valgrind on server process
hi i am new to valgrind. I know how to run valgrind on executable files from command line. But how do you run valgrind on server processes like apa开发者_运维百科che/myqld/traffic server etc ..
I want to run valgrind on traffic server (http://incubator.apache.org/projects/trafficserver.html) to detect some memory leaks taking place in the plugin I have written.
Any suggestions ?
thanks, pigol
You have to start the server under Valgrind's control. Simply take the server's normal start command, and prepend it with valgrind
.
Valgrind will attach to every process your main "server" process spawns. When each thread or process ends, Valgrind will output its analysis, so I'd recommend piping that to a file (not sure if it comes out on stderr or stdout.)
If your usual start command is /usr/local/mysql/bin/mysqld
, start the server instead with valgrind /usr/local/mysql/bin/mysqld
.
If you usually start the service with a script (like /etc/init.d/mysql start
) you'll probably need to look inside the script for the actual command the script executes, and run that instead of the script.
Don't forget to pass the --leak-check=full
option to valgrind to get the memory leak report.
