在web平台测试了下 setLocalZOrder方法是正常作用的, 但是在模拟器和原生平台上， 在同一个父节点下的不同子节点 a、b、c 、d 调用setLocalZOrder 设置a层级为 1 ，b层级为2，c层级为3，d层级为4. 然后将d节点隐藏 会导致a节点渲染在 b、c节点之上。 显示上就是a节点遮盖了b、c节点。
在1.5.1上测试 原生和h5 模拟器都是正常的。。。

I'm try to build game by using ndk clang with modified version of build_android.py and Application.mk, which use APP_STL := c++_static instead of gnu_stl.

But libjs_static.a seems built by gcc and gnu_stl which produce some errors like
C:/proj/cocos_creator_test/build/jsb-default/frameworks/cocos2d-x/external/android/armeabi/libjs_static.a(jscntxt.o)(.text+0xb8c): error: undefined reference to 'std::ios_base::ios_base()' during linking.

So my question is how can I build libjs_static.a from source? Then I could use clang and c++_static to build my own libjs_static.a.

Thanks

cocos creator 1.8

in jsb_spine.js

sp.SkeletonAnimation.prototype.setCompleteListener = function (listener) {
    this._compeleteListener = listener;
    this.setCompleteListenerNative(function (trackEntry) {
        var loopCount = Math.floor(trackEntry.trackTime / trackEntry.animationEnd);
        this._compeleteListener(trackEntry, loopCount);
    });
};

if arg listener is null, function setCompleteListenerNative should pass null too.

I'm not sure if this is an issue or bug but I downloaded the latest version of cocos2d-x-lite and then saw this message in the Preference of Cocos Creator.

不应该在 inPlaybackState 的时候才允许获取时间

1. set a string to a label with none overflow
2. get the content size of this string and set the content size to this string
3. change the overflow of this string to clamp

Observed behavior:

1. the label will wrap text

Expected behavior:

1. the label shouldn't wrap text.

引擎使用cocos统计的话，会导致google预发布报告的一个警告，
Your app is using device identifiers (IMEI, MAC address, Build Serial, etc.) and sending identifier data to a remote network address.

This issue is commonly (but not only) found in apps using an outdated Advertising SDK.

To stop receiving this warning, try updating or changing any SDKs or code in your app that may be using device identifiers.

Sending device identifiers is not a best practice for most use-cases and if you're using this identifier for advertising purposes, this may be a violation of Google Play policies and can affect your app’s visibility on the Play Store. To get recommendations on how your app can use identifiers, learn about unique identifier best practices.

libcocosanalytics.jar中有不少读取硬件信息的代码，
(TelephonyManager)paramContext.getSystemService("phone")).getDeviceId()
(WifiManager)paramContext.getSystemService("wifi")).getConnectionInfo().getMacAddress();
统计如今已经不建议直接使用这种硬件信息来指定唯一标识了

在cocos/scripting/js-bindings/script/jsb_prepare.js中的

jsb.registerNativeRef = function (owner, target) {
    if (owner && target && owner !== target) {
        var refs = owner.__nativeRefs;
        if (!refs) {
            refs = owner.__nativeRefs = [];
        }
        var index = refs.indexOf(target);
        if (index === -1) {
            owner.__nativeRefs.push(target);
        }
    }
};

jsb.unregisterNativeRef = function (owner, target) {
    if (owner && target && owner !== target) {
        var refs = owner.__nativeRefs;
        if (!refs) {
            return;
        }
        var index = refs.indexOf(target);
        if (index !== -1) {
            owner.__nativeRefs.splice(index, 1);
        }
    }
};

当子结点很多时，再往里面插入结点，refs.indexOf会遍历子结点，这个会引起性能问题。
有可能改为字典关联(dict)的方式么？

不确定为什么这里这么些，但是这两行最终都会触发jsb的fireEventToScript方法，导致js那边通过
socket.on('message', function () {})监听的话，会被调用两次.

但是控制台上只检测到了以下的log：

最后一条 setCurrentTime 结束的 log 消失了，整个当前的 js 运行环境也 hold 在这里。只有其他 callback 内的方法还在执行。

• Remove cc.TextureCache, add asynchronous native method for loading textures.
• Support to run engine JS scripts without packing them. That will be easier for debugging.
  • Resolve typeof bug in JavaScriptCore

^ This returns true only if there is data. Considering the function prototype and description I have the length pointer to know if and how much data I have (or if I don't have); I would expect to return false when it FAILS not when it makes arbitrary decisions about how much data I should pass from js. An empty buffer is perfectly valid, this is a breaking change for js bindings.

let move = cc.moveTo(this.autoSwapDuration, this.getSwapToPosition(index));
let callback = cc.callFunc(this.onSwapFinished, this);
this.content.node.runAction(cc.sequence(move, callback));

Calling resize() with a smaller size than current buffer does nothing. This breaks all expectations considering how virtually every container out there handles resize() and breaks any chained processors that need a smaller sized buffer.

Everywhere else resize() is resize() but for Data resize() is reserve()

graphicnode onDraw直接调用了 glBlendfunc，而不是 GL::blendFunc，导致glstatecache状态错误，引起其它对象渲染不正确。

cocos2d/cocos2d-x@badd80b

实现自定义action完全是个级别很低的需求，而且这个实现方案实在蛋疼

update：
可以考虑在JSB那一层新增一个ActionInterval的子类来满足这个需求

每个action都发update事件到JS层是什么鬼。。。

在没有网络的情况下，会抛异常！调用者不清楚具体发生了什么。

cocos2d/cocos2d-x#16118
Just asking, if u can add this support to cocos2d-x-lite, we won't have to adopt shader manualy which would be a great help.
Or is there any reason that cocos creator won't use this method. If none, maybe I can do it myself.
Thanks in advance!

RenderTexture seems broken in the lite branch, it doesn't render all visited notes. Attached is the result of the same code running on the 'lite' version that comes with Cocos Creator 1.7 and 'regular' cocos 2dx 3.16.

The test is nothing fancy, takes an jpeg image with 6x6 colored squares, breaks it in separate sprites using the same texture with different rects and renders/saves them to a file using RenderTexture.

我为啥编译的时候会说少了libbox2d呢？删除了依赖，又说链接不了？

When create project with '-l cpp' argument, out ERR message:

You can specify the path of cocos2d-x by argument '-e'.

CCJavascriptJavaBridge.cpp ,callStaticMethod使用args[i].l = call.getEnv()->NewStringUTF(arg.get());获取的字符串，改为通过cocos2d::StringUtils::newStringUTFJNI获取可解决。

graphicnode onDraw直接调用了 glBlendfunc，而不是 GL::blendFunc，导致glstatecache状态错误，引起其它对象渲染不正确。

after creator 1.4, jsb.AssetsManager provide a function "setVersionCompareHandler" that user can define self version compare.
but when AssetsManangerEx class is creating, AssetsManagerEx constructor function is using the default compare function (cmpVersion), because the user version compare handler can not be set when AssetsManagerEx contructor:
the call stack:
AssetsMangerEx:AssetsManagerEx();

AssetsManagerEx:initManifest();

AssetsManagerEx:loadLocalManifest();

Manifest:versionCreator(Manifest *b, handler);

** the call stack end **

中文：
creator 1.4 之后， 热更提供一个 让用户自己自定义比较版本的函数("setVersionCompareHandler"), 但是 js 创建 AssetsMangerEx时，AssetsMangerEx 构造函数只提供了 manifestUrl 路径和 storagePath，这时_versionCompareHandle还没有被赋值，所以在initManifests的时候使用了默认的比较函数，然后在调用堆栈的loadLocalManifest中的如下代码就和用户设想的不一样了，（因为_versionCompareHandle使用的是默认的函数），然后可能导致一直重复更新

请问在JS引擎里增加的属性，在CPP引擎怎么增加
例如：
/**
* @Property {Boolean} demoProperty
*/
demoProperty: {
default: true,
animatable: false,
tooltip: 'demoProperty',
}

Creator创建TTF类型的Label时默认的字体大小是40，如果游戏中不使用40的字体，会存在一个很大的性能问题。比如一个界面有几十个大小为20的Label，此时CCLabel的工作情况如下：

1. 创建CCLabel，Creator传入默认大小为40，此时FontAtlasCache会创建一个FontAtlas，用于存放40大小的文字。而FontAtlas会预先创建一个512x512的Texture
2. 接着Creator将Label字体大小改为20，CCLabel的setTTFConfig被调用，然后FontAtlasCache会再创建另一个FontAtlas用于存放20大小的文字。
3. 问题来了：那个40的FontAtlas因为引用计算变为0，因此被释放掉了。当我创建几十个Label的时候，实际上一直在创建和释放那个40的FontAtlas，也即有一个512*512的Texture，在创建Label的过程当中，不断的被创建出来然后释放掉。

这个在文字信息很多的界面，性能消耗非常明显，我们项目优化掉这个以后，一个可以省掉250ms以上的时间

希望官方想一个更好的方案，我这里给一个建议是，引用计数为0的FontAtlas，不马上释放掉，而是放入一个LRUCache里，方便下次快速重用。
