fix: only install @opencode-ai/plugin into config dirs that can import it - #1292
Conversation
…t it
Config loading (and TuiConfig) forked an `@npmcli/arborist` reify of
`@opencode-ai/plugin` (~60 packages) into every config dir on every start.
Arborist runs in-process, so on a fresh v0.11.0 install it saturated Bun's
event loop: `altimate-code serve` accepted no HTTP request for 5 minutes (the
Altimate Base consent POST only landed once the install gave up) and `run`
froze for ~2.5 minutes after the model had already answered. The starved
EffectFlock heartbeat then made the `npm-install:<dir>` lock look stale, a
second waiter stole it, and the holder's release died with
`ReleaseError: metadata missing`.
The package is only importable by local `{tool,tools,plugin,plugins}/*.{js,ts}`
sources and `file://` plugins under the dir, so gate the install on those (or
on an existing `node_modules`, to keep already-installed dirs current). A bare
config dir, which is what every new user has, no longer installs anything.
- `ConfigPlugin.needsDependencies(dir, plugins)`; used by `Config` and
`TuiConfig`, which had a second unconditional copy of the install
- PURE-mode skip and the `.gitignore` bootstrap are unchanged
- tests: recording `Npm.Service` layer option in `config.test.ts`, nine
cases (bare dir skips, tool/tools and plugins sources, existing
node_modules, in-dir `file://` plugin as string and tuple, npm spec and
out-of-dir `file://` plugin do not install)

Reviewed the original head Standards: no hard violations found. The recording Npm fixtures now have independent state per test. Spec: found and fixed three functional regressions:
Validation: all eight new regression cases failed against the original production code while its nine existing gate tests passed; all 17 pass with the fixes. Added six independent TuiConfig gate tests as well.
A second review of the production fixes found no additional blocking issues. The in-process installer remains unchanged, so configurations that require local dependencies can still incur its installation cost. |

Pushed follow-up 45f63c4f3d: TuiConfig now honors PURE, and the startup regression has automated coverage in PR CI and compiled main/release checks. Existing review threads have been addressed with fixes or test references. Linked #1293 and updated the PR template. When introduced: the fork's config callsite switched from a child-process BunProc install to in-process Arborist in 9e4356302f, June 23, 2026. It entered main through #964 on July 8. The first published beta located was 0.9.0-beta.2 (July 3 UTC); the first stable was 0.9.1 (July 9 UTC / July 8 Pacific), per npm publication metadata. This is the code/release boundary; I have not performance-bisected every historical binary. The multi-minute risk predates 0.11.0. Upstream is affected too. Its Arborist migration #18308 merged April 1. #27971 reports a 298-second request stall; #31463 reports cold-cache hangs; #44684 reports headless startup hangs. Timeout PR #47430, whose author measured 181–370-second stalls, was still unmerged when checked. Warm dependency/cache fast paths explain why many existing installations avoid the expensive path; they do not make upstream immune. Why checks missed it: 3501636dda already documented the fresh-HOME binary hang on June 26 and bypassed installs under PURE. The subprocess harness still defaulted to PURE, while the explicit release-binary smoke only ran Prevention now added:
Mutation proof: restoring unconditional installs fails the source test on two npm requests and the compiled test on failed background installs. The rebuilt fixed binary passes. Follow-up validation: 366 config/TUI tests + 7 serve tests passed, 3 platform skips; compiled smoke passed; all 13 typecheck tasks passed. Marker/tracker checks and workflow YAML validation passed. Full cited investigation is saved in the review worktree and the altimate Obsidian vault. It also records a separate CLI/plugin version mismatch for local-plugin users; that is a compatibility concern, not an established cause of the measured stall, and this PR does not change package-version selection. |

…Rs, settle test stderr
Review follow-ups on the lazy plugin-install change:
- `ConfigPlugin.shouldInstallDependencies(dir, plugins)` folds the
`!Flag.OPENCODE_PURE` check into one helper used by both `Config` and
`TuiConfig`, so the install policy cannot drift between the two call sites
- the compiled-binary cold-start regression moves out of the push-only
`sanity-verdaccio` job into its own `cold-start-regression` job gated like
`typescript`, so a PR that reintroduces the first-run stall fails PR CI;
the `OPENCODE_TEST_CLI` NOTE now cross-references this deliberate, bounded
exception
- `release.yml` reuses the smoke test's `find`-resolved binary path instead of
a second hardcoded copy
- test harness: the stderr tail buffer is bounded at 64 KB and `stderr()`
settles the drain fiber before returning, so
`not.toContain("background dependency install failed")` cannot false-pass
on a chunk that has not landed yet

Pushed The test now waits for process exit and stderr EOF. Bounded capture fails if output was truncated or unreadable, so a missing error in a partial tail cannot make the regression pass. The new controlled-stream tests cover delayed output after the former quiet interval, an early error evicted by the cap, and pipe read failure. This commit changes test infrastructure only. Validation:
The fix has been pushed; merge still depends on the new-head CI results and required reviewer approval. |

[SUGGESTION]: Reuse the fromBunStream wrapper instead of re-implementing the Stream.fromReadableStream boilerplate
test/lib/cli-process.ts centralizes this exact evaluate + onError pattern in fromBunStream ("Centralizes the evaluate + onError boilerplate") and uses it for both stdout watchers; this module inlines a third copy with a hardcoded "stderr stream error" tag. Since cli-process.ts already imports captureStderr from here, moving fromBunStream into this module (or a small shared one) and exporting it would let all three stream-wrapping call sites share one implementation and a consistent error-message format.

Summary by CodeRabbit
Note
Medium Risk
Changes core config-load behavior and when npm runs on startup; mitigated by broad unit/integration tests and release binary checks, but edge cases around symlinked or cross-source file plugins could still differ from prior always-install semantics.
Overview
Stops unconditional
@opencode-ai/plugininstalls in every config directory on startup, which had been blocking cold starts for minutes. Installs now run only when a directory has local tool/plugin sources, an existingnode_modules, or a mergedfile://plugin that resolves inside that dir; PURE still skips installs entirely. The decision runs after all config sources (inline, account, managed, later dirs) are merged, and TuiConfig uses the same gate.CI and regression coverage: a new cold-start job (PRs touching TypeScript + push) and a release step run
fresh-start.test.tsagainst the compiled Linux binary viaOPENCODE_TEST_CLI, with workflow comments clarifying why that exception is safe versus the general subprocess suite.Test harness:
opencode servesubprocess helpers gain deterministic stop, full stderr capture (EOF/truncation-safe), and SIGKILL fallback on teardown; unit tests cover stderr capture.Reviewed by Cursor Bugbot for commit 3beb7bd. Bugbot is set up for automated code reviews on this repo. Configure here.
