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).
Classes that don't use __slots__ have a __weakref__ member added in
the same way as __dict__ is added (i.e. only if the base didn't
already have one). Classes using __slots__ can enable weak
referenceability by adding '__weakref__' to the __slots__ list.
Renamed the __weaklistoffset__ class member to __weakrefoffset__ --
it's not always a list, it seems. (Is tp_weaklistoffset a historical
misnomer, or do I misunderstand this?)
specified in the uu header already exists. No additional
workaround is provided since out_file=pathname is a deprecated
interface, so it is better to simply pass a file-like object into
out_file anyway. This closes SF bug #438083.
Use isinstance() tests instead of type comparisons.
#449043 supporting __future__ in simulated shells
in support of PEP 264.
Much has changed from the patch version:
+ Repaired bad hex constant for nested_scopes.
+ Defined symbolic CO_xxx names so global search will find these uses.
+ Made the exported list of feature names explicit, instead of abusing
__all__ for this purpose (and redefined __all__ accordingly).
+ Added gross .compiler_flag verification to test___future__.py, and
reworked it a little to make use of the newly exported explicit list
of feature names.
is pickled as a global must now exist by the name under which it is
pickled, otherwise the pickling fails. Previously, such things would
fail on unpickling, or unpickle as the wrong global object. I'm
hoping that this won't break existing code that is playing tricks with
this.
I need a volunteer to do this for cPickle too.
- 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.
expression. This is needed for certain servers that (in violation of
the standard) don't return the parentheses in the response.
This fixes SF bug #441712 by Henrik Weber (not exactly using his
patch).
local module tables (the lists of modules documented within a chapter,
inserted at the beginning of the chapter). If this is not done here,
the text is not part of the resulting documents when latex2html does the
processing normally.
This fixes a little bit more of SF bug #451556.
the class dict). Anything but a nonnegative int in either place is
*ignored* (before, a non-Boolean was an error). The default is still
static -- in a comparative test, Jeremy's Tools/compiler package ran
twice as slow (compiling itself) using dynamic as the default. (The
static version, which requires a few tweaks to avoid modifying class
variables, runs at about the same speed as the classic version.)
slot_tp_descr_get(): this also needed fallback behavior.
slot_tp_getattro(): remove a debug fprintf() call.
when an unbound method of class A is stored as a class variable of
class B, and class B is *not* a subclass of class A, that method
should *not* get bound to B instances.
the metatype passed in as an argument. This prevents infinite
recursion when a metatype written in Python calls type.__new__() as a
"super" call.
Also tweaked some comments.
calculate it on the fly. This way even modules with long package
names get an accurate repr instead of a truncated one. The extra
malloc/free cost shouldn't be a problem in a repr function.
Closes SF bug #437984
+ test_compare. While None compares less than anything else, it's not
always the case that None has the smallest id().
+ test_descr. The output of %p (pointer) formats varies across platforms.
In particular, on Windows it doesn't produce a leading "0x".
the "#ifdef MS_WINDOWS" to "#ifdef SELECT_USES_HEAP" and by
setting SELECT_USES_HEAP when FD_SETSIZE > 1024.
The indirection seems useful since this subtly changes the path
that "normal" Windows programs take (where Timmie sez FD_SETSIZE =
512). If that's a problem for Windows, he has only one place to
change.
parameter, but did not. This was found because it can create failures
elsewhere based on the presence of mime.types files in some common locations
the module searches by default.
(I will be writing a test for this module shortly!)
optimization for dynamic classes. If __getattr__ is not found as an
attribute on the type, slot_tp_getattro replaces itself with
PyObject_GenericGetAttr. This means you can't add a __getattr__
method to a class after the fact -- but you can still *change* a
__getattr__ method into a different one.
(A similar restriction exists for classic classes.)
