Hello,

 

 I have recently started looking into mediawiki source code and trying to understand various codeflow. I am new to php as well.

 

I want to see the stacktrace from database functions. 

I have put following debug line in the function :

 

ob_start();

debug_print_backtrace();

$data = ob_get_clean();

fwrite(STDERR, $data  . PHP_EOL);

 

But I don't see any output in /var/log/nginx/mediawiki.error ( in current setup mediawiki is served by nginx).

 

Any help would be great. Or any other approach to access the stacktrace would also work.

 

Thanks

Sandeep
