Change to get/set/del slice operations so that if the object doesn't
support slicing, *or* if either of the slice arguments is not an int
or long, we construct a slice object and call the get/set/del item
operation instead. This makes it possible to design classes that
support slice arguments of non-integral types.
For the HTTPS class (when available), ensure that the x509 certificate data
gets passed through to the HTTPSConnection class. Create a new
HTTPS.__init__ to do this, and refactor the HTTP.__init__ into a new _setup
method for both init's to call.
Note: this is solved differently from the patch, which advocated a new
**x509 parameter on the base HTTPConnection class. But that would open
HTTPConnection to arbitrary (ignored) parameters, so was not as desirable.
Change several sections to subsections (part of the manual -> howto
transformation).
Flesh out discussion of assignment nodes (and delete statements).
Add an example of manipulating AST objects at a >>> prompt
somewhat less horrid hack <wink>: if a module does
from __future__ import X
then the module dict D is left in a state such that (viewing X as a
string)
D[X] is getattr(__future__, X)
So by examining D for all the names of future features, and making that
test for each, we can make a darned good guess as to which future-features
were imported by the module. The appropriate flags are then sucked out
of the __future__ module, and passed on to compile()'s new optional
arguments (PEP 264).
Also gave doctest a meaningful __all__, removed the history of changes
(CVS serves that purpose now), and removed the __version__ vrbl (similarly;
before CVS, it was a reasonable clue, but not anymore).
builtin_eval wasn't merging in the compiler flags from the current frame;
I suppose we never noticed this before because future division is the
first future-feature that can affect expressions (nested_scopes and
generators had only statement-level effects).
interpretation of negative indices, since neither the sq_*item slots
nor the slot_ wrappers do this. (Slices are a different story, there
the size wrapping is done too early.)
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.

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.
