* gh-123309: Remove check for redefined memo entry in pickletools.dis() ↵Serhiy Storchaka2024-08-313-24/+11
| | | | | | (GH-123374) Such pickles are supported by the Unpickler even if the Pickler does not produce them.
* gh-76960: Fix urljoin() and urldefrag() for URIs with empty components ↵Serhiy Storchaka2024-08-313-52/+140
| | | | | | | | | | | | (GH-123273) * urljoin() with relative reference "?" sets empty query and removes fragment. * Preserve empty components (authority, params, query, fragment) in urljoin(). * Preserve empty components (authority, params, query) in urldefrag(). Also refactor the code and get rid of double _coerce_args() and _coerce_result() calls in urljoin(), urldefrag(), urlparse() and urlunparse().

* gh-108172: do not override OS preferred browser if it is a super-string of a ↵Oded Arbel2024-08-312-1/+2
| | | | | | | | | | | known browser (GH-113011) When checking if the registering browser is the "OS preferred browser", do not use a substring search - that makes no sense: one can have a preferred browser that looks like a super-string of a known browser, e.g. "firefox-nightly" vs "firefox". https://github.com/python/cpython/issues/108172 explains in more detail, and lays out a potential better future enhancement for this case of just using xdg-open. We'll go with this for now. --------- Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com>

* 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
