commit 6a4488a34529a572052bbeb8ef7a49f4b724adc9 Author: Jarek Potiuk <ja...@potiuk.com> AuthorDate: Fri Mar 15 21:26:43 2024 +0100 Improve speed and stability of Python 3.12 tests in canary build Python 3.12 introduced a new (much faster) way of tracking and monitoring execution of python code by tools like coverage tracking using sysmon (PEP 669). This however also apparently heavily impacted performance of coverage tracking for Python 3.12 when PEP 669 is not used. The coverage library since 7.4.0 has an experimental support for PEP 669 that can be enabled with COVERAGE_CORE=sysmon env variable and a number of users confirmed it fixes the problem. We are using 7.4.4 coverage already so we should enable this mode to speed up our coverage tracking. That should also allow us to remove databricks from excluded providers. See https://github.com/databricks/databricks-sql-python/issues/369 for databricks case and https://github.com/nedbat/coveragepy/issues/1665 for coverage bug. --- dev/breeze/src/airflow_breeze/commands/testing_commands.py | 2 ++ 1 file changed, 2 insertions(+) diff --git a/dev/breeze/src/airflow_breeze/commands/testing_commands.py b/dev/breeze/src/airflow_breeze/commands/testing_commands.py index eceaa0a22e..cb8bd5723e 100644 --- a/dev/breeze/src/airflow_breeze/commands/testing_commands.py +++ b/dev/breeze/src/airflow_breeze/commands/testing_commands.py @@ -841,6 +841,8 @@ def helm_tests( python_version=shell_params.python, helm_test_package=helm_test_package, ) + if sys.version_info >= (3, 12): + env["COVERAGE_CORE"] = "sysmon" cmd = ["docker", "compose", "run", "--service-ports", "--rm", "airflow", *pytest_args, *extra_pytest_args] result = run_command(cmd, check=False, env=env, output_outside_the_group=True) fix_ownership_using_docker()
