[英]node js application is crashing in uv_try_write while using N-API C++ addon on SIGPIPE. how can I handle/prevent the issue?
问题描述
I am facing an issue where node application crashes when OS sends SIGPIPE.
当操作系统发送 SIGPIPE 时，我面临节点应用程序崩溃的问题。 I am using N-API C++ addon for sending/receiving message to socket using Function Callbacks.我正在使用 N-API C++ 插件使用函数回调向套接字发送/接收消息。 is there any way to find the root cause or handle the same so that app does not crashes or prevent the issue by finding root cause?有没有办法找到根本原因或处理相同的问题，以便应用程序不会崩溃或通过找到根本原因来防止问题？

Verify whether the PIC (Position Independent Code) setting while building the native module is ON or not.验证构建本机模块时的PIC （位置无关代码）设置是否为 ON。 If it is currently off, then try setting it ON and then re-build the package.如果它当前处于关闭状态，请尝试将其设置为 ON，然后重新构建包。 If you are using Cmake.js then you could use the following setting.如果您使用的是 Cmake.js，那么您可以使用以下设置。
set_target_properties(${PROJECT_NAME} PROPERTIES POSITION_INDEPENDENT_CODE ON)
