1.为什么cp的方式更新运行中进程的so,程序会coredump 2.采用什么方式更新已经加载了的so,就可以避免coredump 我们的公共组件绝大部分都支持so形式的自定义插件,比如s++,qzhttp,ttc。在不停进程更新so的时候往往会产生coredump,并且肯定core得莫名其妙,core得让人心碎。 先看一下用cp的方式更新so的时候发生了什么事情...

Commit 079148b ("coredump: factor out the setting of PF_DUMPCORE") cleaned up the setting of PF_DUMPCORE by removing it from all the linux_binfmt->core_dump() and moving it to zap_threads().But this ended up clearing all the previously set flags. This causes issues during core genera...
