* GH-73991: Add `pathlib.Path.copytree()` (#120718)Barney Gale2024-06-231-0/+3
| | | | | | | | | | | | | | | | | | | | Add `pathlib.Path.copytree()` method, which recursively copies one directory to another. This differs from `shutil.copytree()` in the following respects: 1. Our method has a *follow_symlinks* argument, whereas shutil's has a *symlinks* argument with an inverted meaning. 2. Our method lacks something like a *copy_function* argument. It always uses `Path.copy()` to copy files. 3. Our method lacks something like a *ignore_dangling_symlinks* argument. Instead, users can filter out danging symlinks with *ignore*, or ignore exceptions with *on_error* 4. Our *ignore* argument is a callable that accepts a single path object, whereas shutil's accepts a path and a list of child filenames. 5. We add an *on_error* argument, which is a callable that accepts an `OSError` instance. (`Path.walk()` also accepts such a callable). Co-authored-by: Nice Zombies <nineteendo19d0@gmail.com>

* gh-112346: Document the OS byte in `gzip.compress` output change in 3.11 ↵Gregory P. Smith2024-06-171-0/+15

* GH-73991: Add `pathlib.Path.copy()` (#119058)Barney Gale2024-06-141-0/+7
| | | | | | | | | | | | | | | Add a `Path.copy()` method that copies the content of one file to another. This method is similar to `shutil.copyfile()` but differs in the following ways: - Uses `fcntl.FICLONE` where available (see GH-81338) - Uses `os.copy_file_range` where available (see GH-81340) - Uses `_winapi.CopyFile2` where available, even though this copies more metadata than the other implementations. This makes `WindowsPath.copy()` more similar to `shutil.copy2()`. The method is presently _less_ specified than the `shutil` functions to allow OS-specific optimizations that might copy more or less metadata. Incorporates code from GH-81338 and GH-93152.

* gh-118934: Fix PyEval_GetLocals docs (PEP 667) (#119932)Alyssa Coghlan2024-06-021-8/+28
| | | | | | | | | | | | | PEP 667's description of the planned changes to PyEval_GetLocals was internally inconsistent when accepted, so the docs added for gh-74929 didn't match either the current behaviour or the intended behaviour once gh-118934 is fixed. This PR updates the documentation and 3.13 What's New to match the intended behaviour (once gh-118934 is fixed). It also tidies up lingering references to `f_locals` always being a dictionary (this hasn't been true since at least when custom namespace support for class statement execution was added)

* gh-60191: Implement ast.compare (#19211)Batuhan Taskaya2024-05-221-0/+7
| | | | | | | | | | * bpo-15987: Implement ast.compare Add a compare() function that compares two ASTs for structural equality. There are two set of attributes on AST node objects, fields and attributes. The fields are always compared, since they represent the actual structure of the code. The attributes can be optionally be included in the comparison. Attributes capture things like line numbers of column offsets, so comparing them involves test whether the layout of the program text is the same. Since whitespace seems inessential for comparing ASTs, the default is to compare fields but not attributes. ASTs are just Python objects that can be modified in arbitrary ways. The API for ASTs is under-specified in the presence of user modifications to objects. The comparison respects modifications to fields and attributes, and to _fields and _attributes attributes. A user could create obviously malformed objects, and the code will probably fail with an AttributeError when that happens. (For example, adding "spam" to _fields but not adding a "spam" attribute to the object.) Co-authored-by: Jeremy Hylton <jeremy@alum.mit.edu>
