workspace's Issues

v8 compile issue: Embedder-vs-V8 build configuration mismatch. On embedder side sandbox is DISABLED while on V8 side it's ENABLED.

add -DV8_ENABLE_SANDBOX to your cmd.

[Symbol.for('nodejs.util.custom.inspect')] can hook your `console.log`

Recent use bson package which a npm package for Node.js, I find the result very strange when log the new ObjectId()

const { ObjectId } = require('bson');
console.log(new ObjectId());

then get this result:

new ObjectId(xxxxxxxxxx)

I find it use Node.js internal logic below:

class ObjectId {
    [Symbol.for('nodejs.util.custom.inspect')]() {
        // other logic
    }
}

it can hook your console.log :-)

xcode init LLDB and envs

• cmd + shift + ,
• set LLDB init file on Info tab
• set CHROMIUM_LLDBINIT_SOURCED = 1 on Arguments tab

构建 chromium，使用 clangd 在 vscode 中进行 intelliSense

只看这两篇就可以了.....

• https://chromium.googlesource.com/chromium/src.git/+/HEAD/docs/clangd.md

V8 Local vs Handle

See: https://groups.google.com/g/v8-users/c/S7_hgrH3cEo/m/Ic1ijihPNQ4J

"Handle" is a historical artifact and will go away completely soon: There will be only v8::Local (normal implicitly handled references to JavaScript object) and v8::Global (explicitly handled persistent references, currently known as "UniquePersistent", but this name will go away, too).

All those handle-related changes in the external API are a bit unfortunate, but it simply took us some time to make the API correct and more or less fool-proof.

document load process tips

• link load css will block renderer and script download/scripting
• DOMContentLoaded will be called back after all script excuted including defer script(does not wait for resource to loaded)
• onload will wait for all resource to loaded

Useful shortcut keys

cmd + 0	在 vscode 中可定位到当前文件的位置
