Subject [mesos][gdb] How to use gdb-mesos-master.sh to debug mesos master code?
Date Wed, 15 Jul 2015 13:31:24 GMT
Hi Mesos dev:

I'm now trying to use gdb-mesos-master.sh to debug mesos master but found
that I cannot hit my break point, can someone help to see if there are
something wrong with my steps?

The following are my steps:

*1) Start gdb-mesos-master.sh*
root@devstack007:/home/gyliu/src/mesos/m1/mesos/build#
./bin/gdb-mesos-master.sh --ip=9.111.242.143 --work_dir=/var/lib/mesos
--log_dir=/root/mesos-log

*2) Set break point*
(gdb) b master.cpp:2498
No source file named master.cpp.
Make breakpoint pending on future shared library load? (y or [n]) n
(gdb) dir /home/gyliu/src/mesos/m1/mesos/src/master/
Source directories searched:
/home/gyliu/src/mesos/m1/mesos/src/master:$cdir:$cwd
(gdb) b Master::accept
Function "Master::accept" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 1 (Master::accept) pending.
(gdb) i b

(gdb) b master.cpp:2498
No source file named master.cpp.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 2 (master.cpp:2498) pending.
*3) Start mesos master*
(gdb) r
Starting program:
/home/gyliu/src/mesos/m1/mesos/build/src/.libs/lt-mesos-master
--ip=9.111.242.143 --work_dir=/var/lib/mesos --log_dir=/root/mesos-log
Traceback (most recent call last):
  File "/usr/share/gdb/auto-load/usr/lib/x86_64-linux-gnu/libstdc++.
so.6.0.19-gdb.py", line 63, in <module>
    from libstdcxx.v6.printers import register_libstdcxx_printers




*4) Start up mesos slave in another console*

*5) Start up python test framework, the code for mesos master did not stop
at my break point*
Thanks,

Guangya
