Neil Schemenauer 927a57fbeb Ensure negative offsets cannot be passed to buffer(). When composing
buffers, compute the new buffer size based on the old buffer size.
Fixes SF bug #1034242.

Neil Schemenauer fb6ba07d9c Fix buffer offset calculation (need to compute it before changing
'base').  Fixes SF bug #1033720.  Move offset sanity checking to
buffer_from_memory().

Guido van Rossum e3a8e7ed1d Call me anal, but there was a particular phrase that was speading to
comments everywhere that bugged me: /* Foo is inlined */ instead of
/* Inline Foo */.  Somehow the "is inlined" phrase always confused me
for half a second (thinking, "No it isn't" until I added the missing
"here").  The new phrase is hopefully unambiguous.

Raymond Hettinger 5a04aec384 Fix SF bug 546434 -- buffer slice type inconsistent. 2002-06-25 00:25:30 +00:00
Guido van Rossum bea18ccde6 SF patch 568629 by Oren Tirosh: types made callable.
These built-in functions are replaced by their (now callable) type:

    slice()
    buffer()

and these types can also be called (but have no built-in named
function named after them)

    classobj (type name used to be "class")
    code
    function
    instance
    instancemethod (type name used to be "instance method")

The module "new" has been replaced with a small backward compatibility
placeholder in Python.

A large portion of the patch simply removes the new module from
various platform-specific build recipes.  The following binary Mac
project files still have references to it:

    Mac/Build/PythonCore.mcp
    Mac/Build/PythonStandSmall.mcp
    Mac/Build/PythonStandalone.mcp

[I've tweaked the code layout and the doc strings here and there, and
added a comment to types.py about StringTypes vs. basestring.  --Guido]

Fred Drake a44d353e2b Trent Mick <trentm@activestate.com>:
The common technique for printing out a pointer has been to cast to a long
and use the "%lx" printf modifier. This is incorrect on Win64 where casting
to a long truncates the pointer. The "%p" formatter should be used instead.

The problem as stated by Tim:
> Unfortunately, the C committee refused to define what %p conversion "looks
> like" -- they explicitly allowed it to be implementation-defined. Older
> versions of Microsoft C even stuck a colon in the middle of the address (in
> the days of segment+offset addressing)!

The result is that the hex value of a pointer will maybe/maybe not have a 0x
prepended to it.


Notes on the patch:

There are two main classes of changes:
- in the various repr() functions that print out pointers
- debugging printf's in the various thread_*.h files (these are why the
patch is large)


Closes SourceForge patch #100505.

Guido van Rossum b18618dab7 Vladimir Marangozov's long-awaited malloc restructuring.
For more comments, read the patches@python.org archives.
For documentation read the comments in mymalloc.h and objimpl.h.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode.  I'm also holding back on his
change to main.c, which seems unnecessary to me.)

Fred Drake 4574f23115 PyBuffer_New(): Raise ValueError if size is negative (the other
constructors didn't miss this).
