Tim Peters 742dfd6f17 Get rid of builtin_open() entirely (the C code and docstring, not the
builtin function); Guido pointed out that it could be just another
name in the __builtin__ dict for the file constructor now.

Tim Peters 4b7625ee83 _PyBuiltin_Init(): For clarity, macroize this purely repetitive code. 2001-09-13 21:37:17 +00:00
Tim Peters 59c9a645e2 SF bug [#460467] file objects should be subclassable.
Preliminary support.  What's here works, but needs fine-tuning.

Guido van Rossum 8bce4acb17 Rename 'getset' to 'property'. 2001-09-06 21:56:42 +00:00
Guido van Rossum b3a639ed7d builtin_execfile(): initialize another local that the GCC on leroy
found it necessary to warn about.

Tim Peters 7eea37e831 At Guido's suggestion, here's a new C API function, PyObject_Dir(), like
__builtin__.dir().  Moved the guts from bltinmodule.c to object.c.
2001-09-04 22:08:56 +00:00
Tim Peters 37a309db70 builtin_dir(): Treat classic classes like types. Use PyDict_Keys instead
of PyMapping_Keys because we know we have a real dict.  Tolerate that
objects may have an attr named "__dict__" that's not a dict (Py_None
popped up during testing).

test_descr.py, test_dir():  Test the new classic-class behavior; beef up
the new-style class test similarly.

test_pyclbr.py, checkModule():  dir(C) is no longer a synonym for
C.__dict__.keys() when C is a classic class (looks like the same thing
that burned distutils! -- should it be *made* a synoym again?  Then it
would be inconsistent with new-style class behavior.).
2001-09-04 01:20:04 +00:00
Tim Peters 5d2b77cf31 Make dir() wordier (see the new docstring). The new behavior is a mixed
bag.  It's clearly wrong for classic classes, at heart because a classic
class doesn't have a __class__ attribute, and I'm unclear on whether
that's feature or bug.  I'll repair this once I find out (in the
meantime, dir() applied to classic classes won't find the base classes,
while dir() applied to a classic-class instance *will* find the base
classes but not *their* base classes).

Please give the new dir() a try and see whether you love it or hate it.
The new dir([]) behavior is something I could come to love.  Here's
something to hate:

>>> class C:
...     pass
...
>>> c = C()
>>> dir(c)
['__doc__', '__module__']
>>>

The idea that an instance has a __doc__ attribute is jarring (of course
it's really c.__class__.__doc__ == C.__doc__; likewise for __module__).

OTOH, the code already has too many special cases, and dir(x) doesn't
have a compelling or clear purpose when x isn't a module.

Guido van Rossum 29a62dd6eb Add new built-in type 'getset' (PyGetSet_Type).
This implements the 'getset' class from test_binop.py.

Tim Peters 9fa96bed6f Fix for bug [#452230] future division isn't propagated.
builtin_eval wasn't merging in the compiler flags from the current frame;
I suppose we never noticed this before because future division is the
first future-feature that can affect expressions (nested_scopes and
generators had only statement-level effects).

Martin v. Löwis 339d0f720e Patch #445762: Support --disable-unicode
- Do not compile unicodeobject, unicodectype, and unicodedata if Unicode is disabled
- check for Py_USING_UNICODE in all places that use Unicode functions
- disables unicode literals, and the builtin functions
- add the types.StringTypes list
- remove Unicode literals from most tests.

Jeremy Hylton 0eb1115f44 Fix for SF byg [ #420304 ] getattr function w/ default
Fix suggested by Michael Hudson: Raise TypeError if attribute name
passed to getattr() is not a string or Unicode.  There is some
unfortunate duplication of code between builtin_getattr() and
PyObject_GetAttr(), but it appears to be unavoidable.

Marc-André Lemburg ae21df59c3 Undoing the UCS-4 patch addition which caused unichr() to return
surrogates for Unicode code points outside range(0x10000) on narrow
Python builds.

Tim Peters 5ba5866281 Part way to allowing "from __future__ import generators" to communicate
that info to code dynamically compiled *by* code compiled with generators
enabled.  Doesn't yet work because there's still no way to tell the parser
that "yield" is OK (unlike nested_scopes, the parser has its fingers in
this too).
Replaced PyEval_GetNestedScopes by a more-general
PyEval_MergeCompilerFlags.  Perhaps I should not have?  I doubted it was
*intended* to be part of the public API, so just did.

2001-06-27 18:59:43 +00:00
Guido van Rossum 236d8b7974 Cosmetic changes to MvL's change to unichr():
- the correct range for the error message is range(0x110000);

- put the 4-byte Unicode-size code inside the same else branch as the
  2-byte code, rather generating unreachable code in the 2-byte case.

- Don't hide the 'else' behine the '}'.

(I would prefer that in 4-byte mode, any value should be accepted, but
reasonable people can argue about that, so I'll put that off.)

Martin v. Löwis 0ba70cc3c8 Support using UCS-4 as the Py_UNICODE type:
Add configure option --enable-unicode.
Add config.h macros Py_USING_UNICODE, PY_UNICODE_TYPE, Py_UNICODE_SIZE,
                    SIZEOF_WCHAR_T.
Define Py_UCS2.
Encode and decode large UTF-8 characters into single Py_UNICODE values
for wide Unicode types; likewise for UTF-16.
Remove test whether sizeof Py_UNICODE is two.

Tim Peters 8572b4fedf Generalize zip() to work with iterators.
NEEDS DOC CHANGES.
More AttributeErrors transmuted into TypeErrors, in test_b2.py, and,
again, this strikes me as a good thing.
This checkin completes the iterator generalization work that obviously
needed to be done.  Can anyone think of others that should be changed?

Tim Peters f4848dac41 Make PyIter_Next() a little smarter (wrt its knowledge of iterator

2001-05-04 04:39:21 +00:00
Tim Peters 4e9afdca39 Generalize map() to work with iterators.
NEEDS DOC CHANGES.
Possibly contentious:  The first time s.next() yields StopIteration (for
a given map argument s) is the last time map() *tries* s.next().  That
is, if other sequence args are longer, s will never again contribute
anything but None values to the result, even if trying s.next() again
could yield another result.  This is the same behavior map() used to have
wrt IndexError, so it's the only way to be wholly backward-compatible.
I'm not a fan of letting StopIteration mean "try again later" anyway.

Tim Peters 748b8bbe02 Fix buglet reported on c.l.py: map(fnc, file.xreadlines()) blows up.
Also a 2.1 bugfix candidate (am I supposed to do something with those?).
Took away map()'s insistence that sequences support __len__, and cleaned
up the convoluted code that made it *look* like it really cared about
__len__ (in fact the old ->len field was only *used* as a flag bit, as
the main loop only looked at its sign bit, setting the field to -1 when
IndexError got raised; renamed the field to ->saw_IndexError instead).

Guido van Rossum 59d1d2b434 Iterators phase 1. This comprises:
new slot tp_iter in type object, plus new flag Py_TPFLAGS_HAVE_ITER
new C API PyObject_GetIter(), calls tp_iter
new builtin iter(), with two forms: iter(obj), and iter(function, sentinel)
new internal object types iterobject and calliterobject
new exception StopIteration
new opcodes for "for" loops, GET_ITER and FOR_ITER (also supported by dis.py)
new magic number for .pyc files
new special method for instances: __iter__() returns an iterator
iteration over dictionaries: "for x in dict" iterates over the keys
iteration over files: "for x in file" iterates over lines

TODO:

documentation
test suite
decide whether to use a different way to spell iter(function, sentinal)
decide whether "for key in dict" is a good idea
use iterators in map/filter/reduce, min/max, and elsewhere (in/not in?)
speed tuning (make next() a slot tp_next???)

Tim Peters 388ed08cbf SF patch #413552 - Premature decref on object
Jeffery Collins pointed out that filterstring decrefs a character object
before it's done using it.  This works by accident today because another
module always happens to have an active reference too at the time.  The
accident doesn't work after his Pippy modifications, and since it *is*
an accident even in the mainline Python, it should work by design there too.
The patch accomplishes that.

Jeremy Hylton bc32024769 Extend support for from __future__ import nested_scopes
If a module has a future statement enabling nested scopes, they are
also enable for the exec statement and the functions compile() and
execfile() if they occur in the module.

If Python is run with the -i option, which enters interactive mode
after executing a script, and the script it runs enables nested
scopes, they are also enabled in interactive mode.

XXX The use of -i with -c "from __future__ import nested_scopes" is
not supported.  What's the point?

To support these changes, many function variants have been added to
pythonrun.c.  All the variants names end with Flags and they take an
extra PyCompilerFlags * argument.  It is possible that this complexity
will be eliminated in a future version of the interpreter in which
nested scopes are not optional.

Guido van Rossum 8dabbf149e Fix for the bug in complex() just reported by Ping. 2001-01-19 02:11:59 +00:00
Marc-André Lemburg ad7c98e264 This patch adds a new builtin unistr() which behaves like str()
except that it always returns Unicode objects.

A new C API PyObject_Unicode() is also provided.

This closes patch #101664.
