9 years ago There is a warning in the docs about sys.exc_info() which is about assigning the traceback object to a variable:
Warning: Assigning the traceback return value to a local variable in a function that is handling an exception will cause a circular reference. This will prevent anything referenced by a local variable in the same function or by the traceback from being garbage collected. Since most functions don’t need access to the traceback, the best solution is to use something like exctype, value = sys.exc_info()[:2] to extract only the exception type and value. If you do need the traceback, make sure to delete it after use (best done with a try ... finally statement) or to call exc_info() in a function that does not itself handle an exception.
which does indeed appear to happen with _:
>>> try:
... raise Exception()
... except:
... _, a, _ = sys.exc_info()
... print(_)
...
<traceback object at 0x1073eedd0>I think compatibility with 2.4 should be dropped by using the as exc syntax.

These three patches make beanstalkc compatible with python 2.4-3.4. Possibly even 2.3, but I don't have that installed anywhere to test.
