error code and message are generated at compile time by reading a json
file which contains information of elements for each error code. This
framework provides error handling and ability to do more cleaner log
messages to users.
error-codes.json file contains error description is below format
{
"ERR_NAME": {"code": ERR_NUM,
"message": {"LOCALE": "ERR_MESSAGE"}}
}
At compile time autogen.sh calls gen-headers.py which produces C
header file libglusterfs/src/gf-error-codes.h. This header has a
function
const char *_gf_get_message (int code);
which returns respective ERR_MESSAGE for given ERR_NUM.
