have differing refcount semantics. If anyone sees a prettier way to
acheive the same ends, then please go for it.
I think this is the first time I've ever used Py_XINCREF.
* Fixes an incorrect variable in a PyDict_CheckExact.
* Allow general mapping locals arguments for the execfile() function
and exec statement.
* Add tests.
PyImport_ReloadModule(): restore the module to sys.modules in error cases.
load_package(): semantic-neutral refactoring from an earlier stab at
this patch; giving it a common error exit made the code
easier to follow, so retaining that part.
_RemoveModule(): new little utility to delete a key from sys.modules.
__oct__, and __hex__. Raise TypeError if an invalid type is
returned. Note that PyNumber_Int and PyNumber_Long can still
return ints or longs. Fixes SF bug #966618.
The preceding case statement was missing a terminating "break" stmt,
so fell into the new code by mistake. This caused uncaught out-of-bounds
accesses to the "names" tuple, leading to a variety of insane behaviors.
expected entrypoint. The unlinking will crash the application if the
module contained ObjC code. The price of this is small: a little wasted
memory, and only in a case than isn't expected to occur often.
[ 984722 ] Py_BuildValue loses reference counts on error
I'm ever-so-slightly uneasy at the amount of work this can do with an
exception pending, but I don't think that this can result in anything
more serious than a strange error message.
[ 960406 ] unblock signals in threads
although the changes do not correspond exactly to any patch attached to
that report.
Non-main threads no longer have all signals masked.
A different interface to readline is used.
The handling of signals inside calls to PyOS_Readline is now rather
different.
These changes are all a bit scary! Review and cross-platform testing
much appreciated.
table' of the dll, to make sure that the dll really was build for the
correct Python version. It does this by looking for an entry
'pythonXY.dll' (X.Y is the Python version number).
The code now checks the size of the dll's import table before reading
entries from it. Before this patch, the code crashed trying to read
the import table when the size was zero (as in Win2k's wmi.dll, for
example).
Look for imports of 'pythonXY_d.dll' in a debug build instead of
'pythonXY.dll'.
Fixes SF 951851: Crash when reading "import table" of certain windows dlls.
Already backported to the 2.3 branch.
The builtin eval() function now accepts any mapping for the locals argument.
Time sensitive steps guarded by PyDict_CheckExact() to keep from slowing
down the normal case. My timings so no measurable impact.
Add a more informative message for the common user mistake of subclassing
from a module name rather than another class (i.e. random instead of
random.random).
(Code contributed by Jiwon Seo.)
The documentation portion of the patch is being re-worked and will be
checked-in soon. Likewise, PEP 289 will be updated to reflect Guido's
rationale for the design decisions on binding behavior (as described in
in his patch comments and in discussions on python-dev).
The test file, test_genexps.py, is written in doctest format and is
meant to exercise all aspects of the the patch. Further additions are
welcome from everyone. Please stress test this new feature as much as
possible before the alpha release.
pre-increment forms to post-increment forms. Post-incrementing
also eliminates the need for negative array indices for oparg fetches.
* In exception handling code, check for class based exceptions before
the older string based exceptions.
BINARY_SUBSCR:
* invert test for normal case fall through
* eliminate err handling code by jumping to slow_case
LOAD_LOCALS:
* invert test for normal case fall through
* continue instead of break for the non-error case
STORE_NAME and DELETE_NAME:
* invert test for normal case fall through
LOAD_NAME:
* continue instead of break for the non-error case
DELETE_FAST:
* invert test for normal case fall through
LOAD_DEREF:
* invert test for normal case fall through
* continue instead of break for the non-error case
