Re: Traceback in Logging
The issue is that I am on Python 2.4 which doesnt support func name. I am using filename and lineno now. That does serve the purpose. Thank you, I had not checked all the parameters.

Well, he does say "all logging" and "every logging". And, as I mentioned earlier, there is already support for tracebacks by using the Logger.exception method in an exception handler.

The asyncore standard module has an undocumented compact_traceback() function: #!/usr/bin/env python import asyncore def f(): 1/0 def g(): f() def h(): g() try: h() except ZeroDivisionError: print asyncore.compact_traceback()[3] Output looks like this: % python f.py [f.py||15] [f.py|h|12] [f.py|g|9] [f.py|f|6] Might be of interest. -- Skip Montanaro - s...@pobox.com - http://smontanaro.dyndns.org/ -- http://mail.python.org/mailman/listinfo/python-list
Re: Traceback in Logging
I dont want the whole traceback. I just wanted to know where the log was generated from i.e. which procedure and which line. I have 3/4 points in many procedures where I encounter a small error (not an exception) and want to log it. So having individual names for each looks to be somewhat verbose - esp since the application is >10K LOC. This might be a good item to have in the logging system - along with time and level, just proc name and the line number. Thank you for the help.

If you need LoggingAdapter, you can always copy and paste the relevant code from Python's SVN repository into your own application.

Traceback in Logging
Hi all,
Is it possible to print traceback for all logging?
I have created something like this:
def trace():
import traceback
return ''.join(traceback.format_stack(limit=4)[1:])
And during every logging, append it -
self.logger.info('Data: %s, kwargs: %s Traceback: %s' %(data,
kwargs, trace()))
-->Result<--
2009-01-06 18:52:21,483 - test- INFO
---> Data:, kwargs: {}
Traceback: File "C:\test.py", line 48, in success
super(testObj, self).success(reply, **kwargs)
File "C:\test.py", line 87, in success
self.logger.info('Data: %s, kwargs: %s Traceback: %s' %(data,
kwargs, trace()))
File "C:\test.py", line 151, in trace
return ''.join(traceback.format_stack(limit=4)[1:])
This seems somewhat kludgy. Is it possible in logging mechanism itself
to provide traceback as default?
I use Python2.4, so LoggingAdapter is not there too.
