* gh-123271: Make builtin zip method safe under free-threading (#123272)Pieter Eendebak2024-08-274-1/+61
| | | | | | | | | | | | | | | | The `zip_next` function uses a common optimization technique for methods that generate tuples. The iterator maintains an internal reference to the returned tuple. When the method is called again, it checks if the internal tuple's reference count is 1. If so, the tuple can be reused. However, this approach is not safe under the free-threading build: after checking the reference count, another thread may perform the same check and also reuse the tuple. This can result in a double decref on the items of the replaced tuple and a double incref (memory leak) on the items of the tuple being set. This adds a function, `_PyObject_IsUniquelyReferenced` that encapsulates the stricter logic necessary for the free-threaded build: the internal tuple must be owned by the current thread, have a local refcount of one, and a shared refcount of zero.

* GH-73991: Prune `pathlib.Path.copy()` and `copy_into()` arguments (#123337)Barney Gale2024-08-263-108/+21
| | | | | | | | | | | | | | | | Remove *ignore* and *on_error* arguments from `pathlib.Path.copy[_into]()`, because these arguments are under-designed. Specifically: - *ignore* is appropriated from `shutil.copytree()`, but it's not clear how it should apply when the user copies a non-directory. We've changed the callback signature from the `shutil` version, but I'm not confident the new signature is as good as it can be. - *on_error* is a generalisation of `shutil.copytree()`'s error handling, which is to accumulate exceptions and raise a single `shutil.Error` at the end. It's not obvious which solution is better. Additionally, this arguments may be challenging to implement in future user subclasses of `PathBase`, which might utilise a native recursive copying method.
* GH-73991: Make `pathlib.Path.delete()` private. (#123315)Barney Gale2024-08-267-287/+48
| | | | | | | | Per feedback from Paul Moore on GH-123158, it's better to defer making `Path.delete()` public than ship it with under-designed error handling capabilities. We leave a remnant `_delete()` method, which is used by `move()`. Any functionality not needed by `move()` is deleted.
* gh-111495: Remove test_capi test_rshift_print() (#123338)Victor Stinner2024-08-261-15/+0
| | | | The suggestion for "print >> value" was removed recently: commit 9375b9ca3a4998678ba74ff5c77ed540a4dcf887.

* GH-73991: Add `pathlib.Path.copy_into()` and `move_into()` (#123314)Barney Gale2024-08-266-4/+96
| | | | | | | | | | | | These two methods accept an *existing* directory path, onto which we join the source path's base name to form the final target path. A possible alternative implementation is to check for directories in `copy()` and `move()` and adjust the target path, which is done in several `shutil` functions. This behaviour is helpful in a shell context, but less so in a stored program that explicitly specifies destinations. For example, a user that calls `Path('foo.py').copy('bar.py')` might not imagine that `bar.py/foo.py` would be created, but under the alternative implementation this will happen if `bar.py` is an existing directory.

* GH-73991: Add `pathlib.Path.move()` (#122073)Barney Gale2024-08-256-4/+225
| | | | | Add a `Path.move()` method that moves a file or directory tree, and returns a new `Path` instance pointing to the target. This method is similar to `shutil.move()`, except that it doesn't accept a *copy_function* argument, and it doesn't check whether the destination is an existing directory.

* gh-117376: Make `Py_DECREF` a macro in ceval.c in free-threaded build (#122975)Sam Gross2024-08-232-27/+53
| | | | | | | | | | | `Py_DECREF` and `PyStackRef_CLOSE` are now implemented as macros in the free-threaded build in ceval.c. There are two motivations; * MSVC has problems inlining functions in ceval.c in the PGO build. * We will want to mark escaping calls in order to spill the stack pointer in ceval.c and we will want to do this around `_Py_Dealloc` (or `_Py_MergeZeroLocalRefcount` or `_Py_DecRefShared`), not around the entire `Py_DECREF` or `PyStackRef_CLOSE` call.
