刚升级2.4.4之后，微信小游戏遇到一个字体消失的bug，操作就是反复切后台后，系统字体消失了。
官方升级文档明明说是修复了这个bug的，但是测试之后，还是有问题。
手机型号：华为mate10
复现概率： 不高
版本 2.4.5rc2
提个bug，编辑器的cjs/loader.js 去识别和加载esm模块。。。
这个npm包是同时支持commonjs和esm规范的。按道理来说这个不应该去加载esm规范的
2.4.4正常
复现方式：新建空项目，npm install @ailhc/egf-core
估计是升级最新的electron导致的？或者是合并了3.0的代码？

模块解析去applyExports ，读取package.json，解析路径
function applyExports(basePath, expansion) {
const mappingKey = `.${expansion}`;
//先去解析package.json的exports字段，刚好那个npm包就有exports字段指向index.mjs
let pkgExports = readPackageExports(basePath);
if (pkgExports === undefined || pkgExports === null)
return false;
if (isConditionalDotExportSugar(pkgExports, basePath))
pkgExports = { '.': pkgExports };
if (typeof pkgExports === 'object') {
if (ObjectPrototypeHasOwnProperty(pkgExports, mappingKey)) {
const mapping = pkgExports[mappingKey];
//就去解析脚本路径，并返回出去，index.mjs
return resolveExportsTarget(pathToFileURL(basePath + '/'), mapping, '',
mappingKey);
}
let dirMatch = '';
for (const candidateKey of ObjectKeys(pkgExports)) {
if (candidateKey[candidateKey.length - 1] !== '/') continue;
if (candidateKey.length > dirMatch.length &&
StringPrototypeStartsWith(mappingKey, candidateKey)) {
dirMatch = candidateKey;
}
}
if (dirMatch !== '') {
const mapping = pkgExports[dirMatch];
const subpath = StringPrototypeSlice(mappingKey, dirMatch.length);
const resolved = resolveExportsTarget(pathToFileURL(basePath + '/'),
mapping, subpath, mappingKey);
// Extension searching for folder exports only
const rc = stat(resolved);
if (rc === 0) return resolved;
if (!(RegExpPrototypeTest(trailingSlashRegex, resolved))) {
const exts = ObjectKeys(Module._extensions);
const filename = tryExtensions(resolved, exts, false);
if (filename) return filename;
}
if (rc === 1) {
const exts = ObjectKeys(Module._extensions);
//这里才去读package.json的main字段。。。
const filename = tryPackage(resolved, exts, false,
basePath + expansion);
if (filename) return filename;
}
// Undefined means not found
return;
}
}
throw new ERR_PACKAGE_PATH_NOT_EXPORTED(basePath, mappingKey);
}
解析完路径，创建module对象，去加载
//尝试加载native 模块，没有
const mod = loadNativeModule(filename, request);
if (mod && mod.canBeRequiredByUsers) return mod.exports;
// Don't call updateChildren(), Module constructor already does.
//新建一个模块
const module = new Module(filename, parent);
if (isMain) {
process.mainModule = module;
module.id = '.';
}
Module._cache[filename] = module;
if (parent !== undefined) {
relativeResolveCache[relResolveCacheIdentifier] = filename;
}
let threw = true;
try {
// Intercept exceptions that occur during the first tick and rekey them
// on error instance rather than module instance (which will immediately be
// garbage collected).
if (enableSourceMaps) {
try {
//加载模块
module.load(filename);
} catch (err) {
rekeySourceMap(Module._cache[filename], err);
throw err; /* node-do-not-add-exception-line */
}
} else {
//我调试走了这里进去加载模块
module.load(filename);
}
threw = false;
} finally {
if (threw) {
delete Module._cache[filename];
if (parent !== undefined) {
delete relativeResolveCache[relResolveCacheIdentifier];
const children = parent && parent.children;
if (ArrayIsArray(children)) {
const index = children.indexOf(module);
if (index !== -1) {
children.splice(index, 1);
}
}
}
}
}
加载模块逻辑
Module.prototype.load = function(filename) {
debug('load %j for module %j', filename, this.id);
assert(!this.loaded);
this.filename = filename;
this.paths = Module._nodeModulePaths(path.dirname(filename));
const extension = findLongestRegisteredExtension(filename);
// allow .mjs to be overridden
//**阿这。。。mjs结尾的就不加载了？那为什么拿exports呢？**
if (filename.endsWith('.mjs') && !Module._extensions['.mjs']) {
//直接抛异常了
throw new ERR_REQUIRE_ESM(filename);
}
Module._extensions[extension](this, filename);
this.loaded = true;
const ESMLoader = asyncESM.ESMLoader;
const url = `${pathToFileURL(filename)}`;
const module = ESMLoader.moduleMap.get(url);
// Create module entry at load time to snapshot exports correctly
const exports = this.exports;
// Called from cjs translator
if (module !== undefined && module.module !== undefined) {
if (module.module.getStatus() >= kInstantiated)
module.module.setExport('default', exports);
} else {
// Preemptively cache
// We use a function to defer promise creation for async hooks.
ESMLoader.moduleMap.set(
url,
// Module job creation will start promises.
// We make it a function to lazily trigger those promises
// for async hooks compatibility.
() => new ModuleJob(ESMLoader, url, () =>
new ModuleWrap(url, undefined, ['default'], function() {
this.setExport('default', exports);
})
, false /* isMain */, false /* inspectBrk */)
);
}
};
但是拿到了exports又没法解析。。。
@EndEvil 大神，请教一个问题，
从2.2.2版本升上来遇到
我有个脚本是
用在onLoad的时候尝试对齐组件与canvas及parent节点的
onLoad()
{
let root = this
//这边使用了scheduleOnce来做为延时
this.scheduleOnce( () =>
{
root.tryUpdateLayoutByRules()
})
}
在2.2.2的时候是正常的
但是到了2.4.5就失败了，看起来是没有执行
现在在编辑器中 ，component的scheduleOnce是不会执行的吗？
這個的意思是，因為 v3 有實作，由於 v2 的code差異太大，目前暫時不考慮實作…對嗎？
我们确认下
谢谢，该问题已经修复
2.4.4 cc.tween()没有这三个方法吧：
-
stopAll停止所有缓动 -
stopAllByTag停止所有指定标签的缓动 -
stopAllByTarget停止所有指定对象的缓动
2.4.5有吗
stopAllByTarget 用这个也行
关于 Bundle 压缩类型的支持需求
目前 bundle 的压缩类型，在部分小游戏上已经支持了 zip 压缩
想问一下大大，zip 的压缩类型会有计划支持到原生平台吗？比如 Android iOS
