py3: use hex(hasher.digest()) .hexdigest() returns a system str. .digest() consistently returns bytes. Differential Revision: https://phab.mercurial-scm.org/D2159

py3: use string for "close" value in commit extras The extras dict on commits has string keys and values. Before this commit, we passed "close" as an integer, which Python 2 gladly coerced to a string during a %s formatting in the bowels of changelog.py.

py3: catch TypeError during template operations Two places in this code Python 3 changed from raising ValueError to TypeError. So catch the addition exceptions. IMO this code might be better off performing type sniffing. But I'm not sure the implications of changing that. Differential Revision: https://phab.mercurial-scm.org/D2156

py3: use bytes literals for test extension These extensions don't get run through our custom module importer. It's easy enough to make them dual compatible with Python 2 and 3. # skip-blame b prefixes Differential Revision: https://phab.mercurial-scm.org/D2155

py3: use system strings when calling __import__ We must pass the native str type when importing. Differential Revision: https://phab.mercurial-scm.org/D2154

py3: open patches.queue in binary mode And switch to using the context manager form of open() while we're here. Differential Revision: https://phab.mercurial-scm.org/D2153

py3: compare against bytes instead of str Differential Revision: https://phab.mercurial-scm.org/D2152

py3: use b'' in mockblackbox.py This unmasks a ton of other TypeError in blackbox code. # skip-blame since it's just a b prefix Differential Revision: https://phab.mercurial-scm.org/D2175

narrow: add a TODO document These are things that are bigger than we want to handle right now, but are pretty important to get narrowing to be non-experimental. Differential Revision: https://phab.mercurial-scm.org/D2196

tests: use `hello` not `capabilities` over ssh Differential Revision: https://phab.mercurial-scm.org/D2195
