* typing: Add more tests for TypeVar (#104571)Jelle Zijlstra2023-05-172-7/+49
| | | | | | | | 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.

* gh-102153: Start stripping C0 control and space chars in `urlsplit` (#102508)Illia Volochii2023-05-172-1/+72
| | | | | | | | | `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 Metcalfe2023-05-162-15/+170
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#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. Fixes #103861 --------- Co-authored-by: Gregory P. Smith <greg@krypto.org>
* gh-69152: add method get_proxy_response_headers to HTTPConnection class ↵Alexey Namyotkin2023-05-162-9/+30
| | | | | | | | | | (#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.

| | | | | | | | | | | | | zoneinfo tests (#22863) These are stubs to be used for adding hypothesis (https://hypothesis.readthedocs.io/en/latest/) tests to the standard library. When the tests are run in an environment where `hypothesis` and its various dependencies are not installed, the stubs will turn any tests with examples into simple parameterized tests and any tests without examples are skipped. It also adds hypothesis tests for the `zoneinfo` module, and a Github Actions workflow to run the hypothesis tests as a non-required CI job. The full hypothesis interface is not stubbed out — missing stubs can be added as necessary. Co-authored-by: Zac Hatfield-Dodds <zac.hatfield.dodds@gmail.com>

A logical no-op on all known platforms today as os.altsep is currently only set to a meaningful value on Windows (where it is "/").

* GH-90208: Suppress OSError exceptions from `pathlib.Path.glob()` (GH-104141)Barney Gale2023-05-112-46/+25
| | | | | | | | | | | `pathlib.Path.glob()` now suppresses all OSError exceptions, except those raised from calling `is_dir()` on the top-level path. Previously, `glob()` suppressed ENOENT, ENOTDIR, EBADF and ELOOP errors and their Windows equivalents. PermissionError was also suppressed unless it occurred when calling `is_dir()` on the top-level path. However, the selector would abort prematurely if a PermissionError was raised, and so `glob()` could return incomplete results.

* gh-104263: Rely on Py_NAN and introduce Py_INFINITY (GH-104202)Sebastian Berg2023-05-104-6/+15
| | | | | | | | | | This PR removes `_Py_dg_stdnan` and `_Py_dg_infinity` in favour of using the standard `NAN` and `INFINITY` macros provided by C99. This change has the side-effect of fixing a bug on MIPS where the hard-coded value used by `_Py_dg_stdnan` gave a signalling NaN rather than a quiet NaN. --------- Co-authored-by: Mark Dickinson <dickinsm@gmail.com>
