mostly from SF patch #683257, but I had to change unlock_import() to
return an error value to avoid fatal error.

Should this be backported?  The patch requested this, but it's a new
feature.

folded; this will change in Python 2.4.  On a 32-bit machine, this
happens for 0x80000000 through 0xffffffff, and for octal constants in
the same value range.  No warning is issued if an explicit base is
given, *or* if the string contains a sign (since in those cases no
sign folding ever happens).

Volunteers wanted to fix it!)

"Unsigned" (i.e., positive-looking, but really negative) hex/oct
constants with a leading minus sign are once again properly negated.
The micro-optimization for negated numeric constants did the wrong
thing for such hex/oct constants.  The patch avoids the optimization
for all hex/oct constants.

This needs to be backported to Python 2.2!

Did a little cleanup of PyObject_IsInstance() too.

has drastically changed the structure, as the PEP241 names aren't
identifiers.

types -- Python types already inherited this.

* Modules/bz2module.c
  (BZ2FileObject): Now the structure includes a pointer to a file object,
   instead of "inheriting" one. Also, some members were copied from the
   PyFileObject structure to avoid dealing with the internals of that
   structure from outside fileobject.c.

  (Util_GetLine,Util_DropReadAhead,Util_ReadAhead,Util_ReadAheadGetLineSkip,
   BZ2File_write,BZ2File_writelines,BZ2File_init,BZ2File_dealloc,
   BZ2Comp_dealloc,BZ2Decomp_dealloc):
   	These functions were adapted to the change above.

  (BZ2File_seek,BZ2File_close): Use PyObject_CallMethod instead of
   getting the function attribute locally.

  (BZ2File_notsup): Removed, since it's not necessary anymore to overload
   truncate(), and readinto() with dummy functions.

  (BZ2File_methods): Added xreadlines() as an alias to BZ2File_getiter,
   and removed truncate() and readinto().

  (BZ2File_get_newlines,BZ2File_get_closed,BZ2File_get_mode,BZ2File_get_name,
   BZ2File_getset):
   	Implemented getters for "newlines", "mode", and "name".

  (BZ2File_members): Implemented "softspace" member.

  (BZ2File_init): Reworked to create a file instance instead of initializing
   itself as a file subclass. Also, pass "name" object untouched to the
   file constructor, and use PyObject_CallFunction instead of building the
   argument tuple locally.

  (BZ2File_Type): Set tp_new to PyType_GenericNew, tp_members to
   BZ2File_members, and tp_getset to BZ2File_getset.

  (initbz2): Do not set BZ2File_Type.tp_base nor BZ2File_Type.tp_new.

  Do not mention that BZ2File inherits from the file type.

descr_check(); it wasn't useful.  Change the type argument of the
various _get() methods to PyObject * because the call signature of
tp_descr_get doesn't guarantee its type.

select_select() didn't set an exception in the SELECT_USES_HEAP case when
malloc() returned NULL.

now, it was only called once, and its existence merely obfuscates the

- Fixed resizing of multi-column lists, somewhat.

when Python code calls a descriptor's __get__ method.  It should
translate None to NULL in both argument positions, and insist that at
least one of the argument positions is not NULL after this
transformation.
