Tim Peters 8a267b62cc Remove 6-year old hack to worm around a bug in "NextSpec/Sparc 3.3
pre-release limits.h".

Jack Jansen 94bebc0381 Split macglue.c into two: a new mactoolboxglue.c (in ./Python)
with functionality needed for both unix-Python and MacPython and a
new smaller ./Mac/Python/macglue.c which contains MacPython stuff only.

pymactoolbox.h has moved to ./Include from ./Mac/Include and now also
contains the relevant stuff from macglue.h.

The net effect of this is that the ./Mac subdirectory is not needed
anymore for building the unix-Python core on MacOSX (it is needed
for building the extension modules).

Martin v. Löwis f9836ba4fe Put conditional S_ISDIR definition(s) into pyport.h. 2001-08-08 10:28:06 +00:00
Guido van Rossum 4668b000a1 Implement PEP 238 in its (almost) full glory.
This introduces:

- A new operator // that means floor division (the kind of division
  where 1/2 is 0).

- The "future division" statement ("from __future__ import division)
  which changes the meaning of the / operator to implement "true
  division" (where 1/2 is 0.5).

- New overloadable operators __truediv__ and __floordiv__.

- New slots in the PyNumberMethods struct for true and floor division,
  new abstract APIs for them, new opcodes, and so on.

I emphasize that without the future division statement, the semantics
of / will remain unchanged until Python 3.0.

Not yet implemented are warnings (default off) when / is used with int
or long arguments.

This has been on display since 7/31 as SF patch #443474.

Flames to /dev/null.

Guido van Rossum 528b7eb0b0 - Rename PyType_InitDict() to PyType_Ready().
- Add an explicit call to PyType_Ready(&PyList_Type) to pythonrun.c
  (just for the heck of it, really -- we should either explicitly
  ready all types, or none).

Marc-André Lemburg b5ac6f62c7 As discussed on python-dev: this patch adds name mangling to
assure that extensions and interpreters using the Unicode APIs
were compiled using the same Unicode width.

Marc-André Lemburg e5006ebc9d This patch turns the Python API mismatch notice into a standard
Python warning which can be catched by means of the Python warning
framework.

It also adds two new APIs which hopefully make it easier for Python
to switch to buffer overflow safe [v]snprintf() APIs for error
reporting et al. The two new APIs are PyOS_snprintf() and
PyOS_vsnprintf() and work just like the standard ones in many
C libs. On platforms which have snprintf(), the native APIs are used,
on all other an emulation with snprintf() tries to do its best.

Jeremy Hylton 3ce45389bd Add _PyUnicode_AsDefaultEncodedString to unicodeobject.h.
And remove all the extern decls in the middle of .c files.
Apparently, it was excluded from the header file because it is
intended for internal use by the interpreter.  It's still intended for
internal use and documented as such in the header file.

Tim Peters fe2127d3cb Ugly. A pile of new xxxFlags() functions, to communicate to the parser
that 'yield' is a keyword.  This doesn't help test_generators at all!  I
don't know why not.  These things do work now (and didn't before this
patch):

1. "from __future__ import generators" now works in a native shell.

2. Similarly "python -i xxx.py" now has generators enabled in the
   shell if xxx.py had them enabled.

3. This program (which was my doctest proxy) works fine:

from __future__ import generators

source = """\
def f():
    yield 1
"""

exec compile(source, "", "single") in globals()
print type(f())
2001-07-16 05:37:24 +00:00
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.
2001-07-16 02:29:45 +00:00
Guido van Rossum b09f7ed623 Preliminary support for "from __future__ import generators" to enable
the yield statement.  I figure we have to have this in before I can
release 2.2a1 on Wednesday.

Note: test_generators is currently broken, I'm counting on Tim to fix
this.

Tim Peters 0d5dd68692 Python.h: Don't attempt to redefine NDEBUG if it's already defined.
Others:  Remove redundant includes of assert.h.
2001-07-15 18:38:47 +00:00
Guido van Rossum b2c075bec4 Define NDEBUG when Py_DEBUG undefined, to disable the assert macro. 2001-07-15 16:58:05 +00:00
Guido van Rossum aa31429854 Enable nested scopes by default.
Although this is a one-character change, more work needs to be done:
the compiler can get rid of a lot of non-nested-scopes code, the
documentation needs to be updated, the future statement can be
simplified, etc.

But this change enables the nested scope semantics everywhere, and
that's the important part -- we can now test code for compatibility
with nested scopes by default.

Thomas Wouters efafcea280 Re-add 'advanced' xrange features, adding DeprecationWarnings as discussed
on python-dev. The features will still vanish, however, just one release
later.
2001-07-09 12:30:54 +00:00
Guido van Rossum 3f56166b1a Rip out the fancy behaviors of xrange that nobody uses: repeat, slice,
contains, tolist(), and the start/stop/step attributes.  This includes
removing the 4th ('repeat') argument to PyRange_New().
2001-07-05 13:27:48 +00:00
Fred Drake 9e3ad78444 This change adjusts the profiling/tracing support so that the common
path (with no profile/trace function) through eval_code2() and
eval_frame() avoids several checks.

In the common cases of calls, returns, and exception propogation,
eval_code2() and eval_frame() used to test two values in the
thread-state: the profiling function and the tracing function.  With
this change, a flag is set in the thread-state if either of these is
active, allowing a single check to suffice when both are NULL.  This
also simplifies the code needed when either function is in use but is
already active (to avoid profiling/tracing the profiler/tracer); the
flag is set to 0 when the profile/trace code is entered, allowing the
same check to suffice for "already in the tracer" for call/return/
exception events.

Fredrik Lundh 72b068566a removed "register const" from scalar arguments to the unicode
predicates
2001-06-27 22:08:26 +00:00
Fred Drake 55fb6e0371 Revise the interface to the profiling and tracing support for the
Python interpreter.

This change adds two new C-level APIs:  PyEval_SetProfile() and
PyEval_SetTrace().  These can be used to install profile and trace
functions implemented in C, which can operate at much higher speeds
than Python-based functions.  The overhead for calling a C-based
profile function is a very small fraction of a percent of the overhead
involved in calling a Python-based function.

The machinery required to call a Python-based profile or trace
function been moved to sysmodule.c, where sys.setprofile() and
sys.setprofile() simply become users of the new interface.

Fredrik Lundh 8f4558583f use Py_UNICODE_WIDE instead of USE_UCS4_STORAGE and Py_UNICODE_SIZE
tests.

Martin v. Löwis ce9b5a55e1 Encode surrogates in UTF-8 even for a wide Py_UNICODE.
Implement sys.maxunicode.
Explicitly wrap around upper/lower computations for wide Py_UNICODE.
When decoding large characters with UTF-8, represent expected test
results using the \U notation.

Fredrik Lundh 9b14ab367a Make Unicode work a bit better on Windows... 2001-06-26 22:59:49 +00:00
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.
2001-06-26 22:22:37 +00:00
Fredrik Lundh 1294ad0c59 experimental UCS-4 support: added USE_UCS4_STORAGE define to
unicodeobject.h, which forces sizeof(Py_UNICODE) == sizeof(Py_UCS4).
(this may be good enough for platforms that doesn't have a 16-bit
type.  the UTF-16 codecs don't work, though)
2001-06-26 17:17:07 +00:00
Tim Peters 8c96369513 PyFrameObject: rename f_stackbottom to f_stacktop, since it points to
the next free valuestack slot, not to the base (in America, stacks push
and pop at the top -- they mutate at the bottom in Australia <winK>).
eval_frame():  assert that f_stacktop isn't NULL upon entry.
frame_delloc():  avoid ordered pointer comparisons involving f_stacktop
when f_stacktop is NULL.
2001-06-23 05:26:56 +00:00
Guido van Rossum 14e1871607 Somehow, under certain circumstances, config.h and rename1.h would pop back up.
Try to see if 'cvs delete' fixes this.

Tim Peters 5ca576ed0a Merging the gen-branch into the main line, at Guido's direction. Yay!
Bugfix candidate in inspect.py:  it was referencing "self" outside of
a method.

Tim Peters a7259597f1 SF bug 433228: repr(list) woes when len(list) big.
Gave Python linear-time repr() implementations for dicts, lists, strings.
This means, e.g., that repr(range(50000)) is no longer 50x slower than
pprint.pprint() in 2.2 <wink>.

I don't consider this a bugfix candidate, as it's a performance boost.

Added _PyString_Join() to the internal string API.  If we want that in the
public API, fine, but then it requires runtime error checks instead of
asserts.
2001-06-16 05:11:17 +00:00
Tim Peters 2a9b367385 Two new private longobject API functions,
_PyLong_FromByteArray
    _PyLong_AsByteArray
Untested and probably buggy -- they compile OK, but nothing calls them
yet.  Will soon be called by the struct module, to implement x-platform
'q' and 'Q'.
If other people have uses for them, we could move them into the public API.
See longobject.h for usage details.
2001-06-11 21:23:58 +00:00
Martin v. Löwis eefa964932 Cast the result of xxxPyCObject_Import to PycStringIO_CAPI*.

Martin v. Löwis 3d10b34b9c Wrap with extern "C". Fixes bug #428419.
Also protect against multiple inclusion.

Martin v. Löwis cd35306a25 Patch #424335: Implement string_richcompare, remove string_compare.
Use new _PyString_Eq in lookdict_string.
2001-05-24 16:56:35 +00:00
Marc-André Lemburg 489b56e044 This patch changes the behaviour of the UTF-16 codec family. Only the
UTF-16 codec will now interpret and remove a *leading* BOM mark. Sub-
sequent BOM characters are no longer interpreted and removed.
UTF-16-LE and -BE pass through all BOM mark characters.

These changes should get the UTF-16 codec more in line with what
the Unicode FAQ recommends w/r to BOM marks.
2001-05-21 20:30:15 +00:00
Marc-André Lemburg 2d9204199f This patch changes the way the string .encode() method works slightly
and introduces a new method .decode().

The major change is that strg.encode() will no longer try to convert
Unicode returns from the codec into a string, but instead pass along
the Unicode object as-is. The same is now true for all other codec
return types. The underlying C APIs were changed accordingly.

Note that even though this does have the potential of breaking
existing code, the chances are low since conversion from Unicode
previously took place using the default encoding which is normally
set to ASCII rendering this auto-conversion mechanism useless for
most Unicode encodings.

The good news is that you can now use .encode() and .decode() with
much greater ease and that the door was opened for better accessibility
of the builtin codecs.

As demonstration of the new feature, the patch includes a few new
codecs which allow string to string encoding and decoding (rot13,
hex, zip, uu, base64).
