- The copy module now "copies" function objects (as atomic objects).
- dict.__getitem__ now looks for a __missing__ hook before raising
KeyError.
- Added a new type, defaultdict, to the collections module.
This uses the new __missing__ hook behavior added to dict (see above).
atomically, but deepcopy() didn't support this at all.
I don't see any reason for this, so I'm adding ClassType
to the set of types that are deep-copied atomically.
metaclasses.
This is essentially the same problem as that reported in bug 494904
for pickle: deepcopy should treat instances of custom metaclasses the
same way it treats instances of type 'type'.
Bugfix candidate.
Straightforward fix. Will backport to 2.2. If there's ever a new 2.1
release, this could be backported there too (since it's an issue with
anything that's got both a __reduce__ and a __setstate__).
rexec.
When using a restricted environment, imports of copy will fail with an
AttributeError when trying to access types.CodeType.
Bugfix candidate (all the way back to 1.5.3, but at least 2.1.3 and
2.2.1).
deepcopy(), _reconstruct(): pass the memo to the other function, so
that recursive data structures built out of new-style objects may be
deeply copied correctly.
2.2.1 bugfix!
fallback for objects that are neither supported by our dispatch table
nor have a __copy__ or __deepcopy__ method.
Changes to _reduce() in copy_reg.py to support reducing objects that
don't have a __dict__ -- copy.copy(complex()) now invokes _reduce().
Add tests for copy.copy() and copy.deepcopy() to test_regrtest.py.
- 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.
added test script and expected output file as well
this closes patch 103297.
__all__ attributes will be added to other modules without first submitting
a patch, just adding the necessary line to the test script to verify
more-or-less correct implementation.
*this* set of patches is Ka-Ping's final sweep:
The attached patches update the standard library so that all modules
have docstrings beginning with one-line summaries.
A new docstring was added to formatter. The docstring for os.py
was updated to mention nt, os2, ce in addition to posix, dos, mac.
the memo) to avoid a certain kind of nasty crash. (Not easily
reproducable because it requires a later call to __getinitargs__() to
return a tuple that happens to be allocated at the same address.)
