This lays the initial groundwork for enabling the use of IsolateGroups. Every isolate in V8 is created within a group. When pointer compression is enabled, all isolates within a single group are limited to a 4 GB shared pointer cage. By default, all isolates in the process share the same group, which means that when running with pointer compression, the entire process would be limited to a single 4 GB shared pointer cage. But, we can create as many IsolateGroups as we want, limited only by the amount of virtual memory available on the machine.

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/v8_prof_processor.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. ↩︎
