the wrong number of arguments or duplicate keyword arguments are supplied.
Comes with more tests for test_extcall.py and and an update to an error
message in test/output/test_pyexpat.
re-initializing Python (Py_Finalize() followed by Py_Initialize()) to
blow up quickly. With the DECREF removed I can't get it to fail any
more. (Except it still leaks, but that's probably a separate issue.)
1) "from M import X" now works even if M is not a real module; it's
basically a getattr() operation with AttributeError exceptions
changed into ImportError.
2) "from M import *" now looks for M.__all__ to decide which names to
import; if M.__all__ doesn't exist, it uses M.__dict__.keys() but
filters out names starting with '_' as before. Whether or not
__all__ exists, there's no restriction on the type of M.
- Make error messages from issubclass() and isinstance() a bit more
descriptive (Ping, modified by Guido)
- Couple of tiny fixes to other docstrings (Ping)
- Get rid of trailing whitespace (Guido)
Cygwin Python DLL and Shared Extension Patch). Add module.dll as a
valid extension.

an empty keywords dictionary (via apply() or the extended call syntax),
the keywords dict should be ignored. If the keywords dict is not empty,
TypeError should be raised. (Between the restructuring of the call
machinery and this patch, an empty dict in this situation would trigger
a SystemError via PyErr_BadInternalCall().)
Added regression tests to detect errors for this.
More revision still needed.
Much of the code that was in the mainloop was moved to a series of
helper functions. PyEval_CallObjectWithKeywords was split into two
parts. The first part now only does argument handling. The second
part is now named call_object and delegates the call to a
call_(function,method,etc.) helper.
XXX The call_XXX helper functions should be replaced with tp_call
functions for the respective types.
The CALL_FUNCTION implementation contains three kinds of optimization:
1. fast_cfunction and fast_function are called when the arguments on
the stack can be passed directly to eval_code2() without copying
them into a tuple.
2. PyCFunction objects are dispatched immediately, because they are
presumed to occur more often than anything else.
3. Bound methods are dispatched inline. The method object contains a
pointer to the function object that will be called. The function
is called from within the mainloop, which may allow optimization #1
to be used, too.
The extened call implementation -- f(*args) and f(**kw) -- are
implemented as a separate case in the mainloop. This allows the
common case of normal function calls to execute without wasting time
on checks for extended calls, although it does introduce a small
amount of code duplication.
Also, the unused final argument of eval_code2() was removed. This is
probably the last trace of the access statement :-).
"..." in "from M import ..." was never DECREFed. Leak reported by
James Slaughter and nailed by Barry, who also provided an earlier
version of this patch.
the bug report (for details, look at it), but agree there's no need for Python
to declare atof itself: we #include stdlib.h, and ANSI C sez atof is declared
there already.
regardless of whether the system getopt() does what we want. This avoids the
hassle with prototypes and externs, and the check to see if the system
getopt() does what we want. Prefix optind, optarg and opterr with _PyOS_ to
avoid name clashes. Add new include file to define the right symbols. Fix
Demo/pyserv/pyserv.c to include getopt.h itself, instead of relying on
Python to provide it.
When a method is called with no regular arguments and * args, defer
the first arg is subclass check until after the * args have been
expanded.
N.B. The CALL_FUNCTION implementation is getting really hairy; should
review it to see if it can be simplified.
by making the DUP_TOPX code utterly straightforward. This also gets rid
of all normal-case internal DUP_TOPX if/branches, and allows replacing one
POP() with TOP() in each case, so is a good idea regardless.
Do not assume that all platforms using a MetroWorks compiler can use
POSIX threads; the assumption breaks on BeOS. This fix only helps
for BeOS.
This closes SourceForge patch #101772.
unintentionally caused them to get written in text mode under Windows.
As a result, when .pyc files were later read-- in binary mode --the
magic number was always wrong (note that .pyc magic numbers deliberately
include \r and \n characters, so this was "good" breakage, 100% across
all .pyc files, not random corruption in a subset). Fixed that.
Add definitions of INT_MAX and LONG_MAX to pyport.h.
Remove includes of limits.h and conditional definitions of INT_MAX
and LONG_MAX elsewhere.
This closes SourceForge patch #101659 and bug #115323.
Add three new convenience functions to the PyModule_*() family:
PyModule_AddObject(), PyModule_AddIntConstant(), PyModule_AddStringConstant().
This closes SourceForge patch #101233.
"s#" will now return a pointer to the default encoded string data
of the Unicode object instead of a pointer to the raw UTF-16
data.
The latter is still available via PyObject_AsReadBuffer().
The patch also adds an optimization for string objects which is
based on the fact that string objects return the raw character data
for getreadbuffer access and are always single-segment.
