From 48c76dcbb1c0b47d87b033f19c75f5f22c6d2f5a Mon Sep 17 00:00:00 2001 From: "sanjeev.kumar" Date: Sun, 21 Sep 2025 01:03:29 +0530 Subject: [PATCH] feat: upgrade umongo for Python 3.12 compatibility MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Upgrade pymongo to >=4.6 to support Python 3.12 - Replace deprecated Motor cursor APIs: next_object() and fetch_next → async for / next() - Replace deprecated asyncio.get_event_loop() with new event loop fixture - Remove or fix other Python 3.12 incompatibilities and deprecation warnings --- HISTORY.rst | 4 +-- azure-pipelines.yml | 6 ++++ docs/userguide.rst | 6 ++-- setup.cfg | 4 +-- setup.py | 5 +-- tests/common.py | 4 +-- tests/frameworks/test_motor_asyncio.py | 14 ++++----- tests/frameworks/test_txmongo.py | 6 ++-- tests/test_document.py | 4 +-- tests/test_embedded_document.py | 2 +- tests/test_fields.py | 7 ++--- tests/test_marshmallow.py | 25 ++++++++------- tox.ini | 2 +- umongo/abstract.py | 10 ++++-- umongo/data_proxy.py | 8 ++--- umongo/fields.py | 8 ++--- umongo/frameworks/motor_asyncio.py | 43 +++++++++++++++++--------- umongo/frameworks/txmongo.py | 6 ++-- 18 files changed, 93 insertions(+), 71 deletions(-) diff --git a/tests/common.py b/tests/common.py index 047143b3..7e598d14 100644 --- a/tests/common.py +++ b/tests/common.py @@ -71,13 +71,13 @@ def is_compatible_with(db): class BaseTest: -
