There is a problem. If node-zone include node-zone, the outside will be replaced by the last child zone data.

const {current} = require('node-zone');

let zone = current.fork('my zone');
zone.data = {test: 'test'};
zone.run(async () => {
    let __current = require('node-zone').current;
    console.log(__current);
    for (let i = 0; i < 50; i++) {
        (async function (i) {
            let zone = current.fork('my zone ' + i);
            zone.data = {i: i};
            // zone.run()
            // zone.set('i', 123456);
            // console.log(current);
            zone.run(async () => {
                (async function () {
                    (async function () {
                        (async function () {
                            let {current} = require('node-zone');
                            // console.log(common.timeHelper.format_ms(), current);
                            console.log(current);
                        })();
                    })();
                })();
            });
        })(i);
    }
    //will lost the current, will show the last child zone data.
    console.log('current zone data', __current);
    console.log('last child zone data', require('node-zone'));
});
return;

Hello... I am back....

const {current} = require('node-zone');

let zone = current.fork('my zone');
zone.data = {test: 'test'};

async function showAsync() {
    let current = require('node-zone').current;
    console.log('showAsync', 'data', current._data, 'name', current._name, 'parent', current._parent._name, 'id', require('async_hooks').executionAsyncId());
}

zone.run(async () => {
    let current = require('node-zone').current;
    for (let i = 0; i < 3; i++) {
        (async function (i) {
            //==============================================================
            //if I remove "await showAsync();", the parent name will be replaced to be the last current.
            //==============================================================
            await showAsync();
            let current = require('node-zone').current;
            console.log('outside', 'data', current._data, 'name', current._name, 'parent', current._parent._name, 'id', require('async_hooks').executionAsyncId());
            let zone = current.fork('my zone ' + i);
            //子zone合并父zone数据
            // zone.data = Object.assign(current._data, {i: i});
            zone.data = {i: i};
            zone.run(async () => {
                (async function () {
                    let {current} = require('node-zone');
                    console.log('inside', 'data', current._data, 'name', current._name, 'parent', current._parent._name, 'id', require('async_hooks').executionAsyncId());

                })();
            });
        })(i);
    }
    current = require('node-zone').current;
    console.log('last', 'data', current._data, 'name', current._name, 'parent', current._parent._name, 'id', require('async_hooks').executionAsyncId());
});

If I remove the await function, the result is different

[caihaibin1991]

keep the await function

showAsync data { test: 'test' } name my zone parent <root> id 1
showAsync data { test: 'test' } name my zone parent <root> id 1
showAsync data { test: 'test' } name my zone parent <root> id 1
last data { test: 'test' } name my zone parent <root> id 1
outside data { test: 'test' } name my zone parent <root> id 10
inside data { i: 0 } name my zone 0 parent my zone id 10
outside data { test: 'test' } name my zone parent <root> id 15
inside data { i: 1 } name my zone 1 parent my zone id 15
outside data { test: 'test' } name my zone parent <root> id 20
inside data { i: 2 } name my zone 2 parent my zone id 20

remove the await function

outside data { test: 'test' } name my zone parent <root> id 1
inside data { i: 0 } name my zone 0 parent my zone id 1
outside data { i: 0 } name my zone 0 parent my zone id 1
inside data { i: 1 } name my zone 1 parent my zone 0 id 1
outside data { i: 1 } name my zone 1 parent my zone 0 id 1
inside data { i: 2 } name my zone 2 parent my zone 1 id 1
last data { i: 2 } name my zone 2 parent my zone 1 id 1
