* 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.
* Doc/lib/libbz2.tex
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.
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.
object is not a real str or unicode but an instance
of a subclass, construct the output via looping
over __getitem__. This guarantees that the result
is the same for function==None and function==lambda x:x
This doesn't happen for tuples, because filtertuple()
uses PyTuple_GetItem().
(This was discussed on SF bug #665835).
* Removed the ifilter flag wart by splitting it into two simpler functions.
* Fixed comment tabbing in C code.
* Factored module start-up code into a loop.
Documentation:
* Re-wrote introduction.
* Addede examples for quantifiers.
* Simplified python equivalent for islice().
* Documented split of ifilter().
Sets.py:
* Replace old ifilter() usage with new.
