epriestley a28e76b7b3 Allow "hg arc-ls-markers" to run under Python 2 or Python 3 ... Summary: Ref T13546. See PHI1805. Currently, the "arc-ls-markers" extension doesn't run under Python 3: - some stuff needs "b'...'" to mark it as a byte string; - "dict.iteritems()" is gone in Python 3, and "mercurial.pycompat" isn't always available; - in Python 3, "json" refuses to print byte strings; and - the compiler caching behavior in Python 3 has changed. Try to get these things working in the same way under Python 2 and Python 3. Test Plan: Ran this command (with `python` as Python 2, locally): ``` $ python /usr/local/bin/hg --config 'extensions.arc-hg=/Users/epriestley/dev/core/lib/arcanist/support/hg/arc-hg.py' arc-ls-markers -- ``` ...and this command: ``` $ python3 /usr/local/bin/hg --config 'extensions.arc-hg=/Users/epriestley/dev/core/lib/arcanist/support/hg/arc-hg.py' arc-ls-markers -- ``` ..and saw the same output in both cases (previously, `python3 ...` fataled in various ways).
