* gh-109868: Skip deepcopy memo check for empty memo (GH-109869)Pieter Eendebak2023-09-291-5/+5

* gh-108751: Add copy.replace() function (GH-108752)Serhiy Storchaka2023-09-061-0/+13
| | | | | | | | | It creates a modified copy of an object by calling the object's __replace__() method. It is a generalization of dataclasses.replace(), named tuple's _replace() method and replace() methods in various classes, and supports all these stdlib classes.

* gh-90494: Reject 6th element of the __reduce__() tuple (GH-93609)Serhiy Storchaka2022-06-091-1/+1
| | | | | copy.copy() and copy.deepcopy() now always raise a TypeError if __reduce__() returns a tuple with length 6 instead of silently ignore the 6th item or produce incorrect result.

* bpo-40792: Make the result of PyNumber_Index() always having exact type int. ↵Serhiy Storchaka2020-05-281-0/+1
| | | | | | | | | | | | (GH-20443) Previously, the result could have been an instance of a subclass of int. Also revert bpo-26202 and make attributes start, stop and step of the range object having exact type int. Add private function _PyNumber_Index() which preserves the old behavior of PyNumber_Index() for performance to use it in the conversion functions like PyLong_AsLong().
* bpo-38293: Allow shallow and deep copying of property objects (GH-16438)Guðni Natan Gunnarsson2020-01-121-1/+2
| | | | | | | | | | | | | | | | | | Copying property objects results in a TypeError. Steps to reproduce: ``` >>> import copy >>> obj = property() >>> copy.copy(obj) ```` This affects both shallow and deep copying. My idea for a fix is to add property objects to the list of "atomic" objects in the copy module. These already include types like functions and type objects. I also added property objects to the unit tests test_copy_atomic and test_deepcopy_atomic. This is my first PR, and it's highly likely I've made some mistake, so please be kind :) https://bugs.python.org/issue38293

* Merging the py3k-pep3137 branch back into the py3k branch.Guido van Rossum2007-11-061-1/+1
| | | | | | | | | | | | | | No detailed change log; just check out the change log for the py3k-pep3137 branch. The most obvious changes: - str8 renamed to bytes (PyString at the C level); - bytes renamed to buffer (PyBytes at the C level); - PyString and PyUnicode are no longer compatible. I.e. we now have an immutable bytes type and a mutable bytes type. The behavior of PyString was modified quite a bit, to make it more bytes-like. Some changes are still on the to-do list.

* Remove duplicate refs to int from int/long unification presumably. (There ↵Neal Norwitz2007-02-271-2/+1

* - PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;Guido van Rossum2007-02-111-3/+3
| | | | | | | | | | 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.
* Fix most trivially-findable print statements.Guido van Rossum2007-02-091-17/+17
| | | | | | | | | 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.)

* - Patch 1433928:Guido van Rossum2006-02-251-1/+3
| | | | | | | | - 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).

* Add support for copy_reg.dispatch_table.Guido van Rossum2003-02-071-48/+50
| | | | | Rewrote copy() and deepcopy() without avoidable try/except statements; getattr(x, name, None) or dict.get() are much faster than try/except.
