wireproto: use %d to encode int, not %s Differential Revision: https://phab.mercurial-scm.org/D1102

wireproto: use a proper exception instead of `assert False` Differential Revision: https://phab.mercurial-scm.org/D1101

wireproto: use listcomp instead of map() The latter returns a generator object on Python 3, which breaks various parts of hg that expected a list. Differential Revision: https://phab.mercurial-scm.org/D1100

dagutil: use a listcomp instead of a map() In Python 3, the map() returns a generator object instead of a list, and some parts of hg depend on this being consumable more than once or sortable in place. Differential Revision: https://phab.mercurial-scm.org/D1099

peer: when collecting method names for batch calls, bytes-ify __name__ This will explode violently if we have a non-ascii command name. That shouldn't ever happen in core, and seems unlikely even in third-party code. Regardless, it'll explode violently, so we can revisit things in the future if we need to change the encoding here.

python3: replace im_{self,func} with __{self,func}__ globally These new names are portable back to Python 2.6. Differential Revision: https://phab.mercurial-scm.org/D1091

httppeer: extract content-type from headers using native str Differential Revision: https://phab.mercurial-scm.org/D1090

httppeer: convert request url back to bytes before inspecting it Differential Revision: https://phab.mercurial-scm.org/D1089

templater: explode if we try to emit a str Without this if branch, we infinitely recurse in _flatten, which is very confusing. Something in an hgweb template is trying to write out a string instead of a bytes on Python 3, and this at least makes it crash politely. Differential Revision: https://phab.mercurial-scm.org/D1088

hgweb: fill in content-type and content-length as native strings This lets me actually get a capabilities response from hgweb over http. Differential Revision: https://phab.mercurial-scm.org/D1087
