Via @beatthem on #8, Bugjar apparently doesn't run on Python 2.6 due to changes in the Bdb API - specifically the 'skip' parameter.

Running bugjar bugjar_demo1.py a b gives this error:

First, I must say thank you for creating so simple but powerful debugger for python.

Second.
I have troubles with using Bugjar on Django (1.4.10) and Python 2.6.

1. There is "skip" parameter for Bdb in Python 2.7, but not 2.6 - so python 2.6 raises exception.
2. If I omit this parameter, django doesn't work well with Bugjar - If I let django run in debugger, but set breakpoint before, first few seconds (~20) Django application doesn't respond (It may be django startup time, don't know, but after I click few times Run - application starts to respond, BUT it doesn't stop at breakpoints. Maybe it new Django threading server? Even with --noreload option (bugjar manage.py runserver 8000 --noreload) it doesn't stop at breakpoints.

I am using the ARI-Py and Swagger-Py libraries to interface with the Asterisk open-source phone system. When debugging one of my modules, Bugjar crashes with the following traceback:

Traceback (most recent call last):

RuntimeError: maximum recursion depth exceeded while calling a Python object

I know about the lack of tail recursion in the language, but everything works perfectly fine outside the debugger.

I just installed bugjar in Ubuntu 13.04 to give it a try at debugging a Django application but I'm getting an exception thrown when I try to execute it with bugjar ./manage.py runserver.

This is the whole error:

Any thoughts on what could be the cause and how to fix it?

I ran >> bugjar in my terminal and received the message below. I thought I had successfully installed bugjar.

Need help making sense of this Traceback. Thanks **/

bugjar chokes on library.

There seems to be a escape issue when bugjar attempts to load a file via the GUI.

In the screenshot above, I am attempting to load a django project called "testproject" and an app called "testapp" using the command "bugjar manage.py". When the GUI loads, I am going File -> Open -> settings.py

Notice that the 't' in testproject is missing and is replaced by a tab which would happen if the ...\testproject\ is being interpreted as a tab character.

The problem seems to be on line 385 of view.py and can be avoided by doing the following.

# ... select the new filename
f = filename.replace("\\", "\\\\")
self.breakpoints.selection_set(f)
#self.breakpoints.selection_set(filename)

Note: I am not trying to imply that the above is a good solution. Simply that it shows the source of the issue.

The current release on pypi is broken for python 3 since it imports Tkinter.
It might be time to do a release on pypi again?

No clue how to solve this...

This computer has python3 as the default python runtime. Trying to run bugjar triggers this error:

    from Tkinter import *
ImportError: No module named 'Tkinter'

From what I can deduce this is because with python3, Tkinter should be all lowercase, i.e. 'tkinter'.

Here's what I tried, and here's the traceback:

When playing with testing bugjar on Windows 8 I discovered that the UI component will consistenly crash with the following error on the console.

TclStackFree: incorrect freePtr. Call out of sequence?

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

Based on this link, it seems that this error is caused by more than one thread accessing the tk event loop.

My hypothesis is that the Debugger is invoking callbacks such as MainWindow.on_stack and MainWindow.on_line from the non tk event thread.

Below is an attempt to rectify this situation using the python Queue object.

class MainWindow(object):
    def __init__(self, root, debugger):

        # <snip>------------

        self.queue = Queue.Queue()
        self.root.after(200, self.debugger_update)

        debugger.start()

    def debugger_update(self):
        try:
            while 1:
                func_name, args = self.queue.get_nowait()
                handler = getattr(self, func_name)
                handler(*args)
        except Queue.Empty:
            pass
        self.root.after(100, self.debugger_update)

    # <snip>------------

    def on_stack(self, stack):
        self.queue.put(('_on_stack', (stack,),))

    def _on_stack(self, stack):
        # <snip>------------

Using the above setup, I have found that I am able to step through the code without encountering the same freePtr issue.

I work under Ubuntu 14.04 and try to debug my python code written in python 3. Is there a possibility to debug python 3?

This would suit debugging a process in vagrant, but would have use beyond that too.

The question is, is this even possible? A cursory look seems to suggest it should be, so leaving this here as a place to continue the convo.

When stopping debug Django application, bugjar hangs for some time and then errror is raising in console

of MainWindow helps

The bugjar debugger will throw a circular reference exception if you debug the files below.

When twisted does a reactor.stop it presumably does something that kills the socket that bugjar is using. When you try to exit bugjar it complains (traceback and code to repro below)

I haven't delved deeper because this looks like a trivial fix. If you want, I can though :)

Tool is looking great mate! Definitely going to be helping any way I can!
