pdb and generators
by Guido van Rossum June 27, 2011

June 27, 2011

When debugging generators (especially when using them as coroutines) I often want 'next' to step over a yield statement/expression, instead of the current behavior, which is to step out of the frame, since pdb doesn't seem to see the difference between yield and return. Or I could live with a separate command to step over the yield. Has anyone looked into this yet? I found a question about this on StackOverflow.com but the answers were particularly unhelpful, so I'm guessing I'm not the first … [View More]

Patching builtin_id to allow for C proxy objects?
by Tom Whittock June 27, 2011

June 27, 2011

Hi all. I'm writing a module to proxy C++ objects into Python for a large C++ application. There are hundreds of thousands of C++ objects, some of which are temporary while others are very long lived. Currently every time one of these objects is accessed from Python, a new "myproxy" instance is created. So if I were to access the same field of an object twice, I would receive two python objects proxying the same underlying C++ object. This messes up "id" and "is", and is causing me issues … [View More]

PEP 382 sprint
by Barry Warsaw June 22, 2011

June 22, 2011

Hi folks, Yesterday, 6 Washington DC area Pythonistas met to work on PEP 382. I wrote up a summary based on my notes and blogged about it here: http://www.wefearchange.org/2011/06/pep-382-sprint-summary.html Hopefully, the other participants will correct my mistakes and fill in the holes. A few other things to mention: * I resurrected the import-sig in order to shepherd PEP 382 to landing in Python 3.3. If you're at all interested in helping out, please join the mailing list: … [View More]

Is there any fun with benchmarks
by anatoly techtonik June 22, 2011

June 22, 2011

I run across a snippet in SCons.Util (don't worry, I've double-checked To: field) that claims it is faster than os.path.splitext() while basically doing the same thing. def splitext(path): "Same as os.path.splitext() but faster." sep = rightmost_separator(path, os.sep) dot = path.rfind('.') # An ext is only real if it has at least one non-digit char if dot > sep and not containsOnly(path[dot:], "0123456789."): return path[:dot],path[dot:] else: return … [View More]
