…nothing Re-lands the change from #1192, which was merged but never reached `main`. Drivers are deliberately not shipped, so "driver not installed" is a normal state users hit by design rather than an edge case. `driverSearchRoots()` returns only directories that exist, so on a machine that has never installed a driver it returns nothing and the error ended in a bare "Searched 0 locations:" — a colon with nothing after it, naming nowhere to look. Say plainly that there was nothing to search, and name the `node_modules` directory the printed install command creates. Resolution behaviour is unchanged; this is the error text and one branch. Why this is reappearing: #1192 was squash-merged into its base branch, `fix/warehouse-driver-bootstrap` (#1122), rather than into `main`. #1122 had squash-merged to `main` 43 seconds earlier, so main's snapshot was already taken and this change was never carried across. Its merge commit `e005323` has the single parent `c49149a` — #1122's head, which is not an ancestor of `main` — and #1122 was the only PR from that branch, so nothing else was going to bring it over. Verified against live `main` rather than inferred: constructing `DriverNotInstalledError` with an empty searched list on `babc7cb` prints Searched 0 locations: with nothing after the colon, and none of this commit's text. The content is the cherry-pick of #1192's squashed result onto `main`. Ignoring blob hashes and hunk offsets it is byte-identical to that commit's own diff, and it applied without conflict, which independently confirms `main` already carries #1122's version of both files. Two tests, unchanged from #1192: the empty case must not render "Searched 0 locations:" and must name the install directory, and the populated case must still list the roots it actually searched.

ChangesDriver error reporting
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to This PR only clarifies the missing-driver error and does not change driver resolution. The added tests may interfere when run concurrently because they share environment and temporary-directory state, potentially causing flaky results; the change is mergeable with owner awareness or a follow-up to serialize or isolate those tests.

Bun 1.3.14 bun:test default test concurrency tests within a file across test files process isolation
💡 Result:
In Bun's test runner, concurrency and process isolation are handled as distinct mechanisms [1]. Concurrent Test Execution (Within a File) By default, Bun executes tests sequentially within each file [2][3]. You can enable concurrent execution using the --concurrent CLI flag, which allows asynchronous tests in the same file to run in parallel [2][1]. You can also opt-in specific tests or groups by using test.concurrent(...) or describe.concurrent(...) [4][1][5][6]. When concurrency is enabled, the maximum number of tests that can run simultaneously is 20 by default, a limit which can be adjusted with the --max-concurrency flag [2][3][4]. Individual tests or groups can be forced to run sequentially even when concurrency is enabled by using test.serial(...) or describe.serial(...) [4][5][6]. Note that concurrent tests within a file share the same process and event loop [1]. Parallel and Isolated Test Execution (Across Files) To run test files in parallel across CPU cores, you use the --parallel flag [2][1]. By default, Bun runs all tests in a single process to provide faster startup and shared memory [7]. Using --parallel spawns multiple worker processes, which effectively provides process isolation between different test files [1]. Each test file is executed in its own process when --parallel is used, preventing one file's global state or crashes from impacting others [1][7]. Summary of Key Flags - --concurrent: Enables concurrent execution of tests within the same file [2][3]. - --max-concurrency: Sets the maximum number of concurrent tests (default: 20) [2][3]. - --parallel: Runs test files in parallel across CPU cores, utilizing separate worker processes for isolation [1].

Serialize this suite under Bun concurrent test mode. process.env, savedEnv, and tmpRoot are shared module state. With --concurrent, one test can overwrite another test's environment snapshot or temporary directory, causing incorrect resolution and cleanup. Use serial execution or per-test isolation.

Issue for this PR
Closes #1191
This re-lands #1192, which was merged but never reached
main. #1191 is still open because of that, not by oversight.Type of change
What does this PR do?
Why identical work is reappearing. #1192 was squash-merged into its base branch,
fix/warehouse-driver-bootstrap(#1122), rather than intomain. #1122 had squash-merged tomain43 seconds earlier — 07:33:38Z versus 07:34:21Z — so main's snapshot was taken before #1192's content existed on that branch. #1122 was the only PR fromfix/warehouse-driver-bootstrap, and it is already merged, so nothing was going to carry #1192 across.The mechanics, if you want to check rather than take my word:
e005323has a single parent,c49149a— that is fix(drivers): resolve warehouse SDKs from disk instead of reporting them missing #1122's head, notmain. So it is a squash onto the branch, not ontomain.git merge-base --is-ancestor e005323 origin/mainis false.git merge-base --is-ancestor c49149a origin/mainis also false, because fix(drivers): resolve warehouse SDKs from disk instead of reporting them missing #1122 was itself squashed: its content is onmainonly as the single commitf096d8c.The GitHub API reports #1192 as
merged: true, which is accurate and misleading in equal measure — it merged into the wrong base.The bug, still present on
maintoday. Drivers are deliberately not shipped, so "driver not installed" is a normal state users hit by design rather than an edge case.driverSearchRoots()returns only directories that exist, so on a machine that has never installed a driver it returns nothing, and the error ends in a bareSearched 0 locations:— a colon with nothing after it, naming nowhere to look.The fix says plainly that there was nothing to search, and names the
node_modulesdirectory the printed install command creates. Resolution behaviour is unchanged: this is the error text and one branch.The change is #1192's, not a rewrite. It is the cherry-pick of #1192's squashed result onto
main. Ignoring blob hashes and hunk offsets, the diff here is byte-identical to that commit's own diff, and it applied with no conflict — which independently confirmsmainalready carries #1122's version of both files. Nothing from #1122 is included; that is already onmain.How did you verify your code works?
First, that the premise is true on live
mainrather than inferred from the merge graph. Onbabc7cb, constructing the error with an empty searched list prints:with nothing after the colon, and none of this commit's wording. So the defect is live, not historical.

Note
Low Risk
User-facing error strings only in
packages/drivers; no changes to install or resolution logic.Overview
When optional warehouse drivers are missing and
driverSearchRoots()returns nothing (typical on first run before any managednode_modulesexists),DriverNotInstalledErrorno longer ends with a uselessSearched 0 locations:line. It now states that no searchable locations were found and names the expected managednode_modulespath underdriverInstallDir(), aligned with the printednpm install --prefixhint.When roots were actually searched, the message is unchanged: it still lists count and paths. Driver resolution behavior is untouched.
Tests cover the empty-root wording, the multi-root list, and tighten the integration case to assert the managed root appears in the message.

Fixes the missing-driver error so it names a location when no searchable driver locations are found. The error previously ended in a bare
Searched 0 locations:with nothing after the colon; it now states that no searchable locations were found and names the expectednode_modulesdirectory. This re-lands #1192, which was merged but never reachedmain. Closes #1191. Resolution behavior is unchanged; only the error message is affected.Written for commit 5e9a168.
