertions(+), 32 deletions(-) diff --git a/src/microsvc/cell_host/causal.rs b/src/microsvc/cell_host/causal.rs index a27a3ecd4..df11ae6f7 100644 --- a/src/microsvc/cell_host/causal.rs +++ b/src/microsvc/cell_host/causal.rs @@ -7,8 +7,20 @@ use std::time::Duration; +use serde::{Deserialize, Serialize}; use serde_json::Value; +use super::CellProjectionEventWireItem; + +/// Bounded retry material, owned by the command ledger and expired with its +/// replay retention.

With GraphQL, +`ReadRouting::new(replica).stale_tolerant(document, operation_name)` explicitly +registers stale-tolerant reads. Pass it to `GraphqlEngineBuilder::read_routing`; +the builder's original repository remains the authoritative primary. Schema and +SQL dialect must match. Unregistered queries, command recovery and live refreshes +use primary. SQLx pools do not certify replay progress. + +Generated query artifacts carry the protocol fingerprint. The client sends +`extensions.gatewayFreshness`, bound to its server-established schema, protocol, +policy and cache scope. Generated command dependencies select affected queries; +unknown effects broaden within the authorized surface. Pending effects force +primary without confirming projection. Confirmed query/live index clocks and +Atomic record fences survive optimistic layer retirement. An origin response +that cannot cover supplied minima returns `FRESHNESS_PENDING`, including +incomparable scopes. No stale fallback occurs on primary failure. Context limits +fail explicitly rather than discarding retained evidence.

An unselected capability allocates no cache. + +On the origin, after framework and application migrations, install +`GatewayVersionStore::install(&pool, application_namespace, physical_tables)` +and pass the resulting store to `GraphqlEngine::builder(...).gateway_versions(store)`. +The inventory must cover every table touched by an eligible compiled query, +including relationship targets and intermediate join tables. Installed projection +proof tables are included automatically because even a no-op projection can +change the response's evidence. This is conservative across projection partitions. + +Each consumer sends an authenticated validation request to the configured origin +using the existing GraphQL endpoint with the reserved `gatewayDelivery` extension. +Origin authentication, schema validation and the compiler's row/field authorization +run for every request. Validation executes a single dependency-vector SQL statement +inside a primary read snapshot; it executes no result SQL. The gateway accepts the +identity and opaque validator only from that origin response. Public request metadata +cannot grant cache scope. The existing executor still owns commands and command status. + +A miss executes the query with its data, causal metadata and validator in the same +SQL snapshot. The gateway revalidates after the fill and installs only if its own +validator is still current. Every hit revalidates on the primary, so delayed or lost +invalidation notifications cannot certify old private data. Authentication/primary +failure never falls back to cached private data. Missing dependency hooks make the +operation bypass reuse; unknown/custom resolver dependencies, commands/status, +errors, partial results, cookie-setting responses, `no-store`, and `Vary: *` also +bypass storage. Required client freshness minima must be covered by the stored proof. + +Defaults are 1,024 entries, 16 MiB total response bytes and 1 MiB per response. +Oversized/streaming responses continue to the consumer without truncation or storage. +Native response-header/read deadlines bound validation and capture. Entries use LRU +eviction; `invalidate_all()` also fences fills that began before the reset. +`GatewayVersionStore::metrics()` reports origin validations separately from actual +result SQL executions; these counters do not contain subjects or query text. + +For explicitly public content, `store.public_snapshot(exact_document, operation_name, +max_age_seconds)` permits 1–86,400 seconds of content age. This applies to all variable +values of that exact operation. It still requires fresh origin admission and preserves +subject isolation. Age starts at the original origin validation and is never extended +by copying an entry, a new admission, or another cache layer. The default policy always +requires the current version vector. + +## Activation and rollback + +Migration `0006_gateway_dependency_versions` is additive and registered in the normal +SQLite/PostgreSQL migration inventory. No application data is backfilled or rewritten. +Activation installs transactional write hooks and starts a new random epoch. Normal +SQL producers, Eventual projectors, Atomic projection commits, deletes, and PostgreSQL +TRUNCATE all update versions in their data transaction. A failed transaction rolls +versions back with the data. Privileged writers that disable/drop hooks are unsupported +until coverage is restored; validation detects missing/disabled hooks and bypasses reuse. +Applications must not manually replace framework hooks with different implementations. + +Install after application migrations, before enabling cache bindings. Rebuild or change +writer coverage in a controlled migration window, reinstall hooks/start a new epoch, +then invalidate gateway stores before reopening traffic. `rotate_epoch` is available +for an explicit rebuild boundary. Epochs are random identities, not inferred wall clocks +or PostgreSQL WAL positions. Disable the cache binding on rollback; leave additive +metadata in place until a separately planned cleanup. Never apply cleanup to a live DB +as part of a gateway cache rollback. diff --git a/migrations/inventory.json b/migrations/inventory.json index f241a8742..ccea03955 100644 --- a/migrations/inventory.json +++ b/migrations/inventory.json @@ -60,6 +60,18 @@ "path": "migrations/postgres/0005_projection_source_snapshots.sql", "sha256": "2cb605be4ec190d9b3f156bdbbeb83a76e5f1f37287a8a7f3c2653dafbede442" } + }, + { + "version": 6, + "description": "gateway dependency versions", + "sqlite": { + "path": "migrations/sqlite/0006_gateway_dependency_versions.sql", + "sha256": "c156bc51dddecd49b1beef7bb4069557b024c19cb1271f0ec9cc0efe71939471" + }, + "postgres": { + "path": "migrations/postgres/0006_gateway_dependency_versions.sql", + "sha256": "c156bc51dddecd49b1beef7bb4069557b024c19cb1271f0ec9cc0efe71939471" + } } ] } diff --git a/migrations/postgres/0006_gateway_dependency_versions.sql b/migrations/postgres/0006_gateway_dependency_versions.sql new file mode 100644 index 000000000..287d427cc --- /dev/null +++ b/migrations/postgres/0006_gateway_dependency_versions.sql @@ -0,0 +1,9 @@ +-- Private gateway dependency versions.

This creates no snapshot cache. To select both, use +`NativeDelivery::new(NativeDeliveryOptions { snapshots: Some(...), coalescing: +Some(...) })`. All capabilities remain explicit and independently removable. +The origin uses the authenticated delivery control path and version store +described in [snapshot-cache.md](snapshot-cache.md). + +Every consumer authenticates and validates at the origin before joining. A group +key binds the exact origin subject/scope, operation/variables/extensions, current +dependency validator, and exact freshness requirements. Different or stronger +floors conservatively form different groups; no minimum is weakened to improve +sharing. Mutations, status operations and unknown origin eligibility never join. +The result retains its own complete data and protocol envelope. In-flight sharing +can serve an otherwise successful admitted query that lacks future cache eligibility; +any required minima must still be proven by that response. + +An operation owns one shared future. The registry retains a weak reference, and +each consumer holds a cancellation lease. Dropping one lease leaves the other +consumers' work running. Dropping the last lease immediately drops the upstream +future; no detached task remains as a hidden owner. Each response waits for its +consumer's own credential expiry deadline, and expiry is checked again before +delivery. The origin is also revalidated after result execution to detect a +changed scope/policy. A completed group is removed when its consumers finish; +with the cache disabled, a later nonoverlapping query executes normally. + +Default limits are 256 active groups, 1,024 consumers per group, a 30-second +operation deadline, and 1 MiB of complete response bytes per group. Native ingress +capacity also bounds all active requests. A full registry rejects additional +joins without evicting work needed by existing consumers. Expired generation +identities cannot release a newer same-key group. Oversized streams, errors, +cookie-setting and otherwise nonshareable responses go to one consumer; other +consumers execute normally with their own admission and freshness. They are never +stored as successful shared snapshots. + +`NativeDelivery::flight_counts()` exposes active groups/consumers without +identifiers. Origin metrics distinguish result SQL from per-consumer validation. +Portable `FlightKey`, `FlightLimits` and `FlightRegistry` provide the same bounded +identity, generation and refcount contracts for runtime adapters.

The origin needs the authenticated delivery control +path and version coverage described in [snapshot-cache.md](snapshot-cache.md). +Custom embedded executor routers conservatively keep independent subscriptions; +the canonical engine and eligible remote whole-operation executors support sharing. + +Every consumer is admitted by the origin, including credentials supplied through +GraphQL `connection_init`. The gateway passes these credentials to the backend's +existing validator; it does not derive a subject from cookies or unverified JWTs. +A remote client initially uses a temporary origin WebSocket for the real connection +acknowledgement. It owns no subscription and closes before operation coordination. +Thus 100 clients incur 100 admissions and handshake costs but can share one steady +upstream subscription and producer. HTTP control requests do not execute result SQL. + +Groups bind the exact document, variables, origin subject/cache scope, policy, +schema and protocol. Each consumer keeps its own transport ID, expiry, queue and +freshness requirements. Different resume cursors start independent replay. Handoff +requires the same operation plus an exact supported, comparable cursor vector and +matching data; the consumer's replay frames remain queued before future shared +frames. Unknown cursors keep independent streams. Equal data alone never proves +cursor equality. Duplicate suppression hashes the whole data and protocol envelope, +so new confirmation evidence is delivered even when values are unchanged. + +Defaults bound a coordinator to 256 groups, 1,024 consumers per group, 16 pending +frames per consumer, 1 MiB per full frame, eight retained history frames and a +one-hour group lifetime. Native ingress bounds socket/request counts and wire +message sizes as well. Frames share immutable storage across consumer queues. +If a slow consumer cannot preserve all evidence within its queue, it receives +`LIVE_RESET_REQUIRED`; a blocked socket is closed so it must reconnect. No +latest-value replacement silently discards confirmation proof. Group deadline, +upstream loss and incomplete/invalid origin envelopes also require recovery. + +Dropping a consumer releases only its lease. Last leave aborts the actual upstream +stream, socket and origin change-feed receiver, including a pending origin SQL +read. An expired credential cannot continue receiving shared frames or own other +consumers' upstream: the remaining valid consumer reconnects with its own origin +credential and the last proven resume cursor. Normal GraphQL completion drains +queued frames; unexpected transport loss requires reset. Reconnect authenticates +again. Shared outbound sockets do not hibernate for free. + +`NativeDelivery::live_counts()` reports active groups, consumers, cumulative source +attempts, resets, upstream frames, exact duplicate frames and safe handoffs. Source +attempts include credential reconnects; they are not a count of active producers. +`GraphqlEngine::live_subscriber_count()` separately reports actual origin producer +subscriptions. No credentials or subject identifiers appear in these counters. + +Disable `live_sharing` and remove the live delivery resource to restore independent +subscriptions. Existing client resume/reset and response-sealing behavior remains +in force. No migration or new credential is required by live coordination itself. diff --git a/docs/gateway/query-coalescing.md b/docs/gateway/query-coalescing.md index 89138c5a4..a120f4299 100644 --- a/docs/gateway/query-coalescing.md +++ b/docs/gateway/query-coalescing.md @@ -3,7 +3,7 @@ Mount `NativeDelivery::coalescing(FlightLimits)` with the GraphQL binding's `coalescing` capability.

Object delivery + +Enable `gateway-worker` to use `distributed::gateway::worker`. It compiles to +`wasm32-unknown-unknown` with workers-rs and the portable gateway/delivery +contracts. It links no Axum, Tokio runtime, SQLx, GraphQL server or domain bus. +workers-rs includes Tokio with no features for utility types. Commands +continue to execute at the configured backend; the Worker is ingress. + +An application constructs `WorkerGateway` with its portable `GatewayConfig`, +explicit `WorkerBinding` resources, `WorkerOptions` and `WorkerAuth`. Mount +`gateway.fetch(request, env)` from the Worker fetch entrypoint. Bind handlers, +an asset service, UI/auth reverse proxies, or a whole remote GraphQL endpoint. +Routes use the same exact/longest-segment ownership as native ingress. A selected +handler's error is terminal. The public origin is configured, never taken from +incoming forwarding headers. The adapter retains Origin and duplicate cookies, +rewrites private-origin redirects and rejects proxy loops. Fetch requires Host +to match the fetched URL; trusted public authority reaches delegated handlers +through configured origin and forwarded headers. + +`WorkerAuth::new` accepts an application-owned asynchronous session/provider +implementation returning the shared `RequestContext`. It must validate the +credential before constructing identity or a backend bearer credential. +`WorkerAuth::anonymous()` accepts opaque UI/auth cookies but rejects HTTP bearer +input. It does not turn a cookie or decoded JWT into identity. Auth.js remains +the session/callback/refresh/logout owner when delegated; no second identity +store is introduced. GraphQL connection_init credentials are forwarded to and +validated by the backend. WebSocket commands/status stay on that backend socket +identity path. HTTP query reuse for a WebSocket operation requires explicit +origin control-protocol recognition; older/custom origins remain independent. + +## Optional coordination + +A `WorkerDeliveryBinding` declares namespace, epoch, shard count and independent +snapshot/coalescing/live resources. With `delivery: None`, forwarding creates no +coordinator. It also works with a backend that has no delivery control protocol. +Declare a workers-rs Durable Object in application code and construct one +`Rc` in its `new`. Route its fetch method through +`gateway.fetch_coordinated(request, env, coordinator)`. This is an in-process +mount; public headers cannot assert that admission already happened. + +All ingress instances must use the same namespace, binding name, epoch and shard +count. Operation documents, selected operation and canonical variables select a +shard. This routing hash conveys no authorization. The DO repeats provider +admission and obtains a fresh origin validation for **every** consumer before +reuse. The actual cache/flight/live keys retain origin-resolved application, +endpoint, subject scope, schema/policy versions and freshness floors. Private +hits still cost origin validation; 100 eligible query consumers can share one +result SQL execution. WebSocket queries require a control capability check +before the HTTP reuse path and therefore have additional validation overhead. + +Use Worker-sized limits, for example the explicit limits in +[`tests/gateway-worker/src/lib.rs`](../../tests/gateway-worker/src/lib.rs). +Native defaults intentionally do not fit the Worker retained-payload budget. +The adapter rejects selected configurations exceeding 16 MiB of reserved cache, +flight and live payload. Live-frame charges follow actual shared ownership, +including consumer queues retained across handoff, and force explicit reset if +the budget is exhausted. This bounds wire payload, not the entire runtime heap: +parsed JSON, credentials, active requests, sockets and the application's own +allocations need additional memory headroom. Groups, consumers, frame sizes, +queue length, response sizes and operation lifetimes have independent limits. + +Modern GraphQL subscriptions use standard ping/pong payload echo as delivery +credits: the supplied JS transport echoes the payload. Full data and confirmation +proof stay unchanged. A client that does not acknowledge is reset instead of +silently accumulating data. Raw UI and legacy GraphQL sockets cannot assume that +protocol; they have bounded callback queues and cumulative delivery limits, +after which reconnect is required. `websocket_buffer_bytes` bounds a complete +frame and aggregate queued wire bytes per socket; arbitrary UI delivery is +limited to eight times this value per connection. Customize limits for the UI's +protocol. Outgoing origin sockets remain active and do not hibernate. One shared +steady-state producer does not mean one lifetime handshake: every consumer is +independently authenticated at the origin before grouping. + +## Recovery and cancellation + +Coordinator state is volatile. Restart starts empty and requires fresh origin +validation/replay. No invalidation feed is needed for correctness: validators +cover committed projection data and proof state, including external SQL writes. +An epoch or shard change abandons old cache/work; clients reconnect and present +origin-verifiable cursors. Cursor gaps, incompatible freshness and queue overflow +cause origin recovery or explicit reset. Last-leave drops the actual upstream +socket; one expired consumer cannot terminate another valid consumer's group. +The upstream can reconnect with a remaining consumer's current credential. + +Set the `enable_request_signal` compatibility flag. The adapter preserves +Request.signal through rebuilt requests, and cancellation drops the associated +Rust work and shared-flight ownership. Plain HTTP disconnects before headers +did not produce that signal in the pinned local workerd fixture; those requests +remain bounded by the configured deadline. Explicit ingress abort signals, +response-stream cancellation and live last-leave teardown have separate actual +runtime tests. A cancelled command is never retried by the gateway; cancellation +does not imply that backend effects were rolled back. + +The fixture's migration declares a new `DeliveryCoordinator` SQLite DO class; +the adapter stores no cache entries or identity grants in durable storage. For +local reset, stop the runner and change its epoch (or use fresh disposable local +state). Rollback disables delivery bindings while retaining independent remote +forwarding.

Lockfiles pin workers-rs 0.8.5, +Wrangler 4.129.0, Miniflare 5.20260903.0-alpha, workerd 1.20260903.1, and ws 8.21.3. + +The Rust tests start actual GraphQL engines and SQLite projection stores, then +launch Node clients against workerd. They count origin validations, actual +projection SQL, and actual live producers. Query tests cover 100 consumers, +current private hits, external SQL without an invalidation feed, restart, two +separate ingress Wasm isolates using one selected DO, and explicit ingress +AbortSignal cancellation. Live tests cover 100 real JWT-authenticated sockets, +subject isolation, projection commit fanout, proof-only updates, bounded slow +consumers, old-cursor handoff, retention gaps, expiry/reconnect, last-leave +teardown, two ingress isolates and coordinator restart. + +The proxy runner uses actual HTTP streams and text/binary WebSockets. The auth +runner reuses the production SvelteKit/Auth.js browser lifecycle fixture and +checks secure cookie attributes separately. Artifacts under `artifacts/` are +ignored. Fixture-only `/__coordinators`, origin control routes and distributor +cancellation headers are test instrumentation; the framework mounts none of +them. + +The multi-isolate runner uses Miniflare's explicit module manifest and v4-option +converter for its pinned v5 API. A direct workerd listening socket avoids making +the Node development proxy part of the gateway contract. Plain HTTP disconnects +before response headers did not trigger Request.signal in this local runtime; +the configured operation deadline remains the cleanup bound. The explicit +AbortSignal test proves propagation through service bindings into the DO, and +response-stream cancellation and WebSocket teardown are tested separately. diff --git a/tests/gateway-worker/check_dependencies.py b/tests/gateway-worker/check_dependencies.py new file mode 100644 index 000000000..f1109cc65 --- /dev/null +++ b/tests/gateway-worker/check_dependencies.py @@ -0,0 +1,17 @@ +#!/usr/bin/env python3 +"""The Worker gateway links portable control contracts, never a native server.""" +from pathlib import Path +import subprocess +manifest = Path(__file__).resolve().with_name("Cargo.toml") +output = subprocess.check_output(["cargo", "tree", "--manifest-path", str(manifest), "--locked", "--target", "wasm32-unknown-unknown", "--edges", "normal", "--prefix", "none"], text=True) +packages = {line.split()[0] for line in output.splitlines() if line.strip()} +forbidden = {"async-graphql", "async-graphql-axum", "sqlx", "sqlx-core", "axum", "reqwest", "tonic", "async-nats", "lapin", "rdkafka"} +assert not packages & forbidden, sorted(packages & forbidden) +assert "worker" in packages +# workers-rs itself uses Tokio's feature-free utility types.
