runtime/cgo: call C exit to allow global destructors/atexit to run#20713 cmd/cgo: atexit handlers not run#5948 Maybe it's possible to fix or work around this on cgo side: either fix crash if it's not really leg
从Open方法入口可以找到插件加载的整个过程。在linux下的代码在${GOROOT}\src\plugin\plugin_dlopen.go文件中,由于要使用cgo机制调用,C方法的参数需要做一些处理,open方法前半部分主要就是在准备调用C.pluginOpen方法的参数,之后调用了这个方法。 而C.pluginOpen方法的实现实际就在同一个文件中,其实是对dlopen方法的...
GOTRACEBACK=system is like “all” but adds stack frames for run-time functions and shows goroutines created internally by the run-time. GOTRACEBACK=crash is like “system” but crashes in an operating system-specific manner instead of exiting. For example, on Unix systems, the crash raises...
# will produce executable dlsym.test 这个是用于分析coredump的时候获得符号表使用的。 执行测试,获得coredump GOTRACEBACK=crash ./dlsym.test # produced /tmp/core_dlsym.test.29937 如果找不到coredump的位置,执行之前先设置好coredump的写出条件 echo '/tmp/core_%e.%p' | sudo tee /proc/sys/kernel/core_...

// It is ~0 on other goroutine stacks, to trigger a call to morestackc (and crash). stack stack // offset known to runtime/cgo 描述了真实的栈内存,包括上下界 stackguard0 uintptr // offset known to liblink stackguard1 uintptr // offset known to liblink ...
Pointer(mp)) unlock(&sched.lock) // Allocate memory to hold a cgo traceback if the cgo call crashes. if iscgo || GOOS == "solaris" || GOOS == "illumos" || GOOS == "windows" { mp.cgoCallers = new(cgoCallers) } } mcommoninit基本上就是做一些m0的初始化。
