mark all tests requiring Python 2 Summary: This diff marks ALL mercurial tests requiring Python 2 feature. After you fixes some tests, simply remove the `py2` feature requirement and that tests will be continuously run after your diff is landed. To bypass this feature requirement, run the tests command with `HGTEST_FORCE_PY2=1`. For example: ``` HGTEST_FORCE_PY2=1 buck test //eden/scm/tests:hg_run_tests ``` or ``` HGTEST_FORCE_PY2=1 python run-tests.py ``` ---- Basically this diff are created with the following commands: ``` $ sed -i 's/import feature\(.\)$/import feature\1\n\nfeature.require(["py2"])/' test--t.py $ sed -i '1s/^/#require py2\n/' test-.t $ ls \| grep -P "^test.(?<\!-t)\.py$" > list && vim -p $(cat list) # manually adding feature requires for these Python tests. ``` (Note: this ignores all push blocking failures!) ignore-conflict-markers Reviewed By: singhsrb Differential Revision: D19655148 fbshipit-source-id: 985e3ccb4010cc559049f1d89f8909bc2d9b5e20 2020-01-31 05:40:49 +03:00			`feature.require(["py2"])`
