fix(server): apply Effect overrides at pinned-runtime install root by deepso7 · Pull Request #11232 · pingdotgg/t3code

deepso7 · 2026-09-11T12:21:19Z

Summary

Fixes Fresh installs of t3@0.0.40 hang in an npm ERESOLVE loop since @effect/platform-node-shared@4.0.0-rc.114 was published #11208: pinned-runtime install into an empty staging directory ignored published t3 Effect overrides (npm only applies them on the root project), so caret ranges floated onto @effect/platform-node-shared@4.0.0-rc.114 and hung on ERESOLVE until the 10-minute timeout.
Before npm install, resolve the target version's overrides via npm view t3@<version> overrides --json, keep only plain effect / @effect/* version pins (no nested pkg>dep selectors or - removals), and write them into the staging root package.json with dependencies.t3. Install is then manifest-driven (no positional t3@…).
Failed installs now include a bounded stderr/stdout tail on PinnedRuntimeInstallError / BootServiceCommandError so the next failure is diagnosable from the CLI.

Test plan

vp test run apps/server/src/cloud/pinnedRuntime.test.ts
Negative control: empty-prefix npm install t3@0.0.41-nightly.20260911.1533 still hung after 25s looping on ERESOLVE for @effect/platform-node-shared@4.0.0-rc.114
Built this branch's CLI, isolated T3CODE_HOME, ran service install for t3@0.0.40 — finished in ~6s, sentinel + --version OK, resolved effect / platform-node-shared at 4.0.0-beta.103 (not rc.114); LaunchAgent cleaned up afterward
Manual installs of 0.0.40 and the nightly with the narrowed override filter also succeed in a few seconds
Deliberate install failure surfaces a truncated npm stderr tail (unit coverage + ordering regression)

Follow-up

Shipping npm-shrinkwrap.json in the published t3 tarball is still needed so bare npx t3@… fresh fetches stop re-resolving caret ranges. This PR unblocks service update / remote update once a patched CLI is running.

Model and harness: Composer in Cursor.

Summary by CodeRabbit

New Features
- Pinned runtime installations now apply compatible Effect dependency overrides from the published package.
- Installation workflows can fall back to an alternate package-manager route when npm is unavailable.
Bug Fixes
- Improved installation error messages now include a truncated portion of npm’s error output, making failures easier to diagnose.
- Runtime installation behavior is more reliable when dependency overrides are provided in different supported formats.

npm only honors overrides on the root project, so installing t3 into an empty staging directory ignored published Effect pins and hung on ERESOLVE. Write the target's Effect overrides into the staging manifest before install, and surface a truncated npm output tail when install fails.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — The PR changes the production pinned-runtime installation workflow and adds a line-level suppression for the preferSchemaOverJson diagnostic. That suppression falls under the required human-review rule, despite the otherwise focused bug-fix scope.

📝 Walkthrough

Walkthrough

The pinned runtime installer reads Effect overrides from the published package, writes them to a staging manifest, and installs from that manifest. Installation and validation errors include a truncated stderr tail. Tests cover staging, failures, and npm fallback behavior.

Changes

Pinned runtime installation

Layer / File(s)	Summary
Override and output contracts `apps/server/src/cloud/pinnedRuntime.ts`	The installer filters Effect overrides and truncates stderr output to 2048 characters. `PinnedRuntimeInstallError` includes the optional output tail.
Override resolution and staged installation `apps/server/src/cloud/pinnedRuntime.ts`, `apps/server/src/cloud/pinnedRuntime.test.ts`	The installer queries `t3` overrides, writes a staging `package.json`, and runs `npm install` through the shared npm fallback. Tests verify the manifest contents and command arguments.
Failure propagation and fallback validation `apps/server/src/cloud/bootService.ts`, `apps/server/src/cloud/pinnedRuntime.test.ts`	Boot-service validation includes the install output tail. Tests verify failed-install diagnostics, output truncation, repeated npm fallback calls, and permission-failure behavior.

Put stdout before stderr before truncating so a large install log cannot drop the failure reason. Encode the staging manifest through Schema to avoid a preferSchemaOverJson suppression.

Copying publish-time keys like `@effect/vitest>vitest` into the staging root made npm reject the install with "Override without name". Keep only plain effect / @effect/* version pins.

Unexport helpers, stringify the staging manifest directly, keep only a stderr output tail, and drop mirror unit tests for private helpers.

Superseded by #11240, which landed a package-level pin of @effect/platform-node-shared as a smaller alternative to the installer-side overrides approach here.
