Description Ravishankar N 2015-06-12 05:26:39 UTC

Description of problem:

I am finding it difficult to decipher the backtrace generated by gf_log_callingfn which prints everything in one line:

[2015-06-11 13:43:05.060464] W [dict.c:499:dict_ref] (--> /usr/local/lib/libglusterfs.so.0(_gf_log_callingfn+0x218)[0x7fcaa9fe9d4a] (--> /usr/loc    al/lib/libglusterfs.so.0(dict_ref+0x44)[0x7fcaa9fe15d1] (--> /usr/local/lib/libglusterfs.so.0(syncop_getxattr_cbk+0x54)[0x7fcaaa03d5c8] (--> /usr    /local/lib/glusterfs/3.6.4beta1/xlator/cluster/replicate.so(afr_get_heal_info+0x2b9)[0x7fca9c8c64d9] (--> /usr/local/lib/glusterfs/3.6.4beta1/xla    tor/cluster/replicate.so(afr_getxattr+0x45b)[0x7fca9c883542] ))))) 0-dict: dict is NULL


Expected results:
A back trace should look like a back trace, with one function per line.
