- Fix mi_parser on Python3. Python3 does not support the __cmp__ operator and rich comparision operators are required, See PEP 207. - Remove the global variables and make a class containing them. Update the gdb class to use the mi_parser session class. Removing the globals means the global lock in the gdb module can be removed.
