I do not mean a rather faithful and accessible reconstruction such as Brett Cannons work but a radical re- design which starts with a domain model and does not end with Loaders, Importers and Finders which are actually services that pretend to be objects.

Writing to Console on mac OS X
by RGK March 31, 2009

March 31, 2009

I'm on mac os x 10.4.11 running python 2.5.2, and Django 1.0, but this is a python question. When doing django/mod_python stuff, I can write to the Apache error_log file with sys.stderr.write("SOMETHING I WANT TO KNOW") which had me wondering if there's not a means for a misc. python program to write to the Mac OS X console? That would be much nicer than having to open up the error log and inspect stuff, as then I could see debug info stream past on a console window. (This is console, as in the "console" run from /Applications/Utilities, not the bash "Terminal") Any help or suggestions appreciated. Thx. Ross.

Creating huge data in very less time.
by venutaurus539＠gmail.com March 31, 2009

March 31, 2009

Hello all, I've a requirement where I need to create around 1000 files under a given folder with each file size of around 1GB. The constraints here are each file should have random data and no two files should be unique even if I run the same script multiple times. Moreover the filenames should also be unique every time I run the script.One possibility is that we can use Unix time format for the file names with some extensions. Can this be done within few minutes of time. Is it possble only using threads or can be done in any other way. This has to be done in Windows. Please mail back for any queries you may have, Thank you, Venu Madhav.

create a log level for python logging module
by dj March 31, 2009

March 31, 2009

I am trying to create a log level called userinfo for the python logging. I read the source code and tried to register the level to the logging namespace with the following source: from logging import Logger # create the custom log level class userinfo(Logger): def userinfo(self, msg, *args, **kwargs): if self.isEnabledFor(WARNING): self._log(WARNING, msg, args, **kwargs) # Register log level in the logging.Logger namespace Logger.userinfo = userinfo Has I am sure you guessed, it did not work. If you know how this is done or know what I am doing work or can provide a link to example code (because I have not been able to locate any), I would greatly appreciate it. My sincere and heartfelt thanks in advance.

Printing Out Called Function Calls
by Victor Subervi March 31, 2009

March 31, 2009

Hi; Due to screwy problems at my server farm that they refuse to fix, I need to call lines that execute code from other files, like this: theContent += `tidBits[i][y][:-2]` but what that returns is this (as an example): tableTop(348,180) when I need it to execute the fn tableTop. What do? TIA, Victor

Cyclic GC rules for subtyped objects with tp_dictoffset
by BChess March 31, 2009

March 31, 2009

Hi, I'm writing a new PyTypeObject that is base type, supports cyclic GC, and has a tp_dictoffset. If my type is sub-typed by a python class, what exactly are the rules for how I'm supposed to treat my PyDict object with regards to cyclic GC? Do I still visit it in my traverse () function if I'm subtyped? Do I decrement the refcount upon dealloc? By the documentation, I'm assuming I should always be using _PyObject_GetDictPtr() to be accessing the dictionary, which I do. But visiting the dictionary in traverse() in the case it's subtyped results in a crash in weakrefobject.c. I'm using Python 2.5. Thanks for any help anyone has! Ben

Listing all python modules robustly
by Brian March 31, 2009

March 31, 2009

I've used the C api to write a method that can call any python module function. I would like to extend the interface to allow dynamically listing all python modules, and for a given module all functions, and for a given function all argument types and the return types if possible. Starting with the modules, I came up with this bit of code: from pkgutil import walk_packages; modules=[] modules = [modules.append(item[1]) for item in walk_packages()] I then took this to my various systems for testing. It works fine on OSX and one of my Ubuntu boxes, but two of the Ubuntu boxes fail, each with a different error message. The failure is due to python importing every single module and some of the modules failing. One example is the UniConverter package - towards the end of __init__.py it calls sys.exit(0) which kills the interpreter completely. I've spent a ton of time trying to rewrite walk_packages to be robust to failure, but so far without luck. Any advice is appreciated. /Brian
