v8: add v8.startupSnapshot utils#43329

joyeecheung · 2022-06-06T13:06:06Z

This adds several APIs under the v8.startupSnapshot namespace
for specifying hooks into the startup snapshot serialization
and deserialization.

isBuildingSnapshot()
addSerializeCallback()
addDeserializeCallback()
setDeserializeMainFunction()

Example snapshot entry point that reads a file from disk, compresses it with gzip and makes it
part of the serialized heap so that the deserialized instance can decompress and log the
content of the file after startup:

'use strict';constfs=require('fs');constzlib=require('zlib');constpath=require('path');constassert=require('assert');const{ isBuildingSnapshot, addSerializeCallback, addDeserializeCallback, setDeserializeMainFunction }=require('v8').startupSnapshot;constfilePath=path.resolve(__dirname,'../x1024.txt');conststorage={};assert(isBuildingSnapshot());addSerializeCallback(({ filePath })=>{console.error('serializing',filePath);storage[filePath]=zlib.gzipSync(fs.readFileSync(filePath));},{ filePath });addDeserializeCallback(({ filePath })=>{console.error('deserializing',filePath);storage[filePath]=zlib.gunzipSync(storage[filePath]);},{ filePath });setDeserializeMainFunction(({ filePath })=>{console.log(storage[filePath].toString());},{ filePath });

Fixes: #42617

Removed the unused isolate which is breaking a build and updated the example a bit to assert isBuildingSnapshot for clarity.

Contributed by Jacob Smith, Geoffrey Booth, and Bradley Farias. nodejs/node#42623 The `node:test` module, which was initially introduced in Node.js v18.0.0, is now available with all the changes done to it up to Node.js v18.7.0. To better align Node.js' experimental implementation of the Web Crypto API with other runtimes, several changes were made: * Support for CFRG curves was added, with the `'Ed25519'`, `'Ed448'`, `'X25519'`, and `'X448'` algorithms. * The proprietary `'NODE-DSA'`, `'NODE-DH'`, `'NODE-SCRYPT'`, `'NODE-ED25519'`, `'NODE-ED448'`, `'NODE-X25519'`, and `'NODE-X448'` algorithms were removed. * The proprietary `'node.keyObject'` import/export format was removed.
