Barry Warsaw dadace004b PyString_FromFormat() and PyString_FromFormatV(): Largely ripped from
PyErr_Format() these new C API methods can be used instead of
    sprintf()'s into hardcoded char* buffers.  This allows us to fix
    many situation where long package, module, or class names get
    truncated in reprs.

    PyString_FromFormat() is the varargs variety.
    PyString_FromFormatV() is the va_list variety

    Original PyErr_Format() code was modified to allow %p and %ld
    expansions.

    Many reprs were converted to this, checkins coming soo.  Not
    changed: complex_repr(), float_repr(), float_print(), float_str(),
    int_repr().  There may be other candidates not yet converted.

    Closes patch #454743.

Tim Peters e2c18e90da ceval, PyEval_MergeCompilerFlags: wasn't merging in the
CO_FUTURE_DIVISION flag.  Redid this to use Jeremy's PyCF_MASK #define
instead, so we dont have to remember to fiddle individual feature names
here again.

pythonrun.h:  Also #define a PyCF_MASK_OBSOLETE mask.  This isn't used
yet, but will be as part of the PEP 264 implementation (compile() mustn't
raise an error just because old code uses a flag name that's become
obsolete; a warning may be appropriate, but not an error; so compile() has
to know about obsolete flags too, but nobody is going to remember to
update compile() with individual obsolete flag names across releases either
-- i.e., this is the flip side of PyEval_MergeCompilerFlags's oversight).

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.

Fred Drake d55657bdf2 Added comments before recently added/assigned slots in the type object,
so the backward compatibility issues will be easier to understand.  I only
added comments indicating additions and assignments back to Python 2.0.

Jeremy Hylton 910d7d46dc Remove much dead code from ceval.c
The descr changes moved the dispatch for calling objects from
call_object() in ceval.c to PyObject_Call() in abstract.c.
call_object() and the many functions it used in ceval.c were no longer
used, but were not removed.

Rename meth_call() as PyCFunction_Call() so that it can be called by
the CALL_FUNCTION opcode in ceval.c.

Also, fix error message that referred to PyEval_EvalCodeEx() by its
old name eval_code2().  (I'll probably refer to it by its old name,
too.)

Jeremy Hylton 1abf610b15 Remove st_nested_scopes from struct symtable,
because nested scopes are always enabled.

(Accidentally checked in one small change along this path yesterday,
wreaking havoc in the Windows build.)

Jeremy Hylton fdd12f66bb Refactor future feature handling
Replace individual slots in PyFutureFeatures with a single bitmask
with one field per feature.  The flags for this bitmask are the same
as the flags used in the co_flags slot of a code object.

    XXX This means we waste several bits, because they are used
    for co_flags but have no meaning for future statements.  Don't
    think this is an issue.

Remove the NESTED_SCOPES_DEFAULT define and others.  Not sure what
they were for anyway.

Remove all the PyCF_xxx flags, but define PyCF_MASK in terms of the
CO_xxx flags that are relevant for this release.

Change definition of PyCompilerFlags so that cf_flags matches
co_flags.

Guido van Rossum 05ac6de2d5 Add PyDict_Merge(a, b, override):
PyDict_Merge(a, b, 1) is the same as PyDict_Update(a, b).
PyDict_Merge(a, b, 0) does something similar but leaves existing items
unchanged.
2001-08-10 20:28:28 +00:00
Guido van Rossum 9b9c972abe Add new flags for PyType_Ready(): READY to explicitly indicate the
type is ready, and READYING to indicate that it is busy with the type.

A recursive call is a fatal error.

Tim Peters 772747b3f1 SF patch #438013 Remove 2-byte Py_UCS2 assumptions
Removed all instances of Py_UCS2 from the codebase, and so also (I hope)
the last remaining reliance on the platform having an integral type
with exactly 16 bits.
PyUnicode_DecodeUTF16() and PyUnicode_EncodeUTF16() now read and write
one byte at a time.

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).

2001-07-31 18:05:33 +00:00
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 cecd9e0af3 va_list is defined in stdarg.h. 2001-07-31 14:23:52 +00:00
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.
2001-07-03 23:39:52 +00:00
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.
