py3: glob over exception in test-check-py3-compat.t Python 3.6+ raise ModuleNotFoundError and older versions raise ImportError. Glob over the exception differences. For whatever reason, we were already doing this for one failure. But not all occurrences of ModuleNotFoundError were changed. Who knows. This test should now pass on all Python versions (although I didn't check Windows). Differential Revision: https://phab.mercurial-scm.org/D7939

py3: string normalization and I/O tweaks in test-lfs.t The print was inserting b'' on Python 3. In addition, since we weren't writing to the ui instance (which isn't readily available in this function), output order could get mixed up. We add some pycompat casts and a stdout flush to make the test happy on all Python versions. Differential Revision: https://phab.mercurial-scm.org/D7938
