Based this PR on the recent earlier upgrade at #97006 by @corona10

Issue: Upgrade bundled expat to 2.5.0 #98739

Most changes to Python require a NEWS entry.

Please add it using the blurb_it web app or the blurb command-line tool.

scdub · 2022-10-27T02:02:46Z

@hartwork I'm not sure if there are other changes that you think would be necessary for Python to upgrade to your latest release, but here's a first attempt at to get Python synced up. I believe there is a constellation of security fixes which Python will be requiring in the near term (SQLite, OpenSSL, ...) and this could potentially tag along for one of those releases.

hartwork · 2022-10-27T14:47:47Z

@scdub I don't really understand your message. Can you maybe rephrase your question for me to better understand?

@scdub I don't really understand your message. Can you maybe rephrase your question for me to better understand?

I applogize, I wasn't clear. I noticed that with 2.5.0, there is a new EXPAT_CONFIG_H definition for preventing multiple inclusions and wasn't sure if there was any changes required for pyexpatns.h or they can remain independent approaches.

hartwork · 2022-10-27T18:16:18Z

@scdub thanks for elaborating. The added EXPAT_CONFIG_H protection originally came up in relation to refactoring the test suite that triggered compiler warnings on redefining existing macros. I think it can safely be ignored in context of CPython.

scdub · 2022-10-27T18:26:55Z

@gpshead I'm not sure if this PR is of interest to you, but saw that you did initiate the work for the previous expat upgrade to 2.4.9.

gpshead · 2022-10-27T20:43:25Z

Confirmed that these match the libexpat 2.5.0 upstream sources from SHA256(expat-2.5.0.tar.xz)= ef2420f0232c087801abf705e89ae65f6257df6b7931d37846a193ef2e8cdcbe

with our pyexpatns.h addition and that this adds no new C APIs that need including in that "namespace" header hack.

Thanks @scdub for the PR, and @gpshead for merging it 🌮🎉.. I'm working now to backport this PR to: 3.7, 3.8, 3.9, 3.10, 3.11.
