`all()`, `get()` and `iterate()` built each row with the `Object::New()` overload that takes names and values. That overload always returns a dictionary-mode object, so no two rows shared a map and every property read was a hash lookup. Build rows from a `DictionaryTemplate` cached on the statement in place of the column names, invalidated on re-prepare. Rows keep their null prototype. Statements whose column names a template cannot express (array indices, duplicates, non-ASCII names, which the template interns as Latin-1) or with more than 64 columns keep the previous path. Add a benchmark that reads every column of each row, since the existing ones only measure building rows.

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. ↩︎
