A single executable application built with "vfsArchive" mounted its archive at the next free layer, like any file system a program mounts itself, and only in the main thread. A worker had no mount at all, so a path into the archive, such as the main script's __filename, could not be loaded there. Mount the archive at the layer reserved for --vfs-load instead, so it is at the same mount point in every thread, and mount it in each worker as well, with the main script placed at its root just as in the main thread. The worker reads the main script through a new getMainCode() binding, since no main script is handed to it. Unlike the --vfs-load source, the archive needs no provider that a preload could register, so its mount in a worker is not deferred past --import. Since the archive takes that mount point, reject --vfs-load alongside it: --build-sea refuses it in "execArgv", and the executable refuses it at startup when it comes from --node-options or from the execArgv of a worker. Also fix the example in vfs.md, which showed a file system a program mounts itself at layer 0, the layer reserved for these mounts.

Tests for networking related modules may also be present in other directories, but those tests do not make outbound connections. ↩︎
-
All tests inside of this directory are expected to fail. If a test doesn't fail on certain platforms, those should be skipped via
known_issues.status. ↩︎ -
The tests are for the logic in
lib/internal/main/prof_process.jsandlib/internal/v8_prof_polyfill.js. The tests confirm that the profile processor packages the correct set of scripts from V8 and introduces the correct platform specific logic. ↩︎
