test(server): resolve the temp dir before matching the symlinked entrypoint

[ylcn91]

What Changed

apps/server/src/entrypoint.test.ts, "matches through a symlinked entrypoint": the expected module URL is now built from realpathSync(real) instead of the raw temp path. One line plus a comment.

Why

Fixes #9389.

isEntrypoint compares the module URL against the realpath of the entry, which is what makes npm/npx-style symlinked entrypoints match. The fixture built its expected URL from the un-resolved temp path. On macOS the temp dir lives under /var, itself a symlink to /private/var, so the two strings never matched and the test failed on every run. Linux CI is unaffected, which is why this only shows up locally on macOS.

The product code is correct. Canonicalizing the fixture path keeps the test focused on the symlink it is meant to exercise.

Before, on macOS:

× matches through a symlinked entrypoint, as npm and npx install it
AssertionError: expected false to be true

After:

Test Files  1 passed (1)
     Tests  5 passed (5)

Server typecheck and lint are clean.

Note

Low Risk
Test-only change; entrypoint detection logic is untouched.

Overview
Fixes a macOS-only failure in entrypoint.test.ts for the symlinked npm/npx entrypoint case (#9389).

The test now builds the expected moduleUrl from NodeFS.realpathSync(real) instead of the raw temp path, matching how isEntrypoint compares against the realpath of entryPath. On macOS, temp dirs under /var (symlinked to /private/var) made the old expected string never match even though production behavior is correct.

Adds a short comment explaining Node URL resolution and the /var symlink. No production code changes.

Note

Resolve temp dir real path in isEntrypoint symlinked-entrypoint test

Updates the test fixture's module URL in entrypoint.test.ts to use the filesystem-resolved real path of the target file. Node resolves module URLs to real paths, and macOS temp directories can be symlinked, which caused the previous assertion to fail.

Summary by CodeRabbit

• Bug Fixes
  • Fixed symlinked entrypoint testing to correctly resolve module URLs to the underlying real file path, including environments where temporary directories use symlinks.

Approvability

Verdict: Approved at f629824

Macroscope's review found this PR approvable — This small change only canonicalizes a temporary test path so the symlinked-entrypoint test works on macOS. Production code, product defaults, and static-analysis configuration are unchanged.

Notes:

• No code objects were reviewed. Approvability was decided on eligibility alone.

Can confirm on macOS: the entrypoint symlink test fails on main exactly as #9389 describes and passes with this change. Same /var to /private/var class I just ran into on the server side, resolving before asserting is the right call.

Note: GPT-6 on behalf of shivam (@shivamhwp).

This branch conflicts with the newer symlink-support guard in main. Please rebase the realpath correction while keeping it.skipIf(!symlinksSupported), so Windows installations without symlink privileges keep skipping the fixture.

[ylcn91]

Rebased onto main. The it.skipIf(!symlinksSupported) guard stays as is; the only change is still the realpathSync on the module URL.

Walkthrough

The symlinked-entrypoint test now resolves the real module path before creating moduleUrl. This prevents macOS temporary-directory symlink resolution from causing a false test failure.
