* gh-104050: Add more type annotations to Argument Clinic (#104628)Erlend E. Aasland2023-05-181-14/+39
| | | | | | | | | | Annotate the following: - methods of class Class - methods of class Module - methods of class PythonParser - function compute_checksum() - function parse_file() - global variable unsupported_special_methods
* gh-104629: Don't skip test_clinic if _testclinic is missing (#104630)Erlend E. Aasland2023-05-181-2/+5
| | | | Just skip the tests that depend on the _testclinic extension module; we can still run the Python tests.

* gh-104050: Improve some typing around `default`s and sentinel values (#104626)Alex Waygood2023-05-181-18/+23
| | | | | | | | | | | - Convert `unspecified` and `unknown` to be members of a `Sentinels` enum, rather than instances of bespoke classes. - An enum feels more idiomatic here, and works better with type checkers. - Convert some `==` and `!=` checks for these values to identity checks, which are more idiomatic with sentinels. - _Don't_ do the same for `Null`, as this needs to be a distinct type due to its usage in `clinic.py`. - Use `object` as the annotation for `default` across `clinic.py`. `default` can be literally any object, so `object` is the correct annotation here. --- Co-authored-by: Erlend E.

* gh-104372: Cleanup _posixsubprocess `make_inheritable` for async signal ↵Gregory P. Smith2023-05-172-34/+92
| | | | | | | | | | safety and no GIL requirement (#104518) Move all of the Python C API calls into the parent process up front instead of doing PyLong_AsLong and PyErr_Occurred and PyTuple_GET from the post-fork/vfork child process. Much of this was long overdue. We shouldn't have been using PyTuple and PyLong APIs within all of these low level functions anyways.

* typing: Add more tests for TypeVar (#104571)Jelle Zijlstra2023-05-173-8/+50
| | | | | | | | During the PEP 695 implementation at one point I made TypeVar.__name__ return garbage, and all of test_typing passed. So I decided to add a few more tests. In the process I discovered a minor incompatibility from the C implementation of TypeVar: empty constraints were returned as None instead of an empty tuple.

| | | | | | | | | `urllib.parse.urlsplit` has already been respecting the WHATWG spec a bit #25595. This adds more sanitizing to respect the "Remove any leading C0 control or space from input" [rule](https://url.spec.whatwg.org/#url-parsing:~:text=Remove%20any%20leading%20and%20trailing%20C0%20control%20or%20space%20from%20input.) in response to [CVE-2023-24329](https://nvd.nist.gov/vuln/detail/CVE-2023-24329). --------- Co-authored-by: Gregory P.

* gh-103861: Fix Zip64 extensions not being properly applied in some cases ↵Carey Metcalfe2023-05-163-15/+172
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#103863) Fix Zip64 extensions not being properly applied in some cases: Fixes an issue where adding a small file to a `ZipFile` object while forcing zip64 extensions causes an extra Zip64 record to be added to the zip, but doesn't update the `min_version` or file sizes in the primary central directory header. Also fixed an edge case in checking if zip64 extensions are required: This fixes an issue where if data requiring zip64 extensions was added to an unseekable stream without specifying `force_zip64=True`, zip64 extensions would not be used and a RuntimeError would not be raised when closing the file (even though the size would be known at that point). This would result in successfully writing corrupt zip files. Deciding if zip64 extensions are required outside of the `FileHeader` function means that both `FileHeader` and `_ZipWriteFile` will always be in sync. Previously, the `FileHeader` function could enable zip64 extensions without propagating that decision to the `_ZipWriteFile` class, which would then not correctly write the data descriptor record or check for errors on close. If anyone is actually using `ZipInfo.FileHeader` as a public API without explicitly passing True or False in for zip64, their own code may still be susceptible to that kind of bug unless they make a similar change to where the zip64 decision happens.

* gh-69152: add method get_proxy_response_headers to HTTPConnection class ↵Alexey Namyotkin2023-05-164-12/+44
| | | | | | | | | | (#104248) Add http.client.HTTPConnection method get_proxy_response_headers() - this is a followup to https://github.com/python/cpython/pull/26152 which added it as a non-public attribute. This way we don't pre-compute a headers dictionary that most users will never access. The new method is properly public and documented and triggers full proxy header parsing into a dict only when actually called. --------- Co-authored-by: blurb-it[bot] <43283697+blurb-it[bot]@users.noreply.github.com> Co-authored-by: Gregory P.
