[CC to python-dev] The windist.exe version shipped with current python releasese is outdated and does not have any license information about windist included.

I cannot find anything about the licensing.

[Debian only: The UPX license itself is discussed at http://lists.debian.org/debian-legal/2001/01/msg00025.html upx-nrv is currently in section non-free/utils, so it's better not to distribute it in the Debian package. ]

I'm on windows and am quite attached to coding and running inside SciTE. I think I could knock up a script to do the right thing and configure SciTE to run it rather than python. However since I sometimes run from the command line and my colleagues use different editors that's a whole other can of worms. > 2.

I suppose I could, but adding a bit of boilerplate to the top of every source file to support something that should be completely orthogonal to the the language (using source control branches) seems a bit hacky- workaround-tastic even compared to my current solution (a post-it saying 'check PYTHONPATH' in big letters stuck to my monitor) Anyway, enough discussion of my situation, which is probably more suited to python-list. My real question is: Is there any desire to address this problem in some future python? When I see 2 python-dev'ers say "PYTHONPATH isn't up to it, here's what I do" I smell something that should be fixed once rather that worked around everywhere. My initial idea was something along the lines of: When a module is imported, its import search path includes everything it does now PLUS the directory that is the top of the module's enclosing package structure. That way you wouldn't have to add entries to PYTHONPATH just so that modules could import (absolutely) from their own package. What do you think? Possible? Sensible? Any other ideas? Rich

cmp(x,x)
by Jewett, Jim J 18 May '04

18 May '04

Armin Rigo: say x has a method __cmp__() that always returns -1. >>> x == x # x.__cmp__() is called False >>> x < x # x.__cmp__() is called True >>> cmp(x,x) # x.__cmp__() is NOT called 0 >>> [x] == [x] # x.__cmp__() is NOT called True Note that the last (and only the last) is a change from 2.3 In 2.3, the (identity does not imply equality) trait rolls up to containers. >>> l=[x] >>> l == l False The only way to explain the semantic is that the expression 'x == x' always call the special methods, but built-in functions are allowed to assume that any object compares equal to itself. Note that "allowed" is as strong as you can get; is implies ==, but does not (currently) imply <= or preclude <. Should any of this be documented? I think so; it is a problem only for pathological cases, but who would bother to look up rich comparison in the first place unless they were considering at least borderline strangeness. An alternative behavior would have been to leave PyObject_RichCompareBool() alone and only insert the short-cut on specific object types' comparison methods I think it is reasonable for the default to be that identity implies equality. Either an explicitly defined __cmp__ should always be called, or the notes should say that containers can treat identity as good enough. This is sane as long as no code considers 'nan' as a singleton, or tries to reuse 'nan' objects for different 'nan' values. Note that float('nan') raises on ValueError on at least the default windows 2.3 build; if a NaN is hard to get, I would expect it to be reused. -jJ

Guido said: > The same arguments could > prove that Java's bytecode verification is "impossible", but > nevertheless it's done. But I belive Armin's argument that it equals the halting problem is incorrect. The net stack effect of bytecode can be verified regardless of the algorithm. If it is seen that two bytecodes produce an element on the stack and one bytecode consumes two, then the net effect is zero. As Jeremy pointed out, iterations (of well formed code) have no net effect. Although Armin's example could certainly fail due to exhausting the stack of return frames (which is a runtime issue), or memory, or anything else, no well formed bytecode can exhaust the bytecode stack. The way to know if it's well formed is to verify it using something like a control flow analysis similar to the way the Java ASM bytecode generation API does it. The secondary benefit of this is that you are assured at runtime that the stack size the compiler computes for the bytecode is genuine. -Michel

I'm working on a rough draft now. Initially I would like to start small and easy: a verifier written in python that provides a single function along the lines of the code provided by Phillip Eby that accepts the same arguments as dis(), a class, method, function, or code object. It throws an exception and explanation for invalid bytecode and it will be up to programmers to call this method explicitly and choose to execute the code object or not. This will probably cover almost all uses. > Python should be easier, in large part because you have to give up sooner. > > Checks for type correctness in the PVM are done at runtime instead.

I think it's likely that both run-time check elimination and segfault plugging can come out ot this. I'm not sure if it's possible for us to know what they all are up front, so I think a good requirement for a verification package will be a way to register new or project-specific verifications. do you think there is a risk of exploitation? for example, STORE_FAST, which does a direct set into PyObject **fastlocals, could be used to overwrite beyond the bounds of the array. Can this or a stack over/underflow be used to execute arbitrary machine code? > or > check that C-level indexing into the co_consts vector is in bounds. > Well, > in the latter case, that is checked (at runtime, on every co_consts access) > in a debug build, but not in a release build. I've investigated that a bit, and STORE_CONST and LOAD_CONST use GETITEM, which uses PyTuple_GetItem, which does a bounds check at run time even in a production build. I think. LOAD_FAST and STORE_FAST seem to do no runtime bounds check. -Michel

Python-Dev] Re: __str__ does not default to __repr__ if a base classhas __str__
by alloydflanagan＠comcast.net 17 May '04

FWIW, I think the current behavior is correct. If a __str__() method exists, it exists; we shouldn't treat an inherited method differently from one defined directly in the class. So I would be very surprised if the inherited __str__() wasn't used.

__str__ does not default to __repr__ if a base class has __str__
by Edward C. Jones 17 May '04

# In the code below, "a.__str__()" does not default to "a.__repr__() as # might be expected. It finds the "__str__" in the base class X. The # Reference Manual, section 3.3.1, says: # If a class defines __repr__() but not __str__(), then __repr__() is # also used when an 'informal' string representation of instances of # that class is required. # If the reader is in lawyer mode, the documentation is correct. # Is the current behavior what was intended? What should the behavior be? class X(object): def __str__(self): return 'str for X' def __repr__(self): return 'repr for X' class A(X): def __repr__(self): return 'repr for A' # __str__ = __repr__ x = X() a = A() print x.__str__() print x.__repr__() print a.__str__() print a.__repr__()

Python 2.3.4, release candidate 1 - BUG FIX
by Skip Montanaro 17 May '04

17 May '04

(Rerouting to python-dev...) Jeff> When a tar, gzipped tar, or bzip2'd tar contains a .spec file, you're Jeff> supposed to be able to build it into a binary RPM with Jeff> rpmbuild -ta <tarball> Jeff> Unfortunately, with the spec file in this tarball, I get an error: Jeff> $ rpmbuild -ta Python-2.3.4c1.tar.bz2 Jeff> error: %changelog not in descending chronological order I checked in the "obvious correct fix" to the spec file on CVS HEAD. I can't test it though, not having convenient access to a RedHat-ish system these days. I'll leave it for Anthony or one of the other 2.3.4 release folks to backport it for the 2.3.4 release since that branch is closed. (The first date should have a year of 2004.) Skip
