oct and hex Py3k warnings
by Benjamin Peterson May 19, 2008

May 19, 2008

I know Guido has opposed adding Py3k warnings to oct and hex for "practical reasons," but I would like to make the case again. future_buitlins oct and hex will give you the correct Py3k behavior, but 2to3 can't convert old hex and oct usage to the new ones. That's why is would be helpful to warn about it and encourage people to import from future_builtins. -- Cheers, Benjamin Peterson "There's no place like 127.0.0.1."

Visual Studio 2008 compiler option EHsc ?
by Jim Kleckner May 19, 2008

May 19, 2008

In building a package with several platforms, I ran across the warning message below from Visual Studio 2008. Should we add the /EHsc option to the compile_options in distutils for MSVC? Or is it more complex than that...

Documentation for ability to execute zipfiles & directories
by Nick Coghlan May 19, 2008

May 19, 2008

A few months ago, 2.6 & 3.0 gained the ability to execute zipfiles and directories containing a __main__.py file (see [1] for details). The idea is that a whole application can be bundled into a zipfile containing a __main__.py module in its root directory, and then passed directly to the interpreter for execution, with the zipfile being inserted as the first entry on sys.path to allow easy access to the rest of the application code. It is inspired by Java's JAR option, but not … [View More]

Optimization of Python ASTs: How should we deal with constant values?
by Thomas Lee May 19, 2008

May 19, 2008

Hi all, I've been working on optimization of the AST, including the porting of the old bytecode-level optimizations to the AST level. A few questions have come up in the process of doing this, all of which are probably appropriate for discussion on this list. The code I'm referring to here can be found in the tlee-ast-optimize branch. Most of the relevant code is in Python/optimize.c and Python/peephole.c. Nearly all of the bytecode-level optimizations have been moved to the AST … [View More]

Possible problem that may be caused by Tkinter renaming
by Guilherme Polo May 18, 2008

May 18, 2008

Hello, I smell a problem caused by this line at tkinter/__init__.py: tkinter = _tkinter # b/w compat for export This was fine when tkinter was a Tkinter module, but I believe it would be better to rename this to something else. Given that python has a lot of users, I'm sure you will be able to find all sort of crazy things over the internet and one of them could be: import tkinter from tkinter import * something = tkinter._default_root Which is not that crazy at all, for some values of … [View More]

platform module testing
by Benjamin Peterson May 18, 2008

May 18, 2008

At the moment, the test for the platform module merely calls each function. I realize that this is a hard module to test well, but are there some assumptions we can make? For example, if sys.platform is 'java', can it be assumed that java_ver is going to return something which is not empty. When sys.platform is 'darwin' and the gestalt module is present, is it reasonable to require that a empty tuple not be returned? -- Cheers, Benjamin Peterson "There's no place like 127.0.0.1."

How best to handle the docs for a renamed module?
by Brett Cannon May 17, 2008

May 17, 2008

For the sake of argument, let's consider the Queue module. It is now named queue. For 2.6 I plan on having both Queue and queue listed in the index, with Queue deprecated with instructions to use the new name. But what to do about all the references. Should we leave them pointing at Queue to lessen confusion for people who read about some module on some other site that isn't using the new name, or update everything in 2.6 to use the new name? -Brett

lib2to3, need some light on the imports fixer
by Guilherme Polo May 17, 2008

May 17, 2008

Hello, Would someone tell me how can I add a new entry in the MAPPING dict in the lib2to3/fixes/fix_imports.py that does the following: "import A" gets fixed as "import C.D as A" Right now it is fixing by doing "import C.D" and changing several other lines in the code to use this new "C.D" name. I wanted to avoid these changes if possible. Regards, -- -- Guilherme H. Polo Goncalves
