What should we do with cProfile?
by Alexandre Vassalotti June 4, 2012

June 4, 2012

Hello, As per PEP 3108, we were supposed to merge profile/cProfile into one unified module. I initially championed the change, but other things got in the way and I have never got to the point of a useful patch. I posted some code and outlined an approach how the merge could be done. However, there still a lot of details to be worked out. So I wondering whether we should abandon the change all together or attempt it for the next release. Personally, I slightly leaning on the former option … [View More]

whither PEP 407 and 413 (release cycle PEPs)?
by Brett Cannon June 4, 2012

June 4, 2012

Are these dead in the water or are we going to try to change our release cycle? I'm just asking since 3.3 final is due out in about 3 months and deciding on this along with shifting things if we do make a change could end up taking that long and I suspect if we don't do this for 3.3 we are probably never going to do it for Python 3 series as a whole.

JITted regex engine from pypy
by Maciej Fijalkowski June 3, 2012

June 3, 2012

Hi I was reading a bit about the regex module and I would like to present some other solution into speeding up the re module for Python. So, as a bit of background - pypy has a re compatible module. It's also JITted and it's also exportable as a C library (that is a library you can call from C with C API, not a python extension module). I wonder if it would be worth to put some work into it to make it a library that CPython can use. On the minus side, the JIT only works on x86 and x86_64, on … [View More]

Python 3.3 on Windows 2000
by "Martin v. Löwis" June 3, 2012

June 3, 2012

It seems that by moving to VS 2010, we have killed Windows 2000 support, for the same reason VS 2012 would kill XP support: Windows 2000 apparently won't recognize the .exe files as executables anymore. I haven't actually tested this: can somebody please confirm? A year ago, Brian put a statement into PEP 11 that 3.3 would support Windows 2000 still, but with a warning. Under my recent PEP change, Windows 2000 does not need to be supported anymore since 13.07.2010, when Microsoft's extended … [View More]

Like Python? Like Italy? Like meetings? Then I've got a treat for you! I'll be chairing a Python Language Summit this July in historic Florence, Italy. It'll be on July 1st (the day before EuroPython starts) at the Grand Hotel Mediterraneo conference center. Language Summits are when the Python core contributors step away from their computers and get together for a day to argue in person. Email me if you're interested in attending; I can send you the final details and simultaneously … [View More]

setprofile and settrace inconsistency
by Alon Horev June 1, 2012

June 1, 2012

Hi, When setting a trace function with settrace, the trace function when called with a new scope can return another trace function or None, indicating the inner scope should not be traced. I used settrace for some time but calling the trace function for every line of code is a performance killer. So I moved on to setprofile, which calls a trace function every function entry/exit. now here's the problem: the return value from the trace function is ignored (intentionally), denying the … [View More]

a new type for sys.implementation
by Eric Snow June 1, 2012

June 1, 2012

The implementation for sys.implementation is going to use a new (but "private") type[1]. It's basically equivalent to the following: class namespace: def __init__(self, **kwargs): self.__dict__.update(kwargs) def __repr__(self): keys = (k for k in self.__dict__ if not k.startswith('_')) pairs = ("{}={!r}".format(k, self.__dict__[k]) for k in sorted(keys)) return "{}({})".format(type(self).__name__, ", ".join(pairs)) There were other options for the … [View More]
