Source: python-oauth2client Severity: important Dear Maintainer,
Building (or running autopkgtest) for python-oauth2client against flask 3.0 leads to an error when running the test-suite: Traceback: oauth2client/contrib/flask_util.py:173: in <module> from flask import _app_ctx_stack E ImportError: cannot import name '_app_ctx_stack' from 'flask' (/usr/lib/python3/dist-packages/flask/__init__.py) With previous versions of flask, the same code would produce a warning instead: oauth2client/contrib/flask_util.py:173: DeprecationWarning: '_app_ctx_stack' is deprecated and will be removed in Flask 2.3. Flask decided to remove the deprecated _app_ctx_stack [1] in 3.0.0. The recommended approach is to "use 'g' to store data instead." Quote from Version 2.2.0 changelog [2]: > The app and request contexts are managed using Python context vars directly > rather than Werkzeug’s LocalStack. This should result in better performance > and memory use. #4682 > > Extension maintainers, be aware that _app_ctx_stack.top and > _request_ctx_stack.top are deprecated. Store data on g instead using a unique > prefix, like g._extension_name_attr. > Nowadays oauth2client is marked deprecated [3] and the upstream repository [4] has been read only for four years. NOTE: When building with python3.12, there are other errors but they have already been reported as part of bug 1058392 [5] Thank you [1] https://github.com/pallets/flask/pull/5223 [2] https://flask.palletsprojects.com/en/2.3.x/changes/#version-2-2-0 [3] https://google-auth.readthedocs.io/en/latest/oauth2client-deprecation.html [4] https://github.com/googleapis/oauth2client [5] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1058392 -- System Information: Debian Release: trixie/sid APT prefers mantic-updates APT policy: (500, 'mantic-updates'), (500, 'mantic-security'), (500, 'mantic'), (100, 'mantic-backports') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.1.0-16-generic (SMP w/8 CPU threads; PREEMPT) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
