Package: pdbme
pdbme - remote active debugger based on rpdbThis is active fork ofhttps://github.com/tamentis/rpdb.Rpdb is a wrapper around pdb that re-routes stdin and stdout to a socket
handler.Pdbme is Rpdb, which is active. Which means, that while Rpdb open port and waits until you connect to this port, Pdbme connects to your port.So, in other words, you open pdbme-cli tool, ask your app "pdb me please" and your app will pdb you :).Why active?Rpdb opens debugger pon port (default 4444), but it has many drawbacks. Eg - it cannot be used in mutlithreaded or multiprocessing application. Even in non-parallel app, port can be occupied a little while after closing it and app will break trying to open it again.Calling your terminal sounds way better way. It's useful when you want to debug app which can break
simultaneously more than once in a time, and passive mode will refuse to open
port 4444 again.Solution to the problem is:# default host is 127.0.0.1 and default port is 4444
import pdbme; pdbme.set_trace()or, in more complex case, eg. when it's running in other host, in your docker, or sth like thatimport pdbme
pdbme.set_trace(host='192.168.1.120', port=12345)You should have pdbme-cli running on other side of your communication.pdbme-clipdbme-cli is a simple tool, using tmux, tcpwrapper and socat to accept incoming
connections and spawn tmux session for each incoming breakpoint.tcpwrapper comes fromhttps://cr.yp.to/ucspi-tcp.html(available in many distros and in MacOS brew)socat -http://www.dest-unreach.org/socat/Installation in CPython (standard Python)pip install pdbme(not yet on PyPi)orpip install git+https://github.com/mahomahomaho/pdbmeTrigger rpdb with signalset_trace()can be triggered at any time by using the TRAP signal handler.
This allows you to debug a running process independantly of a specific failure
or breakpoint::import pdbme
pdbme.handle_trap()

# As with set_trace, you can optionally specify addr and port
rpdb.handle_trap(host="0.0.0.0", port=4441)Callinghandle_trapwill overwrite the existing handler for SIGTRAP if one has
already been defined in your application.Author(s)Łukasz Machmaho@pagema.net-http://pagema.net/based on work of rpdb author:

active session (@kenmanheimer)Extend backwards compatibility down to Python 2.5 (@kenmanheimer)0.1.4 (2014-04-28)Expose the addr, port arguments to the set_trace method (thanks to @niedbalski).0.1.3 (2013-08-02)Remove a try/finally that seemed to shift the trace location (thanks to k4ml@github).0.1.2 (2012-01-26)Catch IOError raised by print in initialization, it may not work in some
environments (e.g. mod_wsgi). (Menno Smits)0.1.1 (2010-05-09)Initial release.
