add a extension function `getOrNull(int index)` on List to get element at the specified index safely. If out of bounds, return null. It can work well with nnbd. ref: [https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/get-or-null.html](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/get-or-null.html)
背景： 开启了大量worker数（128甚至256以上）的服务器 mysql、redis等长连接即便是每个进程1个也会导致占用特别多的连接数； 需要每个进程单独维护连接，切换数据库也比较麻烦（需要重启或每个进程通知到），不便于管理； 使用了2.0的协程后，在大并发情况下，会出现大量的 mysql、redis的频繁打开和关闭连接问题，增加服务器负担； 最终导致的结果就是数据库和redis的压力非常大，而一个业务复杂的大型系统往往数据库是最大的性能瓶颈。 解决思路： 提供跨进程传输客户端的方法sendfd()，recvfd()以及客户端增加setfd()，允许单独开一个进程来管理连接，worker内使用recvfd接收客户端并setfd初始化。 ```php $pool = new Swoole\Proccess\Pool(1, SWOOLE_IPC_SOCKET); $pool->on('WorkerStart', function($pool, $id){ $pool->init(); }); $pool->on('Message', function($pool, $data){ $cli = $pool->getClient(); $pool->sendfd($cli->sock); }); ``` ```php...
I don't want to inject a dev config in prod env.Now the code like below: ``` @dev class DevConfig {} @prod class ProdConfig{} $initGetIt(getIt,environment:prod); ``` but the DevConfig still be...

Like lucene, it can use a customize freeze function that only write if the number of children nodes > MIN, otherwise it will be dropped. This allows only save part...
In macos, the dynamic library name is 'libLLVM.dylib' and it's not ELF format. FFiMe only support ELF format so I can't generate the ffi code. I use the llvm7.php and...

the param type is private _ParameterList, it cause i can't specify type annotation, dart analysis will report this warning (I use flutter project analysis_option)
