* gh-113538: Revert "gh-113538: Add asycio.Server.{close,abort}_clients ↵Guido van Rossum2024-03-121-5/+0
| | | | | | | | | | (#114432)" (#116632) Revert "gh-113538: Add asycio.Server.{close,abort}_clients (#114432)" Reason: The new test doesn't always pass: https://github.com/python/cpython/pull/116423#issuecomment-1989425489 This reverts commit 1d0d49a7e86257ff95b4de0685e6997d7533993c.
* gh-113538: Add asycio.Server.{close,abort}_clients (#114432)Pierre Ossman (ThinLinc team)2024-03-111-0/+5
| | | | | | These give applications the option of more forcefully terminating client connections for asyncio servers. Useful when terminating a service and there is limited time to wait for clients to finish up their work.

* gh-107361: strengthen default SSL context flags (#112389)William Woodruff2024-03-061-1/+15
| | | | | | | | | | | | | This adds `VERIFY_X509_STRICT` to make the default SSL context perform stricter (per RFC 5280) validation, as well as `VERIFY_X509_PARTIAL_CHAIN` to enforce more standards-compliant path-building behavior. As part of this changeset, I had to tweak `make_ssl_certs.py` slightly to emit 5280-conforming CA certs. This changeset includes the regenerated certificates after that change.

* gh-115398: Expose Expat >=2.6.0 reparse deferral API (CVE-2023-52425) ↵Sebastian Pipping2024-02-291-0/+11
| | | | | | | | | | | | | | | | | | | | | (GH-115623) Allow controlling Expat >=2.6.0 reparse deferral (CVE-2023-52425) by adding five new methods: - `xml.etree.ElementTree.XMLParser.flush` - `xml.etree.ElementTree.XMLPullParser.flush` - `xml.parsers.expat.xmlparser.GetReparseDeferralEnabled` - `xml.parsers.expat.xmlparser.SetReparseDeferralEnabled` - `xml.sax.expatreader.ExpatParser.flush` Based on the "flush" idea from https://github.com/python/cpython/pull/115138#issuecomment-1932444270 . ### Notes - Please treat as a security fix related to CVE-2023-52425. Includes code suggested-by: Snild Dolkow <snild@sony.com> and by core dev Serhiy Storchaka.

| | | | | | | | | | | | | | | | | Add PythonFinalizationError exception. This exception derived from RuntimeError is raised when an operation is blocked during the Python finalization. The following functions now raise PythonFinalizationError, instead of RuntimeError: * _thread.start_new_thread() * subprocess.Popen * os.fork() * os.fork1() * os.forkpty() Morever, _winapi.Overlapped finalizer now logs an unraisable PythonFinalizationError, instead of an unraisable RuntimeError.

* gh-97928: Partially restore the behavior of tkinter.Text.count() by default ↵Serhiy Storchaka2024-02-111-7/+6
| | | | | | | | | | | | | (GH-115031) By default, it preserves an inconsistent behavior of older Python versions: packs the count into a 1-tuple if only one or none options are specified (including 'update'), returns None instead of 0. Except that setting wantobjects to 0 no longer affects the result. Add a new parameter return_ints: specifying return_ints=True makes Text.count() always returning the single count as an integer instead of a 1-tuple or None.
