fix(relay): production deploys no longer hang while computing the plan19f43f3

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — The patches address deployment-plan hangs and drizzle-kit snapshot paths, with focused regression tests. The new test file disables an Effect static-analysis diagnostic at line 1, requiring human review of that suppression.

Notes:

All code in this push has already been reviewed. Approvability was decided on eligibility alone.

Walkthrough

Two dependency patches change how drizzle-kit receives output paths and how cached settles waiting callers after effect completion. The workspace registers both patches for their specified dependency versions.

Changes: Dependency patch updates

Layer / File(s)	Summary
Normalize drizzle output path `patches/@alchemy.run__drizzle@2.0.0-beta.85.patch`, `pnpm-workspace.yaml`, `infra/relay/src/alchemyPatches.test.ts`	The drizzle-kit wrapper passes an output path relative to the current working directory, or `"."` when the relative path is empty. The workspace registers the patch. A test checks schema diffing with identical old and new props.
Settle cached effects with exit status `patches/alchemy@2.0.0-beta.85.patch`, `infra/relay/src/alchemyPatches.test.ts`	`cached` settles its shared deferred with either the successful value or failure. It caches the result only after successful completion. A test checks that both callers receive the failure.

Explanation

The description clearly explains the production problem, both contributing beta.85 bugs, the patch-based solution, scope rationale, verification results, and the outstanding production-stage verification. It is mostly complete despite using a different heading for the change section and not including a separate Scope and approval heading.

Add a regression test for concurrent Artifacts.cached callers.

The PR changes cached so waiting callers receive a failed effect's exit. No committed test covers this path. The ad hoc script is not part of the change, so a later change can reintroduce the hang without a failing test.

Add one focused test. It should hold the first cached effect pending, start a second caller, and then fail the effect. Assert that both callers receive the failure. Await the Deferred that marks each milestone. Do not use sleeps or polling.

The repository guidelines require a failing test for a state or concurrency bug fix before the fix. They also require focused tests for backend behavior changes.

Requested test scenario

Start the first Artifacts.cached caller and hold its effect pending on a Deferred.
Start a second caller for the same key.
Fail the underlying effect.
Assert that the first and second callers both fail with the same error.

Added in 70e56d09989 (infra/relay/src/alchemyPatches.test.ts). Both tests fail with the patches removed: the second Artifacts.cached caller hangs, and the Drizzle.Schema diff against the relay's existing migrations fails with drizzle-kit's ENOENT. They pass with the patches.

@juliusmarminge Thanks for adding the regression tests and reporting the results with and without the patches.

I could not verify the tests: the sandbox checkout lacks infra/relay/src/alchemyPatches.test.ts and commit 70e56d09989. Please retry verification once that commit is available to the review checkout. This finding remains unverified.

JJulius Marminge1d ago

The test is in infra/relay/src/alchemyPatches.test.ts at the PR head 70e56d09989 (the sibling thread verified that file at this commit). Resolving: the remaining gap is the review sandbox's checkout, not the change.

JJulius Marminge1d ago

Dropped these tests on purpose. They exercise alchemy/drizzle-kit internals, not t3code code, and go away with the patch. Regression coverage belongs upstream: https://github.com/alchemy-run/alchemy/issues/2980 and https://github.com/alchemy-run/alchemy/issues/2981. The fix was verified with a prod alchemy plan (see PR body).

CcoderabbitaiBot1d ago

@juliusmarminge Understood. I withdraw the request to retain these tests in t3code. For these temporary patches, upstream regression coverage is the appropriate scope. Your reported production alchemy plan provides deployment verification; I have not independently verified that run.

Review thread resolved.

_{You are interacting with an AI system.}

CcoderabbitaiBot1d ago

@juliusmarminge You’re right. The sandbox’s missing commit did not establish that the test was missing from the PR. I should have separated that verification limit from the change itself.

Given the later scope clarification in this thread, my request to retain these temporary-patch tests remains withdrawn.

Review thread resolved.

Add a regression test for an existing migration snapshot.

The reported local plan is not a checked-in regression test. The reviewed commit adds no test for this patch. (github.com) Add a focused test that plans against an existing migration snapshot and fails without the path conversion.

As per coding guidelines: “Backend behavior changes ship with focused tests for that behavior.”

@juliusmarminge Verified the tests in 70e56d09989, the current PR head. The Drizzle.Schema test uses an absolute output path and the relay’s existing migrations. The Artifacts.cached test checks that both callers receive the failure.

This addresses the regression-test request. I inspected the source but did not run the tests.

Review thread resolved.

@juliusmarminge Understood. I withdraw the request for repository-local regression tests for these temporary dependency patches. Upstream is the appropriate place for coverage of these dependency internals. Your reported production alchemy plan verification addresses the deployment check.

Review thread resolved.
