"readelf -n /usr/sbin/mysqld" fails to show any NT_STAPSDT notes. If you installed mysql-{client,server}-5.5-dbgsym, you should be able to use .function() etc. probes ... but something's broken in the ubuntu build system: % dpkg -l 'mysql-server-5.5*' ii mysql-server-5.5 5.5.44-0ubuntu0.14.04.1 amd64 MySQL database server binaries and system database setup ii mysql-server-5.5-dbgsym 5.5.44-0ubuntu0.14.04.1 amd64 debug symbols for package mysql-server-5.5 % stap -L 'process("/usr/sbin/mysqld").function("*")' [empty!] % readelf -n /usr/sbin/mysqld [...] Build ID: 7c5b991d6ba0d7722a41f9a39e2915f6a354a1c7 % dpkg -L mysql-server-5.5-dbgsym | grep 5b99 [empty!] So the dbgsym package doesn't contain debuginfo for that actual build, despite the identical version numbers. Please raise this problem with ubuntu. The mysql-client-5.5{-dbgsym} peers appears less broken: % stap -L 'process("/usr/bin/mysqldump").function("*")' [... lots of delicious stuff ...] - FChE -- Gareth Cloud Computing, OpenStack, Distributed Storage, Fitness, Basketball OpenStack contributor, kun_huang@freenode My promise: if you find any spelling or grammar mistakes in my email from Mar 1 2013, notify me and I'll donate $1 or ￥1 to an open organization you specify. -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
