A clone of pdb, fast and with the remote debugging and attach features.
Implement the most recent Python 3 features of pdb, as defined in the Python 3 pdb documentation. The pdb command line interface remains unchanged except for the new detach and thread pdb commands.
Improve significantly pdb performance. With breakpoints, pdb-clone runs just below the speed of the interpreter while pdb runs 10 to 100 times slower than the interpreter, see Performances.
Extend pdb with remote debugging. A remote debugging session may be started when the program stops at a pdb.set_trace_remote() hard-coded breakpoint, or at any time and multiple times by attaching to the process main thread. See RemoteDebugging
Fix pdb long standing bugs entered in the Python issue tracker, see the News.
Add a bdb comprehensive test suite (more than 70 tests) and run both pdb and bdb test suites.
pdb-clone runs the same source code on all the supported versions of Python, which are:
Python 3: from version 3.2 onward.
Python 2: version 2.7.
See also the README and the project home page.
Report bugs to the issue tracker.
Invoke pdb-clone as a script to debug other scripts. For example:
$ pdb-clone myscript.py
Or use one of the different ways of running pdb described in the pdb documentation and replace:
from pdb_clone import pdb
