As noted by @targos in #60429 (comment), the implementation of
total_allocated_byteschanges the ABI. This PR changes original V8 implementation to a version where there's no addition ofHeapStatistics::total_allocated_bytes_to V8'sHeapStatistics, and instead we get such values usingIsolate::GetTotalAllocatedBytes. This also changes code introduced by #60573 to use this new API on eitherv8.getHeapStatistics()andWorker::GetHeapStatistics. The goal here is to maketotal_allocated_bytesback portable to previous versions, but keeping thev8.getHeapStatistics()API stable once users transition from v25 to future versions. It also solves the ABI change introduced by https://github.com/nodejs/node/pull/60429/filesThere's also a fix on documentation text with missing
.and updating the code snippet to includetotal_allocated_byteson output.
