Problem

In a project that is already linked, the altimate link picker's "+ Create a quick workspace … here" row always failed — and the error told the user to re-run the command they were already inside.

◇  Currently linked to "jaffle_shop-altimate". Pick a workspace (or create a new one):
│  + Create a quick workspace "jaffle_shop-altimate" here
│
■  Failed to create workspace.
■  This project is already linked to "jaffle_shop-altimate". Re-run `altimate-code link`
   to switch to a different workspace.

The row's own hint promises the opposite: "Creates a new workspace and repoints this project to it (no browser step)."

Cause

createThenBindOrRebind already had a correct rebind branch. It was simply unreachable.

Step one called createAndBindPOST /datamate-project-bindings/, whose server handler pre-checks both identifiers and returns 409 before creating anything — deliberately, so a binding conflict cannot strand a half-created workspace. On an already-linked project that refuses the entire call, so nothing was created and the rebind below it was dead code.

The handler's own comment shows the assumption that broke — "the new workspace exists but the binding still points at the OLD workspace". It does not exist: create and bind are atomic server-side, so the binding conflict takes the creation down with it.

Worth noting the neighbouring "+ Set up in browser" row is correctly hidden when already linked, with a comment explaining this exact 409. One of the two guards was applied; the other was missed.

Fix

Split the two cases, because the server offers two different things:

  • Unlinked — unchanged. createAndBind still creates and binds in one transaction, which is what makes a stranded workspace impossible there.
  • Already linked — create the workspace unbound via POST /datamates/, then repoint through the rebind path that already existed.

The trap this had to avoid

createWorkspaceUnbound sends memory_enabled and knowledge_engine_enabled explicitly. POST /datamates/ is the SaaS/extension creation path and defaults both to false, while the create-and-bind path (_create_datamate_flush_only) sets both true.

Without those two lines the same menu row would hand back a differently-configured workspace depending only on whether the project happened to be linked — memory and the knowledge engine silently off, with nothing surfacing the difference. The comment names the coupling so the two move together if backend defaults change.

Error message

After this change a 409 can only mean another workspace claimed the project mid-selection, so it says that, instead of directing the user back into the command they are already running.

Verification

Against a real backend

Local backend on :5001, tenant hackdev, project bound to workspace 63.

Before — what the old code did:

POST /datamate-project-bindings/  {"name":"jaffle_shop-altimate", <same identifiers>}
  HTTP 409
  detail: This project is already linked to a different workspace

Nothing created, rebind unreachable.

After — what the new code does:

POST /datamates/  {..., "memory_enabled":true, "knowledge_engine_enabled":true}
  -> {"id": 66}

PUT /datamate-project-bindings/by-remote
    {"target_datamate_id":66, "expected_current_datamate_id":63}
  -> {"binding":{"id":44,"datamate_id":66, ...}}

GET /datamate-project-bindings/by-remote
  -> bound to workspace 66 - 'jaffle_shop-altimate'

And the new workspace carries the workspace defaults, not the SaaS ones:

memory_enabled           = True
knowledge_engine_enabled = True

All seeded rows removed afterwards; hackdev restored to its prior counts.

Tests

New test/altimate/workspace/create-workspace-unbound.test.ts — 7 tests stubbing globalThis.fetch, following the skill-sync.test.ts harness (real credentials file, assertions on the request that actually goes out). They pin the two things that would regress silently: that this does not reach the binding router, and that both feature flags are sent.

Mutation-tested rather than assumed — each of these fails the suite:

Mutation Result
drop memory_enabled 1 fail
drop knowledge_engine_enabled 1 fail
post to the bindings router instead 1 fail
remove the id guard 2 fail

Existing suites: test/cli/cmd/link.test.ts + all of test/altimate/workspace/503 pass, 0 fail. Typecheck clean on both changed files. oxlint contributes no new errors (the 4 reported are pre-existing, in unrelated tsconfig.json files).

Note for review

The alternative fix is backend-side: a replace_existing flag on POST /datamate-project-bindings/ would make this atomic and remove the duplicated defaults entirely. That is the cleaner long-term shape, but it is a two-repo change; this keeps the fix in the CLI and reuses the rebind path that already exists.

Ticket: AI-9171


Summary by cubic

Fixes the “+ Create a quick workspace … here” row in both the CLI and TUI on already-linked projects, where it always failed and pointed the user back into the command they were already running. The row now creates the workspace unbound, then repoints the existing binding to it.

  • Unlinked projects keep the atomic create-and-bind behavior; only the already-linked path takes the new two-step route.
  • The unbound create sends memory_enabled and knowledge_engine_enabled explicitly, matching the configureation the create-and-bind path produces.
  • The account is pinned across the create-and-rebind pair so an account switch mid-flow cannot rebind on the wrong tenant.
  • A strict id guard rejects malformed responses instead of coercing values (a boolean would have rebound the project to workspace 1).
  • The rebind's server binding row is what gets cached, replacing locally-derived identifiers the server never stored.
  • 409 messages are split by which create ran: a conflict on the unbound path is reported as another workspace claiming the project.

Written for commit 7b21606. Summary will update on new commits.

Review in cubic

Summary by CodeRabbit

  • New Features

    • Added support for creating a standalone private workspace during altimate link.
    • Existing workspace links can now be safely repointed without creating an unintended project binding.
    • Workspace creation applies memory and knowledge engine defaults automatically.
    • Management links are displayed and opened when available.
  • Bug Fixes

    • Improved handling of workspace creation failures and invalid responses.
    • Prevented rebinding when the active account changes during workspace creation.
    • Clarified conflict messaging when no workspace is created.

The picker's "+ Create a quick workspace here" row always failed when the
project was already linked, and told the user to re-run the command they were
already inside.

`createThenBindOrRebind` already had a correct rebind branch — it was simply
unreachable. Step one called `createAndBind`, and the server's `create_and_bind`
pre-checks both identifiers and 409s *before* creating anything, deliberately,
so a binding conflict cannot strand a half-created workspace. On an already
linked project that refuses the whole call, so nothing was created and the
rebind below it was dead code. The row's own hint promised the opposite:
"Creates a new workspace and repoints this project to it".

Split the two cases:

- unlinked: unchanged — `createAndBind` still creates and binds in one
  server-side transaction, which is what makes a stranded workspace impossible
  there.
- already linked: create the workspace unbound via `POST /datamates/`, then
  repoint through the existing rebind path.

`createWorkspaceUnbound` sends `memory_enabled` and `knowledge_engine_enabled`
explicitly. `POST /datamates/` is the SaaS/extension creation path and defaults
both to false, while the create-and-bind path sets both true — so without this
the same menu row would hand back a differently configured workspace depending
only on whether the project happened to be linked, with memory and the
knowledge engine silently off. The comment names the coupling so the two move
together.

Also corrected the 409 message. After this change a conflict can only mean
another workspace claimed the project mid-selection, so it says that instead of
directing the user back into the command they are already running.

📝 Walkthrough

Walkthrough

The change adds unbound workspace creation, strict identifier validation, account checks, and create-then-rebind flows. The CLI and TUI use this flow for existing bindings and retain atomic creation for unlinked projects. Tests cover API behavior and both linking surfaces.

Changes

Workspace linking

Layer / File(s) Summary
Unbound workspace API and validation
packages/opencode/src/altimate/workspace/api-client.ts, packages/opencode/test/altimate/workspace/create-workspace-unbound.test.ts
createWorkspaceUnbound posts private workspace defaults without project identifiers. It validates that the response id is a positive safe integer and throws WorkspaceApiError for invalid values. Account fingerprint helpers compare API URL and tenant.
CLI branching and rebinding
packages/opencode/src/cli/cmd/link.ts, packages/opencode/test/altimate/workspace/create-then-rebind.test.ts
The CLI uses unbound creation before rebinding an existing project. It verifies the account before rebinding, handles conflicts by path, and falls back to project identifiers and a derived manage URL when needed.
TUI branching and local persistence
packages/opencode/src/plugin/tui/altimate/workspace.tsx, packages/opencode/test/altimate/workspace/create-then-rebind.test.ts
The TUI uses the same separate creation and rebinding flow. It reports failed rebinding, retains the created workspace, and falls back to current project identifiers for local binding state.

WARNING: Pin the account across the two-step operation

createWorkspaceUnbound() and the later rebind each reload credentials independently. If credentials change while creation is in flight, the workspace can be created in tenant A and the rebind sent under tenant B with tenant-local IDs, potentially rebinding to an unrelated workspace with the same ID or leaving the new workspace orphaned. Capture the credential scope before creation and verify it is unchanged before rebind, as the browser handoff path already does.

WARNING: Cache the authoritative binding returned by rebind

The rebind response is discarded, so this fallback stores both fields from the current checkout even when only one identifies the server row. For example, a path-keyed binding whose remote changed is rebound through /by-path, but the cache then contains the new remote; unlink() and memory metadata prefer that remote and can miss the actual row. Retain rebindByMatchedIdentifier()'s response and cache res.binding.repo_remote / project_path, matching the other bind paths.

WARNING: Isolate process-global test state

This assignment persists for the entire loaded suite, while this file also replaces globalThis.fetch. Bun workers can host overlapping test files, so another suite may resolve credentials from this sandbox or send requests through this file's stub; restoring in afterAll/afterEach does not prevent overlap. The existing skill-sync.test.ts explicitly documents this shared-worker hazard. Run this coverage in an isolated subprocess or otherwise guarantee serial isolation for the global mutations.

Make the test fixture per-test and parallel-safe.

OPENCODE_TEST_HOME is changed before the dynamic import and before afterAll is registered. If setup or import fails, the environment value is not restored. globalThis.fetch and captured are module-level state, so overlapping tests can overwrite each other and restore the wrong value.

Use await using tmp = await tmpdir() from fixture/fixture.ts inside each test. Keep captured local, set the environment and fetch stub inside the test, and restore both in a finally block. Serialize these process-global mutations if tests can overlap in one worker. AltimateApi reads Global.Path.home and credentials on each call, so the client import does not need to remain coupled to module-level environment setup.

Review

Overall this is a well-reasoned fix for AI-9171 — splitting the atomic createAndBind (unlinked) from createWorkspaceUnbound + rebind (already-linked) matches the server's actual API contract, and explicitly sending memory_enabled/knowledge_engine_enabled closes a real silent-drift hazard between the two creation paths. Two Major issues are left as inline comments on link.ts. One more Major issue below can't be anchored to this diff since it lives in a file this PR doesn't touch.

Major — The TUI plugin has the identical, still-unfixed bug

packages/opencode/src/plugin/tui/altimate/workspace.tsx:496-546 (createAndBindInline)

This PR fixes the "+ Create a quick workspace" row in the CLI (link.ts). The TUI picker has a structurally identical row wired to createAndBindInline, which unconditionally calls WorkspaceApi.createAndBind at line 509 regardless of whether rebindFrom (i.e. the project is already linked) is set. When the project is already linked, createAndBind 409s before creating anything — the catch block at line 511 shows a warning toast and returns, and the rebind branch at line 525 never executes. This is the exact bug this PR fixes, still present in the TUI's copy of the same flow. Worth applying the same unbound-create-then-rebind split to createAndBindInline before merging, or tracking as an immediate follow-up.

Minor — Shared 409 message misattributes the cause on the unbound-create branch

link.ts:507-524

The ConflictError message ("Another workspace... claimed this project while you were choosing") is shared between both branches, but createWorkspaceUnbound's request carries no repo_remote/project_path at all, so a genuine identity-conflict 409 isn't something that call can produce. If /datamates/ ever 409s for an unrelated reason (e.g. a duplicate name), this message would misattribute it as a binding race. Worth branching the message by which path was actually taken.

Minor — created's inline type is a workaround for two different shapes

link.ts:488

let created: { datamate: DatamateRef; binding?: Binding; manage_url?: string } exists only because the two branches return different shapes. A discriminated union would make it type-safe to access binding/manage_url only where they're actually present, rather than relying on optional-chaining everywhere downstream.

Minor — generic Error instead of a typed error

api-client.ts:432-434

Every other failure mode in this file throws a typed error (ConflictError, PreconditionFailedError, WorkspaceApiError), but the "server returned no usable id" guard throws a bare Error, making it harder for callers to distinguish this failure programmatically. Consider a typed error for consistency.

Missing tests

  • No test exercises createThenBindOrRebind's control flow end-to-end — only the raw createWorkspaceUnbound request shape is tested.
  • No test for the create-succeeds-but-rebind-fails orphan path.
  • No test for the manage_url fallback via manageUrlFor on the unbound path (including the BYOK/null case).
  • No test for the TUI's createAndBindInline already-linked path (would have caught the Major issue above).

// (AI-9171). Create unbound first, then repoint, which is what the row's
// own hint promises.
if (existing) {
const ws = await WorkspaceApi.createWorkspaceUnbound({ name })

Major: This path is now three sequential requests (createWorkspaceUnboundrebindByMatchedIdentifierrecordApprovedBinding), and req() reloads credentials independently on every call. If the active account changes mid-flow, each step could run against a different tenant — and since workspace IDs are tenant-local, a credential change between create and rebind could repoint this project to an unrelated workspace that happens to share the newly-created numeric ID in another tenant.

runBrowserHandoff elsewhere in this file already re-verifies credentials before binding for exactly this class of risk; this new flow doesn't have an equivalent guard.

Suggest pinning one credential snapshot across the whole create/rebind/cache sequence (or having req() accept an explicit snapshot and verify it hasn't changed before the rebind step).

Major: The rebind's response is discarded above — rebindByMatchedIdentifier(...) returns the server's authoritative binding row (Promise<BindingResponse>), but nothing captures it. Because created.binding is undefined on this path, the cache here falls back to the local identifier object instead:

repoRemote: created.binding?.repo_remote ?? identifier.repoRemote ?? null,
projectPath: created.binding?.project_path ?? identifier.projectPath ?? null,

This is the only place in the file that caches a binding from a client-side guess rather than the server's response — every other path here uses res.binding.* directly. In the common case this coincidentally matches, but if a path-matched rebind ever leaves the remote null/stale server-side (or the server canonicalizes an identifier), the local cache will silently diverge from the actual binding row.

Suggest capturing the rebind response and using its binding fields directly, e.g. created.binding = (await rebindByMatchedIdentifier({...})).binding.

Review round on PR #1314. The important one is sahrizvi's: the TUI had the
identical defect and this PR did not touch it.

**The TUI carried the same bug.** `createAndBindInline` called `createAndBind`
unconditionally, so on an already-linked project the server 409'd before
creating anything and the rebind below was unreachable — exactly what this PR
fixes in `link.ts`. Its `rebindFrom` doc asserted the assumption the bug rested
on ("createAndBind succeeds but leaves the binding pointing at the OLD
workspace"); that is corrected too. Both surfaces now make the same split, so
the CLI and the TUI cannot disagree about what that row does.

**`Number()` coerced its way past the id guard.** `Number.isSafeInteger(Number(x))`
accepts `true` as 1, `"7"` as 7 and `[5]` as 5, so a malformed body would have
rebound the project to workspace 1 rather than failing. The type check now runs
before the arithmetic, and it throws a typed `WorkspaceApiError` rather than a
bare `Error`, matching every other failure in that module.

**The account is pinned across the two-step.** Create and rebind resolve
credentials independently, so a re-login in between created the workspace on one
tenant and sent the rebind to another with an id local to the first. Both
surfaces capture the account before the create and refuse the rebind if it
changed. The API key is deliberately not part of the fingerprint: rotating a key
for the same user on the same tenant is not an identity change.

**The rebind's own binding row is what gets cached.** The response was
discarded and the local identifiers cached instead, so a path-keyed row rebound
through `/by-path` was cached carrying a `repo_remote` the server never stored.

**The 409 message no longer guesses.** It was written for the bind path and
claimed a binding race; the unbound create sends no identifiers and cannot
produce one. Split by which call actually ran.

**`created` is a discriminated union** rather than one shape with optional
halves, so `binding` and `manage_url` are only reachable on the path that has
them.

Not changed, with reason: cubic asked for the nested `{datamate:{id}}` shape to
be accepted. `POST /datamates/` declares `response_model=CreateDatamateResponse`
(`{id: int}`) and FastAPI enforces it, so that shape cannot come back from this
endpoint. The strict guard above turns a contract break into a loud failure,
which is the better outcome than silently accepting an unexpected shape.

Tests: `create-then-rebind.test.ts` asserts the *sequence of endpoints* for both
surfaces, because the bug was never in a payload — it was in which request got
sent. Covers unlinked, already-linked, a failed rebind (non-zero exit / error
toast, not a claimed success), and a 409 that must not reach the rebind. Each
one fails if the corresponding fix is reverted.

Thanks — all addressed in 7b21606, including a round of self-review to try to avoid a second pass.

The Major one: the TUI had the same bug

You were right, and this was the important find. createAndBindInline called createAndBind unconditionally, so on an already-linked project the server 409'd before creating anything and the rebind at the bottom was unreachable — the identical defect, in the surface this PR wasn't touching. Fixing one and shipping the other would have left the CLI and TUI disagreeing about what the same row does.

Its rebindFrom doc also asserted the assumption the bug rested on ("createAndBind succeeds but leaves the binding pointing at the OLD workspace"), so that's corrected rather than left contradicting the code below it.

Everything else

Finding Done
409 message misattributes on the unbound branch Split by which call ran. The unbound create sends no identifiers, so it cannot produce an identity conflict
created's inline type Discriminated union — binding / manage_url only reachable on the path that has them
Bare Error in api-client.ts Now WorkspaceApiError, matching the rest of the module
Pin the account across the two-step (kilo/cubic) Captured before the create, re-checked before the rebind, on both surfaces. The API key is deliberately excluded — rotating a key for the same user on the same tenant isn't an identity change and would abort a legitimate flow
Cache the authoritative binding (kilo/cubic) The rebind response is kept and used. A path-keyed row rebound through /by-path was being cached with a repo_remote the server never stored
Reject non-number ids (coderabbit/cubic) Real, and worse than it looks — see below
Test global state (kilo/coderabbit) Documented why the env assignment must be module-scope (the module resolves Global.Path at import), sandbox keyed by pid+clock, original restored in afterAll, fetch restored per-test

On the id guard

Confirmed by running it: Number.isSafeInteger(Number(x)) accepts true → 1, "7" → 7 and [5] → 5. The boolean case is the dangerous one — a malformed body would have rebound the project to workspace 1 rather than failing. typeof now runs before the arithmetic.

One I'm not taking — cubic's nested {datamate:{id}}

POST /datamates/ declares response_model=CreateDatamateResponse, which is {id: int}, and FastAPI enforces it — the nested shape cannot come back from this endpoint. AltimateApi.createDatamate's ?? data.datamate?.id is defensive legacy for a different call. Adding an unreachable branch would just be somewhere for a real contract break to hide; the strict guard turns that into a loud failure instead. Happy to add it if you'd rather.

Tests

New create-then-rebind.test.ts asserts the sequence of endpoints, for both surfaces — the bug was never in a payload, it was in which request got sent, and a payload-shaped test can't see that:

  • unlinked → POST /datamate-project-bindings/ only
  • already-linked → POST /datamates/ then PUT …/by-remote
  • rebind fails → non-zero exit (CLI) / error toast (TUI), never a claimed success
  • 409 on the unbound create → rebind must not run

Plus the coercion cases and the account fingerprint. Mutation-tested rather than assumed — reverting the CLI fix fails 3, reverting the TUI fix fails 2, dropping the feature flags fails 1, and reverting the id guard fails 3.

520 pass / 0 fail across test/cli/cmd/link.test.ts + test/altimate/workspace/. Typecheck clean; lint adds no new errors.

Both flow functions are now exported purely so those tests can reach them — flagged in case you'd rather I found another way.

From my own re-read

Two things I caught and fixed before pushing: a duplicated JSDoc block left the original comment orphaned above createThenBindOrRebind, and I'd left internal scratch labels ("B3", "B4") in source comments that mean nothing to a reader — normalised to the (review, PR #1314) style the file already uses.

Bind the create, rebind, and cache write to one credential snapshot. req() reloads credentials for every request. The CLI and TUI compare accountFingerprint() before calling rebindByRemote or rebindByPath, but those calls can resolve different credentials afterward. The initial fingerprint failure is also converted to null, which skips the guard. recordApprovedBinding() reloads credentials again for the cache scope, so a credential change after rebind can associate the server binding with another tenant's local cache.

Replace the separate sameAccount preflight with a credential-bound request context. Pass that context to the create, rebind, and cache-persistence operations in both callers.

Persist only the server binding fields. Binding permits one identifier field to be null. A path-keyed binding may have repo_remote: null, and a remote-keyed binding may have project_path: null. The current fallbacks copy the caller’s other identifier into the cache, so the local binding can contain an identifier that the server never stored. Apply the same correction in packages/opencode/src/plugin/tui/altimate/workspace.tsx:599-600.

Require serverBinding after a successful create or rebind, then copy serverBinding.repo_remote and serverBinding.project_path directly. Do not fall back to identifier.repoRemote or identifier.projectPath.

Bun 1.3.14 test runner worker process isolation test files parallel same process globalThis process.env

💡 Result:

<search_synthesis>
In Bun, test runner isolation and parallel execution are managed through specific flags that determine how global state and environment variables are handled between test files [1][2]. Worker Process Isolation and Parallelism When running tests with --parallel, Bun automatically spawns multiple worker processes to distribute test files across available CPU cores [1][3]. By default, --parallel enables --isolate, ensuring each test file runs in a fresh global object environment [1]. Even when running on the same worker process, files are isolated from one another by default [1]. If performance is prioritized over isolation, users can pass --parallel --no-isolate to share a single global object and module registry across all files assigned to a specific worker [1][2]. Global and process.env Isolation Under --isolate (which is the default behavior for --parallel workers), Bun performs a "global swap" between test files [3][4]. This process ensures: - A new globalThis is created, removing properties added to the global scope or patched built-ins by previous files [1][3]. - The ESM and CommonJS module registries are cleared, causing files to re-evaluate imports [1][3]. - Resources such as servers, sockets, file watchers, subprocesses, and timers are closed or cancelled [1][3]. - Side effects from process.env modifications (such as changes to TZ, proxy keys, or TLS-related environment variables) are explicitly rolled back to their initial state, preventing leakage between test files [4]. Without --isolate, these cleanups do not occur, meaning state changes, global variable assignments, and environment variable modifications made by one test file may be visible to subsequent test files running in the same process [1][5]. Top results: [1][3][4]

<title>Parallel & isolated test runs | Bun Docs</title> https://bun.com/docs/test/parallel > Run test files across CPU cores with --parallel, isolate files from each other with --isolate, run tests within a file concurrently, and split suites across CI machines with --shard and --timings ... | Flag | Unit of parallelism | What it does | | --- | --- | --- | | `--parallel[=N]` | test files, in processes | Runs files across `N` worker processes (default: number of CPU cores). Implies `--isolate`; `--no-isolate` opts out. | | `--concurrent` / `test.concurrent` | tests within one file | Lets `async` tests in the same file overlap while one is awaiting. | | `--shard=i/n` | test files, across machines | Runs the `i`-th of `n` deterministic slices of the suite. Combine with `--timings` to balance by duration. | ... The main `bun test` process becomes a coordinator. It discovers test files as usual, then starts worker processes and hands each one file at a time. Results stream back as each test finishes, so the output looks the same as a serial run. The coordinator prints each file&`#39`;s results together under its filename, and never interleaves `console.log` output from a test with another file&`#39`;s. ... Workers start lazily. The first worker starts immediately; the coordinator spawns ... rest only once every running worker has been busy for a few milliseconds (`--parallel-delay=`, default `5`). A suite of tiny files therefore runs on ... single worker with no process-spawn overhead, while the first slow file triggers full fan-out ... The coordinator sorts files by path and splits them into one contiguous chunk per worker, so files in the same directory, which usually import the same modules, mostly land in the same process (a chunk boundary can fall inside a directory, and stolen files move). When a worker drains its chunk it steals the back half of the largest remaining chunk from another worker. With `--timings` the coordinator cuts the chunks by recorded duration instead of file count, each worker starts its slowest file first, and an idle worker steals the slowest not-yet-started file from whichever chunk has the most time left. ... Every file is isolated (unless you opt out) ... `--parallel` implies `--isolate`: each file runs in a fresh global object even when two files land on the same worker. Tests that pass with `--parallel` don&`#39`;t depend on state leaked by an earlier file. ... `--parallel --no-isolate` turns that off: each worker keeps a single global and module registry for all the files it is handed, exactly like a serial `bun test` does for the whole suite. Each worker evaluates imports (and `--preload` modules) once instead of once per file, which is the fastest way to run a large suite of small files. The price is that a file can observe whatever an earlier file on the same worker left behind. Preload-level `beforeAll`/`afterAll` hooks still wrap every file, since a worker never knows which file is its last. ... ### Worker environment ... Each worker gets `BUN_TEST_WORKER_ID` and `JEST_WORKER_ID` set to its 1-based index, so tests can pick a distinct database, port range, or temp directory per worker: ... ```ts const dbName = `app_test_${process.env.BUN_TEST_WORKER_ID ?? "1"}`; ``` ... Flags that affect how tests execute (`--timeout`, `--preload`, `--define`, `--coverage`, `--update-snapshots`, `-t`, `--retry`, `--rerun-each`, `--concurrent`, `--randomize`/`--seed`, …) are forwarded to workers. The coordinator handles `--bail` at file granularity: once the failure threshold is reached it starts no new files, but files already running finish. ... If a worker crashes (a test calls `process.exit`), the coordinator reports the file that worker was running as failed, and a replacement worker picks up the remaining files. A crash from a fatal signal aborts the whole run, so later passing files can&`#39`;t mask it. With a single effective worker (`--parallel=1`, or a suite with one test file), `bun test` runs the files in the main process, so `process.exit` ends the run with that exit cod…[truncated] <title>Test runner | Bun Docs</title> https://bun.com/docs/test By default the test runner runs all tests in a single process: it loads all `--preload` scripts (see Lifecycle), then runs every file in one shared global. Pass `--parallel` to spread files across CPU cores instead. If a test fails, the test runner exits with a non-zero exit code. ... ## Concurrent test execution# ... To run test files across CPU cores, see `--parallel`. The flags below control concurrency of tests within a file. ... By default, Bun runs all tests sequentially within each test file. Concurrent execution runs async tests in parallel, which speeds up test suites with independent tests. ... Use the `-- ... ` flag to run all tests ... within their respective files: ... When this flag is enabled, all tests run in parallel unless marked with `test.serial`. ... For a suite with thousands of test files, `bun test` has several knobs that stack: worker processes, isolation level, sharding across machines, and duration-aware scheduling. Parallel & isolated test runs covers each in depth. Here is how they fit together, roughly in order of payoff: ... 1. Use every core: `--parallel`. One worker per core, files handed out one at a time. ... 2. Decide how much isolation you need. `--parallel` gives every file a fresh global, which is the safe default and what Jest/Vitest do. If your files don&`#39`;t leak state into each other (they already pass under plain `bun test`, which shares one global), `--parallel --no-isolate` lets each worker evaluate your imports and preloads once instead of once per file. On suites made of many small files, that is the single biggest win. See how it compares. ... 3. Split across machines: `--shard=i/n`. Deterministic, no coordinator. Each CI job runs one slice, and each slice still uses `--parallel` locally. ... 4. Balance by time, not count: `--timings`. With recorded durations, Bun cuts shards so each gets about the same total time. The split is longest-processing-time style, but keeps path-neighbours together so a worker&`#39`;s module cache stays warm. Each worker starts its slowest file first, and idle workers steal the slowest remaining file. That way, one long file that happened to start last doesn&`#39`;t hold up the run. ... update-timings ... shard writes the ... Every shard must read the same set of timings files for the shards to add up to the whole suite. That is why a run reads the previous run&`#39`;s files (restored from the cache), and why it writes its own where sibling shards still in flight won&`#39`;t pick them up (`next/` above). Add `--no-isolate` to the `bun test` line if step 2 applies to you. ... 6.

Between files the runner drains microtasks, walks usockets contexts to close all sockets, closes `FSWatcher`/`StatWatcher`, cancels timers, kills subprocesses, bumps a generation counter (which `setTimeout`/`setInterval`/`AbortSignal.timeout` check before firing), unprotects the old global, and creates a new one via `Zig__GlobalObject__createForTestIsolation`. `--preload` re-executes in each fresh global. A VM-level `path → SourceProvider` cache (`IsolatedModuleCache.{h,cpp}`) means shared dependencies are transpiled once per process; `module_info` is generated at runtime so cached providers skip the analyze parse via `Bun__analyzeTranspiledModule`. `delete require.cache[key]` evicts. ... - **`--parallel[=N]`** runs a coordinator with up to N worker processes (default = CPU count, configurable via `--parallel-delay=MS` for the lazy-spawn threshold). Files are sorted lexicographically and partitioned into K contiguous `FileRange`s for cache locality; idle workers `stealBackHalf()` from the largest remaining range. Workers run with `--isolate` between files. The version banner shows `N× PARALLEL`. ... IPC is a single duplex channel (`parallel/Channel.zig`): usockets-adopted socketpair on POSIX, libuv `uv_pipe_t` (`ipc=1`) on Windows — same dance as `process.send()`. Length-prefixed binary frames (`parallel/Frame.zig`), event-loop-driven both directions, send-side truncates oversized payloads instead of triggering channel close. Dead workers re-queue their in-flight file once. Cross-worker `--bail` stops dispatching at file granularity. Snapshot writes flush per worker. JUnit and LCOV coverage merge across workers; coverage thresholds enforced regardless of reporter; crashed files get a synthetic ` ` so the merged XML stays schema-valid. Per-file `--randomize` shuffle is seeded by `hash(basename, global_seed)` so the printed seed reproduces order regardless of which worker ran which file. ... All transpiler/resolver flags (`--define`, `--loader`, `--tsconfig-override`, `--conditions`, `--drop`, `--jsx-*`, `--no-addons`, `--no-macros`, `--no-env-file`, `--env-file`, `--feature`, `--preserve-symlinks`, etc.) are forwarded to workers. ...

This integration is part of what makes `bun test` fast. ### NODE_ENV# `bun test` sets `$NODE_ENV` to `"test"` unless it&`#39`;s already set in the environment or in `.env` files. Most test runners do the same. test.ts ``` import { test, expect } from "bun:test"; test("NODE_ENV is set to test", () => { expect(process.env.NODE_ENV).toBe("test"); }); ``` You can override this by setting `NODE_ENV` explicitly: terminal ``` NODE_ENV=development bun test ``` ### TZ (Timezone)# `bun test` uses UTC (`Etc/UTC`) as the time zone unless the `TZ` environment variable overrides it. This keeps date and time behavior consistent across machines. test.ts ``` import { test, expect } from "bun:test"; test("timezone is UTC by default", () => { const date = new Date(); expect(date.getTimezoneOffset()).toBe(0); }); ``` To test with a specific time zone: ``` TZ=America/New_York bun test ``` ## Test Timeouts# Each test has a default timeout of 5000ms (5 seconds). Tests that exceed it fail. ### Global Timeout# Change the timeout globally with the `--timeout` flag: ``` bun test --timeout 10000 # 10 seconds ``` ### Per-Test Timeout# Set a per-test timeout as the third argument to the test function: ``` import { test, expect } from "bun:test"; test("fast test", () => { expect(1 + 1).toBe(2); }, 1000); // 1 second timeout test("slow test", async () => { await new Promise(resolve => setTimeout(resolve, 8000)); }, 10000); // 10 second timeout ``` ### Infinite Timeout# Use `0` or `Infinity` to disable the timeout: test.ts ``` test("test without timeout", async () => { // This test can run indefinitely await someVeryLongOperation(); }, 0); ``` ### Unhandled Errors# `bun test` tracks unhandled promise rejections and errors that occur between tests. If any occur, `bun test` exits with a non-zero code even when no test failed. In both examples below the error happens while the file is being loaded, so the file&`#39`;s tests are not run at all. This helps catch errors in asynchronous code that might otherwise go unnoticed: ``` import { test, expect } from "bun:test"; test("test 1", () => { expect(true).toBe(true); }); // This error happens outside any test queueMicrotask(() => { throw new Error("Unhandled error"); }); test("test 2", () => { expect(true).toBe(true); }); // bun test reports this as "Unhandled error between tests", does not run // this file&`#39`;s tests (0 pass, 1 error), and exits with code 1 ``` ### Promise Rejections# The test runner also catches unhandled promise rejections: ``` import { test, expect } from "bun:test"; test("test 1", () => { expect(1).toBe(1); }); // bun test reports this as "Unhandled error between tests", does not run // this file&`#39`;s tests, and exits with code 1 Promise.reject(new Error("Unhandled rejection")); ``` ### Custom Error Handling# You can set up custom error handlers in your test setup: test-setup.ts ``` process.on("uncaughtException", error => { console.error("Uncaught Exception:", error); process.exit(1); }); process.on("unhandledRejection", (reason, promise) => { console.error("Unhandled Rejection at:", promise, "reason:", reason); process.exit(1); }); ``` ## CLI Flags Integration# Several Bun CLI flags also work with `bun test`: ### Memory Usage# ``` # Reduces memory usage for the test runner VM bun test --smol ``` ### Debugging# ``` # Attaches the debugger to the test runner process bun test --inspect bun test --inspect-brk ``` ### Module Loading# ``` # Runs scripts before test files (useful for global setup/mocks) bun test --prelo…[truncated]

Isolate module-scope environment setup between these test files. bun test uses one shared global by default and evaluates test-file top-level code before running tests. The first file changes OPENCODE_TEST_HOME; the second file then captures that changed value as its “original” value and can restore the wrong sandbox in afterAll. Import-time Global.Path resolution can also bind both files to the first-loaded sandbox. PID-specific directories do not isolate process.env or the module registry.

Run each file in an isolated subprocess, or use a harness that re-evaluates imports per file. Use the repository tmpdir() fixture for sandbox setup. The globalThis.fetch assignment is restored after each test and is not the demonstrated overlap.

The rebind then misses the existing row, leaving the newly created workspace orphaned; pass the matched binding's recorded `repo_remote` or `project_path` through this flow instead.

(Based on your team's feedback about preserving relinked binding identity.) </comment>

P2: When ALTIMATE_WORKSPACE is enabled, the successful TUI tests restore globalThis.fetch before recordApprovedBinding's detached skill and memory work finishes. Await or disable/drain those background jobs in the test so they cannot make real requests or mutate later tests.

P2: Do not mutate process.env at module scope in this test. Default bun test shares the global and module registry, so the other workspace test can capture this sandbox as its original home and reuse its import-time Global.Path; isolate the file or re-evaluate imports per file, using tmpdir() for setup.

Superseded by #1318 — same change, clean branch.

Tracker Leaks was failing on this PR, and not for something fixable in place: it rejects internal tracker keys from the branch name as well as the diff and commit messages, and GitHub does not allow a PR's head branch to be renamed. Re-raising was the only way to get it green. My oversight — I did not check CI when I opened this.

@sahrizvi your review is fully addressed in #1318, including the Major one: the TUI's createAndBindInline had the identical unreachable-rebind bug, and now makes the same split as the CLI. The four bot findings are handled there too, with one declined and the reasoning given.

Sorry for the thread split, and for the three duplicate review comments I left earlier — those were a tooling mistake on my side.
