Verify the graph-node API schema snapshot in CI - #2854
Conversation
crates/subgraph/schema/raindex.graphql is the graph-node API schema cynic_codegen registers as truth in crates/subgraph/build.rs. Nothing in this repo produced it and nothing checked it. schema-snapshot deploys subgraph/ to a throwaway graph-node against a host anvil, introspects the endpoint, prints the SDL through lexicographicSortSchema, and diffs it against the committed file.

Full details: Linked Issues checkExplanation The changes provide the throwaway graph-node environment, schema deployment and introspection, deterministic GraphQL formatting, timeout-based retries, schema artifact upload, and snapshot comparison. The provided summaries do not verify the required repository-specific adaptation record or the demonstration that the check fails against a mutated snapshot. The excluded subgraph/package-lock.json also prevents verification of lockfile consistency for the pinned dependency. Resolution Provide reviewable evidence that the repository-specific adaptations were recorded and that the CI check was demonstrated to fail with a mutated snapshot. Inspect subgraph/package-lock.json, which was excluded by the path filters, to confirm it records the direct graphql@15.5.0 dependency consistently. Full details: Out of Scope Changes checkExplanation The workflow, schema-check script, Docker Compose services, schema introspection utility, GraphQL dependency, and generated-file ignore rule directly support the linked issue objectives. No unrelated code changes are identified. Full details: Docstring CoverageExplanation Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 2 functions across 2 files. (4 skipped: 4 unsupported.)

Run the required artifact regeneration before the drift check.
Add the rainix-copy-artifacts step sequence in nix develop github:rainlanguage/rainix#sol-shell before this assertion. Then check all generated artifacts, not only subgraph/, for uncommitted drift.
As per coding guidelines: “Regenerate artifacts — run the rainix-copy-artifacts step sequence ... Stage ALL changed artifacts or copy-artifacts drifts red.”

Wait for the IPFS API before graph-node deployment.
service_started does not confirm that IPFS accepts requests on port 5001. subgraph/check-api-schema.sh, Line 19, deploys through that API without a retry. Add an IPFS health check and require service_healthy so docker compose ... up --wait blocks until deployment can use IPFS.

Verbatim from the schema-snapshot artifact of run 33038854396. Substantively the committed file claimed `Clear` and `TakeOrder` implement only `TradeEvent` where schema.graphql declares `Event & TradeEvent`, and claimed `raindexs` on Query and Subscription where graph-node pluralises `Raindex` to `raindices`. The rest of the churn is canonical form: the snapshot kept graph-node's natural argument order, and printSchema renders argument lists and descriptions differently.

Closes #2852.
crates/subgraph/schema/raindex.graphqlis the graph-node API schema, andcynic_codegenincrates/subgraph/build.rsregisters it as truth for thegenerated client. Nothing in this repo produced it and nothing checked it, so a
wrong hand-edit compiled fine and only surfaced against a live endpoint at
runtime.
It cannot be regenerated offline the way
copy-artifactsregenerates the ABIs— reproducing it means running graph-node's own schema derivation. So this runs
graph-node.
The job
schema-snapshot, a second job inSubgraph unit tests:anvilfrom.#sol-shellon the runner host, reached by graph-node over thedocker host gateway. graph-node will not accept a deployment naming a chain
it has no adapter for.
subgraph/docker-compose.graph-node.yml, aSEPARATE compose file: rainix's
subgraph-testrunsdocker compose up --abort-on-container-exitoversubgraph/docker-compose.yml, so theseservices must not land in it.
subgraph/check-api-schema.shrunsnpm ci,graph build,graph create,graph deployinsubgraph/as committed.subgraph/print-api-schema.jsintrospects the deployed endpoint and printsthe SDL through
lexicographicSortSchema, so the snapshot does not encodegraph-node's internal type ordering. It retries: graph-node answers
Subgraph ... has not started syncing yetfor the first second or two aftera deploy.
diff -uagainst the committed snapshot, with the derived schema uploaded asan artifact so a mismatch is fixed by copying the artifact over the file.
The job asserts
git diff --exit-code -- subgraph/after, so build residue inthe source tree fails the job rather than being committed by accident.
What it found immediately
The committed snapshot was wrong. It is replaced here, verbatim from the job's
own artifact — 4534 lines to 3681.
Ignoring formatting, the difference is exactly four records — two interface
lists and two field names:
type Clear implements TradeEventandtype TakeOrder implements TradeEventwhere
subgraph/schema.graphqldeclares both asimplements Event & TradeEvent. The snapshot droppedEventfrom the interface list on both.raindexsonQueryand onSubscription, where graph-node pluralisesRaindextoraindices. Nothing in the repo queried that field, so itcompiled.
The rest of the churn is canonical form, not content: the 281 descriptions in
the file are identical as text between the two, and the old file kept
graph-node's natural argument order where
lexicographicSortSchemasortsarguments, hard-wrapped descriptions that
printSchemaemits on one line, andspread argument lists over multiple lines that
printSchemaprints inline.Adapted from rainlanguage/rain.metadata#298, for rainlanguage/rainix#365
#298 is the reference. What had to change here, and why — this is the seam the
reusable workflow has to be able to straddle:
networks.json. 2024 02 16 app open larger size #298 copiessubgraph/plus the ABIs its manifest names into a temp dir and synthesises a
networks.jsonthere, because rain.metadata's manifest is a templatecarrying no
address/startBlockandgraph build --networkwrites thatnetwork's values back into the manifest it builds. raindex's
subgraph/subgraph.yamlalready carriesnetwork,addressandstartBlock, so nothing here passes--network, nothing rewrites themanifest, and the build runs in place.
--networkis the whole reason forthe temp tree — it is not part of the intersection, it is conditional on a
network being selected at build time. A reusable workflow has to take that
as an input rather than always doing it.
names the chain
anviland rewrites the manifest onto that network. Herethe compose file declares
ethereum: sepolia:http://host.docker.internal:8545— the name graph-node is told is the one the committed manifest already
declares — and anvil runs with
--chain-id 11155111so that name is not alie. The chain name is a per-repo input derived from the manifest.
forge soldeer installand noforge build. 2024 02 16 app open larger size #298 needs both becauserain.metadata's manifest points at ABIs forge emits. raindex commits
subgraph/abis/*.json—deploy-subgraph.yamlsays so in as many words —so those two steps drop out entirely. An optional pre-build step, not a
fixed one.
graph codegen. 2024 02 16 app open larger size #298 runs it. raindex commitssubgraph/generated/, andsubgraph-deploybuilds straight off it; runningcodegen here would rewrite a committed directory and put the
git diff --exit-code -- subgraph/assertion at risk of firing for a reasonthat has nothing to do with the schema.
nix develop. raindex's default shell carries the rust and wasm toolchains,so the job splits:
.#sol-shellforanvil/castonly,.#subgraph-shell(node + graph-cli, no rust, no foundry) for deploy and introspection. Both
are the flake's re-exports, so they come from
flake.lock's rainix revrather than live
main, per the comment on those outputs.hand-add
cachix/cachix-actionto its lane, because rain.metadata'ssubgraph lane is a hand-rolled workflow that predates the shared preamble.
raindex's lane already calls
rainix-subgraph-test.yaml, so this job usesrainlanguage/rainix/.github/actions/nix-cachix-setup@mainand getscheckout, nix, cachix and the store cache from it. 2024 02 16 app open larger size #298's "Also here" cachix
fix has no analogue here — which is the clearest signal that the preamble is
already correctly upstream and the reusable workflow should call the
composite the same way.
name and subgraph name all differ (
crates/subgraph/schema/raindex.graphql,raindex.graphql.generated,raindex-api-schema,rain/raindex).Carried over unchanged, and therefore the actual intersection: the separate
compose file (raindex has the same
subgraph/docker-compose.ymlcollisionhazard with
--abort-on-container-exit); thegraphql15.5.0 direct pin —raindex's lock has the identical shape, graph-cli pinning
15.5.0against@float-capital/float-subgraph-uncrashablewanting^16.6.0, with npm'shoist tie-break today landing on 15.5.0 and nothing holding it there;
print-api-schema.jsbyte for byte, includingAbortSignal.timeoutand theretry loop;
lexicographicSortSchema+printSchema; thediff -u; theartifact upload; and the
graph-node:v0.35.1/postgres:14/kubo:v0.17.0pins.
One limitation worth stating: the assertion is only ever "matches what
graph-node v0.35.1 derives". That pin is the oracle. If the deployment
target's graph-node moves, the pin has to move with it, and the snapshot churns
when it does.
