test: give each run one temp directory and remove it afterwards by Rinse12 · Pull Request #249 · bitsocialnet/bitsocial-cli

Rinse12 · 2026-11-10T16:07:35Z

Closes #248

Problem

Nearly every test file gets its data directory from tempy's directory(), and nothing removed them. Each npm run test:cli left a few hundred folders, many with a kubo repo, in the OS temp dir. On a tmpfs with an inode cap this used up every inode after a week, and tests then failed with ENOSPC on mkdir.

Change

test/helpers/temp-root.global-setup.ts is a vitest globalSetup. It creates one bsc-test-* directory per run in the OS temp dir and points TMPDIR, TMP and TEMP at it. Test workers and every process they start inherit that, so tempy, os.tmpdir() and the CLIs under test all write inside it.
The teardown removes the directory. Errors are swallowed and the removal retries, because on Windows a process the tests started can still hold a file for a moment.
Before a run it removes bsc-test-* directories older than a day, which a killed run leaves behind.
NODE_COMPILE_CACHE is set to the compile cache's usual place unless it is already set, so the CLIs the tests start do not begin cold on every run.

Testing

test/helpers/temp-root.test.ts checks that os.tmpdir() and tempy land in the run's directory, that the compile cache stays outside it, and that only stale bsc-test-* directories are removed.
Locally on Linux, the number of entries in the temp dir was the same before and after a full run, and the full suite passes. Mid-run, the one run directory held 434 entries.

Summary by CodeRabbit

Chores
- Test runs now use a dedicated temporary workspace that is cleaned up afterward. Older unused workspaces are also removed automatically.
Tests
- Added coverage for temporary workspace creation, cleanup, and preservation of unrelated files and directories.

Test files take their data directories from tempy and os.tmpdir(), and nothing removed them, so every run left a few hundred folders with kubo repos in the OS temp dir. A vitest globalSetup now points TMPDIR, TMP and TEMP at one directory per run and removes it in the teardown. It also removes directories that killed runs left over a day ago, and keeps Node's compile cache where it was.

Walkthrough

Vitest now creates a temporary directory for each test run, directs temporary-file environment variables to it, removes stale run directories, and deletes the active directory during teardown. The setup preserves an existing NODE_COMPILE_CACHE value.

Changes: Test temporary directory lifecycle

Layer / File(s)	Summary
Per-run temporary directory lifecycle `config/vitest.config.ts`, `test/helpers/temp-root.global-setup.ts`, `test/helpers/temp-root.test.ts`	Vitest runs the global setup, which removes `bsc-test-` directories older than 24 hours, creates a run directory, and sets `TMPDIR`, `TMP`, and `TEMP` to that directory. It sets `NODE_COMPILE_CACHE` only when unset and removes the run directory during teardown. Tests check temporary directory selection and stale-directory removal.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other · Severity of issue fixed: Medium

Possibly related issues

Issue 212 reports accumulated test temporary directories. This change addresses the accumulation by using a per-run OS temporary directory and cleaning it up, though it does not use the repository-local directory requested in that issue.

Merge Risk: Low · up to 23e16

This change only affects test infrastructure. A long-idle watch session could lose its temp directory when another run starts, and a failed cleanup would go unnoticed. These are narrow edge cases, so the PR is mergeable with owner awareness.

Full details: Linked Issues check

Explanation

Issue #248 requests one OS-temp directory per Vitest run, routing temp files and child processes into it, removing it at teardown, cleaning up abandoned runs, and preserving Node's compile-cache location. config/vitest.config.ts registers test/helpers/temp-root.global-setup.ts. That setup creates a bsc-test-* directory, sets TMPDIR, TMP, and TEMP, and returns recursive teardown with retries. It removes matching directories older than 24 hours before starting a run. It also sets NODE_COMPILE_CACHE to the original OS-temp cache path only when unset. test/helpers/temp-root.test.ts checks temp routing, cache placement, and stale-directory cleanup.

Explanation

The changes are limited to Vitest setup and tests for issue #248. The compile-cache handling directly supports the issue's requirement to keep spawned CLIs warm. No unrelated change is present in the reviewed diff.

Full details: Docstring Coverage

Explanation

Docstring coverage is 50.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 2 functions across 3 files.

Write docstrings for the functions missing them to satisfy the coverage threshold.

Minor · Stability & Availability · Quick win

Report a failed directory removal.

If a file remains locked after the configured retries, fs.rm rejects and this catch hides the failure. Teardown then reports success while the run directory remains; stale-run cleanup cannot retry it until a later run after the age threshold. Report the path and error so a failed cleanup is visible. Node documents that retries apply only to specified removal errors. (nodejs.org)

Do not delete an active watch run.

If a Vitest watch session stays open for more than 24 hours without changing its run directory, a second run treats that directory as stale and deletes it. The watch session still uses that directory for later tests, so a rerun can fail or lose temporary test data. Check that a run has ended before removing its directory; directory age alone does not establish that condition. Vitest 4 keeps global setup active until watch mode exits. (v4.vitest.dev)
