When I was using HTTPServer, the program exited and I encountered a bug in the log coredump。

Hope this helps to solve this log bug.

Hi @PrimeQH,

Can you please share some context plus details, and how this possibly relates to Mender?

HTTPServer was built using the common/http.hpp library. When HTTPServer exited, a log null pointer bug was found. In the function void Stream::DoCancel() {  
…  
log::Debug(“Stream::DoCancel()”);  
…  
}, a logger\_ null pointer appeared, and then in the function  
void Logger::Log\_(LogLevel level, const string &message) {  
if (this-\>logger\_ == nullptr) {  
std::cerr \<\< “Logger is not initialized or destroyed before use” \<\< std::endl;  
return;  
}  
BOOST\_LOG\_SEV(\*this-\>logger\_, level) \<\< message;  
}  
, a coredump was generated when writing the log.

I currently add a null pointer check before writing to avoid the generation of coredump。

@PrimeQH okay… you’re writing a HTTPServer and are using boost, but that’s really the only thing I gather here.

HTTPServer has a logger object, and the global Logger object is used to write logs, and finally the program exits.
