Are PyCFunctions supposed to invisibly consume self when used as a method?
by Brett Cannon 16 Jun '10

16 Jun '10

The logging module taught me something today about the difference of a function defined in C and a function defined in Python:: import importlib class Base: def imp(self, name): return self.import_(name) class CVersion(Base): import_ = __import__ class PyVersion(Base): import_ = importlib.__import__ CFunction().imp('tokenize') PyFunction().imp('tokenize') # Fails! Turns out the use of __import__ works while the importlib version fails. Why does importlib fail? Because the first argument to the importlib.__import__ function is an instance of PyVersion, not a string. And yet the __import__ version works as if the self argument is never passed to it! This "magical" ignoring of self seems to extend to any PyCFunction. Is this dichotomy intentional or just a "fluke"? Maybe this is a hold-over from before we had descriptors and staticmethod, but now that we have these things perhaps this difference should go away.

So let's try this again: Become a Python contributor at PyOhio ===================================== Working in Python is awesome. Are you ready to work on Python? The quality of Python and the Standard Library depend on volunteers who fix bugs and make improvements to the codebase. If you're interested in joining these volunteers, good for you! Information on core development is right on Python's homepage. However, if you'd like an in-person boost to get you started, come to PyOhio this July 31 - August 3. Two talks will get you up to speed on Python contribution: "Intro to Core Involvement" and "Teach Me Python Bugfixing". Next come two evenings and two full days of Python core sprinting, so you can put your new skills to use with plenty of helpers around. It's classroom learning and real-life practice at one free event! See you there! Core development: http://www.python.org/dev/ PyOhio: http://www.pyohio.org/ Intro to Core Development: http://www.pyohio.org/2010/Talks#A.2320_Intro_to_Core_Involvement Teach Me Python Bugfixing: http://www.pyohio.org/2010/Talks#A.234_Teach_Me_Python_Bugfixing PyOhio sprints: http://www.pyohio.org/Sprints2010 -- - Catherine http://catherinedevlin.blogspot.com/ *** PyOhio 2010 * July 31 - Aug 1 * Columbus, OH * pyohio.org ***

Hopefully that's the dumbest mistake I'll make in this year's PyOhio preparations. Fortunately the PyCon blog can be edited... wish emails could be. No, as I wrote to the talk committee, "There is some overlap between this talk and Dan Buch's submission, though his seems to have a heavier focus on doc and triage work. If they're both selected, I'll work with Dan to see that the talks dovetail well together. I would really *love* to see Dan's talk, this talk, and sprints (weekend sprints AND sprints on the following weekdays) fuse into a great big contribu-palooza that will put PyOhio on the map! Well, we're already on the map." I actually think it'll be ideal if we can get - Your talk midday on Saturday, for a clasically planned introduction on multiple aspects of core involvement - Shortly thereafter, my "teach me" talk, which will be specifically about bugfixing and will focus on points of newbie confusion by means of my own all-natural fumbling. Hopefully some people from your talk's audience will take their brand-new knowledge to participate in the "teach me" session as both teachers and learners... nothing solidifies learning like teaching does. (I think I need to *not* watch your talk until afterward on video, incidentally, to keep my ignorance pure. I might end up as the most ignorant person in the room, which would be perfect.) - That evening, the sprinty goodness begins. -- - Catherine http://catherinedevlin.blogspot.com/ *** PyOhio 2010 * July 31 - Aug 1 * Columbus, OH * pyohio.org ***

Become a Python contributor at PyOhio
by Catherine Devlin 15 Jun '10

15 Jun '10

Thanks to David Murray, we're going ahead with plans to make a full-fledged introduction to core development at PyOhio. We've just started circulating this announcement to drum up interest, so if there are people or groups who you'd like to recruit to the effort, please forward it to them. By the way, I haven't made a peep on this list yet - or even read it - because I'm intentionally preserving my ignorance so that I can be the leader-learner for the Teach Me session. (It's the first time wilful ignorance has actually been a virtue). Anyway, the announcement: Become a Python contributor at PyOhio ===================================== Working in Python is awesome. Are you ready to work on Python? The quality of Python and the Standard Library depend on volunteers who fix bugs and make improvements to the codebase. If you're interested in joining these volunteers, good for you! Information on core development is right on Python's homepage. However, if you'd like an in-person boost to get you started, come to PyOhio this July 31 - August 3. One of our many events is "Teach Me Python Bugfixing", an introduction to working on Python that's guaranteed newbie-friendly (because a newbie is running it). Next come two evenings and two full days of Python core sprinting, so you can put your new skills to use with plenty of helpers around.

Reintroduce or drop completly hex, bz2, rot13, ... codecs
by Victor Stinner 11 Jun '10

11 Jun '10

There are two opposite issues in the bug tracker: #7475: codecs missing: base64 bz2 hex zlib ... -> reintroduce the codecs removed from Python3 #8838: Remove codecs.readbuffer_encode() -> remove the last part of the removed codecs If I understood correctly, the question is: should codecs module only contain encoding codecs, or contain also other kind of codecs. Encoding codec API is now strict (encode: str->bytes, decode: bytes->str), it's not possible to reuse str.encode() or bytes.decode() for the other codecs. Marc-Andre Lemburg proposed to add .tranform() and .untranform() methods to str, bytes and bytearray types. If I understood correctly, it would look like: >>> b'abc'.transform("hex") '616263' >>> '616263'.untranform("hex") b'abc' I suppose that each codec will have a different list of accepted input and output types. Example: bz2: encode:bytes->bytes, decode:bytes->bytes rot13: encode:str->str, decode:str->str hex: encode:bytes->str, decode: str->bytes And so "abc".encode("bz2") would raise a TypeError. -- In my opinion, we should not mix codecs of different kinds (compression, cipher, etc.) because the input and output types are different. It would have more sense to create a standard API for each kind of codec. Existing examples of standard APIs in Python: hashlib, shutil.make_archive(), database API, etc. -- Victor Stinner http://www.haypocalc.com/

ssl
by Kristján Valur Jónsson 07 Jun '10

07 Jun '10

Hello there. I wanted to do some work on the ssl module, but I was a bit daunted at the prerequisites. Is there anywhere that I can get at precompiled libs for the openssl that we use? In general, gettin all those "external" projects seem to be complex to build. Is there a fast way? What I want to do, is to implement a separate BIO for OpenSSL, one that calls back into python for writes and reads. This is so that I can use my own sockets implementation for the actual IO, in particular, I want to funnel the encrypted data through our IOCompletion-based stackless sockets. If successful, I think this would be a useful addition to ssl. You would do something like: class BIO(): def write(): pass def read(): pass from ssl.import bio = BIO() ssl_socket = ssl.wrap_bio(bio, ca_certs=...) I am new to OpenSSL, I haven't even looked at what a BIO looks like, but I read this: http://marc.info/?l=openssl-users&m=99909952822335&w=2 which indicates that this ought to be possible. And before I start experimenting, I need to get my OpenSSL external ready. Any thoughts? Kristján
