deprecated methods on array objects
by Jake McGuire 28 Aug '09

28 Aug '09

The python documentation says that the read() and write() methods on array objects have been deprecated since 1.5.1. I assume this is because their semantics are almost the exact opposite of read() and write() on a file-like object; array.read() reads data from a file into the array and array.write() writes data from the array to a file. This causes fatal confusion in code that checks for the existence of read() and write() to determine whether an object is file-like. Code such as httplib. What is the timeline for removing these methods from array? It has been 11 years now. -jake

Re: [Python-Dev] functools.compose to chain functions together
by Peter Harris 28 Aug '09

28 Aug '09

I am personally indifferent to this, even though I had in mind in PEP309, that compose would probably end up in there too. On the one hand, some people will keep on expecting it to be there. The ones that care about it will not be confused: they'll expect compose(f,g)(x) to be f(g(x)) as is proposed. It can't do any significant harm. On the other hand it's not likely to be used even as often as partial, which I always wanted mostly to make anonymous callables for Tkinter, not because of any ivory-tower functional programming bias. And the most common use case of compose() is covered by a one-liner that really doesn't need to be in the standard library. I'll say +0, with the + because if new Python programmers run across compose() in the docs, and aren't familiar with the idea, they can follow a link from there to Wikipedia, and maybe it will give them an idea we haven't thought of for something cool to do with it.

Adding a C Module to python source distribution
by Shashank Singh 28 Aug '09

28 Aug '09

Hi All, I am trying to add a module written in c to python source on Win32 using VC++ 9 Pro. I went through the available documentation but there doesn't seem to be any clear instruction on how to do that. Basically I opened pcbuild.sln in vc++, added the c file (xxx.c) to Modules/ directory. Building the solution after that works fine: xxx.c is compiled (no errors, no warnings) and the python executable gets created. But I am not able to import the module defined in xxx.c using that executable. Do I need to register this module some place else too (setup.py?) ? Any hints and pointers will be appreciated :) --shashank

quick PEP 387 comments
by Brett Cannon 27 Aug '09

27 Aug '09

Is the PEP considering all non-private APIs public even if they are not documented? If so we might want to be up front about that and say so to make sure we are all very careful about making all non-essential APIs private (assuming this PEP gets accepted). And we might want to say that all code in 'test' sub-packages are not subject to backwards compatibility unless documented. I have a ton of support code in importlib.test that I do not want to have to maintain for public consumption as they are meant solely for testing purposes by me. If you read the PEP it would suggest that all modules in test are subject to the PEP's compatibility policy which is obviously absurd. -Brett

Problems with events in a numeric keyboard
by Martin Zugnoni 26 Aug '09

26 Aug '09

Hi! I'm trying to catch the triple zero (000) key from a numeric keyboard but, I found that it's the same id that the single zero. So, when I press the triple zero key once, I receive three events from the single zero key. I need to make a disctintion between these keys, and use them to different functionalities. How can I do?

No 2.4.7 release
by "Martin v. Löwis" 26 Aug '09

26 Aug '09

I once announced that I would be working on releasing 2.4.7 this month. However, since no patches have been committed to 2.4.6, there is little point in making a release. As 2.4 is nearing its end-of-life soon, there likely won't be any 2.4.7 release. Python 2.5 has seen only two patches since 2.5.4. However, since several months have been passed since that release, I'll be creating a 2.5.5 release candidate within a few days. Further security releases of Python 2.5 will be made until September 2011. Regards, Martin

Support for Encrypted Zip as python scripts
by Shashank Singh 26 Aug '09

26 Aug '09

There is an interesting suggestion (http://bugs.python.org/issue6749). to add support to run encrypted zip files as python scripts. No doubt this is a useful functionality to have but it would be great to have some comments on whether this can be(or even should be) feasibly added as an inbuilt support. -- Regards Shashank Singh Senior Undergraduate, Department of Computer Science and Engineering Indian Institute of Technology Bombay shashank.sunny.singh(a)gmail.com http://www.cse.iitb.ac.in/~shashanksingh

Re: [Python-Dev] Support for Encrypted Zip as python scripts
by Bugbee, Larry 25 Aug '09

25 Aug '09

I like the idea, but... Here is a quick list of things to think about and if some of this has already been mentioned, sorry. Speed: Encryption speed has been mentioned. For short scripts this may not be a problem, although algorithms implemented in C would be faster. Strength: Passwords are [very] weak, especially if of the 6-10 alphanumeric variety. True secret keys where all bit combinations are used is stronger. Entering passwords has been mentioned but I believe only passwords were assumed. It is better to not provide any encryption than to lure novices into believing they are secure when they are not. Algorithms: Be sure to choose good ones and allow for changing later. Key distribution: How to distribute secret keys beyond a small group of friends is problematic. In short it doesn't scale. Looking to public-private key pairs can be equally problematic. This can get you into encryption certs, but *how* you use them correctly differs from signing certs. More on this later if you want. ZIP: Look beyond just zip files. A scheme that works for any/all files in the distribution, not just ZIPs, would be better. (IIRC there have been problems with encrypted zips, but that was years ago. Those issues may have been fixed.) Short version: Doing this right is hard. Simply supporting a password based ZIP file is, in my opinion, not real protection. Gotta go. Later. Larry

Issue 1170: Unicode for ‘shlex’
by Ben Finney 22 Aug '09

22 Aug '09

Howdy all, What is the procedure for finding out why an issue hasn't progressed? I don't want to fill the bug database with such noise. In the case of <URL:http://bugs.python.org/issue1170> (“shlex have problems with parsing unicode”), the problem is apparently addressed by a patch, assigned to that issue since 2007-12-22. There is no indication in the report why it's not yet applied. I'd really like this fixed in the 2.x series if possible. -- \ “… whoever claims any right that he is unwilling to accord to | `\ his fellow-men is dishonest and infamous.” —Robert G. | _o__) Ingersoll, _The Liberty of Man, Woman and Child_, 1877 | Ben Finney
