Checkpoint for new I/O library.

Fix some silly uses of KEYS, ITEMS, VALUES.

Remove duplicate refs to int from int/long unification presumably. (There might be more refs like these.)

Remove the ability to slice/index on exceptions per PEP 352.

Tweak the fix for test_traceback since the fix for it to run on its own broke
it under regrtest. 'traceback' likes to strip out the module name if it is
__main__ or __builtin__ but not in other cases.

Fix a broken test in test_traceback where the module name was being tacked on
needlessly.

Add TODO

Remove the exceptions builtin module, all the exceptions are already builtin.

Fix another loop over a dict that may change... :-(

Add -d/--debug option to print traceback without -v/--verbose.

Make it so TypeError is raised if an instance of an object is put in an
'except' clause. Also refactor some code to help keep Neal Norwitz happy.

The raw_input name was removed, but the implementation was moved to input.
So don't declare that it was removed, just leave the original description.

raw_input() really was removed, only input() was resurrected.

Two more patches by Tony Lownds (SF# 1607548).

(1)
Combines the code paths for MAKE_FUNCTION and MAKE_CLOSURE.
Fixes a crash where functions with closures and either annotations or
keyword-only arguments result in MAKE_CLOSURE, but only
MAKE_FUNCTION has the code to handle annotations or keyword-only
arguments.
Includes enough tests to trigger the bug.

(2)
Change peepholer to not bail in the presence of EXTENDED_ARG +
MAKE_FUNCTION.
Enforce the natural 16-bit limit of annotations in compile.c.

Also update Misc/NEWS with the "input = raw_input" change.

You can no longer catch non-BaseException objects; TypeError is raised if such
an object is listed in an 'except' clause.

Whoops, fix build breakage. There were still a few uses of the bool type.
Remove the last few uses of bool/true/false.

bool is no longer required, it was only used for the print statement

........

Add raw_input() back, named input(). Revive the old unittests too.

Add a partial list of limitations, stripping out some corresponding XXX comments.

Change a test to be more predictable.
The problem with using random.random is that several modules and tests do
"from random in random" which confuses pickle.whichmodule().

Another refleak, this time in PyLong_AsLong. Fixes leaks showing in
test_getargs2 and test_email.

Use better idiom to sort keys.

Fix a refleak in the MAKE_FUNCTION opcode in ceval.c.

Fix a refleak in PyString_Format.

Fix refleaks in function objects caused by kwdefaults not being allocated.

Should func_new be extended to support a "kwdefaults" arg?

Fix leak in the print function.

Fix token.py main code vs. dict views.

Fix a bizarre error where test_pickletools fails if preceded by test_pyclbr.
The fix is in neither, but in pickle.py where a loop over sys.modules.items()
could modify sys.modules, occasionally.

Don't confound Neil S on b"a"[0] = b"b".

put a missing curly brace

These comments aren't relevant for 3k. They were to support modules compiled
before the PyNumberMethods were added which was 2.0 I think.

Fix merge bug (lost line causing syntax error).

Use Glyph's trick to ensure that __globals__ is set properly.

Add a proper unit test for xreload.py.

Change all the function attributes from func_* -> __*__. This gets rid
of func_name, func_dict and func_doc as they already exist as __name__,
__dict__ and __doc__.

  Variation of patch # 1624059 to speed up checking if an object is a subclass
  of some of the common builtin types.

  Use a bit in tp_flags for each common builtin type.  Check the bit
  to determine if any instance is a subclass of these common types.
  The check avoids a function call and O(n) search of the base classes.
  The check is done in the various Py*_Check macros rather than calling
  PyType_IsSubtype().

  All the bits are set in tp_flags when the type is declared
  in the Objects/*object.c files because PyType_Ready() is not called
  for all the types.  Should PyType_Ready() be called for all types?
  If so and the change is made, the changes to the Objects/*object.c files
  can be reverted (remove setting the tp_flags).  Objects/typeobject.c
  would also have to be modified to add conditions
  for Py*_CheckExact() in addition to each the PyType_IsSubtype check.

  Update the encoding package's search function to use absolute imports when
  calling __import__.  This helps make the expected search locations for encoding
  modules be more explicit.

  One could use an explicit value for __path__ when making the call to __import__
  to force the exact location searched for encodings.  This would give the most
  strict search path possible if one is worried about malicious code being
  imported.  The unfortunate side-effect of that is that if __path__ was modified
  on 'encodings' on purpose in a safe way it would not be picked up in future
  __import__ calls.

but the test claims to pass, so I'm ignoring these.

Fix test_bsddb3 (along with something bsddb) to work with dict views.

Fix obvious problems from switch to dict views. Some tests still fail over
some reference count issue (I think).

Remove test_dumbdbm as failing.

Fix dumbdbm and test_dumbdbm to work with dict views. Bug in dumbdbm was from
dict views not being iterators but just iterables.

Fix test_importhooks for dict views.

Fix test_iter after the dict views conversion.

Fix test_iterlen by returning the iterator of dict views. Problem is that
iteritems and itervalues' previous object were both an iterator *and* and
iterable. The tests expected an iterator but were given an iterable.

Should the 2to3 conversion for iter(values|items|keys) change the code to
``iter(dict.keys())`` to be more compatible?

Fix xml.dom.minidom so it works again after the dict views introduction.

There are some methods in minidom that return dict.keys() directly. There were
left alone since the tests passed without touching them, but it might be
prudent to just wrap them in a 'list' call to be safe for people expecting a
list.

Fix test_mutants for dict views.

Fix test_os from breakage due to dict views.

Fix plistlib to work with dict views.

Some more test now pass.

Fix the damage to UserDict and its tests.
Clearly this is not the right way to fix this; UserDict and MixinDict
ought to be redesigned with the new dict API in mind. But I'm not
claiming to be in charge of library redesign, I only want zero failing
tests.

Fix for test_dict.py, thanks to Eduardo O Padoan.

Get rid of some old TO TO items.

List of broken tests at this time. If you fix a test, please update this file.

Make dict.keys() and dict.items() comparable to sets, using == and !=.
(PEP 3106 requires subset comparisons too, those will come later if someone
really wants them. :-)

Fix unittest.

Fix another unit test.

Make test_logging pass.

Checkin the regenerated Python-ast.c and fix test_optparse.

Nailed test_weakref.py. Pfew, messy!

Two more trivial fixes.

Another fix. Partly reverted the tweaks done by the previous fix.

Make test_sax pass.

With the help of the improved fixer, test_with.py is now fixed.

- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
and .keys(), .items(), .values() return dict views.

The dict views aren't fully functional yet; in particular, they can't
be compared to sets yet. but they are useful as "iterator wells".

There are still 27 failing unit tests; I expect that many of these
have fairly trivial fixes, but there are so many, I could use help.

Random change to make this work unchanged when dict.keys() returns a dict view.

Implement __contains__ for dict_keys and dict_items.
(Not for dict_values, where it can't be done faster than
the default implementation which just iterates the elements.)

Endow dict views with a proper length method.

Very preliminary work on dict views.

News about softspace.

Fix the remaining doctest failures.
One was a modified line that was echoed in an exception;
the other two were softspace problems, fixed clumsily but effectively.

Ignore *.py[co].

Fix test_frozen.

Kill off softspace completely (except in formatter.py which seems to have
a different feature with the same name).
The change to test_doctest.txt reduces the doctest failures to 3.

Redue the failure rate to 13 tests. Bah.

Fix the roundtripping function.

Fairly subtle fix for failing tests.

Trivial fix for test_profile.py.

Found another difference between old and new print:
old print would suppress the softspace after \t.

More prints embedded in strings.

Fix a bogus end=' ' here.

Two tests fixed with one fix.

Fix another test.

Some more tests pass now. (Also test_compiler.py with -u all.)

* Remove PRINT_ITEM(_TO), PRINT_NEWLINE(_TO) opcodes.
* Fix some docstrings and one Print -> print.
* Fix test_{class,code,descrtut,dis,extcall,parser,popen,pkg,subprocess,syntax,traceback}.
These were the ones that generated code with a print statement.
In most remaining failing tests there's an issue with the soft space.

Fix an unfortunate mis-conversion: sometimes "print x," must be
converted to "print(x, end=' ')", but other times it must be converted
to "print(x, end='')". There's no easy way to find out, because it
depends on whether x ends with a newline. I'm sure I'll find more
like this.

Revert doubly-converted doctests.

Fix a bunch of doctests with the -d option of refactor.py.
We still have 27 failing tests (down from 39).

Note that print is a function now.

Fix most trivially-findable print statements.

There's one major and one minor category still unfixed:
doctests are the major category (and I hope to be able to augment the
refactoring tool to refactor bona fide doctests soon);
other code generating print statements in strings is the minor category.

(Oh, and I don't know if the compiler package works.)

Essential changes for print function changes.
Lib will be changed in a separate run.
