The patch is clean. Problems like no two people on python-dev agreeing on how exactly the feature should be implemented. Problems like whether this goes way beyond the philosophical underpinnings of bin/oct/hex. Problems like what to do about other types that might want to overload hex/oct/bin. See Kevin Jacobs' response. >> This API appears to be >> purely for educational purposes; why not implement something in pure >> Python using the struct module that reveals the lay-out of the >> floating-point value? > > This is not the internal floating point layout.

Possibly, but it is only readable by a Python expression parser. For all practical purposes "%.17g" % x works just as well. And this bypasses the question "why overload this functionality on bin/hex/oct rather than adding e.g. a new function to math or a new method to float." >> (There are also several things wrong with the specific patch, apart >> from its lack of docs; #1 is the introduction of an externaly visible >> symbol that doesn't start with _Py.) > > Will change the global symbol to _Py. I already added docs to the patch. > Did you see the one that was uploaded a few hours ago (float6.diff)? I don't care about the details of the patch until we have agreement about which form the feature should take. We don't have that agreement yet. I mentioned the flaws in the patch to point out that it was apparently a rush job. > I re-opened the discussion at your behest. [...] I'm very glad you're giving the discussion a second chance. Please give it a few days at least. My expectation is that the outcome will be not to overload bin/hex/oct but to add a custom function to math or a custom method to float, whose output can be further massaged to create the platform-independent representation you're after. (I doubt that it's worth changing pickle or marshal though, they are doing fine with their respective current approaches.) -- --Guido van Rossum (home page: http://www.python.org/~guido/)

problems compiling ctypes
by Jeremy Link July 3, 2008

July 3, 2008

I've grabbed the latest libffi that contains support for the ARM processor. I then enable FFI_CLOSURES in the arm/ffi.c file. When I do this, I get compilation errors that it is missing ffi_prep_closure. Is ffi.c up to date for supporting the ARM platform? Not sure if there is a simple configuration change in one of the files that will fix *everything* or if ffi.c just doesn't support ARM yet and so it needs be developed/revamped. Thanks for any help.

Can someone check my lib2to3 change for fix_imports?
by Brett Cannon July 2, 2008

July 2, 2008

I just committed r64651 which is my attempt to add support to fix_imports so that modules that have been split up in 3.0 can be properly fixed. 2to3's test suite passes and all, but I am not sure if I botched it somehow since I did the change slightly blind. Can someone just do a quick check to make sure I did it properly? Also, what order should renames be declared to give priority to certain renames (e.g., urllib should probably be renamed to urllib.requeste over urllib.error when not used in a ``from ... import`` statement). -Brett

Who wants to work with Klocwork?
by Guido van Rossum July 2, 2008

July 2, 2008

I've got an offer from Klocwork (a static source code analysis company, www.klocwork.com) to give some developers free access to their findings from running their bug-finding software over Python source code. I don't have the bandwidth to deal with this myself, but I think it would be valuable if we could get some folks to look at their findings. We have a similar relationship with one of Klocwork's competitors. In my experience, each vendor's tool has a different strength, and it is likely that each will find some important bugs that the other didn't flag. So IMO it's useful to do this with each vendor that offers... -- --Guido van Rossum (home page: http://www.python.org/~guido/)

Review needed: proposed fix for 2.6 __hash__ incompatibility (issue 2235)
by Nick Coghlan July 2, 2008

July 2, 2008

I've posted a possible fix for the __hash__ backwards incompatibilities described in issue 2235 [1]. The patch uses a model similar to that used in Py3k (using None is indicate "don't inherit __hash__"), but extends it to allowing Py_None to be explicitly stored in the tp_hash slot. The major downside is that we suffer the cost of an extra pointer comparison on every call to PyObject_Hash, but I wasn't able to come up with another solution that preserved backwards compatibility while still allowing collections.Hashable to function correctly. The patch involves a few changes to fairly deep components in typeobject.c though, so I'd like at least some kind of sanity check before I commit it. Cheers, Nick.

[issue3214] Suggest change to glossary explanation: "Duck Typing"
by Paddy 3118 July 2, 2008

July 2, 2008

Hi, I'd like extra opinions on this issue please: http://bugs.python.org/issue3214 It's about changing the definition of Duck typing to remove hasattr and leave just EAFP in the enablers - more detail is in the issue log. Thanks, Paddy.

py3k branch still using -fno-strict-aliasing
by İsmail Dönmez July 2, 2008

July 2, 2008

Hi, I remember discussing this before and coming to conclusion that -fno-strict-aliasing would be removed from py3k CFLAGS. But as of now its still used. I tested with gcc 4.3.1 on Linux x86_64 and there is no strict aliasing warning when this flag is removed. Also make testall passes. Is there any reason to keep this flag? If not see the attached patch. Regards, ismail -- Programmer Excuses number 45: I do object-oriented programming - if the customer objects, I do more programming.
