Guido van Rossum e5c691abe3 - The extended type structure used for heap types (new-style
classes defined by Python code using a class statement) is now
  exported from object.h as PyHeapTypeObject.  (SF patch #696193.)

Neal Norwitz 1930949a8a Fix SF bug #697256, PyMarshal_WriteShortToFile() documented, but not implemented
Remove prototype and doc.  Backport candidate.

Jack Jansen d00c13a9be Moved the Apple workaround for the guard define for wchar_t out of
the #ifdef HAVE_NCURSES_H: the same problem exists on OSX 10.1 with
a fink-installed curses (which uses curses.h as the include file name).

Guido van Rossum 81e26590e4 Update PY_VERSION to indicate that we're beyond 2.3a2 now. 2003-02-20 18:46:54 +00:00
Michael W. Hudson 2aec8b744e As far as I can tell PyEval_GetOwner was removed in 1997 (when it was
called something else!).  I can't imagine removing the prototype is
going to hurt, but put it back if *you* can.

Guido van Rossum 6297a7a9fb - PyEval_GetFrame() is now declared to return a PyFrameObject *
instead of a plain PyObject *.  (SF patch #686601 by Ben Laurie.)

Tim Peters 1441cf9dfc Bump version # to 2.3a2. 2003-02-18 21:58:53 +00:00
Guido van Rossum 4b499dd3fb - Finally fixed the bug in compile() and exec where a string ending
with an indented code block but no newline would raise SyntaxError.
  This would have been a four-line change in parsetok.c...  Except
  codeop.py depends on this behavior, so a compilation flag had to be
  invented that causes the tokenizer to revert to the old behavior;
  this required extra changes to 2 .h files, 2 .c files, and 2 .py
  files.  (Fixes SF bug #501622.)

Jeremy Hylton 985eba53f5 Small function call optimization and special build option for call stats.
-DCALL_PROFILE: Count the number of function calls executed.

When this symbol is defined, the ceval mainloop and helper functions
count the number of function calls made.  It keeps detailed statistics
about what kind of object was called and whether the call hit any of
the special fast paths in the code.

Optimization:

When we take the fast_function() path, which seems to be taken for
most function calls, and there is minimal frame setup to do, avoid
call PyEval_EvalCodeEx().  The eval code ex function does a lot of
work to handle keywords args and star args, free variables,
generators, etc.  The inlined version simply allocates the frame and
copies the arguments values into the frame.

The optimization gets a little help from compile.c which adds a
CO_NOFREE flag to code objects that don't have free variables or cell
variables.  This change allows fast_function() to get into the fast
path with fewer tests.

I measure a couple of percent speedup in pystone with this change, but
there's surely more that can be done.

Jeremy Hylton 4f0dcc9a9a Provide __module__ attributes for functions defined in C and Python.
__module__ is the string name of the module the function was defined
in, just like __module__ of classes.  In some cases, particularly for
C functions, the __module__ may be None.

Change PyCFunction_New() from a function to a macro, but keep an
unused copy of the function around so that we don't change the binary
API.

Change pickle's save_global() to use whichmodule() if __module__ is
None, but add the __module__ logic to whichmodule() since it might be
used outside of pickle.

Tim Peters 5b8132ffa3 _PyLong_NumBits(): The definition of this was too specific to the quirky
needs of pickling longs.  Backed off to a definition that's much easier
to understand.  The pickler will have to work a little harder, but other
uses are more likely to be correct <0.5 wink>.

_PyLong_Sign():  New teensy function to characterize a long, as to <0, ==0,
or >0.
2003-01-31 15:52:05 +00:00
Tim Peters baefd9e552 Added new private API function _PyLong_NumBits. This will be used at the
start for the C implemention of new pickle LONG1 and LONG4 opcodes (the
linear-time way to pickle a long is to call _PyLong_AsByteArray, but
the caller has no idea how big an array to allocate, and correct
calculation is a bit subtle).

Raymond Hettinger 7b8e281997 SF bug #670229: doc improvement for cStringIO.h
Gernot Hillier added more detail to the internal API documentation.

Jack Jansen b2a57722a8 It turns out that some calls return AEDesc records that are "borrowed",
the AEDesc data shouldn't be disposed when the Python object is.

Added a C call AEDesc_NewBorrowed() to create these objects and a Python
method old=AEDesc.AutoDispose(onoff) to change auto-dispose state.

Tim Peters a9bc168f95 Got rid of the internal datetimetz type. 2003-01-11 03:39:11 +00:00
Tim Peters a032d2eb7f Minor fiddling to make the next part easier. Introduced an internal
HASTZINFO() macro.
2003-01-11 00:15:54 +00:00
Tim Peters 37f398282b Got rid of the timetz type entirely. This was a bit trickier than I
hoped it would be, but not too bad.  A test had to change:
time.__setstate__() can no longer add a non-None tzinfo member to a time
object that didn't already have one, since storage for a tzinfo member
doesn't exist in that case.

Jason Tishler fb8595df4f Patch #661760: Cygwin auto-import module patch
The attached patch enables shared extension
modules to build cleanly under Cygwin without
moving the static initialization of certain function
pointers (i.e., ones exported from the Python
DLL core) to a module initialization function.

Additionally, this patch fixes the modules that
have been changed in the past to accommodate
Cygwin.

Neal Norwitz dc392e3143 Move _PyInt_Init() into pythonrun.h, since all the other _Init()
functions are here.  Suggested by Skip.

Neal Norwitz c91ed400e0 SF #561244, Micro optimizations
Initialize the small integers and __builtins__ in startup.
This removes some if conditions.
Change XDECREF to DECREF for values which shouldn't be NULL.

Just van Rossum 52e14d640b PEP 302 + zipimport:
- new import hooks in import.c, exposed in the sys module
- new module called 'zipimport'
- various changes to allow bootstrapping from zip files

I hope I didn't break the Windows build (or anything else for that
matter), but then again, it's been sitting on sf long enough...

Regarding the latest discussions on python-dev: zipimport sets
pkg.__path__ as specified in PEP 273, and likewise, sys.path item such as
/path/to/Archive.zip/subdir/ are supported again.

Tim Peters 4643bd9a9c Apparently FreeBSD enables some HW floating-point exceptions by default.
This can cause core dumps when Python runs.  Python relies on the 754-
(and C99-) mandated default "non-stop" mode for FP exceptions.  This
patch from Ben Laurie disables at least one FP exception on FreeBSD at
Python startup time.

Neal Norwitz 802926482c Provide mechanism to deprecate functions, types, and struct members.
It would be nice to support other compilers besides gcc.

Tim Peters 2a799bf77a datetime escapes the sandbox. The Windows build is all set. I leave it
to others to argue about how to build it on other platforms (on Windows
it's in its own DLL).

Tim Peters bca1cbc6f8 SF 548651: Fix the METH_CLASS implementation.
Most of these patches are from Thomas Heller, with long lines folded
by Tim.  The change to test_descr.py is from Guido.  See the bug report.

Not a bugfix candidate -- METH_CLASS is new in 2.3.

Jack Jansen 26897bf138 Fix for #641455: curses module doesn't build on MacOSX. It turns out the
system headers have two declarations for wchar_t, with different guard macros.

Not sure whether this is a bugfix candidate, that depends on what changed in the
curses module.

Neil Schemenauer 89350a41b9 Remove _Py_ResetReferences. Fixes bug #529750 "Circular reference makes
Py_Init crash".  refchain cannot be cleared because objects can live across
Py_Finalize() and Py_Initialize() if they are kept alive by circular
references.

Mark Hammond c2e85bd4e2 Patch 594001: PEP 277 - Unicode file name support for Windows NT. 2002-10-03 05:10:39 +00:00
Guido van Rossum e5de77800e Back out the previous change. It doesn't save any space on 64-bit
platforms.
2002-09-17 03:27:02 +00:00
Guido van Rossum 73d66925d9 Rearrange the members of struct _node to put shorter fields towards
the end, in the hope of saving some bytes on 64-bit machines.  (Too
bad n_nchildren can't be made an unsigned short, but
test/test_longexp.py specifically tests for more than 2**16 subtrees
at one level.)

I don't expect any binary compatibility issues here, unless someone
has an old binary of parsermodule.so saved away.
2002-09-17 03:24:09 +00:00
Neil Schemenauer 96aa0acef0 Use Py_GCC_ATTRIBUTE instead of __attribute__. Compilers other than GCC
might use __attribute__ in other ways (e.g. CodeWarrior).

Michael W. Hudson 02ff6a9952 A slight change to SET_LINENO-less tracing.
